The invention relates to novel phenyl-substituted cyclic ketoenols, to a plurality of processes and intermediates for their preparation and to their use as pesticides.
It has akready been discosed that certain phenyl-substituted cyc ketoenols are active as insectidces, acaricides and/or herbicides.
Also known are 1H-arylpyrrolidine-dione derivatives (BP-A-456 063, EP-A-521 334, EP-A-596 298, EP-A-613 884, EP-A-613 885, DE 44 40 594, WO 94/01 997, WO 95/01 358, WO 95126 954, WO 95/20 572, EP-A-0 668 267, WO 96/15 395, WO 96/35 664, WO 97/01 535 and WO 97/02 243).
It is known that certain substituted xcex943-dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4 014 420). The synthesis of the tetronic acid derivatives used as staring materials (such as, for example, 3-(2-methyl-phenyl)-4-hydroxy-5-(4-fluorophenyl)-xcex943-dihydrofuran-2-one) is likewise described in DE-A-4 014 420. Compounds of similar struftre without details of an insecticidal and/or acaricidal activity are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (S) 1567-76. Furthermore, 3-aryl-xcex943-dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are disclosed in EP-A-528 156, EP-A 0 647 637, WO 95/26345, WO 96/20 196, WO 96/25 395, WO 96/35 664, WO 97/01 535 and WO 97/02 243.
Certain phenytl-pyrone derivatives unsubstituted in the phenyl ring have already been dislosed (cf. AM. Chirazi, T. Kappe and E. Ziegler, Arch. Phatin. 309, 558 (1976) and K. -H. Boltze and K. Heidenbluth, Chem. Ber. 91, 2849), a possible utility for these compounds as pesticides not being indicated. Phenyl-pyrone dertves substituted in the phenyl ring and having herbicidal, acaricidal and insecticidal propeties are descnrbed in EP-A-588 137, WO 96/25 395, WO 96/35 664 WO 97/01 535 and WO 97/02 243.
However, the acaricidal and insecticidal activity and/or spectrum of action, and/or the toleration of the known compounds by plants, in parficular by crops, is not always satisfactory.
The invention, accordingly, provides compounds of the formula (I)

The compounds of the formula (I) can also be present, depending on the nature of the substituents, as geometric and/or optical isomers and isomer mixtures of differing composition which, if appropriate, can be separated in a customary manner. Both the pure isomers and the isomer mixtures, their preparation and use, and compositions comprising them are part of the subject matter of the present invention. In the following, for simplicity, however, compounds of the formula (I) are always referred to, although both pure compounds and, if appropriate, mixtures having different proportions of isomer compounds are intended.
Including the meanings (1) to (4) of the group Het, the following principal structures (I-1) to (I-4) result:
in which
A, B, D, G, X and Z are each as defined above.
Including the various meanings (a), (b), (c), (d), (e), (f) and (g) of the group G, the following principal structures (I-1-a) to (I-1-g) result if Het represents the group (1)
in which

which is intended to be expressed by the dashed line in the formula (I-4).
The compounds of the formulae (I-4)a and (I-4)b can be present both as mixtures and in the form of their pure isomers. Mixtures of the compounds of the formulae (I4)a and (I-4)b can, if desired, be separated by physical methods in a manner known per se, for example by chromatographic methods.
For better clarity, in the following in each case only one of the possible isomers is shown. This does not exclude the possibility that the compounds can optionally be present in the form of the isomer mixtures or in the other respective isomer form.
Including the various meanings (a), (b), (c), (d), (e), (f) and (g) of the group G, the following principal structures (I-4-a) to (I-4-g) result if Het represents the group (4)

The configuration and arrangement of stripper elements for paper shredders operating according to the cutting roller principle have undergone intensive development in the past decade. In addition to the further development of the stripper elements arranged between the cutting disks, solutions have been proposed increasingly in recent years in which additional stripper elements are provided directly on the outer diameter of the cutting disks.
These solutions prevented that cut particles stuck between strippers and cutting disks, which over time resulted in increased friction and a higher ,contact pressure and frequently led to blockage of the cutting mechanism. However, these known solutions are more complicated and expensive and, when the installed power remained the same, a reduction of the available cutting power occurred.


In the electrical distribution field, a great number of electrical or electronic devices are mounted within a switchgear cabinet, the electrical or electronic devices including for example miniature circuit breakers, residual current circuit breakers, lamps, bell transformers, timer and push buttons etc. Each of such devices includes a mounting face which is so shaped as to match with an elongated bearing rail, for example, a so-called DIN rail which has a Ω-shaped cross-section. The DIN rail is fixed by screw or nuts to a supporting portion of a cabinet frame of a switchgear. The DIN rail has oppositely-disposed side walls provided, at both free edges thereof, with outwardly extending flanges. On the mounting face of each electrical or electronic device there is obtained a U-shaped recess having, on one boundary edge thereof, an inwardly turned lip and, on the opposite boundary edge, an inwardly protruding catch urged by a spring towards the inwardly turned lip. When a device has to be mounted on the DIN rail, the inwardly turned lip is put to engage behind one outwardly extending flange, and the spring-loaded catch makes a snap fit behind the other outwardly extending flange of the DIN rail. Subsequently, the electrical terminals of such a device have to be joined one by one directly to an elongated busbar extending alongside the DIN rail. These mounting and connecting operations are rather wearisome and time-consuming because have to be repeated several times, i.e. have to performed for each of the above mentioned electrical/electronic devices. Furthermore, if it occurs that all these devices have to be moved to a new location within the cabinet, each of them has first to be electrically disconnected and then mechanically decoupled from the DIN rail. Subsequently, the screws or nuts, which previously might be covered by the electrical devices, must be unscrewed thus enabling the DIN rail to be removed and be fixed to the new desired location within the cabinet. The electrical devices can thus be remounted on the DIN rail in the new location.
It would be desirable to overcome all the above mentioned drawbacks, by providing a clamping element which is simple and cheap to manufacture, and which enables a plurality of electrical/electronic devices to be quickly and easily connected within a switchgear cabinet in a versatile way.


An integrator is a device to perform the mathematical operation known as integration. Integrators are used in a number of settings to sample data over periods of time. Integrators may be employed by laboratory equipment, test equipment, medical devices, etc. A number of different integrator circuits are known in the art.


When a catheter is placed through the skin into an anatomic structure, a certain amount of physiologic concretion usually is found to collect on the outer surface of the catheter during the period that it dwells in the body. In blood vessels, this concretion is usually fibrin or clot. In the bladder, urinary substances (uric acid, urea, blood-components, biofilm) coat the outer surface. In chest tubes, blood and fibrin material adhere to the outer surface. In the intestinal tract, biofilm and succus entericus or stool frequently form a cast on the outer surface of the tube. In the trachea, the outer surface of the tube gets coated with mucous and respiratory substances that form a cast or biofilm on the outer surface.
Thus, when such a catheter is removed from the body, some of this material is often “peeled” off of the catheter surface, and if the catheter passes through the body wall, much of this detritus is left within the anatomic structure that has been cannulated. When this is blood clot in a vessel, it can lead to clot formation with a venous embolus from a vein (usually harmless, but can lead to thrombophlebitis) or an arterial embolus, which can be more serious if it obstructs an artery downstream The GI tract can usually expel the retained material without difficulty. Clot or fibrin masses in the pleural space can be reabsorbed or cause pleural adhesions which are of little clinical consequence. Urinary debris can cause problems if over 3-4 mm in diameter if it cannot be passed via the ureter or urethra, and such catheter debris can act as a nidus for bladder stone formation. With a minitracheotomy tube, the debris falls off into the patient's trachea, where it can stimulate a coughing episode that can increase the morbidity in emphysema or chronic obstructive pulmonary disease (COPD) patients, who are the usual candidates for use of such a tube.
COPD is a slowly progressive disease of the airways that is characterized by a gradual loss of lung function. In the U.S., the term COPD includes chronic bronchitis, chronic obstructive bronchitis, or emphysema, or combinations of these conditions. It represents the fourth leading cause of death in the U.S. 12.1 million adults ages 25 and older reported being diagnosed with COPD in 2001. About 24 million adults have evidence of impaired lung function indicating that COPD is underdiagnosed. About 119,000 adults ages 25 and older died from COPD in 2000. While the COPD death rate for females more than doubled between 1980 and 2000, and the number of deaths for females surpassed the number for males in 2000, the overall age-adjusted death rate for COPD remained higher for males in 2000. The age-adjusted COPD death rate was about 46 percent higher in males than females and 63 percent higher in whites than blacks. COPD is the fourth leading cause of death in the U.S. and is projected to be the third leading cause of death for both males and females by the year 2020.
Physicians who would normally use a COPD minitracheostomy ventilation technique may avoid using the minitracheostomy tubes because of the problem of mucous plugs falling into the trachea and leading to severe coughing episodes which leave COPD patients breathless and can actually be life threatening. The consequences of such solid material falling into the trachea is analogous to the feeling we all get when we aspirate a small food particle or sip of fluid. This set of problems of retained, solid components falling into a patient's trachea, blood vessels, bladder or urinary tract has led to a need to redesign these catheters. A need exists in the art for a design of a minitracheostomy tube in the lungs or a catheter in the blood vessel, bladder or urinary tract that can be easily inserted and then removed from the patients on a regular biweekly basis without causing severe problem of mucous plugs falling into the trachea and leading to severe coughing episodes, or debris from the catheter devices causing further complications in the patient.


1. Field of the Invention
This invention relates to integrated circuit (IC) devices. Embodiments of the invention are applicable to and suitable for electronic equipment such as television receivers, video tape recorders (VTR's) and audio tape recorders, whose internal circuits are digitally controlled.
2. Description of the Prior Art
Video or audio equipment such as digital signal processing television receivers, VTRs and audio tape recorders have recently been commercialized. Most of such digital equipment uses internal bus lines common to a central processing unit (CPU), a memory, and other control circuitry. The CPU fetches control signal values for each circuit of the electronic equipment and stored in the memory, which may be a read only memory (ROM), during the normal operation and sends the fetched data to the appropriate circuit via the internal bus, which may comprise or include a so-called serial inter-integrated circuit (I.sup.2 C) bus, so as to control the operation of the internal circuit. In addition, the CPU may control the circuits in the equipment in direct response to signals supplied manually through an external keyboard or a remote controller.
Such an internal bus is conventionally either of the two-wire or three-wire type. A two-wire internal bus comprises a data transmission line and a clock transmission line. The two-wire type bus may utilize the communication system disclosed in European Patent Application No. 81201168.2 (0 051 332). On the other hand, a three-wire bus comprises a data transmission line, a clock transmisssion line, and a so-called ident signal line used to identify the nature of each data block coming over the data transmission line.
If standardized, centralized and simplified testing of the internal circuitry during assembly and servicing of such electronic equipment in which internal bus lines are installed were possible, an overall cost reduction including a reduction in manufacturing cost could be achieved.
