Title: 9-halogen prostaglandins, processes for their manufacture and useas pharmaceuticals
Inventor: RADUECHEL BERND
IPC: C08B37/16
Filed: 1986-03-21
Granted: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides 9-halo-15-cycloalkyl prostaglandin derivatives of formula I                           (I) where R1 is hydrogen or methyl, R2 is fluorine or chlorine, n is 0 or 1 and, wherein R1 is hydrogen, their salts with physiologically tolerable bases or their cyclodextrin cla-thrates; processes for their manufacture and pharmaceutical compositions containing them.  The 15-cycloalkyl prostag-landins of formula I in accordance with the invention are outstanding because of their properties typical of PGD2, i.e. they bind well to the PGD2 receptor, but poorly to the PGE2 and PGI2 receptor.  Investigations of cattle coronary arteries and the pulmonary artery or rabbits likewise indicate an effective PGD2 profile of formula I compounds. The compounds lower blood pressure in rats after intravenous infusion.  The compounds of the invention inhibit the secretion of gastric acid, display a cytoprotective and ulcer-healing effect and thus counteract the undesirable consequences of nonsteroidal antiphlogistics (prostaglandin synthesis inhibitors).  They have the effect of regulating cardiac-rhythm disorders and inhibiting the aggregation of platelets.

Abstract: DISC BRAKE PARKING CARTRIDGE RETENTION DEVICE         ABSTRACT OF THE DISCLOSURE The disc brake (10) includes a parking cartridge device  (28) which  transfers  reaction  forces  of  the mechanical parking actuator (36) directly to the caliper housing (12) and also provides support and guidance for a cable (90) attached to lever arms (70) of the mechanical parking actuator  (36).   The mechanical parking actuator (36)  is disposed within an opening (34)  of the parking cartridge housing  (30),  the  parking  cartridge  housing (30) having a plurality of through openings (42) so that bolts (50) may be secured at one end to the caliper hous-ing (12) and at the other end to a bracket  (60) which abuts an end (33) of the parking cartridge housing (30). An end plug (48) encloses the opening (34) and abuts the bracket (60) so that reaction forces from the mechanical parking actuator  (36)  are  transmitted  directly  to  the bracket (60), bolts (50), and caliper housing (12),  and the parking cartridge housing (30) does not receive any reaction  forces  so  that  it may be  made  of  a  lighter weight  material  and  of  a  smaller  construction.   The mechanical parking actuator (36) includes a pair of lever arms  (70)  which  are  clasped  together  by  a  U-shaped retainer (80) or pin (100) which secure the cable (90) to the lever arms (70).

Abstract: Genetic modification of a plant cell is described.      A plant structural gene is inserted into T-DNA comprising a T-DNA promoter. The promoter and the plant structural gene are in a position and orientation with respect to each other wherein the T-DNA promoter is upstream from the plant structural gene in the direction of transcription, and within a sufficiently close distance therefrom such that the plant structural gene is expressible in a plant cell under control of the T-DNA promoter. The T-DNA promoter/plant structural gene combination so formed is transferred into a plant cell for expression of the plant structural gene.

Abstract: AUXILIARY AIR CONDITIONING, HEATING AND ENGINE WARMING SYSTEM FOR TRUCKS                          ABSTRACT    A small lightweight auxiliary power plant including an engine, electrical alternator, water pump, air conditioning compressor and a heat exchanger is mounted at a convenient location on the tractor of a truck or other large vehicle. The main engine of the truck operates the existing truck air conditioning and heating system in a normal manner when the main engine is running.  When the main engine of the truck is not operating and the smaller engine of the auxiliary power plant  is operating,  the  truck air conditioning and heating system is operated by the auxiliary power plant.  The heat exchanger of the auxiliary power plant then utilizes the heat of exhaust gases generated by the auxiliary power plant engine to warm the truck engine during the time it is not operating so that easy starting of the truck engine is made possible even in very cold regions.   The electrical alternator of the auxiliary power plant supplies electrical power for the truck electrical system when the truck engine is not running.  The truck storage batteries serve the electrical systems of the truck and the auxiliary power plant.  The auxiliary power plant serves as an emergency back-up system if the truck alternator or compressor should fail.  The arrangement reduces air pollution caused by operation of the truck engine for long periods of time while the truck is stopped.   Provision can be made for warming the fuel tanks and fuel lines to prevent fuel gelling in cold climates.

Title: Gravitational separation

Abstract: ABSTRACT OF THE DISCLOSURE          A shaking  table  for  ore-dressing,  having  riffles (50) on its deck,  (10),  has uniform planar orbital motion imposed on it to cause the riffles to oscillate,  and for a standing wave system (71) to be created between the riffles.          The  continued planar  orbital  shear  forces  acting  on  the standing wave system causes sharp separation of the material fractions which are discharged continuously from the deck.          The  slope  of  the  deck  and  riffles  and  the configuration of the riffles are critical.  The slope of the deck is set empirically by estimating the approximate slope appropriate to the parameters of the material being treated and of  the  motion  imparted  to  the  deck;  and  the  final adjustment is made by slewing the deck in its own plane to obtain an optimum result.      For a frusto-conical deck, the  adjustment  is made on a flat deck and the frusto-conical deck  is constructed accordingly.          The deck may have rectilinear or curvilinear motion imparted to it, superimposed upon the orbital motion.

Abstract: ABSTRACT:         The present invention provides a cylindrical alkaline battery comprising a positive electrode case of a cylindrical form having an opening at one end and accom-modating an electricity-generating element comprising a positive electrode, a negative electrode, a separator and an alkaline electrolytic solution, an insulating gasket provided at the opening of the positive electrode case, a bottom plate being the negative electrode terminal provided on the gasket, and a heat-shrinkable member such as shrink tube or the like covering the outer surface of the positive electrode case.  In this battery, the opening end of the positive electrode case and the outer surface of the battery extending therefrom are covered with an electrical insulating film.  The presence of the electrical insulating film prevents the exterior short circuit between the positive electrode case and the bottom plate being the negative electrode terminal which may occur when the metal material of the case opening is exposed by the peeling or abnormal shrinkage of the heat-shrinkable member.         The present invention also provides a cylind-rical alkaline battery comprising a reinforcing washer provided between the bottom plate being the negative electrode terminal and the gasket.  In this battery, electric insulation is established between the bottom plate being the negative electrode terminal and the washer or between the gasket and the washer and the presence of the electric insulation cuts off the possible electric reaction route forming a local cell and prevents the resultant leakage of the electrolytic solution.
