Patent CA-2060236-A1 (CA)
Title: Mattress support
Inventor: WESEMANN ROLF
IPC: A47C23/06
Filed: 1992-01-29
Abstract: Abstract The invention relates to a mattress support in the form of a slatted frame for  a bed, having individually mounted support slats which are arranged transversely relative to the lying surface and together form the resting surface for a mattress, for example.         To improve the adaptability under loading, the following features are proposed according to the inven-tion: a)   the lifting element (6) of each support slat (1) is a self-supporting and upright bellows, the air-receiving space of which is constructed to be rigid in its cross-sectional contour and to be variable only in respect of its height and, in its effective length relative to the support slat (1), to be proportional to the associated load; b)   the kinematic coupling (10, 11, 15, 16) consists of a pneumatic coupling which connects all the lifting elements (6) to one another and comprises an air distributor (15, 16) provided with an integrated damping (17, 18, 19), to which air distributor all the bellows are connected via an air connection (11) in each case; c)   each support slat (1) rests directly on its associated bellows via a support slat bearer (5), which bellows is of slightly narrower construction than the support slat bearer (5);     d)   each support slat bearer (5) is guided in a forced parallel guide (7, 8, 9) which ensures its parallel displacement relative to itself.

Title: System for scanning a surgical laser beam
Inventor: FOUNTAIN WILLIAM D
IPC: B23K26/08
Filed: 1991-08-08
Abstract: In a laser beam delivery system for a surgical laser beam, steering and scanning of the laser beam along the target (20) in transverse (X and Y) directions is accomplished in a mechanically simple and fast-responding manner. Closely adjacent to the objective lens assembly (24) of the delivery system is a pair of prisms (12, 14), i:e. Risley prism Ar Herschel prism; positioned on the axis (16) of the approaching laser beam (18). The two prisms are mounted on separate rotating stages whereby they may be individually rotated about the beam axis. Co-rotation of the prisms produces circular scans, in diameters depending on the angle between the prisms. Counter rotation of the prisms at equal speeds will produce a diametric line scan. Any desired complex scan pattern can be achieved using combinations of rotations of the prisms. Axial compactness and proximity to the objective lens as-sembly assure that virtually all of the angularly emerging beam from the prism pair passes through the objective lens assembly.

Title: Multi-layer fluid curtains for furnace openings
Inventor: SHARMA SUDHIR K
IPC: F27D99/00
Filed: 1992-07-03
Abstract: An apparatus and method for providing a selected atmosphere at and within an opening to the interior volume of a furnace.  Two or more paralleled diffusers adjacent to the furnace opening laminarly emit different fluids and provide a multi-layer fluid curtain over the opening.  The curtain has a composite modified Froude number from 0.05 to 10, and a thickness at emission of at least 5% of its extent in the flow direction.  Partially covering the outside of the curtain is an optional, substantially flat, outer shield with an aperture coinciding with the furnace opening, which reduces the necessary flow rates of fluids.  Optional side shields around the sides of the curtain also reduce the necessary fluid flow.         A preferred diffuser comprises a porous tube in a housing with an outlet directed to emit fluid across the furnace opening.  The outlet is covered with a screen to disperse the fluid flow and to protect the porous tube.

Filed: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE     An anti-theft device for a vehicle propelled by an internal combustion engine consisting of a body adapted to be interposed in a fuel line supplying fuel to the internal combustion engine.  The body has a primary fuel flow passage, and a solenoid valve having a plunger movable between a retracted position and an extended position upon receiving a signal from a hidden or coded activator.  The plunger stops the flow of fuel through the primary fuel flow passage in the extended position thereby starving the combustion engine of fuel.  The improvement consists of a secondary fuel passage through the body which bypasses the solenoid valve.  The flow of  fuel  through  the  secondary  fuel  passage  enables  the combustion engine to operate at an idle when the plunger of the solenoid valve in an extended position.

Abstract: This invention provides novel recombinant plasmids which can be used to clone heterologous genes in E. coli and to clone and express such genes in mammalian cells. These plasmids contain a number of unique restriction sites that can be used to facilitate the deletion or replacement of genetic elements and the insertion of heterologous genes in the plasmids. The nature and placement of the unique sites is such that regeneration of the sites following endonuclease cleavage can readily be achieved with a minimum of manipulative effort. Host cells containing the recombinant plasmids are also provided by this invention.

Title: Peptides for the production of preparations for the diagnosis and therapy of systemic lupus
Inventor: ZEPPEZAUER MICHAEL
IPC: C12P21/08
Filed: 1992-09-16
Abstract: Peptides having antigenic or immunogenic determinants are proposed which are recognised by autoantibodies, in particular in body fluids of patients who suffer from systemic lupus erythematosus (SLE). The two peptides are preferably the C-terminus of H1 containing the sequence section 187 - 211 and the N-termini of H2B containing the sequence sections 1 - 35 and 36 - 76 which exhibit cross-reactions with the autoantibodies (anti-histone antibodies). The invention additionally indicates routes for the formation of monoclonal antibodies and anti-idiotypic antibodies which are directed against the autoantibodies. The diagnosis of SLE can be carried out according to the invention with increased safety and the monoclonal antibodies directed against the autoantibodies are also suitable for the preparation of means for the therapy of SLE.

Title: Semiconductor device having polysilicon thin-film
Inventor: YAMAGUCHI MICHIYA
IPC: H01L29/786
Filed: 1993-02-22
Abstract: In the crystal structure of a polysilicon thin film having a field effect mobility µFE of about 80 cm2/V~sec, a grain size is about 200 nm and a crystallite size on the (111) plane is about 180 nm. The crystal size corresponds to the size of a completely monocrystallized portion of a grain.  The condition of obtaining a field effect mobility µFE of about 80 cm2/V~sec is that the crystallite size on the (111) plane is at least 180 nm (measured value).  By taking the crystallite size into consideration, it becomes possible to achieve a high field effect mobility µFE which cannot be obtained merely by increasing the grain size.
