Title: Holographic rear window stoplight
Inventor: MOSS GAYLORD E
IPC: G03H1/28
Filed: 1988-01-04
Granted: 1993-05-18
Abstract: ABSTRACT OF THE INVENTION An improved holographic rear window stoplight is provided and includes a hologram member laminated to the rear window surface.  Single or multiple hologram layers may be provided.  The hologram layers can have a diffraction grating developed in a position relative to the other diffraction grating to provide a folded reflec-tion of light from a source of light of an appropriate wavelength band to indicate a stoplight from a predeter-mined angle.  Alternatively predetermined indicia can be selectively displayed in either a single or multiple layer configuration.  The reflection hologram member is transparent when not in use to all observers and remains transparent to the driver even when in use, and thereby prevents any blocking of his field of view.

Abstract: ABSTRACT    Autoimmune diseases are the result of an immune response directed against a self antigen. Susceptibility to an autoimmune disease is conferred by antigen encoded within an allele of the MHC.  A potentially susceptible individual is protected from developing the autoimmune disease by an antigen encoded within a second allele of the MHC.  Individuals who have the allele for susceptibility, and lack the allele for protection are highly susceptible to manifestation of the autoimmune disease.  The present invention provides a method for prophylactically treating individuals who are highly susceptible to an autoimmune disease.  In the method, the individuals are tolerized by administration of a protective antigen encoded within the protective allele.  As part of the invention, the sequences encoding the protective antigen(s), as well as the antigen(s) conferring susceptibility, are elucidated. The elucidation of these sequences allows for the synthesis of the antigens conferring these traits. These antigens may be used pharmacologically; in addition, they may be used to raise monoclonal antibodies.  Monoclonal antibodies to these antigens are useful in diagnosis of susceptibility, and in elucidating the mechanisms by which antigens control the manifestation of the autoimmune disease.  In addition, the sequences data allow the synthesis of nucleotide probes which are also useful in diagnosis of susceptibility to the autoimmune disease.

Title: Method of making a body, and article comprising the body
Inventor: CHEN HO S
IPC: H01B13/00
Filed: 1989-01-06
Granted: 1993-12-28
Abstract: METHOD OF MAKING A BODY, AND ARTICLE       COMPRISING THE BODY Abstract Disclosed is a broadly applicable method for making an article that comprises a superconductive oxide a body, including a thin layer on a substrate,or powder particles. In a preferred embodiment, the method composes forming a precursor melt and contacting at least a part of the melt with oxygen such that the concentration of oxygen in the part of the melt increases to a critical concentration, resulting in formation of the desired oxide, substantially without drop in temperature. The precursor melt comprises at least one metallic element M, and at least the part of the melt is at a temperature T, with Tm < T < To, where Tm is the freezing temperature of the melt and To is the melting temperature of the superconductive oxide. In an exemplary embodiment the melt consists essentially of Yb, Bat and Cu in 1:2:3 atomic ratio, T is about 900°C. A layer of superconductive oxide on a SrTiO3 substrate is formed by dipping the hot (900°C) substrate into the melt, exposing the melt-coated substrate to oxygen such that oxygenation and solidification of the coating results, and furnace cooling the coated substrate in oxygen. The thus produced coating has composition YbBa2Cu3O9-.delta.(.delta. - 2.1), is essentially single phase, strongly textured, has Tc of about 85K and Jc of about 3x104 A/cm2. An aspect of the invention is the fact that the precursor melt need not be stoichiometric. For instance, we have formed a layer of composition YbBa2Cu3O7 from a melt of composition Yb2BaCu. The ability to practice the inventive method with non-stoichiometric precursor melts makes it possible to produce Y-containing bodies (e.g., YBa2Cu3O7 films on a copper substrate). The inventive technique can produce compositionally essentially homogeneous material. It is readily adaptable to produce ceramics (including high Tc superconductors) and other materials (e.g., AlN) in a variety of shapes (including wire tape, and powders) by a variety of techniques (including continuous processing). The inventive method can also be used to form a superconductive bond between two pre-existing ceramic superconductive bodies.

Abstract: Abstract Accelerator for an indirectly operating air brake The accelerator of an indirectly operating air brake has a bleed valve (30) which vents the main air line at the start of the braking operation.  This bleed valve (30) is opened by an actuating member (1) by means of an unlatchable intermediate link (10).  The design of an intermediate link can be greatly simplified by the use of a rotationally symmetrical tappet (10) which is swivelled into its operational position by a spring (11) and out of said operational position by a breaker piston (16).  At one end this tappet (10) has a cam (13) and a conical surface (15).            (Fig. 1)

Granted: 1993-01-12
Abstract: WE54,176 Abstract of the Disclosure Faults  in a three-phase power  transmission line are identified by vectorially subtracting from the postfault current for each phase, the zero sequence current and the prefault  current.   The  resultant currents which  are  the vectorial  sums  of  the  postfault  positive  and  negative sequence currents are then compared.   If the magnitude of the resultant current in one phase exceeds that in each of the other two phases by a preselected factor, that one phase is identified as the phase to ground faulted phase.  If the magnitudes of the resultant currents of two phases exceed that of the third, those two phases are involved in either a phase to phase or a phase to phase to ground fault with the distinction  being  made by  the  presence  of  zero  sequence current in the later case.
