Granted: 1992-07-28
Abstract: HA399 Abstract PROCESS FOR PREPARING 7-OXABICYCLOHEPTANE AMINO-ALCOHOL INTERMEDIATES USEFUL IN MAKING THROMBOXANE A2 RECEPTOR ANTAGONISTS AND NOVEL INTERMEDIATES PRODUCED THEREIN A process is provided for preparing a 7-oxabicycloheptane amino alcohol intermediate of the general structure or HA399 (wherein the above structures represents (D) or (L) isomers) which is useful in preparing thromboxane A2 receptor antagonists. This intermediate is prepared by reacting mesoanhydride with an aryl amine wherein R is alkyl, CH2OH, CO2H or CO2alkyl, to form the acid HA399 which is reduced by treatment with lithium aluminum hydride or diisobutylaluminum hydride or Red-Al to form the alcohol wherein R1 is CH2OH when R is CO2H, CO2alkyl or CH2OH, and R1 is alkyl when R is alkyl; where in the above alcohol R1 is CH2OH, such alcohol compound is treated with an alkyl chloroformate in the presence of base such as an alkali metal alkoxide to form the alcohol which undergoes cleavage by treatment with alkali metal, ammonia and acid to form the amino alcohol intermediate. Where in the above alcohol R1 is alkyl, that is HA399 such alcohol may be hydrogenated to form the aminoalcohol intermediate. All of the above 7-oxabicycloheptane compounds are novel and also form part of the present invention.

Title: Passivation of metal contaminated cracking catalysts
Inventor: JOHNSON MARVIN M
IPC: C10G11/18
Filed: 1987-09-15
Granted: 1992-10-27
Abstract: ABSTRACT This invention comprises improvements to processes for the catalytic cracking of hydrocarbon feedstocks. One such improvement to catalytic cracking processes provides compositions comprising metals passivating agents having an increased degree of stability. These compositions comprise aqueous suspensions of antimony by vinyl copolymers, aqueous suspensions of antimony oxide by diesters of phosphoric acid, or aqueous suspensions of antimony oxide by cellulose derivatives. Another improvement to catalytic cracking processes provides a process for reducing the viscosity of liquid suspensions of metals passivating agents without substantially reducing the stability of the liquid suspension by the utilization of at least two different particle ranges of metals passivating agents. A further improvement to catalytic cracking processes provides an efficient utilization of metals passivating agents by introducing the selected agent into the catalyst regeneration cycle of a catalytic cracking unit.

Abstract: NON-BUNCHING CINCH RING FOR SELF-APPLIED BLOOD PRESSURE CUFF                   Abstract of the Disclosure A self-adjusting  blood pressure  cuff  assembly.   A cinch ring at the fixed end of the blood pressure cuff assembly has  at  least  one  lateral  extension  disposed  away  from the direction of the fixed end of the flexible belt of the cuff assembly.   The longitudinal extension has two longitudinally directed sides.   Placing reinforcing stitches closely adjacent the  longitudinally  directed  sides  substantially  restricts transverse movements  of  the cinch ring with  respect  to  the flexible band.  In a preferred embodiment, a tag piece, passing through the slot of the cinch ring and covering the lateral extension,  is reinforced stitched to the outward cover of the elongated flexible band of the blood pressure cuff assembly. In this way, an end of an inflatable bladder can be caused to be adjacent to the loop of material forming the fixed end of the flexible band.  The bladder can be placed between the skin of the person wearing the blood pressure cuff assembly and the lateral extension of the cinch ring in order to eliminate any discomfort  caused  by  pressing  the  longitudinal  extension against the person.

Abstract: ABSTRACT A semiconductor device in which at least a part of each of the current flow paths extending from the electrode pads of the semiconductor chip to the outer terminals of the semiconductor package is made of superconducting material.  During operation, when an overcurrent applied to a lead pin exceeds the critical current of the superconducting material, the resistance is increased from zero, and the semiconductor chip is thereby protected from damage.  The superconducting material may also be configured between the outer terminals of the semiconductor package so that a potential difference can be measured.  Also, a magnetic field may be applied to the superconducting material so that the critical current value can be set.

Granted: 1993-02-23
Abstract: ABSTRACT OF THE DISCLOSURE      A liquid container comprising a main member, a cylinder and a container body. The main member has a barrel, a head fitted in an upper portion of the barrel, a discharge section provided at an upper end of the head, a passage cylinder communicating with the discharge section and extended downwardly into the upper portion of the barrel, a cylindrical piston formed at a lower end of the passage cylinder, and a resilient discharge valve in the passage cylinder. The cylinder is movably inserted into the barrel to be elevationally movably engaged with an outer surface of the lower portion of the passage cylinder and to be resiliently urged downwardly. The cylinder has a suction valve at its lower end thereof.   The container body is movably inserted into the barrel. The container has a neck portion is tightly engaged with an outer surface of a lower portion of the cylinder.          The container has a slidable bottom plate. A lower end of the container body is closed by a bottom cover. A hammer is elevationally movably inserted into a gap between the bottom cover and the slidable bottom plate. When the container is strongly axially fluctuated, the hammer hits the slidable bottom plate to apply an impact to the slidable bottom plate. Thus, the slidable bottom plate is intruded by the impact into the container body. The liquid in the container body is pressurized by the intrusion of the slidable bottom plate, air bubbles adhered to the ball valve body of the suction valve are thus compressed and isolated from the ball valve body, again mixed within the liquid, and discharged together with the liquid through the discharge valve.
