Title: Leakproof hemostasis valve with single valve member
Inventor: BALES THOMAS O
IPC: A61M39/00
Filed: 1987-11-09
Granted: 1991-10-22
Abstract: LEAKPROOF HEMOSTASIS VALVE WITH SINGLE VALVE MEMBER     ABSTRACT OF THE DISCLOSURE          A hemostasis valve in which the valve member is a tubular, resilient gasket which may be compressed with variable pressure to provide a variable pressure seal to an elongated member extending through the tubular bore of the gasket.  The gasket gore also defines at least one resilient, annular rib whereby the elongated member passing through the tubular gasket bore may be subjected at all times to at least a relatively low pressure seal from the resilient, annular rib, irrespective of the pressure of the variable pressure seal.  Additionally, the pressure on the gasket may be applied and released by means of a pressure member positioned against the gasket.  Means are provided permitting longitudinal motion, but preventing rotational motion, of the pressure member.  A rotatable cap is provided, with facing, mating spiral track means carried on both the inner face of the rotatable cap and outer face of the pressure member, to cause pressurizing advancement of the pressure member against the tubular gasket by rotation of the cap in one direction, and release of such pressurizing advancement by rotation of the cap in the other direction.

Abstract: There is provided a functional ZnSe:H deposited film composed of zinc atoms, selenium atoms, and at least hydrogen atoms, with the content of hydrogen atoms being 1 to 4 atomic% and the ratio of crystal grains per unit volume being 65 to 85 vol%.  It is capable of efficient doping and is stable to irradiation.  It can be made into a high conductivity p-type of n-type ZnSe:H:M film by doping.  It can be efficiently deposited on a non-single crystal substrate such as metal, glass, and synthetic resin which was incapable of efficient depositing.  Thus the invention makes it possible to form a high-functional device such as a photovoltaic element of ZnSe film on a non-single crystal substrate.

Title: Process for producing bifidogenic infant and dietetic  foods reduced in antigenicity
Inventor: HEINE WILLI
IPC: A23C9/20
Filed: 1988-09-14
Granted: 1994-02-08
Abstract: ABSTRACT          The present invention relates to a process for the production of liquid and powdered bifidogenic infant and dietetic foods that are reduced in their antigenicity.  The process, according to the invention, is characterized in that to achieve bifidogenicity, sialic acid is cleaved from milk proteins.  This cleavage is possible by hydrolysis with hydrochloric acid or a mixture of hydrochloric and phosphoric acid, and optionally with addition of citric acid.  Consequently in accordance with the invention it is possible to produce bifidogenic infant foods, particularly suitable for infants, premature and undersized babies, and those parties who cannot tolerate usual milk products.  Furthermore the process can be used for production of dietetic food, particularly for patients suffering from intestinal allergies, other allergic diseases and patients with insufficiency of liver and kidney function.

Granted: 1993-03-23
Abstract: ABSTRACT            A method and apparatus for optimizing the performance of a multiple cache system computer having separate caches for data and instructions in which all writes to the data cache are monitored.  If the address tag of the item being written matches one of a list of tags representing valid instructions currently stored in the instruction cache, a flag called I_FLUSH_ON_REI is set. Until this flag is set, REI (Return from Exception or Interrupt) instructions will not flush the instruction cache.  When the flag is set, an REI command will also flush or clear the instruction cache.  Thus, the instruction cache is only flushed when an address referenced by an instruction is modified, so as to reduce the number of times the cache is flushed and optimize the computer's speed of operation.
