Title: Bar code entry method for computer operations
Inventor: MEEHAN MICHAEL M
IPC: G06F9/06
Filed: 1992-12-23
Abstract: ABSTRACT     An easy, rapid method for the entry and manipulation of data using bar code technology is presented.     Briefly, the operational commands commonly used in the input  of  data  into  a  particular laboratory  instrument computer system are assigned bar code designations.  These bar codes are then printed on a card which can be mounted, temporarily or permanently, on the laboratory instrument, and can be subsequently read by a bar code reader, thereby permitting  the  user  to  provide  instructions  to  the instrument without the need for a keyboard interface.
Patent CA-2086990-A1 (CA)
Inventor: STRAUB IMMANUEL
IPC: F16L17/04
Filed: 1993-01-08
Abstract: A pipe coupling includes a contractible housing 10, which receives an elastomer sealing sleeve 32 of C-shaped cross section, having sealing lips 36 extending towards each other. A meander-like spring ring 44, which is U-shaped in cross section and is provided with slots 74, is inserted in to the respective annular groove 42 in order to support the sealing lip 36 against the sleeve bar 34. Upon the contraction of the housing 10, the sleeve 32 is upended in the peripheral direction and the sealing lips 36 are brought to bear snugly against the pipe wall 55. At the same time, the spring ring 44 contracts as a result of a decrease in the width of the slots 74. The sealing lip 36 is supported by the spring ring 44 over a large area, and the flowing of material of the sleeve 32 in and through the slots 74 is prevented. The spring leg 68 projecting over the sealing lip 36 prevents any sticking of the torus 56 to the sleeve bar 34. This pipe coupling is suitable for use under high operating temperatures and large temperature changes.

Title: Immune system stabilizers for prevention and therapy of disorders associated with immune system dysfunction
Inventor: HOFFMANN GEOFFREY W
IPC: C07K14/74
Filed: 1991-07-11
Abstract: Substances that bind to alloimmune-immunogen-absorbed (AIA) sera have been found to be effective in the prevention and therapy of autoimmune disease. It is conjectured that the mechanism involves indirect stimulation of suppressor T cells resulting in stabilization of the immune system. The administration of such substances is expected to be useful in the prevention and treatment of diseases that involve a failure of the immune system to distinguish adequately between self and nonself, including autoimmune diseases and immunodeficiency diseases.

Patent CA-2100280-A1 (CA)
Inventor: TRAVERS RICHARD H
IPC: F25D1/00
Filed: 1993-07-12
Abstract: The invention pertains to an auxiliary outside air refrigeration system for use in combination with a conventional refrigeration system to supply refrigeration to an enclosure whereby cold outside air is used as the cooling medium. A differential thermostatic controller monitors the temperature inside the enclosure and in theoutside atmosphere and, if the temperature inside the enclosure indicates the need for refrigeration, activates the fans of the auxiliary outside air system whenever the temperature differential between inside and outside indicates adequate potential for refrigeration. The conventional refrigeration system is energized only when the more energy-efficient outside air refrigeration system is not able to maintain adequate refrigeration within the enclosure. The controller can be used for an auxiliary outside air refrigeration system using direct exchange of air between the enclosure and the outside atmosphere or one using an air-to air heat exchanger.

Title: Process for production of flexible laminate
Inventor: SHARPE RICHARD A
IPC: A41D31/02
Filed: 1992-05-18
Abstract: 2103373 9220533 PCTABS00017 The invention relates to a process for the production of a flexible laminate. The process comprises applying to a surface of a flexible substrate a curable composition in fluid form and comprising a plastics material as a pattern which can provide a desired image or imaging effect. Then, a metal foil bearing a holographic image and having a layer of plastics size is positioned with the size layer overlying the pattern while the composition remains fluid. Next there is applied to the combination sufficient heat and pressure at a level and for a time to adhere the foil to the substrate via the plastics material but insufficient to destroy the holographic effect. Thereafter excess foil not adhered to the substrate is removed to expose the desired image or imaging effect.  The result is a flexible laminate having a flexible holographic image which can be machine washable.

Patent CA-2106292-A1 (CA)
Title: Free-flying tubular vehicle
Inventor: MURRAY STEPHEN B
IPC: F02K7/10
Filed: 1993-09-15
Abstract: ABSTRACT OF THE DISCLOSURE        A relatively low drag, completely free-flying, tubular vehicle comprises a body that defines a leading edge and a trailing edge and includes an external surface and an internal surface each extending from the leading to the trailing edge.          The internal surface has an axially converging upstream section extending from the leading edge to a discontinuity that constitutes a throat in the vehicle.  The internal surface also has an axially diverging downstream section extending from the throat to the trailing edge.  The internal surface is configured to enable introduction and mixing of fuel into an airstream flowing therethrough, and to generate a shock wave when in flight.  The shock wave is of such magnitude and direction as to create a hot spot that subsequently causes ignition and combustion of the fuel-air mixture.  The combustion causes formation of a detonation bubble and migration of the associated wave front upstream to stabilize slightly downstream of the throat.  The combustion of the fuel  results in rapid expansion of combustion products, generating forward thrust against the internal surface of the vehicle.

Title: Slide surface construction formed of aggregate of fe crystals having body-centered cubic structure
Inventor: FUJISAWA YOSHIKAZU
IPC: F02F5/00
Filed: 1993-12-06
Abstract: A slide surface construction is formed of an aggregate of Fe  crystals  having  a  body-centered  cubic  structure.  The aggregate includes at least one of two types of metal crystals: selected from the group consisting of (1)  (h00) oriented metal crystals with their (h00) planes (by Miller indices) oriented toward a slide  surface and having a content S  in a range represented by S < 25%, and (2)  (3hh0) oriented metal crystals with their  (3hh0) planes  (by Miller indices)  oriented toward the slide surface and having a content S in a range represented by S < 25%. If both the types of the oriented Fe crystals are present, a large number of trigonal pyramid-shaped Fe crystals are  precipitated  in  the  slide  surface,  thereby  providing improved oil retention and initial conformability.  Thus,  the slide  surface  construction  exhibits  an  excellent  seizure resistance.
