Patent CA-2000429-A1 (CA)
Title: Gas tank container
Inventor: HOUSTON ROBERT S
IPC: F17C13/08
Filed: 1989-10-11
Abstract: ABSTRACT    A container for enclosing a liquified gas tank protects the tank from rough handling and prevents the corrosion from exposure to the atmosphere.  The container comprises a vertical cylindrical shell with bottom cap attached thereto, formed of resilient plastic non-combustible material, the inside diameter of the shell being greater that the outside diameter of the gas tank; removable friction fit lid fitted to the top of the shell, adapted to lift off under internal pressure in the shell, impact absorbing bottom pad on the inside of the bottom cap to support the gas tank; at least one impact absorbing side pad between the shell and the gas tank to support the tank within the shell, with passage for gas to vent down from the top of the gas tank to the bottom cap of the shell, and gas vent in the bottom cap of the shell to vent gas out of the shell.

Title: Foamable molding compositions
Inventor: WHITE ROGER J
IPC: C08J9/10
Filed: 1989-10-23
Abstract: Mo3132 FOAMABLE MOLDING COMPOSITIONS  ABSTRACT OF THE DISCLOSURE Summary of the Invention A Chemical Blowing Agent (CBA) concentrate was developed comprising a modifying agent and a chemical blowing agent.  The CBA is characterized in that its decomposition products contain a primary amine.  The modifying agent is a blend of a maleic anhydride copolymer and a butadiene based rubber. It was surprisingly found that resin degradation which often accompanies foam moldings using a CBA of the present type and is expressed in terms of a reduction in the molecular weight of the resin, is much reduced upon the incorporation of the modifying agent and chemical blowing agent of the invention.  The concentrate may optionally further comprise a polymeric resin component.     Mo3132

Title: Servo-controlled expansion valve for a volatile fluid
Inventor: VALBJORN KNUD V
IPC: F25B41/06
Filed: 1990-06-15
Abstract: Abstract A servo-controlled expansion valve for a volatile fluid is disclosed, particularly for use in an electronically controlled            injec-tion of refrigerant in the evaporator of refrigeration installations.          The expansion valve comprises a main valve (21) which is actuatable by a controlled pilot valve arrangement (6) by way of a servo arrangement in which the fluid serves as pressure medium. When  the  pilot valve arrangement is actuated by the fluid as pressure medium, there is the danger that the fluid evaporates in the operating chamber. The com-pressibility of the vapour can lead to oscillations which also cause the     main  valve  (21) to oscillate.  These  oscillations are  to be avoided.  For this  purpose,  the  servo arrangement  (24)  is  thermally connected to the outlet side (2) of the main valve(21).     Fig.1

Abstract: The sample liquids analysis system includes a probe which is automatically operable to successively aspirate sample liquids and reagent and/or other sample liquids processing liquids and to dispense the same in turn into sample liquids analysis apparatus for automatic, successive sample liquids analyses. Isolation liquid supply apparatus are operatively associated with the sample liquids aspirating the dispensing probe and operate to introduce an isolation liquid which is immiscible with the sample liquids and which selectively wets the probe to the substantial exclusion of the sample liquids, to the probe to, in combination with operatively associated rinse liquid supply apparatus which operate to fill the probe with a rinse liquid between successive sample liquids aspirations, reduce sample liquids carryover to ultra low levels. The sample liquids aspirating and dispensing probe are operated by the rinse liquid supply apparatus; and comprise a probe body member, and an active probe component operatively connected thereto by a readily disconnectable connector, thus making possible the ready and convenient replacement of the active probe component without adverse effect upon the essential configuration and/or operational characteristics of the rinse liquid supply apparatus, and thereby upon the overall performance of the sample liquids analysis system. The configuration of the probe operates to reduce sample liquids flow velocity in the active probe component, thereby further reducing sample liquids carryover.
