Patent CA-2081925-A1 (CA)
Inventor: LECHNER DAVID M
IPC: F16L29/02
Filed: 1992-11-02
Abstract: A valve insert (40) is adapted to be removably mounted as a unit on a cylinder valve (41) to selectively enable a flow of fluid therethrough when a male cou-pling section (52) is inserted into the outlet of the cylinder valve. The improved insert includes a tubular body (55), a valve member (58) mounted for sealed sliding movement relative to the body, biasing means (97) and a docking member (59) mounted on the valve element and adapted to engage the nose of the male section.  When the malesection engages the insert and displaces a sealing cushion (80) off its seat (72), the pressure of fluid will urge the valve element (58) into tighter sealed engagement with the male section.

Title: Refrigerant-cooled downhole tool and method
Inventor: SCHULTZ ROGER L
IPC: E21B47/01
Filed: 1993-07-07
Abstract: Abstract of the Disclosure A downhole  tool comprises an apparatus  including an electrical  member  and  a  cooling  system  to maintain  the electrical member within a rated temperature operating range. The cooling system includes a container holding a refrigerant.          The cooling system also includes heat transfer elements for conducting refrigerant from the container in proximity to the electrical  member  so  that  a  temperature adjacent  the electrical member is less than ambient well bore temperature and preferably less than the maximum of the rated temperature operating range.  The cooling system further includes a device for moving refrigerant from the container and through the heat transfer elements in response to pressure in the well bore.          In a preferred embodiment, the refrigerant is recycled through the heat transfer circuit back to the container.  A method of reducing temperature adjacent an electrical portion of a downhole tool comprises:   discharging a refrigerant from a chamber in the downhole tool in response to pressure of a fluid in a well so that refrigerant flows from the chamber through an expansion valve and an evaporator; and transferring to refrigerant  passing through the  evaporator  heat  from adjacent the electrical portion of the downhole tool.

Title: Purification of hapten-carrier generated antibodies
Inventor: COHEN HUGETTE
IPC: G01N33/53
Filed: 1993-07-22
Abstract: PURIFICATION OF HAPTEN-CARRIER GENERATED ANTIBODIES                      ABSTRACT           In the commonly used method to obtain antibodies to small molecules, a combination of a highly antigenic carrier, such as bovine serum albumin, and the small molecule is injected into a host animal.  The recovered crude serum or plasma then contains, in addition to the desired small molecule antibodies, much  larger  amounts  of  carrier-induced  antibodies.  These unwanted antibodies are efficiently removed from the crude serum or plasma, by contacting the crude serum or plasma with the carrier material in an immobilized high surface area form.  Rapid and efficient anticarrier antibody removal results, with minimal loss of both desired antibody, and desired antibody activity.
Patent CA-2105201-A1 (CA)
Inventor: BEACH STANLEY H
IPC: F24C3/02
Filed: 1993-08-31
Abstract: A novel dual mode, downdraft gas range provides a sealed top and sealed gas burners that can be operated effectively in a power burner mode with a downdraft exhaust and otherwise in an atmospheric mode.  In the range, a separate and independently operating air/gas supply chamber for each sealed burner is supplied with a controllable flow of gas, and, in the power burner mode, with a controlled forced flow of primary combustion air from a combustion air blower and pressure-adjustable air plenum that supply all air/gas chambers, and each air/gas supply chamber is provided with a gated opening, which is operated to provide an unobstructed flow of primary combustion air from atmosphere in non-power burner operation.  The mixture of air and primary combustion air flows from the air/gas supply chamber through a sealed conduit formed to be free of obstructions and abrupt changes in direction with a flow diffuser provided adjacent the gas burner.  In the power burner mode, the air/gas mixture is combusted without being affected by the downdraft exhaust.

Abstract: INFLATABLE CHILD VEHICLE SEAT                   ABSTRACT OF THE DISCLOSURE        A child seat device,  for use in a vehicle having a seatbelt  for  securing  the  child  seat  device  to  the  vehicle seat, has an inflatable child seat which includes an inflatable bottom panel, an inflatable back panel upstanding from the rear of the bottom panel,  and a pair of opposed,  laterally spaced inflatable sidewall panels.  Each of the sidewall panels has a back portion projecting forwardly from a respective side of the back  panel  and  a  bottom portion projecting  upwardly from a respective  side  of  the  bottom  panel.   An  inflatable  brace, disposed in each of the sidewall panels intermediate the back and bottom sidewall portions,  limits pivotal movement of the back and bottom sidewall portions towards each other.  Each of the braces defines a single interior air chamber having at most limited  gaseous  communication  with  the  bottom,  back  and sidewall panels.  Alternatively, a substantially rigid frame is secured to the back panel for movement  therewith as a unit, thereby to limit pivotal movement of the back and bottom panels towards  each other. The  frame  defines  a  pair  of  apertures configured and dimensioned to receive therethrough a seatbelt, thereby to secure the device to the vehicle seat.  A releasable harness  maintains  the  torso  of  a  child  intermediate  the sidewall panels.

Title: Detection device for selectively distinguishing from each other a number of groups of articles or animals
Inventor: ROOSENBOOM DIRK J
IPC: A01K11/00
Filed: 1993-09-21
Abstract: Title:  A detection device for selectively distinguishing from each other a number of groups of articles or animals ABSTRACT            The invention relates to a detection and weighing device for  selectively distinguishing two groups of animals, such as for instance cocks and hens, one of the groups to be distinguished being provided with a detection element, for instance a label, consisting of or provided with amorphous magnetic material. This material is recognized with the aid of an alternating magnetic field and a receiving coil suitable for that purpose, and the presence or absence of the detection element, together with the weight determined by the weighing device on which the detection system is arranged, indicates whether an animal from one group or the other group is involved, so that, for instance, the average weight of the two groups can be determined. Instead of being used in combination with a weighing device, this detection device can also be used while being coupled to other presence-detection means.          Further, the number of groups to be identified can be enlarged by using amorphous magnetic materials with distinguishable differences in magnetic properties.
Patent CA-2108973-A1 (CA)
Title: Ground cover
Inventor: JOHNSON-MARSHALL JEREMY
IPC: A63C19/12
Filed: 1992-04-29
Abstract: A ground cover (1) for protecting the grass of sports fields includes a plurality of tubes (2) joined together along seams (3) and having open ends (6) and partially closed ends (7). In use, air is pumped into the cover (1) through an inflation inlet (4) and passes into a distributing tube (5) from which it enters all the other tubes (2). The ends (6) are greater in height than the ends (7) of the tubes (2) so as to provide a slope down which rainwater may fall. With the tubes (2) inflated, a subatmospheric pressure is created beneath the cover by extracting air through an outlet (8), and the reduced air pressure draws the cover onto the ground, thus opposing wind forces which may tend to lift the cover.  Such a cover can be used without permanent securing means and is less likely to cause grass disease than conventional arrangements.
