Patent CA-2131355-A1 (CA)
Title: Production of a single-gene-encoded immunoglobulin
Inventor: SHU LIMING
IPC: C12N15/62
Filed: 1994-09-01
Abstract: Construction of a single gene encoding a signal-chain immunoglobulin-like molecule is described. This single-gene approach circumvents inefficiencies inherent in delivering two genes into a mammalian cell and in the assembly of a functional immunoglobulin molecule. It also facilitates ex vivo transfection of cells for gene-therapy protocols.  The single-chain protein comprises the heavy- and light-chain variable (V H and V L) domains of a monoclonal antibody covalently joined through a short linker peptide, while the carboxyl end of a V domain is linked to the amino terminus of a human constant region such as .gamma. 1 Fc, through the hinge region. The single-chain protein assembles into a dimeric molecule of ~ 120 kDa and is secreted into the culture fluid. The single-chain immunoglobulin-like protein shows similar antigen binding affinity to that of chimeric or parental antibody and mediates ADCC. This single-gene construct approach provides a way of generating an immunoglobulin- like molecule which retains the specificity, binding properties, and cytolytic activity of a parental monoclonal antibody, and thus is a useful therapeutic and diagnostic reagent against a range of antigens, such as human carcinomas.

Title: Plastic foam material composed of a polyolefin based resin composition and method for making same
Inventor: SHIBAYAMA KOUICHI
IPC: C08L23/14
Filed: 1994-09-30
Abstract: A plastic foam material composed of a polyolefin based resin composition, consists essentially of specified amounts of polypropylene based resins and polyethylene based resins, included from about 20 to about 65 weight percent of a cross linked portion. The cross linked portion consists of from about 55 to about 95 weight percent of a cross linked polypropylene and from about to about 45 weight percent of cross linked polyethylene. The amount of cross-linkage can be determined by a xylene extraction technique. The plastic foam material may further include specified amounts of a cross-linking agent and specified amounts of an organic thermodecomposition foaming agent. The thermodecomposition foaming agent decomposes at sufficiently high temperatures to yield a plastic foam material, which exhibits superior adherence properties and fewer deformities of its surface exemplified by swelling, shrinkage and wrinkling of its surface. A method to produce the plastic foam material is also disclosed.

Title: Fluid control system for tractor trailer brake system
Inventor: CAMM JOHN JAMES
IPC: B60T17/04
Filed: 1993-06-18
Abstract: A fluid control system for use with a tractor trailer brake system comprises a branch conduit (19, 25) which is to be connected to a pressure supply line (20) and a control line (22) to enable priming of the control line (20) so that signals generated upon application of the vehicle brake pedal are more quickly transmitted to the trailer brakes to overcome problems associated with delay in application of the trailer brakes. An electrically operated solenoid valve (11) is provided for controlling fluid flow through the branch conduit so that upon application of the vehicle brake pedal the solenoid valve is operated to open the branch conduit to allow pressurised fluid to flow from the supply line (20) to the control line (22) for a predetermined time period to prime the control line (22). Pressurised fluid from the branch supply conduit is directed longitudinally down the control line (22) by a longitudinally arranged outlet (35) so that substantially all of the fluid is directed to backfill the control line. The system may be embodied in a block arrangement in which bores are drilled in a block housing and in which the branch conduit (19, 25) is formed by passages drilled in the block or may be formed from discrete hose sections and couplings.

Title: Mobile X-Ray Apparatus
Inventor: PELLEGRINO ANTHONY J
IPC: A61B6/00
Filed: 1994-11-25
Abstract: An improved mobile X-ray unit has a counterweighted articulating X-ray tube support arm that allows positioning of an attached X-ray tube virtually without the need for moving a supporting carriage. The improved mobile X-ray unit also allows the X-ray tube to be locked to the supporting carriage during travel and the articulating X-ray arm includes several electro-magnetically actuated disk brakes capable of locking articulating X-ray arm in a predetermined position. In the event that the carriage movement is required, the carriage may be moved by application of force on a force sensing handle engaged with the carriage by two strain gage assemblies. The strain gage assemblies provide signals to a motor drive control circuits which in turn propel two driven wheels in the direction and proportional to the force applied to the handle relative to the carriage.

Patent CA-2170342-A1 (CA)
Inventor: LABRUZZA GABRIEL M
IPC: E04B1/61
Filed: 1996-02-26
Abstract: A panel system is provided in which adjacent panels are removably joined at their edges. The system includes the following components: a pair of substantially identical clips, each of which is affixed to an edge of a panel, each clip including a base portion and a body portion extending upwardly from the base portion in a generally perpendicular disposition with respect to the base portion. At least two linear members extend in an inward direction away from the body portion away from the base. These members define slots which also extend parallel to thebase. The body further includes a substantially flat, outwardly facing portion on the side of the body opposite the members. Each of the panel edges defines a channelhaving flat walls which extend parallel to their respective panel. The channel walls extend from a channel bottom upwardly to the panel edge. The base of each clip is designed to be affixed to its respective channel at the bottom. The configuration and height of the clips are such that at least one of the linear members and at least one of the slots is disposed within the channel when the base is mounted in place, and at least one of the linear members and atleast one of the slots extends out of the channel beyond or above the edge of the panel. The flat, outwardly facing portion of the body of each clip extends in substantial contact with its adjacent channel wall when the clip is affixed in the channel. The clips and their associated panels can be mounted to one another by sliding the linear members of one of the clips into complementary slots in the other clips, with the channel walls preventing the two clips from being disengaged. Once it is desired to disassemble the panels they are vertically slid apart. Because the normal loading of a panel is not normally in that lengthwise direction, inadvertent dislodgement is highly unlikely.
