Patent CA-2089181-A1 (CA)
Inventor: SIMMONDS MICHAEL B
IPC: H01L39/22
Filed: 1991-06-14
Abstract: A thin film dc SQUID and its driving electronic circuitry configured with very high symmetry. The SQUID loop is formed with four holes (24, 25, 26, 27) at the respective ends of crossed slits (22, 23). Each of these holes forms a single turn secondary (24, 25, 26, 27) for symmetrically arranged pairs of modulation coils and signal coils. The geometrical placement of the modulation coil transformers with respect to the signal coil transformers results in a device which nominally has no mutual inductance between the two groups of coils when the SQUID is biased for normal operation. The external driving circuit (75-85) is configured to preserve the highly balanced nature of the chip and forces equal magnitudes of current to flow in all four of the bias leads.

Patent CA-2102509-A1 (CA)
Title: Immunostimulatory agent
Inventor: KONIG WOLFGANG
IPC: A61Q19/00
Filed: 1992-03-07
Abstract: There is disclosed an immunostimulatory agent comprising a peptide derived from lactoferrin having activity to modulate the release of inflammatory mediators from cells of the immune system. The peptide promotes the release of leukotriene B4 from polymorphonuclear neutrophils induced by activators such as the calcium ionophor A23187. It also promotes the release of histamine from mast cells induced by activators such as .alpha.-toxin-producing Staphylococcus aureus cells or the calcium ionophor A23187. The peptide is effective at low concentrations within the range of 1 to 100 ppm. By promoting the release of such inflammatory mediators the peptide can potentiate the cellular immune response and stimulate the host defense against infectious disease. This newly discovered immunostimulatory agent is useful as an active component of pharmaceuticals, hygiene products, clinical foods, etc., for prevention and treatment of bacterial, fungal, and viral infections in humans and animals.

Title: Method and system for controlling chemical reaction in a molten bath
Inventor: NAGEL CHRISTOPHER J
IPC: A62D3/32
Filed: 1992-07-06
Abstract: A method and a system is disclosed for controlling chemical reaction of a feed. The feed is directed into a reactor containing a molten bath to at least partially chemically react the feed to form an intermediate component. A portion of the intermediate component is combined with an off-gas which is emitted from the molten bath. At least a portion of the intermediate is then separated from the off-gas and returned to the molten bath. The returned intermediate component is then substantially converted to its atomic constituents. The atomic constituents subsequently exothermically react with other components of the molten bath for reaction to form compounds which are substantially stable at the operating conditions of the system, thereby allowing control of chemical reaction of the feed.

Title: Flexible sign retention and tensioning frame assembly
Inventor: HOLLOWAY GRAHAM F
IPC: G09F15/00
Filed: 1994-06-28
Abstract: A retention and tensioning frame assembly is  used to  securely and tautly mount  a  flexible sign, such as an advertisement display panel, to the side of a truck or of the semi-trailer of a tractor trailer.  The frame assembly can be used to secure any flexible sheet-like panel to a flat  surface, e.g.  a billboard.  The frame assembly comprises  a series of frame  sections which define a  slightly open  longitudinal  cylinder  adapted  to  receive therein a peripheral bead of the sign.  The frame sections   are adapted to be fixedly mounted to a side wall of the semi-trailer or the like thereby securing  the  sign  to  the  side  wall.  Each  frame section defines at an outer edge thereof opposite its cylinder an inturned lip which can be engaged by a pulling device for outwardly pulling on the sign, one side at a time, for tautly tensioning the sign. The frame sections,  once engaged to the sign,  are normally loosely attached to the side wall, and then the  sign  is  tensioned  using  the  pulling  device before the frame sections are tightly secured to the side wall with the sign being taut.
