Title: Synergistic compositions
Inventor: WU TAI-WING
IPC: A23D9/06
Filed: 1992-07-08
Abstract: ABSTRACT           A cytoprotective  composition  for protecting against oxyradical damage caused by ischemia - reperfusion injury to body organs and tissues, and a food and non-edible  oil  preserving  composition,  is provided. The composition includes a gallate compound and trolox, which is  a  hydrophilic  analogue  of  .alpha.-tocopherol.  The two ingredients act together synergistically to provide a composition administrable to a patient's blood, effectively to protect cells,  organs and tissue  from free radical damage, or which can be incorporated in foods to retard the onset of rancidity.   It is also useful in retarding the decay of non-edible oils such as fuel oils.

Patent CA-2086763-A1 (CA)
Inventor: TAKEI YOSHITSUGU
IPC: A61P31/04
Filed: 1992-05-11
Abstract: A sewing machine needle is manufactured without producing any burrs on a blade by subjecting the whole blade to die pressing.  A needle blank (10) is subject to double swaging, resulting in it being formed with blade sections (14, 16). Then, the needle blank is formed with an elongated portion (22) for subsequently forming a clearance-above-eye above a needle eye. The die pressing permits both side surfaces of a long groove (28) to be spread so as to be spaced from each other at a predetermined angle, and permits the clearance-above-eye (40) and eye portion (30) to be formed. The sewing machine needle thus formed exhibits sufficient rigidity and proves an increased space between the blade and a sewing thread, resulting in a sewing operation being carried out stably and at an increased speed.

Patent CA-2098853-A1 (CA)
Inventor: GORNEY ROBERT E
IPC: H04B1/707
Filed: 1993-06-21
Abstract: Digital information is convolved with a pseudorandom code and then transmitted at radio frequency in a spread spectrum signal to a receiver also containing the same pseudorandom code. Since the transmitted signal is below the noise floor for that bandwidth, it is virtually unjammable and undetectable without possession of the pseudorandom code. Successful extraction of the transmitted information depends upon precise matching of the transmitted frequency and the exact phase matching of the pseudorandom code at the receiver with the convolved pseudorandom code in the transmitted signal.
Patent CA-2099574-A1 (CA)
Inventor: HODJAT HOSSEIN K
IPC: B01J20/281
Filed: 1991-12-31
Abstract: A method of derivatizing a chromatography matrix having a hydrophobic surface. The technique involves reacting the hydrophobic surface with a halosulfonating agent to produce a significant amount of halosulfone groups covalently bonded onto the surface.  Sulfonamide bonds are then formed between these halosulfone groups and a group of functions on a polyaminated polymer to produce a pellicular anion exchange layer covalently bonded to the surface. The resulting layer is stable in the absence of cross-links between the molecules of the polyaminated polymer.

Title: Method to manufacture multiple part imaged documents
Inventor: DOANE IVAN G
IPC: B41F17/02
Filed: 1993-08-18
Abstract: Multiple part documents in which each part has common non-variable information and variable information are produced at high speed with a minimum amount of equipment. Utilizing either sequential press technology or large diameter plates, the multiple parts of the document are sequentially printed on a single web with the non-variable information. The variable information is sequentially printed on the same web in a procedure distinct from the printing of the non-variable information, typically utilizing a single ion deposition printer for each face of the web. The parts are separated and intelligently gathered and then the parts are sealed together to form a document, along one edge, by applying glue, or pressure seal adhesive. After sealing the documents may be rotated and delivered to a carrier web.      Alternatively, an outer wrapper or envelope, variably imaged by another ion deposition print engine, may be provided around the multiple part document's after sealing.
