Patent CA-2221061-A1 (CA)
Inventor: ZUBRISKI BRUCE ANTHONY
IPC: H01R13/639
Filed: 1998-01-22
Abstract: Over the years I have been on many construction sites and have noticed a constant problem throughout all of these sites. That is, the problem of maintaining a proper connection between power supply and power tool. Since power sources on job sites is limited, extension cords are utilized to connect power tools and equipment. Thisconnection has proven to be unreliable due to mishaps from continuous strain on lines, causing power interruptions during some often precarious situations. This in turn will often lead to user anxiety and time consumption. It is the intent of this application to ascertain a patent on a mechanical union device used to alleviate this problem and also contribute to construction site safety and ease of storage.

Filed: 1995-12-21
Abstract: A method for rapidly detecting the presence or absence of a particular nucleic acid sequence at a candidate locus in a target nucleic acid sample comprises the steps of: i) introducing a modified base which is a substrate for a DNA glycosylase into said candidate locus at one or more preselected positions; ii) excising the modified base by means of said DNA glycosylase so as to generate an abasic site; iii) cleaving phosphate linkages at abasic sites generated in step ii); and iv) analysing the cleavage products of step iii) so as to identify in said target nucleic acid sequence the presence or absence of said particular nucleic acid sequence at said candidate locus.    The method has particular application for detecting specific mutations in a DNA sample, including the detection of multiple known mutations in DNA. Large throughput of sample can be achieved rapidly and easily.

IPC: C07K16/24
Filed: 1996-10-23
Abstract: Luminal cholecystokinin-releasing factor (LCRF) is a cholecystokinin (CCK) releasing protein isolated from rat intestinal secretion. Purified LCRF was characterized by molecular weight, partial amino acid sequence and CCK releasing activity as shown in in vivo studies of anti-LCRF antibodies in blocking the CCK releasing effect of LCRF. Binding studies demonstrated localization in the duodenum, pancreas and in nerve fibers throughout the pancreas, sensory fibers and cell bodies of the nodose ganglia as well as in sympathetic nerve fibers in the adrenal medulla. LCRF appears to be a neuropeptide present in the enteric, parasympathetic and sympathetic nervous systems, but not in the brain. LCRF-IR is also present in enterocytes at the tips of small intestinal villi. Taken together, the studies indicate that LCRF is a neuropeptide that may have several functions in the gastrointestinal systems and other systems. Immunoaffinity studies using antibodies raised to synthetic LCRF1-6 and small intestinal lumen infusion studies indicate LCRF may be the CCK-releasing peptide present in intestinal secretion that mediates negative feedback regulation of pancreatic enzyme secretion and CCK release. LCRF and functionally related species have potential for development for treatment of insulin secretion, gastric and gallbladder emptying and regimens requiring appetite control or suppression.

Title: Process for making a cyclodextrin
Inventor: SKLAVOUNOS CONSTANTINE
IPC: C08B37/16
Filed: 1998-06-29
Abstract: Sulfoalkyl ether cyclodextrins are produced by a process of treating an unsubstituted cyclodextrin starting material with an alkyl sultone in the presence of a base. The base is added in a stepwise, pH controlled manner so that substantially the entire initial charge of cyclodextrin starting material is at least partially reacted. Additional base is then added to complete the reaction, and residual alkyl sultone is destroyed. The product advantageously contains low levels of both residual cyclodextrin and residual alkyl sultone.

Inventor: DELAND DANIEL L
IPC: F02M25/08
Filed: 1998-10-08
Abstract: A variable area valve and pressure regulator for providing fuel vapor purge control in an evaporative emission control system of an automotive vehicle. A solenoid valve assembly selectively controls fluid communication between a fuel vapor source and an intake manifold by varying the area of an orifice associated with the solenoid valve assembly. A pressure regulator assembly is responsive to pressure differentials between an inlet cavity and an outlet cavity to further control the flow through the purge regulator. In operation, the purge regulator assembly is operable to generate nonlinear output flow characteristics which are independent of changes in the intake manifold vacuum, as well as the inlet pressure, and which further provides the desired nonlinear response.
