Title: Method for the determination of lupus anticoagulant antibodies that cause thrombosis
Inventor: MUELLER-BERGHAUS GERT
IPC: G01N33/96
Filed: 1993-09-07
Abstract: In order to determine lupus anticoagulant (LA) antibodies in blood, plasma or tissue samples by means of the inhibitory effect of these antibodies on the neutralizing effect of protein C on the blood coagulation system, a defined amount of activated protein C is added to the sample, after incubation the remaining amount of a physiological substrate of protein C or protein S activity in the sample is determined according to known methods and the amount of LA antibodies present is calculated by comparison with a standard containing no LA antibodies. The method according to the present invention can be used to diagnose a predisposition to thrombotic events or disease-dependent risk of thrombosis as well as to monitor a therapy.

Title: Conjugated diene polymerisation
Inventor: ANSELL PETER J
IPC: C08F4/52
Filed: 1992-09-09
Abstract: A process for the polymerisation of one or more conjugated dienes by means of a rare earth based catalyst in which the ca-talyst is formed by bringing together in liquid hydrocarbon medium in the presence of a small portion of conjugated diene: a) a rare earth salt, b) an organo aluminium and c) a silicon halide or organosilicon halide and aging the catalyst before contact with the conjugated diene(s) to be polymerised. This catalyst formation procedure offers the possibility of producing a diene polymer of high cis content with a narrower molecular weight distribution and/or smaller high molecular weight fraction which is reflect ed in improved processing characteristics and reduced viscosity in styrene.
Patent CA-2117279-A1 (CA)
Inventor: VASIL JAMES F
IPC: B01D53/14
Filed: 1994-05-20
Abstract: A method and composition are disclosed for sweetening, i.e., selectively reducing the levels of H2S and organic sulfides, in gaseous hydrocarbons streams, particularly natural gas streams. A natural gas in a pipe line, at the well head, or at a common col-lection point from a number of wells, is contacted with a sweetening agent comprising the reaction product of ethylene diamine with 50% uninhibited aqueous formaldehyde. The reaction product is prepared by reacting one part 99% ethylene diamine with two parts 50% aqueous uninhibited formalin at a temperature of about 55-60°C. (higher temperatures may be used if the reaction is carried out under pressure) and is characterized by having a higher flash point, lower toxicity, and a lower freezing point, and better reaction rates, than other sweetening agents currently in use. The sweetening solution is water soluble, free from methanol or other alcohols, does not foam uncontrollably in use, and is free from water insoluble solids which would interfere with the injectability of the solution into a stream of flowing natural gas. The sweetening reaction takes place in-line without the need for a holding tank or reaction vessel. However, the treatment with the sweetening agent may also be carried out in a conventional gas treating tower. The reaction is complete and effective to completely sweeten a sour gas system.

Patent CA-2130806-A1 (CA)
Title: Semiconductor device
Inventor: IIDA MAKIO
IPC: H01L29/10
Filed: 1993-12-24
Abstract: It is an object of the present invention to provide a semiconductor device which can compatibly achieve the improvement of the withstand voltage and the integration degree. PN junction between a buried collector region 3 and a collector withstand voltage region 4 is subjected to reverse bias, and a depletion layer in the PN junction reaches a side dielectric isolation region 9a which dielectrically isolates the side of the collector withstand voltage region 4. A circumferential semiconductor region 14 which is in adjacency to the collector withstand voltage with the side dielectric isolation region 9a therebetween has an electric potential that is approximate to that at a base region 5 rather than that at the buried collector region 3.        As a result, the depletion layer is subjected to the effect of low electric potential from both the base region 5 and the circumferential semiconductor region 14. This mitigates electrostatic focusing in the vicinity of the corner parts between the sides of the base region 5 and the bottom thereof, restraining the avalanche breakdown there and improving the withstand voltage there.

Patent CA-2134949-A1 (CA)
Title: Anti-runout adaptors
Inventor: BARNES GEORGE E
IPC: B25B23/00
Filed: 1994-12-29
Abstract: During the manual assembly of any product in a manufacturing enviroment, the people who actually perform the assembly in most cases use either air or electric powered tools with various attachments ie. extensions, sockets or screw driver bits to complete their work. Over recent years through Ergonomic research, it has been found that the vibration resulting from the looseness in the connections between the tools and these attachments is causing injuries to the production personnel who are continually being exposed to this vibration. These injuries are adding a great deal of cost to the manufacturing process as a result of employee lost time incidents.   The invention I am seeking to patent is a simple nylon(UHMW) coupling type mechanism that fits snugly over the two peices being joined together. This mechanism removes the majority of sloopiness in the joint and thus the vibration that results when the tool is operated. Injuries will be reduced, tools will last longer and quality will increase.

Filed: 1995-01-16
Abstract: A method of coding a speech signal is described. In accordance with the method, a plurality of sets of indexed parameters are generated based on samples of the speech signal. Each set of indexed parameters corresponds to a waveform characterizing the speech signal at a discrete point in time. Parameters of the plurality of sets are grouped based on index value to form a first set of signals which represents the evolution of characterizing waveform shape; the signals of the first set are filtered to remove low frequency components and thereby produce a second set of signals which represents relatively high rates of evolution of characterizing waveform shape. The speech signal is then coded based on the second set of signals representing high rates of characterizing waveform shape evolution. Coding of the speech signal may further be based on a set of smoothed first signals.
