Patent CA-2065739-C (CA)
Title: Method and apparatus for diversity reception of time-dispersed signals
Inventor: LABEDZ GERALD P
IPC: H04L1/06
Filed: 1990-11-07
Granted: 1996-09-24
Abstract: A method and apparatus for diversity reception in a communication system is provided. A dual branch receiver (102, 103) is provided with a stored replica of expected reference information so that correlation with received time-dispersed signals (100, 101) produces an estimate of the transmission channel's impulse response as seen by each branch, and determines, among other things, phase error between the branch local oscillators and the time-dispersed signals. Matched filters (214, 215) are constructed which then coherently align the time-dispersed signals from each branch with that branch's local oscillator (208, 209) which con-stitutes a part of the signal equalization. A diversity processor (105) performs bit by bit selection on the re-aligned signals, maxi-mal ratio combining of the re-aligned signals, or equal gain combining of the re-aligned signals, followed by a sequence estima-tion which uses similarly selected or combined channel distortion compensation parameters to complete the equalization process on the new signal.
Patent CA-2073350-C (CA)
Title: Ribonuclease dimers and method of preparing them
Inventor: HERRMANN PETER
IPC: C12N9/22
Filed: 1990-01-08
Granted: 2001-03-27
Abstract: A method for preparing purified ribonuclease dimers is provided which comprise the steps of dimerizing monomeric ribonuclease with a suberimidate coupling reagent, filtering out undimerized monomers and oligomers from the dimer solution using a series of ion exchange resin chromatography steps, monitoring the progress of the reaction through gel electrophoresis, and collecting the purified ribonuclease dimer product.  The method is advantageous in that large amounts of the dimeric product can be obtained efficiently and relatively inexpensively, and the ribonuclease dimers so produced can be employed for their beneficial effects in combatting viral and bacterial infections without the cytoxic effects normally associated with the ribonuclease monomer.

Patent CA-2082977-C (CA)
Title: Injection molding machine
Inventor: HEHL KARL
IPC: B29C45/50
Filed: 1992-11-16
Granted: 2003-09-09
Abstract: An injection molding machine comprises a carrier block, which contains a plasticizing cylinder and to which hydraulic advance-retract cylinders and hydraulic injecting cylinders are axially coupled. The cylinder barrel of each advance-retract cylinder carries an injecting piston for cooperating with an injecting cylinder barrel which surrounds the advance-retract cylinder barrel. Because each advance-retract cylinder barrel is integrally formed with a radial flange, which constitutes the injecting piston for cooperating with the associated injecting cylinder barrel, the injecting unit will be able to withstand high pressures and its parts can yet economically be made in series.

Title: Communicating messages between processors and a coupling facility
Inventor: ELKO DAVID A
IPC: G06F15/17
Filed: 1993-01-05
Granted: 1997-04-08
Abstract: A mechanism for communicating messages, each including a command and  a  response,  in  a  network  having  central processing  complexes  (CPCs)  and  one  or  more  coupling facilities.  Each coupling facility has a central processor for executing instructions and a main storage.  Messages are sent from a message control block in the main storage of the CPC sending the message, and the response to the message is received in a message response block of the CPC without an interrupt  to  the program being  executed by  the  central processor of  the CPC.   Each message  from  a CPC  to  the coupling facility may include a command and an indicator bit which instructs the coupling facility to execute the command either  in  synchronism  with  or  asynchronously  to  the execution of the sending processor.  The coupling facility executes  the  command  and  returns  a  response  which  is received in a message response block of the main storage of the sending CPC without an interrupt to any program being executed by the central processor of that CPC.

Title: Error detection system
Inventor: GOULD ADAM F
IPC: H04L1/00
Filed: 1993-03-11
Granted: 1999-02-23
Abstract: An error detection system for discrete receiver. The error detection system indi cates bad frames of binary information signal which contain distorted bits in excessive numbers so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder (512) is re-encoded by an encoder (524), and the re-encoded signal (530) is compared with the signal received (506) by the receiver. When excessive numbers of re-encoded signal portions differ too greatly with corresponding portions of an actual, received signal, a bad frame i ndication is generated (590).

Granted: 1998-09-22
Abstract: Trousse et méthode d'analyse pour la détection multiple, rapide et sensible, de pesticides à base d'organophosphates et de carbamates.  La méthode fait appel à une préparation de cerveau d'insecte comportant un mélange de récepteurs d'enzymes, avec des sites qui interagissent avec ces pesticides.  Les pesticides modifient ou entraînent une réduction significative des activités de la préparation de cerveau, qui sont régies par une corrélation inverse avec la quantité de pesticide présente dans l'échantillon.  L'activité est mesurée à l'aide d'analogues ou de substrats traceurs qui, après exposition de la préparation de cerveau, sont modifiés; les changements sont mesurés par une réaction photoémissive.  Dans l'une des versions de l'invention, comme dans le cas de l'acétyl-luciférine, on a constaté que l'hydrolyse d'un dérivé de la luciférine en D-luciférine par une préparation de cerveau d'insecte s'est révélée extrêmement sensible pour les organophosphates et les carbamates.  La luciférine libérée par la réaction est oxydée par l'enzyme luciférase et l'adénosine-triphosphate (ATP), un donneur d'énergie, et émet de la lumière mesurée par bioluminescence ou chimioluminescence.
