Title: Removing lipids from foodstuffs
Inventor: MCLACHLAN CORRAN N S
IPC: A23L5/20
Filed: 1989-12-14
Abstract: ABSTRACT   A process for the removal of sterols and/or lipid components (eg, cholesterol and fats) from lipid containing food (eg, meat) using sub or super-critical fluids (eg, CO2) in-volves initial processing of the food to produce an intermediate moisture product in which substantially all of the "free water" but not all of the "bound water" is removed. Different moisture removal techniques may be used. Where freeze drying of food flakes is adopted the moisture level is preferably reduced to 30-55% w/w. The intermediate moisture product is treated with supercritical CO2 to remove the lipids therefrom. Optionally the cholesterol can be separated from the fat component by use of an adsorb-ent to selectively remove the cholesterol from the supercritical CO2. The product can be reconstituted with water and fat to provide a reconstituted meat product suitable for hamburgers.

Patent CA-2010366-A1 (CA)
Inventor: RIOUX JEAN-PIERRE
IPC: A47C27/08
Filed: 1990-02-19
Abstract: A seat made of a plurality of adjacently positioned cushions  is characterized  by  each cushions having an envelope made  of  a  gas-tight elastic material.  Each envelope has a predetermined shape under a maximum gas pressure causing no elastic extension of the material.   The  envelope contains  a reduced internal gas pressure slightly less than  the  maximum gas pressure to allow the sagging of the predetermined shape.  The reduced gas  pressure  is  sufficient to prevent opposite walls  of  the  seat  to collapse  one against the other upon external pressure of a portion  of  a human  body.   The  material forming the envelope of the  cushion  has  an elasticity  sufficient  to stretch and to conform to the contour  of  said portion of the human body.

IPC: G06K7/10
Filed: 1990-12-07
Abstract: A symbol reader for reading symbols on a symbol surface.  An optical system including a laser, condensing lens and a scanning mirror illuminate a symbol surface to be read with a laser beam, scanning across the symbol surface.  A transducer measures the amount of light reflected from the symbol surface.  A differential circuit develops a differential coefficient indicative of the change of light intensity as light scans the symbols being read.  A control system adjusts the optical system illuminating the symbol surface so as to maximize the differential coefficient, thereby minimizing the diameter of the light beam to allow for adequate reading at variable distances.

Title: Method of adapting a mobile radio communication system to traffic and performance requirements
Inventor: OSTLUND ANDERS K
IPC: H04B7/26
Filed: 1990-08-24
Abstract: A method in a mobile radio communication system for adapting the system and communication to prevailing traffic and performance requirements. According,to the invention a mobile station inserts information on particular nodes in its messages transmitted to a base station in response to an invitation message from the base station. The codes indicate whether a message is new or retrans-mitted and/or message age. The base station receives radio signals in time slots identified in its invitation message and estimates for each time slot based on radio signals received in the time slot whether the time slot is empty ar busy, or whether the time slot is empty or correct. For each message received and understood the base station retrieves the code. The retrieved codes and the number of emty/busy/correct slots enable the base station to estimate prevailing system traffic and performance.      Estimations on prevailing traffic and performance are used to control system parameters such as number of time slots following an invitation message.
Patent CA-2042402-A1 (CA)
Inventor: FITE FRANKLIN D JR
IPC: H04L12/56
Filed: 1990-11-02
Abstract: A transmission is disclosed for recovering from faults in transmission equipment or facilities forming so-called virtual circuits for transmitting packets in a network. Faults are detected in transmission paths associated with a network node and an individual fault indication message is generated for each network facility that has at least one virtual circuit affected by the fault. Each fault indication message includes the identity of each virtual circuit on the associated network facility affected by the fault. The message is transmitted in-band on at least one of the affected virtual circuits on the associated network facility. If affected virtual circuits are terminated in the node, they are switched to alternate virtual circuits. Otherwise, the fault indication messages are transmitted over the identified facilities to other unknown nodes. A node receiving a fault indication message determines which virtual circuits identified in the message are terminated in the node and which virtual circuits pass through the node. The virtual circuits that are terminated in the node are switched to alternate virtual circuits. For virtual circuits passing through the node, the network facilities associated with them are identified and a new fault indication message is generated for each of the identified facilities. Each of the generated fault indication messages is transmitted in-band on at least one virtual circuit on the, respective, identified network facility. (FIG. 2)
