Patent CA-2066200-A1 (CA)
IPC: B29B11/16
Filed: 1990-09-27
Abstract: 2066200 9104840 PCTABS00003 An apparatus for manufacturing fiber preforms is described, in which a relatively small motor (36) is able to power a large fan (34) because the fan is kept in a partial vacum condition. A duct (30) connects a fan housing to a vacuum box (24) which has an air flow opening (26) therein of relatively narrow width. A shuttle member (28) is horizontally translatable above the vacuum box (24) on a support bed and the shuttle member is divided into air flow chambers by baffle plates (44). Only a smaller number of air flow chambers can pass above the air flow opening at a single time and this serves to keep low pressure in the vacuum box. In addition, a vortex gate (75) is provided in the duct between the fan housing and the vacuum box and serves to restrict air flow through the duct when the pressure within the duct drops below a certain level.

Patent CA-2072866-A1 (CA)
Inventor: SAMUEL JOHN
IPC: G01N33/574
Filed: 1990-11-01
Abstract: A heterologous sandwich immunoassay has been developed for human TF antigen using a monoclonal antibody as the catcher and labelled peanut agglutinin as the probe. Since human TF antigen is shed by tumor cells, a positive determination of the TF antigen in a patient sample indicates the presence of cancer. The test can also be used to monitor the course of conventional chemotherapy or radiotherapy by monitoring the amount of TF antigen in a fluid sample from a patient being so treated. Because of the sensitivity of the assay method, cancer can be detected in very early stages by the assay method of the present invention.

Title: Step-dimming magnetic regulator for discharge lamps
Inventor: NUCKOLLS JOE A
IPC: H05B41/40
Filed: 1992-08-27
Abstract: A dimming system for a discharge lamp has a magnetic regulator with first, second and third windings linked by a magnetic core, the first winding being connectable to a source of alternating current. The second winding and a starting circuit are connected to the lamp for lighting the lamp. The third winding is tapped and has a ballast capacitor connected across the winding. An inductive reactor and relay contact set are connected in series between one end of the third winding and the tap so that when the contact set closes, the reactor stores energy from the source and reduces the power to the lamp, abruptly reducing its light output. A motion-responsive detector is used to energize the relay. With a normally closed contact set, the lamp is dimmed until a moving person is detected, opening the contact set and increasing the lamp light output. Multiple lamps can be controlled simultaneously.

Title: Method and apparatus for sharing a telecommunications channel among multiple users
Inventor: DUAULT MAURICE
IPC: H04Q11/04
Filed: 1993-04-06
Abstract: A method and an apparatus allows multiple users to share one or more data communication lines without requiring the users to actively participate in the arbitration.  The preferred embodiment comprises an ISDN Port Connection Manager (PCM) for managing the use of each of the individual channels of one or more line ports having ISDN service thereon.  The ISDN PCM manages the use of the channels between applications using such distinct access methods as the IBM Virtual Telecommunications Access Method (VTAM), TCP/IP, and Open Systems Interconnect (OSI) access methods. The ISDN PCM determines that an application needs access to an ISDN channel, determines the availability of the ISDN network and sets up the communication between the application and the network if the channel is available. If no channel is available at that time, the ISDN PCM indicates to the application when the channel becomes available so that the application may determine whether it still needs access.

Title: Food package comprised of polymer with thermally responsive permeability
Inventor: STEWART RAY F
IPC: C05G3/00
Filed: 1991-12-06
Abstract: Food may be packaged and preserved for extended periods using intelligent polymers formed into food containers which have specific and variable gas permeabilities. The polymers used in forming the food packages are intelligent in that they have permeabilities which may be radically and reversibly changed by relatively small changes in temperature. By using different types and formulations of polymers and various temperatures, it is possible to create an environment within the food package which adjusts to the respiration of the food so as to best preserve the color, quality and/or shelf life of the food. The polymers are side-chain crystallisable polymers designed and formulated so as to provide a material which is substantially impermeable to a gas such as oxygen, carbon dioxide or water vapor at a temperature below a give phase transition point and permeable to the same gas at a temperature above that point.

Abstract: Abstract of the Disclosure There   is   disclosed   a  method   for dimensionally   stabilizing   a   nonwoven   web   of thermoplastic bicomponent  fibers to a low Poisson ratio.   The process includes laying a web of the fibers on a carrier, subjecting the web of fibers to a  source  of  heat,  consolidating  the  web  to  a predetermined thickness by drawing the web through a caliper roll  with a predetermined  fixed gap,  and cooling the web to set the web at the predetermined thickness.   There is also disclosed a machine for dimensionally   stabilizing   a   nonwoven   web   of thermoplastic bicomponent fibers to a  low Poisson ratio.   The machine includes a fiber forming head which first deposits thermoplastic bicomponent fibers onto a moving carrier to form a nonwoven web.   The carrier moves the web downstream to a through-air bonder in which the web is subjected to heated air of sufficient temperature to soften the outer surface of the fibers.  A caliper roll is located at the exit of the  through-air bonder.   The  caliper  roll  has  a predetermined fixed gap through which the heated web passes.  A cooling zone is located downstream of the caliper roll in which cooling zone the nonwoven web is then subjected to cooling air in order to set the web at a predetermined thickness.
