Patent CA-2246237-A1 (CA)
Inventor: ZOLIN PAUL F
IPC: G01M99/00
Filed: 1998-08-27
Abstract: A technique and apparatus for evaluating the degree of hydroenhancement achieved in a woven fabric. The degree of hydroenhancement is related to the permeability of the woven fabric (i.e., the permeability of the woven fabric will decrease as the hydroenhancement increases). The hydroenhanced fabric is pulled over a vacuum source (while a constant vacuum is maintained) and the air flow through the fabric is measured. The air flow per unit area of fabric is then calculated and defined as the permeability. Alternatively, the permeability can be calculated by maintaining a constant air flow and measuring the vacuum drop associated with the treated fabric. The degree of hydroenhancement may then be assessed as related to this permeability measurement. The measurement may be performed on "wet" fabric immediately after it exits the hydroenhancement process and the permeability measurements used as a control signal for the hydroenhancement process (that is, to regulate the machinery used to impart the hydroenhanced quality to the fabric). Alternatively, the measurement may be performed on "dry" fabric and used, as an audit process, to assess the quality of the finished product.

Patent CA-2256962-A1 (CA)
Inventor: BRATES NANU
IPC: H01J61/34
Filed: 1998-12-23
Abstract: A starting aid for a metal halide discharge lamp. An arc discharge tube is positioned in a hermetically sealed jacket. The jacket contains a partial pressure (e.g., 400 torr nitrogen) of a gas that will aid in starting the discharge and one of the arc tube lead-ins has an electrical conductor affixed thereto and exposed to the partial pressure of the gas. An outer conductor extends on the outside of the jacket and is electrically connected to the other lead-in. When voltage is applied to the electrodes a capacitive coupling takes place between the inner conductor and the outer conductor which generates a discharge that causes a breakdown in the arc generating and sustaining medium within the arc tube and causes the lamp to start.

Title: Covering mechanism for a greenhouse
Inventor: LOONEY DONALD F
IPC: A01G9/22
Filed: 1997-09-18
Abstract: A covering mechanism for a greenhouse (10) comprises two symmetric covering panels (20) that move between the sides and the top center of the greenhouse when pulled by a cable system from a central shaft (40) at the top of the greenhouse. The panels are wrapped together around a tension spool (26) that rides on the greenhouse framing (12). One leading end (34) of the panels is attached to the side (32) of the greenhouse; the other is pulled to the top of the greenhouse by the cable system (36, 42) as the tension shaft (25) is unrolled. Tension is maintained on the covering panels both in covering and uncovering the greenhouse by the two sets of cables and tensioning springs (50) that compensate for the wrapping around the tension shaft. One of the cable sets (42), running from the covering to a central shaft (41) at the top of the greenhouse applies tension in a direction opposing that of the other set of cables (36), which runs from the covering to a driving shaft (40) on the end of the central shaft and then over a pulley (44) to a tension drum (26) on the end of the tension shaft. A motor (60) or hand crank turns the driving shaft and central shaft. Constant tension on the covering panels facilitates rainwater runoff and avoids the consequent damage due to rainwater collecting on the roof of the greenhouse.

Patent CA-2260669-A1 (CA)
Inventor: RING MICHAEL E
IPC: F16C11/06
Filed: 1999-02-04
Abstract: An improved ball and race connection assembly for use in connecting together adjacently disposed ends of railway vehicles is provided. This ball and race connection assembly is particularly useful as a connection member in slackless type drawbar assemblies. The improved ball and race connection assembly includes a race member which is formed from a polymeric and/or composite material, specifically a resin impregnated filament wound material which is wound on a polytetrafluoroethylene/polyester mesh sleeve and cured. The use of these materials enables the race member to have sufficient strength and to be self-lubricating, thus eliminating the costs of providing a lubricating material at the ball and race interface, as is necessary when using a metal race, as well as reducing the amount of friction at this interface resulting in lower L/V ratios. Also, the filament wound race member is light-weight, resulting in an overall weight reduction of the railway vehicle connection assembly, easier to manufacture than currently used metal race members, and has excellent corrosion resistance.

Title: A digital communications system having an automatically selectable transmission rate
Inventor: REY CLAUDIO G
IPC: H04W88/18
Filed: 1997-10-31
Abstract: A system and method for maintaining communication between a paging base station (13) and a mobile paging unit (14) when the signal reception is below a level that would otherwise be unacceptable. The system changes from one data transmission rate to another depending upon the quality of the communication channel. In particular, the symbol rate of the transmissions remains the same, but the number of modulation states and bits per symbol is decreased or increased depending upon the bit error rate of the received signal. In some arrangements, the transceiver (13) transmits at the highest bit rate (46) for that particular system. If no response is received from the paging unit or the paging unit sends a response signal back to the transceiver (13) indicating the signal sent is unacceptable (43), the transceiver (13) retransmits at a lower bit rate (45). In other arrangements, the receiver (14) determines the highest data rate within the group of data rates available and transmits a signal representative of that data rate to the base station (13). In response to such a signal, the base station transmits at the requested data rate until a different data rate is requested (51).

Title: Clasp for securing optical lens
Inventor: CHEONG LAK
IPC: G02C9/04
Filed: 1999-03-19
Abstract: The clip-on sunglasses assembly includes four clasps for engaging the frame of eyeglasses. Each includes a screw which secures the sunglass lens within a recess in the clasp. The end of the screw is provided with a central recess defining a circular edge. As the screw is tightened, the edge contacts the lens and forms a circular groove in the lens surface by displacing a small amount of lens material. The circular contact area distributes the stress normally concentrated at a point on the lens by a conventional screw, thereby reducing the chances of cracking the lens.      Two clasps are welded to the ends of a bridge member and affixed to pre-shaped lenses at marked locations. Each clasp has a bent tail bar enclosed by a heat shrinkable tube.
