Patent CA-2241754-A1 (CA)
Inventor: MILLER ROBIN M
IPC: F16C32/00
Filed: 1996-12-16
Abstract: A backup bearing (30) for supplying backup to magnetic bearings is provided, the backup bearing comprising: an outer race (32) disposed about the axis (Y) of a stationary shaft (17), the outer race mounted to a flywheel assembly (16) for rotational movement about the axis; an inner race (36) spaced from the outer race (32) and disposed about the axis (Y), the inner race (36) being substantially stationary with respect to the axis (Y); and a plurality of rolling elements (34) each having a central axis with each element being spaced from the inner race (36) and disposed between the inner (36) and outer race (32) for rotational movement therebetween. Rotation of the outer race (32) causes corresponding rotation of the plurality of rolling elements (34) such that upon contact of the rolling elements (34) with the inner race (36), the speed differential between the rotating rolling elements (34) and the substantially stationary inner race (36) causes each rolling element (34) contacting the inner race (36) to accelerate about its central axis with little wear on the rolling elements (34) due to skid damage because neither the inner race (36) nor the outer race (32) inertia needs to be overcome since both are always functioning at their operational speeds.

Title: Protective eyewear for industrial use
Inventor: CYR RAYMOND
IPC: G02C5/14
Filed: 1998-07-13
Abstract: The eyewear for industrial use comprises a deformable arcuate lens with a pair of temple receiving entries at opposite ends thereof, a deformable brow frame shaped to fit the upper edge of the lens so as to be engageable therewith and a pair of temple pieces, each piece being hingedly connected to a respective opposite end of the brow frame. Assembly of the temple pieces and brow frame to the lens is easily effected by inserting the temple pieces in the entries of the lens and by snap engagement of a mid-section of the brow frame to the upper edge of the lens. The assembly is made of plastic material so that it may be resiliently deformed to adapt to the various sizes of head of users.

Patent CA-2245662-A1 (CA)
Inventor: GILLIS EDWARD J
IPC: B60N2/24
Filed: 1997-12-19
Abstract: A seat weight sensor (10) incorporates a fluid filled bladder (12) placed in series with the load path in the seat (3), whereby a load applied to and distributed across the bladder (12) increases the pressure of the fluid therein. The pressure of the fluid is measured by a pressure sensor (20) and is substantially proportional to the magnitude of the applied load, and substantially inversely proportional to the supported area of the bladder (12). The output signal is substantially linear with respect to weight.  Preferably, the amount of fluid in the bladder should be less than the capacity of the bladder when the bladder is unloaded. The seat weight sensor (10) is incorporated into an accupant restraint system (7) for controlling the safety restraint system responsive to the weight of the occupant (5).

Title: Method and apparatus for forming transfer images and transfer drum used in the same
Inventor: MARUGAME TOMOYUKI
IPC: B42D15/10
Filed: 1998-09-01
Abstract: In the present invention, the thermal efficiency and concentration of a thermal head on a transfer film over the surface of a transfer drum are improved, thereby improving the reproducibility of gradation in printing, which enables highly minute transfer images to be printed on the transfer film. This makes it possible to form a highly minute image on an image-transferred member. To do this, a cushion layer made of elastomer and a rigid layer with a surface finish of less than 2.0 µm on a surface of the cushion layer are provided on a surface of the drum base of the transfer drum.

Title: Deadbolt combination locking system with automatic locking spring bolt
Inventor: MIMLITCH KENNETH H
IPC: E05B37/00
Filed: 1998-08-31
Abstract: A deadbolt lock and a deadbolt which will extend automatically whenever a container is locked by virtue of a rigid portion of the container engaging a trigger element extending from the end face of the bolt and causing the release of an outer boltportion is shown and described herein. The release of the outer bolt of the boltassembly allows the outer bolt to project outwardly and to lock the container notwithstanding the fact that the bolt has not been reset by the operator of the lock. The bolt is self-contained and can be substituted into many existing lock mechanisms of the mechanical type and into some of the existing electronic dial combinationlocks, to provide the auto-locking enhancement.

Patent CA-2251304-A1 (CA)
Title: Rotary cutter for sheet material
Inventor: DUECK RAYMOND
IPC: B26D7/12
Filed: 1998-10-19
Abstract: The rotary cutting blade is mounted on a cutting machine which dispenses and cuts sheet material. The cutting machine includes a frame for supporting a cutting table top and a dispenser for supporting a roll of floor covering material. The rotary disk shaped cutting blade is mounted on a support block the frame below the table top for movement along a slot in the cutting table. A  cable or chain driven rotary drive drives the block back and forth and at the same time provides the rotary motion to the cutting disk in a direction such that a leading edge of the disk moves upwardly relative to the floor covering material as it cuts.  The chain passes over a sprocket on the block which carries a clutch so that the clutch slips when the block reaches one end of the slot and allows the chain to continue driving the rotary blade. A rotary sharpening disk is mounted at one end of the slot and is driven by the chain so as to rotate against the blade in a sharpening action while the block remains stationary.

Title: Aa laser scan
Inventor: JAVDAN REZA
IPC: G01N21/59
Filed: 1998-11-03
Abstract: Due to the in-accessibility of the solder joints in Area Array Components (such as BGA, PBGA, CGA, CCGA, etc) the current method of solder joint verification is through the use of X-ray scanning which involves very costly equipment. The proposed device uses a novel application of laser technology for the process which reduces the cost and the duration of the verification considerably.

Title: Method and apparatus for providing a cone of silence in a cellular communication system
Inventor: WEAVER LINDSAY A JR
IPC: H04W36/14
Filed: 1997-05-22
Abstract: In a communications network, a remote unit (125) communicates with another user (30) via at least one base station (B1A). The network has a plurality of base stations (B1A-B1E) controlled by a mobile switching center (MSC-I). Each base station of the plurality of base stations (B1A-B1E) transmits an identifying pilot signal. Defining an area in which communication between a set of the base stations and the remote unit (125) is forbidden, an auxiliary antenna (130) transmits a silent region identifying pilot signal. The remote unit (125) measures a signal strength of a set of identifying pilot signals corresponding to a neighbor set of base stations (B2A-B2E) and measures a signal strength of the silent region identifying pilot signal. The remote unit (125) sends a pilot strength measurement report to the mobile switching center (MSC-I) via a first base station (B1A) with which the remote unit (125) has established communication. A handoff of the established communication between the remote unit (125) and the first base station (B1A) is initiated if the pilot strength measurement report comprises an entry corresponding to the silent region identifying pilot signal.
