Title: Optical fiber connector
Inventor: GRIFFIN MICHAEL E
IPC: G02B6/32
Filed: 1990-02-09
Abstract: Abstract An optical fiber connector can be assembled without an adhesive using a known combination of a grooved mount and a sleeve that can either grip or release a stripped end of an optical fiber.  The mount-sleeve combination is positioned within a housing which is open at one end to receive one or more stripped optical fibers and is formed at its other end with a tiny orifice that is radially aligned with a groove of the mount.  After inserting a stripped optical fiber through the mount-sleeve combination and the orifice, the sleeve is allowed to grip the fiber, thus restraining it against longitudinal movement.  Because of this restraint, the protruding portion of the fiber can be cleaved or polished along with the adjacent portions of the end cap.  The housing preferably is formed by a thermoplastic shroud and a ceramic end cap in which the orifice is formed.  The shroud preferably has an external latch by which the connector can be disconnectably fastened to a receptacle in a single motion to make low-loss connections to other optical fibers.
Patent CA-2009971-A1 (CA)
Title: Sizing apparatus and proportional spacing mechanism
Inventor: ELLIS MALCOLM P
IPC: B07B1/14
Filed: 1990-02-13
Abstract: A roller conveyor bed is formed by a plurality of driven conveyor spools or rollers rotating in the same direction for conveying and sorting objects.  The conveyor rollers define a substantially common conveyor plane along the upper surfaces of the conveyor rollers and are selectively spaced apart for selectively passing objects through the selective spaces between conveyor rollers thereby sorting the objects by a size dimension.  An anti-pinch surface is positioned adjacent to each of the conveyor rollers on the downstream side of the conveyor roller with reference to the conveying direction.  Each surface is positioned below the conveyor plane and provides an anti-pinch surface which substantially shields the downstream side of the adjacent conveyor roller where the roller surface is turning in a downward direction.  The conveyor rollers are spaced apart so that the anti-pinch surface shielding the downstream side of one conveyor roller and the upwardly turning surface of the next spaced apart roller define the selective space for passing and sorting objects.  The anti-pinch surface is an elongate stationary curved surface facing convex side upward or a second roller of substantially smaller diameter abutting the downstream side of the conveyor roller.  A proportional spacing mechanism is coupled to the spools or rollers for variable spacing of the rollers while maintaining equal spacing or proportional spacing between the rollers.

Patent CA-2017205-A1 (CA)
Title: Apparatus for particle determination in liquid metals
Inventor: HACHEY RAYNALD
IPC: G01N27/417
Filed: 1990-05-18
Abstract: ABSTRACT OF THE DISCLOSURE       In apparatus for on-line particle determination in molten metals a sample of molten metal is drawn through a calibrated passage while a steady current is established through the passage between two electrodes on opposite sides thereof. Particles moving through the passage produce voltage pulses whose magnitude and rate indicate respectively their size and number per unit volume.  The wanted test signal can be obtained between the two current carrying electrodes, or between two other electrodes disposed on opposite sides of the passage.  The electrodes form an interference-receiving antenna so that the wanted low signal/noise ratio test signal is overlaid with interference from neighbouring sources.  This interference is reduced by a cancellation signal produced by a cancellation antenna constituted by a similar pair of electrodes, either separate from the main current-carrying electrodes or having one of them in common.  A four electrode configuration permits the diameter of the passage to be monitored continuously.  A five electrode configuration has three electrodes separate from the current-carrying electrodes forming the two ante Mae and connected differentially.  A further electrode if provided is used to minimize ground loops in the signal path.  A head member carrying the tube and electrode cluster is mounted to move between operative and storage positions relative to a main body member carrying the power supply; these are made symmetrical about a longitudinal axis so that interference signals are in anti-phase and cancel.

Patent CA-2022802-A1 (CA)
Inventor: KOENCK STEVEN E
IPC: H01M50/50
Filed: 1990-08-07
Abstract: ABSTRACT OF THE DISCLOSURE         In an exemplary fast charging system, a hand-held computerized terminal with rechargeable batteries therein may have volatile memory and other components requiring load current during charging.  The system may automatically identify battery type and automatically adjust to different levels of load current.  The battery temperature may be brought into a relationship to surrounding temperature such that by applying a suitable magnitude of current to the battery for a limited time, and observing any resultant temperature increase, any overcharge condition of the battery can be determined.  For example, if the battery is found not to be in an overcharge state, a relatively high fast-charge rate may be safely applied while monitoring battery temperature.  If the battery is initially in the overcharge state or reaches such a state during fast charge, the system may automatically dynamically control the current supplied to the battery such that battery temperature is maintained generally somewhat above ambient temperature, thereby maintaining the battery in an optimum state of charge and in readiness to provide a maximum duration of portable operation.            .D86
