Title: Hockey glove construction
Inventor: CARDINAL GILLES
IPC: A63B71/14
Filed: 1994-11-30
Abstract: A  hockey  glove  comprising  a  hand  protective section  and  a wrist protective  section.    The  hand protective section has a palm portion, a thumb portion and finger portions interconnected by an inner fabric. An outer hand protective fabric structure is connected to  the  inner  fabric  and has  a  plurality  of  outer protective padded formations  disposed over  the hand portion, thumb portion and finger portions.  The padded formations have an outer wear resistant cover.   The padded  formation  disposed  over  each  of  the  finger portions  has  at  least  two  separated  padded  finger sections  extending  coextensively  with  each  finger portion  from  an  upper  knuckle  area  of the  finger portion  to  a  finger  ending.    A  flexible  joint  is defined at the upper knuckle area and between the two separated padded finger  sections  substantially at  a mid-knuckle  area of  the  finger  portion.    A  narrow transverse flexible protective web of wear resistant material  is  secured  in  the  joint  areas  to  provide external protection at the joint areas when the finger portions are articulated to a clasped position by a wearer clasping the hand.   The joints reduce pressure points in the hand protective section of the glove when a wearer's hand is clasped such as when gripping a hockey stick.

Title: Self-drilling hollow rivet
Inventor: SPONER WOLFGANG
IPC: F16B19/10
Filed: 1992-06-20
Abstract: A self-drilling hollow rivet (10) has a bit (11) and a rivet sleeve (12) to hold a first and a second component (16, 17) together. In order to secure the components (16 and 17) rigidly together, a rivet hole (15) is drilled by the bit(11) in a first operation. The bit (11) is given a positive and force fit in the rivet sleeve (12) by means of ribs (19', 19''). At the outer periphery of a set heat (20) there are flat surfaces with which a setting device engages. The setting device rotates the self-drilling hollow rivet. The rotary forces are uniformly trans-ferred by the self-drilling hollow rivet (12) to the bit (11) via the ribs (19, 19'') without the drill shaft's (18) breaking at the weakened point (19) during the drilling process. Once the drilling process is completed, the self-drilling hollow rivet (10) is set in a second operation in which the drill shaft (18) is pulled in the direction of the arrow (20'). Here, the claws of the serting device engage in the annular grooves (27). In this setting process the drill head (14) is pulled in-to the rivet sleeve (12) and the latter almost completely surrounds the drill head (14). The closing head is made and the hollow rivet is hermetically sealed.

Patent CA-2145264-A1 (CA)
Inventor: LANDPHAIR DONALD K
IPC: A01B73/06
Filed: 1995-03-22
Abstract: The invention is directed to a foldable agricultural implement frame having a first pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the right wing section and the center section together in a level condition, and a second pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the left wing section and the center section together in a level condition. In the first pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the right wing section and the other lifts the center section.  In the second pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the left wing section and the other lifts the center section.  A rephasing valve assembly is used to rephase the controlling/controlled hydraulic cylinder pairs when the implement frame is folded and only the center section needs to be lifted and lowered.  In rephasing the controlling and controlled hydraulic cylinders, the rephasing valve assembly couples the controlling hydraulic cylinder of the center section to the controlled hydraulic cylinder of the center section.
Patent CA-2145372-A1 (CA)
Inventor: HANSCH EGON
IPC: B65H5/12
Filed: 1995-03-23
Abstract: The conveying device exhibits a plurality of clamps which are each articulated, via a carrying arm and a linking member, on rotational elements. The pivot position of the carrying arm is controlled by a first slotted-guide path and, separately from this, the position of the linking member is controlled by a second slotted-guide path. This permits pivoting of the clamps even independently of the movement of the carrying arms. The clamps can thus be controlled in an optimum manner for the respective purpose. In particular, it is possible, with constant speed of the rotational elements, to change the speed of the clamps and, at the same time, to control the direction of the clamps independently.

Title: Relay tester
Inventor: THEE MICHAEL
IPC: G01R31/327
Filed: 1992-10-26
Abstract: A computerized relay tester (1) is provided which comprises a bar code reader (16), a test circuit (15) for determining an actual value of an operational characteristic of the relay (1), and a memory for storing reference values for the operational charac-teristic for a plurality of relays. The test circuit is operative to automatically measure the actual voltage or current at which "pick-up" or "drop away" occurs in the relay under test, by sensing an inductive voltage "spike" caused by of the relay arma-ture. Based on signals from the bar code reader, a referenoe value for the particular operational characteristic under test are retrieved from memory. The actual value is then compared with the reference value to determine whether the relay is functioning properly, and the relay tester outputs an indication of the operational state or condition of the relay.

Abstract: A semiconductor switching device for use in high voltage applications (typically ranging from 5kV up to about 50 kV) makes use of the well-known effect of reverse conduction in silicon diodes when exposed to light. Hitherto, photodiodes have been commercially available for relatively low voltage applications. The device disclosed herein is implemented by a high voltage diode (10) comprising a series of semiconductor junctions and a light emitting diode (12) operable to irradiate the junctions to render the high voltage diode conducting in the reverse bias direction, the high voltage diode and the light emitting diode being supported in fixed predetermined relation within an encapsulating material transmissive to the radiation emitted by the LED. The switching device finds application in electrostatic praying devices where the current demands are relatively small, e.g. up to about 2 µA, and is used for controlling high voltage production, distribution and/or shock suppression.

Filed: 1996-03-13
Abstract: A method for continuously precipitating a polysaccharide dissolved in an aqueous solution wherein a non-solvent for the polysaccharide is admixed with the aqueous solution to cause the polysaccharide to precipitate from the solution. The method includes the step of simultaneously feeding the aqueous solution containing the dissolved polysaccharide and the non-solvent through respective constant flow rate-pumps to produce non-pulsating metered first and second streams which are unaffected by pressure changes in the aqueous solution or the non-solvent fed to the respective pumps. The metered streams are simultaneously introduced from the respective pumps into a rotary turbine to mix the solution and the non-solvent and precipitate the polysaccharide. The precipitated polysaccharide is cut with an interlocking cutter which comprises a fixed cutter and a rotary cutter, and a suspension of finely cut polysaccharide particles is continuously withdrawn

Title: Multi-speed winch with constant mesh gearing system
Inventor: EBEY EDWARD W
IPC: B66D1/04
Filed: 1996-04-24
Abstract: A constant mesh gearing system for a multi-speed winch which allows shifting of gear ratios for varying operating properties. The gearing system incorporates at least two different sized crank gears coaxially mounted to a crankshaft.  Each of the crank gears are in constant mesh engagement with drive gears mounted to a drive shaft.   The other end of the drive shaft includes a ratchet gear drivably engaging the winch drum.  A ratchet pawl with a standoff link locks the ratchet gear against rotation in one direction. Upon cranking the standoff forces the pawl away from the ratchet gear for noiseless cranking of the winch.  The crankshaft of the winch is longitudinally shiftable to selectively engage either of the crank gears.   The shaft includes detents engageable by a spring-biased ball bearing to prevent inadvertent longitudinal movement of the crankshaft.  The crankshaft also includes a drive tooth  selectively  engageable  with  the  crank  gears.    Upon longitudinal shifting of the crankshaft, different gear ratios may be selected for operation of the winch.
