Patent CA-2084438-A1 (CA)
Inventor: WAGNER STEPHEN G
IPC: A63B71/12
Filed: 1992-12-03
Abstract: A shoulder pad assembly for contact sports such as hockey is described.  Two separate shoulder assemblies, in the form of generally U-shaped shoulder bands, are each pivotally connected fore and aft to chest and back pieces.  Preferably the pivotal connections are co-axial, so that there are just two pivot points, namely fore and aft pivot points centrally located on the chest and back pieces, thus generally defining a V-shape for the shoulder portions of the pad.  Preferably, the flexibility is limited by the use of a pivot clip at each pivot point, the pivot clip having at least one post disposed from the pivot axis and projecting from the clip through an arcuate slot in each shoulder band, the arcuate slots being of finite length such that further pivoting is prevented once the post reaches an end of the slot.

Abstract: A spring-applied, pressure-released parking brake is controlled by an electrohydraulic control system.  A solenoid operated parking brake control valve and a manually operated tow control valve control communication between the engine driven pump, the sump, the operator driven pump and the release chamber of the parking brake so that the parking brake can be released and applied during normal operation of the engine driven pump and so that the parking brake can be released by operation of the operator driven pump when the vehicle is shut down.  A transport sump valve and an inlet check valve operate to prevent the parking brake from engaging while the vehicle is moving too fast, as a result of operator error, hydraulic failure or electrical failure.

This permits conventional cantilever brackets to be installed through the slots and provide upper mounting portions which engage the angled walls at a point substantially spaced from the throat where greater material thickness exists.   The panels may be formed substantially thinner than prior 3/4 inch thick display wall panels.

Bandwidth utilization is optimized by pack-aging data packets into trains that are transmitted to the destination when the train is completed and upon satis-faction of other conditions. Each train undergoes data compression by execution of a suitable compression at-gorithm.

Title: Rod pump beam position determination from motor power
Inventor: LONDON ROBERT K
IPC: F04B49/06
Filed: 1994-03-22
Abstract: ROD PUMP BEAM POSITION DETERMINATION FROM MOTOR POWER  Abstract of the Disclosure An electric contactor for the motor of a reciprocating pump such as an oil well walking beam pump, and other cyclic loads, uses the power drawn by the load to determine the phase angle of the pump without the need for a separate phase signalling sensor.  The contactor couples the electric pump motor to a power line, and has a power sensor and peak detector.   The power sensor can be responsive to RMS AC power or simply to current amplitude and polarity.   The motor passes through a minimum power at the extreme top and bottom of a pump stroke, and the phase position at the top of the stroke is preferably detected by sensing for the power reversal that occurs as the momentum of the pump causes regeneration by the motor.  The contactor can have overcurrent and/or undervoltage protection features,  can include contacts for rearranging the motor windings to vary pump operation, and can report the phase to a pump control and  monitoring  system,  whereby  process  variables  are assessed as a function of phase.
