Patent CA-2179065-A1 (CA)
Title: Solid state overload relay mechanism
Inventor: EDWARDS STANLEY H JR
IPC: H01H71/64
Filed: 1995-10-13
Abstract: A solid state overload relay mechanism designed for minimizing the forces required to open an electrical contact associated therewith in the event of a current overload in a protected circuit, and further designed for overcoming residual magnetism in a solenoid initiating the opening of the contact. The contact includes a pair of stationary contacts supported by a base and a pair of movable contact supported by a contact carrier.  A latch defines a  notch which is normally engaged with a lever.  When so engaged, the contact carrier is positioned such that the movable contacts are in contact with the stationary contacts.  When the lever becomes disengaged from the latch, the contact carrier is moved and contact between the movable contacts and stationary contacts is broken.  The latch is provided with a counterbalance  weight to aid in minimizing the force required to return the latch to its original position after the mechanism is tripped.  A latch arm extends away from the latch into the path of the lever such that as the lever travels to its extent in an arcuate path, the lever imparts motion on the latch to return it to its initial position, if such has not already occured.  An auxiliary stationary contact pair is supported by an auxiliary stationary contact housing and may be selectively installed in either a normally closed or a normally open position.

Patent CA-2196407-A1 (CA)
Inventor: CHANEY JOHN WILLIAM
IPC: H04N5/00
Filed: 1995-08-04
Abstract: A smart card that includes a descrambler for descrambling entitlement information and data provides improved access control by controlling the manner in which the entitlement information portion of the data stream is passed through the smart card. Entitlement data that is descrambled and used in the smart card for functions such as key generation is re-inserted in scrambled form in the high speed output data signal from the smart card. A  variable delay device is included in the smart card for controlling when scrambled entitlement data is re-inserted into the data stream. Varying the delay permits establishing a desired timing relationship between the re-inserted data and other data in the data stream that is output from the smart card. For example, scrambled entitlement data in the output data stream can be made to exhibit substantially the same timing relationship to other data that exists in the input data stream.

Abstract: A hose connector suitable for connection either directly to a powder feed hose in a powder spray coating system or to an adapter secured to an end of a powder feed hose. The hose connector has a tubular section into which the hose end slips and forms a powder and air tight seal. A clamping sleeve is then movedon the adapter to a locking position to tighten a collet against the hose and to cause projections on the collet to engage the hose. The optional adapter has a barbed end for securing to the hose end and has a tubular end section which slides into andseals to the tubular connector section. The tubular end section of the adapter has the same outside diameter as the nominal diameter of the hose. Preferably, the hose, the adapter and the hose connector have the same inside diameters to prevent powder buildup during use. Recesses are provided on the tubular end section of the adapter for receiving the collet projections when the clamping sleeve is in the locked position. When the clamping sleeve is in an unlocked position, the projections are moved radially clear of the hose or adapter to permit easy withdrawal from the hose connector.
