Patent CA-2089196-C (CA)
Title: Cushioned stop for powered conveyor
Inventor: KETTELSON RUSSELL W
IPC: B23Q16/00
Filed: 1993-02-10
Granted: 2004-11-09
Abstract: A stop mechanism mountable on a powered conveyor, such as a conveyor having continuously-driven drive rollers which support and drivingly move loads such as pallets. The stop mechanism is mounted directly under and between sidewardly-spaced drive rollers to permit use of through shafts between sidewardly-spaced pairs of drive rollers. The stop mechanism has a vertically-oriented stop lever which projects upwardly for contacting a moving load, which contact effects limited vertical swinging of the lever into engagement with a fixed stop. The lever is coupled to a hydraulic shock absorber which effects rapid deceleration of the load to cause cushioned contact thereof with the fixed stop.      The shock absorber preferably has an internal orifice arrangement associated with a pressure chamber which results in the orifice flow area progressively decreasing as the stop lever is moved by the load to provide more optimum control over liquid pressure and control over the resistance force imposed against the load. The stop lever is movable downwardly to disengage the load, and is spring urged upwardly to permit engagement with the next load.

Title: Connection path selection method for cross-connect communications networks
Inventor: BOWDON EDWARD K
IPC: H04L12/56
Filed: 1993-05-13
Granted: 2001-07-17
Abstract: A method and system for finding a path through a communications matrix represents the assignment of a center stage switch through an input switch to input gates by an input stage array, center stage switch connections between an input stage switch and an output stage switch by a center stage array, and output stage switch connections to output gates by an output stage array, as well as representing idle input switch links to the center stage switches by an idle input array and idle output switch links from the center stage switches by an idle output array. The method and system perform a process of pumping the input stage array, output stage array and center stage array using information in the idle input link array and the idle output link array to determine an optimal center stage switch having both an idle input link between a predetermined input gate and the optimal center stage and an idle output link from the optimal center stage to a predetermined output gate as identified by the idle input link and idle output link arrays. The pumping process relies on the idle input array and idle output array for connection status data. The method and system may be used advantageously with a rearrangeable communications matrix to establish optimal connection configurations during both normal and rearrangement operations.

Abstract: A diaphragm valve is disclosed in which a diaphragm is movable to engage or disengage from a valve seat in a replaceable seat ring to restrict or permit fluid flow.  The seat ring includes a valve hole for communicating with a valve flow-in passage mouth and a communication hole for communicating with a valve flow-out passage mouth.  The annular valve seat is provided projecting from the surface of the seat ring, formed along the peripheral edge of the valve hole.  On a back side face of the seat ring spaced from the diaphragm, a seal part is formed projecting along the peripheral edge of the valve hole and a ring contact part is formed projecting along the peripheral edge of the valve ring.  The projection of the seal part from the ring back side is set slightly larger than that of the ring contact part such that when the ring contact part is brought into contact with a bottom wall of the valve under compressional forces, the valve ring is bent elastically, and hence the contact surface pressure of the seat part to the valve bottom is increased.  The increased contact surface pressure preventing fluid from leaking out between the flow-in passage mouth opening in the bottom surface of the valve and the seat ring.

Abstract: The present invention relates to an improved method for multilateral completion and cementing (e.g. sealing) the juncture between primary and lateral wellbores. The completion method of the present invention addresses the issue of cementation and sealing of junctures between vertical and lateral wellbores. It is desirable to have the ability to re-enter each lateral wellbore as well as maintain the option to perform any function that could be done in a single wellbore. For this reason, cemented and sealed lateral wellbores are desirable so that normal isolation, stimulation or any other operation can be achieved. The method allows sealing and reworking of either wellbores with single laterals or multiple laterals and provides safe durable junctions therebetween. The method of this invention utilizes a "hook" liner hanger system.

Title: Apparatus and method for enhancing the security of negotiable documents
Inventor: SANDRU CALIN A
IPC: G07D7/0047
Filed: 1996-03-01
Granted: 2006-11-21
Abstract: The invention relates to an apparatus and method for enhancing the security of selected information associated with a negotiable document, such as the monetary value of a cheque. In the invention, one or more security features are printed or applied onto the cheque. One such security feature is an encrypted control code. The preferred embodiment employs a secret key cryptographic scheme to encrypt the monetary value and thereby generate a first control code which is printed on the cheque. When the cheque is presented for payment, a validator, such as bank or cheque clearing house, employs a verification system having a copy of the encryption key to read the monetary value from the cheque and re-encrypt it according to said scheme to generate a second control code. The cheque is not honoured if the first and second control codes are not identical. Another security feature is a security image, composed, for instance, from a foreground image of the monetary value superimposed over a background motif image. The security image has a number of hidden attributes, such as the relative aspect ratios, absolute and relative dimensions of the underlying foreground and background images, that are preselected and used when printing the security image. When the cheque is presented for payment a teller can visually inspect the security image for compliance with certain of the preselected attributes. The preferred validation system can also electronically scan the security image for the hidden attributes. This comparison makes it difficult for a forger to copy, for instance, the monetary value of the cheque and add a significant digit to it because some of the foregoing preselected image attributes are liable to change and be detected. The composite image serves as a back-up security when verification of the encrypted control code is not possible.
