Patent CA-2317871-A1 (CA)
Title: Method and apparatus for production of tubing
Inventor: TRIPLETT DAVID
IPC: B29C48/09
Filed: 2000-09-08
Abstract: A method and apparatus for producing an extruded product includes a machine that cooperates with an extruder. The machine is commonly used as a corrugator and the extruded product is often corrugated piping. The machine has a frame supporting a trackway in a continuous path. A plurality of mold block assemblies travel about the continuous path to form a mold tunnel along a portion of the continuous path. The mold block assemblies include a carriage connected by at least one guide and linear bearings to a pair of mold holders. The mold holders are connected to at least one pair of opposing mold blocks. Guides and directors position the mold block pairs relative to one another while the assemblies travel along the continuous path.      As the holders, and thus the mold block halves, are linearly displaceable from one another, the halves may meet to form the mold tunnel and separate to allow removal of the extruded product.

Abstract: An encrypted broadcast messaging system (102, 103) determines the management crypto-keys held by each selected subscriber (101) device and not held by each excluded subscriber device of a group. The private message is decomposed into message-parts, one message-part per an excluded subscriber device, each message-part intended to be encrypted using each management crypto-key held by the selected subscriber devices (101) and not held by the excluded subscriber device. Each message-part is encrypted using the management crypto-keys, and delivered to at least the selected subscriber devices, identifying the message-parts delivered and the message-parts necessary to re-compose the private message. Each received encrypted message-parts necessary to re-compose the private message. Each received encrypted message-part is decrypted using the intended management crypto-key, and the necessary message-parts are chosen from which the private message is re-composed by combining in the selected subscriber device (101).

Inventor: HELLMICH WOLFRAM
IPC: F02D41/24
Filed: 1998-10-20
Abstract: The invention relates to a method for electronically trimming at least one fluid injection pump. According to said method, a control module of an electronic control device detects a control signal which is corrected in accordance with the operation of the injection pump and preferably also a control signal which is corrected in accordance with the operation of the engine. Said control signal(s) is/are used to actuate the fluid injection pump. The inventive method also uses a fluid injection pump which operates according to the energy accumulation principle. The characteristic output of said fluid injection pump is identical or at least substantially approximative to a polynomial of at least the third degree. According to the inventive method, the parameters for a standard polynomial of at least the third degree are detected, stored and used to detect the required amount of fluid injection.

Title: X-configuration engine mounting
Inventor: CARLSON HOLLY MARIE
IPC: F16F7/00
Filed: 1999-04-05
Abstract: A mount for isolating a vibrating member from its support. In several embodiments an elastomeric element is made up of four components that are preferably bonded to the inclined outer surface of an inner member and the inclined inner surface of an outer member. One of the inner and outer members is bifurcated and drawing the two halves into mating engagement results in the elastomeric components being preloaded simultaneously in compression and shear. The elastomeric element is preferably formed with portions which snub movement in each of three orthogonal directions. The dimensions of the pair of elastomeric components above or below the vibrating member may be different than the other pair since the greater compression strain on one pair of components to maintain maximum design stress levels. In another embodiment, the inner and outer members are each a single component with four elastomeric elements bonded between metal plates and preloaded between the inner and outer surfaces of the members in an X-like configuration.

IPC: B65G15/30
Filed: 2001-03-08
Abstract: A modular radius conveyor belt formed of rows of belt modules pivotally interlinked by transverse pivot rods and specially adapted for following a curved conveyor path. The modules include a top, product conveying surface and a bottom, sprocket-driven surface.      The belt modules have a plurality of first link ends disposed in the direction of travel of the conveyor belt and a plurality of second link ends disposed in the opposite direction. Transverse holes in the link ends are aligned to accommodate a pivot rod. When the link ends of the consecutive rows of side by side modules are intercalated, the pivot rod serves as a hinge pin in a hinged joint between consecutive interlinked rows. To permit the belt to flex side-wise, the openings in the first link ends are slotted longitudinally in the direction of belt travel. The link ends have leg portions with differing widths. The link ends having the transverse slots are wider than the link ends having the transverse openings such that the cross-sectional areas of the leg portions are approximately equal.
