Title: High temperature release films
Inventor: DEGRASSI ALFIERI
IPC: H05K3/02
Filed: 1998-02-03
Abstract: Multilayered films produced by coextending or laminating films comprised of at least one layer of polymethylpentene, at least one layer of a polyamide and an intermediate polymeric adhesive layer. The polyamide layer allows the polymethylpentene layer to be stretched up to 6 times its original length. Such a high orientation ratio for the multilayered film increases the mechanical strength and toughness properties of the film. The multilayered films are suitable for use as release films for high temperature composite applications such as printed circuit boards.

Title: Coiling temperature control method and system
Inventor: GOUDO HIDEHO
IPC: C21D11/00
Filed: 1999-12-02
Abstract: To cool a strip rolled by a hot rolling mill using cooling banks installed on the run out table at the delivery side of the hot rolling mill, and to control the strip temperature in front of coiler to a preset target temperature, the strip is conceptually divided into segments or cooling units which have a length equal to the length of a single cooling bank, the temperatures of the segments are predicted, and the cooling banks are so controlled as to have the prediction temperatures coincide with preset target temperature. In this case, a feed-forward control of the cooling water flow rate in the cooling banks are made so that predictive temperatures on a real time basis of the temperatures of the cooling segments at the time when the segments are staying in the respective cooling banks coincide with the target temperatures.

Patent CA-2293757-A1 (CA)
Inventor: HOFFMANN HEINZ W
IPC: F16D3/56
Filed: 1999-03-18
Abstract: The invention relates to a compensating coupling transmitting torque in order to compensate for imprecise alignments in machine elements that are to be joined. One disadvantage with prior art is that these couplings are relatively complicated to produce and that the service life of the spring elements used is limited. The spring element in the inventive coupling is characterised in that recesses (7, 8, 11) and threaded holes (10, 12) are provided on the periphery of the flange of the two half-couplings (1, 2) so that the radially rigid springs (9) that are used as connecting elements or other rigid spring elements inserted in the direction of the periphery fit exactly into the recesses or threaded holes in order to transmit the appropriate torque and to compensate for axial and radial alignment errors. The spring (9) that transmits torque is designed in such a way that it compensates for misalignment of shafts and transmits high amounts of torque. The spring (9) also possesses a long service life as a connecting and transmitting element.

Title: Fenestration corner lock
Inventor: GONNERMAN MICHAEL
IPC: E06B3/968
Filed: 2000-08-25
Abstract: A fenestration product such as a door or a window includes a plurality of frame members positioned in a surrounding relationship about a panel, each of the members having a pair of opposite open ends. A plurality of corner locks couple the beveled ends of the frame members together to form secure corners of the frame. A miter joint interface line is defined between the abutting, beveled ends of the members at each corner. Each comer lock comprises a generally L-shaped body having a pair of legs that are secured within the open ends of the corresponding frame members.  A pair of parallel sealant channels extend along the back, top and front of the body and are disposed on opposite sides of and laterally offset from the interface line so that sealant filling the channels creates a pair of parallel seal paths between the lock and the frame that are laterally offset from the interface line. This keeps the sealant from escaping through the interface line onto the decorative surface of the frame and creating an unsightly deposit, yet provides a secure seal against the environment. A small notch in the frame at each corner allows a small amount of the sealant to flow out of the corner and onto the non-decorative surface of the frame for covering the interface line on the non-decorative surface.
