Title: Thermoplastic resin coated aluminum alloy sheet, and method and apparatus for production thereof
Inventor: KOMAI MASAO
IPC: B32B15/08
Filed: 1997-03-24
Abstract: A thermoplastic resin coated aluminum alloy sheet has excellent processing adhesion and high adhesion after retort processing such that laminated thermoplastic resin layers do not peel off even when the alloy sheet is subjected to severe processing such as stretching after deep drawing and furthermore, ironing. A production method and a production apparatus for the alloy sheet are also described. A treatment by an alkaline solution and a treatment by an acidic solution are sequentially applied to bring the surface of an aluminum alloy sheet into a specific surface state and then electrolytic chromic acid treatment is carried out by a known method so as to laminate a thermoplastic resin to an aluminum alloy sheet having a two-layered film which comprises metallic chromium as the lower layer and a chromium hydrate as the upper layer and has a specific surface condition. As a result, a thermo-plastic resin coated aluminum alloy sheet having excellent processing adhesion capable of withstanding molding and processing can be obtained.

Title: An adaptive decoding system for processing encrypted and non-encrypted video data
Inventor: BRIDGEWATER KEVIN ELLIOTT
IPC: H04N7/167
Filed: 1997-05-22
Abstract: An adaptive decoder (25) generates a program representative datastream in selectable, encrypted or decrypted form. A method for adaptively processing input encrypted program data with an associated encryption code provides (110, 115) either an encrypted or a decrypted program output. In an encrypted mode, encrypted program data (47) and an associated encryption code is exported to an output port. In a decrypted mode, input encrypted program data is decrypted (50) using an encryption key derived from the encryption code to provide decrypted program data. The decrypted program data is exported to the output port. Non-encrypted program data is exported to an output port (95) in a selectable non-encrypted mode.

Patent CA-2258657-A1 (CA)
Title: Suction and irrigation handpiece and tip
Inventor: SAKAL ROBERT
IPC: A61M1/00
Filed: 1997-04-07
Abstract: A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.
Patent CA-2260222-A1 (CA)
Title: Coding and decoding of audio signals by using intensity stereo and prediction
Inventor: GBUR UWE
IPC: H04B1/66
Filed: 1997-06-03
Abstract: In the coding and decoding of stereo audio spectral values both the intensity stereo process and prediction are used in order to achieve high data compression. If intensity stereo coding is active in one section of scale factor bands, the prediction for the right channel in that range is deactivated, whereby the results of the prediction are not used to form the coded stereo audio spectral values. To allow further adaptation of the prediction for the right channel, the predictor of the right channel is fed with stereo audio spectral values for the channel, which again are intensity stereo decoded.
