Patent CA-2162389-A1 (CA)
Title: Cleats
Inventor: LYON ROBERT CYRIL
IPC: F16L3/10
Filed: 1994-05-13
Abstract: A cleat for mounting a cable has a hook-shaped body (3) with an open cable-receiving mouth. With the cable in position the mouth of the hook shaped body is closed with a closure part (4). The inner surfaces (12, 28) of the body (3) and the closure part (4) define a ring with multiple inclined or curved portions (14, 15, 16,, 30, 31, 32) so that cables of different diameters can be clamped between the body (3) and closure part (4). The open mouth of the body (3) may face upwardly to retain the cable prior to attachment of the closure part (4).  Clips (39, 40) may be provided around the cleat to provide fall-back support for the cable in high temperature or fire conditions.
Patent CA-2164174-A1 (CA)
Inventor: HEEGARD CHRIS
IPC: H04L27/36
Filed: 1995-11-30
Abstract: A rotationally invariant trellis coder is provided for encoding data to be transmitted using a two-dimensional symbol modulation.  A precoder, provided at the transmitter, processes data such that a counterpart postcoder at the receiver will provide an output that is invariant to any multiple of a 90° rotation.  An encoder encodes the precoded data using a transparent binary convolutional code, which can be a punctured or unpunctured code.  The encoded data is mapped to a two-dimensional signal space having a plurality of signal points.  The signal points are labeled with unique binary codes in which the two least significant bits, denoted by (Ij, Qj), are permuted and partially complemented to (?j, Ij) for each 90° phase rotation around the signal space.  The remaining most significant bits for each point, if any, are invariant to such rotation.  The postcoder provided at the receiver inverts the precoder and is feedback-free, thus limiting error propagation.

Title: Sound source data generating method, recording medium, and sound source data processing device
Inventor: FURUHASHI MAKOTO
IPC: G11B20/00
Filed: 1995-12-01
Abstract: Sound source data is constituted by a 14-byte sound data area SA consisting of 28 samples of 4-bit adaptive differential PCM data and a sound parameter area PA consisting of loop information LP, filter information FL and a shift amount RA.    In encoding the sound source data, a CD-ROM XA encoder may be employed. 4-bit ADPCM data is decoded by a BRR decoder 53, pitch-converted by a pitch conversion unit 54, and then processed with envelope transform by an envelope generator 58.  After that, sound outputs of left and right channels outputted with the sound volume adjusted by volumes 60L, 60R, and 16-bit PCM data with the sound volume adjusted by a mixing volume 65, are added by an adder 62.  Further, the sound data from the mixing volume 65, or an addition output produced by adding the sound data from the mixing volume 65 with the sound data from the volumes 60L, 60R, is reverberated by a reverberation processor 68.  The sound data with the sound volume adjusted by a reverberation volume 69 and the sound data from the adder 62 are added.    The sound source data and the real sound data can be easily mixed in a single circuit.
