Title: Method and apparatus for encoding data for transfer over a communication channel
Inventor: BETTS WILLIAM L
IPC: H04L25/497
Filed: 1994-05-26
Abstract: A METHOD AND APPARATUS FOR ENCODING DATA FOR TRANSFER OVER A COMMUNICATION CHANNEL          Abstract In a system that uses a dither signal d(k) in the production of a transmitted signal, the recoverability of an original trellis code is maintained while forming the dither signal using a modulo value that is equal to the distance between two adjacent symbols. This is accomplished by forming individual modulo counts (xcnt, ycnt) for each of the orthogonal components produced by the transmitter's 3-tap FIR filter (66). The modulo counts and the bits from the trellis encoder (50) are used to substitute the constellation subset identified by the trellis encoder (50) with another constellation subset. The substituted subset is used for transmission and results in recovery of the original trellis code by the trellis decoder in the receiver. (FIG. 3).
Patent CA-2126251-A1 (CA)
Title: Process of enhanced chemical bonding by electron beam radiation
Inventor: NOHR RONALD S
IPC: C08F2/54
Filed: 1994-06-20
Abstract: Permanent surface modification of polypropylene nonwoven fabrics is achieved through electron beam radiation induced chemical bonding.  The electron beam energy levels suitable for such chemical bonding are between about 5 KeV to about 110 KeV at the surface of the fabric facing the electron beam radiation source.  At these energy levels, chemical bonding,  control  of electron beam penetration and the formation of free radicals in the polypropylene nonwoven fabrics are achieved.  Control of electron beam penetration produces free radical formation and chemical bonding at selective levels within the fabric as well as bonding of different chemicals asymmetrically to the same fabric with minimal, if any, loss of polymer fabric strength.

Patent CA-2133572-A1 (CA)
Title: Engine nox reduction system
Inventor: DAVIS JAMES W
IPC: F01N3/20
Filed: 1992-04-20
Abstract: A method and apparatus are provided for reducing pollutants and especially nitrogen oxides, or NOx, in the exhaust gases of an engine. The apparatus includes a device for injecting-ammonia into a conduit that extends between cylinder exhaust valves and a catalytic converter, to mix the ammonia with the exhaust gases. Ammonia injection occurs at a location a plurality of inches downstream of the exhaust valves to avoid burning of the ammonia by flames.  The injection preferably occurs at a location where the exhaust gases are at a temperature of at least about 1200 °F to cause considerable reaction of the ammonia with NOx in the exhaust gases prior to the gases reaching the catalyst, so less NOx must be removed along the catalyst. To minimize ammonia use, it is injected only for a limited period such as a minute after a cold engine is started when the catalyst is too cold to cause signifi-cant reactions, and during operation of the engine at high power levels when the greatest amounts of NOx are produced.

Abstract: The invention relates to a spacing member for a tooth implant, comprising  a base portion (1) for attachment to a fixture (22) implanted in the jawbone, and an upper part (9) with an essentially conical limit surface for attachment  to a tooth prosthesis. The base portion comprises a through hole (5) for a spacing screw (6) which is intended to engage with an internally threaded bore (23) in the upper portion of the fixture and thereby form a first screw connection for locking the spacing member securely in a defined direction of deflection in relation to the fixture. The upper part (9) comprises a second screw connection  for attachment  of the tooth prosthesis, which screw connection forms a fixed angle .delta. in relation to the first screw connection. The upper part (14) of the inlet opening (13) for the through hole (5) which is formed in the conical limit surface in the upper part (9) of the spacing member, and through which opening the spacing screw (6) is intended to be introduced during assembly, is offset towards the line of symmetry (1a) of the through hole. In this way the height of the spacer can be kept low, even in those cases where the fixed angle .delta. between the two screw connections is comparatively small,  preferably within the range of 15 - 25°.
