Patent CA-2065739-A1 (CA)
Inventor: LABEDZ GERALD P
IPC: H04L1/06
Filed: 1990-11-07
Abstract: A method and apparatus for diversity reception in a communication system is provided. A dual branch receiver (102, 103) is provided with a stored replica of expected reference information so that correlation with received time-dispersed signals (100, 101) produces an estimate of the transmission channel's impulse response as seen by each branch, and determines, among other things, phase error between the branch local oscillators and the time-dispersed signals. Matched filters (214, 215) are constructed which then coherently align the time-dispersed signals from each branch with that branch's local oscillator (208, 209) which con-stitutes a part of the signal equalization. A diversity processor (105) performs bit by bit selection on the re-aligned signals, maxi-mal ratio combining of the re-aligned signals, or equal gain combining of the re-aligned signals, followed by a sequence estima-tion which uses similarly selected or combined channel distortion compensation parameters to complete the equalization process on the new signal.

Filed: 1992-05-19
Abstract: A process is disclosed for separating cobalt in the form of cobalt (III) hexammine sulphate from an aqueous solution containing cobalt (III) hexammine sulphate and nickel (II) hexammine sulphate comprising adding ammonium sulphate to provide an effective amount of ammonium sulphate, ammoniating the solution with an effective amount of ammonia at a temperature whereby the triple salt of cobalt (III) hexammine sulphate. nickel (II) hexammine sulphate and ammonium sulphate is precipitated, recovering the precipitated triple salt from the solution, and repulping the triple salt with an effective amount of water or aqueous ammonia solution to selectively leach nickel (II) hexammine sulphate and ammonium sulphate to produce a crystalline cobalt (III) hexammine sulphate with a Co:Ni ratio of at least 100:1. In a preferred embodiment, the aqueous solution is produced by leaching nickel-cobalt sulphides in an ammoniacal ammonium sulphate solution under an elevated pressure of an oxygen bearing gas such as air or oxygen and at an elevated temperature with an effective ammonia to metal mole ratio to oxidize nickel and cobalt sulphides to sulphates and to produce an ammoniacal leach liquor in which dissolved cobalt is predominantly in the (III) oxidation stage.

Title: Phase Shift Sample-and-Hold Circuit for Determining the Mean Amplitude for Periodic Pulses
Inventor: WILFORD TIMOTHY W J
IPC: G11C27/02
Filed: 1992-07-15
Abstract: A phase shift sample-and-hold circuit which determines the mean amplitude of a selected portion of a periodic pulse is provided. A periodic input pulse issuccessively phase shifted by two time delays in order to provide a first phase shifted pulse and a second phase shifted pulse. The first phase shifted pulse isbuffered and applied to an integrating sample-and-hold circuit which integrates the buffered pulse during a sampling interval. The required sampling interval isgenerated by the combined operation of a comparator means and a logic means which provide a sampling command during the time interval when both the original input pulse and the second phase shifted pulse exceed a predetermined DC threshold voltage and intersect with each other. The integrated mean amplitude of the sampled portion of the first phase shifted pulse is held until the sampling of the next cycle.

Title: Spinning of high molecular weight polyethylene fiber and the resulting spun fiber
Inventor: KIRKLAND KEVIN M
IPC: D01G1/00
Filed: 1991-03-06
Abstract: A method of spinning discontinuous lengths (staple) of a high molecular weight (over 150,000) polyethylene fiber, and the resulting spun fiber, are disclosed. The method comprises blending a sufficient amount of discontinuous lengths of any other fiber (as a carrier) with the high molecular weight polyethylene fiber lengths to permit spinning. The resulting spun yarn preferably comprises about 5 to 95 weight percent discontinuous lengths of the high molecular weight polyethylene fiber which is characterized by a denier per filament of 20 or under and an ultimate elongation of 8 % or under at room temperature, and about 5 to 95 weight percent discontinuous lengths of the other fiber which is characterized by a denier per filament of 20 or under and which is either permanently crimped or has a memory. The carrier fiber or mixtures of carrier fibers may be chosen to achieve specific properties in the spun fiber: e.g., polyester or cotton for hand; pigmented polypropylene for color; aramids and polybenzimidazoles (PBI) for flame resistance; and carbon for chemical absorbance or resistance and for use in composites requiring strength and toughness. The spun fiber has utility in composites, industrial, medical and/or apparel applications.

Abstract: MESSAGE PROCESSING IN MEDICAL INSTRUMENTS Abstract of the Disclosure A defibrillator/monitor (10) is disclosed employing a message processing routine (60) that controls the way in which information from a plurality of sensing circuits (28) is communicated to an attending physician by output devices (30). In that regard, each of the various conditions monitored by the sensing circuits has a priority associated therewith. Each condition may be associated with one or moreof five different types of messages: an initial display message, steady state display message, initial sound message, steady state sound message, and display icon message. The different messages, like the different conditions, may also be prioritized. The particular message or messages produced by the output devices in response to a particular set of conditions is then dependent upon the relative prioritization of the conditions and messages as evaluated by a microcomputer (18) in accordance with the routine.

Title: Apparatus and a process for laser welding a pipe

IPC: B23K26/14
Filed: 1991-07-23
Abstract: ABSTRACT            An apparatus for laser-welding a pipe (14) along its inner periphery with a probe (1) that can be introduced into the pipe (14) contains at least one imaging element (41, 65) for focussing and deflecting a laser beam (57) that is propagated within the probe (1), essentially parallel to its longitudinal axis (10); this imaging element (41, 65) generates a laser beam (59) that is deflected and focussed onto a focal point (F) that is located outside the probe (1), and its direction of propagation is oblique to the longitudinal axis (10).  This reduces the thermal loading on the imaging elements (41, 65) that are arranged within the probe (1) and reduces the condensation of weld metal on the interior of the probe (1).

Title: High density, three-dimensional, intercoupled circuit structure
Inventor: JACOBSEN STEPHEN C
IPC: G01P15/08
Filed: 1993-04-16
Abstract: A three-dimensional circuit structure includes a plurality of elongate cylindrical substrates positioned in parallel and in contact with one another. Electrical components are formed on the surfaces of the substrates, along with electrical conductors coupled to those components. The conductors are selectively positioned on each substrate so as to contact conductors on adjacent substrates to allow for the transfer of electrical signals between substrates. The conductor patterns on the substrates may be helical, circumferential, or longitudinal, in such a fashion that substrates may be added to or removed from the bundle so that the bundle will continue to operate as needed. The cylindrical nature of the substrates leaves gaps or channels between the substrates to which cooling fluid may be supplied for cooling the circuitry.

Title: Pneumatic water vaporizing system
Inventor: KEATE PETER B L
IPC: B01D53/26
Filed: 1993-04-23
Abstract: B) ABSTRACT Existing methods used to remove water from compressed air are well known. These systems incorporate containers to trap the moisture removed, these traps require constant attention to remove the water taken from the air processed. The disadvantages of these methods is the need for the equipment, due to the size, weight, the noise they produce, and the need to drain the water removed, to be located at a distance from the tool to be run by compressed air. When air, under compression, travels through a tube moisture is automatically generated and the further the compressor or the drier is from the equipment to be powered the more moisture is generated. The device which is small and light is designed to be located on or immediately alongside the item of equipment to be powered. This proximity results in the elimination of moisture generated in the pressure tubing when it arrives at the item to be powered by air.     The unit which can be as small as 4"x1" incorporates a system which increases the speed of the air passing through and vapourizes any remaining moisture contained in the air lines.
