Patent CA-2055105-A1 (CA)
IPC: H04B1/707
Filed: 1991-11-07
Abstract: A receiver for pseudorandom noise (PRN) encoded signals consisting of a sampling circuit and multiple channel circuits, with each channel circuit including a carrier and code synchronizing circuit and multiple digital correlators with dynamically adjustable code delay spacing.   The sampling circuit provides high-rate digital samples of the incoming composite signal to each receiver channel.  Within each channel, the synchronizing circuit detects cycle slips in a locally generated carrier reference signal as well as phase drift in a locally generated PRN code signal.  The correlators compare the digital samples with a locally generated PRN code to produce early, late, and/or punctual correlation signals which are used to adjust the local PRN code.  A non-linear sampling technique may be used to provide increased sensitivity in the presence of continuous wave interfering signals.

Title: Adaptable card mounting system
Inventor: CANTRELL GREGORY A
IPC: H05K7/14
Filed: 1992-03-31
Abstract: ABSTRACT      An adaptable card mounting system includes a number of card guides having predefined configurations selectively mounted at slot locations within a chassis to enable cards of varying dimensions to be installed.  A first type of card guide is mounted to opposed walls of the chassis at each slot location.  This first card guide is required for installation of cards of a first length and first depth.          A second card guide is mounted to the walls of the chassis in conjunction with the first card guide at slot locations requiring installation of circuit cards having a second depth different than that of the first depth.  A third type of card guide is mounted between the opposed first or second card guides at selected slot locations requiring installation of cards of a second length shorter than the first length.  Use of the three card guides at selected slot locations permits installation of circuit cards of varying dimensions independent of slot location.   The chassis is therefore adaptable to modifications in the circuit design on the supported cards that require changing the number or shape of the included cards.       GW04:61483

Inventor: KELLER ROBERT C
IPC: B32B25/04
Filed: 1990-08-31
Abstract: The present invention provides for an improved butyl rubber composition which exhibits improved adhesion to pre-treated polyester textile materials, while at the same time important physical properties of cured butyl rubber such as modulus, tensile strength and elongation are maintained or even enhanced. The vulcanizable composition of the invention is based on a blend of butyl rubber and minor amounts of a copolymer of ethylene with a lower alkyl acrylate or methacrylate, or a terpolymer of ethylene, a lower alkyl acrylate or methacrylate and acrylic or methacrylic acid. The composition of this invention exhibits improved adhesion to pre-treated polyester textile materials. The invention also relates to laminates of the butyl rubber compositions of this invention with polyester textile materials such as yarns and woven fabrics.

Title: Read device
Inventor: TIMMERMANS JOZEF MARIA KAREL
IPC: H04N9/877
Filed: 1991-09-18
Abstract: A read device (320) is disclosed for reading a record carrier (184) on which coded pictures (4TV, TV, TV/4) have been recorded.  The recorded coded pictures represent pictures made up of a matrix of P rows of Q pixels (p). The dimension of the pixels in a horizontal direction is substantially equal to the dimension of the pixels in a vertical direction. A read unit (6) reads the recorded coded pictures (4TV, TV, TV/4) from the record carrier (184). The device comprises a picture converter, which preferably comprises a sample rate converter (290), for converting the read-out coded pictures into an adapted coded picture comprising P'xQ' coded pixels. The sample rate converter is arranged in a data path between the read unit (6) and a picture memory unit (321). The picture memory unit (321) supplies a coded picture representing a picture made up of pixels (p') whose ratio between the dimension in the horizontal direction and the dimension in the vertical direction is substantially equal to Q/P, P and Q being integers. The coded pictures supplied by the picture memory unit (321) are converted into a video signal suitable for a standard TV set. As a result of the use of a sample rate converter (290) the picture memory unit (321) can employ a picture memory (255) having the same number of rows and columns, which number is equal to a power of 2. Such memories can be constructed simply by means of commercially available memory circuits. Moreover, this yields a substantial reduction of the speed with which the coded picture information is extracted from the picture memory. In addition, through the use of the sample rate converter (290) it is simply possible to obtain a rotaed representation of the picture on a display screen with the display screen being filled correctly.

Inventor: JOMES RAYMOND
IPC: B03D1/14
Filed: 1992-07-02
Abstract: A highly versatile fluids and particulate separator that can be used in a centrifugal mode or centrifugal with gas flotation mode without the use of rotating apparatus within the cell. A pump and recirculation system provide the means for centrifugal force and gas flotation. A buoyant self adjusting discharge assembly with a vortex of fluids surrounding it provide the exit path for separated light fluids and light particles. In oil and water separation the buoyant assembly allows self discharge of the oil and can be used with high oil to water ratios at high volume. Oil spill cleanup is possible. Conversely gas flotation may be used for low volume separating applications.

Title: Window purging system for a combustion instrument
Inventor: MYHRE DOUGLAS C
IPC: G01J5/04
Filed: 1991-01-14
Abstract: ABSTRACT OF THE DISCLOSURE    A purging air flow system that causes air to pass over a pyrometer lens or window (28) to keep it clean and free from particulate contaminants has an annular, continuous slot (50) for air inlet around the periphery of the lens (28) to permit flow of air across the lens (28) without any obstructions in the path of flow inwardly from the outer edge of the lens (28).  An asymmetric flow pattern is established across the lens surface, either by having a differential size slot (50) at different peripheral portions of the peripheral edge of the lens or window (28), or by providing a radial swirl about the axis of the window (28) so that when the air goes through the slot (50), the tangential velocity creates a moving asymmetric flow pattern on the window surface (28A).

Title: Hydro-electric power conversion system
Inventor: BELLAMY NORMAN W
IPC: F03B13/00
Filed: 1991-03-28
Abstract: The low head energy in for example a river flow is used to provide electrical energy by directing the water through a duct (70), and by inducing air into the duct to create an air flow which is drawn over an air turbine (76) to excite same, and thereby produce electrical energy. The air can be introduced into the flowing water in the duct by a switching arrangement to ensure that no bubbles or pockets of air travel along with the water, which impaires efficiency. The duct may be in the shape of an anti-gravity course (70) to prevent the bubbles from travelling.

IPC: A61K8/92
Filed: 1993-05-07
Abstract: ABSTRACT OF THE DISCLOSURE A conventional method of ensuring a positive slip-resistant hand grip on exercise or sporting equipment such as weight lifting equipment requires that the participant liberally applies chalk to the palms and fingers of the hands. A simpler, more effective method is to provide a mixture of ethyl alcohol and powdered rosin in the ratio of 3:1. When applied to the athletes' hands, the alcohol flashes, leaving a sticky residue on the palms and fingers. The residue normally lasts a complete sporting session before simply wearing off, but may be prematurely removed by washing in cold water either a grit based soap or hand cleaner. Fragrance may optionally be added to the mixture to render the mixture pleasant smelling.
