Patent CA-2245899-A1 (CA)
Inventor: LANGBERG EHUD
IPC: H04L7/00
Filed: 1997-02-14
Abstract: An "N" channel receiver system (100) includes "N" A/D converters (103a-103b), one per channel, sampling the data received by their respective channels. The sampling rate of the A/D converters (103a-103b) is controlled by a sampling clock signal (104) generated by a timing recovery circuit (107). One rate of the sampling clock is a function of a timing signal (160) applied to the timing recovery circuit (107). The band edge filters (113a-113b) are coupled to each channel of the receiver for producing N distinct timing signals (TSaTSb) corresponding to the data signals received by each one of the N channels. The N distinct timing signal (TSa-TSb) are coupled to a channel selector (155) for selectively coupling one of the N distinct timing signals having highest SNR to the timing recovery circuit.

Abstract: A process for making a cladding for a nuclear fuel rod is disclosed which includes the following steps. First, at least two layers of zirconium-based metals are spray-deposited on a generally cylindrical substrate in a manner that provides a rough, cylindrically-shaped, porous billet. The zirconium-based metal for each layer is different from an adjacent layer and is selected to provide a desired combination of properties. Next, the substrate is removed from the spray-deposited material, thereby providing an elongated tube hollow.  The spray-deposited material is then consolidated in a known manner to remove the porosity, densify the tube hollow to substantially full density, and reduce the cross-sectional dimension of the tube hollow to a desired size. In a further step the consolidated tube hollow is annealed under conditions of time and temperature selected to relieve stresses imposed on the tube hollow during the consolidation step and to provide a desired combination of properties in the densified zirconium-based metal layers.

Abstract: A sound capturing method and device for use in making recordings having improved three-dimensional imagery during playback. Vibration information is detected from a body portion through the use of a crystal microphone for generating a first signal corresponding to a vibrational frequency of the body portion in response to a received sound wave. Direct sound information is detected from the body portion through the use of a condenser microphone affixed thereto at a second location for generating a second signal corresponding to a frequency of the received sound wave. The first and second locations are in proximity to one another such that a sound wave will reach each location at substantially the same time. Alternatively, the signals received at either location may be processed or time-delayed such that sound waves are recorded from each location at substantially the same time. The resultant first and second signals may be combined through the use of a mixer and then put into a conventional sound recording device.

Title: Laminated fuel and vapor return lines
Inventor: HUNTER ROBIN B
IPC: B29C48/49
Filed: 1997-05-15
Abstract: A multi-layer hydrocarbon vapor-impermeable tube (11) is formed with a nylon outer layer (12) and a vapor barrier inner layer (15) such as ETFE, bonded together by two adhesive layers. The laminated tube is coextruded. The shear on the two adhesive layers are adjusted to bias the first adhesive layer (13) towards the nylon outer layer and the second adhesive layer (14) towards the ETFE barrier layer (15). This permits rapid coextrusion of the laminated tubing. Preferably, both adhesive layers are formed from a blend of nylon and ETFE. The ratio of nylon to ETFE can be adjusted so that the first adhesive layer is preferentially adherent to the nylon layer, and the second adhesive layer is preferentially adherent to the ETFE layer, and both adhesive layers are adherent to each other.

Title: Water-dispersible wet wipe
Inventor: ENGEL STEVEN ALEXANDER
IPC: D21H27/40
Filed: 1997-06-10
Abstract: A premoistened wet wipe provides functional wet strength in use, yet is dispersible if flushed down the toilet so that plumbing and sewage treatment facilities do not become clogged. A particular embodiment of the wipe consists of three uncreped through-air-dried tissue plies that are attached to each other by edge embossing. The two outer plies contain a wet strength agent to provide wet poke-through resistance to two large, centrally-located unembossed regions. The center ply contains no wet strength agent to aid in dispersibility.     The embossing around the edges of the wipe further degrades the strength of the wipe in the embossed areas to assist in dispersibility when the wipe is flushed.

Title: An adaptive method for channel assignment in a cellular communication system
Inventor: BARRATT CRAIG H
IPC: H04B7/005
Filed: 1997-10-10
Abstract: An adaptive method for channel assignment (500) in a cellular multiple access wireless communication system that has a cell station (100) and a number of subscriber stations (25, 26, 27) augments existing channel assignment protocol and thus is downward compatible with existing time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), and spatial division multiple access (SDMA) system protocols. The method adaptively determines the power required for establishing an acceptable quality connection between a subscriber station (25) and the cell station (100) and provides an early warning trial signal for advising existing connections that a new connection is about to be established. The early warning, followed by a pause, provides a basis and a time interval for taking corrective interference action if the trial signal indicates that an unacceptable level of interference will result if the trial connection is established. The early warning signal and associated pause are useful for intracellular and intercellular interference management.
