Title: Liquid dentifrices
Inventor: DAWSON PETER LEONARD
IPC: A61K8/73
Filed: 1992-06-03
Abstract: J 7026 (R) ABSTRACT            The present invention relates to liquid dentifrices which contain particulate abrasive material, stably suspended in an aqueous vehicle with the aid of a polysaccharide gum as suspending agent. It has been found that high levels of the particulate abrasive material can be stably suspended with less polysaccharide gum than in the prior art, if a small amount of an alkalimetal bicarbonate is included in the dentifrices. This also significantly reduces the loss of available F- in the dentifrice if a fluorine-containing anticaries agent such as sodium monofluorophosphate is included.

Title: Gypsum board coating
Inventor: DAVIE IAN N
IPC: C04B41/61
Filed: 1992-06-04
Abstract: ABSTRACT         A gypsum board having an integrated moisture vapour barrier layer of an improved moisture vapour impermeability is disclosed.  The layer is applied to the surface of the board by curtain coating a hot melt of a material comprising a natural or synthetic wax, such as a paraffin or polyethylene wax and, for example, an ethylene-vinyl acetate copolymer or a microcrystalline wax, and permitting the melt to cool.  To improve the integrity of the moisture vapour barrier layer by reducing the formation of pinholes and blisters during the curtain coating, a layer of a paraffin or microcrystalline wax may be applied to the surface of the board, for example by brushing or spraying, prior to curtain coating.

Title: Method and apparatus for accommodating a variable number of communication channels in a spread spectrum communication system
Inventor: BRUCKERT EUGENE J
IPC: H04B1/707
Filed: 1992-02-24
Abstract: A method and apparatus is provided for transmitting spread spectrum signals.  The transmitter (242) receives data symbols (214). Subsequently, the transmitter (242) splits (244) each particular set of two received data symbols (214) into a first and second array of data symbols (252, 254) according to either of two algorithms.  The first algorithm includes providing both data symbols (214) of the particular set to the first and second array of data symbols (252, 254) and the second algorithm includes providing one of the data symbols (214) of the particular set to the first array of data symbols (252) and the other of the data symbols (214) of the particular set to the second array of data symbols (254).  Subsequently, the transmitter (242) determines particular channels to transmit the first and second array of data symbols (252, 254) by spreading (232, 234) the first and second array of data symbols (252, 254) with a predetermined length Walsh code (216).  The transmitter (242) accommodates a variable number of data channels by selecting a particular algorithm from a group consisting essentially of a first algorithm and a second algorithm and setting the predetermined length Walsh code (216) in response to the particular algorithm selected.

Patent CA-2082674-A1 (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1992-11-12
Abstract: The present invention is an improvement to a process for the cryogenic distillation of air to produce both nitrogen and oxygen products carried out in a single distillation column system wherein a feed air stream is distilled thereby producing a nitrogen overhead and a liquid oxygen bottoms. The improvement is characterized in that: (a) operating the single distillation column at a pressure between 70 and 300 psia [480 and 2,070 kPa(absolute)]; (b) withdrawing a portion of the liquid oxygen bottoms having an oxygen concentration greater than 80% oxygen and preferably between 85% and 97% oxygen from the bottom of the single distillation column and reducing the pressure of and vaporizing the withdrawn liquid oxygen by heat exchange against a condensing nitrogen stream removed from a top section of the single distillation column; (c) feeding the condensed, nitrogen stream to a top section of the single distillation column as reflux; and (d) recovering the vaporized oxygen as at least a substantial portion of the oxygen product. The improvement can be further characterized by providing boilup by boiling at least another portion of the liquid oxygen bottoms by heat exchange against a condensing vapor stream, wherein the vapor stream to be condensed is an air stream at a higher pressure than the feed air stream or a recycle nitrogen stream at a pressure greater than the operating pressure of the single distillation column, or by recycling a portion of the oxygen product at a pressure of at least the operating pressure of the single distillation column to the bottom of the distillation column and/or by providing intermediate boilup to the stripping section of the single distillation column system by vaporizing a portion of descending column liquid by heat exchange against another condensing vapor stream, wherein the other vapor stream to be condensed is either an air stream at a higher pressure than the feed air stream or a recycle nitrogen stream at a pressure greater than the operating pressure of the single distillation column. The process of the present invention is particularly suited to integration with gas turbines.

Title: Vertical axis wind turbine
Inventor: LUBBERS JOHN
IPC: F03D3/06
Filed: 1992-12-08
Abstract: Abstract of the Disclosure A wind turbine is described which includes a vertical axle mounted for rotation to drive an output utilization device.          Around the axle is arranged a circumferential array of wind vanes, each wind vane comprising a generally rectangular panel of flexible material supported in a frame and having a pocket opened along a vertical side which is able to flare out and catch the wind in one direction but collapse upon rotation around to the opposite direction, allowing a net output power to be generated by the wind impinging on the wind vane pockets being received in the wind vane pockets.  A successive opening of the pockets insures a rapid opening action. A releasable hinging of the wind vane frame allows spilling of winds at excessive wind speeds.

Patent CA-2091754-A1 (CA)
Inventor: ELLIOT PATRICK W
IPC: G10L25/24
Filed: 1991-09-25
Abstract: In a Code Excited Linear Prediction (CELP) analogue signal coding system sequences from a master codebook (40), which may be a one dimensional codebook, are filtered (42) and then stored in slave codebooks (70, 72). Input analogue signals (20) are filtered (34, 36) and compared orthogonally (66, 78, 80) with sequences from the slave codebooks and an optimum pair of se-quences are selected. Since the comparisons are orthogonal, sequences can be selected from the codebooks (70, 72) and compared (78, 80) with the filtered incoming analogue signals entirely independently.  Reduced length sequences from the master codebook may be compared with orthogonalised analogue signals since orthogonalised signals contain some redundancy. The master code-book may not need to be orthogonalised in some circumstances. Various means of orthogonalisation of the sequences are possible including separation into odd and even sequences. Further orthogonalisations are possible, for example to give four comparisons.

Filed: 1993-09-22
Abstract: A multiple-master, digital communication technique is provided which employs standard universal asynchronous receivers and transmitters ("UARTs") linked to a common data transmission bus, and a hardware-based inter-station contention scheme utilizing a bus separate from that employed for data transmission. This communication technique effectively eliminates any window of collision for data transmission  on the bus, and greatly reduces the amount of software processing required to resolve contention between stations. In addition, the hardware required to support the dedicated contention bus scheme is comprised of inexpensive, commercially available logic gates.
