Filed: 1992-10-08
Abstract: POLYMER POLYOL DISPERSANTS FROM POLYMERS CONTAINING ANHYDRIDE GROUPS Abstract of the Disclosure Dispersants that are the reaction product of polyoxyalkylene polyether polyols with polymers containing anhydride groups are discussed. These dispersants may be used in the production of polymer polyols having high styrene contents and high solids contents. The polymers containing the anhydride groups may be preformed polymers which are then reacted with the polyol, or may be formed in the polyol directly prior to esterification with the polyol to form the dispersants. Maleic anhydride and methacrylic anhydride and derivatives thereof are examples of monomers suitable for the dispersants. Polymer polyols made using these dispersants may be reacted with polyisocyanates to produce polyurethanes. :

Title: High efficiency digital data encoding and decoding apparatus
Inventor: TSUTSUI KYOYA
IPC: G10L19/02
Filed: 1992-03-27
Abstract: An apparatus for compressing a digital input signal compresses a digital input signal arranged into frames of plural samples. The digital input signal is orthogonally transformed by plural orthogonal transform circuits in blocks derived by dividing the frames by a different divisor in each circuit. The resulting spectral coefficients are quantized using an adaptive number of bits. The output of one orthogonal transform circuit is selected based on the outputs of the orthogonal transform circuits. The digital input signal is divided into plural frequency ranges, and frames are formed in each range. A block length decision circuit determines division of the frames of each range signal into blocks in response to range signal dynamics.  The range signals are orthogonally transformed in blocks and the spectral coefficients are quantized. The apparatus also includes a frequency analyzing circuit that derives spectral data points from the input data, and groups them in plural bands. A noise level setting circuit finds the energy in each band and sets a allowable noise level in response to the band energy. A block floating coefficient calculating circuit calculates block floating coefficients based on the maximum spectral data point in each band. A quantizing bit number decision circuit determines the number of bits to use for quantizing in response to the allowable noise level and the block floating coefficients. A quantizing circuit quantizes the spectral data points in response to the quantizing bit number decision circuit.

Title: Non-fat natural cheese
Inventor: KERRIGAN GARY L
IPC: A23C19/028
Filed: 1991-08-14
Abstract: The present invention is directed to a non-fat natural cheese which is made from a first non-fat milk solids substrate which is made into cheese by various known methods. In the method for making the substrate, a non-fat milk solids source, such as skim milk, is acidified to a pH below the isoelectric point. A blend of the acidified non-fat milk solids source and gum is then prepared.  The blend is then subjected to high pressure homogenization to provide a dispersion of the gum in the casein of the non-fat milk solids source. Alternatively, the gum may be dispersed in water and be subjected to high pressure homogenization prior to blending the gum with the acidified skim milk. In this embodiment, only mild low shear mixing is required to provide a dispersion of the gum in the casein of the non-fat milk solid source. The casein/gum dispersion is then combined with a second non-fat milk solids source to provide a non-fat milk solids substrate. The substrate can then be used to prepare non-fat natural cheese by various known methods.

Abstract: The switching element allows building up of ATM exchanges capable of processing cell flows at bit rates higher than 700 Mbit/s. It uses an architecture with output queues, implemented through a unique shared memory, suitably controlled in order to obtain spatial cell switching towards the outputs. ATM cells are converted into a highly parallel format by a structure named rotation memory, where through the cells are then transferred into the master memory. The rotation memory is used also for the inverse operations of format restoration towards the output. The element control circuit is entrusted with the generation of writing and reading addresses of the master memory, in order to carry out the switching proper.
Patent CA-2092942-A1 (CA)
Inventor: CARTER MARK L
IPC: H04N7/18
Filed: 1993-03-30
Abstract: A flitch or cant is successively transported by a pair of differentially operated clamps, first to a scanning station, and then to a sawing station where the wane is removed. A series of flitches are processed in this manner such that as the wane edge from a first flitch is sawn, a next flitch in succession is optically scanned. The sawing and scanning is accomplished by means of a combination saw and scanner which moves in a direction longitudinal of the flitch as respective flitches are held in stationary positions at the sawing station and at the scanning station. Between passes of the saw-scanner combination, the sawn flitch is conveyed away and the next flitch in line is conveyed forwardly to the sawing position while being skewed by the clamps in accordance with the characterization generated by the scanner.      The scanner extends outwardly from the side edges of the flitch to provide a radiation beam directed obliquely inwardly and downwardly from a point displaced along the flitch from the location where the radiation image intersects the flitch and provides a line image. Television cameras also disposed to the side of the flitch view the line image at an oblique angle, but the cameras are positioned along the flitch in a second direction opposite the direction where the radiation source was located. The cameras "see" the line images on the side edge of a flitch substantially face on.

Abstract: A variable speed control system for a single phase AC induction motor wherein a controllable switch is in series with the main winding of the motor, while the auxiliary winding of the motor, which is in series with a capacitor, is continuously energized.  The switch is opened whenever the current through the main winding passes through zero.  While the switch is open, the back e.m.f. in the main winding is sensed to provide a measure of the speed of the motor.   This is compared with a desired speed signal and the comparison is utilized to control closure of the switch.  The speed of the motor then remains constant at the desired speed, even with a varying load.

Abstract: La demande de brevet porte sur le concept d'un équipement servant à faire fondre la neige ayant la particularité de fonctionner à partir de brûleurs à flamme vive. La fondeuse se présente comme une boîte métallique rectangulaire ayant vingt pieds de longueur par dix pieds de hauteur et dix pieds de largeur (20' X 10' X 10') qui elle-même sera fixe ou mobile, dans ce dernier cas étant alors montée sur une remorque. L'arrière de cette boîte, s'ouvre pour y permettre directement le déversement des neiges lorsqu'elle est sur le sol, et à partir d'une rampe d'accès lorsqu'elle est sur remorque . Des moyens de convoyage introduisent graduellement la neige à partir du réservoir vers la chambre de fonte. La densité ou l'épaisseur de la neige ainsi transportée est contrôlé par des grattoirs mus par moteur diesel. Ceux-ci font passer la neige sous une série de brûleurs à gaz ou autre combustible dégageant une flamme nue. L'eau ainsi obtenue est rejetée dans les égoûts ou à tout autre endroit déterminé par un système de drains et de bacs de récupération placés directement sous la chambre de combustion.

Abstract: A melting casting process produces meltable metal cores for subsequent molding of components made of plastic material and encapsulated components such as turbine blades so they may be held for machining. The process utilizes a double acting piston (12) in a cylinder (10) to permit unlimited dispensing capacity without having to pause between piston strokes. The apparatus comprises a tank (32) for containing molten metal, a double acting cylinder (10) having both ends closed and an injection piston (12) therein and an operating mechanism for reciprocating the piston (12) in the cylinder (10). Valve mechanisms (20, 26) are provided so that when the piston (12) is moved in either direction in the cylinder (10), a flow of molten metal passes through an injection passageway (42) into a die (46), and molten metal from the tank (32) fills the space behind the moving piston (12) thus the cylinder (10) always remains full of molten metal.
