Title: Process for modifying hydrophilic polymers
Inventor: ENGELHARDT FRIEDRICH
IPC: B01F3/12
Filed: 1992-09-17
Abstract: ABSTRACT        The present invention relates to a process for modify-ing hydrophilic polymers by mixing with a modifier.  In the process, the pulverulent polymer and the modifier are introduced continuously into a vertical, cylindrical mixer, mixed at a power of from 1,000 to 5,000 Wh/m3 of powder by means of rotating blades at a blade rate of from 100 to 300 s-1 at a residence time of 1 - 10 seconds, during which the powder is passed through zones having energy dissipation densities of 300 - 600 W/l of mixer volume.  The process ensures homogeneous mixing of the modifying components with the pulverulent polymer within a very short time, thus ensuring uniform coating of the surface of the powder particles.

Inventor: KORTSCHOT CORNELIS
IPC: A23G9/48
Filed: 1992-10-22
Abstract: A frozen dessert such as ice cream, and a process for manufacturing same, are described.  The chocolate or other flavouring composition is injected into the stream of semi-frozen dessert in the form of a pumpable semi-liquid which freezes into ribbons or strands upon contact with the dessert. The fat and oil fractions of the flavouring composition are formulated so that the composition can be conditioned from a solid or semi-solid paste into a high-viscosity semi-liquid composition which can be pumped with a positive-delivery pump, and so that as soon as the composition is cooled a few degrees by being in direct contact with the ice cream, the viscosity rises rapidly and the composition once again becomes a solid or semi-solid.  The conditioning can be accomplished in one of at least two ways.  Firstly, the flavouring composition can be conditioned from the temperature at which is is a semi-solid paste, to a few degrees above that temperature.  Secondly, the flavouring composition can be fully melted at an elevated temperature, and then supercooled to below the temperature at which it would be a semi-solid paste under steady-state conditions, agitating it to prevent crystallization.  The preferred formulation for the flavouring composition is 46.61% fractionated and partially hydrogenated vegetable oils, 32.95% sucrose, 20.04% cocoa powder, and 0.40% lecithin.  The vegetable oil composition is 91.8% Oleic, Stearic and Palmitic fractions, namely 10.8% Palmitic, 7.3% Stearic, and 74.7% Oleic.

Abstract: A double, back to back oriented mechanical end face seal for use in sealing toxic or corrosive fluids having an intermediate buffer fluid chamber into which a relatively inert gas, such as nitrogen, is provided for use as a buffer fluid.      The nitrogen gas is maintained at a pressure which exceeds the process fluid pressure by at least 10 p.s.i. and, in a preferred embodiment, spiral pumping grooves in the mating rings of each of the seals are shaped and dimensioned to pump the nitrogen buffer gas through the first seal from the intermediate chamber into the process fluid chamber and through the second seal from the intermediate chamber into the environment external to the housing and sealing area, thereby avoiding the escape of the process fluid into the intermediate buffer chamber and to the atmosphere.      Contamination of the process fluid by the buffer gas may be tolerated. The buffer gas may be any relatively inert gas, a gas which is non-hazardous to the environment and also, is compatible with he process fluid used; appropriate examples are nitrogen, carbon dioxide; air or one of the noble gases. The seal can be used to seal a process fluid which is either a liquid or a gas.

Title: Process for manufacturing cast silicate-based detergent
Inventor: OLSON KEITH E
IPC: C11D3/37
Filed: 1992-01-21
Abstract: A process for producing a solid cast silicate-based cleaning compositions which includes the step of combining appropriate concentrations of an alkali metal silicate, an alkali metal hydroxide and a source of water to form a reaction mixture that solidifies into a reaction product which is processable at temperatures below the melting point or decomposition temperature of the reaction product. The process provides for the rapid manufacture of a solid cast alkaline cleaning composition without melting of the cast composition. Incorporation of appropriate amounts of a combination of a polyacrylate and a phosphonate into the cleaning composition cooperate with the silicate present in the composition to form a threshold system which is effective for controlling precipitation of both calcium and magnesium in a use solution.

Title: Bit rate control for hybrid dpcm/dct video codec
Inventor: WANG LIMIN
IPC: H04N19/126
Filed: 1993-08-31
Abstract: ABSTRACT      A method and apparatus are provided for regulating the bit stream generated by a hybrid DPCM/DCT video codec so that the  compressed  bit  stream  at  a  variable  rate  can  be transmitted  over a  fixed  rate  channel.    The  bit  rate regulation is accomplished by appropriately quantizing the DCT coefficients where the quantization stepsize is obtained by multiplying a fixed weighting matrix by a scaling factor.  For each frame, a single quantization scaling factor is determined by iteratively comparing the output bit rate with the target bit rate which is based upon the desirable bit rate, frame code mode  and  scene  changes.   The  iterative  comparison guarantees a quantization scaling factor which results in a minimum accumulated bit rate difference from the target bit rate for each frame.
