Title: Fat-reduced butters
Inventor: CRUMPLEN CARL M
IPC: A23C15/16
Filed: 1993-02-15
Abstract: TITLE               Improvements in Fat-reduced Butters ABSTRACT     An unadulterated, edible water-in-oil emulsion having a reduced butterfat content relative to butter, but containing not less than about 30% by weight butterfat.  The emulsion comprises a combination of native butterfat and, buttermilk, wherein an initial mixture of same in a water-in-oil emulsion at a temperature of from greater than 30 to about 34.0 degrees C is passed through:  a first, upstream scraped surface heat exchanger; an emulsion-working intermediate crystallizer operating under fat crystallization promoting/emulsion softening conditions; and, a second scraped surface heat exchanger.   These are operated under conditions  selected  to  substantially  avoid  any  increase  in  the temperature of the emulsion and to effect an overall reduction of the temperature of to between greater than 14 to about 17.0 degrees C.  The temperature is reduced primarily in the first heat exchanger, remains more  or  less  unchanged  in the  intermediate  crystallizer,  and  is thereafter generally actively maintained throughout the second heat exchanger.  The emulsion is cooled and rotated into and out of heat exchange-surface contacting relation so as to avoid emulsion-channelling there  through  and  thereby promote  homogeneity  of  butterfat crystallization.   The  crystallized emulsion product  is  relatively physically stable, and is even printable.

Patent CA-2105394-A1 (CA)
Title: Sensor devices
Inventor: VADGAMA PANKAJ M
IPC: C12Q1/26
Filed: 1992-03-12
Abstract: Analytical sensor devices incorporating a permselective medium immobilised as a continuous liquid or gel phase barrier between sample and detector. The barrier is electrically insulating, impermeable to charged non-lipophilic species, selectively partitions lipophilic species diffusing through it, and its selectivity can be controlled or optimised by pH adjustments. The preferred barrier form has the permselective medium (e.g., a lipid or ester) immobilised by incorporation as plasticiser in a polymer (especially PVC). The preferred detector is an electrode, especially of non-potentiometric type. The sensor can be used to detect components as such or indirectly by allowing them to react to produce other materials to which the detector responds (e.g., an ionic species or an ion concentration or activity change) and is also applicable to detecting neutral or small uncharged hydrophilic species, e.g.  hydrogen peroxide, especially that formed by enzyme action in the sensor or detector system.

Title: Continuous Process for Expanding Thermoplastic Minipellets
Inventor: HALL THOMAS N III
IPC: C08J9/18
Filed: 1993-09-28
Abstract: The subject invention pertains to a continuous process for expanding thermoplastic minipellets, particularly polypropylene.  The minipellets are continuously expanded by continuously charging and mixing water and minipellets in a slurry tank to form a slurry which is subsequently pressurized.   A blowing agent such as butane is entrained into the pressurized slurry flow, which said slurry is then heated by a heating means, such as a shell and tube heat exchanger, to the softening point of the minipellets.  The heated minipellets are given the time necessary for impregnation by permitting them to flow through one or more impregnation vessels.  The impregnated minipellets are released through an orifice into an expansion vessel where the blowing agent flashes off, thereby expanding the minipellets.

Title: Signal routing circuit for microprocessor upgrade socket
Inventor: STANCIL CHARLES J
IPC: G06F15/78
Filed: 1993-04-28
Abstract: ABSTRACT               SIGNAL ROUTING CIRCUIT FOR MICROPROCESSOR UPGRADE SOCKET    A computer system can be upgraded from a 386 main CPU to a 486 microprocessor without exchanging the processor card or removing the 386 microprocessor.  The computer includes a single empty socket which can be fitted with a 486SX, 487SX, or 486DX microprocessor. Any of these microprocessors can be plugged into the socket, which causes the cache system which includes an 82395 to enter a tri-state test mode and suspends the operation of the main CPU.  To correct for the variations in the pin arrangements of each processor, various system signals are routed using switches to different pins for different microprocessors.  In addition, specific system signals are rerouted among the system components using a set of six switches to provide for proper operation when the socket is empty and when it is occupied.  By appropriately setting all of the switches, the correct signals are provided to each pin of the upgrade microprocessor.  While the cache system remains in test mode, the main CPU remains fundamentally inactive, and the upgrade processor controls the computer system.

Patent CA-2114760-A1 (CA)
Title: Locking ring for an acetabular cup
Inventor: ROHR WILLIAM
IPC: A61F2/34
Filed: 1994-02-02
Abstract: The metal lock ring of the invention has an oblong exterior periphery which allows the ring to have a small "width" and a larger "height." The small "width" provides a strong locking mechanism on the poly liner and the larger "height" allows the ring to remain secure within the groove of the metal shell prior to and during assembly of the polyethylene liner. The ring has a chamfer on its inside leading edges defining its width to facilitate assembly of the liner. This optimizes the ease of assembly and is simpler and more economical to produce than a chamfer all the way around the oblong ring. In the preferred embodiment, the lock ring has a constant thickness such that the inner periphery and the outer periphery are oval.      In an alternative embodiment, the metal lock ring has a round inner diameter and a round outer diameter that are not concentric, thereby creating a thickening of the ring at one end. The shape of the alternative lock ring provides for substantial contact between the lock ring and the poly liner about the liner. The thickened area of the ring retains the ring within the metal cup prior to and during assembly of the poly liner. The thickened portion of the ring may have scallops or notches formed therein to increase the flexibility of the ring.
