Title: Low calorie fat-containing frozen dessert products having smooth, creamy, nongritty mouthfeel
Inventor: WHELAN RICHARD HOWARD
IPC: A23G9/32
Filed: 1991-01-28
Granted: 1997-12-09
Abstract: Low calorie frozen desserts, in particular ice cream-like products, having a smooth, creamy, nongritty mouthfeel are disclosed. These frozen desserts contain fat comprising from about 30 to 100 % of certain edible, wholly or partially nondigestible intermediate melting polyol polyesters, milk solids other than fat. sweetener, oil-in-water emulsifier, a flavoring substance, and water. The fat is substantially homogeneously dispersed in the aqueous phase as emulsified fat particles having an average particle size of about 5 microns or less. These frozen desserts are obtained by a process which initially involves the formation of a preemulsion by homogenizing a mixture which consists essentially of these intermediate melting polyol polyesters and only a portion of the other dessert ingredients. This preemulsion is then combined with the remaining dessert ingredients, homogenized, pasteurized, and at least partially frozen to provide the frozen desserts.

Title: Disintegration of baled crop materials
Inventor: BUSSIERE RAYMOND
IPC: A01F29/00
Filed: 1992-12-31
Granted: 1995-01-03
Abstract: Apparatus for disintegrating baled material in the form  of  large  cylindrical  bales,  a  collection  of  small rectangular  bales  or  large  rectangular  bales  includes  a hopper for receiving the baled material.  At the base of the hopper  is provided  a  flail  cylinder  which  engages  the material and sweeps it around to an ejection slot along one side of the hopper.  Above the flail cylinder is provided a pair of  support rollers  each on a respective side of the flail cylinder with the axes parallel to the flail cylinder.       The rollers can be rotated in either direction to provide a vigorous rotating action of the baled material despite flat edges of the baled material.   The rollers are mounted so that  they  can  lift  from  the  surface  of  the  hopper  if material passes between the underside of the roller and the inside  surface  of  the  hopper  on  its  way  to  the  flail cylinder.

Title: Translation buffer for virtual machines with address space match
Inventor: MASON ANDREW H
IPC: G06F12/10
Filed: 1992-06-25
Granted: 1996-08-13
Abstract: A CPU executing a virtual memory management system employs a translation buffer for catching recently used page table entries. When more than one process is executing on the CPU, the translation buffer is usually flushed when a context switch is made, even though some of the entries would still be valid for commonly-referenced memory areas. An address space number feature is employed to allow entries to remain in the translation buffer for processes not currently executing and the separate pro-cesses or the operating system can reuse entries in the translation buffer for such pages of memory that are commonly referenced. To allow this, an "address space match" entry in the page table entry signals that the translation buffer content can be used when the address tag matches, even though the address space numbers do not necessarily match. When executing virtual machine, on this CPU, with a virtual machine monitor, the address space match feature is employed among processes of a virtual machine, but an additional entry is provided to disable the address space match feature for all address space numbers for the virtual machine monitor.

The fan and noise muffling assembly (13) includes a radial fan (60) driven by the motor (24) and a muffler housing (62) which includes a generally cylindrical side wall (68). Air is drawn in through the apertures (53, 55) by the fan (60) and is caused to pass by the motor (24) within the pedestal (37) to cool the motor (24). It then passes through an aperture (66) in an orifice plate (61) and as directed by the fan (60) against the side wall (68). At that point the air turns ninety degrees downwardly and is directed into four chambers (73) below the fan (60), the chambers (73) being formed by ribs (74) extending radially outward from a hub member (75) positioned below the fan (60). The air then again turns ninety degrees inwardly into two chambers (76) divided by a rib (77) below the hub member (75) whereby it turns again and leaves the blender (10) through an air exit aperture (70).

Title: Apparatus for operating bin lid from below
Inventor: POLLOCK EUGENE B
IPC: E05F11/04
Filed: 1992-11-12
Granted: 2002-01-01
Abstract: An apparatus for opening and closing a top bin lid (24) from below such that, when in the fully opened position, the lid (24) will not extend above the plane of the opening. The apparatus utilizes an elongated lever arm (32) pivotally mounted on the pivot axis (28) of the bin lid (24). A flexible linkage, such as a chain (34) extends from below, over the lever arm (32) which holds the lid (24) in the closed position until the chain is pulled from below. After the latch (30) is released, further drawing of the chain will pivot the lid and arm about their common pivot axis (28) until the arm (32) is obstructed from further movement by the bin (10). Continued pulling of the chain will draw he lid toward the lever arm against spring pressure until the lid (24) has been pivoted approximately 180° from its closed position.  Controlled re-lease of the chain will cause the spring pressure to move the lid over the vertical plane of the pivot axis and thereafter the force of the spring and gravity will return the lid and latch back to the closed position. The lever arm includes a lid engage-ment tab which returns the lever arm to its upwardly extending position when the lid closes.

Title: Energy saving power control system
Inventor: BANGERTER FRED F
IPC: H05B41/392
Filed: 1994-03-31
Granted: 2000-02-22
Abstract: Apparatus and methods for AC power regulation primarily intended for inductive loads (e.g., fluorescent lights, motors, etc.) which provide substantial reduction in power consumption while also providing a leading power factor, reduced harmonic distortion, reduced crest factor and reduced noise. The system is self-adjusting for a wide range of loads and can reduce power consumption by 25 percent in lighting loads while producing minimal reduction in light output. The system utilizes a Triac (32) and parallel capacitor bank (58) in series with the load (22). The Triac (32) is turned on in response to a near-zero differential voltage measured across the Triac (32) and is turned off near the peak of each AC half cycle by shunting current around the Triac (32). The capacitor (60) absorbs the inductive turn-off voltage spike caused by the collapsing magnetic field in the ballast at the instant of Triac turnoff. This energy, in turn, provides longer on-period for the lamp, thereby permitting more light and increased operating efficiency. The turn-off time is adjusted to regulate power at a reduced level responsive to line voltage, load current and load power-sense signals.

Title: Process and device for producing drive belts with small rotation-angle error
Inventor: TESSMANN UWE
IPC: B24B7/12
Filed: 1995-11-10
Granted: 1999-09-21
Abstract: In order to produce drive belts with small rotation-angle error, the rotation-angle error of a specific drive belt (6) is measured. Instead of the selection of low-error drive belts, the invention provides that, after the measurement has been performed, the drive belt is physically altered in a part of its length, in such a manner that the rotation-angle error is rendered more or less equal to zero. According to the invention, this physical alteration of the drive belt (6) is realized by the removal of material - effected, for example, by a grinding operation - from the contact surface (7) of the drive belt (6) according to the measured rotation-angle error. For every type of belt, there exists a clear relationship between the rotation-angle error and the amount of grinding required for the correction thereof, it being possible empirically to determine said relationship.
