Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power.

Title: Adjustable merchandise display structure
Inventor: WALRATH JOHN
IPC: A47F5/08
Filed: 2000-03-23
Granted: 2007-05-22
Abstract: A merchandise display system has a carrier supported by an array of adjustably interconnecting arms from a mounting base. The mounting base is connectable to a mounting structure in a variety of different orientations so that the carrier can be displayed as desired. The mounting base has a clamp structure which is engageable with a horizontal counter edge, or with a vertical post or partition edge. Where no such edge is available the clamping structure can be detached allowing the mounting base to be mounted directly on a vertical wall surface, e.g. by wood screws.

Abstract: The present invention includes a method for producing a chewing gum with a modified release sweetener selected from the group of N-substituted derivatives of aspartame, particularly neotame, as well as the chewing gum so produced. The modified release neotame or other N-substituted derivative of aspartame sweetener is obtained by physically modifying the sweetener properties by coating and drying. Neotame or another N-substituted derivative of aspartame sweetener is coated by encapsulation, partially coated by agglomeration, entrapped by absorption or extrusion, or treated by multiple steps of encapsulation, agglomeration, absorption, or extrusion. The coated sweetener is then co-dried and particle sized to product a release-modified high-intensity sweetener. When incorporated into the chewing gum, these particles are adapted to enhance the shelf stability of the sweetener and/or produce a modified release when the gum is chewed.

Abstract: A purge/clean system and an associated method for A fluid jet apparatus, such as an ink jet printing system, having a fluid chamber including a chamber wall having an exterior surface and at least one orifice through which fluid is ejected from the fluid chamber toward a substrate involves a cavity defined adjacent the exterior surface of the chamber wall into which fluid which is, expelled from the at least one orifice during a purging or cleaning operation is permitted to flow and a vacuum pump for withdrawing fluid which is contained within the cavity. The cavity can be provided by a plurality of plate arranged in an assembled, or stacked, relationship against the exterior surface of the chamber wall and, with the aid of a fan or compressor, can be used to create a zone of above -atmospheric pressure adjacent the exterior surface of the printer head. With the zone of above-atmospheric pressure created within the cavity, any leakage of air from the region into the atmosphere effects a flow of air out of the region and thereby helps to maintain the at least one orifice in a relatively clean condition.

Abstract: A needle protection device (2) for a vial (16) has a collar (4) at the base of which a number of finger grippers (6) extend. The collar (4) is placed about the hub (10) of a vial (16), and pushed there along until the gripper fingers (6) snap over the bottom surface of the needle hub (10) so as to fixedly couple the collar (4) to the needle hub (10) of the vial (16). Flexibly extending from the collar (4) is a housing (6) that is pivotable to a position in alignment along the longitudinal axis of the vial (16) for enveloping the needle (12), to thereby prevent the needle (12) from being exposed to the environment. A hook (18) integrated to the inside of the housing (6) ensures that the needle (12), the housing (6) could no longer move relative to each other once the hook (18) snaps over, and traps the needle (18), as the housing (6) is pivoted to its alignment position.

Abstract: An elongated fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into wall, floor, ceiling and roof cavities of different widths formed by the framework of a building. The blanket has one or more cuts extending for the length of the blanket which separate the blanket into two or more longitudinally extending sections. Adjacent sections of the blanket are joined together along the cut(s) by separable adhesive connectors which hold together the sections of the blanket for handling, but are separable by hand along the cut(s) so that the blanket can be handled as a unit for insulating a cavity having a predetermined width or easily separated by hand into two or more sections at a cut for insulating a cavity having a lesser width. The pre-cut insulation blanket may have a facing sheet, overlaying and bonded to a major surface of the blanket, that is separable by hand along the cut(s).

Title: Integrated process for producing "clean beef" (or milk), ethanol, wet distillers' grains with solubles, and bio-gas/bio-fertilizer
Inventor: HALLBERG DAVID E
IPC: A23K10/38
Filed: 2002-03-12
Granted: 2010-09-07
Abstract: An ethanol unit and anaerobic digestion/bio-fertilizer unit are integrated with a cattle feedlot (or dairy operation), wherein a continuous, balanced process yields a sanitary, low- to zero-pollution, and economically efficient production of "clean beef" (or milk), fuel ethanol, and bio-gas/bio-fertilizer. Fossil fuel consumption is substantially reduced, even eliminated, and 100% of the cattle waste is treated and converted into medium-BTU gas (bio-gas), organic fertilizer and bio-compost. The ethanol unit serves the dual purpose of ethanol production, as well as grain pretreatment to produce feed for the cattle. The grain is first processed in the ethanol unit, where the starch portion is converted into ethanol and CO2. The remaining concentrated protein portion (wet distillers' grains with solubles, or WDGS) is fed directly to cattle in "high saturation" (25% or more dry matter displacement). This change results in a superior ruminant animal ration, which displaces certain traditional feed components, alters the standard starch to protein ratio, and significantly improves conversion efficiencies and meat/milk quality.

Granted: 2007-10-30
Abstract: A pump has a housing defining a pump chamber and having a shaft opening. An impeller shaft extends through the shaft opening and is sized to define a ga p between the impeller shaft and the shaft opening. An impeller is attached to the shaft inside the pump chamber. The impeller includes a first set of impeller blades for transporting fluid through the pump chamber and a second set of impeller blades for creating a pressure force which pushes fluid away from the shaft opening. The pump with sealless shaft prevents fluid from leaking through the gap, and therefore is particularly suited for use in a tank-type vacuum cleaner capable fo collecting both dry material and fluid. The gap is used in such an application to prime the pump, thereby dischargin g fluid collected in the tank.
