Title: Arc preventing electrostatic power supply
Inventor: WEINSTEIN RICHARD
IPC: B05B5/10
Filed: 1991-12-31
Granted: 1995-04-11
Abstract: An arc preventing electrostatic power supply suitable for operating an electrostatic paint atomizer such as a rotary atomizer.  High voltage control is based on the high voltage current, as measured in the ground return path.  The power supply is controlled to provide a substantially constant high voltage DC output up to a predetermined current and an output voltage which rapidly drops off as the current increases above the predetermined current.  The magnitude of an AC component superimposed on the high voltage DC current is detected to determine incipient arcing.  Upon detecting an incipient arcing condition, the output voltage is interrupted for a predetermined short time.  When the output voltage is turned back on, it is ramped up from a low level back to the normal high voltage level.  While the output voltage is less than a predetermined low level, the sensitivity of the incipient arc detection circuit is increased.  The output voltage is again interrupted for the predetermined short time whenever an incipient arcing event is detected.

Title: Low calorie food products having smooth, creamy, organoleptic characteristics
Inventor: BAER CYNTHIA C
IPC: A23L29/231
Filed: 1990-08-16
Granted: 1996-10-01
Abstract: The present invention is directed to a method for preparing a low fat or substantially fat-free food product such as pourable dressings and viscous dressings. The method includes the steps of heating and repeatedly shearing at least two times an aqueous dispersion consisting of from about 3 to about 10 weight percent of microcrystalline cellulose and from about 90 to about 97 weight percent water.  The shearing occurs in a high shear zone having a pressure drop of at least 12,000 psi and the shearing is sufficient to fragment the microcrystalline cellulose to submicron sized microcrystalline cellulose fragments.  The microcrystalline cellulose fragments are reagglomerated under high shear conditions to produce an aqueous dispersion of porous, microreticulated microcrystalline particles having a void volume of at least about 25 volume percent, a mean particle size in the range of from about 5 to about 20 microns, and a particle size distribution such that at least about 75 weight percent of the particles have a maximum dimension of less than about 25 microns.  The microreticulated microcrystalline cellulose dispersion is combined with from about 2 to about 33 weight percent of xanthan gum, based on the dry weight of the microreticulated microcrystalline cellulose dispersion.  The xanthan stabilized microreticulated microcrystalline cellulose dispersion is then blended with additional food components to provide a low fat or fat-free food product.  The food product has from about 0.25 to about 4 weight percent of dispersed microreticulated microcrystalline cellulose, from about 50 to about 99 weight percent of water, from about 1 to about 35 weight percent of carbohydrates, from about 0 to about 10 weight percent protein, and less than about 7 weight percent triglycerides.

Title: High frequency electrical connector
Inventor: DENKMANN W JOHN
IPC: H01R13/6467
Filed: 1992-12-14
Granted: 1996-08-06
Abstract: An electrical connector for conducting high frequency signals includes a number of input and output terminals that are interconnected by a pair of metallic lead frames that are mounted on a dielectric spring block. The lead frames are identical to each other and comprise several flat elongated conductors, each conductor terminating in a spring contact at one end and an insulation-displacing connector at the other. The lead frames are mounted on top of each other and their conductors are all generally parallel and close to each other. Only three of theconductors of each lead frame are arranged to overlap each other; and this occurs in a designated crossover region without electrical contact being made because of a reentrant bend in the conductors in the crossover region. As a result, crosstalkbetween specific conductors can be reduced by judiciously choosing the location of the crossover and the particular crossover pattern.
