Title: Liquid filter apparatus and method
Inventor: BRATTEN JACK R
IPC: B01D25/127
Filed: 1991-09-17
Abstract: LIQUID FILTER APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE    A pressurized liquid filter in which a series of spaced apart, vertically extending filter plates are mounted between the sides of housing, inflatable hose seals extending across each top entrance and bottom exit. Filter media strips are draped vertically into the spaces, each disposed over a perforated sheet forming the outer layer of either side of each filter plate.  The space between each pair of filter plates is subdivided into two filtering chambers by a dual element dewatering diaphragm mounted in a frame disposed centrally in each space.  Liquid slurry is introduced into each chamber under pressure, flow induced to pass through the filter media strips and passing into vertical passages in the filter plates and into collection troughs extending along each row of passages.  The filter media strips are held by carrier belts mounted on powered rollers at the top of each pair of filter chambers to enable the strips to be lowered out of the chambers when the hose seals are retracted after each filtering cycle, and thereafter again raised into position, being scraped and washed prior to being raised into the chambers preparatory to another filter cycle.

Title: Acoustic adiabatic liquid quantity sensor
Inventor: BATES KENN S
IPC: G01F22/02
Filed: 1991-10-22
Abstract: ACOUSTIC ADIABATIC LIQUID QUANTITY SENSOR   ABSTRACT OF THE INVENTION      An adiabatic liquid volume sensor system is described, which employs a main chamber in a back-to-back configura-tion with a reference chamber of known volume.  The system measures liquid volume in the main chamber by making low frequency acoustic measurements of the acoustic pressure differences in the two closed chambers when driven with a sinusoidal  frequency  from the  same  speaker.   Pressure transducers  in each chamber measure acoustic adiabatic pressures in each chamber.  The ratio of these pressures multiplied by the known volume of the reference chamber yields the volume of gas in the main chamber.  The volume of liquid is equal to the known volume of the main chamber minus the calculated gas volume.

Title: Formulations for oral administration, in particular to ruminants
Inventor: GREISSINGER DIETER
IPC: A23K40/35
Filed: 1992-01-14
Abstract: A formulation for oral administration, in particular to ruminants. Effective substances such as nutrients and medications should be released after a delay or slowly after they have been administered orally. In particular in the case of ruminants, very little or none should be released in the rumen. Suitable coatings are costly and, in particular, are unsuitable for administration in large quantities. Known coatings of this kind also entail the disadvantage of physiological incompatibility and/or are not permitted under current legislation. The new coating contains thinner zones and/or nominal break points that accelerate release compared to essentially even coatings. It is preferred that sharp-edged particles, such as pellets, be coated, when the coating is so configured that it can break away along the edges after oral administration. Preferred are coatings made up of two layers, the inner layer containing a filler and a film-forming medium, and the outer layer containing only film-forming medium.

Abstract: For the purpose of facilitating the impregnation of wood chips, the chips are compressed between two compression devices (9) which act on the mutually opposing flat sides of the chips (2). As the chips are compressed, the chips (2) are undulated or curved in at least one direction to produce a wave shape such that when the chips are seen in section at right angles to the waves, the top and the bottom sides (15, 16) of the wave crests will both be located on one side of a central plane (19) which passes through respective chips between the bottom sides (16) of the wave crests and the top sides (17) of the wave troughs, whereas the top and bottom sides (17, 18) of the wave troughs will both be located on the other side of the central plane (19). Apparatus for use in treating wood chips in this way includes compression devices (9) which present surfaces which are intended to act on the flat sides of the chip pieces (3) in a manner to form an undulating wave-shaped pattern which extends in at least one direction such that when in a chip-compression position the wave crests (13) on each compression device (9) will mesh with the wave troughs (14) defined by mutually adjacent wave crests (13) on the opposite compression device (9).

Filed: 1992-06-26
Abstract: 56,787 Abstract of the Disclosure A method for removing contaminated resin particles from soils.  The method entrains the resin particles and fines from the soil, which, due to the difference in specific gravity between resin and soil particles, results in a significant disparity between particle size of the entrained resin and the entrained fines.  This, in turn permits the fines to be screened from the resin and the larger soil particles, which have not been entrained, to settle out from the mixture.

Title: Photoelectrochemical imaging system
Inventor: TENCH D MORGAN
IPC: G03F7/20
Filed: 1992-11-02
Abstract: A method and apparatus are provided for photoelectrochemical reproduction of an image on a plate or roller. For a printing press, the apparatus includes a reusable image roller coated with a oxide semiconductor. A plating solution is applied to the image roller as a thin film. The desired image is written onto the oxide semiconductor by light illumination that generates a photoelectrochemical reaction between the semiconductor and the plating solution. In a preferred embodiment, the image roller is coated with hydrophilic p-type NiO. The image is written onto the roller as dots of oleophilic metallic copper, which are formed on the NiO coating by laser-generated catholic photoelectrodeposition. Subsequent erasure of the metallic copper image can be accomplished by chemical or electrochemical dissolution of the deposited copper. The method functions to create, erase, and recreate high-resolution images directly on a printing press roller without the necessity of precise matrix registration.
