Title: Polyester backed acrylic composite molded structure
Inventor: KUSZAJ KARL T
IPC: B32B7/00
Filed: 1990-05-11
Granted: 2000-07-11
Abstract: A polymeric composite structure having a configuration of a bathtub and a process of manufacturing the structure is disclosed. The polymeric composite structure includes an acrylic shell (12) and a plastic molded backing layer (14) which is bonded to a non-finish side (21) of the acrylic shell. A fiber reinforced resin layer, preferably fiberglass, is adhered to the non-finish side of the acrylic shell. A weight bearing reinforcing structure (16), such as chip-board, is adhered to the non-finish side of the shell (21) and to the fiber reinforced layer embedded within the molded polymeric backing layer. The molded polymeric backing layer (14) is made from a cross-linked thermosetting polymer, preferably a polyester blend, which does not contain isocyanate. The backing is bonded to the non-finish side of the shell and surrounds the fiber reinforcing and weight bearing reinforcing structures (16). The fiber reinforcing layer is bonded to the shell by a silane based coupler. The backing layer also includes a curing promoter, a peroxyde cross-linking promoter and a filler such as calcium carbonate, sand or other fillers. The composite structure is manufactured by a, process which includes preforming an acrylic shell, reinforcing a non-finish side of the acrylic shell with a resinous mixture of reinforcing fibers by spray-up and roll-out techniques and arranging the reinforced shell in a mold with a non-finish side covering a reinforcing structure placed below the floor of the shell. An uncured mixture of the thermosetting polymeric backing and promoter is injected into the mold coating the non-finished side of the shell and covering reinforcing fibers and chip-board structure. The thermosetting backing material is cured sufficiently to permit demolding of the composite structure without damage. The shell is preferably primed with a silane based coupler prior to the reinforcing step. In an alternative manufacturing process, the spray-up reinforcing step is replaced by the placement of a fiberous mat within the mold, surrounding the non-finish side of the shell. The fiberous material may include a fiberglass woven or a mat material or it may include a preformed fiberous structure.

Abstract: Object spaces which mechanize higher order relationships between attributes which describe a particular problem domain. An abstract object description defined by a set of attributes and their corresponding values is transformed into a mixed-resolution, N-dimensional object space. The mixed-resolution, N-dimensional object space represents a mechanized, logically encoded expression of attribute relationships that can be visualized. The method and apparatus interleave the frame to generate an object descriptor and generate from the frame and the object descriptor, encoded names of spatial locations for each of the N dimensions of the mixed-resolution, N-dimensional, object space, conforming to a primary form of a reflected binary code. A virtual image of the N-dimensional, object space is generated from the dimensional-spatial locations and resolution-spatial locations, and attribute values corresponding to a region of the virtual image may be selected for display.

Title: Fluid urea-containing fertilizer
Inventor: WESTON CHARLES WITTMANN
IPC: C05G5/23
Filed: 1994-10-11
Granted: 2005-12-27
Abstract: An improved fluid urea-containing fertilizer composition is disclosed; the composition is essentially comprised of an aqueous solution of urea, ammonium nitrate, N-(n-butyl)thiophosphoric triamide (NBPT), dicyandiamide (DCD), and may optionally also contain a clay as a suspending agent. The fluid fertilizer composition can be applied to a field crop in a single application and will nevertheless supply sufficient nitrogen to the plants throughout their growth and maturing cycles. As a result, the improved composition increases the nitrogen uptake efficiency of plants, enhances crop yields, and minimizes the loss of nitrogen from the soil. The NBPT is incorporated into the fluid fertilizer composition by blending a concentrated solution of N-(n-butyl)thiophosphoric triamide in a solvent selected from the group consisting of liquid amides such as an N-alkyl pyrrolidone directly with an aqueous solution of urea and ammonium nitrate, optionally also containing a suspending agent and commonly referred to in the fertilizer trade as UAN; the DCD may be added to the UAN fluid as a solid, a suspension, or in dissolved form along with the NBPT.

Title: Method and apparatus for verifying proper wiring of brake pressure modulators
Inventor: MORAN STEPHEN P
IPC: B60T8/36
Filed: 1993-04-01
Granted: 2002-11-12
Abstract: A test for an electronically controlled braking system, such as an adaptive braking system, is made to assure that the solenoids of each of the modulators (52, 54, 66, 68) are properly wired. According to the test, each modulator (52, 54, 66, 68) is tested in sequence. The exhaust solenoid of a modulator (52, 54, 66, 68) is actuated for 10 milliseconds, and the hold solenoid is then actuated for 30 milliseconds. If the modulator (52, 54, 66, 68) has been miswired, the exhaust solenoid will have been actuat-ed for 30 milliseconds, thus generating a much louder "popping" sound than that generated by the other modulators (52, 54, 66, 68) will be imme-diately noticed and corrected.

Title: Method of increasing egg production in avian species by active immunization against vasoactive intestinal peptide
Inventor: HALAWANI MOHAMED EL
IPC: A61K39/00
Filed: 1993-09-22
Granted: 2005-01-04
Abstract: The present method of increasing egg production in laying turkey hens includes actively immunizing the hens with vasoactive intestinal peptide. The peptide is conjugated to a protein to induce an antibody response in the hens. The resulting antibodies tie up vasoactive intestinal peptide naturally produced in the turkey. This lack of naturally produced VIP in the turkey in turn prevents the secretion of the hormone prolactin from the pituitary gland of the hens to eliminate the onset of broody behavior. The hens are immunized prior to the laying season and subsequently boosted with immunizations approximately once per month during the laying season.

Abstract: A photonic switching method and a photonic switch utilizing same are disclosed.  Input electrical signals Ea ? Ed input through plural input ports 21a ? 21d are converted into optical signals with the pulse intervals of these input electrical signals being unchangedly preserved.  The converted optical signals are timing adjusted within the pulse interval and multiplexed in such a manner that these optical signals are not overlapped with each other on an axis of time.  The resulting multiplexed optical signal L is transferred to each output ports 19a ? 19d, respectively.  An optical signal, among the multiplexed optical signal L, which should be output at a target output port in each output ports 19a ~ 19d is separated by utilizing an opto-optical interactional function, for example, a four optical wave mixture.
