Granted: 1991-02-26
Abstract: VERTICAL-WALLED EDGE-CONNECTED PANELIZED CONNECTABLE  RHOMBIC TRIACONTAHEDRAL BUILDINGS            ABSTRACT OF THE DISCLOSURE         A building system or combination of building structures which comprise panelized edge connected elongated rhombic tria-contahedral structures for the roofs and walls, the walls being elongated vertical panels.  The structures include hollow extruded connectors for joining the panels together and in some instances for joining the building structures together as a single unit.  Externally the connectors are relieved to provide a flush surface appearance with the panels.  The hollow connec-tors create strong lightweight structures with integral conduits for utilities.  Tie downs to retain the structures in place can be threaded through the hollow connectors.         One important optional feature is a foundation pro-vided by vertical panels partially buried in the ground.  This option provides a substantial improvement in the control of heat loss from the structures at minimum cost.  Another feature comprises optional alcoves creating a roof treatment minimizing the dome like appearance of the structures and substantially increasing the open interior floor space.  The alcoves and roof treatments utilize inverted connectors to form concave sections of the roof and exterior walls of the structures.

Granted: 1992-05-12
Abstract: UNITARY SPECIMEN COLLECTION TUBE                AND MICROSCOPE SLIDE DEVICE                          Abstract The device has a flat, elongated, self-supporting, preferably transparent backing strip and a transparent front strip bearing side and bottom flanges bonded to the backing strip.  Both strips are preferably plastic and the front strip is vacuum molded to a configuration which defines with the backing strip an upper open-topped hollow specimen collection tube for urine samples and the like and a lower microscope slide having an internal chamber. An intermediate, narrow bore, hollow conduit, preferably about 0.06 inch diameter, interconnects the slide chamber with the lower interior portion of the collection tube, so that sediment and the like can gravitate from the collection tube down through the conduit to the slide chamber.  The device can be centrifuged as an integral collector/slide unit and later the slide can be readily broken away from the collection tube at the conduit for microscopic analysis of the sediment therein.  Transverse score lines and/or notches permit the length of the collection tube to be adjusted to fit a centrifuge and facilitate breaking the slide away from the collection tube.  The device is simple, inexpensive and effective.

Granted: 1991-12-31
Abstract: APPARATUS COMPRISING A MONOLITHIC NONLINEAR FABRY-PEROT     ETALON, AND METHOD FOR PRODUCING SAME            Abstract The inventive method for forming monolithic nonlinear Fabry-Perot etalons comprises depositing on an appropriate substrate, e.g., a GaAs wafer, a first multilayer mirror, depositing on the first mirror a spacer typically comprising optically nonlinear material, and depositing a second multilayer mirror onto the spacer. Typically, at least one of the mirrors is an active mirror comprising optically nonlinear material. Deposition can be by a known process, e.g., by MBE or MOCVD. Since, inter alia, the method comprises no critical etching steps it can be used to produce high finesse etalons that have uniform properties over relatively large areas. The inventive method can be adapted to the manufacture of transmissive etalons. It can also be used to produce arrays of optically isolated etalons. Devices comprising nonlinear etalons manufacturedby the inventive method can be incorporated, for instance, into optical data processing apparatus, or into optical communications apparatus.

Title: Solid animal feed supplement and method for its production
Inventor: MILLER ALEX E
IPC: A23K10/40
Filed: 1987-06-15
Granted: 1994-06-21
Abstract: SOLID ANIMAL FEED SUPPLEMENT AND METHOD FOR ITS PRODUCTION                 ABSTRACT OF THE DISCLOSURE An acidic molasses-based liquid animal feed supplement  including nutritionally  appropriate  phos-phorus  and  magnesium  and,  optionally,  non-protein nitrogen, is hardened into a solid form by the addition of  a  small  amount  of  a  soluble  calcium  compound, preferably calcium chloride,  so that the calcium to magnesium weight ratio is between about 1.5 and 3.  The disclosed solid animal feed supplement is sufficiently palatable  to  permit  its  free  choice  feeding,  yet discourages overfeeding by its hardness and acidity. The block contains sufficient molasses to help meet the energy requirements for maintenance and weight gain of grazing  animals,  but is  sufficiently  low  in pH  to minimize the risk of ammonia poisoning due to breakdown of non-protein nitrogen sources to free ammonia during rumination.   The  solid  animal  feed  supplement  is prepared by mixing together two substantially homoge-neous liquid solutions, either or both of which contain molasses, but with one containing the soluble calcium compound and one containing the phosphorus compound, usually in the form of orthophosphate,  to provide a liquid mixture having an acid pH, preferably in the range below about 4.0 pH units.  In situ reaction of the magnesium, phosphorus and calcium compounds within this pH range quickly hardens the solution into a solid molasses block having a hardness of 80 or less in 0.1 millimeter penetrometer units.

Granted: 1992-05-26
Abstract: ABSTRACT         OPTICAL SIGNAL CONTROL METHOD AND APPARATUS   A method and apparatus for controlling the polarisation of an optical signal has many applications, including in coherent systems, eg heterodyne detectors.    Four birefringent elements (19, 21, 23, 25) in series are arranged to rotate the state of polarisation (SOP) alternately about orthogonal axes on a Poincare sphere.  A controller enables time varying initial and final polarisation states S, S' to be tracked.  It also ensures that the birefringence limits of the elements are never reached by carrying out an adjustment procedure.  A reduction by a full revolution (2.pi.) for one element (eg 19) can be achieved by varying the transformations of the other elements by not more than .pi..

Abstract: FORMATION OF THIN FILM SUPERCONDUCTORS      BY METALLO-ORGANIC DEPOSITION Abstract of the Disclosure Superconducting thin films of RE1Ba2Cu4Oz, where RE is a rare earth metal chosen from the group consisting of yttrium, ytterbium, and europium are produced in a non-vacuum environment using Metallo-Organic Deposition techniques.  A solution comprising the neodecanoates of the rare earth metal, barium, and copper is formed and spun on a single crystal substrate of strontium titanate.  The metallo-organic solutions are heated in an air environment at a temperature sufficient to decompose the neodecanoates, about 500°C, and then annealed to promote recrystallization and grain growth of the remaining metal oxides.  The annealing step is preferably accomplished using rapid thermal annealing techniques wherein the material is uniformly and rapidly heated to an appropriate temperature for an amount of time ranging between about instantaneous to about 2 minutes.  The resulting films of material exhibit superconductive characteristics at elevated temperatures.
