Granted: 1995-07-04
Abstract: A method and apparatus whereby livestock and poultry are administered feed additives in their feed ration.  The apparatus stores additive concentrates separately until just prior to use, then on demand dispenses the additive concentrates separately and sequentially into a partitioned weigh hopper for sequential, cumulative weighing therein.  The weighed contents of the weigh hopper are deposited into a liquid carrier within a mixing vessel where the dispensed additives are diluted, suspended, and dispersed by mixing.  The resulting carrier-and-additive slurry is pumped to a receiving station for mixing with a feed ration.  The weigh hopper is isolated from movements that would affect additive weight determinations during the weighing process so that accurate measurements of additive weights are obtained.

Title: Method for measuring surface temperature of sensors
Inventor: HORI TOMOSHIGE
IPC: G01N25/18
Filed: 1988-02-29
Granted: 1993-03-09
Abstract: ABSTRACT     A method for measuring the surface temperature of a sensor in heat-transferable contact with a subject fluid, employing an electrical heating method in which the surface temperature is measured while passing an electric current through an electrical conductor included in said sensor.  In this measuring method, the surface temperature is expressed as a function of a specific value inherent in the sensor, the amount of the electric current supplied to the electric conductor, and the temperature of the electrical conductor.  The sensor is heat-transferably contacted with another fluid whose physical properties are previously known, the surface temperature of the sensor in contact with such other fluid is determined by satisfying a mathematical relationship between the physical properties of the other fluid and the surface temperature, and the specific value inherent in the sensor is determined by using the calculated surface temperature.  The sensor is then placed in contact with the subject fluid and the surface temperature is measured by using the determined specific value inherent in the sensor. Thus, various physical properties of a fluid can be precisely measured, even if the theoretically determined specific value of the sensor is different from the actual specific value.

Abstract: Collapsible gridworks for confining fluent materials within cells defined by the gridworks to form stable columns capable of withstanding substantial vertical and horizontal loading are each made up of a plurality of interwoven/intermeshed longitudinal and latitudinal strips.  In the preferred embodiment, the strips include slots formed on alternating sides there-of, with the gridworks being formed by interweaving the slots on one side of the longitudinal strips with corresponding slots on the opposite side of the latitu-dinal strips such that the gridwork is defined by mechanically interlocking joints which permit motion for collapsing the gridwork into both a multilayer strip and a substantially flat sheet.  The open state of the gridwork and both of its collapsed states are similarly stable and can be freely handled without fear of the gridwork falling apart.  The strips may be extended in width to reinforce and stabilize stacked gridworks, with the widthwise extensions of the strips being slotted for such stacking.  The strips may also be extended in length beyond the outermost walls of the gridwork and slotted such that two or more of the gridworks can be interconnected to one another by interweaving the slotted length extensions of the longitudinal and latitudinal strips.

Title: Method and apparatus for decompressing encoded data
Inventor: LINEHAN FRANCIS P
IPC: H04N1/417
Filed: 1988-06-01
Granted: 1991-07-23
Abstract: METHOD AND APPARATUS FOR DECOMPRESSING ENCODED DATA      ABSTRACT OF THE DISCLOSURE A fast and flexible data decompressor decodes data, such as that encoded by CCITT Group 4 facsimile machines, to produce display data.  In the decompressor, a microprocessor controlled by microcode evaluates variable length codes each representing a series of data cells, each data cell in a series having a single value assigned thereto.  The variable length codes have a first code type, such as vertical codes and pass codes used in two-dimensional coding schemes, are decoded by the microprocessor.  The variable length codes having a second type, such as one-dimensional horizontal codes, are decoded by a pair of look-up tables in read only memories (ROM's). one ROM determines the length of the code and the other determines the run length of the series of data cells represented by the code.  A shifter which receives encoded data is shifted by the length of the code, whether determined by the code length ROM or the microprocessor. The microprocessor generates an intermediate code indicating the run length and the single value to be assigned to each of the data cells in the series of data cells, using the run length from the run length ROM if the code is of the second type.  The intermediate code is sent to a bit generator which generates a series of bits corresponding to the data cells.

Granted: 1994-11-15
Abstract: A siren detection system is particularly suited for installation in an automobile for providing a warning to the driver when an emergency vehicle is in the vicinity of the automobile. The system includes a microphone mounted on the automobile. The output of the mircophone is supplied to a bank of band-pass filters, each tuned to a different adjacent portion of the frequency range through which the frequency of a siren varies. The output of the filters are sampled by an averaging and selection circuit which produces a single output corresponding to the central one of any of the filters producing an output during a preestablished time interval. This output then is compared with the previous output (which indicates the previously selected band-pass frequency) to operate an up/down counter. Whenever successive counts of a preestablished number in the same direction occur, the output of the counter enables an alarm to indicate the presence of a siren operated by an emergency vehicle in the vicinity of the automobile. The system also includes circuits forenhancing noise rejection in the same frequency range.

Title: Method of, and apparatus for, wrapping articles in a plastic film
Inventor: VAN EIJSDEN CORNELIS
IPC: B65B11/12

Granted: 1992-06-09
Abstract: TITLE OF THE INVENTION:          A METHOD OF, AND APPARATUS FOR, WRAPPING ARTICLES IN A PLASTIC FILM                 ABSTRACT OF THE DISCLOSURE      A method of wrapping articles in stretch wrapping plastic  film and appropriate apparatus  for practicing this method are disclosed.  An article to be wrapped is surrounded by a plastic film by forming the film into a tube  around  the article  and sealing the longitudinal edges of the film in such a way that the tube does not contact the surrounded article.  The tube and article are then conveyed along the axis of the tube and at a point downstream from the tube sealing a portion of this tube is longitudinally stretched causing it to constrict on the  article.    The  stretching  tension  is  preferably isolated from the tube forming and sealing such that the tube may be formed in a continuous manner.  The stretched and constricted portion of the tube is closed in front of and behind the article being wrapped and then separated behind  the  wrapped  article.    Of  course,  either  the initial end of the tube or the separation behind the previous article provides a tube terminus in front of each article.   These tube terminuses may be clamped and heat sealed.    This  procedure  can  be  affected by  an  apparatus having means for supplying and discharging the articles to be wrapped, means for supplying the plastic film and forming it into a non-contacting tube about the articles to be wrapped and sealing the longitudinal edges of the tube,  means for stretching the tube in a longitudinal direction and means  for  separating the stretched and constricted tube portion from the unstretched portion.          The stretching operation is conveniently affected by a combination of a sleeve over which the tube passes and through  which  the  article  to  be  wrapped  passes,  a positive-transport  means,  such  as  rollers,  which cooperate with the outer surface of the sleeve to give the  tube  a  certain  forward  velocity  and  a  means downstream of the sleeve which can transport a portion of the tube downstream at a rate faster than the output of the positive-transport means.

Abstract: The invention relates to a foamed glass plate which has a dense glass surface layer on a foamed glass layer and which is useful as a building interior material or a furniture material.  The interface between the two layers is made wavy, and the dense glass surface layer is made transparent or translucent so that a wavy pattern can be seen through the dense glass layer.  For example, the interface is corrugated or rippled.  The foamed glass plate can be produced by the steps of layering a granular material of foam glass on a conveyor belt made of a heat resistant material, desirably waving the upper surface of the layered material, overlaying the waved surface with a layer of a granular or powdery material of dense glass and firing the materials in layers on the belt in a furnace.  The surface of the initially layered material can be corrugated by, for example, vertically oscillating the belt while the foam glass material is poured on the belt or can be rippled by pouring glass grains of suitably regulated grain size, as the material of the dense glass layer, onto a flat layer of the foam glass material.

Title: Apparatus for pressure molding ceramic articles
Inventor: HISAEDA MASANOBU
IPC: B28B13/06
Filed: 1989-03-01
Granted: 1993-08-03
Abstract: Abstract An apparatus for pressure molding ceramic articles is disclosed.  The apparatus includes at least one split mold consisting of a core mold and an outer mold which are joined together for defining a  pressure mold cavity therebetween.  At least the bottom surface of the pressure mold cavity is inclined longitudinally and laterally, while the split mold per se is not inclined and the slip supply passage for supplying the slip into the pressure mold cavity is communicated with the lowermost end of the pressure mold cavity. Due to the above construction, it is no more necessary to incline the entirety of the split molds so that the fame structure of the apparatus can be vertically constructed on a horizontal floor which permits easy co nstruction, installation and adjustment and maintenance of the apparatus. Furthermore, since the bottom surface of the pressure mold cavity is inclined longitudinally and laterally, the surplus slip is discharged completely and smoothly, and does not remain in the pressure mold cavity.  Accordingly, the molded articles of high-quality and uniform thickness can be obtained.
