Patent EP-0278187-A2 (EP)
Inventor: CHOU JAU-YI
IPC: G01G21/00
Filed: 1987-11-26
Abstract: A dual -range analog-to-digital convertor for the improved operation of an electronic computing scale provides significantly increased resolution in a first weight sub-range (0-12 pounds in the illustrative embodiment) and e coarser resolution in a second weight sub-range (11-100 pounds). The raw load cell voltage is communicated along first and second branches (27,30 ; 27,32), and subjected to a different trans­formation in each branch to produce first and second transformed voltages. In the first branch (27,30), raw voltages correspon­ding to weights in the low sub-range are mapped onto a desired sub-range of voltages. In the second branch (27,32), raw voltages corresponding to weights in the high sub-range are mapped onto a second sub-range of voltages. Depending on the weight on the scale, one or the other of the transformed voltages is applied through switch means (35) to the ADC input terminal (22), and the digital output is scaled accordingly. The circuitry includes a range flag (37) and logic circuitry (25) for sensing the digital ADC output, and controlling the range flag. When the range flag is in a first state (signi­fying that the low weight sub-range is selected) and the ADC output signifies a weight above the low sub-range, the range flag is set to a second state (high weight sub-range). Similarly, when the range flag is in the second state and the ADC output signifies a weight below the high sub-range, the range flag is set to the first state.

Abstract: An improved magnetic sealant is disclosed wherein the improvement comprises the introduction of magnetizable particles having a particle size of about 150 microns or larger into the resin. It has been found that the larger particle sizes allows for the introduction of increased amounts of magnetic particles into the resin without the loss of flow properties. This results in a sealant which will have strong magnetic properties but will be an effective sealant for irregular surfaces as well as smooth ones. Also disclosed is a method for making the sealant and a method for using it.

Abstract: A p.m. d.c. motor in which a stator is structured as a magnetically permeable base (114) upon which stator pole components (100) are mounted in upstanding fashion. Each of the stator pole components is formed as a laminar core (104) elongate rectangular shape about which a plastic bobbin (106) is slideably positioned. The field windings of the stator are wound about this bobbin to provide a structure having no flared tips or the like and wherein winding can take place on bobbins separately from the stator structure. A disk-shaped rotor (64) carrying a sequence of flat permanent magnets (130-133) is positioned over the tips of the stator components and is rotatably driven by select energization of the latter. Select skewing of the stator poles and design of the geometry of the permanent magnets functions to significantly reduce detent torque phenomena.

Abstract: Polymer materials having viscosities ranging from about 50,000 up to above 1,000,000 centipoises are mixed with a gaseous foaming agent to provide a polymer/gas solution under pressure such that when the polymer/gas solution is subsequently dispensed at atmospheric pressure the gas is released from the solution and becomes entrapped in the polymeric material to form a homogeneous polymer foam. Mixing is accomplished by force feeding the gas and polymeric material into and through a low energy input disk mixer (14) with a low pressure drop across the mixer such that premature foaming or reaction of the polymeric material is avoided. The disk mixer includes a tubular housing (22), one or more driven shafts (24, 26) extending along the length of the housing, and a series of disks (48) spaced along the shafts. The foaming gas enters into solution in the polymer in the compartments between the rotating disks. The process is characterized in that relatively high viscosity polymeric materials are mixed with gas and foamed with relatively low horsepower requirements, high throughput and low temperature rise of the polymer from conversion of the work of mixing to heat.

Abstract: This invention relates to a method for generating images by using a ray-tracing method. 
     In the case of the conventional method, a rectangular parallelepiped completely included in an object to be displayed is registered and subject to sampling although an intersection point between the ray and the object surface cannot exist there. 
     The method for generating images according to the invention registers only a cell containing surface 50 of object 44 among cells that are obtained by dividing region 42 containing object 44 to be displayed. The calculation of intersection points is performed only for rectangular parallelepipeds in which the surface exists. Thus, it is possible to reduce the time required for displaying object 44.

Abstract: The binary multiplier circuit for obtaining a product of a M-bit multiplier and a N-bit multiplicand includes a multiplier circuit which produces a matrix of original summand bits having M rows and M+N columns and a matrix reduction circuit. In the ma­trix reduction circuit, for every column of the matrix having three or more original summand bits, groups of three bits are input into full adder circuits which output a sum bit for that column and a carry bit for the column in the next most signifi­cant bit position. For every column having three or fewer origi­nal summand bits, and having the least significant column posi­tion that is not yet reduced to two or fewer bits, groups of two bits are input into a half adder circuit which outputs a sum bit for that column and carry bit for a column in the next most sig­nificant bit position. Iterative reductions are performed for each column by using full adder circuits for every group of three bits in a column and by using a half adder circuit for any re­maining group of two bits in a column. The reduction continues until each column of the matrix is reduced to two or fewer bits. The remaining two rows of bits can be input to a carry-propaga­ting adder circuit to output a sum equal to the product.

Abstract: An injection molding method and nozzle for use therein wherein first and second variable pressures are applied to a piston of a valve mechanism of the nozzle so that a differential fluid pressure on the piston causes a tip portion of the valve mechanism to alternately open and close. In this way, the tip portion communicates the flow of resin from a nozzle body of the nozzle to an injection aperture of a mold. Differential pressure on the piston prevents a fluid which distributes the molten resin over the interior surfaces of the mold from entering the flow path of the molten resin in the nozzle body. The fluid preferably is a gas, such as nitrogen. Preferably, the piston is mounted for reciprocating movement within the nozzle body and the first pressure is provided by the resin during resin injection and the second pressure is partially applied by the nitrogen gas. Preferably, the valve mechanism includes a counterbalance mechanism which is set to prevent fluid entry into the mold until the tip portion of the valve mechanism is closed. The resulting article is then cooled to a temperature below the softening point of the resin, the pressure is relieved within the article and the mold is opened to remove the article. The nozzle may also be utilized in making structural foam articles from a foamable resin. The pressure within the mold is relieved to permit foaming by the foamable resin after injection of the foamable resin.

Abstract: The invention relates to a process for the refining of a raw gas produced from a carbonaceous material by means of a gasification process, refining taking place in a secondary stage separated from the gasifier. In order to reduce the gas contents of tar in the form of organic compounds condensible at lower temperatures, such as ambient temperatures, and of ammonia, the refining is carried out in a secondary stage being a fast circulating fluidized bed, the bed material of which at least mainly being an active material in the form of a material that is catalytic for tar and ammonia conversion, whereby a catalytic conversion of tar and ammonia contained in the raw gas is obtained. In order to decrease the content of hydrogen chloride in the gas, an active material that also can absorb chloride is used. Fresh catalytic and absorbing material is supplied in an amount sufficient to have the hydrogen chloride present in the raw gas absorbed on the material, a corresponding amount of the material containing absorbed chloride being discharged from the secondary stage.
