Title: SIMD processor circuit for performing iterative SIMD multiply-accumulate operations
Inventor: WILDER MLADEN
IPC: G06F15/80
Filed: 2008-10-08
Abstract: Disclosed is a circuit for performing SIMD multiply-accumulate operations, the circuitry is responsive to control signals to process data in parallel on multiple data elements. Instruction decoder circuitry is coupled to the data processing circuitry and generates the control signals from program instructions. The input to the instruction decoder circuitry is a single instruction (a repeating multiply-accumulate instruction) having as operands a first vector of input data elements, a second vector of coefficient data elements, and a scalar value indicating the number of the iterations required. The SIMD data processing circuitry performs the required number of iterations of the multiply-accumulate process, each iteration involving performance of N multiply-accumulate operations in parallel in order to produce N multiply-accumulate data elements. For each iteration, the SIMD data processing circuitry determines N input data elements from said first vector and a single coefficient data element from the second vector to be multiplied with each of the N input data elements. The N multiply-accumulate data elements produced in a final iteration of the multiply-accumulate process are then used to produce N multiply accumulate results.

Title: Electronic starting circuit for single phase AC motor
Inventor: LU CHUPING
IPC: H02P1/16
Filed: 2008-10-22
Abstract: A starting circuit, suitable for a single-phase AC motor comprising a main winding 1 and a starting winding 6, comprises a current detecting circuit 2, a rectifying and filtering circuit 3, a triggering circuit 4 and a switching circuit 5. The current detecting circuit 2 is connected in series with the main winding. The switching circuit 5 is connected in series with the starting winding 6. The rectifying and filtering circuit processes the detected current signal and operates the triggering circuit 4 via an optically coupled bi -directional silicon controlled rectifier, IC1. The triggering circuit enables or disables the switching circuit according to the detecting current, so as to energize or de-energize the starting winding. The starting circuit, which replaces a conventional centrifugal switch in capacitor start motors, features high reliability, long lifetime, simple circuit structure, low cost, and small size and finds application in motors for refrigerators, freezers, washing machines, dryers and fans.

Abstract: A quaternary ammonium hydroxide is produced from the corresponding bis-quaternary ammonium sulphate by electro-dialysis in a three compartment cell in which an aqueous solution of sulphuric acid of concentration 0.05 to 3.0 N is circulated through the anode compartment, an aqueous quaternary ammonium hydroxide solution of concentration 0.1 to 1.0 N is circulated through the cathode compartment, and an aqueous solution of the bis-quaternary ammonium sulphate is circulated through the central compartment which is separated from the anode compartment by a strongly basic anion exchange resin membrane and from the cathode compartment by a strongly acidic cation exchange resin membrane; the applied voltage being such as to provide D.C. at a cathode current density of 0.05 to 1 amp/cm2, the product being obtained by withdrawing a portion of the circulating catholyte.  Typically the quaternary ammonium groups in the sulphate are formed by C1 to C4 alkyl groups and the concentration of the sulphate solution is from 20 to 60 weight %, while the product is withdrawn as a 2 to 20 weight % solution. The cathode may be of stainless steel, the anode may be of lead containing a small amount of silver and the ion exchange resin membranes are formed of styrene-divinyl benzene copolymer on a glass cloth backing, the anion exchange resin being formed by quaternizing the copolymer and the cation exchange resin being formed by treating the copolymer to attach sulphonic or carboxylic acid groups to it.

Abstract: Fertilizers are produced by subjecting aqueous calcium chloride lyes, such as the waste calcium chloride liquors of ammonium soda works, to double decomposition with ammonia and carbon dioxide or with ammonium carbonates and transforming the reaction mass without separation of its constituents into a dried product consisting substantially of calcium carbonate and ammonium chloride.  The reaction may be carried out under pressure. Instead of ammonia or carbon dioxide, gas mixtures, e.g. gases from the distillation of coal, coke-oven gas, flue gases or combustion gases, containing one or both of these constituents, may be used for the double decomposition.  When such gas mixtures are employed care is taken to remove therefrom such constituents, e.g. cyanogen and hydrogen sulphide, as would produce products injurious to plants.
