Title: A transform processing circuit
Inventor: HUA KIEN THANH
IPC: G06F7/48
Filed: 1988-08-22
Abstract: The elements (36, 38, 40) of a transform processing circuit (30) are switchable to change the order of data in a data stream and/or to perform a fast Fourier transform (FFT) or inverse fast Fourier transform (IFFT) on the data stream. Each arithmetic circuit element (36) performs an M-point butterfly operation on complex sample points and includes an adder/subtractor (44) and a serial memory (46) capable of storing M/2 sample points. Each multiplication unit (38) performs an n-point complex twiddle factor operation on its input. The conjugator units (40) conjugate inputted sample points. All circuit elements (36, 38, 40) are connected to buses (42) by switches. These connections are switchable so that in one switch state data input at left terminal (32) flows to right terminal (34) and in another state data input at right terminal (34) flows to left terminal (32). The state of the bus switches also determines whether the circuit performs an FFT, an IFFT, or a bit reversal operation on input data. Transfer processing circuit (30) may be incorporated into an integrated circuit together with a complex multiplier and a multiplexer, the integrated circuit is capable of performing FFT and IFFT operations on vectors or on transformed vectors and is capable of performing vector multiplication.

Filed: 1990-04-27
Abstract: The method is applied in the paper industry. A cyclic process is acquired by means of phosphogypsum re-crystallization ,a fine-disperse product in ordinary conditions is separated directly without grinding. By this method, the initial phosphogypsum is treated with a 40-50 percent solution of ammonium sulphate. The result of this interaction is a binary salt, which is filtered and decomposed with water and/or rinsing waters, containing up to 10 percent weight of ammonium sulphate, the ratio being solid phase / liquid phase from 1:1 to 1:2.5 at a temperature from 20 to 70 degrees C for 10 to 40 minutes. The rinsing waters used, have up to 10 weight percent of ammonium sulphate. The suspension obtained is filtered, the separated solid phase of the phosphogypsum is rinsed with water. The filtrate , containing up to 10 percent weight of ammonium sulphate is returned for repulpation of the binary salt. The filtrates from the separation of binary salt and phosphogypsum are combined and returned to the technological cycle for processing of new quantities of initial phosphogypsum.

Title: Rotatable handle with reverse angle and controls
Inventor: ABBOTT KENNETH E
IPC: B24C5/02
Filed: 1989-10-04
Abstract: ROTATABLE HANDLE WITH REVERSE ANGLE AND CONTROLS         An improved pressure hose handle which freely rotates around the pressure hose and is supplied with a "reverse angle" grip to facilitate use and reduce operator fatigue as well as an operator input panel.  The reverse angle, when combined with the rotational ability of the handle, permits the operator to carry the hose either over the shoulder or at waist height.  The over the shoulder mode places the weight of the hose upon the operator's legs and thereby reduces fatigue and gives the operator greater control.  The operator input panel permits the "fine tuning" of the blast to adjust for changing blast requirements as the substrate material changes.  Since the operator has complete control of the blasting parameters, the risk of damaging the substrate or target is minimized.

Title: Tilt-compensation system suitable for use in conjunction with high speed vehicles, more particularly rail vehicles
Inventor: SCHNEIDER RICHARD
IPC: B61F5/24
Filed: 1989-10-13
Abstract: ABSTRACT            A device suitable for compensating during high speed curve travel for the tilting of a car body of a rail vehicle employs a passive tilting system comprising a tilt compensator which, during travel over cambered, curved track compensates for the tendancy of car body to tilt toward the outside of the curve. The proposed tilt compensator features a four-bar linkage which, in concert with an energy storer, causes the car body to tilt to the inside of the curve.  In this arrangement, the car body rests on an auxiliary transverse suspension and readily adapts, without any reduction of its contour in response to transverse tilting, to a prescribed boundary profile. The present invention thus provides, during curve travel, for compensation of the tendancy of a car body to tilt to the outside of a track curve and, furthermore, aided by an energy storer, serves to translate such outward tilting motion into a tilting motion toward the inside of the curve.

Abstract: HIGHLY EFFICIENT METHOD FOR CALCULATING ROTATIONAL SPEED         Abstract of the Disclosure A process for maximizing the instruction processing efficiency of a digital computer for the purpose of calculating rotational speed wherein the calculation of speed is based upon speed signals generated by a tachometer.   By (1) counting the quantity of the speed signals received during a fixed sampling period, and (2) recording the occurrence time of these speed signals only as necessary for the calculation of rotational speed, the invention improves over known methods in that it does not record the occurrence time of all speed signals, but rather records the occurrence time of only those speed signals necessary for the calculation.  The invention accomplishes this by a) anticipating when the speed signals necessary for the speed calculation will be generated (and subsequently received by the digital computer) and b) recording the occurrence times only when it is anticipated that these necessary edges will be received by the digital computer.
