Title: Grinding machine with reciprocating abrasive bolt
Inventor: TRUFITT MARK
IPC: B24B21/00
Filed: 1989-11-23
Abstract: In a reciprocating belt grinding machine for grinding cam profiles around the periphery of a swash plate, accurate grinding of the surfaces depends upon constant use of fresh abrasive, constant belt tension, and no wear of the profiled former around which the abrasive belt is driven. A tensioning arrangement is provided comprising a block 17 with an adjustable weight 18 supported by the abrasive belt 19. The belt engages the rims of a pair of wheels 20 which can be rotated by means of a handle 25 connected to a third wheel 24 which engages the first two wheels. Rotation of the handle 25 results in rotation of the belt-engaging wheels 20 and advances the abrasive belt. Wear on the profiled former is minimised by providing a metal strip intervening between the oscillating abrasive belt and the former. The strip itself could be provided on a spooling arrangement such that it could be advanced as wear occurs. The handle advance mechanism for the belt could be automated to index the belt at predetermined intervals. <IMAGE>

Title: Animated ornament
Inventor: KIM DOUGLAS TAEK
IPC: A63H29/22
Filed: 1990-04-11
Abstract: An animated ornament, such as a butterfly, has oppositely disposed wings or wing-like members (e.g. elephant ears) alternately raised and lowered.

Title: Automatic frequency control circuit
Inventor: MAEDA HIDENARI
IPC: H04B10/64
Filed: 1991-01-14
Abstract: An automatic frequency control circuit provides two power control circuits 16A, 16B for each of two frequency detectors 18A, 18B to regulate signal powers of input intermediate frequency signals IF1, IF2, and detects whether the signal powers satisfy minimum signal power. Further, this automatic frequency control circuit selects one or both of the input intermediate frequency signals in response to the detection. The automatic frequency control circuit controls a light source driver circuit 32 using a voltage signal which is generated by frequency-voltage conversion of the selected intermediate frequency signals. The circuit may be used for coherent diversity reception, and the driver circuit 32 may drive a laser diode module. The intermediate frequency signals may be generated from light signals with different polarity transmitted in an optical fibre. <IMAGE>

Patent GB-2267947-A (GB)
Title: Controllable motion-damper
Inventor: REECE MICHAEL PETER
IPC: F16F9/53
Filed: 1992-06-17
Abstract: A damper far railway vehicles, comprises two 'rubber' bellows (7) connected by a nozzle (1). The nozzle consists of a tapered orifice in the form of two conical bores, apex to apex, diverging from a common cross-section (3), this unit being completely full of a damping fluid (9) which consists of soft-iron particles suspended in oil or hydraulic fluid. This whole unit extends between two fluid containers (8, 10) which are compressed differentially from a double acting master cylinder (19). Such differential pressure causes one bellows (7) to be compressed and the other to expand so pumping the damping fluid through the nozzle (1) and exerting a damping force, which is controlled by the current supplied to a coil (5). In an alternative device, the damper is mounted in a piston (Fig. 3). <IMAGE>

Filed: 1992-08-14
Abstract: A method of testing for contaminating mineral oil in a sample of synthetic ester lubricating oil from mechanical vapour recompression type heat transfer equipment which is to be retrofilled with hydrohalocarbon working fluid, comprises mixing a predetermined quantity of the synthetic ester lubricating oil with a predetermined quantity of a polar liquid or a mixture of polar liquids and determining whether the resulting mixture is clear or turbid, a clear mixture indicating that the concentration of contaminating mineral oil in the synthetic ester lubricant is below the maximum tolerable concentration and that the system can therefore be safely retrofilled with the hydrohalocarbon working fluid; and a turbid mixture indicating that the concentration of contaminating mineral oil is above the maximum tolerable concentration and that the system must therefore be reflushed with synthetic ester lubricant to further reduce the mineral oil contamination. A test kit for the procedure is also disclosed.

Title: Compensating for linear distortion in loudspeakers
Inventor: RHEE WON-WOO
IPC: H03G5/00
Filed: 1994-06-29
Abstract: The distortion compensation apparatus heightens resolution of the low frequency domain and relatively lowers the resolution in the higher frequency domain. By performing band division using a Bark scale, filter coefficients are determined. The acoustic signal of the whole audible frequency band which is not filtered by a low-pass filter is distortion-compensated by means of a first filter portion. The acoustic signal of the divided band (which is obtained by low pass filtering) is filtered by a second filter portion so as to remove a portion of the distortion which has not already been compensated for by the signal distortion compensation of the whole audible frequency band. Then, the filtered signal of the divided band is added to the distortion-compensated acoustic signal of the whole audible frequency band. In this manner, the remaining signal distortion portion in the distortion compensated acoustic signal produced by the first filter portion is removed by the signal output from the second filter. This method allows the use of shorter FIR filters. <IMAGE>
