Title: Digital audio signal processing
Inventor: TOYAMA SOICHI
IPC: G01R23/16
Filed: 1990-11-19
Abstract: A digital signal processing device or DSP (2) outputs holding data in an output register (5, 6) in synchronism with a second clock pulse having a frequency lower than that of a first clock pulse for conducting arithmetic processing in the DSP. Accordingly, data to be output from the DSP can be directly read by a microcomputer (7), and contents in e.g. a coefficient memory and a delay time memory can be updated in accordance with the read data. The DSP can be applied to an audio apparatus such as a loudness controller which compensates for frequency-dependence of human auditory sensitivity, or a spectrum indicating apparatus which level-detects for some frequencies in turn and concurrently for other frequencies in turn. Another DSP has an input register to which either of two input ports can be selectively connected. <IMAGE>

Title: A retaining wall structure
Inventor: KNUDSEN POUL NYBOE
IPC: E02D29/02
Filed: 1990-12-28
Abstract: A retaining wall structure (1) for large-scale construction works, such as roads, railway tracks or quay constructions, where substantial amounts of earth or material are to be retained, and where said wall structure is constituted by panels. The wall structure comprises a front wall (2) and a rear wall (3) locked at a distance from said front wall by means of easily mountable crossbeams (4, 4'). The crossbeams are locked relative to one another in vertical direction by means of locking beams (5) so as to achieve a three-dimensional structure with interconnected and locked panels, filler (8) being filled into the space between the front wall and the rear wall. As a result, a retaining wall structure is obtained which is internally locked in three dimensions and capable of withstanding both tensile and pressure stresses. Furthermore, the retaining wall structure can be built by unskilled construction workers.

Title: Liquid dispensing guns
Inventor: ROLLINS VICTOR
IPC: B05C17/005
Filed: 1991-04-30
Abstract: Pistol-grip-operated liquid-dispensing guns incorporate a strong spring 3 to provide oven flow of the dispensed liquid and, in the case of two-part (or multi-part systems), constant metering of the component parts, even between successive cartridge pressurisations accomplished by the operation of the pistol-rip. The springs are inserted either between the cartridge and the frame of the gun (Figs 3, 5), or between the cartridge and the pressurising piston(s) (as shown). The compression of the springs when the gun is used maintains a relatively constant pressure on the cartridge, smoothing the liquid flow. <IMAGE>

Title: Four wheel steering system
Inventor: IZAWA MASATAKA
IPC: B62D113/00
Filed: 1991-11-28
Abstract: A four wheel steering system for a motor vehicle with steerable front and rear road wheels comprises a steering angle sensor 14 for detecting a front wheel steering angle through which the front road wheels are steered, a vehicle speed sensor 19 for detecting a vehicle speed of the motor vehicle, and a controller 20 for controlling the rear wheel steering mechanism to steer the rear road wheels based on the detected front wheel steering angle and the detected vehicle speed when the front road wheels are steered. The controller 20 controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is opposite to the front road wheels if the detected vehicle speed is relatively low, and also controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is the same as the front road wheels if the detected vehicle speed is relatively high. Furthermore, the controller controls the rear wheel steering mechanism to increase a rear wheel steering angle with which the rear road wheels are steered as the front wheel steering angle increases if a change in the front wheel steering angle is relatively small, and controls the rear wheel steering mechanism to reduce an increase in the rear wheel steering angle if a change in the front wheel steering angle is relatively large. <IMAGE>

Title: Hydrostatic pressure responsive device,e.g. for releasing a life raft
Inventor: WIGRAM RICHARD INGE
IPC: B63C9/22
Filed: 1993-10-22
Abstract: A hydrostatic pressure responsive device for releasing a life raft or the like when a ship sinks has a flexible diaphragm 13 sealing a chamber 10 on one side and exposed externally on its opposite side. A ceramic vent plug 30 is mounted on the diaphragm so that it is protected within the casing of the device. The diaphragm has a resilient plate 14 with an integral sleeve 24 that projects through a collar 21 in rigid disc 16 mounted on the plate. The plug 30 is retained within the sleeve 24, in the collar 21. A rod 18, 19 projecting from the diaphragm 13 extends into one end of an aperture 41 in a slider 40 and locks it it in position. When the device is submerged, the diaphragm 13 is deflected and pulls the rod out of the aperture allowing the slider 40 to be released from a notch 70 in a bolt 7 which may be connected to a life raft etc. A button 60 on the slider extends into the other end of the aperture 41 so that when it is depressed it pushes the rod 18, 19 out of the aperture and releases the slider. <IMAGE>

Title: Chimneys and flues
Inventor: SHUTE JOHN SIDNEY
IPC: F23J13/04
Filed: 1994-01-21
Abstract: Chimneys and flues are made up of blocks each having a passage therein which, in the finished chimney or flue, define the flue passage. The blocks are automatically aligned by providing each block with a projecting rim 16 around the flue passage at one side of the block and a recessed shoulder at the other side. The rim 16 of one block fits into the shoulder of the adjacent block and a compressible preformed sealing gasket 20 is positioned round the rim 16 before the blocks are placed one on top of another. The gasket is of a thickness greater than the rim height before compression, and is compressed to a thickness less than the rim height in use, but not so much that the gasket takes the full load between the blocks. <IMAGE>

Title: Photosensitive derivatives of ATP as assay control standards
Inventor: SIMPSON WILLIAM JOHN
IPC: C12Q1/66
Filed: 1994-04-06
Abstract: There is disclosed the use of a photosensitive derivative of adenosine triphosphate (ATP) for use in the bioluminescent assay of ATP. The derivative may be caged-ATP e.g. nitrophenol ester of ATP which contains a photohydrolysable ester bond. The sample which is being assayed for ATP is mixed with a reagent containing luciferin-luciferase and a known quantity of caged-ATP and the light emitted is measured. The mixture is then exposed to a flash of intense light resulting in the release of ATP in a photolytic reaction. This ATP reacts with the firefly luciferase to emit light, thus allowing the amount of the sample ATP to be deduced. The method overcomes problems with contaminated or unstable standard solutions of ATP.
