Title: Improved anaerobic fermentation method and apparatus
Inventor: COULTHARD LOUIS CHRISTOPHER
IPC: A01F25/16
Filed: 1985-07-19
Abstract: The present specification describes an apparatus (2) for and a method of anaerobic fermentation of organic waste material capable of being biodegraded into useful gaseous products. In one form the apparatus (2) consists of a double tank (8, 18) arrangement having a flexible membrane (10) or a cover securely attached to the top of the tank to collect the gaseous products. The flexible membrane (10) permits the volume of the gas being collected to vary whereas the double tank arrangement (8, 18) defines a tortuous path for the organic waste material to allow sufficient time for the fermentation to take place.   <IMAGE>

Title: Production of bodies of revolution having at least one groove
Inventor: BALINT LUDWIG
IPC: B21H1/18
Filed: 1985-10-18
Abstract: Bodies of revolution are produced having at least one peripheral groove whose width decreases towards the floor of the groove by rotating a blank 9 about its longitudinal axis while a pressure which exceeds the yield point of the material of the blank is locally applied. To avoid excessive hardening of the blank material during shaping, pressure on the blank is reduced from a maximum corresponding to the width of the groove at the peripheral surface of the blank, to the width of the floor of the groove, in accordance with the progressing depth of impression X1 to X5. The blank is rolled between ribs on a central roller (12, Figure 18) and ribs 7 and 8 on die segments 2 to 6. The initial portion of each rib is axially wide but radially shallow and the radial height of the ribs increase while their width decreases. <IMAGE>

Title: Improvements in or relating to material testing apparatus
Inventor: BARKLAM ALAN
IPC: G01N3/04
Filed: 1986-01-14
Abstract: Ceramic extensometers 10, 12, are used to transfer the movement of a test specimen [20] which is brought about by the application of heat and/or load thereto,to a transducer 62, in known manner. Conventionally the lower portions of the extensometers 10, 12 are supported from the load applying structure 22 via leaf springs but such an arrangement results in forces being generated which act laterally of the extensometers 10, 12 and sometimes results in their breakage. To obviate this disadvantage the power portions of the extensometers 10, 12 are supported from structure 22 by a rectangular arrangement of yokes and coil springs which obviates the lateral loads. Support for extensometer 10, which is similar to that for extensometer 12 is provided by a yoke 44 secured to a U-shaped bracket embracing the extensometer, and a pair of coil springs 56, 57 extending between the ends of the yoke and rods 52, 53 projecting from the vertically movable pillar structure 22. <IMAGE>

Title: Particulate material dispenser
Inventor: SEFTON KEITH
IPC: G01F13/00
Filed: 1987-02-07
Abstract: A device for dispensing particulate material into cups for subsequent use in a vending machine has two dispensing nozzles (34), through a cylindrical bore of each of which passes a respective screw auger (42) having a disc (50) secured to its lower end. The exterior of each nozzle (34) is shaped to receive a cup (54) whose upper rim is adapted to abut substantially sealingly against a shoulder (58) provided on the nozzle. The cups (54) are liftable into engagement with the shoulders (58) around the nozzles (34) by means of pneumatic jacks (56) situated beneath the cups. In use, a conveyor (22) advances the cups stepwise so that each in turn is situated beneath a nozzle. The jacks (56) are then actuated to position the cups (54) around the respective nozzles (34) with the upper rims of the cups in contact with the respective shoulders (58) on the nozzles. Rotation for a predetermined time of the augers (42) causes a metered amount of particulate material to be advanced along the cylindrical bores (38) onto the discs (50), from which the material is thrown-off by centrifugal force. <IMAGE>

Title: Linear interpolation method
Inventor: TREVETT NEIL FRANCIS
IPC: G06T15/10
Filed: 1988-03-23
Abstract: A method of linear interpolation over a line having a given length comprising the steps of initializing the multiplier accumulators output registers with predetermined initial values 410, 412 [e.g. with the initial rounding value and the starting value for one of the coordinates (e.g. Y), respectively]; loading a first input register 402 of the multiplier accumulator with a value equal to the incremental change (e.g.  DELTA Y=5) in the output value over the length of the line; loading a second input register 404 of the multiplier accumulator with a value (1/N) equal to the reciprocal of the length of the line (N); causing the multiplier 406 to multiply the values (eg  DELTA Y and 1/N) at its first and second inputs; accumulating the fractional part of the result of the multiplication in a first output register 410; accumulating the interger part of the result of the multiplication added with the overflow of the first output register in a second output register, 412, whereby and accumulated result is formed. The overflow is accumulated in a third output register, 414, and overflows to the integral register. For Gouraud shading of a line, one of the input registers is loaded with colour change along a line and the other with reciprocal of line length. An output register, 412, is initialised with a start colour. <IMAGE>

Abstract: 900,020. Sound reproducing circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 20, 1959 [Nov. 24, 1958], No. 39464/59. Class 40 (4). A switch connects the two pre-amplifiers of a stereophonic amplifier to function as an oscillator, oscillations being fed in equal magnitude to both channels. A double-pole switch 1, Fig. 1, in one position interconnects the grids and anodes of valves 2, 4 to provide a symmetrical relaxation oscillator and in its other position connects the valves, functioning as pre-amplifiers, to stereophonically related inputs. The oscillator provides symmetrical square wave signals of frequency 1000 c/s. and permits aural comparison of the two channels, balance being obtained by volume control 10. One channel may be a complete amplifier and loud-speaker and the other may consist of a preamplifier only for feeding an A.F. amplifier. The amplifying elements are pentodes or transistors. The switch 1 may be a multiposition input switch, Fig. 2, not shown.

Title: Error protection for multi-pulse speech coders
Inventor: ZINSER RICHARD LOUIS
IPC: H04L1/00
Filed: 1990-11-21
Abstract: Protection of a digital multi-pulse speech coder from fading pattern bit errors common in a digital mobile radio channel is accomplished by employing a synthetic regeneration algorithm which uses only the perceptually significant bits in the transmitted frame. Separate parity checksums for line spectrum pair frequency data, pitch lag data and pulse amplitude data are added to each frame of speech coder bits in the transmitter. The bits are then transmitted through a mobile environment susceptible to fading that induces bursty error patterns in the stream. At the receiving station, the parity checksum bits and speech coder bits are used to determine if an error has occurred in a particular section of the bit stream. Detected errors are flagged and supplied to the speech decoder. The speech decoder uses the error flags to modify its output signal so as to minimize perceptual artifacts in the output speech. <IMAGE>
