Patent GB-2282337-A (GB)
Title: Treating organic waste in an anaerobic digester by passage through perforate channel
Inventor: REYNELL CHRISTOPHER PAUL
IPC: C05F17/00
Filed: 1993-08-14
Abstract: Apparatus for treating organic waste comprises a reception hopper 3 for receiving the waste, a vessel 1 within which anaerobic digestion can be carried out, a pipe 2 which has a perforate section 5, and an outlet tube 4. Waste from the hopper 3 is driven through the pipe 2 by means of a screw auger 15 and anaerobic digestion of the waste occurs though contact with the liquor 8 in which the pipe 2 is immersed. A back pressure caused by a spring loaded flap 13 or other means causes a net loss of fluid from the waste to the liquor 8 as the waste passes through the pipe 2 and exits via the outlet tube 4. Thus waste of relatively high solids content, eg straw bedding, can be treated. The fixed path for the movement of waste reduces the risk of material passing through the digester with little or no treatment.   <IMAGE>

Title: Threshold control for a disk driving apparatus
Inventor: YUN JONG-YUN
IPC: G11B20/18
Filed: 1993-09-28
Abstract: A pulse width modulation, PWM signal having a duty cycle corresponding to a predetermined data threshold is generated by 200 and smoothed by C11. A read test is performed while the threshold is incremented by given stages to assign to a maximum value the threshold which is less by one stage than that generating a data error. The read test is then implemented while the threshold is decremented by given stages to assign to a minimum value the threshold greater by one stage than that generating a data error. The working threshold is obtained by averaging the maximum and minimum thresholds. The threshold adapted for each disk driving apparatus can be adjusted without modifying the hardware, and data errors can be prevented by adaptively adjusting the threshold to operating circumstances. <IMAGE>

Inventor: RODRIGUEZ-CAVAZOS ENRIQUE
IPC: H04N3/185
Filed: 1994-02-25
Abstract: A horizontal deflection circuit output stage (Q1, CR, LY, W1) generates a retrace pulse (V2) in a tertiary winding (W2) of a flyback transformer (T1).

Title: RF-based high-bandwidth signal transmission
Inventor: MORTENSEN KEITH Y
IPC: H04H20/77
Filed: 1994-09-09
Abstract: Each of a series of computer-generated input signals 10 (e.g., RGB baseband video signals) is frequency-modulated onto an intermediate frequency at 12, 14, 16. The intermediate frequency signals thus produced are then fed through RF mixers 18, 20, 22 and frequency-shifted to an assigned RF transmission channel. Each channel is then RF multiplexed 24 into a composite RF signal for providing a complete set of input signals to one or more monitors 42. Each monitor is provided with a splitter 28 to divide the composite multiplexed signal into its RF components, which are fed to RF mixers 30, 32, 34 to be shifted back to intermediate frequency signals. Demodulators 36, 38, 40 convert these intermediate frequency signals to output baseband signals corresponding to the input baseband signals. <IMAGE>

Title: Window supports
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/30
Filed: 1994-11-05
Abstract: In apparatus for supporting a component for movement between an open and a closed position, preferably a window friction stay, comprising a link arrangement including a first member 16 eg for mounting window frame, stop means are provided to allow a window sash, and a second member eg for securing to a movement of the first member relative to the second member from the closed to the open position in one direction but to prevent such movement in the opposite direction. As shown, the link arrangement includes further members 18, 22 and 26, the member 22 being pivotally mounted on the member 16 and extending between one end of the latter and a slider 24 in the track 10. On the same side of the member 16 as the member 22 there is mounted a plastics plate 20 providing a downwardly extending lug (21, Fig 2) which, when the stay is moved to a closed position, lies alongside an outer edge of the member 22. The lug (21) allows movement ofthe member 16, and thus opening of the stay, in the correct direction, but engages against the member 22 to prevent movement in the other direction and thereby prevent incorrect opening. <IMAGE>

Title: Lathe spindle
Inventor: HENNING RICHARD WILLIAM
IPC: B23Q1/70
Filed: 1995-09-21
Abstract: A lathe spindle (14) arranged to project from opposite sides of a lathe motor leg having, at both ends, a right-handed screw thread for engagement by a workpiece support means such as a face plate (12). By arranging for spindle rotation direction to be dependent on the end of the spindle being used to support a workpiece, only a single set of right-hand threaded workpiece support means needs to be provided. In a lathe incorporating such a spindle (14) the direction of spindle rotation is determined by the state of two micro-switches (90, 91) which are engageable by a cover positionable to prevent engagement with either an inboard end (16) or an outboard end of the spindle (14).

Title: A flexible protective cover with resilient hinged coupling elements
Inventor: SCHADECK FRITZ
IPC: B61D17/20
Filed: 1995-12-08
Abstract: A flexible protective cover for machine tools comprises rigid segments 1, eg aluminium extrusions, interconnected by resilient coupling elements 2, for example, of polyurethane. The segments 1 and/or the elements 2 are constructed in such a way so that they fold in on alternative sides. Alternate folding is achieved by providing the segments 1 with a curved surface 1d which encourages the direction of folding. The elements 2 has a greater amount of material on one side 2b than it does on the other side 2c. This results in unhindered folding on the side 2c and serves as means to further intensify the direction of folding. Sides 2b also serve as soundproofing since they prevent the longitudinal end faces 1a from striking each other. The segments 1 are retained by guide bodies (7', fig 5) in an upper guide rail (5', fig 5) and by guide bodies (8', fig 5) in a lower guide rail (6', fig 5) so as to be slidably and pivotably movable. <IMAGE>
