Patent GB-2067426-A (GB)
Title: Tumbling centrifuge
IPC: B04B3/00
Filed: 1980-12-18
Abstract: A tumbling centrifuge is provided with a centrifugal drum which has a perforated jacket and which is widened towards the discharge end. Rotation of the centrifugal drum about two axes simultaneously causes a tumbling movement which effects discharge of the material. The two rotations are effected by a central shaft 3, rotating at speed n1, and a hollow shaft 7, rotating at speed n2, the shaft axes intersecting at a tumbling angle  tau . The empty drum has a moment of inertia about its axis of symmetry of  theta w and a moment of inertia about an axis perpendicular thereto of  theta u, and the ratio of the two moments of inertia, including all the parts which are inclined at the tumbling angle  tau and rotate at the speed n1, is  theta w/ theta u = 0.55 to 1.1, preferably 0.70 to 0.80, at a speed ratio n2/n1 of 0.7 to 1.25. <IMAGE>

Title: Improvements in sealing a leak in a pipe or pipeline carrying fluid under pressure
IPC: F16L55/175
Filed: 1981-02-12
Abstract: A leak in a pipe or pipeline carrying a fluid, such as natural gas, under pressure is sealed by securing a vent pipe 3 to a pipe at the point where fluid is leaking and a sleeve 13, formed in a first wrapping of a flexible sheet material forms a sheath for the pipe 3. The sleeve 13 is sealed to the pipe 3 by means of a clip 25 after and wrapping 1 is circumferentially wrapped around to form an inner enclosure into which leaked gas issues. A sleeve 14, formed in a second wrapping 2 of flexible sheet material, also sheaths the pipe 3 and is sealed thereto by a clip 26 after which the wrapping 2 is circumferentially wrapped around the main 34 to overlap the wrapping 1 and form an outer enclosure therewith, and a cold curing resin is introduced into the outer enclosure through a further sleeve or funnel 15 in the outer wrapping 2 and the resin is allowed to harden, after which extension pipe and flame trap are removed and the vent pipe 3 is sealed with a plug 21. <IMAGE>

Patent GB-2080584-A (GB)
Title: Binary-coded-decimal to binary converter
IPC: H03M7/12
Filed: 1981-06-29
Abstract: The converter employs a selection network 1 in which the applied binary coded decimal digits are selected in pairs of increasing order of decimal denominational significance to be passed to the address lines of a pair of memory elements 11, 21. The locations of the memory contain the binary terms equivalent to the decimal digits from which the particular location address is derived. The notional capacity of the locations in terms of the number of binary denominations specifiable may be increased by separately generating bits of higher denominational significance, and this separate generation may take the form of a logic gating operation 31 applied either to generate a binary term directly or to re-allocate the denominational significances of bit positions within a location. <IMAGE>

Title: A monitor and method of monitoring
IPC: D04B35/14
Filed: 1982-02-09
Abstract: A yarn monitor for use in a gripper loom comprises infra-red sensors (8) mounted on respective knife blocks (6) and signal processing circuitry for processing the sensor outputs to make it acceptable for analysis by a computer. The presence of each yarn generates a pulse and the gap between each pair of adjacent pulses is compared by the computer with the average gap of the eight preceding pairs to indicate whether the gap is so large as to signify a missing yarn. The computer can be set to generate an alarm when a missing yarn is detected so that a fault in the carpet does not result. The monitor can be applied to other types of loom. <IMAGE>

Patent GB-2118007-A (GB)
Title: Adjustable coring circuit
Inventor: HARWOOD LEOPOLD ALBERT
IPC: H04N9/64
Filed: 1983-03-28
Abstract: Signals to be cored are applied to the inputs of a linear signal amplifier (13), and of a multistage limiting amplifier (15) having cascaded input and output amplifying stages. A cored version of the signals, corresponding to the difference between a linearly translated version of the signals and a doubly clipped version thereof, is developed by a signal combiner (17) responsive to the outputs of both amplifiers. A variable coring level control voltage (21) controls the distribution of gain between the input and output amplifying stages, substantially without disturbing the overall gain of the limiting amplifier, which is set to match the overall gain of the linear amplifier. In an illustrative embodiment, the signals which are adjustably cored are horizontal peaking signals derived from the received luminance signal in a color television receiver. An automatic peaking control system associated with output of the adjustable coring circuit opposes changes in peaking level that might otherwise accompany coring level adjustment. <IMAGE>

Title: Lift system
Inventor: HUSSON ALAN LOUIS
IPC: B66B1/36
Filed: 1983-07-11
Abstract: A lift system having an overspeed monitoring function for monitoring terminal stops includes an electromechanical transducer (52) arranged to provide a first signal (ECI) related to desired or nominal speed as a function of the distance of the car from the terminal floor. The first signal is processed (86) to have substantially the same magnitude and slope as a second signal (TACI) produced by a tachometer (70) during a normal terminal slowdown. The first and second signals are compared (82) to provide a deviation or error signal which in turn is compared with a reference (92) selected according to the maximum allowable speed error. Should this maximum allowable speed error be reached, the overspeed function provides a signal which may be used to initiate an emergency terminal stop. <IMAGE>
