Title: Method and apparatus for controlling a spinning machine
Inventor: GORN IGOR VLADIMIROVICH
IPC: D01H1/32
Filed: 1986-10-15
Abstract: The method of controlling a spinning machine resides in stabilizing the number of unthreaded or idle spindles by controlling the yarn delivery rate and stabilizing the mean yarn twist value by controlling the rotational speed of the machine (ie of the spindles).   The apparatus for performing this method comprises a transmitter (1) of the number of unthreaded spindles, and a master generator (3), connected to the inputs of an add- subtract store (2) whose output is connected to a unit (4) controlling the drawing mechanism (6). The apparatus further comprises a transmitter (10) of the delivery rate of the drawing mechanism (6), and a transmitter (12) of the rotational speed of the spindles connected with a yarn twist value computation unit (11) whose output is connected to one line of an add-subtract counter (13) of which the other line is connected with a transmitter (14) of the specified yarn twist value, the output of the add-subtract counter (13) being connected with a unit (15) controlling the drive (17) of the machine. <IMAGE>

Title: Real-time control sequencer with state matrix logic
Inventor: ANDREW MARTIN BONAFFINI
IPC: G06F9/44
Filed: 1989-05-09
Abstract: A high performance, real-time control sequencer is disclosed which incorporates a unique state matrix logic. This real-time control sequencer performs rapid resolution of control processed state transitions and the required control actions as a function of detected external events and the current control process state. The control sequencer's micro-instructions present event and current state data as inputs to a state matrix logic and initiate state matrix operations. The state matrix, in turn, outputs data defining and initiating the next control process state, required process control 'actions to be performed by the control sequencer microcode, process status, and event response or control output data. The real-time, event-driven data processor invention provides greater flexibility for reconfiguring event patterns to be detected and responses desired. It provides for a faster resolution of control process state transitions and the required control actions, and it accomplishes this with a larger repertoire of event patterns and responses stored in a smaller memory area, than has been required in the prior art. The logic is part of a bus interface adapter in a real time fibre optic system.

Title: Mineral insulated cable manufacture
Inventor: SIMESTER RONALD ALEXANDER
IPC: H01B13/004
Filed: 1990-02-23
Abstract: Mineral insulating powder is injected by gas pressure into an advancing metal tube T from which the cable sheath is formed. The powder is delivered by tube 1 which extends into the metal tube and through which the conductor rods C are fed so that the powder fills the space around the rods within the metal tube and is partially compacted under gaseous pressure. Gas is expelled from the powder delivery tube 1 through filtered outlet ports 27 disposed in the wall of a fitting 26 secured to the downstream end of the delivery tube and effecting a filtered seal 28 with the advancing tube T downstream of the ports. Preferably, the advancing metal tube T is disposed horizontally and is continuously formed by bending an advancing ductile strip into tubular form and welding the edges of the advancing strip together. <IMAGE>

Title: A method of monitoring the sharpness of chaff-cutting blades
Inventor: FRIESE GERD
IPC: G01N27/60
Filed: 1990-08-10
Abstract: A method of monitoring the sharpness of chaff-cutting blades in chaff-cutting equipment comprises the step of detecting, while the equipment is rotating, voltage pulses induced in a transmitter by the cutting edge and the rear edge of a chaff-cutting blade brushing past. The peak voltages of those pulses are compared with each other by computation and a signal is issued when a predetermined limit value is reached. Since only the cutting edge becomes worn, the ratio of the peak values of the two pulses provides an indication of wear. The values may be processed digitally and a limit value of the ratio detected. The pulses may be produced by a magnetic sensor which may move to monitor the entire cutting face of the blade.

Title: Moulding sinterable material.
Inventor: HOLME JOHN DAVID
IPC: C04B35/634
Filed: 1991-08-23
Abstract: The invention relates to a method of hot injection-moulding a dispersion of sinterable powder (for example, of metal or high-melting-point non-metal such as silicon, or a ceramic substance such as silicon carbide, silicon nitride or alumina), using a dispersion of the sinterable material in a binder which, like the dispersion, is solid at room temperature and fluid at the temperature of moulding, with formation of a moulded product of uniform density. The binder employed comprises (i) polystyrene, which forms the predominant weight proportion of the binder, and (ii) in lower weight proportion, an organic compound (e.g. diphenyl carbonate) which is solid at room temperature, is soluble in the molten polystyrene, and is more soluble than the polystyrene is in a lower aliphatic alcohol or ketone. After formation of the moulded product, the binder is removed in non-solid form (e.g. as vapour, or by dissolution in a solvent, or by oxidation to volatile materials) to leave a porous structure of uniform density.

IPC: G10D3/18
Filed: 1992-02-08
Abstract: Certain stringed musical instruments such as the violin and viola, are held under the chin of the player so as to leave both hands free. This clamping with the neck can cause major problems in muscular tension and distortion of the neck and shoulder and may not hold the instrument very securely. A step 6 is provided on the chinrest 5 which engages inside and behind the jawbone 8 of the player giving a positive location and minimising the pressures needed to hold the instrument in position - particularly in conjunction with existing designs of shoulder rests. The step 6 may be integrally moulded or machined with the chinrest but having a detachable face piece (see also figure 6), or it may be separately fixed and detachable (Figure 5). <IMAGE>
