Abstract: 1284432 Collagenitic fibrous fabrics CENTRE TECHNIQUE DU CUIR SA 23 Oct 1969 [27 Nov 1968] 51964/69 Heading D1R Films of collagen prepared from acid dispersions of collagenic fibres in water or an organic solvent by extrusion from a flat die onto a moving support are transformed into fibrous cloths by cutting the film 2 into ribbons 6, chopping the ribbons into strands as by a rotary knife 33 and projecting the wet or dry strands on to an endless mat 35. If desired the ribbons may be processed into threads 6a and combined with different natural or synthetic threads or ribbons before being cut into strands of length 0.5-10 cm. A binding agent may be sprayed through nozzle 44. If synthetic leathers &c are required as the endproducts the binder is an emulsion or non- aqueous solution of polyvinyl chloride or acrylic polymer, polyvinyl acetate, butadiene copolymerised with styrene and/or acrylonitrile or polyurethane. If surgical dressings are the intended use then water is the binding agent and a polyol plasticiser. Powdered binders may be sprayed onto the inside of caisson 34 from nozzle 44. The strands and binder particles agglomerate on the moving mat 35 aided by suction and after consolidation between rollers 46 are passed to an oven 47 where the fibrous cloth is dried and the binder solidified. The ribbons 6 may be subjected to other treatments such as tanning, dyeing plasticising and/ or waterproofing either before or after they are cut up into strands.

Abstract: 1437785 Brushless motors; control of brushless motors FERRANTI Ltd 26 Nov 1973 [30 Nov 1972] 55388/72 Headings H2A and H2J The rotor position of a self-starting brushless D.C. motor 10 is sensed by a capacitive device comprising one metal electrode 17 connected via shaft 12 and motor casing 11 to a pulse generator 21 (Fig. 3) and mounted on the rotor shaft 12, and a plurality of stationary metal electrodes 14 mounted on a printed circuit board 13 (slidable relative to shaft 12) and connected through combined demodulators and amplifiers 22 to respective field windings of the motor. The stationary electrodes are angularly adjustable to permit reversal of the motor. Where the stator has an odd number of windings there are two electrodes 14 for each winding. The demodulator/amplifiers are connected to the field windings through output amplifiers 24 controlled, as described later, by speed stabilizing components. The electronic control circuitry is formed as an integrated circuit 28 mounted on the printed circuit board 13. Motor control functions. Reversal is effected by rotating the board 13 through 180 degrees relative to the motor field windings, when the latter are of even number equal to the number of electrodes 14. When the number of windings is odd, there are twice as many electrodes 14 arranged in two sets, each connectible to the windings to produce rotation in one or other direction. Speed regulation is effected by control of the amplifiers 24 by a comparator 31 fed with a desired speed signal from member 30 and an actual speed signal from a frequency-to-voltage converter 32. Each amplifier 24 may comprise a switching transistor in series with a load resistor and controlling a motor winding, the base of the transistor being controlled by a second transistor. The actual speed signal may be the sensed winding back EMF instead of the current pulse frequency. Amplifiers 24 may be controlled to vary the duration of the current pulses to the windings or to restrict the winding current to a maximum value. Operating characteristics.-The relationship between the outputs of member 21 and the pairs of members 22, 24 is discussed, Figs. 4a, 4b and 4c (not shown), the drive angle (current duration) and current amplitude being simultaneously adjustable by adjustment of the demodulator/amplifiers 22 to provide a desired motor characteristic, e.g. optimum efficiency, selected maximum current or high starting torque (large overlapping of the winding currents) with minimum drive angle for subsequent running.

In one embodiment, a steel workpiece 16 is mounted on a platen 18 which is mounted on shafts 24 which can be eccentrically mounted relative to shafts 31. The shafts 24 are attached to heads 28 which are adjustable relative to the shafts 31 to enable the degree of eccentricity to be adjustable. The workpiece 16 is electro-eroded to form the cavity 14 by an electrode replica 12, which is intermittently withdrawn to enable the workpiece 16 to be eccentrically rotated through arcs of 1-180 degrees by rotating the shafts 31 by a motor 56. The workpiece 16 is rotated through at least one revolution. The electrode 12 may alternatively be eccentrically rotated. In another embodiment, the master die 16 is made by lowering the electrode 12 into sand in a container, which is mounted on the revolving platen 18. A plaster cast is made of the oversize cavity 14 produced and plastics containing silicon carbide, tungsten carbide or aluminium oxide abrasive particles is poured over the cast. After curing the plastics, the plaster is removed to leave a master die 16. Alternatively, the electrode 12 is lowered directly into a plastics mass which is cured before removal of the electrode 12. The master die 16 produced and an electrode workpiece are mounted in alignment and moved towards each other whilst one is rotated with the same eccentricity as that used to make the master die 16 so as to produce an electrode which is undersize relative to the cavity 14 and the same size as the electrode replica 12.
