Title: Improvements relating to flexible sheet material
Inventor: PEARSON ROLAND WILLIAM
IPC: D06N3/00
Filed: 1964-05-29
Abstract: A leather-like sheet material comprises a layer derived by slicing a consolidated needle-punched mat of interpenetrated crimped continuous filaments bound by a resinous or elastomeric bonding agent.  The interpenetration of the filaments is in the nature of an intermingling at random in three dimensions, and is produced by laying the crimped filaments under tension and subsequently releasing the tension.  The filaments may be of nylon, polyethylene terephthalate, polyacrylonitrile polyolefine, rayon or silk.  The bonding agent may be a polyurethane rubber or precursors thereof, natural rubber, rubbery styrene-butadiene copolymer, butadiene/acrylonitrile copolymer, polychloroprene rubber or polyethylene, and may be applied in solution to the sheet after it has been formed and needled, but before it is sliced.  A layer of staple fibre may be applied to each side of the sheet and secured by the needling before the sheet is sliced, or a layer of interpenetrated crimped filaments may be attached to each side of a layer of staple fibres and the slicing effected through the staple-fibre layer.  Staple fibres, if used, may be of polypropylene and formed into a layer by carding.

Title: Improvements in and relating to electrical measuring, indicating or recording apparatus
IPC: G01R19/00
Filed: 1956-07-23
Abstract: 878,670. Electric tests. CAMBRIDGE INSTRUMENT CO. Ltd., and BECK, H. V. Oct. 23, 1957 [July 23, 1956], No. 22714/56. Class 37. In electrical measuring apparatus, a movable element is displaced to an extent dependent upon the value of an input current; a control current and a rate current, dependent respectively upon the extent and the rate of displacement of the element, being derived which cause a corresponding force to oppose the motion of the element; whereby the element rapidly assumes in dead beat manner a position indicative of the input current value; there being substantially no mechanical restoring force applied to the element. An input current is fed by way of amplifiers 11, 12 to a moving-coil galvanometer 13 having negligible mechanical restoring force, the moving coil carrying a vane 14 which forms, with vanes 15 and 16, a differential capacitor connected in a bridge circuit incorporating the primary winding 17a of a high-frequency transformer 17; high-frequency oscillations being applied across the bridge from a generator 18. The secondary winding 17b of the transformer 17 feeds a phase-sensitive rectifier 21, to which the output of generator 18 is applied as a reference; the output from rectifier 21 is fed to amplifier 12 and constitutes the control current acting in opposition to the input current. The rate current is derived by feeding the output of rectifier 21 to a differentiating circuit 22, the output of which is applied, through amplifier 24, to amplifier 12 where it is combined with the input and control currents. In modifications, the differential capacitor 14, 15, 16 may be adjusted by varying the separation instead of the overlap of the plates; the differential capacitor may be replaced by a device which modifies light incident upon one or more photo-electric cells, or by a movable coil adjacent two stationary coils.

[Also in Divisions F1 and G1] In apparatus for plotting the response of hydraulic or other servo mechanism 8, an adjustable speed motor 2 drives input member 6 through reciprocator 4, the output member 9 being coupled to transducer 10 acting as a modulator for oscillator 12. The modulated output of the transducer is applied to exciter windings 14 of a synchro resolver whose rotor is coupled to the motor 2 and which has secondary windings 18, 20 at 90 degrees to each other. One of the signals derived from the resolver corresponds to the product of the output of the transducer 10 multiplied by a sinusoidal signal in phase with the signal applied to member 6. The other signal corresponds to the product of the output of the transducer multiplied by a sinusoidal signal 90 degrees out-of-phase with the applied signal. The signals from windings 18, 20 are applied to demodulators 21, 22 respectively which also receive signals from the oscillator. The output signals from the demodulators are fed through low-pass filters 24, 25 respectively to the respective inputs of an XY plotter 26. As the test signal is varied in frequency by varying the speed of the motor 2, the plotter draws a polar diagram of which the amplitude corresponds to the movement of the member 9, and the angle represents the amount of lag of member 9 with respect to member 6. The servo mechanism may have an electrical input, and the synchro resolver may be replaced by a sine-cosine potentiometer.
