Patent GB-356260-A (GB)
Title: Improvements in or relating to the production of fibrous thermoplastic sheets
IPC: C08J5/24
Filed: 1924-06-05
Abstract: Fibrous thermoplastic sheets are obtained by commingling in the presence of water a fibrous material and a plasticized resinoid composition, which is insoluble or practically insoluble in water, and laying the fibre-resinoid mixture into sheets which are then dried.  The plasticized resinoid composition is obtained by heating a reactive resin, preferably of the phenol-aldehyde type but comprising also resins of the urea-formaldehyde or glycerol-phthalic anhydride type, with a plasticizer which in the resinoid composition is practically insoluble in water and has a negligible vapour pressure at the ordinary temperature range, for example solvents including the dialkyl esters of organic acids such as the diethyl or dibutyl oxalates, tartrates, phthalates, &c., or substances such as naphthalene, naphthalene chlorides, or non-reactive natural or synthetic resins.  The heating is sufficient to render the resin wholly or partly insoluble in resin solvents.  The material is next comminuted by wet or dry milling, or in a colloid mill.  The admixture with the fibre in the presence of water is then effected in a beating machine as used in paper making, and the mixture is laid into sheets which are dried on rolls.  Laminated panels or other laminated products may be produced by superimposing a number of the sheets and consolidating them in steam-heated presses.

Abstract: 1,114,224. Measuring shaft power electrically; measuring shaft speed photo-electrically. WESTLAND AIRCRAFT Ltd. April 6, 1967 [April 22, 1966], No. 17672/66. Headings G1A and G1N. The power transmitted by a rotating shaft 1, Fig. 1, is determined by producing a series of pulses whose repetition frequency is indicative of the speed of rotation of the shaft and modifying the amplitude of the pulses in accordance with the torque in the shaft. This signal is then fed to a meter to give a direct indication of shaft power. The pulses are produced in a unit 3 which comprises a photo-transistor 7, Fig. 5, which conducts when light from a tungsten filament lamp 9 is reflected from one or more paint spots 12 on the shaft, on to it. The lamp and transistor are arranged in two compartments (6), (8), Figs. 2, 3 (not shown), of a moulded housing (5) on the shaft casing, the compartments being provided with apertures (10), (11) through which the light is transmitted and received. The pulses are shaped and polarized in the circuit of Fig. 5 and are supplied via an amplifier as the energizing voltage of a Wheatstone bridge of which two or four arms comprise torque detecting strain gauges 2 arranged on the shaft substantially as described in Specification 862, 462. The output from the bridge is thus a series of amplitude modified pulses as above. In a modification the speed of rotation of the shaft may be detected using a magnetic or mechanical pick-off.

Title: Improvements in or relating to Devices for Controlling a Machine Component over a Range of Speeds of a Moving System.
IPC: A24C5/31
Filed: 1967-04-19
Abstract: 1,185,519. Controlling a machine component. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 19 April, 1967 [21 April, 1966], No. 17914/67. Heading G4H. A device for controlling a machine component during a variation in the speed of the machine includes a shaft 3 (Fig. 1) rotating in accordance with the speed of the machine and a motion detector 1 delivering pulses to a threshold detector, the frequency and width of the pulses depending on the speed of the shaft so that when the machine is operating at a predetermined speed the component is operated. In one embodiment when the speed of the shaft drops to a predetermined value the voltage across a capacitor 6 drops to - u z  and a Zener diode 8 in the threshold device becomes conductive to render transistor 9 conducting and energize a relay 11, a further relay 13 holding the relay energized. One of the relay contacts controls an electromagnet of a machine component until the voltage across a capacitor 12 becomes insufficient to hold the relay 13 energized. By controlling the resistance of a potentiometer 7 the speed at which the relay is energized may be controlled. The relays may be replaced by transistorized logic circuits. In a further embodiment the relays are energized by a logic circuit controlled by two threshold detectors (16, 17, Fig. 4, not shown), tripped at speeds of V 1  and V 2  respectively to hold the relays energized during the time when the machine is decelerating from the speed V 1  to the speed V 2 . In a third embodiment the machine component is controlled whilst the machine is accelerating from start up to a speed of V 2 , using one threshold detector and pulses from the motion detector 1 to control logic circuitry. If it is required to control the component when a speed of V 1  is attained the logic circuitry is modified to energize the relay at this speed. In a further modification control of the component whilst the machine is accelerating from a speed V 1  to a speed V 2  is described.
