Title: Improvements in or relating to the manufacture of decorative fibrous sheet material and plaster board
IPC: D21J1/16
Filed: 1935-02-14
Abstract: 453,648. Decorative compound sheet materials; plaster boards. TYCE, G. C., Norton Hall, The Green, Norton-on-Tees, and LEFEBURE, V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Feb. 14, 1935, No. 4828. [Classes 96 and 140] [See also Group X] Decorative fibrous sheet material is made by superimposing a sheet of resin-impregnated paper upon a layer of unimpregnated decorative or printed paper, cloth or similar fabric material, backing the lower layer with a sheet of unimpregnated absorbent paper and treating the whole under heat and pressure so that the resin is caused to flow through and cement the layers together, the heat and pressure treatment being so controlled that impregnation is complete throughout the upper layers but the resin only partially penetrates the under layer of absorbent paper. In a modification, the top layer of paper is not impregnated with resin but the resin is applied thereto, allowed to dry if necessary and the whole treated under heat and pressure. Pigments or the like may be incorporated in the top layer of paper or in the resin applied thereto. Suitable resins are urea formaldehyde, thiourea formaldehyde, phenol formaldehyde, methyl methacrylate, styrene or paralac resin. Plaster board or panels may be formed by covering a layer of plaster on both surfaces with pulp board or like lining, one or both of these linings having an external layer or layers of the decorative sheet material bonded thereto preferably by a water-proof adhesive.

Title: Precision tracking of electrically tuned circuits
IPC: H03J7/00
Filed: 1964-02-05
Abstract: 1,056,701. Automatic tuning control; receiver tuning. GENERAL DYNAMICS CORPORATION. Feb. 5, 1964 [Feb. 7, 1963], No. 4845/64. Headings H3A and H3Q. An arrangement for tuning a resonant circuit 1, including a voltage variable capacitor 3, comprises an oscillator 18 with a frequency-determining circuit 21 which includes voltage-variable capacitor 29 and a frequency discriminator 45 to which the oscillator output voltage is applied which supplies a D.C. output voltage to the voltage variable capacitors to tune the resonant circuit and the oscillator to the centre frequency of the discriminator. In a second arrangement, Fig. 2, the frequency discriminator is replaced by a phase discriminator to which the oscillator output and the output of a variable-frequency oscillator 40 are applied. The discriminator supplies a D.C. output voltage which is a function of the difference in frequency, which tunes circuit 1 to the frequency of oscillator 40 and locks the frequency of oscillator 18 thereto. In a receiving arrangement, Fig. 4 (not shown), including three tunable R.F. circuits 12, 13 and 14, the oscillator 18 becomes the receiver local oscillator which is controlled via the phase discriminator to the frequency of variable-frequency source 40. In this case the resonant frequency of the oscillator tank circuit 21 is displaced, e.g. by adjustment of tuning coil 25, by the amount of the I.F. from the resonant frequency of the R.F. circuits.

[Also in Group XXVI] Gas is intermittently supplied to the main burner 6 of a flashing beacon, under the control of a valve 5, from a chamber 10 by way of a diaphragm-operated pressure-regulating valve 21, a conduit 12 in which is a cock 13, and a chamber 1 that houses the valve 5; a pilot burner 18 is also supplied from conduit 12. The valve 5 is actuated by a cam 4 driven from a spiral spring 2 having an escapement 3, the spring being wound through a ratchet wheel 16, and a rod and pawl 15 connected to a pulsating diaphragm motor, the diaphragm 8 of which is loaded on its upper face by a spring 17 and the gas pressure in chamber 1, whilst the operating pressure applied beneath the diaphragm is obtained from the chamber 10 and its entry into and exhaust from the motor is determined by a double valve-closure 9 connected through a snap-action device 14 to the diaphragm. When the pressure under the diaphragm 8 has risen sufficiently the diaphragm is upwardly deflected and both moves the ratchet wheel 16 one tooth and causes the closure 9 to tilt thereby sealing a motor inlet 9a and opening the outlet 9b; the opposite action occurs when the diaphragm completes its return stroke. The motor outlet 9b is connected to conduit 12.

Abstract: 990,687. Engine indicators. TELECTROMEK Inc. Feb. 13, 1962 [Feb. 17, 1961], No. 5438/62. Heading G1L. [Also in Divisions G3 and G4] A method of measuring the gross and net thrust developed by a jet propulsion engine comprises sensing at least three independent pressures, of which at least one is inside and at least one outside the engine, producing signals representing the pressures and functions of combinations of the pressures and combining the signals, without introducing any other variable, to obtain the required measurement. Static and total pressures are detected by probes placed at stations 2, 6 of a jet engine, Fig. 1, as representative of the pressures in the compressor (12) and nozzle (25) entrance regions respectively. Probes 35, 36 outside the engine detect the "normal shock" total pressure and static atmospheric pressure. Pressure lines connect the probes to function generators 40, 41, 42, 43, 44 which produce the following ratios "compressor entrance flow pressure", "ram", "normal shock ram", "expansion" and "exit or nozzle entrance flow pressure". These ratios are used as required by the components of various systems 46 illustrated in block diagrams Figs. 11-19 (not shown) made up of electric or pneumatic components and based on the general thrust equations disclosed in outline but incorporating undisclosed predeterminate functions. The equations giving gross thrust include a function of the nozzle entrance flow pressure ratio and may include a function of the expansion ratio while those giving ram drag, i.e. the difference between gross and net thrust, include a function of the compressor entrance flow pressure ratio and may include a function of either the ram ratio or the normal shock ram ratio. Simplified equations are given of sufficient accuracy for aircraft flying at Mach numbers below 1. 3. Suitable electric components are illustrated in Figs. 5, 7, 9 and 20 (b) (not shown, but see Division G4) and suitable pneumatic components are illustrated in Figs. 4, 6, 8, 10 and 20(a) (not shown, but see Division G3.) The final component in any of these sytems may be suitable calibrated pressure gauge or electrical synchro-receiver in the pilot's cockpit and/or the final signal generated may be used for purposes of engine and/or aircraft performance control.
