Title: Improvements in or relating to tar and the like spraying machines
IPC: E01C19/17
Filed: 1949-02-14
Abstract: 701,780. Spraying tar. GRANT, GALLOWAY & GEAR, Ltd., and GALLOWAY, F. Jan. 6, 1950 [Feb. 14, 1949], No. 3964/49. Class 107. [Also in Group XXIX] A tar spraying machine has a hollow spray bar in which a continuous flow of tar can be maintained when the spray valves are shut by means of a return valve connected to open when the spray valves are closed. The spray bar 1 entirely contains the valve assembhes 4 thus preventing the tar in the valves and nozzles from solidifying when spraying is stopped. The spray bar has an inlet 2 for the liquid tar and an outlet 3 fitted with a valve 5 which is opened by a lever 6 to allow free circulation of the tar when the valves on the assemblies 4 are closed (also by the displacement of lever 6) through the agency of notched bar 7 and the individual valve links 9. When certain jets are required to be out of action the appropriate links are swung back, as shown, to disengage them from the notches in bar 7. The valve for each jet is preferably as disclosed in Specification 701,735, [Group XXIX], and through the agency of chordal valve springs, a whirling flow is set up above the nozzle 18.

Title: Improvements in and relating to directional wireless aerial systems
IPC: H01Q21/12
Filed: 1934-02-07
Abstract: 432,978. Aerials. BLUMLEIN, A. D., 7, Courtfield Gardens, Ealing, London, and PAWSEY, J. L., 3, Dale Avenue, Hounslow West, Middlesex. Feb. 7, 1934, No. 4093. [Class 40 (v)] A directive aerial comprising four elements arranged in two pairs, of which at least two adjacent elements are spaced apart by less than a quarter of the working wavelength, the overall spacing of the four being less than three-quarters of the working wavelength, is characterized by the feature that the currents fed to one element of each of the two pairs is substantially 180‹ out of phase with that fed to the other element, whilst the average current flowing in the two pairs is similarly de-phased. As shown in Fig. 1, the antennae A, B are connected in pushpull to the inner and outer conductors 3, 4 of a balanced feed-line 5, the other pair C, D being similarly connected to a branch line 6. The length of the branch line is such that the average phase of the currents in A B is # + 4#/n degrees out of phase with the currents in C, D, n being not less than four and preferably greater than eight. In Fig. 2, the overall spacing is the same as in Fig. 1 though the distance between adjacent aerials E ... H is varied. Coupling to the feedline 18 is effected through a transformer arrangement 22 comprising the upturned ends 11 of the aerials, bridged at 14 to a pair of parallel wires 12 joined at their ends through a resistance 12 (to prevent side-band cutting) and enclosing a loop circuit 15, 16 branched across the inner and outer wires of the feedline 18. The latter is coupled to the main feeder 19 through an impedance transformer comprising a condenser 20 and the exposed wires 21. Fig. 3 shows one pair of aerials K, L fed in push-pull from a feeder 23, and a second pair M, N fed from a branch feeder 23<1>, the two feeders 23, 23<1> being connected through branches 27, 271 and phase-adjusting condensers 30, 301 to the main feeder 35. Auxiliary end-branches 36 act as rejector circuits to attenuate undesired currents flowing in the outer sheaths of the feeders. The directional characteristic is of the form shown in Fig. 5. The pairs of aerials may be orientated in different planes, which may or may not be parallel to each other. The close spacing reduces the radiation resistance though it is stated to increase the aerial current for a given input of power. For domestic reception the aerial system may be carried by a single mast supported from the roof or from a chimney.

Title: Fluid flow machine
IPC: F02K1/78
Filed: 1970-01-28
Abstract: 1284341 Turbine, compressor and fan blade assemblies ROLLS ROYCE Ltd 28 Jan 1970 4136/70 Headings F1C, F1J and FIT A fluid-flow machine comprises an annular duct in which is mounted a ring of rotor blades there being at least one vane disposed downstream of the ring of rotor blades, the or each vane extending across the duct and being bent in a circumferential direction such that at least part of its leading edge lies in a plane which is substantially orthogonal to the plane containing the wake or wakes streaming in operation from one or more of the rotor blades whereby wake interaction between the blades and the or each vane is substantially reduced or eliminated. The invention is described with reference to a gas turbine ducted fan engine comprising fan rotor blades 15 and outlet guide vanes 17 located in a fan duct 16 defined between a fan casing 11 and the casing 12 of a gas turbine engine which drives the fan. The guide vanes 17 are bent outwardly in a circumferential direction opposite to the direction of rotation 20 of the fan blades 15. The radial limits of a "ribbon of wake" streaming from the trailing edge 22 of a fan rotor blade 15 are indicated at 30, Fig.3, and due to the circumferential bending of the guide vane 17 it can be seen that the plane of the "ribbon of wake" is substantially orthogonal to the plane in which the leading edge 24 of the guide vane lies. The object of the invention is to reduce noise level. Layers of sound absorbing material (35) may be disposed on the inner and outer walls of the fan duct, Fig.1 (not shown). The invention is applicable also to other machines such as a compressor duct or a turbine duct of a gas turbine engine.
Patent GB-892971-A (GB)
Title: Improvements in or relating to electric circuit arrangements employing bi-stable magnetic cores
Inventor: HAYWARD RODNEY KENNETH
IPC: H03K3/45
Filed: 1957-02-06
Abstract: 892,971. Circuits employing bi-stable magnetic cores. POSTMASTER GENERAL. May 6, 1958 [Feb. 6, 1957], No. 4150/57. Class 40 (9). [Also in Group XL (c)] Two amplifiers are each connected as one shot oscillators by having feed-back over saturable magnetic cores, the cores being cross-connected so that when one amplifier is triggered to conduct it resets the core of the other amplifier to a state in which it may in turn be triggered. As shown, transistors VT1, VT2, are connected for feed-back between windings B and C of their associated cores X1 and X2 and are cross-connected with windings D. A common winding E sets the cores so that an input pulse on windings A tends to shift flux in one core but not the other. In the core in which flux is shifted feed-back occurs once the transistor is made to conduct by voltages induced in the B and C windings and the transistor continues to conduct until the core reaches saturation and coupling between the B and C windings breaks down. Conduction through the D winding of the other core reverses its saturated state so that on reception of the next pulse on windings A the other transistor conducts. The input pulses need not be applied to the separate windings A but may. be applied directly to either of the windings B or C. The input pulses are derived from a random source applied to terminal T1. A pulse on terminal-T1 is passed by a conducting rectifier W1 to a pentode V1 which switches. on a normally non-conducting pentode V2 for a period of time depending on the discharge of capacitor C1 While V2 conducts, rectifier W1 is cut-off to refuse admission to further pulses appearing on terminal T1 so that the output from the anode of V2 to a transformer T comprises a pulse train with a fixed minimum space between pulses. So long as input pulses occur above a given frequency a capacitor C4 is not allowed to charge sufficiently to trigger cold-cathode tube V3. When the pulses fall below this frequency, V3 strikes and operates an alarm.

Title: Improvements in or relating to control systems for electric motor driven vehicles
IPC: B60L15/12
Filed: 1943-03-19
Abstract: 570,215. Master control of D.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 19; 1943, No. 4517. Convention date, March 19, 1942. [Class 38 (iii)] A vehicle is retarded by both electric and air pressure braking in such a manner that both are increased together by means of a relay C sensitive to air-pipe pressure. Acceleration is effected by closing master controller contacts MC71, thereby energising and closing contactors LS, L, MI, R and G. The motor accelerates by reduction of resistor A, of the type described in Specification 431,224, driven by a pilot motor 44 under the control of contacts 82, 83 on a relay LR having a motor current coil 47 and a " tickler " coil 53. Acceleration rate is increased by energizing one or both biassing coils 56, 57 on the relay LR over master control contacts 91, 92. During coasting contactors B.1, B2 and L are closed, and " spotting" of resistor A is effected by a spotting coil 49 on relay LR which controls forward and reverse movement of pilot motor 44. A coasting relay CR energised by back E.M.F. of motors maintains its contacts 126 closed during coasting, but when vehicle comes to rest it opens contacts 126 and closes 135 to return resistor A to maximum position ready for the next acceleration. Braking is instituted by energising a braking relay BR over contacts BC138 on a braking controller. This relay opens 123 to de-energise the "spotting" coil 49, and closes 144 to energise "rate" coil 52 on the relay LR which then causes pilot motor 44 to adjust resistor A to give required braking current. If air braking is increased, pneumatic actuated, relay C increases energisation of coil 52 opposing coil 47 and thereby causes electric braking to increase correspondingly.
