Title: Improvements in and relating to receiving aerial systems
Inventor: MONTEATH GEORGE DEWAR
IPC: H01Q1/50
Filed: 1958-12-10
Abstract: 868,424. Aerials. BRITISH BROADCASTING CORPORATION. Nov. 10, 1959 [Dec. 10, 1958], No. 39909/58. Class 40(7). An aerial system arranged so that the effect of precipitation static is reduced comprises an aerial element or group of elements having terminals for connection to a receiver and a discharge conductor having its extremity located at least as far from the centre of the element or group as any point on the element or elements and so disposed that currents in it have small or negligable effect at the terminals. In one embodiment the aerial element consists of a folded dipole 10 mounted centrally on a metal mast 11. The mast is continued upwards from the centre of the dipole as a pointed discharge conductor 12 whose tip is at least as far from the centre 14 as the aerial element extremities. The output from the folded dipole is derived in balanced form to maintain symmetry with respect to the conductor 12 but a balance to unbalance transformer 16 and coaxial feeder may be used if required. The folded dipole may be replaced by a straight dipole or a vertically stacked array of dipoles. Where a broadside array of horizontal dipoles is to be used it is possible to use separate discharge conductors for each element; it is more convenient, however, to use a single centrally arranged conductor and to support the array from a single central mast (Fig. 2, not shown). In a further embodiment the discharge conductor extends upwards symmetrically between two vertical folded dipoles forming a directional array (Fig. 3, not shown). The path to earth from the point of the discharge conductor may include resistive or inductive portions to restrict the current flow. Various forms of resistive and inductive discharge current paths are described with reference to Figs. 4 to 7 (all not shown). These arrangements may be used where, owing to lack of aerial symmetry, the discharge current produces a small output at the aerial terminals.

Alloy powder granules for use in powder metallurgy are made by heating in a reducing atmosphere at a temperature below the melting point but high enough to cause pre-alloying, an unalloyed mixture of Fe powder, a Mo compound, Cu or a Cu compound, and Ni or a Ni compound, discontinuing the heating before complete alloying occurs and grinding the agglomerated particles. The mixture is preferably heated in dissociated ammonia or hydrogen at 1300‹ -1850‹ F. and the ground particles are preferably annealed at about 1350‹ F. The mixture may also contain polyvinyl alcohol, gums or starch as a binder and about 0À5% of graphite or stearic acid. The following compounds may be used; nickel glyaxine, nickel nitrate, nickel formate, ammonium molybdate, molybdenum nitrate, molybdenum trioxide, molybdic acid, copper oxide, copper formate and copper nitrate. The mixture may be formed from the dry powders or by mixing Fe powder with an aqueous solution of the salts of the other metals. The alloy powders produced contain 1À5-3% Ni, 0À4-1% Mo, 0À5-2% Cu, balance Fe. The granules have a very low shrinkage on compacting and sintering.

Abstract: 963,647. Control of D.C. motors; battery charging arrangements. SEVCON ENGINEERING Ltd. Nov. 1, 1962 [Nov. 25, 1961], No. 42225/61. Headings H2H and H2J. A self-propelled vehicle comprises traction motor A which is adapted to operate as a generator for charging a storage battery, the charging current being controlled by a pulse generator circuit P, and means are provided for adjusting the pulse frequency and thereby the mean power supplied to the battery. When the vehicle is running in the forward direction and the brake is applied, switch S1 is closed to energize motor field winding W2, and a signal is transmitted to render gated diodes 2 conductive and diodes 1, 1a, non-conductive. Charging current then flows through diodes 2, the circuit P, and diodes 2a. The rate of battery charging increases with depression of a brake pedal and consequential movement of the slider of a potentiometer which controls the pulse rate. A similar process of regeneration takes place when the vehicle is reversed, but in this case the gated diodes 1a are conductive whilst the diodes 1, 2 are non-conductive. The pulse generation circuit also serves for controlling the motor when it drives the vehicle, Specifications 950,734 and 963,648 are referred to.

Title: New or improved control means for hydraulic actuated apparatus

Abstract: 935,364. Fluid-pressure servomotor control systems. INDUSTRIEWERKE KARLMARX-STADT VEB. Dec. 12, 1959, No. 42336/59. Class 135. A control means for the piston 10 of an hydraulic actuator comprises a cylinder 1 in which is slidably-mounted a control piston 2 connected to a piston 3, by a loaded coupling spring 9 so that the force exerted by the spring in conjunction with the applied pressure of the hydraulic medium determines the displacement of the piston valve. In operation, with the control means in the position shown, pressurized fluid is fed via a valve through a port 17 into a chamber 16 thereby acting on the control piston 2 to move it against the action of the spring 9 so that ports 23, 24 are uncovered, the piston 3 remaining stationary due to its connection with a cam-slot 11 in the actuator piston 10. Pressurized oil is then able to flow through a port 18 into a chamber 5 and thence via the port 23 to act on one side of the piston 10, exhaust oil on the other side flowing to a reservoir via port 24, chamber 6 and ports 19, 20; upon movement of the piston 10 the piston 3 is moved together with the control piston until ports 23, 24 are again closed and the movement of the piston 10 ceases. Further successive admissions of control fluid into the chamber 16 causes the piston 10 to be moved until.it reaches the end of its stroke; by successively reducing the pressure in the chamber 16, the piston 10 may be returned to its normal central position. To move the piston 10 in the opposite direction, the control fluid is fed into the chamber 12 thereby acting on the control piston so that the ports 23, 24 are uncovered, the pressurized oil then flowing via port 18, chamber 5, port 24 to act on the opposite side of the piston 10. Further operation is as described above. A reduction gearing, such as a differential lever, may be connected between the cam 11 and piston 3.
