Title: Improvements in the production of iron powder having high electrical resistivity
Inventor: CLARKE SYDNEY GEORGE
IPC: H01F1/16
Filed: 1961-08-31
Abstract: Iron powder such as 1-10 micron size carbonyl powder is treated with a dilute aqueous solution containing 1/2-21/2 % by weight of phosphoric acid and 1/2-21/2 % by weight of chromic acid in relation to the weight of iron powder, the solution being agitated to keep the iron in suspension.  The treated iron has an electrically resistant surface coating which produces a specific resistivity of at least 10 megohm/cm cube when the iron is formed into a compact mass.  The iron powder may be treated in phosphoric acid before the chromic acid is added to the solution.  The powder is used as a magnetic core in H.F. electrical components such as R.F. chokes and transformers.

Abstract: 681,878. Automatic steering control systems. BENDIX AVIATION CORPORATION. Dec. 28, 1950 [Jan. 25, 1950], No. 31514/50. Class 38 (iv). In a system in which an A.C. servomotor positioning a member is controlled in accordance with a signal applied to a thermionic valve included in an amplifier and phase discriminator network which controls the servomotor through a balanced circuit, the balanced circuit is normally connected to an A.C. source but is automatically disconnected therefrom to discontinue operation of the servomotor upon loss of a voltage supply for the thermionic valve. As applied to an aircraft automatic pilot, rudder 10 is controlled by a two-phase servomotor 20, the energization of one phase 19 of which is controlled by signals from a stabilized earth inductor compass, a rate-of-turn device 13, and an inductive follow-up device 15, applied through lead 16 to one channel of an amplifier 17. Amplifier 17, which is of the type described in Specification 662,831, includes thermionic valves 54, 61, 62, which derive their H.T. supply from a rectifier valve 77, and magnetic amplifiers 72, 73 which derive their A.C. supply from a source 71. To prevent false operation of motor 20 in the event of failure of the H.T. supply from rectifier 74, a relay 88, which is normally energized from rectifier 74, is de-energized and opens contacts 90, 9] to de-energize phase winding 19 of motor 20. At the same time closure of contacts 92, 93 of relay 88 switches on a warning lamp 95. The ailerons and elevators of the aircraft are controlled from a gyro vertical 27 through addition channels of amplifier 17 in a manner similar to that in which the rudder is controlled. Turn of the craft is produced by a manual controller 14 which injects signals into all amplifier channels.

Filed: 1953-11-16
Abstract: 770,895. Programme distribution systems. PYE, Ltd. Nov. 11, 1954 [Nov. 16, 1953], No. 31695/53. Class 40 (4). In a programme (e.g. television) distribution system, the power for the receivers may be disconnected by a switch which is operated by a control signal of limited duration. As shown, at each receiver a relay 7 is provided whose armature is held in either position by residual magnetism and which may be changed manually from one position to the other by means of push-buttons " Off " and " On ", the relay controlling the supply of power to the receiver. To switch off the receivers a short D.C. signal is transmitted over the line and if a relay 7 is in its " on " position its coil 6 is energized and overcomes the attraction of the pole 7c to switch the power off. The relay may be replaced by a switch of the trip-overload type which may be operated by the D.C. signal. The D.C. signals may be repeated at intervals throughout a period of no programme. Instead of push buttons a coin-actuated mechanism may be used in which case a subscriber may be made to pay for each period between control signals.

[Also in Division G3] A free turbine engine in which a power turbine 16 is driven by the products of combustion from a gasifier has means to connect a power shaft 24 to the power turbine shaft 18 and further independant means to connect a governor drive 46, 52, 53 to the shaft 18, the last mentioned means comprising a hollow shaft 42 concentric to and splined to the power turbine shaft and gear means 38, 44 carried by the hollow shaft and the governor drive, the shaft 18 being supported in axially spaced bearings 20, 22 and the shaft 42 in an intermediate bearing 40. If the bearing 20 fails, a labyrinth seal 28 provides temporary support for the shaft 18 while failure of the bearing 22 causes the turbine to pivot about the bearing 20 so that the turbine blades will scrape their shroud before damaging the governor drive. If the shaft 18 breaks, the shaft 42 keeps the governor drive intact. The shaft 24 is connected through reduction gearing (not shown) to the rotors of a helicopter. The gasifier includes a compressor directing air into a toroidal shaped annular combustion chamber having a pair of axially-mounted turbines at its outlet.

Abstract: 211,572. Gray, W. T., North, N. E., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 22, 1922. Electromagnetic switches: pneumatic actuation.-Reversing switches for the field current of traction motors are constructed to occupy a minimum of space their width being small so that they may be mounted with the contactor switches. Two of these switches mounted side by side are shown in Figs. 1 and 2 each operated by a pair of pistons in a single casting 1 to which are attached electromagnets 23 controlling the compressed air valves. The piston rods are pivotally secured at 20, 21 to an intermediate rocking member 18 provided with metal attachments forming a pivot bearing 19 and slotted contact-operating members. The contacts 12, 13 are secured to insulating bobbins loosely mounted on' a shaft 11.
