Abstract: 817,571. Nucleonics. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 10, 1945 [May 8, 1944], No. 11801/45. Class 39(4). Neutron absorption in a moderator is determined by measuring two different density distributions of thermal neutrons within a mass of the moderator. By using a Ra-Be source 29 of fast neutrons the thermal neutron densities in a rectangular block 24 of graphite are measured by means of indium or rhodium foil 19 inserted successively in slots 30. These measurements are made with firstly cadmium foil 25 surrounding the block on six sides and secondly with the cadmium sheet on the top of the block removed. The densities may be measured in a sphere of graphite with a central neutron source firstly with a cadmium sheet wrapped around the sphere and then with it removed, the sphere being in a tank of water or paraffin for all measurements. Similarly absorption in beryllium or heavy water can be measured. The diffusion length is calculated from the results obtained.

Abstract: 386,503. Alternating-current induction motors. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, ROBERTS L. and BALL, R. D., Phoenix Works, Bradford, Yorkshire. April 27, 1932, No. 12152. [Class 35.] Windings; motors, controlling.-In a splitphase motor having a sectionalized main winding and employing capacity in the starting winding, both windings remain in circuit during running, and switchgear is provided to reduce the capacity in series with the starting winding and to regroup the section of the running winding so as to decrease its impedance and to make all sections effective. In the form shown, the main winding is divided into two sections 1a, 1b, and the starting winding is in series with condensers 3, 4. With the switch handle 5 in the upper position for starting, switches 6 .. 9 are closed and the sections 1a, 1b are connected in series across the mains A, B. At the same time the condensers 3, 4 are connected in parallel and in series with the starting winding 2 across the mains. With the switch handle 5 in the lower position, for normal running, switches 6 .. 9 are open and switches 11 .. 14 are closed and the sections 1a, 1b are connected in parallel. The starting winding remains in circuit with the condensers 3, 4 in series with each other. In a modification, the switchgear is arranged to disconnect one of the main winding sections at starting and to connect the two sections in parallel for normal running. Three examples of main winding are described, namely, two forms of double layer winding for a 2 pole 16 slot motor and a concentric single layer winding for a 2 pole, 12 slot motor. Instead of changing the condenser grouping as described, one or more condensers may be short-circuited or cut into or out of the circuit. A single three-plate condenser may be employed.
Patent GB-581865-A (GB)
Title: Improvements relating to fluid pressure braking apparatus for railway and other vehicles
IPC: B60T15/08
Filed: 1944-06-27
Abstract: 581,865. Brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and SIMMONS, A. W. June 27, 1944, No. 12171. [Class 103 (i)] A fluid-pressure braking-apparatus of the kind in which the driver's handle controls the operation of selflapping electrical control devices, or, in the event of the failure of the electro - pneumatic control, controls the brakes by varying the train pipe pressure, is characterized by the pneumatic control positions of the handle being substantially coincident with the corresponding positions for electro-pneumatic control. In the driver's control device shown, the handle H is shown in the release and running position I. The electro-pneumatic full-service position is at IV; III being the pneumatic service position and II the pneumatic lap position. The range between III and IV is used for the electropneumatic control and V is the emergency application position. In order normally to prevent a pneumatic service application in position III an interlock valve device is provided which, when energized, keeps an exhaust port for the equalizing reservoir closed. When the interlock valve is de-energized, the exhaust port opens and pressure in the equalizing reservoir falls to cause a corresponding fall in the train pipe. The service rate of pneumatic brake application may be maintained up to a convenient position between III and IV at which position a change over to pneumatic emergency application occurs, e.g., by the rotary valve venting a passage leading to an emergency valve, such as a dead-man's application valve. Alternatively, instead of a sudden change from pneumatic service to emergency rate between III and IV, the application rate may be changed continuously or in steps between III and IV from the service rate to emergency rate. The normal emergency position V is, in all cases, provided. For electro-pneumatic control it is not desirable to have notches defining II and III, which notches are required for pneumatic control. A locating latch is, therefore, provided which is held out of operative position when the interlock valve device is energized, e.g., the latch may be controlled by a spring-loaded piston maintained in the "latch inoperative" position by fluid pressure. When the interlock valve is de-energized the pressure is vented and the spring positions the locating latch for pneumatic control. With pneumatic control, graduated release valves with triple valves, or triple valves of the graduated release type, may be used. According to the Provisional Specification, a driver's control device for non- self-lapping electro-pneumatic application and pneumatic application, with substantially coincident control positions of the handle, may be used.

Title: Improvements in and relating to electrical phase shift means
IPC: H02M1/02
Filed: 1932-12-17
Abstract: 413,741. Converting; phase changing. FITZGERALD, A. S., 433, Warwick Road, Wynnewood, Pennsylvania, U.S.A. Dec. 17, 1932, No. 12188/34. Divided on 413,671, under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 19, 1933. [Class 38 (ii).] A phase-shifting circuit comprises a network 11, supplied from A.C. input voltage, including reactive impedance 12, 13, 14 and a resistance element 15 having a non - linear currentresistance characteristic, element 15 being responsive to a controlling voltage or current, at 17, independent of the input voltage, for varying its resistance, the passage of energy from the network to the source of controlling voltage being prevented, e.g. by inductance 19 or rectifier 18, so that continuous variation of the resistance 15 produces continuous variation in the phase of the output A.C. from the network relatively to the input voltage. The network 11 may be in the form of a capacity bridge with the non-linear resistance 15 forming one arm, the input and output voltages being supplied to and taken from opposite diagonals of the bridge. The resistance 15 may have a positive or negative characteristic or may be thermally responsive in which case it may be heated by a separate electric heater coil energized from the control voltage or current. The element 15 may be a metal filament, e.g. tungsten or iron, in an inert gas, e.g. hydrogen, or it may be made of a silicious or ceramic material such as that known under the Registered Trade Mark " Thyrite." Where a source of D.C. is used, for controlling the resistance of the element 15, which is not uni-laterally conducting, the inductance 19 must be included in the control circuit so as to prevent interaction of the control and network voltages. The control circuit may comprise a rectifier valve, the anode current of which is controlled by variable grid voltage, and, in such case where rectifiers are used the inductance 19 may be omitted. The controlling voltage or current may be varied manually or in response to any controlling effect and the output voltage of the network may be used as grid voltage in the control of rectifier valves 5, 6, the anode voltage of which is in phase with the input voltage of the network. These valves may supply a load such as a motor 7, in which case the load current is controlled by varying the control voltage or current on the element 15, which voltage may be obtained from a current transformer 17 in response to current taken by any device 16. The voltage from the transformer 17 is applied to the element 15 through a full wave rectifier 18 and inductance 19. A number of separate load circuits 7, each supplied through grid controlled rectifiers 5, 6, may each be controlled from phase shift networks such as 11, the controlling voltages for which are obtained from a common variable control source.
