Title: Improvements in or relating to methods and circuits for initiating electric discharges
IPC: H02M1/04
Filed: 1956-07-13
Abstract: 804,841. Converting. SIEMENS-SCHUCKERTWERKE A.G. July 13, 1956 [July 28, 1955], No. 21759/56. Addition to 792,394. Class 38 (2). [Also in Group XL (c)] In the arrangement for initiating the discharge in an electric discharge vessel forming the subject of the parent Specification, the control alternating voltage UC has a substantially triangular voltage/time characteristic, Fig. 2. This voltage is developed across a condenser C by charging and discharging it alternately at a constant rate through transistors TL and TE respectively. The constancy of the charging current is obtained by the application of constant voltage between base and emitter of transistor TL from potentiometer P2 to the ends of which is applied a constant voltage U2. The discharge transistor TE is cut off by the negative base-emitter voltage developed across resistor R3 which carries the charging current. When condenser C is to discharge, the base-emitter voltage of transistor TL is reversed by the appropriately poled half-wave of an alternating voltage source UW. Rectifier G2 acts as a threshold limiter to prevent excessive base-emitter voltage; and rectifier G1 blocks off source UW during charging periods. When no charging current flows through transistor TE, constant discharge current flows through under the control of base-emitter voltage from source U3. The control pulses for the discharge vessel occur at instants ts, tf where the control alternating voltage UC equals in value the superimposed direct voltage Ur1. Pulses generated at points ts may fire the valves when used as rectifiers and those at points tf may fire the valves when used as inverters in a motor supply system. The instants of firing may be controlled together by variation of voltage Ur1. Where it is necessary for the discharge vessels when acting as rectifiers to fire at a different instant of each cycle from that necessary when they act as inverters, two condensers are separately charged and discharged through the same transistors to produce separate control alternating voltages, Figs. 4, 5 (not shown).

Title: Improvements in sustaining rotors for aircraft
IPC: B64C27/52
Filed: 1947-08-08
Abstract: 637,542. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21892. Convention date, July 7, 1942. [Class 4] A rotative winged aircraft having a sustaining rotor with flapping blades, is provided with a cyclic pitch control and a rotor hub which is freely tiltable and unrestrained by control connections so that it is free to assume an attitude on its tilting mounting dictated solely by the forces applied thereto by the blades and the reactions at the universal mounting pivots, and the rotor blades are connected to the hub by articulations including flapping pivots whose axes are offset from the hub axis towards the blade tips, wherein the cyclic pitch control mechanism is so arranged that the amplitude and phase of the cyclic pitch variation with respect to the hub dictated by the setting of the pilot's controls is unaffected by tilting displacements of the hub with respect to the airframe. The aircraft structure 3 is provided with trunnions 5 for supporting a gimbal ring 4 whereon the non- rotative hub member 6 is pivoted by trunnions 7. The axes of the trunnions 5 and 7 are preferably offset below the axes of the flapping pivots and in addition the axis of the trunnion 5 is offset forward of the rotor axis and the axis of the trunnion 7 is offset on the retreating blade side of the rotor axis. Bearings 9 mounted in the member 6, support the rotative hub member 8 which is driven by a pinion 11, a gear ring 12 mounted on a bearing 13, and over-running clutch rollers 14 cooperating with a drum 15 rigidly secured to the hub member 8. Each blade root 19, rotatably mounted on the hub.member 8 for pitch change, is extended inside the member 8 and provided with an arm 20 connected by a universally jointed link 21 to a swash plate 22 freely mounted at 24 on a spider 23 integral with the member 8. The swash plate 22 is extended into a depending arm 27 . provided with a bearing 28, the housing 29 of which is connected to one end of each of four Bowden control cables 30, each connected at its other end to a pilot's control member for controlling the blade cyclic pitch variations. The forces set up at the offset flapping hinges during cyclical pitch change always tend to tilt the rotating hub member 8 to a position where the tilted hub axis lies on or close to the rotor lift line, thus reducing blade flapping to a minimum. Specifications 393,976 and 410,532 are referred to.

Title: Light modulating system
IPC: H04B10/00
Filed: 1946-07-23
Abstract: 643,210. Light valves. FARNSWORTH TELEVISION & RADIO CORPORATION. July 23, 1946, No. 21944. Convention date, Aug. 13, 1945. [Class 40 (iii)] In a light-modulating system in which mechanical waves are propagated through a light valve comprised of an elastic transparent medium to cause diffraction of a light beam, the mechanical waves are produced by a carrier oscillation which is amplitude-modulated by a sub-carrier oscillation, itself amplitude-modulated by a modulation signal. The light valve comprises a container 2 (Fig. 1) formed with two glass sides 4, 5 and filled with a suitable liquid (e.g. water, heptane or butyl bromide), through which mechanical waves are propagated by means of a piezo-electric crystal 6 energized by a carrier oscillation (e.g. 10 Mc/s.) source 13 which is amplitude-modulated in 14 by a subcarrier (e.g. 1 Mc/s.) source 11 itself amplitudemodulated in 12 by an audio-frequency signal source 10 which may have a maximum frequency of about 10 kc/s. The diffraction grating effect resulting from the propagation of the mechanical (i.e. compressional) waves in the liquid of the cell is employed to control a parallel light beam from source 25 in accordance with the modulated sub-carrier and, to this end, the diffracted component of the light which emerges from the light valve is separated from the emergent undiffracted component by means of a first series of opaque bars 27 separated by spaces 28 of the same width as the bars 27 and a similar series of opaque bars and spaces 30, 31, separated from the first series by a distance, determined by calculation, so that light of the first diffraction order only is permitted to pass through the spaces 28 and 31 whilst the transmission of undiffracted light is prevented. The emergent diffracted light is then collimated by lens 35 and employed for transmission to a distant receiver. Instead of positioning the two series of opaque bars on the emergent side of the cell one series may be positioned on the incident side. The undiffracted emergent light may be utilized for transmission instead of the diffracted light by shifting the bars 30 to either side by a distance equal to their width. In a receiving system for use with the modulating system provided by the invention (Fig. 5, not shown) the received modulated light is transformed into an electrical signal by means of a photo-electric cell, the output from which is detected to recover the modulation signal and then amplified and fed to a loudspeaker. In an application of the invention to multiplex signalling (Figs. 6 and 7, not shown) three light valves, each energized by a common carrier oscillation but by different sub-carriers, each of which is modulated by a different audio signal, control a single light beam, the three modulation channels of which are separated at the receiver by electric filter means.

Abstract: 969,882. Dispensing liquid. SCHEIDT & BACHMANN G.m.b.H. May 31, 1963 [June 1, 1962], No. 21952/63. Heading A4T. [Also in Division G4] A liquid fuel dispensing pump having a quantity pre-setting mechanism brought into operation by the insertion of coins to the value of fuel required has means for automatically throttling the delivery or liquid shortly before the end of the delivery operation, such means comprising a feeler lever 3a which is held clear of a cam 1 by an electromagnet 6 until released so as to be under the control of the cam and operate the shut-off valve 7 during a fixed period when the last amount of fuel is being dispensed. The cam is mounted for rotation by counting drums 2a, 2b, 2c and adapted to close a switch 15 of a totalizer once every revolution of the drum 2c, the drums being driven from a flowmeter. Shortly before the last revolution of the drum 2c is due to commence in a dispensing operation, the totalizer signals to the electromagnet to withdraw its armature 5 thereby allowing the spring-urged feeler arm 3a of the bell-crank lever 3a, 3b to step down the profile of the cam, first to partially and then completely close the valve 7. When the fuel has been dispensed, the counting drum is returned either manually or automatically into a zero position, thus operating the cam and raising the bellcrank lever so that the arm 3b, which is provided with an inclined upper surface 3c, pushes past the armature 5 into its locking position.

The 16a ,17a -diols and their acetals and ketals may be interconverted by standard procedures. The nature of thepyrazolo products when R1 is not hydrogen, i.e. whether they are 11- or 21-isomers, depends on the nature of the hydrazine and on whether a 2-hydroxymethylene or 2-alkoxymethylene starting material is used. The isomers may be separated by chromatography. The N-alkyl-[3,2-c]pyrazoles may also be prepared by direct alkylation of the N-unsubstituted compounds.  N-acyl compounds are prepared by conversion to 21-tetrahydropyramyl ethers, N-acylation, and removal of the ether group.  Acylation of N-unsubstituted 21-diols gives N,21-diacylates, from which the N-acyl group may be preferentially hydrolysed. 21-Unsubstituted compounds are prepared by standard methods via the 21-mesylates and 21-iodo compounds, N-unsubstituted compounds being protected by conversion to the N-carbamoyl derivatives.  21-Fluoro and -chloro compounds are prepared from the 21-mesylates and alkali metal fluorides or lithium chloride. 21-Phosphate esters and their salts are prepared from the 21-iodo compounds by standard methods.
