Title: A method of and means for obtaining the sum or difference and angular relation between quantities which may be represented by coplanar vectors
Filed: 1935-11-22
Abstract: 466,131. Electric signalling systems. ELLIOTT BROS. (LONDON), Ltd., and HAWKES, H. D. Nov. 22, 1935, No. 32398. [Class 40 (i)] [Also in Group XIX] In a system for obtaining the resul. tant of vector quantities the magnitude of the vectors are represented by alter nating currents anc the angles between the vectors by the phase relationship! of the currents, the currents being superposed in a single circuit including instruments for indicating the magnitude and direction of the resultant. As shown, a phase-shifting transformer 5, 6, 7 is supplied from a two-phase source 1 .. 4. A potentiometer 10 is connected across one phase 1, 2 and is adjusted in accordance with the magnitude of one of the vectors to be summoned. A potentiometer 9 is connected to the rotatable secondary winding 7 which is set in accordance with the angle between the vectors and the potentiometer is adjusted according to the magnitude of the second vector. The potentiometers supply the windings 11, 12 of a summation transformer 13 having a secondary circuit including a current meter 15 and the current coil of a power factor meter 14 the voltage coils of which are supplied from the mains 1 .. 4. The phase angle between the vectors is determined by measuring the phase angles of the secondary current relative to the supply mains 1 .. 4. If it is desired to measure the angle relatively to an arbitrary axis the power factor meter may be supplied from a source which is correspondingly phase displaced relatively to the supply 1 .. 4. The system may be used for determining the true velocity and direction of the wind from a moving vehicle, such as a ship. In this application, the winding 7, set in accordance with the direction of the wind, supplies one winding of an apparatus such as is described in Specification 405,043 and comprising two magnetic circuits linked by a shaped movable coil which is adapted to vary the linkage. The shaped coil is adjusted in accordance with the apparent wind velocity by current derived from an ancometer and the output from a winding or the second magnetic circuit may supply a circuit including an ammeter and a power factor meter. A current component proportional to the speed of the vehicle is also superposed by a transformer in the indicating circuit. Wind direction relative to the true north may be ascertained by interposing in the supply to the direction indicator a compass controlled phase shifting transformer. The Provisional Specification states that the scale of the direction indicator may be adjusted in order to determine direction relatively to the true north. Specification 413,804 also is referred to.

Title: Improvements in and relating to clutch mechanism
IPC: F16D43/21
Filed: 1952-12-22
Abstract: 719,768. Positive and overload clutches; converting rotary to oscillatary motion. GENERAL ELECTRIC CO. Dec. 22, 1952 [Dec. 26, 1951], No. 32438/52. Classes 80 (1) and 80 (2) [Also in Group VIII] A shaft is arranged to be connected to a driving means through a disconnectable coupling and an intermediary friction clutch the engaging pressure of which decreases as the torque increases. The invention is shown applied to a domestic washing machine. A member 54, Fig. 4, is slidable axially on an agitator shaft 5 to which it is splined, from the position shown in which dogs 55 thereon drivingly engage the output member 51 of an oscillator mechanism to a position in which the oscillator mechanism is disconnected and the drive is transmitted from a sheave 36 to a spin-dry basket shaft 6. The member 54 is moved, by means of a solenoid 62 acting through a spring 65 and a bell-crank lever 64, to the position shown and is moved to its other position by a spring 66 when the solenoid is de-energized by a cycle control switch (not shown). A resilient band 76, preferably of spring steel, is faced with friction blocks 75 which engage a cylinder 73 on the driving sheave 36. The band is formed with a free diameter greater than that of the cylinder 73 whereby it is normally stressed and urges the friction blocks into engagement. One end 77 of the band is radially directed and may be engaged by clutch members 80, 80.1 when the member 54 is slid upwardly. The members 80, 80.1 engage grooves 72.1 in a disc 72 keyed to the shaft 6. Under high torque conditions the force on the end 77 increases the stress in the band thus decreasing the engaging pressure of the blocks 75 and allowing slip to ease the load on the driving motor. In a modification a friction disc 84, Figs. 10 and 15, is urged axially into engagement with a radial face on a sheave 80 by a spring 94. The compression of the spring is increased to reduce the engaging pressure on the disc 84 during high torque transmission by means of cams 89 acting on surfaces 85 of a pressure plate 83. The cams 89 are carried by a member 86 keyed to a member 91 having projections 91.1 which may be engaged by pins 99 on an axially slidable clutch member 54.1. The pins 99 constantly engage slots in a member 95 keyed to the shaft 6. The agitator is driven by a continuously rotating motor through gears 44, 45, Fig. 3, a link 46, an internal gear sector 47 and a meshing pinion 48 on the shaft 50 of the member 51, Fig. 4.

Abstract: 432,347. Photographic and radiographic film-changing apparatus; shutters. LUBOSHEZ, B. E., 108, Station Road, Harrow, Middlesex. Nov. 22, 1933, No. 32620. [Class 98 (i)] Apparatus for removing a film-area from an exposure position and replacing it with another film-area without sliding contact between the film and its supporting surface comprises a cylindrical drum for the band of film and a device guided concentrically around the periphery of the drum for maintaining taut the band of film and for lifting a part of the band off the drum and replacing it with another part. As shown in Fig. 2, the film 8 with the sensitive emulsion inwards surrounds the drum 5 and roller 6 and is enclosed by the casing 1. For radiographic use, a fluorescent screen 9 is let in flush with the drum 5, and a mirror 10 is placed at 45‹ to the direction of the X-rays to enable the screen to be viewed from the side of the apparatus. Rotation of the arm 7 past the window 4 in the casing 1 replaces the film lying over the fluorescent screen 9, a shutter 12 carried by the arm preventing exposure during the changing operation. In modifications, the roller 6 may be replaced by a smooth-edged extension which engages or supports only the edge of the film ; or by two rollers which hold a slack part of the film between them. Also, a wheeled carriage carrying the roller 6 may replace the arm 7. X-ray fluorescent screens may be coated on either or both sides of the film-band, and the emulsion may also be coated on both sides of the film. In the form shown in Fig. 8, a longer length of film is accommodated, without increasing the gap between drum and roller, by passing the film over two rollers 6, 6 on the main arm 7 and then over an auxiliary roller 15 on an arm 16. A spring 17 maintains the loop in a taut condition. A larger number of rollers may be used to accommodate a much greater length of film. In the form shown in Fig. 10, the film is passed round the drum from two spools 18 which are biassed rotationally to maintain tautness. Several fluorescent screens 9 are located round the drum. By repeated rotations of the arm 7, a series of spaced exposures is obtained on the film, and pins 19 pierce the film to indicate the positions of the exposures. A fresh series of exposures may then be made in the same way after the drum has been turned so as to bring the next fluorescent screen into position opposite the exposure window, and this process is repeated, using each fluorescent screen in turn.

Title: Improvements relating to the production of organo-tin compounds
Inventor: POLKINHORNE HARRY
IPC: C07F7/22
Filed: 1952-12-24
Abstract: An alloy of sodium, zinc and tin which has been prepared out of contact with air is reacted with a halide of formula RX where R represents a hydrocarbon group containing at least 2 carbon atoms and X is halogen to produce a compound of formula R4Sn. The alloy may be prepared by fusing 10 to 20 per cent of sodium, 10 to 25 per cent of zinc and tin to 100 per cent in a rare-gas atmosphere, e.g. argon. It may be stored under xylene.  The reaction with the organic halide may be carried out in an inert liquid in which the xylene is soluble, e.g. ether.  The group R may be C2 to C5 alkyl or phenyl.  The R4Sn so prepared may be converted to R2SnX2 by heating with stannic halide.  Specified compounds so prepared include dialkyl and diaryl tin dihalides; dibutyl tin dilaurate and dibutyl tin maleate may also be prepared.  In an example an alloy of sodium, zinc and tin (14 : 16 : 70) is prepared by heating in argon and ground and stored in xylene.  The required amount is washed in ether and reacted with dry n-butyl bromide.  The residue is extracted with ether, dried and fractionated to give tetra-n-butyl tin.  Example 3 describes the conversion of this product (Bu4Sm) to dibutyl tin dichloride (Bu2SnCl2).

Title: Peak measuring voltmeter
IPC: G01R19/04
Filed: 1948-12-17
Abstract: 656,002. Current and voltage measurements. PYE, Ltd., and LAX, L. Dec. 17, 1948, No. 32766. [Class 37] The peak voltage of a pulsating wave-form is measured relatively to a predetermined level by applying the wave-form to a circuit which adds a D.C. component equal to the P.D. between the peak voltage and the average voltage, the resulting wave-form being fed to one of a pair of measuring devices, the other of which is fed with a voltage proportional to the predetermined level, the outputs being combined. A circuit for measuring the peak-topeak voltage is shown in Fig. 1. The waveform to be measured is applied to valve V1 to produce two outputs in anti-phase from resistances R2, R3, each of which is applied over condensers C1, C2, to diodes V2, V3, whose outputs are applied to valves V4, V5 to give an added output at A; the condenserresistance combination R6, C3 associated with the cathodes of diodes V2, V3 acts as D.C. restorer, the D.C. components in this case being equal and opposite for each of the anti-phase outputs. A similar circuit is shown in Fig. 2, where one of the anti-phase outputs of valve V1 is fed over separate condensers C10, C11, C11 to three diodes V20, V21, V22, whose joint outputs are fed to valve V5 to whose output is added the output of valve V4 fed with the output of two diodes V30, V31 fed with the other anti-phase output of VI; D.C. components added are again equal and opposite for both antiphase wave-forms. This arrangement is particularly suitable for waveforms in which the peaks are of short duration and the positive peaks are of shorter duration than the negative peaks. In Fig. 3 the peak voltage is measured from a predetermined level, e.g. the peak white voltage relative to the black level in a television signal. The signal applied at V1 appears at R2 and is applied over integrating circuit C4, R7 to valve V4 to give an output proportional to the average value of the signal plus the voltage due to the " nosignal current in V1; the signal at R2 is also fed over condenser C1 to a diode V2 having a circuit C3, R6 for restoring the D.C. component; diode V2 thus passes to valve V5 a voltage equal to the difference between the peak voltage and the average value of the signal applied to valve V5; if R7 is so adjusted that no reading is shown by voltmeter M when the input to V1 is at the black level, then for any other signal, the voltmeter M will read the value of the peak voltage relative to the black level.
