Title: Improvements in mechanical devices for amplifying small linear displacements
IPC: G05D23/02
Filed: 1930-08-30
Abstract: 361,451. Thermostats. ERB, A. C. J., 17, Rue Dupleix, Paris. Aug. 30, 1930, No. 25988. Convention date, Sept. 13, 1929. [Class 64 (ii).] An amplifying device for measuring and detecting small displacements comprises two relatively movable members and a blade or like oscillating member freely supported between the members on knife edges or other fulcra, the axes of the knife edges &c. being substantially perpendicular to the direction of displacement of the members. The movements of the oscillating member may be indicated or utilized to operate a switch to regulate other apparatus. The invention, in its application to a thermostat comprises an expansible rod T, Fig. 2, with a knife edge or needle point B bearing on an oscillating blade L supported by a knife edge or needle point A on a fixed member. In the arrangement in which the point of needle B is above the point of needle A the blade L may be extended to form an indicating pointer. The sensitiveness of the instrument may be varied by altering the distance between the points A, B as shown in Fig. 15, or by making the blade flexible and applying a force to the needle. In the case in which the needle point B is below the needle point A the blade L is caused to tilt abruptly and serves as a quick make and break device or switch as shown in Fig. 7. The movement of the needle B due to the thermal expansion of its associated bar causes the blade to tilt, the movement being assisted by means of a spring S. In order to prevent displacement of the blade on its needles or knife edges the imaginary axis of rotation is extended to form trunnions t<1>, t<2>, Fig. 9, which extend between upright guides g<1>, g<2>. Various constructional forms of thermostats are described in the Specification. In the simplest form, Fig: 12, a forked member is provided with branches 21, 22 of metal having different coefficients of expansion, the blade being supported at the free ends. In Fig. 13, the device is constituted by a bi-metallic strip 23. In a form shown in Fig. 17, the expansion of a liquid in a closed member c causes the displacement of a piston connected with the rod T, 'the knife edge A being adjustably mounted on a slide on the base. For differential measurement two chambers may be provided each operating a piston and rod supporting the blade. In another form, Fig. 20, a tube 34 is provided with heat-radiating flanges to increase the sensitiveness to variations. Instead of a tube bi-metallic strips may be employed.

Title: Apparatus for modulating brake pressure
IPC: B64C25/48
Filed: 1957-08-19
Abstract: 817,854. Fluid pressure brakes. GOODYEAR TIRE & RUBBER CO. Aug. 19, 1957 [Nov. 19, 1956], No. 26071/57. Class 103 (1). Apparatus for modulating the pressure applied to aircraft brakes comprises a source of pressure fluid, a pilot-controlled valve for applying the fluid to the brakes and a pressure regulating valve adjusted by means controlled by the aircraft speed relative to air for modulating the pressure applied by the pilotcontrolled valve. Pressure fluid is supplied from tank 9 via pump 10, pipe 11, and pressure regulator valve 12 to the pilot's control valve 13 operated by a pedal 20 to connect either the supply pipe 16 or exhaust pipe 18 to a pipe 17 and cylinders 6, 6<SP>1</SP> of a disc brake. Air pressure due to aircraft speed, acts through pitot head 2 to operate bellous-diaphragm 4 which through linkage 4a, 21, 25 moves bellows diaphragm 24 to change the pressure in capsule 23 and chamber 31 of cylinder 27, the other chamber 30 of cylinder 27, separated from chamber 31 by diaphragm 29, being kept at a constant pressure which can be adjusted by valve 41 graduated to represent the aircraft's gross weight, capsules 32, 33 and diaphragm 29 support a rod 34 connected by linkage 35, 38 to the plunger 37 of the regulator valve 12. Changes in aircraft speed produce changes in pressure in capsules 3 and 23 and chamber 31, resulting in movement of diaphragm 29 until pressure in chambers 30, 31 equalize, consequential movement of rod 34 adjusting regulator valve 12 to supply fluid at a pressure for the highest braking efficiency. The pressure ratios between capsules 3 and 23 and the linkage ratio between links 35 and 37 may be changed by nuts 44, 48 on rods 43, 47 pivoted to levers 25, 46 respectively, the nuts being graduated to represent the lift coefficient and runway coefficient of friction, respectively, and are adjusted by the pilot. Antiskid apparatus 51, 50, 52 may be used to operate a valve 53 to release fluid from cylinders 6, 6<SP>1</SP> on skidding.

Title: Improvements in and relating to the folding legs of bedsteads
IPC: A47C19/12
Filed: 1933-09-23
Abstract: 431,125. Folding bedsteads. MALICKY, J. T., 42, Schanzstrasse, Vienna. Sept. 23, 1933, No. 26285. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 24, 1934]. [Class 52 (ii)] The folding legs of a bedstead are adapted upon lifting the bedstead to fall under the action of gravity to a position for use and held firmly in that position by struts. The legs e are pivoted to the bed frame at f and are engaged by the ends of struts g. which are pivoted at h. The end of each strut is bent over at i to apply a frictional grip to the leg and when this portion abuts against the cross piece k of the legs e, these are held firmly against collapse. The grip at i is released by lifting the struts and the legs can then be moved back to the folded position. In a modification, the struts at the pivot end are extended to provide a projecting end which engages the bed-frame at the extreme position and prevents any further swinging movement of the strut.

Title: Improvements in and relating to magnetic cores
IPC: H01F27/245
Filed: 1948-10-08
Abstract: 673,821. Making transformers cores; angular bending. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 8, 1948 [Oct. 18, 1947], No. 26292/48. Classes 83 (ii) and 83 (iv). [Also in Group XXXV] A method of making a transformer core comprises bending a number of laminations precut to different lengths so that a series of lap joints are produced, which joints consist of a number of butt joints in a recurring pattern occupying a short length in comparison with the core thickness. A three-phase transformer core comprises three laminated legs 1 having bent end portions 4 forming the end yokes, which portions are magnetically connected by inserts 5. The yokes are removable from the core legs so as to allow the assembly of preformed coil windings on the legs, the joints 3, 6 between the yokes and legs and the yokes and inserts respectively being of the so-called irreversible assymmetrically recurring lap type. A four-way version of this type of joint is shown in Fig. 4 showing each of four sets of laminations lapped over the preceding set by an equal amount in the same direction. The fifth set is lapped all the way back to the same plane as the first set and the process repeated with subsequent sets of laminations. With this type of joint, at any particular plane, only a small proportion of the core width is actually comprised by joint. One method of bending the yoke members 4 is shown in Fig. 6. Sets of laminations precut to the required lengths are assembled in a jig and the entire jig is moved upwards, by means of a rod 25, between two fixed rollers 26 so as to bend the laminations as required, these being finally annealed. Two yoke portions 4 are thus formed simultaneously. Specifications 620,953 and 642,450, [both in Group XXXV], are referred to.

Abstract: 686,202. Control of D.C. motors. BROWN BOVERI & CIE AKT.-GES. Oct. 31,1950 [Oct. 31. 1949], No. 26585/50. Class 38 (iii) The armature M of an electric motor and its field winding are supplied through separate converters (not shown) the control means of which are so inter-related that before each field reversal, the armature current is stopped, and, after reversal of the field has been effected, the armature current is restored with the phase position of the control impulses applied to the main current converter in correspondence with the reversed excitation voltage. Means are provided for obtaining a voltage u at terminals g<SP>1</SP>, g<SP>2</SP>, which, by way of grid control of the excitation current converter, effects a temporary increase in excitation voltage and so increases the rate of change of field during the reversal operation. As shown, the voltage u is the difference between the voltages u<SP>1</SP> and u<SP>2</SP> which are respectively proportional to the excitation current and the excitation voltage. If the excitation voltage is suddenly reversed the voltage u, cannot quickly follow this change and the resultant voltage u reaches a considerable value. In Fig. 2 (not shown) the voltages u<SP>1 </SP>and u<SP>2</SP> are applied to a control winding of a saturable reactor and the voltage u is derived from a rectifier connected across a resistor in series with an A.C.-excited winding of the reactor.

Abstract: 968,565. Control of D.C. motors. CONVEYANCER - RAYMOND Ltd. July 4, 1963 [July 11, 1962; Oct. 26, 1962], Nos. 26652/62 and 40588/62. Heading H2J. A material-handling truck having traction motor A is driven forwardly when contactor Fc is energized through contacts F and RL2/1. Actuation of a spring-loaded safety switch SW, by engagement with an object external to the truck, energizes relay RL2 to stop the forward drive. Closure of contacts RL2/2 energizes relay Rc for reverse drive until the controlling handle is returned to the neutral position. This opens contacts F to de-energize relay RL2 so that contacts RL2/2 open to de-energize relay Rc. In another arrangement, actuation of the safety switch energizes relay RL2 and charges capacitor C1, forward motion of the truck being halted. The reverse contactor Rc is energized by contacts RL2/2. Reverse movement of the truck permits the safety switch to re-open, the opening of the contacts of the relay RL2 being delayed, however, whilst capacitor C1 discharges, so that the truck is propelled clear of the obstruction before the reverse contactor is de-energized. The controller must be returned to the neutral position before the truck is again driven forwardly. In a further modification, the truck is reversed through a predetermined distance after operation of the safety switch. A counting device coupled to the traction motor may be used for measuring the distance.
