Title: A switch circuit for electric heating appliances, more particularly hotplates or boiling plates
IPC: F24C15/10
Filed: 1956-09-28
Abstract: 804,453. Switching arrangements for heating resistors. JACKSON INDUSTRIES, Ltd. (Fischer, K.). Sept. 28, 1956, No. 29724/56. Class 38 (4). [Also in Group XI] An electric heating appliance comprising a plurality of heating elements has one element in the form of a supplementary element which can be switched on manually to accelerate the initial heating and cut out automatically by a heat-operated switch after a predetermined time, the supplementary element also being available for manual series and/or parallel switching operations. An electric cooker has three heating elements X, Y, Z, the element Z forming a supplementary element associated with which is a bimetallic switch S, the heater coil d of which can either be connected in series or in parallel with the element Z. Operation of a manual switch S1 to the " high heat " position connects line P1 to connections e, f and line P2 to connections g, h. In this position elements X, Y are in parallel giving the highest heating condition for the hot-plate 1, the supplementary element Z also being in parallel over the bimetallic switch S to give rapid initial heating of the hot-plate. After a predetermined timesay seven minutes-the switch S operates to open its contacts a, b to remove the element Z from circuit, the hot-plate then continuing to operate in the " high heat " manner with the elements X, Y in parallel on the supply. The contacts a, b remain open due to their position below the hot-plate, where they are influenced by the heat from the hot-plate. In Fig. 6 the switch S and the manual switch S1 are each shown attached to one of the legs 3 supporting the hot-plate 1. Operation of the manual switch S1 to other heat positions gives various single, series and/or parallel connections of the elements, the supplementary element Z being used in the " low heat " position where all three elements X, Y, Z are in series across the supply. With such a connection the heat developed in the switch heater coil d is insufficient to open contacts a, b, thus allowing the element Z to remain in circuit. After rapid initial heating, should the manual switch S1 be operated to other heat positions the bimetal switch returns to a condition where it will again afford rapid heating if desired.

Title: Pressure gauge
Inventor: SADLER MICHAEL
IPC: G01L9/00
Filed: 1965-07-14
Abstract: 1,116,581. Measuring pressure electrically. ROLLS-ROYCE Ltd. Feb.2, 1966 [July 14, 1965], No.29957/65. Heading G1N. A pressure gauge comprises a Piezo-electric crystal 7 (Fig. 1 Fig.2 (not shown) of lead zirconate, fixed to a metal diaphragm 11 and to a lead backing bar 6 by electrically conductive cement. Pressure to be measured is applied to the diaphragm by a metal bar 10 integral therewith. The backing bar 6 is supported, by insulating washers 4, 5, within an insulating sleeve 3 which lines a cylindrical brass housing 2. The diaphragm has a flange 12 electrically connected to the housing 2 and is sufficiently stiff to locate the crystal and the bar 10 permitting free though limited movement of the bar 10 toward and away from the backing bar 6 and resisting all other movements thereof. The bar 10 is mounted within seals 13 and has a face 14 to which the pressure, for instance a shock wave, is applied. The space 15 between the sleeve 3 and bar 6 is filled with plastic ceramic material or alternatively synthetic rubber Fig. 2 (not shown) to damp compression or tension waves travelling in the bar 6. A meter or display unit connected between the bar 6 and cylinder housing 2 indicates pressure. In a further embodiment Fig. 3 (not shown), acceleration of the gauge which would produce inaccuracies is compensated for by the provision of an annular Piezo-electric crystal 7" which surrounds the sensing crystal 7', both crystals being sandwiched between two diaphragms. The co-planar end faces of the crystals are electrically connected and have opposite polarities whereby any output from the sensing crystal due to acceleration of the gauge unit is cancelled out. An electrostatic shield in the form of a brass sleeve (24) Fig. 2 (not shown) may be provided around the damping material if the latter is neoprene.

Title: Improvements in or relating to liquid pressure braking systems for vehicles
Inventor: PARNELL FRANK GORDON
IPC: B60T8/26
Filed: 1960-09-01
Abstract: 936,495. Braking systems. AUTOMOTIVE PRODUCTS CO. Ltd. June 22, 1961 [Sept. 1, 1960], No. 30194/60. Class 103 (1). A liquid pressure braking system for a vehicle includes a master cylinder 10 or other liquid pressure source, motor cylinders 16, 17 in which liquid pressure from the source acts to apply, respectively, front and rear wheel brakes 12, 14, and means operated when the rate of deceleration of the vehicle exceeds a predetermined value for reducing the pressure in the motor cylinders 17 relative to that in the motor cylinders 16, the said means comprising a plunger 28 having a face of smaller area exposed to the pressure in the pressure source and an oppositely directed face of larger area exposed to the pressure at the rear brakes 14, a non-return valve 35 being provided in a passage 33 through the plunger to prevent flow of liquid through the passage from the pressure source to the brakes 14 and there being means 38 for holding the valve 35 unseated and which is rendered inoperative by deceleration responsive means when the predetermined rate of deceleration is exceeded. As shown, when the pedal 11 is operated, liquid is displaced through conduits 18, 21, 22 and 24 to operate the motor cylinders 16, 17 and to apply the brakes; liquid is also displaced through a conduit 44 to act in the space 43 on a plunger 41 and to compress a spring 42 to hold the plunger 28 against a stop 39, a ball valve 35 being thus held off the seat thereof by a pin 38 and the pressure acting on the rear wheel motor cylinders 17 being the same as that acting on the front wheel motor cylinders 16. As the thrust on the pedal 11 is increased, the pressure in the motor cylinders 16, 17 and the space 43 is also increased, the pressure in the space 43 holding, through the medium of the spring 42, the plunger 29 against the stop 39. When the braking applied is sufficient to cause the rate of deceleration to exceed a predetermined value the eccentrically pivoted disc 47 of the means 45 is caused to swing about a horizontal axis, which is transverse to direction of movement of the vehicle, to close the conduit 44 and thus prevent further rise of pressure in the space 43. The further increase in thrust on the pedal 11 results in an increase in thrust on the face of the plunger 28 in the space 34 so that the plunger moves away from the stop 39 to allow the ball valve 35 to close. The pressure acting on the motor cylinders 17 therefore increases at a rate less than does the pressure acting on the motor cylinders 16. In a modification, the valve 23 comprises a ball valve 35 and a plunger 28 which abuts the piston 51 of a vacuum servomotor 52 which when energized holds the plunger against the stop 39 and is connected through a control valve 54 to a vacuum reservoir 55 or to atmosphere, the valve being operated by deceleration responsive means consisting of a suspended arm carrying a weight 58 and connected by a link 57 to the plunger of the valve 54.

Abstract: 1345234 Spray nozzles BALTIMORE AIRCOIL CO Inc 28 June 1971 [19 May 1971] 30272/71 Heading B2F [Also in Division F4[ In an evaporative heat exchanger, a plurality of nozzles 23 are provided to spray water to be cooled into a venturi of circular crosssection, the nozzles 23, each of which is so constructed and orientated as to produce a fan shaped spray, being circumferentially spaced around an annular manifold 35 located adjacent the venturi inlet 32. The water sprays serve to entrain a flow of cooling air through the venturi. Cooled water is collected in a sump downstream of the venturi; the air leaves the heat exchanger through mist eliminators which remove entrained water droplets therefrom. In an alternative embodiment (see Figs. 4 and 5) a tree-type manifold system comprising a central manifold (39) from which spaced pipes (40) of different lengths extend in opposite directions is used in place of the annular manifold. The sprays may either be normal to the longitudinal axes of the pipes (see Fig. 4) or they may be inclined with respect to these axes (see Fig. 5), the orientation being different in different quadrants of the venturi throat. In a further embodiment (see Figs. 6 and 7) a single nozzle (41) having circumferentially spaced holes (42) each capable of producing a fan-shaped spray is employed.

Title: Automatic control of aircraft in curved flight
IPC: G05D1/04
Filed: 1934-10-22
Abstract: 444,827. Automatic control of a body in motion. BOYKOW, J. M., 2A, Fontanestrasse, Lichterfelde-West, Berlin. Oct. 22, 1934, No. 30295. Convention date, Nov. 10, 1933. [Class 38 (iv)] The automatic control of aircraft in curved flight is effected by a controlling member a1 attached to a disc s constituting a stabilized platform and set in rotation in a direction and at a speed corresponding'to the desired curve. The controlling member al actuates simultaneously two regulating devices e<1>1, e<1>2 which are rotatable about two axes perpendicular to each other and fixed relative to the aircraft. These devices control respectively the rudder s and elevator H so that the curve takes place in a horizontal plane. A second controlling member a<2> parallel to the transverse axis of the aircraft may adjust a regulating device e<1>3 controlling the ailerons Q to maintain lateral stability. The disc s is preferably stabilized by a gyroscopic pendulum. A gyroscope rotating on an axis b1 transverse to the craft is mounted on a precession axis v longitudinal to the craft and curved flight is produced by a torque producer m4 on the latter axis which may be energized as desired by the pilot by means of a voltage divider T to determine the speed and direction of rotation of the disc 8. This torque producer may also be controlled by a magnetic compass and electrolytic element E to maintain a compass course set by rotating a hand wheel u. The controlling member a1 operates two bows l1, l2 coupled to the regulating devices e<1>1, e<1>2 respectively which are constituted as electrolytic resistances and control the excitation of windings w<11>1, w<11>2 of torque producers operating fluid pressure servomotors actuating the rudders M, S respectively. The controlling member a2 is similarly arranged to vary the excitation of the windings w<11>3 of a torque motor governing a servomotor operating the ailerons Q. Independent control of the rudders and ailerons is also provided by excitation windings w<1>1, w<1>2, w<1>3. Control of curved flight may be obtained also by continuous rotation of the hand wheel u. The compass control may be relatively weak so that after completion of a curve the craft will automati. cally resume its compass course. By rotating the casing of the regulating device e<1>1 helical flight at any desired angle of descent or ascent may be achieved. Similarly by adjustment of the casing of the regulator e<1>3 the craft may be given a constant tilt about its longitudinal axis or by connecting the voltage divider T to this casing as by a Selsyn coupling J, J<1> the tilt may be proportioned to the curve in the course. The intensity of the control is determined by resistances r1, r2 and electromagnetic switches operable from a pilot switch t4 are provided whereby these resistances may be short circuited to stiffen up the control at will. Switches t1 .. t3 are provided to enable any desired control to be eliminated.
