Title: Improvements in means for introducing gas into a liquid
IPC: C10L3/04
Filed: 1931-10-12
Abstract: <PICT:0375164/IV/1> In a device for introducing a gas into a liquid in which it is soluble, especially applicable for introducing acetylene into acetone in an acetylene reservoir, small quantities of gas are introduced intermittently by means of a valve adapted to open and close automatically.  As shown, a chamber C interposed in the gas supply pipe A has a restricted inlet B and an outlet L controlled by a spring-loaded valve E.  When the valve has been opened by the rise of pressure in the chamber, the gas passes by way of passage G and pipe H to the liquid reservoir.  Gas also passes to the back of the valve through a passage I so that as the pressure falls in the chamber the valve automatically closes, and remains closed until the pressure is again built up in the chamber.

Title: Wobble plate flow-rate measuring
IPC: F15C3/16
Filed: 1976-07-08
Abstract: 1523215 Flow-rate measurement NISSAN MOTOR CO Ltd 8 July 1976 [8 July 1975] 28426/76 Heading G1A In a "wobble plate" flow-rate measuring device fluid flows via an inlet channel 4 into a cavity 11 and out via one of a pair of discharge channels 14a or 14b. The flow-path depends upon the position of an elongated member that is pivotally supported at 13, as shown, and defines two chambers. The action of fluid flowing into the left hand chamber of the Fig. 1 type configuration causes a pressure build up on the lower part of the plate relative to the right hand chamber that eventually causes the member 7 to swing in an anti-clockwise direction. Thus the member 7 will swing back and forth with a frequency proportional to the fluid flow-rate. This frequency is monitored by a light emitting diode 15 and a phototransistor 16 positioned as shown, on either side of transparent flat plates 2 and 3. The phototransistor's output may be processed to provide an analogue or a digital signal.

Abstract: 1,149,627. Drafting rollers. C. F. ESPINOSA. 24 June, 1966 [29 June, 1965], No. 28428/66. Heading D1D. Variations in the diameter of the threads being drafted are produced in a spinning frame including a primary drive shaft 4 and a plurality of subsidiary drive shafts 1, 2 and 3 which rotate in the same direction as the primary drive shaft 4. The primary drive transmission couples with the subsidiary shafts 1, 2, 3 through a free-wheel gear 9 so as to rotate them at a predetermined speed. A secondary drive transmission includes a clutch 16 which, when engaged, couples the primary drive shaft 4 with the subsidiary drive shafts 1, 2, 3 so as to rotate them at a higher speed independantly of the primary drive transmission by free rotation of the free-wheel gear 9. A control means 18, 19, 20 couples the clutch at predetermined intervals to vary the speed of rotation of the shafts 1, 2, 3 and thus the draft of the thread. The control means includes a programming circuit 18 to produce a predetermined series of clutch coupling and uncoupling periods; a disturbance circuit 19 produces variations in preceding clutch coupling and uncoupling periods at the end of a predetermined number of working cycles of the programming circuit; a second programmer 20 can act on all time constants, e.g. by variation of its input voltages.

Title: Improvements relating to electrical remote control and signalling systems
IPC: H02J13/00
Filed: 1926-06-08
Abstract: 281,988. Siemens Bros. & Co., Ltd., and Humphries, H. E. June 8, 1926. Drawings to Specification. Selective distant control systems; tell-tale apparatus.-Relates to a system for controlling and supervizing apparatus located at a plurality of remote stations connected across common control and supervisory line wires. The system described is identical with that described in Specification 280,254, but the claims relate to the means for initiating the transmission of supervisory signals. Associated with each apparatus unit is a. differentially wound relay which is normally energized and is de-energized when the unit changes its condition to mark a switch which hunts up to the marked contacts and initiates the transmission of a signal characteristic of the operated unit. When the signal has been despatched the relay is re-energized to establish normal conditions. In the event of a fault, e.g. apparatus unit signalling contacts out of adjustment, the hunting switch is not marked and in consequence operates up to a predetermined contact to initiate the transmission of an alarm signal. The hunting switch remains in the alarm position until released by a special signal or a signal for controlling an apparatus unit transmitted from the control station, when if the fault at the substation still exists, a further alarm signal is recorded at the control station. An attendant at the substation may also check for the successful clearance of a fault by operating a special key. Specifications 290,485, 280,486, 281,987 and 293,253 also are referred to. The Provisional Specification refers to Specification 230,291, [Class 40 (iv), Telephones &c.].

A radio reflector of paraboloidal dish form, for use in a radio telescope, comprises two intersecting sets 14 and 15 of opposite-handed equiangular spiral frames extending between circular frames 12 and 13 close to the centre and at the periphery of the reflector. The frame and ring structure carries supports for, or itself supports, a wire mesh or metal sheet reflector surface 16. Each spiral member 14 or 15 may consist of an inner and outer tube the distance between the two decreasing towards the frame 13. The tubes may be of light alloy and because the spirals are equiangular a standard die-cast X jointing member (Fig. 4, not shown) to which the tubes are screwed may be used at each joint. Although the tube external diameter is the same throughout the structure in order to make use of these standard jointing members the gauge of the tubes may decrease towards the periphery of the structure. Certain of the jointing members may be provided with additional coupling arms for the attachment of bracing members such as that shown at 20. The spacing between the spiral frames in the outer regions of the structure may be filled in with supplementary spiral members 17 extending only part of the way to the centre of the structure. In one mounting arrangement the circular frame 12 forms the base of a frustoconical hub frame 10 by which the structure is rotatably mounted on support axle framework 21, 22. This framework is extended as aerial supporting mast 24 and is capable of movement about axis 23 for elevation adjustment. A counter-weight 25 (also seen in Fig. 3, not shown) balances the reflector. Means are provided for continuously rotating the dish on axle 21 as the gyroscopic effect steadies the structure against wind gusts and temperature variations. A simpler mounting in which it is not possible to rotate the reflector is described with reference to Fig. 5 (not shown). Specification 731,665, [Group X], is referred to.

Abstract: 481,760. Sealing metal to insulating - materials. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1936, No. 29556. Convention date, Jan. 17. [Class 36] In a gas-tight joint between a metal member forming part of a low-pressure container and electric insulation material moulded thereon, the metal member is so shaped that gas leaking through or over the surface of the insulation material reaches the surface of a _portion of the metal member projecting into the insulation material and passes over said surface to a chamber intermediate the high and low pressure sides of the joint from which chamber the gas can be exhausted. In the construction shown in Fig. 1, an insulator for carrying a conductor 35 into a discharge tube comprises metal rings A, B connected in gastight manner respectively to the conductor 35 and the body of the discharge tube and separated by a moulded mass of vitreous or other insulating material. The rings A, B are formed with pairs 2, 3 and 12, 13 of coaxial projections embedded in the insulating material, annular chambers 7, 17, free of insulating material, being'formed between the pairs of projections by rings 8, 18 which are shrunk on the inner projections and are of such external diameter as to leave small channels 10, 20 between them and the inner walls of the projections 2, 12. The chambers 7, 17 are continuously exhausted through apertures 23, 24 to remove gas which may leak into the insulation, such gas traversing the surfaces of the projections to reach the chambers 7, 17. To increase the leakage path the projections are grooved. In modified constructions the exhausting chambers are formed within the projections. Fig. 5 shows such a construction, the exhaust chambers 7, 17 being formed within the projections 2, 12 which are built up from a number of superposed grooved rings having spaces such as 45, 44 between their outer edges through which leakage gas may pass to the exhaust chambers. The superposed rings may be so formed that spaces between them occur at the inner edges 'of the rings also.
