Title: Process for separating gas mixtures, more especially air or other difficultly liquefiable gas mixtures
IPC: F25J3/04
Filed: 1924-02-04
Abstract: 236,603. Mewes, R. F., and Mewes, R. K. E. Feb. 4, 1924. Separating gaseous mixtures by liquefaction.- In the separation by liquefaction of mixtures of permanent " gases, an excess of the low boiling point substance from the separator column is liquefied in a condenser, and a corresponding excess of the high boiling point substance is vaporized, the excess of vapour so produced being in part re-liquefied by heat exchange in another condenser with a part of the liquid so produced, and the remainder of the liquid returning to the separator column. Pure, pre-cooled air is passed into the separate column through a pipe 3 under pressure, and is washed by nitrogen. Highly compressed air or nitrogen after passage through a heat exchanger flows through a pipe 65 which is led through the oxygen vaporizer 8 and as a coiled portion through the upper part of the column finally delivering its contents, expanded through a valve 66<a> into the middle of the column. The liquid oxygen in the base is delivered through a valved pipe 69 into the condenser 12, the liquid being vaporized and led off by the outlet 5. Nitrogen rising in the column liquefies in passages 70 and is delivered into a chamber 71 from which a part is fed back into the column through overflow pipes 72. Another part flows into a chamber 73 in which its vapour passes off under pressure through pipes 75 while the liquid flows through pipes 74 and after expansion through a valve 76 is led around a supplementary oxygen condenser and rectifier 78, finally passing away through an outlet 7. The oxygen vapours rising through pipes 80 are rectified in the condenser 78, the liquid oxygen flowing back through these pipes while the nitrogen vapour passes into the column through pipes 79.

Title: Improvements in or relating to a method and apparatus for making plastics hose
IPC: B29C53/82
Filed: 1970-01-21
Abstract: 1294563 Moulding tubes B F GOODRICH CO 21 Jan 1970 [21 Jan 1969] 3007/70 Heading B5A [Also in Divisions B8 and F2] A helically reinforced tube is made by helically winding a heat softened thermoplastic ribbon having a central core of stiff material over a pair of rotatable mandrels, uniting adjacent turns of the wound ribbon in axial abutment, and continuously advancing the tube thus formed from the mandrels. In one embodiment (see Fig. 1) a cored thermoplastic ribbon 14, extruded from a twin-feed crosshead 12, is helically applied over an upper mandrel 15, rotated by a motor 16 and a lower mandrel 17. The lower mandrel is shorter than the upper mandrel and is freely rotatably mounted at an adjustable angle to the upper mandrel in a frame 18 so as to impose the desired forward motion upon the wound ribbon. As the ribbon is fed to mandrel 15 its turns are united in axial abutment due to the soft state of the ribbon. This may be assisted by a spring-biased roller 24, the degree of compression and thus the thickness of the wound tube being determined by a collar 15a carried by the mandrel against which the roller abuts. The helically wound and united strip leaves mandrel 17 and is supported by mandrel 15 during which time it gradually distorts into a circular cross-section, the tube thus formed finally being supported against distortion after it has left mandrel 15 by a pair of rollers 22. In a second embodiment (see Fig. 6), the lower mandrel is disposed parallel to the upper end and is provided with longitudinally slidable surface slats 53 which are reciprocated cyclically by a core-slot 57a located in a fixed core 54 of the mandrel. In this way the requisite forward movement is given to the wound ribbon without having to resort to a skewed lower mandrel.

Title: Control devices for high frequency electrical oscillations
IPC: H01J17/04
Filed: 1942-03-09
Abstract: 589,023. Wireless transmitting and receiving apparatus ; discharge appasatus. COOKE, A. H., SKINNER, H. W. B., WARD, A. G., and WRIGHT, C. S. March 9, 1942, No. 3056. [Classes 39 (i) and 40 (v)] A device for the control of high-frequency power comprises a cavity resonator, having input and output couplings to a transmission line or wave guide and enclosed partly or wholly within a gas-filled tube which on the occurrence of a glow discharge damps the resonator and thus reduces the flow of energy along the line or guide. The device may be used in a combined radio transmitter and receiver, such as a radio location apparatus, for protecting the receiving apparatus from the high voltage pulses present in the transmitter. As shown, the resonator is formed by sealing copper plates 20, formed for example as in Specification 589,022, between sections of glass tubing 16, the plates being bent towards each other to form the circular poles 3 of the resonator, and their outer edges being clamped outside the tube to a silvered metal ring 17. Radial apertures are formed in this ring to receive tuning plungers and to form connections for input and output transmission lines 23, 23<1>, the inner members of which are extended to form adjustable coupling loops 24, 24'. When used as a protective device, high voltages on the input side cause a discharge at the poles 3 and thus damp the resonator and prevent damage to apparatus on the output side. The glow discharge may be excited by an external control applied to an electrode such as 25 placed axially in the tube 16 and terminating in an insulating tube close to the poles 3. To minimize time 'lag at the commencement of the discharge, a steady discharge may be passed between the outside of the resonator and one or more auxiliary electrodes within the tube, and ionization may be produced by a deposit of mesothorium or radium compounds on an auxiliary electrode or on the resonator surface near the poles ; or photo electrons may be produced by a luminous source shining into the tube. The tube filling may comprise water vapour at a pressure of 3 to 10 mm. of mercury, water vapour mixed with one or more gases such as hydrogen or helium, alcohol or other organic vapour, hydrochloric acid, or ammonia. When wave guides are used for the input or output energy, the guide opens directly into the resonator through a suitable aperture.

Title: Improvements relating to the manufacture of mixed oil gas and water gas
IPC: C10J1/213
Filed: 1930-01-29
Abstract: 335,495. Humphreys & Glasgow, Ltd., (Assignees of Terzian, H. G.). July 11, 1929, [Convention date]. Producers.-In the manufacture of mixed oil gas and water gas, in which oil gas is passed through an ignited fuel bed, the carbon deposited being consumed in the water gas reaction, steam is generated in the tar washer by the passage of hot oil gas and this steam is used in the generator to form water gas. The generator 1 is blasted with air to heat the fuel bed and the vessels 2 and 3, oil is then supplied by pipe 27 to vessel 2, steam or gas being admitted through pipe 28 and the oil gas passes by conduit 16 to a wash box 4 in which water vapour is formed. The mixture of oil gas and water vapour passes through a condenser 5 and by conduit 23 to the top or bottom of the fuel bed 8 when the oil gasis cracked depositing carbon which reacts with the steam to form water gas, the latter passing through conduit 32 to a wash box 6, condenser 7 and outlet 21. The amount of water gas generated may be controlled by controlling the amount of steam formed in the wash box 4, and this is done by governing a re-circulating pump 51 so that the temperature of the water as shown by a thermometer 53 is regulated, cold water being admitted as desired from an inlet 33. The water vapour may be further controlled by the admission of cooling water to the condenser 5, and this may be automatically governed by a thermostat 49 which operates a motor for setting the cold water inlet valve 38. Further control may be secured by bye-passing the gas round the condenser 5 through pipe 30.

Title: Improvements in or relating to friction clutches and brakes
IPC: B64C25/46
Filed: 1931-01-31
Abstract: 371,945. Brakes ; friction and freewheel clutches. PERKINS, F. A., Old Vicarage, Whitstable, and CHAPMAN, C. W., Waterford House, Rede Court, Strood, both in Kent..Jan. 31, 1931, No. 3173. [Class 103 (i).] In a brake or a friction clutch of the kind in which disengagement is facilitated by centrifugal force, a link supporting a friction shoe against a drum lies at an angle to the normal to the drum surface, the tangent of which is greater than the coefficient of friction of the surfaces but small enough to cause the shoe to wedge against the drum. The driven or stationary drum 10, Fig. 1, is engaged by one or more shoes 15, each connected to a control collar 19, slidable on the shaft 11, by a rigid or telescopic spring toggle link 20 and universal joints 21, 22, each shoe being further acted on by an inclined link 13 pivoted at 12 to a boss on the shaft and connected to a weight 18 to assist declutching by centrifugal force. The pivot 16 is offset from the centre of the shoe, and the link 13 is so inclined that, when the shaft 11 rotates counterclockwise and the links 20 are straightened, the shoe is tightened into engagement, but is released on clockwise motion. The shoe may be connected to the collar 19 by tension springs. Fig. 3 shows a modification in which bidirectional tightening is secured by two weighted arms 23, 24 either of telescopic spring form or, as shown, provided with slotted engagement 25 with their pivots 26. An aircraft landing-wheel brake, shown in Figs. 4 and 5, comprises a drum 29, fixed on the axle 28 and anchored by a strut 30 to the fuselage or wings, and shoes 15 connected to weighted levers 13, 14 pivoted at 12 on a flange 31 of the landing-wheel. The weights 18 are connected by tension springs 32 tending to apply the brake and are acted on by rotary cams 34 for locking the brake out of action. When the aircraft is stationary, a control collar 36 is withdrawn by a lever 37 and the brake is spring- applied, so obviating the use of chocks. When the pilot moves the lever 37 to the full-line position, Fig. 4, the cams 34 release the brakes. If, prior to landing, the lever 37 is again' moved to withdraw the collar 36, the cams 34 remain latched by steps 38 on the weights 18 until, on landing, rotation of the wheels causes outward movement of the weights to free the cams, which are then rotated by centrifugal weights 35, so that, as the wheels slow down, the springs 32 apply the shoes with progressively increasing pressure.

Abstract: 582,510. Control of A.C. motors; liquid controllers. SHEPHERD, G. R. (Westinghouse Electric International Co.). Feb. 22, 1944, No. 3251. [Class 38 (iii)] A control system for an induction motor M comprises two liquid rheostats of different crosssectional area and current-carrying capacity connected in series with the motor secondary winding so that the smaller rheostat 23 controls the motor within a low speed range and the larger 48 within a high speed range. When a "start" push-button is depressed a coil 14 is energized to operate a contactor 16 and connect the motor primary winding to the supply. To decrease the secondary resistance a "down" push-button is actuated to energize a motor M1 and lower an element 12 until a limit switch 24 is closed and a coil 26 is energized to move a contactor 27 which short-circuits the rheostat 23 and moves a contact 31. A motor M2'is thereby energized to lower an element 13 until a limit switch 37 is actuated, at which point the induction motor has reached full speed. To increase the secondary resistance the "up" push-button is depressed to energize the motor M2 and lift the element 13 until a switch 49 is moved to energize the motor M1 and lift the element 12 until contacts 45 and 46 are separated. If the contactor 16 drops, due to failure of voltage supply to the control circuits, a contact 47 will close to shunt the "up" push-button and place both rheostats fully into the secondary circuit.
