Title: Improvements relating to the control of the mixing of liquids
Inventor: FAWCETT SYDNEY
IPC: B01F15/00
Filed: 1951-10-26
Abstract: 714,173. Imparting special properties to water. PERMUTIT CO., Ltd. Oct. 10, 1952 [Oct. 26, 1951], No. 25124/51. Class 46. [Also in Groups II, XXXV and XXXVI] Apparatus for determining the neutral point when mixing alkaline and acidic solutions for, e.g. a water supply, by determining the point of inflection in the conductivity curve comprises two conductivity cells located at different points along the resultant flow pipe, whereby simultaneous conductivity measurements indicate the change in conductivity and may be used to control the supply of alkaline or acidic solution to the mixture. The two cells A, B, Fig. 3, physically located in a branch pipe with A nearer the blending valve, are electrically connected to a rectifier bridge 13 so that when the conductivity of A is a predetermined amount greater than that of B a relay 14 operates, and energizes a two-step relay 15 to reverse a motor 26 controlling the input of alkaline and acidic solution to the mixture, so that the mixture hunts between a slightly acidic and slightly alkaline condition. Fig. 9 shows a circuit for controlling the constituents of a mixture in which neutrality produces a change in the conductivity curve but not a minimum. If the mixture is initially acidic with alkaline solution being added, winding 58 is energized to close contacts 54, energizing relay 55. Shortly after the water passes through neutrality the conductivity of cell A is sufficiently closer to that of B for contacts 54 to open and relay 55 falls. Shortly after that the conductivity of A is nearer still to that of B. and contacts 53 close, energizing relay 56 followed by two-step relay 52, thereby reversing the motor 26 to add acid to the water and also energizing relay 51, which completes its holding circuit, and inserts resistance 50 in series with cell A. Thus the conductivity of the arm containing cell A is again reduced and contacts 53 re-open, though contacts 54 do not close and relay 56 falls, followed by relay 52. When the water passes through neutrality in the opposite direction, the conductivity of A rises sufficiently to close contacts 53. Relay 56 again energizes to reverse the motor 26. Subsequently contacts 54 will close, resistance 50 is short-circuited, and the cycle recommences. In another embodiment only one cell is used, the conductivity being measured in a bridge circuit, wherein a variable resistance is controlled to be equal to that of the cell by a motor, rotating in one direction with increasing conductivity and vice versa. Attached to the motor shaft 30, Fig. 6, is a disc 31 having a pin 32 that strikes against weighted lever 33, so that a change in the direction of rotation causes lever 33 to rock a second lever 35 to close or open contacts 38-40, whereby the valve blending motor is reversed. Facilities are provided for ensuring a reversal after a given maximum time interval.

Filed: 1946-08-23
Abstract: 637,230. Television. BRADY, J. B. Aug. 23, 1946, No. 25216. Convention date, Sept. 5, 1945. [Class 40 (iii)] A television transmission system by which may be transmitted at will either scenes or printing telegraph messages comprises an automatic printing telegraph transmitter controlling a receiver to produce messages on a transparent web, means for projecting an image of the web on a light-sensitive mosaic connected with a transmission channel, and progressively adjustable means for conditioning said channel for transmission prior to the starting of said transmitter and operative at the end of the progressive adjustment to start said transmitter. A printing-telegraph receiver 30 receives signals from an automatic transmitter 45 or manual transmitter 44 via a switch 41 and records the message in page form on a wide transparent tape 34. The message is optically projected, while it is being printed, on to an iconoscope 26 whose output may be amplified at 25 and transmitted over a transmission channel 3, 4 to energize a distant television receiver. A similar iconoscope 10 may transmit a scene 14 via an amplifier 15. Only one iconoscope transmits at a time, a rheostat arm 19 being manually rotated so that one or other of the amplifiers 15, 25 is biassed to cut-off and the other is biassed operatively. When the arm 19 is in the broken line position 23 to block the valve 15 and iconoscope 10 an abutment 55 closes contacts 51a, 52a, energizing a solenoid 50 to close contacts 48 and start the automatic transmitter 45. A tape printer 40 is used to monitor the message reproduced on the tape 34, since the optical projector system and iconoscope 26 are-enclosed in a cabinet and the tape 34 is therefore not visible.

Title: Improvements in the manufacture and production of motor fuels of low boiling point
IPC: C10G45/00
Filed: 1936-09-18
Abstract: Motor fuels are produced by passing aliphatic hydrocarbons containing up to 5 carbon atoms and mainly of a saturated nature, or mixtures containing them, together with hydrogen under a total pressure of at least 100 atmos., and a partial pressure of the said hydrocarbons of at least 65 per cent of the total, at a temperature above 450 DEG  C. over catalysts having a strong hydrogenating or an acid and a splitting action.  The partial pressure of the hydrocarbon is preferably 65-75 per cent for pentane, 70-85 for butane, 80-90 for propane, and 90 up to nearly 100 per cent for ethane.  The total pressure is usually 100-600 atmos., and temperature is 450-700 DEG C.  Hydrogenating catalysts include sulphides of Mg, Al or heavy metals, and particularly of Groups 5 and 6, and the metals of these groups or their compounds.  Catalysts having an acid and splitting action are metals or their compounds, together with halogens, halides of hydrogen or metalloids, or phosphoric acid, or halides of metalloids alone, preferably on carriers.  Mixtures of aluminium hydroxide, ammonium molybdate, and active carbon; of vanadium and tungsten oxides or sulphides; of zinc and magnesium oxides and molybdic acid in sulphurized form; copper or zinc silicate with tungsten or molybdenum sulphide; or a sulphurized tin, boron, tungsten mixture are particularly suitable.  Usually conditions are chosen so that only 10-60 per cent of the hydrocarbons are reacted. Hydrogen must still be present after reaction.  That dissolved in the compressed liquefied hydrocarbon is generally sufficient.  The reaction product yields the desired liquid fuels together with unreacted initial hydrocarbons and corresponding olefines which are recycled.  In an example, a mixture of 80 per cent n-butane and 20 per cent hydrogen is led at 300 atmos. and 530 DEG  C. over a mixture of tungsten and nickel sulphides.  The liquid products comprise benzene of octane value 82 and a middle oil.  Methane, propane and ethane are also formed.
