Title: Improvements relating to the treatment of concrete
IPC: C04B40/02
Filed: 1935-12-13
Abstract: 458,708. Drying concrete. BILLNER, K. P., 30, Rockefeller Plaza, New York, U.S.A. Dec. 13, 1935, No. 34602. Convention date, Oct. 5. [Class 34 (ii)] [See also Group V] Laid or formed concrete in plastic condition is subjected, in order to harden it, to suction behind a movable element while excluding air from between the element and the concrete. On the surface of the concrete in a mould 1 is placed a screen 3 of fine wire or canvas and on this a flexible cover 4 of rubber &c. The undersurface of the cover 4 is provided with grooves or channels which communicate with pipes 7 leading to a suction pump 13. The edges of the cover 4 are sealed by weighted flaps 15. In a modification, a rigid metal cover may be used which may be curved when forming roads &c. The action of the suction removes water from the concrete and also causes a heavy atmospheric pressure to be exerted on the cover 4, thus compressing the concrete. For operating continuously, a number of covers may be used end to end, a cover being moved from one end to the other as the concrete is laid. Instead of providing sealing flaps, the screen 3 may be reduced in size so that the cover 4 contacts with the concrete round the edges and acts as a seal.

Title: Improvements in and relating to nuclear reactors
Inventor: UNDERWOOD ROBIN ARTHUR
IPC: G21C17/10
Filed: 1960-10-10
Abstract: 922,572. Nuclear reactors. C. A. PARSONS & CO. Ltd. Sept. 29, 1961 [Oct. 10, 1960], No. 34663/60. Class 39 (4). A nuclear reactor having thermocouple arrangements for measuring temperatures wherein the thermocouple cables pass from a fuel channel through a plug sealing a standpipe passing through a reactor shield and pressure vessel is characterized in that the cables are connected together so as to form in effect a flexible flat belt. In Fig. 1 some or all of the fuel elements in a fuel channel are provided with thermocouples, the cables 4 of which pass up the side of the channel to a contact box 5 located at the top of the channel. The box 5 is in two parts which are separable by the application of a lifting force. The thermocouple cables emanating from the box 5 pass through a charge fan 6 and a guide tube 7 supported on the lower side of a plug 8 which seals a standpipe 9 passing through the reactor shield and pressure vessel (not shown). The cables pass through the plug and over a pulley 11 to an anchorage 12. The pulley may be mounted on a support 13 which rests in a recess in the plug to allow the pulley to be raised some distance before the lifting is applied to the plug; this allows the upper part of box 5 to be drawn clear of the fuel channel and into the guide tube 7 before the plug 8 is lifted. The cables, at least in the part which passes over the pulley and preferably from where they leave the box 5, are interconnected either by a wire interwoven with the cables, Fig. 3 (not shown), or by being interwoven themselves, Fig. 4 (not shown). This relieves strain on the cables during charging and discharging and reduces the chance of the cables becoming entangled; if a cable is broken it is held in position and is not likely to obstruct the fuel channel.

Title: Improvements in or relating to apparatus for measuring vapour pressure
Inventor: SUMNER FRED
IPC: G01N7/14
Filed: 1954-12-07
Abstract: 768,744. Measuring vapour - pressures. SHELL. RESEARCH, Ltd. Dec. 7, 1955 Dec. 7, 1954], No. 35458/54. Class 106 (2). A method of continuously measuring and/or recording the vapour pressure of a stream of liquid comprises causing a stream of gas saturated with vapour from the liquid held at a reference temperature to flow through a conduit or orifice and continuously measuring or recording the pressure drop. Gasoline to be tested is pumped by a pump 6 through a filter 1 and conduit 5 via a heating coil 3 to a column 2, in which a constant liquid level is maintained by an electrode 9 and a capacity-sensitive proximity switch 4 operating a valve 8, and thence via conduit 7 and valve 8. Air is pumped through a filter 10, drier 11; heater 12, conduit 13 and valve 15 into the column 2, the flow being regulated to a constant molecular flow rate, preferably four times by volume the liquid flow rate, by an air pressure regulator 17 and flow controller 18, the reference pressure for the regulator 17 being obtained from a constant pressure chamber 21. The enclosure 14 is a constant temperature enclosure. The air entering the column 2 is dispersed by a sintered stainless steel disc 16 and the height of the column is such that the air becomes saturated with gasoline vapour. The saturated air passes through a valve 19 to a restrictor 20, preferably a deformable Bourdon gauge capillary whose radius may be increased or decreased to vary its flow resistance, and thence to the constant pressure chamber 21 and to the atmosphere at 22. The pressure drop across the restrictor 20 is applied to a differential pressure recorder through conduits 25, 26 and valves 33, 34, a pressure transmitter 23 being provided in the high-pressure limb. The resistance of the restrictor 20 may be periodically checked by applying air pressure directly thereto through valve 27 and conduit 28. The reading range of the recorder 24 may be adjusted by a connection 24a including restrictors 35, 36 and valve 37 enabling a biasing pressure to be applied to the lowpressure limb of the recorder. The pressure drop across the disc 16 may be tested by opening valves 31, 32 and closing valves 33, 34.

Filed: 1928-12-03
Abstract: 301,750. Naamlooze Vennootschap Nederlandsche Naamlooze Vennootschap Fransch - Hollandsche Oliefabrieken Nouveaux Etablissements Calve-Delft. Dec. 3, 1927, [Convention date]. Food fats. - For producing or improving the aroma of edible fats, such as margarine, artificial cream, &c., diketones, such as diacetyl, or substances capable of being transformed into diketones are added during manufacture under such conditions that the quantity of diketone in the product does not exceed about 4 parts per million. Diketones or reduction products thereof in milk or other aqueous liquid may be mixed intimately with the fats and oils so that the diketones are transferred thereto, the liquid being subsequently separated from the mass. Several examples are given of which the following is one: 90 kilos of Premier Jus, 90 kilos of cocoanut oil, 300 kilos of palm kernel oil and 120 kilos of ground nut oil are brought to a temperature of 39‹ C. and intimately mixed; after the gradual addition of 150 litres of water and 50 kilos of broken ice the mass is churned to a homogeneous product and 3 grams of methylacetylcarbinol are then added, whereupon the emulsion is passed over a cooling drum and exposed for a sufficient time to the air to effect the oxidation to diacetyl. Perchlorates, organic and inorganic peroxides, quinones &c. may be used as oxidizing agents. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use as oxidizing agents of substances having an indirect action such as acetaldehyde, and states also that radiation with light rays of short wave length either alone or together with an oxidizing agent may serve the purpose. This subject-matter does not appear in the Specification as accepted.

Title: Automatic tuning apparatus for a television receiver
IPC: H04N5/50
Filed: 1959-10-21
Abstract: 874,287. Television. HAZELTINE CORPORATION. Oct. 21, 1959 [Nov. 18, 1958], No. 35677/59. Drawings to Specification. Class 40(3) In a monochrome or colour television receiver intended for the reception of either monochrome or compatible subcarrier-type colour signals, the preferred tuning relationship established by most uses for monochrome reception is such as to cause the sound carrier and subcarrier of a colour signal, if one is subsequently received, to be positioned relatively high up the slope of the I.F. response curve with the consequent production of a difference frequency beat pattern. In accordance with the invention, a detector gated by the line flyback pulses is employed to sense the presence or absence of a subcarrier synchronizing burst and to control a reactance circuit to shift the receiver tuning by changing the frequency of the mixer oscillator. By this means the receiver is automatically shifted from the preferred to a correct tuning relationship when the received signal changes from monochrome and colour and is shifted from the correct to the preferred tuning relationship when the received signal changes from colour to monochrome. In a colour receiver the gated detector may comprise the normal colour burst detector. The reactance circuit may comprise a reactance valve stage or a fixed inductor which is switched into and out of circuit by a diode switch.
