Abstract: 802,382. Flexible diaphragms. RADIATION, Ltd. April 16, 1957 [April 18, 1956], No. 11816/56. Class 122 (1). [Also in Group XXIX] The flexible diaphragm of a double-acting dry gas meter (Group XXIX) is preformed so as to produce on one side of a marginal portion a ridge i which is of sufficient height in relation to its width and the stroke of the diaphragm that it is maintained on the same side of the diaphragm in both directions of the diaphragm stroke. The diaphragm, which is of supple leather, is clamped at its outer edge between rigid cups f, f thereby forming the enclosing chamber into two separate parts g, h. The central part of the diaphragm is clamped between flanged discs b, b<SP>1</SP>.

Title: Production of hydrocyanic acid
IPC: C01C3/02
Filed: 1952-05-13
Abstract: In the production of hydrogen cyanide by the catalytic oxidation of a mixture of gaseous hydrocarbons and ammonia, the resulting gaseous mixture containing unreacted ammonia and hydrogen cyanide is contacted with an aqueous monoammonium phosphate solution to remove ammonia therefrom, the resulting solution of diammonium phosphate containing a part of the hydrogen cyanide in solution heated to liberate ammonia therefrom and the gaseous mixture of ammonia and hydrogen cyanide thus obtained contacted with a solution of caustic alkali to produce a gaseous ammonia substantially free from hydrogen cyanide.  The alkali cyanide so produced may be used to give further quantities of hydrogen cyanide by acidification.  Preferably the water vapour pressure of the solution of caustic alkali should be substantially the same as the partial pressure of water vapour in the gaseous mixture of ammonia and hydrogen cyanide, and the concentration of the caustic alkali should not be greater than 70 per cent.

Title: Improvements in and relating to apparatus for raising or forcing oils, spirits or other liquids
IPC: G07F13/02
Filed: 1928-11-22
Abstract: 325,601. Bywater, D. Nov. 22, 1928. Divided on 320,415. Direct liquidpressure apparatus. -Apparatus for delivering measured quantities of oils, spirits, &c. comprises a float &c. l having screw-threaded connection with a spindle p which is adapted to be rotated through bevel gears q, q<1> by a spindle r when the latter is released by the insertion of a coin &c. The movement of the float displaces a volume of a propelling liquid from the chamber b through a pipe c into an outer chamber a containing the oil &c., which is delivered through a valve a<4> and nozzle a<2>. The spindle r has a one-way clutch so that, when it is returned to its initial position, the float remains in the position to which it has been moved. A cam face r<4> on the spindle r permits a slight upward movement of the spindle p and float to prevent drip at the nozzle a<2>. The valve a<4> is opened by an eccentric r<3> on the spindle r and a rod a<5>. The propelling liquid may be omitted, the float then acting directly on the oil &c. Valves of the kind described in Specification 124,055 may be embodied in the apparatus.

A device for feeding stacks 1, 3 and 1, 4 of books or the like to the cutting station of an automatic three-cutter machine by means of a conveyer belt 2 comprises a feed stop 3 and a feed carriage 6 with a gripping device 7 and an engaging member 8, actuated once for each revolution of the driving shaft of the machine. The carriage is actuated by means of crank 10, lever 11 and tie-rod 12 and the device 7 by means of cam disc 13, spring-influenced cam roller 14, lever 15, tie-rod 16, connecting rod 17, levers 18, rail 19 and a ram 20 having a roller 21. Transfer by the device 7 takes place only when a limit switch a connected to stop 3 is depressed by a stack. When the switch is not depressed, a magnet b is energized to cause cam roller 14, carried by one end d of a pivotally-mounted lever c secured to lever 15, to swing down and away from cam disc 13 and lever 15 is then supported against a stop so that the carriage 6 has an idle stroke.

Title: Improvements in or relating to television and like transmitter apparatus
IPC: H04N5/228
Filed: 1937-04-28
Abstract: 475,473. Television transmitters. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. April 28, 1937, No. 12172. Convention date, April 28, 1936. [Classes 39 (i) and 40 (iii)] Each of a plurality of independently adjustable means 14 ... 17 is associated with a different region of the screen scanned in an iconoscope or the like and produces a signal which compensates in that region an interfering signal equivalent to a distribution of brightness superimposed on the image. The electrodes 14 ... 17 are in a plane in a separate cathode-ray tube 10 and have their potentials individually adjusted on a potentiometer 30. The electrodes emit secondary electrons when struck by the cathode ray, which has a substantial cross-section and moves in synchronism with that in the scanning tube so that each electrode is scanned while the corresponding area of the picture is being scanned. The secondary emission is collected by an electrode 31 in whose circuit is an impedance 32 from which the compensating signals are taken. The individual tappings on the potentiometer are adjusted by moving controlling-handles, which are distributed over a surface correspondingly with the associated regions of the subject, Fig. 4 (not shown).
Patent GB-798948-A (GB)
Title: System for reproducing signals from a magnetic medium
IPC: H04N5/92
Filed: 1955-04-27
Abstract: 798,948. Colour television. RADIO CORPORATION OF AMERICA. April 27, 1955 [May 3, 1954; May 20, 1954], No. 12214/55. Class 40 (3). Television signals including a 0-3 Mc/s. luminance signal from a source 11 and a 3.6 Mc/s. modulated colour sub-carrier from source 18 are recorded on tracks 14 and 15 of a magnetic tape 17 whilst a 2.4 Mc/s. pilot signal is added on a third track 16 and serves during reproduction to eliminate from the sub-carrier components frequency variations imparted by longitudinal speed variations in the tape motion. Before recording the sub-carrier components are reduced to a band of 2-3 Mc/s. by heterodyning in modulator stage 36 with a 6 Mc/s. signal derived by converter 39 from a 3.6 Me/s. source 38, the difference frequency components being selected by filter 37. The pilot tone is derived by a further modulator 140 as the difference between the 6 Mc/s. from converter 39 and the 3.6 Mc/s. from source 38. Signals reproduced from the tape tracks are obtained through amplifiers 27, 28, 29, the luminance signal being used directly whilst the sub-carrier components are restored to their original frequencies by heterodyning in modulator 132 with a 6 Mc/s. signal and selecting the difference frequencies by filter 134. The 6 Mc/s. signal is derived by the addition in modulator 130 of a 3.6 Mc/s. wave from source 133 with the 2.4 Mc/s. pilot signal. Since the pilot carries frequency variations imparted by the tape, the resulting 6 Mc/s. varies likewise and compensates for the corresponding variation imparted to the sub-carrier components. Figs. 1-3 (not shown) illustrate minor variations in the way in which the pilot signal is derived and the sub-carrier components are restored in reproduction. Fig. 5 (not shown) illustrates a modification in which the pilot signal is reduced to 0.8 Mc/s. and recorded on the same track as the sub-carrier components.
