Title: Automatic fluid flow control devices
IPC: F16K31/48
Filed: 1975-02-26
Abstract: 1461369 Valves E A EDWARDS-ROUX 26 Feb 1975 8100/75 Heading F2V A clockwork controlled valve 3 between inlet and outlet connections 1, 2 is actuated by a diaphragm 8 via lever and rods 5, 4, 7, the the diaphragm being deflected against a spring 10 by pressure from the inlet via passages 12, 19 and valve 18 which is opened by an extension 17 of a connecting rod 14 acted on intermittently by an arm 15 of the clockwork. When the arm 15 releases rod 14, pressure on a piston 13 moves extension 17 away from valve 18 which closes, and fluid escapes from the diaphragm chamber via outlet 16 . Energy for the clockwork is transmitted by a similar mechanism, Fig. 2 (not shown), in which a ratchet (26) is actuated from a diaphragm (23) via levers to wind a spring. A gear (32) also operated from the diaphragm reciprocating a rod (29) to actuate the valve (33). The two mechanisms may be assembled as shown in Fig. 3 with diaphragms 8, 23 in chambers 9 and 20 deformable by pressurized fluid via passages 12 and 22 respectively. Valves 18, 33 are formed as flaps by slits (42), Fig. 4 (not shown). An additional valve (36) of similar form is provided as a check valve in the discharge line (35).

Title: Improvements in and relating to carburettors
IPC: F02M1/00
Filed: 1931-03-17
Abstract: 362,802. Lubricating. DOBBIE, E. D., Balvonie, Skelmorlie, Ayrshire. March 17, 1931, No. 8139. [Class 12 (iii).] In a carburetter in which the fuel supply is controlled by the pressure of the lubricating oil system, lubricating oil is added to the fuel as a consequence of the lowering of the pressure of the oil supply. The pressure of the oil acts through a diaphragm 11 and a piston 8 to control a spring-loaded valve 6 in a fuel supply conduit leading to the carburetter. A pin 15 is provided to hold open the valve 6 when no oil pressure is available. The. diaphragm 11 is secured between a ledge 12 and a ring 13 on a cylinder 1 and may be secured to the piston 8 at its centre. A spring- loaded non-return valve 22 in a byepass allows a small quantity of lubricating oil to pass through a passage 21 to an annulus 25 ; when the valve 6 closes the oil escapes along the stem of the valve to a port 5 and is carried into the carburetter by the liquid fuel when the valve 6 is opened.

Title: Process for the manufacture of potassium manganate
IPC: C01G45/12
Filed: 1928-03-19
Abstract: 292,991. Soc. Chimique des Usines du Rh¶ne. June 29, 1927, [Convention date]. Potassium manganate is manufactured by suspending manganese dioxide in an excess of melted caustic potash containing water, containing 60-85 per cent of potassium hydroxide, and heated to a temperature of approximately 160- 200‹ C., and blowing pure or dilute oxygen through the mass, which is also mechanically stirred. The rate of flow of the gas is adjusted to carry away the greater portion of the water liberated during the reaction. At the end of the reaction, the excess alkali may be recovered by treating the reaction product with a limited quantity of water or dilute alkaline lye or by decanting the fused mass. As raw materials, natural or artificial manganese dioxide may be used. Also, other oxides of manganese or compounds adapted to liberate them, which, under the conditions of the reaction, are transformed into manganate, may be used.

Title: Improvements in and relating to catalysts
IPC: B01J37/03
Filed: 1956-03-20
Abstract: Alumina based catalysts are prepared by treating aluminium amalgam at 80 DEG  C. or more with an aqueous solution containing one or more active catalyst components or compounds forming them on calcination and separating impregnated alumina hydrate which is then calcined. The impregnating catalysts may be metals or metal compounds from Groups VI or VIII of the Periodic Classification Table, for example, cobalt oxide and/or molybdenum oxide or compounds which will give rise to the active catalyts on calcining.  In the example given high-purity aluminium is immersed in 0.1 N hydrochloric acid for 3 hours followed by the addition of mercury and the mixture is allowed to stand for 1 hour.  The aluminium amalgam after removal of the excess mercury and hydrochloric acid is then rinsed and reacted at 95 DEG  C. for 16 hours with aqueous ammoniacal cobalt molybdate.  The impregnated alumina hydrate is removed by filtration, dried at 80 DEG C. for 24 hours and calcined at 550 DEG  C. for 2 hours to give an alumina based catalyst with a large surface area and average pore size of 72   units.  Specifications 815,513 and 815,514 are referred to.
