Title: Diaphragm valves
IPC: F16K7/12
Filed: 1934-10-10
Abstract: 442,790. Diaphragm valves. SAUNDERS INVENTIONS, Ltd., 98, Beresford House, P.O. Box 6508, Main Street, Johannesburg, South Africa, and SAUNDERS, P. K., 5, Tettenhall Road, Wolverhampton. Oct. 10, 1934, No. 28999. [Class 135] In a diaphragm valve device with a substantially straight-through bore and shallow transverse weir 2 with which the diaphragm co-operates, the diaphragm 4 has a turned-up margin by which it is clamped on three sides between flanges 6, 7 on the body and flange 8, 15 on a detachable cap 9. A straighter passage may thus be obtained by a lower mounting of the diaphragm and a lowering of the weir. The diaphragm side of the passage may also converge towards the diaphragm. One side 18 of the passage may be bulged and the other 17 made straight, so that when the device is arranged with the straight side underneath, trapping of material in the valve is obviated. The passage may be lined with rubber 25 which may be integral with the seating, being held in a dove-tail 26. The cap 9 may be held by wedges 13 passed through posts 11, 12 ; on removal of the wedges the cap may be swung about a hinge 14 at the bottom of post 11. The bore of the cap and flange 15 may be formed as a cylinder and the actuator 21 as a piston whose end fits the diaphragm when closed, and which in opening produces suction in space 22. The piston also prevents escape of fluid in the event of fracture of the diaphragm. Specifications 321,892, [Class 135], 362,084, 434,665, and 439,701 are referred to.
Patent GB-712689-A (GB)
Title: Process for producing combustible gas enriched with methane
IPC: C10J1/213
Filed: 1950-11-27
Abstract: In a process for enriching blue water gas (see Group XII) a gaseous mixture containing carbon monoxide and hydrogen, in a volumetric ratio of 1 : 3 is diffused from blue water-gas into a diluent gas in an apparatus comprising one or more porous diaphragms through which diffusion can occur.  As shown in Fig. 1 blue water-gas is fed though an inlet 2 of a diffusion apparatus 1 into a space 3 surrounding a tubular porous diaphragm 4 which may be made of metal gauze.  The diluent gas which may be steam or a mixture of methane and steam enters the diaphragm 4 in the direction shown and the velocities of the gases and the area and the permeability of the diaphragm are chosen so that the gaseous mixture leaving the apparatus to be catalytically reacted in a zone 7 contains carbon monoxide and hydrogen in the required ratio.  To prevent counter-diffusion in the apparatus 1, the pressure in the space 3 is maintained in excess of the pressure within the tubular diaphragm 4.  In a modified form of <PICT:0712689/III/1> apparatus the diffusion is carried out by causing the streams of blue water gas and diluent gas to travel through a tubular vessel in the same direction side by side in a condition of streamline flow so that diffusion takes place transversely of the direction of flow.
