Abstract: 502,811. Flowmeters. NUTSFORD, A. Sept. 24, 1937, No. 25906. [Class 69 (i)] A flowmeter comprises a knife-edge orifice through which the fluid flows with turbulence and a resilient pressure responsive member of thin metal or like resilient material which is connected to the indicating element and which separates the high and low pressure sides of the instrument so that it is responsive to fluctuations in the pressure drop across the orifice. In the instrument shown the orifice 7 is formed in a flexible diaphragm 6 forming a wall of a capsule and constituting the pressureresponsive member, the fluid entering at 8 and, after passing the orifice 7, leaving at 9. Correction for variations in density may be provided by a float 19 which raises and lowers a pivoted arm 21 through which the diaphragm operates a lever 23 forming part of the indicatoroperating mechanism, thus altering the point of contact of the arm and lever and hence the effective transmission ratio of the mechanism.' The whole of the moving parts may be housed in the casing, the indicator being read through a transparent wall,'or the indicator may be outside the wall and operated through it by magnetic means. In a modification the pressuredrop orifice is provided in a removable plate secured over an opening in the rigid wall of the capsule, so that an orifice of suitable size may be used in a standard instrument.

IPC: H01C10/26
Abstract: 261,191. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Nov. 24, 1925. Variable resistances: wireless tuning-apparatus, adjustment devices for.-In resistance control devices for radio and other apparatus of the type in which a resistance element mounted on the circumferential periphery of a drum and a contactor sliding over the resistance are relatively rotatable about the axis of the drum, the resistance element is retained against lateral movement in one direction by friction between it and the drum. Resistance wire 29<a>, Figs. 3 and 4, may be wound around a flexible insulating strip 31<a> which is removably held around the supporting drum 21 against an annular shoulder 30, the ends of the strip 31a being drawn together by engagement with the ends of a resilient, U- shaped, metal link 37 the middle of which extends into a recess 36 in the drum 21. Lateral movement of the strip off the drum is thus prevented by friction between the strip and the drum and circumferential movement by the engagement of the link 37 in a recess 36. The ends of the wire 29a may be threaded through openings in the ends of the strip 31<a>. The drum 21 may be rotatably mounted on a hub 10 and a stationary contact 72 may be carried by an extension 56 of a metal bracket 13- rigidly secured to the hub by spinning over the end of the hub. An element 1'7 with a tapered part 20 is screwed interiorly into the hub 10 to grip the bracket 13 against a panel 18 as, shown in Fig. 3. Rotation of the drum is limited by a projection 27 on the bracket 13 engaging a groove in the drum. A shaft 48 extending through the hub 10 carries at its outer end a knob 54 and pointer 55 acting as lock nuts and at its inner end is resiliently and operatively connected to the drum 21 by a resilient metal plate 43 rigidly secured to the shaft 48 by riveting over the end of the shaft and soldering. The plate 43 has radial projections 42 engaging recesses 41 in the drum 21 and urges the shaft 48 inwardly, a shoulder on the shaft 48 engaging an interior shoulder 50 on the hub 10 to give good electric contact between the hub and shaft. The contact 72 has a raised rib 73 and is connected to a terminal 71 and insulated from the part 56. One end of the wire 29<a> is connected to the end of the shaft 48 and so through the parts 10, 13, 56 to a terminal 66. In a potentiometer, the other end of the wire 29<a> is connected to a metal ring 74 on the drum co-operating with an arc-shaped contact 78 carried by, but insulated from, the part 56. In a radio rheostat, the parts 74, 78 are omitted and one end of the strip 31<a> is unwound so that the circuit may be broken at this position of the drum 21, a projection on the strip 31a raising the contact 72. The value of the resistance of the wire 29a is marked on the strip 31a.

Title: Improvements in or relating to the moulding of plastic substances
IPC: B28B13/02
Filed: 1931-09-18
Abstract: 379,871. Moulding bricks s & c . PROCTER, J., 93, Halifax Road, Nelson, Lancashire. Sept. 18, 1931, No. 26131. [Class 87 (ii).] Moulds are filled with plastic material which has been preformed into pellets or balls to lessen the power required for the consolidation. As shown, the material, i.e. ground shale or dried clay, is fed from a hopper 1 to a mixer 2 to which water is supplied. The mixing is effected by rotary knives which propel the material to the exit 3 from whence it falls into the bight between a pair of inclined hollow perforated drums 4, which revolve in opposite directions. The material is thus forced through the perforations into the drums, forming short bars or cylinders which become rounded by tumbling towards the exit ends of the drums 4. The balls or pellets fall on to an inclined shoot 7 which directs them into the stationary hopper 8 of a brick-forming machine. The moving carriage 10 receives the balls and deposits them in a mould 11 to be pressed by a piston 12 operated by a crosshead 13. To prevent the balls from sticking on the shoot 7, the floor thereof has longitudinal sections 17 hinged at their upper ends and vibrated by linkage 21, 22, 24 actuated by a projection 20 on the link 21 engaging a projection or projections 19 on the crosshead 13. The amplitude of the vibration is varied by an adjusting nut 26. The shoot 7 is covered by a canvas or fabric cloth and may be heated by steam pipes to prevent adhesion of the balls. A battery of moulding machines may be fed from a single pair of perforated rolls, the pelleted material being discharged on to an endless conveyer running perpendicularly to a number of inclined shoots each leading to the hopper of a moulding machine.

Abstract: 889,639. Preparing phosphine electrolytically. ALBRIGHT & WILSON (MFG.) Ltd. July 26, 1960 [July 31, 1959], No. 26293/59. Class 41. Phosphine is made by passing an electric current through an aqueous electrolyte e.g. H3PO4 or H2SO4, using as cathode a metal having a hydrogen over-voltage, preferably mercury, in contact with white phosphorus preferably in molten state. The electrolyte is agitated to make contact with the cathode which may be Hg, Zn, Fe, Ni, Co, Ag, Cu, Cd, Al, Bi or Sn. Alternatively if an inert metal cathode is used, a metal salt e.g. PbSo4 is added to the electrolyte and the metal plated out on the cathode. A suitable apparatus consists of a glass vessel 10, Fig. 1, mercury cathode 11 with a supernatant layer of molten white phosphorus 13 which is agitated by a stirrer 15 to bring the mercury in contact with the aqueous electrolyte 14. Anode 17 is mounted in a glass tube 18 having a sintered glass separator 20, thus preventing phosphine from entering the anode compartment, where oxygen may be generated when a metal anode is used. A carbon anode generates Co2 when a separator is not essential. A solid metal cathode may be used, which projects through the aqueous electrolyte into the molten phosphorus which creeps up the outer surface of the electrode. As electrolyte, mineral acids, strong organic acids, or a salt e.g. alkali metal salt is specified for example phosphoric acid, containing a small amount of lead acetate or barium chloride. In examples, lead, an alloy of Ni, Cu, Cr and Fe, used as cathodes and lead peroxide, platinum, or an alloy of Sn and Bi as anode. U.S.A. Specification 1,375,819 is referred to.
