Inventor: ADAMS FREDERICK DOUGLAS
IPC: F16K1/20
Filed: 1954-03-12
Abstract: 762,598. Pneumatic conveyers. LODGECOTTRELL, Ltd. April 28, 1955 [March 12, 1954], No. 7337/54. Class 78 (1). A flap valve for use in an air-lock hopper comprises a flap 3 and a counterweighted lever arm 8 mounted on a shaft 4 so as to have limited relative rotation, the arrangement being such that the flap opens under the action of gravity when the weight 11 is raised and closes when the weight is lowered. The flap 3 is mounted on a shaft 4 which has an enlargement 5 formed with a pair of flats 6. These flats co-operate with a similar pair of flats 10 formed on the raised part 9 of a boss 8a which is formed on the lever 8 and is rotatable on the shaft 4. The enlargement 5 may be a boss which is keyed to the shaft 4 and is formed on a counterweighted lever 7. Each lever 8 has an arm 14 which carries a roller 13. These rollers are in the path of a cam 12 carried on a power-driven shaft 19.

Title: Improvements in or relating to the construction of pistons for internal combustion engines, compressors and other similar machines
IPC: F16J1/00
Filed: 1959-03-03
Abstract: Bearing bands of anti-friction metal are formed on the skirt of a piston by spraying the metal on the piston in the form of molten particles and then subjecting the anti-friction metal coating to heat treatment in the presence of a reducing agent, preferably hydrogen, to reduce oxides of the metal and to weld the particles together.  In the example given, the relevant parts of the skirt are roughened and the particles of molten metal are sprayed thereon by compressed air from a spray gun, the resulting coating then being heat treated at a temperature of between 600 and 800 DEG C. The anti-friction metal may be copper, tin, lead, antimony or an alloy of one of those metals and the piston may be of iron or steel.

Title: Processes for the Preparation of Iron Salts of Carboxyl Group-Containing Polymers.
IPC: A61K33/26
Filed: 1966-06-08
Abstract: 1,155,209. Preparation of polymeric ferrous salts. TEIKOKU HORMONE MFG. CO. Ltd. 8 June, 1966 [8 June, 1965; 17 Nov., 1965; 18 Nov., 1965], No. 7453/69. Divided out of 1,155,208. Heading C3P. Ferrous salts of water-soluble carboxyl groupcontaining polymers are prepared by mixing a water-soluble inorganic ferrous salt with a said water-soluble polymer, or an alkali metal, ammonium or amine salt thereof, in an aqueous reaction medium and, if the pH of the reaction medium is below 6, adding alkali to the solution to bring the pH to at least 6; and recovering the solid ferrous salt of the polymer thus obtained. In a modification, the reaction medium is maintained at a pH below 6 and the polymer solution is contacted with an anion-exchange resin whereupon, after separating the solution from the resin, the ferrous polymer salt is recovered by either evaporating the solution under reduced pressure or adding a water-miscible organic solvent, e.g. alcohol or acetone, to precipitate the polymer salt. The ferrous salt used may be the sulphate, chloride, bromide or nitrate, or ferrous alum or Mohr's salt (ferrous ammonium sulphate). The starting polymer is preferably a homopolymer or copolymer of an ethylenically unsaturated carboxylic acid, e.g. acrylic, methacrylic or maleic acid. Suitable comonomers for the acids include styrene, vinyl acetate, vinyl alkyl (C 1 -C 4 ) ethers, alkyl (C 1 -C 4 ) acrylates and alkyl (C 1 -C 4 ) methacrylates. In some examples, a vinyl methyl ether-or vinyl acetate-maleic anhydride copolymer is used as starting polymer, the anhydride groups thereof being hydrolysed to free acid groups in situ in the aqueous reaction medium; and in one Example (No. XVI) the ferrous salt of such vinyl methyl ether-maleic acid copolymer is blended, while in an aqueous medium, with microcrystalline cellulose.

Abstract: 100,688. Santamaria, A. S. de. June 15, 1915, [Convention date]. Tension apparatus.-An apparatus for setting fractured limbs comprises a pair of curved metal plates c which are secured by plastered gauze to the limb on each side of the fracture. The spherical ends b of rods a secured to the plates, are then inserted loosely in split clamps f by screwing up butterfly-nuts h. The oppositely-threaded screw apparatus d, e is manipulated to separate the plates until the fractured ends of the bone no longer overlap. Either end of the appliance can then be moved laterally about the remote ball b as a pivot until the two parts of the bone are in alinement, whereupon the nuts h are screwed up tightly to lock the whole appliance, so that it acts similarly to a rigid splint, in which position it remains until the fracture is healed. Usually, two such appliances would be used, one on either side of the limb.

In a multiplex or frequency shift signalling, e.g. teleprinter system, in which characters are represented by tones, a synchronizing tone burst, e.g. 6 cycles, is inserted in the signal at intervals equal to an even number n, e.g. 64 cycles of the synchronizing tone and used for synchronizing a coherent (phase locked) oscillator 1 in the receiver, e.g. a tuning fork oscillator of frequency 384 c/s. The oscillator output (limited to rectangular waveform) is n periodically phase reversed every - (e.g. 32) 2 cycles of the tone and applied to a phase detector 7 together with the synchronizing tone, e.g. 384 c/s., separated from the received input by an attenuator (sync. gate) 2 with gated output only during a sync. burst gating interval of <SP>1</SP>/ 32  sec. controlled from a counter 5 operated from pulses received from the oscillator 1, so that at correct synchronism the phase reversal occurs mid-way of each synchronizing tone burst and the phase detector average output is zero. Incorrect timing of counter circuit 5 however produces an average output from phase detector 7 which is periodically sampled (connected to earth through an output circuit) by a relay 9 to produce pulses of one or other polarity which are respectively amplified by one of amplifiers 10, 11 and applied to operate a gate 4 whereby a timing pulse from the oscillator to the counter 5 is blocked or an additional single pulse added intermediately between the drive pulses from the oscillator. The timing counter circuit 5 is therefore adjusted until the output of phase detector 7 is zero. To allow for slight hunting about the correct timing the attenuation of attenuator 2 is rendered zero during a period centred over twice the synchronizing tone duration.
