Title: Improvements in or relating to an aerosol generator
IPC: B01F3/04
Filed: 1952-04-24
Abstract: 714,885. Spray-producers &c. TENNEY, W. L. April 24, 1952 [April 27, 1931], No. 10317/52. Class 69 (3)  An aerosol generator comprises a casing which houses a resonant intermittent combustion engine and its exhaust tube, into which tube a formulation is introduced for discharge from the outlet thereof, and for deflected flow through the interior of the casing in heat transferring relation with the engine before discharge from the casing. A heat and sound insulated chamber 22 is mounted on a framework 11 and houses two resonant intermittent combustion engines comprising combustion chambers 42, Fig. 5, inlet valves 43 and fuel lines 41. The inlet ends of the engines are contained in a further chamber 34 provided at the front of chamber 22, the chamber 34 being closed by a hinged door 37. Each engine has a curved exhaust tube 45 which is fed with atomizing liquid through pipes 136, 137 and which leads to a common outlet 66, Fig. 4. The discharge from the outlet is directed forwardly and passes back over the tubes to apertures 76, Fig. 1, in tubes 75, and is discharged from apertures 77 and nozzles 78. A passage 50, Fig. 5, interconnects the combustion chambers, and one engine only has starting means, which means includes a spark plug 46 and a pressure air supply 47. To start the second engine a valve 51, which normally closes the passage when one engine alone is being used, is opened. A hand pump 80, for starting, applies pressure aid to a fuel tank 86, and supplies air to the starting engine. Fuel is fed to a float chamber 97 and then to the engine, and the spark plug is energized via a spark coil 103. When both engines are firing, pressure from the combustion chambers is fed to the fuel tank through pressure valves 111, 112, filter 117, pressure regulator 118 and check valve 121. A branch connection 125 leads to an atomizing liquid container 127, and liquid is fed through a line 130 to the engine exhaust tubes. Specication 673,481 is referred to.

Title: Process for preparing polymers and copolymers of vinyl chloride
IPC: C08F14/06
Filed: 1957-04-01
Abstract: Vinyl chloride is polymerized or copolymerized with lower olefins, e.g. ethylene, propene or butene, in the presence of a two component catalyst system comprising an organo-aluminium compound and a salt of the A sub-group IV to VI.  The organo-aluminium compound may be aluminium triethyl or an aluminium alkyl halide and the preferred salts are titanium and zirconium tetrahalides.  The polymerization may be conducted in liquid vinyl chloride or in a hydrocarbon solvent.  The aluminium component used in excess gives rise to unsaturated polymers which may be cross-linked by vulcanising agents. The polymers may be used in varnishes or to form films and threads which may be treated with ammonia, thiourea or amines to produce surfaces receptive to acid dyes.

Abstract: 747,532. Radio receiving systems. TESLA, NARODNI PODNIK. April 20, 1954 [April 30, 1953], No. 11409/54. Class 40 (5). Relates to automatic means for switching over a receiver to the other of a pair of receiving aerials when the signal strength falls below a predetermined level. In one embodiment the aerials 50, 51 are coupled to the receiver input 36 by valves 13, 14 respectively, one of which at any time is cut off. The receiver A.V.C. voltage is applied through terminal 113 to a control valve 8 which is cut off as long as the predetermined signal strength is exceeded. A positive voltage is thus applied from the anode 29 of valve 8 and contact 19 of a polarized relay 35 to the grid of triode 11 of a trigger pair 9, of which the triode 11 is conducting. When the signal strength falls to the critical value, valve 8 becomes conducting and valve 11 is cut off, the trigger pair 9 having its condition inverted so that the relay 35 is energized in the opposite sense. The output of valve 8 is therefore switched to contact 18 connected to the grid of valve 12 of the trigger pair 9 ready for another switching operation. At the same time, valve 13 which was rendered non-conducting by the connection between its grid and the anode 43 of the conducting valve 11 becomes conducting and valve 14 becomes non-conducting due to the connection between its grid and the anode 44 of valve 12, so that the signal is now derived from aerial 50 instead of aerial 51. A capacitor 34 across the relay 35 renders its time constant great enough to prevent more than one triggering action during the time constant of the A.V.C. stage.
