Title: Improvements relating to pulse generators
Inventor: MIDDLETON JOHN FRANCIS

Filed: 1964-05-13
Abstract: 1,103,825. Capacitor supply systems for discharge lamps. ELECTRIC & MUSICAL INDUSTRIES Ltd. 13 May, 1965 [13 May, 1964], No. 19867/66. Heading H2H. [Also in Division H3] In a pulse generator of the type in which a capacitor or pulse forming network 13 is charged from the rectified output of a transformer coupled relaxation oscillator and subsequently discharged via a switching device (such as 14), the switching device is triggered by a signal induced in a winding of said transformer during the intervals in which the capacitor is not being charged. As described transistor 6 is regeneratively coupled by windings 4, 7 of a transformer so as to form a freerunning of triggered blocking oscillator, the duration of pulses from which is determined by the time taken for the current in winding 4 to reach a value such that transistor 6 is no longer saturated. Each high voltage pulse from the secondary winding 10 resonantly charges an artificial line 13 via a diode 11 which is subsequently discharged via a thyristor 14 and a pulse transformer 15 feeding a magnetron load 2. Thyristor 14 may be triggered by the next pulse from an auxiliary winding 17 after amplification, delay or differentiation at 18. The thyristor 14 may be replaced by a triggered or non-triggered spark gap or a thyratron. H2H: Electricity supply to flash tubes.-The invention may alternatively be applied to a Xenon flash tube which may be connected in place of thyristor 14.

Patent GB-627376-A (GB)
Title: Improvements in or relating to the production of chlorinated polythene
IPC: C08F8/20
Filed: 1947-07-25
Abstract: Chlorinated polythene is made by polymerizing ethylene at p  elevated temperature and pressure, ejecting the polythene into cooling water at substantially atmospheric pressure, preparing from it uncompacted polythene of particle size less than 36 B.S. mesh, suspending it in water and passing chlorine gas through the suspension maintained at 40-100 DEG  C. in a state of agitation.  The suspension is preferably irradiated with actinic light of wavelength 2800-5500 A.  At least 9 parts of water to 1 part of polythene is preferably used and 25-30 parts of water if a product having more than 45 per cent by weight of chlorine is to be prepared.  The suspension is improved by the presence of a small amount of a wetting agent, e.g. sodium lauryl sulphate, and of calcium chloride.  The ethylene may be polymerized in the presence of water, benzene or chlorbenzene, oxygen and an alkali at a pressure of 500-1500 atmos. and at 150-275 DEG  C.  On ejecting the polymer at atmospheric pressure, the liquids expand the polymer leaving it in a porous, spongy form.  If necessary, the polythene is then comminuted and screened to the desired particle size.  The chlorinated polythene should be washed with distilled water which may contain anti-acids and anti-chlors.  The products may be made into films, sheets, tubes and filaments for use in luggage articles, raincoats and food coverings, and are useful in electrical and mechanical applications.  They may also be used as impregnants, e.g. in solution in volatile chlorinated solvents, for fabrics for fungi, water and fire protection.  Valuable blends are also produced by mixing with synthetic linear polyamides and with vinyl acetate and vinyl chloride polymers.  Specifications 576,119 and 592,487 are referred to.

Title: A process of decomposing salts of complex hydrofluoric acids
IPC: C01B33/08
Filed: 1927-07-28
Abstract: 303,760. Meyerhofer, A. F. July 28, 1927. Rotary furnaces; roasting furnaces.- Complex fluorides such as sodium, potassium, or barium silicofluorides are decomposed to form a metal fluoride and a volatile fluoride by heating in thin layers in a partial vacuum. The material is rapidly brought to a decomposition temperature to avoid partial sintering. Neutral gases or vapours such as air, steam, oxygen, flue gas, producer gas, etc., may be used to accelerate the removal of the gaseous fluoride, or solid or liquid substances which volatilize during the heating may be used. The heating may be carried out in a rotating or oscillating furnace comprising a central reaction tube b Fig. 1 surrounded by an annular chamber a heated by burners g. Additional burners for supplying hot gases to the chamber a at various points along its length may be used. The tubes, gas-supply pipes etc. may be mounted upon each other by means of springs. The heating may also be effected by passing the material down a cone a Fig. 7 or onto a horizontal rotating disc heated from below by a gas burner h, a device for producing flameless combustion or an electric heater. Suction is applied to the gas outlet h to produce a partial vacuum in the reaction chamber. Specification 249,860, [Class 1 (iii), Oxides &c., Metallic], is referred to.

Filed: 1921-08-03
Abstract: 167,485. Soc. Anon. des Forges et Ateliers de la Fournaise. Aug. 4, 1920, [Convention date]. Steelyard apparatus; sliding-weight apparatus. -In an apparatus for weighing, or for measuring the pull of absorption dynamometers, the load is applied by means of an encircling collar to an eccentric portion of a trunnion forming the fulcrum of a lever carrying a sliding load-balancing weight. Automatic electric means may be provided for adjusting the load-balancing weight to equilibrium position. The apparatus shown in Fig 5 is suspended by a rod 3<1> and the load is applied to a rod 4<1>. Suspended from the rod 3<1> are two levers 15 mounted on ball-bearing trunnions 12<1> in links 9. Eccentric portions of the trunnions support links 11 connected to the load rod 4<1>, ball bearings being interposed between the eccentrics and the links. When a load is placed on the rod 4<1> the outer ends of the levers 15 rise but may be returned to equilibrium position by adjusting the sliding weights 16 by hand, or preferably by automatic mechanism described below, the magnitude of the load being ascertained by graduated scales of the levers. The automatic mechanism comprises a continuouslyrunning electric motor 17 with two friction rollers 19 situated within annular grooves formed in drums 25. The heads are rotatable in heads 24 constituting the inner ends of the levers 15. The rotations of the drums are transmitted by gearing 22, 21 to screws 20 which traverse the sliding weights 16 a'ong the levers. In the position of equilibrium of the levers the rollers 19 are out of contact with the drums 25 but tilting of the levers produces contact and results in adjustment of the sliding weights until equilibrium is attained.
