Patent GB-137073-A (GB)
Title: System for the transmission of electro-radiant energy
IPC: H01Q9/04
Filed: 1919-12-24
Abstract: 137,073. Kolster, F. A. Nov. 27, 1916, [Convention date]. Wireless signalling; aerials and like radiating and receiving conductors. - Energy is radiated from a coil, Fig. 1, of one or more turns, of small dimensions and having very small capacity and distributed inductance, in circuit with a condenser. The radiating circuit is of low resistance and is stated to be free from any tendency to re-inforce harmonics of the fundamental frequency. The energy is radiated most strongly in the plane of the coil, which may be rotatable, and the directional effect may be accentuated by giving the coil a long form, as shown at A in Fig. 8, and replacing the condenser by an elongated pair of capacity areas K, K<1>. A separate condenser C<2> may be provided in this case for tuning. With two coils connected in series and arranged at right-angles the direction of maximum radiation bisects one of the angles between the coils. The energy may be produced by a spark generator as in the apparatus shown in Fig. 1 or by an arc, signalling being effected in the latter case by varying the tuning of the circuit by a key which shortcircuits an auxiliary inductance. Radiating-circuits of the kind described may be used also for receiving signals. Specifications 11575/97 and 11582/07 are referred to.

Filed: 1959-09-24
Abstract: 891,503. Light-weight slag aggregate. DOW CHEMICAL CO. Sept. 24, 1959, No. 32548/59. Classes 22 and 87(2). [Also in Group II] A light weight aggregate is produced from molten slag by dispersing particles of carbonaceous material with the slag and cooling rapidly. The carbonaceous material may be bituminous coal used at the rate of 3À75-15 Kg. per 1,000 Kg. molten slag, or it may be sodium carbonate and/or bicarbonate.

Title: Control circuits
IPC: G05D23/24
Filed: 1973-07-09
Abstract: 1432024 Automatic control of temperature WAYNCO Inc 9 July 1973 32582/73 Heading G3R In the temperature control of an electric heater, the heater is connected in a bridge circuit and in effect functions also as its temperature sensor. A sampling pulse is applied periodically to the bridge and any deviation from a desired temperature produces an output from the bridge which controls a power transistor in series with a main power supply to the bridge and heater. In Fig. 1, the desired temperature for a heater 11 is pre-set on R45. A pulse 31 Fig. 3 is produced by a pulse generator 13 substantially at zero voltage crossings of A.C. supply, being initiated at 5 volts before zero and terminating at 5 volts after zero. Each pulse 3 1 switches ON transistors 38, 39, 40 momentarily to conduct a sampling pulse 41 Fig. 4 to the bridge. If the heater temperature, is below the set temperature then the sampling pulse will appear more positive at Y than at X so that an amplifier 46 with positive feedback will switch to its most positive output which is applied to switch ON transistors 38, 39, 40. Full wave rectified unsmoothed D.C. voltage Fig. 6 will then be applied to the bridge including heater 11 until the temperature of the heater increases to a level whereat the potential at Y is slightly less than that at X causing the transistors 38-40 to switch OFF. The power control transistor will then stay OFF until the next sampling pulse causes them to switch ON momentarily. Since the power transistors will be switched ON by the amplifier 46 in response to a temperature sensed during a sampling pulse, the supply of full power to the heater will be initiated substantially at zero voltage crossings (e.g. when the voltage drops to 5 volts before zero). Excess load current is sensed by an amplifier 53 connected across R42, which amplifier switches ON a transistor 59, thereby blocking control current to 38, 39, 40 so that the heater is deenergized. The amplifier 53 will be latched in its more positive output mode by positive feedback and will not unlatch until the supply is removed there from. Where the supply is D.C. it is caused to fluctuate by a relaxation oscillator Fig 7 (not shown) which determines the sampling pulse rate.

Title: A process for modifying the physical characteristics of argillaceous soils
IPC: C09K17/02
Filed: 1937-11-26
Abstract: 512,763. Electrolytic treatment of soil. RODIO, G. Nov. 26, 1937, No. 32730. Void. Convention date, Nov. 28, 1936. [Class 41] [Also in Group XXI] Physical characteristics of argillaceous soils are modified by injecting into the soil a liquid containing ions capable of substituting themselves for the ions present at the surface of the particles of clay and having an affinity for water different from that of the replaced ions. Thus, water may be freed from a clay rlch in sodium carbonate by injecting cement, free lime or an aluminium salt in solution or suspension, and the process may be assisted by treating the soil electrically, as by a continuous current using an aluminium electrode ; freed water may be left in situ or removed by electro-osmosis, or creation of a hydraulic gradient. Similarly, clay poor in Na2O may be consolidated by injecting caustic soda, sodium carbonate, sodium silicate &c. so as to increase the amount of water absorbed.

Filed: 1960-09-23
Abstract: Silicon is deposited from a gas or vapour on to a rod of silicon heated by induction and held at each end by a support maintained at a temperature below that at which impurities, which would <PICT:0908373/III/1> <PICT:0908373/III/2> render silicon unsuitable for use as a semi-conductor, would be evolved.  The silicon may be deposited from a mixture of hydrogen and silico-chloroform or silicon tetrachloride.  The rod of silicon may be at a temperature of 1100 DEG -1350 DEG C. during deposition.  Quartz supports are maintained at below 800 DEG C.  The rod may be freed from surface contaminations by etching and then heating in the reaction chamber to 1200 DEG -1400 DEG C. for at least a quarter of an hour in a vacuum or hydrogen. The rod may be preheated before induction heating by radiation or by the introduction into the reaction chamber of hot hydrogen or inert gas.  As shown in Fig. 1, the reactant gas passes through inlets 5 into an annular chamber 1 surrounded by an induction heating coil 4 and thence through orifices 6 into an inner chamber 1b which contains a rod 2 having supports 3 outside the field of the induction coil. As shown in Fig. 2, the reactant gas passes from a tube 11 via orifices 6 to a reaction chamber 1 containing a rod 2 having water cooled supports 3 outside the field of the induction coil.
