Title: Improvements relating to sluices and regulating means for rivers, canals, and other waterways or storage works
IPC: E02B7/20
Filed: 1943-12-17
Abstract: 574,037. Sluice-gates. ANDREWS, F. M. Dec. 17, 1943, No. 21249. [Class 68 (ii)] [Also in Group XXIX] In means for automatically controlling the opening of a sluice gate by a counterbalance vessel or vessels loaded by the contained water, the vessels operate the gate through torque-varying means which vary the effort ratio between them and the gate in accordance with the opening of the latter, whereby instability and hunting in the operation of the gate are avoided. As shown, a sluice gate 14 carried by arms 15 pivoted at 16 is suspended by chains 19 from conical pulleys 20 on a shaft 21 which carries further conical pulleys 22 for the suspension chains 23 of counterbalance vessels 24. When the contained waterrises to a predetermined level above the gate it flows through an adjustable notch or orifice in a control box 30 into the vessel 24, which is provided with an adjustable outlet notch 43. As the vessel sinks and raises the gate its lifting effort on the gate diminishes owing to the conical pulleys 20, 21, so that a point of balance is reached dependent upon the height of the contained water. As shown, the notch 31 in the control box 30 is formed in a vertically-adjustable plate 29 and its area is adjustable by a pivoted plate 32, adjustments being effected by levers 35, 36 through a rotatable and longitudinally movable shaft 34. The height of the plate 29 determines the level of the water at which the sluice gate 14 begins to open, and the adjustment of the pivoted plate 32, the extent to which the gate is opened for a given further rise in level. A hand gear is provided for moving the gate, and is brought into operation by a clutch 41. In a modification, spiral pulleys replace the conical pulleys 20, 21 and the notch 31 is dispensed with, water being admitted to the control box by an adjustable stand pipe and passing from it through a flexible pipe to the vessel 24. The outlet from this vessel comprises a vertical pipe with a slit down its side and internal and external adjustable sleeves to control it. The sides of the sluice gate are staunched by metal strips 64, Fig. 7, secured to it with interposed elastic packing 66 and carrying brass or copper fillets 69 which bear against arcuate staunching members 67 secured in the walls of the sluiceway.

Title: An improved system of wireless control
IPC: H04K1/02
Filed: 1923-08-22
Abstract: 224,621. Vickers, Ltd., and Ryan, C. P. Aug. 22, 1923. Controlling distant apparatus; secret and selective signalling systems; thermionic modulating systems. - In a system for the wireless control of distant apparatus, transmission is effected by a phonographic or like sound record Q impressed with control signals of acoustic frequency repeated at definite intervals, and with confusing signals of other acoustic frequencies. The reproducing needle R operates a microphone N, the circuit of which is coupled to the grid circuit of a valve L. The plate circuit of this valve includes a source O and a choke coil P, both of which are also in the plate-supply circuit of an oscillating valve K energizing the aerial J. The low-frequency potentials across the choke P are thus impressed on the oscillator plate, and result in a modulated oscillatory current in the aerial. A high-frequency choke coil P<1> is inserted between the two plates. The receiving-mechanism is of the kind in which the received signals after rectification are converted into sound waves which pass through an acoustic resonator. They are then converted into current impulses which operate a vibrating structure at its natural period of vibration.

Abstract: 1,118,514. Electro-magnetic forming of coils. GENERAL ELECTRIC CO. 8 May, 1967 [28 July, 1966], No. 21343/67. Heading B3A. A metho in a magne in a carrier a predetern station; transferring the coil into predetermined slots in the core; establishing electromagnetic forces in the vicinity of the wound coil at a press-back station adjacent the core-receiving station with the core in the carrier thereby to press back at least portions of the coil. A stator core 10 is mounted in the core carrier 14 at the receiving station 12 and the coils are wound at the winding station 13. The wire 38 is fed to a winding flyer 36 from a spool 40 and it is wound on a stationary form 42, which has five portions 44, 46, 48, 50 and 52 to form coils of different sizes. When the coil has been wound the carrier 14 is moved to the station 13 and a coil insertion mechanism (not shown) inserts the turns into predetermined slots in the core 10. The carrier is withdrawn, a conductor carrying structure 78 is advanced on a pair of tracks 82, 84 and the carrier 14 is advanced again so that the core 10 is placed over the structure. Conductor bars 118, 120, 122 fit into opposed slots in the core and are serially connected, the structure 78 having an insulated coating or sheath 116 and is made of non- magnetic material. The free ends 136, 138 of the coils are joined together and the conductor bars are connected to an electrical energy surge source 94, which injects a surge of energy therein, whereby an interaction of electromagnetic forces is set up which presses back the coil portions in the slots and the end turn portions. The free ends 136, 138 are then connected to the source 94 and the pairs of conductor bars 118, 120, 122 shorted together. A surge of energy is injected into the coils, which are compacted to their fully developed position. While the coils are being compacted at the station 15 further coils at the same time may be wound at the station 13 for insertion in a further core or in the core 10 for further coil development. In an alternative embodiment a single station replaces the separate core-receiving and press-back stations 12, 15. In a further embodiment a structure (79) is provided, similar to the structure 78, but without conductor bars, and is meant only to affect the electromagnetic forces developed when a surge of energy is passed through the coils.

Abstract: 1,154,741. Silver bromide. FAIRCHILD CAMERA & INSTRUMENT CORP. 13 May, 1966 [17 May, 1965], No. 21375/66. Heading C1A. [Also in Divisions C7 and G2] Ultra-pure, light-insensitive AgBr having a specific electrical conductivity of not more than 10-<SP>8</SP> reciprocal ohm-centimeters when measured at 22‹ C. in an atmosphere of less than 1% relative humidity, and an impurity content of not more than 1 part in 10<SP>6</SP> parts, is prepared by reacting silver and bromine in an apparatus as shown in Fig. 1. Flask 10 contains purified bromine. Highly pure silver is placed in reaction cup 16. The apparatus is evacuated overnight at approximately 450‹ C., and degas the silver. The break-seal 13 is broken and bromine distilled to cup 16 and reacted with the silver at approximately 500‹ C. The liquid AgBr formed is filtered by dropping through the filter cups 23. On completion of the reaction, a small amount of bromine is frozen into side arm 25 and flash 10 sealed off. The molten AgBr in 26 is evacuated for 3 hours at approximately 450‹ C. to decompose any silver oxides present, and then the AgBr is rebrominated with the bromine in side-arm 25. The AgBr is cooled very slowly, to room temperature, in an atmosphere of bromine to prevent the AgBr sticking to the sides of 26 during cooling and contracting. A small quantity of bromine was vaporized from 25<SP>1</SP> to 26 and the latter sealed off so that the pure AgBr is sealed in an atmosphere of bromine. The AgBr is purified by conventional zone-refining. The AgBr may be vapour deposited on a suitable support in the presence of doping agents, the AgBr may be made light-sensitive. An apparatus is described in which a pure AgBr layer may be vapourdeposited, or the AgBr may be previously deposited on the support and exposed to the vapour of the doping agent, or the AgBr and doping agent may be vaporized simultaneously. For continuous operation, high-vacuum coating devices of known structure may be utilized. The materials to be vapour-deposited are contained in a boat of a trapezoidal cross-section, and a more uniform coating is achieved by using a boat with an internal side-to-bottom angle of 105 degrees and ends substantially perpendicular to the base. In an alternate procedure, the doping agent may be placed in tube 26 of the apparatus on Fig. 1, and AgBr distilled into this tube and the tube sealed off. The mixture of AgBr and doping agent so obtained is subjected to levelling using a zone-refining apparatus preferably with one heating coil. This enables the doping agent to be distributed in the AgBr. The doping agent or agents are each a metal from Groups VIII, I B , II B , III A  and III B  of the Mendeleev periodic table of elements or a salt of such a metal.
