Abstract: 1,211,837. Model motor race track starter. ELECTRO-MECHANICAL DESIGN Ltd. 22 April, 1969, No. 20447/69. Heading A6S. A model motor race track starter operable by remote control comprises a hollow model human figure having a pivotally movable arm and electro-mechanically operated by linkage bearing directly on the armature of a relay such that raising and lowering of the arm is actuated simultaneously with the breaking and making, respectively, of a current supply to the race track. On closing a switch, coil 10 is energised causing a downward deflection, of pivoted relay armature 9 and allowing spring 7 to move rod 5 downwards with consequent (via lever 4 and rod 3) raising of arm 6, and allowing spring contacts d and e to break the current supply to the track. After a preset time lapse, determined by a variable potentiometer governing discharge of a capacitor coil 10 is automatically de-energised and the circuit returns to normal with the lowering of arm 6 and re-connection of the current supply to the track.

Abstract: 911,459. Endless belt conveyers. BOWATERSCOTT AUSTRALIA PTY. Ltd. June 16, 1959, No. 20644/59. Class 78 (1). Rolls of paper 9 are maintained in firmly rolled condition during transport on a conveyer belt 8 from a rolling-machine to a wrapping- machine by the provision of means for periodically transferring the rolls from the belt to a pair of rotating rollers 12 which are driven both in the same direction, i.e. that which causes rotation of the rolls in a sense which maintains their firmly wound condition. The transfer of the rolls from the belt 8 to the rollers 12 and vice versa is effected by supporting the conveying run of the belt 8 on idler rollers 18 each carried by a pair of arms 19 on a shaft 20, the shafts 20 being connected by a link rod 25 to a lever 26 operated by a cam driven from the wrapping- machine. As a result the conveying run of belt 8 is periodically raised, to lift rolls 9 clear of the rollers 12 and transport them towards the wrapping-machine, Fig. 4, and lowered, to deposit the rolls 9 on the rollers 12, Fig. 2.
Patent GB-206526-A (GB)
Abstract: 206,526. British Thomson - Houston Co., Ltd., (Assignees of Heisler, C. L.). Nov. 6, 1922, [Convention date]. Automatic circuitbreakers.-The operative element of a thermostat is constructed of a number of bars of two different materials arranged alternately side by side, one series of bars 11, Fig. 2, being of brass or like material having a relatively high coefficient of expansion and the other series being of steel, invar, or like material having a relatively low coefficient of expansion, the adjacent ends of the bars being connected by welding or brazing so that the movement of the end 14 of the final rod is the sum of the differences in expansion of the pairs of bars. Lateral distortion or bending of the bars is prevented by the provision of a casing 16 which surrounds the bars and guides their movements. Modifications are described in which the bars 11 are of I cr like section and completely enclose the bars 12, and in which the bars are replaced by series of concentric tubes. In the construction shown in Fig. 1, the thermostatic element is mounted on the wall 25 of an electrically-heated oven and. adapted to cut off the current when a predetermined maximum temperature is attained. The switch comprises an arm 31 normally held in closed relation to the contacts 36, 37 by the engagement of a latching lug 31<1> with a projection 30 on a pivoted arm 23, between which and the pivot 32 of the arm 31 a spring 33b is arranged tending normally to depress the right-hand end of the arm 23 and to move the switch arm 31 to the open position. When the predetermined maximum temperature is attained, the end 14 of the thermostatic element raises the right-hand end of the arm 23, frees the lug 31<1>, then allows the spring 33<b> to open the switch, resetting being effected by hand when the temperature has fallen sufficiently to allow the lug 31<1> and projection 30 to re-engage.

Patent GB-800160-A (GB)
Title: Process of producing anhydrous zirconium salts of organic monocarboxylic acids
IPC: C07F7/00
Filed: 1956-07-04
Abstract: Anhydrous zirconium salts of acetic acid and of fatty acids containing at least 4 carbon atoms in the hydrocarbon group are obtained by heating zirconium tetrachloride with an excess of acetic acid or with the equivalent quantity of fatty acid dissolved in an organic solvent, and distilling off the hydrogen chloride together with the excess of acetic acid or the solvent. The removal of hydrogen chloride may be accelerated by the passage of an inert gas such as carbon dioxide, nitrogen or dry air. Specified solvents are benzene, carbon tetrachloride and petroleum ether.  When preparing zirconium acetate it is advisable to react no more tetrachloride with excess of acetic acid than will ensure that the zirconium tetra-acetate remains in solution in the boiling glacial acetic acid. On cooling the acetate precipitates.  It may be dried by the passage of nitrogen or dry air at 110-130 DEG  C.  When preparing zirconium salts of the higher acids, the solvent is completely removed. Examples describe the preparation of anhydrous zirconium acetate and stearate.

Graduations 27 enable the readjustments to be effected uniformly. The pipe A having been lowered the upper nut 10 is turned the same amount as the lower nut 10 when the rollers 16 should support the pipe and allow it to be turned without undue friction. In order to allow for irregularities the pins 19 about which the rollers revolve are provided with eccentric portions controlled by the notched screw heads 20. Spring catches 21 retain the latter in their adjusted positions.

Abstract: 949,500. Space charge wave tubes. WESTERN ELECTRIC CO. Inc. June 14, 1960 [June 22, 1959], No. 20836/60. Heading H1D. A parametric amplifier has crossed electric and magnetic fields for focusing the beam means to cause signal energy to propagate along the electron beam as a fast cyclotron wave means for propagating an electromagnetic signal wave in coupling relation with the beam and in synchronism with the fast cyclotron wave and means for extracting the signal wave energy from the beam. The pump signal input and output circuits may be strip transmission lines or slow wave structures such as multicavity interdigital or serpentine structures. By suitable arrangements of directional couplers and filters the pump and signal output structure or the signal input and output and pump structures may be combined. As shown, a wire cathode 14 with wire accelerating anode 15 generates a flat beam. The length of plates 28, 32 is such that the Kompfner Dip condition obtains. 28, 32 need not be strip lines but may be constructed to support TM and/or TE modes. The input section 28 also strips noise from the electron beam. The pump circuit may be a quadrupole arrangement.

Title: Improvements in process and apparatus for the production of coke from inferior fuel
IPC: C10B1/04
Filed: 1922-08-02
Abstract: 205,257. Brandes, F. W. Aug. 2, 1922. Coking processes.-In obtaining hard coke from fuel such as non - bituminous coal, brown coal, peat, sawdust and the like, the fuel is impregnated with distillation products preferably from the oven into which it is subsequently charged. The passage of the distillation products through the fuel serves to dry and partially carbonize it before it is compressed', if desired, and charged into the oven. The fuel is supplied to an impregnating receptacle 2 provided with conical funnels 3, 5 for mixing purposes and leading to a coke oven 7, the distillation products from the oven passing bv a pipe 8 through the fuel in receptacle 2 the fuel being dried and absorbing the condensable constituents and the uncondensable gases escaping by a pipe 9. Compression before reaching the coke oven facilitates the formation of a hard coke and the coke oven may be worked at low temperature to give a semicoke. Tar may be added to accelerate the process and a poor fuel may be mixed with a rich fuel such as gas coal. Distillation products from a gas producer or another coke oven may be passed through receptacle 2 at the same time as the gas from the coke over 7 so that the receptacle 2 acts as a gas purifier or tar separator.
