Abstract: 838,125. Band brakes. MASCHINEN-UND ZAHNRADERFABRIK GOTHA VEB. July 19, 1957, No. 22914/57. Class 103 (1). A planetary gear system is braked by means of a band 19 to a point near the middle of which there is secured a rod 9 coupled to a piston reciprocable in a cylinder 6. As a result of friction between the band 19 and central wheel 18, the movement of the band causes the piston 3 to cover ports 10 in the cylinders so that flow of oil from a pump 11 is prevented from escaping and the pressure acting against pistons 1 and 2 in main actuator cylinders 4 and 5 is increased, thus causing a torque which balances the torque on the central wheel.

Abstract: 713,346. Gas turbine plant. DAIMLERBENZ AKT.-GES. Oct. 3, 1951 [Oct. 1, 1948], No. 23081/51. Class 110(3) [Also in Group XXXI] In a vehicle with a gas turbine propulsion unit comprising a compressor driven by a turbine and a mechanically independent power turbine disposed one behind another longitudinally of the vehicle, the transverse wheel shafts of the vehicle are arranged to be directly driven by a longitudinal shaft from the power turbine which is designed to rotate at such a low speed that it can drive the vehicle wheels without a substantial reduction ratio. The expression "directly driven" is intended to refer to arrangements in which the transverse wheel shafts or the differential gearing between these shafts are driven by the longtitudinal shaft through a simple gear. In particular, there is no other gearing serving as reduction gearing. In the arrangement shown air from an axial flow compressor d is supplied to combustion chambers b to which fuel is fed through nozzles a. The combustion gases from the chambers b are led to a turbine f driving the compressor a and the fuel pump h and then to a mechanically independent power turbine g. The driving shaft or shafts I of the vehicle wheels are directly driven by the turbine g through a shaft g<SP>1</SP> and a simple bevel gearing i and, in some cases, a differential gearing k. The turbine f is smaller than and rotates faster than the turbine g.

Title: Production of Ferrovanadium from Vanadium-containing Materials
IPC: C22B7/04
Filed: 1968-05-17
Abstract: 1,165,487. Ferrovanadium. CHRISTIANIA SPIGERVERK. May 17, 1968 [May 31, 1967], No.23650/68. Heading C7D. In a two stage reduction process for the production of ferrovanadium from vanadium oxide - and iron oxide - containing materials, the material is first treated with enough reducing agent to reduce a substantial proportion of the iron oxide to metal, while leaving the oxide of vanadium unaffected. The metallic iron is separated and the residue reacted with a powerful reducing agent to reduce the remaining iron oxide and most of the vanadium oxide to metal, thus obtaining ferrovanadium alloy. A useful alloy source is pig iron slag and suitable reducing agents contain silicon in large proportions. In the first stage reduction is conveniently carried out at 1550- 1750‹C. with 75 per cent ferrosilicon, and the second stage employs 90 per cent ferrosilicon, silicon, calcium-silicon or aluminium-silicon or mixtures of these, at 1600-1700‹C. For best vanadium recovery the slag is maintained moderately basic with a CaO;SiO 2  ratio of 1À0-2À0, and very fluid by additions of 2-10 per cent of MgO and 2-20 per cent of Al 2  O 3 .

Title: Improvements in and relating to a method and apparatus for filling bottles and like containers with liquid
Inventor: FRIENDSHIP KENNETH FRANCIS MON
IPC: B67C3/18

Abstract: 790,506. Bottling. MEYER LIQUID, Ltd. [formerly LIQUID CARBONIC CO., Ltd.]. May 15, 1956 [Aug. 18, 1955], No. 23798/55. Class 125(2). Relates to machines of the kind described in Specification 650,454 in which a bottle &c. is filled under pressure by syphonage from a supply tank the liquid level in which is in line with the desired filling level in the bottle, the syphon action being initiated by applying to the bottle a lower counterpressure than that of the liquid supply and a pressure equal to that of the supply being applied to the bottle after filling for levelling purposes. According to the invention, the filling is carried out in two stages, a slow filling stage against relatively high counter-pressure and then a fast filling stage against a lower counterpressure, the latter taking up the major portion of the filling operation. As shown, a tank 1 is divided by partitions 3, 4 into three concentric spaces in the outer of which the supply liquid is maintained at level L, this space being connected through filling valve 18 to the bottle 19 through pipes 21, 22. Outer and inner cylinders 7, 9 depend into the intermediate and centre spaces respectively, these spaces containing water or other liquid. High pressure gas is supplied through pipe 14 to the space 13 between cylinder 7 and portion 4 and by bubbling under cylinder 7 it maintains a head of liquid V outside the cylinder so that the pressure in space 13 is greater than the liquid supply pressure. The liquid supply pressure is transmitted to the inner cylinder 9 by aperture 11 and maintains in space 17 between the cylinder 9 and partition 4 a pressure lower than the supply pressure by the height of liquid column W. In operation, the bottle being sealed to the filling head and the syphon having been primed, the bottle is brought into communication through pipe 15 with space 13 and filling takes place slowly against the relatively high counterpressure. Valve 18 is then actuated so that the bottle communicates through pipe 16 with space 17 and filling takes place rapidly against the low counterpressure. Valve 18 is again actuated so that the liquid supply pressure reaches the bottle through pipe 20 and levelling takes place. A controlled bleed of gas from space 17 may be permitted through pipe 23.

Abstract: 390,165. Automatic regulation ; converting ; phase-changing. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thompson, L. W. ; 53, Baker Avenue, Schenectady, New York, U.S.A.) Aug. 27, 1931, No. 24141. Convention date, Aug. 28, 1930. [Classes 38 (ii) and 38 (iv).] Comprises a voltage-regulation system, in which an induction regulator is adjusted by means of a reversible motor connected across one diagonal of a Wheatstone bridge having saturable reactors in two of its arms, the saturation of which is controlled by means responsive to the voltage of the supply to be regulated so as to unbalance the bridge and vary the direction of current flow through the motor. A reversible motor 4, adjusting an induction regulator 3, is connected across one diagonal of a Wheatstone bridge composed of four saturable reactors 10 .. 13, the other diagonal of the bridge being connected to the mains 1. The parallel connected saturation windings of reactors 10, 11 are supplied with rectified currents from a valve 28, connected to the secondary 32 of a transformer 33. Similarly the saturation windings of reactors 12, 13 are supplied from a valve 27 connected to the secondary 32. The grid potentials of valves 27, 28, are 180‹ out of phase, and are obtained from the secondary of a transformer 43, the primary of which is supplied from a centre tapped winding 40 on transformer 33 through branch circuits containing a resistance 41 and a variable reactance 42. The impedance of the reactor 42 is varied in dependence on mains voltage by an iron wedge 50 which is moved by means of a coil 52. Variation of the impedance of the reactor 42 ensures a difference of phase angle between the potentials applied to the grids of the valves 27, 28 and the supply potential, so that one or the other of the valves passes more current and the balance of the bridge is upset and current flows to cause the motor to rotate in one direction or the other to effect regulation.
