Abstract: 476,953. Reciprocating pumps. MOORE, H., and CHARLTON, H. E. June 19, 1936, No. 17083. [Class 102 (i)] In a pump of the type in which pistons 4, 5 operate in communicating cylinders 2, 3, and the discharge is altered by adjusting the phase relationship of the pistons, the adjustment is effected by means of a hand wheel 30, which is carried by the spindle 12 of a bevelwheel 11 forming a component of the adjusting gear. The pistons are driven by connecting-rods from crank-pins 22, 21, carried by bevel-wheels 15, 16, which are geared together by the wheel 11. The pin 21 connects the wheel 15 to a worm-wheel 19, which is driven by a worm 26. The spindle 12 of the wheel 11 is rotatable about a pin 13 by means of a worm, which is rotated by the hand wheel and engages a fixed worm sector 25 provided with a scale. In a modification, the cylinders 2, 3 are in line, and the piston 4 is driven from a crank-shaft, which is driven from the pin 22 by means of a longitudinal shaft and bevel gearing.

INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, Now York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) June 19, 1933, No. 17460. Convention date, June 17, 1932. [Class 35] [See also Group XXXVII] The fluctuation of the current flowing through the commutator of a motor supplied through a rectifier is decreased by providing an auxiliary circuit which becomes effective when the rectifier output voltage is not greater than the motor back electromotive force. In the form shown, the armature winding 5 is fed from a single-phase source through a transformer 2 and anodes 9, 10 of the rectifier 3 and while the applied potential exceeds the back E.M.F. the potential of the auxiliary anodes 11-16 is negative in relation to the cathode, but when the current in the main circuit ceases due to a drop in the applied potential, a circuit is completed through the rectifier and winding 5 for the secondary current of transformer 17, the primary winding of which is connected to tappings on winding 5. In an alternative form, the star-connected winding connected to the auxiliary anodes and the brush 8 is on the motor rotor. The rectifier may be grid controlled, or the speed may be varied by step-by-step switches connecting the anodes 9, 10 to tappings on the transformer 2.

Title: A method of and apparatus for introducing wire into a surface treating chamber
Inventor: RUM KLAUS
IPC: B21C47/26
Filed: 1967-04-17
Abstract: 1,139,246. Blasting wire. DEUTSCHE EDELSTAHLWERKE A.G. 17 April, 1967, No. 17558/67. Heading B3D. A method of introducing wire into a surface treating chamber comprises successively separating turns of a coil of the wire without plastically deforming the wire, and feeding successive separated turns of the wire on to a revolving shaft passing through the said treating chamber, which shaft carries centrically mounted and axially spaced annular discs so that one separated turn of the wire lies in a gap between two adjacent discs, whereby the wire continually passes into the treating chamber on the said revolving shaft. A blasting chamber 2 contains rotating members for throwing sand or steel shot at wire for removing scale. A shaft 3 extending through the chamber carries spaced discs 4 and is driven from a cylinder 11, having fins 4<SP>1</SP>, through a step-up drive such that the peripheral speed of the shaft 3 is the same as that of the cylinder 11. At the inlet end, arms 6, 6<SP>1</SP> are carried by a column 5; each arm has a trough 7 extending lengthwise to receive the mandrel of a loading device. A wire coil, e.g. two or more coils with the corresponding ends welded together, is loaded on to the outermost arm which is then brought into register with the cylinder 11 and coupled to it for rotation therewith by a pin 8 actuated by a compressed air cylinder. The leading end of the wire coil 1 rests against a blade 12 mounted in axially adjusted position on a shaft 14; the blade cannot move towards the chamber 2 but can yield in the opposite direction. In the viscosity of the end of the arm is a plate 15 engaging between consecutive wire turns 13; two such plates are preferably provided, one on each side of the arm and relatively staggered. The leading end of the wire is placed by hand into the first spaces between the discs 4 on the shaft 3 and the spaces between the fins 4<SP>1</SP> of the cylinder 11, each space containing only one turn. Rollers 17 are urged by springs 18 into the spaces between the fins 4<SP>1</SP>, and may be driven. A shaft 19 prevents the wire spring- ing out of the spaces between the discs 4. Presson rollers are also provided at 20, 21; these may be omitted and the shaft 19 extended. At the outlet end of the shaft 3 the separated turns ride on to an arm 22 tilted upwardly by a cam 24 and coupled by a cylinder 25 to the shaft 3 for rotation therewith. The wire is then cut, the arm 22 swung away and the empty arm 22<SP>1</SP> swung into receiving position-. Driving rollers 26 may be provided near the blade 12 for positively drawing the wire out of its coil. A lever 27 may be provided, ahead of the blade 12, pivoted on the shaft 14 to loosen the coil by jolting it from underneath. The path from the chamber to the delivery unit may include pickling, rinsing and phosphating vats and drying chambers.
