Abstract: 533,835. Coating bodies with glass or other fusible mineral substance. BRITISH THOMSON-HOUSTON CO., Ltd. (Tokyo Electric Co., Ltd.). Dec. 4, 1939, No. 31422. [Class 56] [Also in Group XXXVI] A method of coating a body such as a wire with fusible mineral substance, particularly glass or quartz, consists in producing a fibrous form of the substance by squirting fused material with the aid of gas under pressure, and causing the fibres so produced to impinge on the body while they are still in a viscous state. Fibres having a thickness of less than six microns may be deposited on a wire to form a resilient, insulating coating. A glass rod 2 may be fed at a pre-determined rate through an electric heater R to a nozzle 1. Compressed air blown through the nozzle projects the glass in the form of a spray of fibres 3. A body, such as a wire 4, is progressively exposed to contact with the glass fibres and receives a coating 5 which may be heated by flames 6 to fuse its surface.

Abstract: 716,596. Automatic current control systems. LICENTIA PATENT-VERWALTUNGS-GES. Dec. 17,1952 [Dec. 17, 1951; Feb. 21, 1952], No. 31989/52 Class 38(4) The current in a load circuit (particularly a welding circuit) supplied from a frequency multiplying transformer having a Scott connected three-phase primary and a single-phase secondary as disclosed in Specification 714,146, [Group XXXII], is maintained substantially constant by varying the saturation of the transformer core in accordance with either load current or load voltage. In addition to the primary and secondary windings (not shown) the transformer V, Fig. 2, has opposed saturating windings. H, G. The reference winding H is energized over rectifier G1 from the supply mains and the winding G is energized by the amplified resultant of a voltage proportional to load current derived from current transfomer S and rectifier G2 and a reference voltage derived from rectifier G3. Thus any increase in load current reduces the nett saturation to restore the current to the required value. In another embodiment, Fig. 5, the primary and secondary windings are again not shown and the reference winding H is aided by the winding Z which is energized over a rectifier in accordance with the load voltage. A choke Dr operating in its non-leiriear range may be included to improve the accuracy of regulation.

Title: Drawbench apparatus
Inventor: MITCHELL GEORGE ANSLEY
IPC: B21C19/00
Filed: 1964-08-07
Abstract: 1,080,134. Drawing. G. A. MITOHBLL. Aug. 7, 1964, No. 32297/64. Heading B3P. A drawbench has means for dissipating the kinetic energy produced when the trailing end of a workpiece leaves the die, the said means comprising a pair of members arranged to frictionally engage the workpiece between the draw carriage and the die. A tube is drawn through a die 20 by a draw carriage 26 which has gripper jaws 50. The jaws are closed by a pneumatic cylinder 55 which actuates a pivoted lever 58. The part of the tube between the die and carriage is engaged by a pair of rollers 62, 64, mounted in pivoted arms 66, 68 and movable into and out of engagement with the tube by fluid cylinders 74, 78. Each of the rollers comprises a metal hub 86, Fig. 6, a rubber or neoprene tyre 88 and a plate 90 screwed on to the hub 86. The assembly is mounted on a fixed shaft by ball races. The plate 90 is formed on its periphery with axial slots 114, and positioned close to the plate is an E-shaped core which has windings 110, 112. When the coils are energized and the plate 90 is rotating, the magnetic lines of flux will create eddy currents which produce a braking effect on the plate. On opposite sides of the tube as it emerges from the die are a light source 116 and a photo-cell 118 which is connected to a control circuit associated with the core. As the tube is being drawn the rolls 62, 64 rotate freely, but as the end of the tube leaves the die, the light source 116 activates the photo-cell 118 and the coils 110, 112 are energized. The kinetic energy of the tube is dissipated before the trailing end of the tube passes through the rolls. The tube comes to a halt with the heading and trailing ends resting on a table (134), Fig. 4 (not shown), beneath the drawbench and with an intermediate portion engaged by the rolls. In the embodiment described three tubes are drawn simultaneously and the features described above are triplicated, so that each tube is controlled independently of the other tubes. When all the tubes have left the dies the cylinders 74 and 78 are operated to move the rollers away from the tubes, the lower rollers being moved to a position below the table (134), which is then tilted by a linkage so that the tubes roll into a bin. Due to the action of the rollers 62 and 64 the trailing ends of the tubes are substantially aligned. In the case of thin tubes where the drawing tension approaches the breaking strength of the tube it is essential that the rollers should rotate freely and not impose additional drag on the tubes, but in the case of thicker tubes the electromagnetic braking devices may be replaced by friction brakes (164), Figs. 9 and 10 (not shown) on each roll, which act throughout the drawing operation. In order to ensure that the rollers 62 and 64 are symmetrically disposed above and below the axis of the dies and do not deflect the tube between the dies and the drawcarriage, the lower roller is positioned by an adjustable stop and the pressure in the cylinder 74 is greater than the pressure in the cylinder 78.

Amino-acids are separated by electro-dialysis, in which the mixture is introduced into a compartment of a multi-compartment cell, bounded by an anionic permeable membrane and a cationic permeable membrane, adjusting the pH of the mixture to the iso-electric point of one acid to be retained, the others moving to the anode and cathode. Preferably the multi-compartment cell is tubular in shape, with circular diaphragms and electrodes. The pH values of anolyte and catholyte compartments are respectively higher and lower than that of the central compartment. In the case of a mixture of two only of amino acids, the mixture may be introduced directly into either the cathode or anode compartment at a suitable pH value, the central mixture compartment being then unnecessary. In a mixture of 3 or more acids, the pH values may be adjusted to (1) central compartment 5.5 to 6; (2) anode compartment 8 to 9; (3) cathode compartment 1 to 3. In examples, the mixtures separated are: histidine, lysine, arginine with traces of glutamic and aspartic acids ; hydrolysates of proteins are also referred to.
