Abstract: 517,484. Current measurements. BRITISH SANGAMO CO., Ltd., (Weston Electrical Instrument Corporation). July 29, 1938, No. 22627. [Class 37] The internal wiring of an instrument is arranged to afford protection against pick-up of stray currents from high-frequency alternating electric fields by forming the internal leads between the moving coil and the source of current therefor as a tubular conductor through which the other conductor passes. In the thermal ammeter shown a permanent magnet 2 is mounted on a base 1 and carries upper and lower bridges 5<1> on which the moving system is pivoted and through which the connections to the moving coil 3 are made. Massive metal blocks 6 carrying the heater 7 are carried by main terminals passing through the base 1. The hot junction of the thermocouple 10 is located at the midpoint of the heater 7 the cold ends being soldered to compensating strips 11, 11<1> carried at each end by the blocks 6 but insulated therefrom by thin mica sheets 12. A short tubular conductor 13 is soldered to the upturned end of the compensating strip 11 and to a bracket on the lower bridge. Passing through the tube 13 is a wire 15 soldered to the compensating strip 11' and a bracket 14 on the upper bridge 5', the wire being bent around the magnet 2 to reach the upper bridge. The soldered terminals of the strips 11, 11<1> are adjacent to each other and symmetrical with respect to a plane passing through the main terminals. The plane of the concentric conductors 13, 15 is normal to the current path through the heater 7 between the main terminals. In a modification the exposed portion of the central wire is reduced by arranging both the springs for making connection to the moving coil at one end of the coil.

Abstract: 244,540. Peto, W., Genese, H. M., and Pritchett & Gold & E.P.S. Co., Ltd. Sept. 26, 1924. Cells; separators.-An accumulator cell is provided with a porous partition or separator shaped to provide two chambers of different sizes or shapes in which the electrodes are placed, the electrodes being also of different sizes or shapes and corresponding to those of the chambers. Figs. 2 and 3 show in plan two forms of separator b in a cylindrical cell a. In Fig. 2 the chambers c, d which receive the electrodes are of different shapes. The separator may be shaped to provide additional chambers h to receive electrolyte. In the form shown in Fig. 3, the separator fills the containing cell except for two cylindrical compartments c, d of different sizes for the electrodes. In a further modification for use with a rectangular cell, the partition is straight and provided at the ends with flanges which are of different thicknesses on the two sides of the partition, thus making the compartments into which the cell is divided of different sizes. One corner of the cell and the corresponding corner of the partition may be bevelled to prevent the partition from being inserted incorrectly. A number of cells may bo moulded in one together with end plates i as shown in Fig. 4, lips or flanges e<1> being subsequently attached to the upper ends of the cells.
Patent GB-228069-A (GB)
Abstract: 228,069. Jones, T. H. July 15, 1924. Circular machines ; stop-motions.-A device for preventing " press-off s " on failure of yarn consists of a rotatable post 2, an arm of which supports a vertically slidable needle cam 16 through the intermediary of a lever 12 while an upper arm 6 carries droppers 7, each normally supported by a yarn 8. Should failure of yarn occur, the heel 7<a> of the corresponding dropper 7 comes in contact with one of a series, of pegs 17 on a rotating part of the machine and causes the post 2 to be rotated and the support for the corresponding cam 16 to be removed. The needles are thus prevented from rising to feeding position at the place where the failure of yarn occurred, and so retain their loops. This device may be combined with a stop-motion operated by a third arm 19 acting on a displaceable ring 21. On the ring 21 is a cam plate 22, the edge 22<a> of which bears against a stud 23 on a pivoted arm 24. This arm bears against a stud 25 on a slide 26 pivoted to a trip lever 29, the lower end of which normally supports the end 34 of a lever, which is connected by a link 38, shown in cross-section in Fig. 4, with a lever 39. The hub 40 of the lever 39 is internally screw-threaded and works on a threaded portion 41 of a sleeve 42 surrounding the driving shaft 43. The lever 39 is connected by bolts 46 to a collar 47 which is loose on a friction clutch 49. When the end 34 is tripped, the lever 39 is rotated by a spring and, the sleeve 42 being carried by a fixed bearing, the clutch 49 is removed from contact with the driving pulley 51. The stoppage may be effected also by transferring a driving band to a loose pulley, or by electrical means.

Title: A process for the hot-stretching of yarns made from synthetic linear polymers
IPC: D02J1/22
Filed: 1958-07-16
Abstract: A process for the production of potentially smooth and even yarns made from synthetic linear polymers, e.g. polyamides, polyesters, polyethylene and polyacrylonitrile, comprises hot-stretching the yarn, imparting to it during stretching such a low false twist that permanent crimping is avoided, there being no setting of the false twist, and withdrawing the yarn.  The process is said to be especially adapted for hotstretching polyacrylonitrile yarns containing at least 85% of acrylonitrile, by weight, and from 5 to 8% of residual solvent, dimethylformamide, at temperatures of from 145 DEG  to 170 DEG C.  In an example, with the false twist device running at 10,000 r.p.m. and a yarn speed at feed and delivery of 130 and 850 metres p.m. respectively, the twist in the polyacrylonitrile yarn was about 80 and 12 yarns p. metre respectively, the drawing temperature being 150 DEG C.

Abstract: 495,902. Television ; cathode - ray tubes. RADIOAKT.-GES. D. S. LOEWE, Aug. 20, 1937, No. 22852. Convention date. Aug. 21, 1936. [Classes 39 (i) and 40 (iii)] When a scanning ray enters a glass sheet 4 at the edge of a scanned frame 3, the ray is reflected internally through a right-angle by a rear reflecting edge 5 at an angle of 45‹ and is led to a photo-electric cell 8. A condensing lens 7 focuses the ray on the cell. Line and framing signals are produced by glass sheets at the vertical and the horizontal edge of the frame, and both sheets lead the ray to the same cell, Fig. 2 (not shown). The cell 8 and the cell 10, which is behind the scanning frame and produces the image signal, are connected to a common amplifier 11. Alternatively the glass sheets lead the ray to the cell 10. A scene is scanned by projecting the scanning frame on it, Fig. 5 (not shown). When the fluorescent screen of a cathode-ray tube is scanned by an electronic ray and projected on the scene to be transmitted, the glass sheets are on the edges of the screen and are covered with a fluorescent layer, Fig. 6 (not shown).

Abstract: 615,189. Thermionic valve voltmeters. STANDARD TELEPHONES & CABLES, Ltd. Aug. 2, 1946, No. 23101. Convention date, Oct. 30, 1945. [Class 37] A probe for use in conjunction with cathoderay oscillographs, particularly for testing wideband video circuits, comprises a pair of cathode follower valves in tandem, input control means between the probe and the first cathode follower, output circuit means for the second cathode follower, and a phase correction network associated with the second follower. The input to the probe is applied over an input lead 1 which is provided with a probe tip 2 and which by way of a switch 3 applies the input voltageover a coupling condenser 4 and a grid return resistance 5 to the grid 6 of a triode 7. The condenser 4 may be byepassed at 4a when D.C. voltage is applied. The cathode 9 of the triode 7 is directly coupled to the grid 11 of an output cathode follower triode 12 and is connected to an earth lead 14 through a bias and load resistor 15 and a high resistance 16. The plate circuit of the triode 12 includes a phase correction circuit 20 composed of a variable resistor 21 and a capacitance 22. The output of the probe is obtainable from the circuit of the cathode 18 over a shielded coaxial cable 23 and may be applied to an indicator such as a cathode-ray oscillograph over a connection 24. The output circuit of the cathode 18 includes a resistance 25 forming a matching termination impedance for the cable 23 and also a cathode bias and compensating network 26 which consists of biassing resistors 27, 28 and a compensating capacitance 29. The input to the triode 7 may be applied directly by a connection 31 when the switch 3 is in its upper position.
