Abstract: <PICT:0670914/III/1> <PICT:0670914/III/2> <PICT:0670914/III/3> <PICT:0670914/III/4> A spray of coating material from a gun 2, Fig. 5, is electrically charged by a row of pointed electrodes 111-114 normal to a plane surfaced electrode 6, the opposed electrodes being maintained at a sufficient potential difference to cause ionisation of the atmosphere therebetween.  The electrode 6 may be grounded, Fig. 1, or maintained at a positive or a negative potential.  In the embodiment, the articles to be coated, 16, 18, which may be grounded or maintained at a potential opposite to that of the coating material, are carried on a pair of grounded rails 24.  The articles are hung from insulators 20, and may be connected to a high voltage source by brushes 29, 30 within conduits 42, 43, and conductors 34, 28, Fig. 4.  Blowers 40, Fig. 1, force air through the conduits.  The electric charge on the articles is finally removed on leaving the spraying zone by a grounded chain 58. Alternatively, two clouds of sprayed coating material may be oppositely charged and directed to the outside of articles travelling on a twin conveyer system.

Abstract: 527,427. Electric signalling systems. TECALEMIT. Ltd., and LE CLAIR. C. C. S. March 7, 1939, No. 7454. [Class 40 (i)] An arrangement for indicating rate of movement comprises a pair of contacts 1 which are closed periodically by a cam 5 driven by the moving member, for example, a liquid-flow meter, and which control a relay 7 so that impulses of constant duration are delivered over a circuit including the contacts 1 and normal contacts 8 of the relay. As shown, this circuit supplies current to the heating element 9 of a thermocouple 10, which controls a millivoltmeter 10A. The voltage of the heating current is obtained from a potentiometer 12 in series with a battery 6 and barretter 13. If desired, an electromagnetic counter 16 may be connected in series with the contacts 1. In a modification, the heater 9 heats a resistance forming part of a Wheatstone bridge, the unbalance of which is indicated by a galvanometer.

Title: Improvements in wireless receiving systems

Filed: 1921-03-11
Abstract: 160,140. Ges. f³r Drahtlose Telegraphie. March 13, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic amplifiers and detectors; heterodyne receiving systems; atmospherics, eliminating or limiting.-In thermionic amplifiers for wireless signals, high-frequency and low-frequency amplification are entirely separated. In the arrangement shown in Fig. 2, the similar valves 1, 2 are affected by signals in the circuit I. As a result, an oscillating potential difference is set up at the points a, b at the ends of the resistance R', R<2>. The decrease in the potentials of these points due to the rectifying action of the valves is however the same at anv instant so that the rectifying valve 3 is influenced only by the radiofrequency oscillations. The resistance R<1>, R<2> can be replaced by a choke coil with, if desired, a condenser shunted across each of its halves. In addition, a grid battery may be provided connected through choke coils to the respective grids. In this case, a grid condenser is necessary. In a further example, the resistance R, R<1>, is replaced by an oscillatory circuit tuned to the frequency of the circuit I. A cascade arrangement is described in which the leads from the plates of a pair of valves, connected as shown in Fig. 2, are taken to the grids of a second pair similarly connected. With the connection shown in Fig. 6, rectification and exclusively low-frequency amplification, are given by the valves 3, 4. For heterodyne reception, instead of a separate generating-valve, a back coupling to the circuit I from the anode circuit of the last detector valve, may be used. An arrangement is described, Fig. 8, for combined low- and high-frequency amplification. In a modification, the iron-core transformer P', P' is replaced by an air-core inductance, the condensers associated with the valves 3 being made large enough to pass the lowfrequency pulses. The arrangements described minimize the effects of atmospherics.

Abstract: 307,760. Alloy Welding Processes, Ltd., (Assignees of Soudure Electrique Autogene). March 12, 1928, [Convention date]. Uniting by fusion.-The coating of a metallic arc-welding electrode contains about 5 per cent or less of one or more oxy-acid salts of the kind which are decomposed at a red heat with the evolution of oxygen, so as to lower the starting tension of the arc and render the arc more efficient during operation, particularly with alternating current. The core may consist of a ferrous or non-ferrous metal or alloy and the oxy-acid salt may be a nitrate, chlorate, bromate, or the corresponding per-salts, or a nitrite, chlorite, &c. preferably of the alkali or alkaline earth metals. By adding 3 per cent of potassium nitrate to a coating consisting of 35 per cent of carbonate of lime, 35 per cent of siliceous chalk and 30 per cent of carbonate of magnesia the starting tension is reduced from about 70 volts to 40 volts. Normally from 2 to 3 per cent of the salt is added but if say 10 per cent of powdered metal of the same kind as the core metal, e.g. iron or steel, is added to the coating, 5 per cent of the salt may be used.

[Also in Division G1] In an arrangement for correcting the longitudinal level of railway tracks in which a pair of wires extend forwardly, parallel to the desired position of the track, from a position in a corrected part of the track to a position in the uncorrected portion of the track, the forward ends of the wires are supported on a wheeled chassis and automatic means are provided for adjusting the height of one of the wire supports in dependance on its height with respect to the other support. The height of holding pulley 6, supporting wire 7, is initially adjusted manually by hand wheel 23 to the most advantageous position for correcting several sections of track. Thereafter the height of holding pulley 6<SP>1</SP>, supporting wire 7<SP>1</SP>, with respect to pulley 6 is detected by cross support 5 and a pendulum clinometer 8 which, if a difference exists, controls the operation of a relay 11 to one or other of its energized positions in dependance on which contact 10<SP>1</SP> or 10 is encountered by the pendulum 9. A motor 7, connected to pulley 6<SP>1</SP> via couplings 18, 19, screwed shaft 20<SP>1</SP> and cooperating nut 21 is controlled via the relay contacts to raise or lower the height of the pulley and bring the ends of the wires into the same horizontal plane.
