[Also in Group II] A process for producing thermo-electric elements consisting of a ternary alloy system Zn x Cd 1-x Sb (where x lies between 0 and 1 inclusive) comprises melting the system and then subjecting it to a temperature at which the resistance-temperature curve exhibits an anomaly (i.e. a sudden change in slope). The temperature of the molten material may be brought down to the treatment temperature or the material may be cooled and then raised to this temperature. The treatment temperature, as shown on Fig. 1, is 468  C. for a value of x=0.7, 482 C. for x=0.94 and 505 C. for the limiting value x=1. The heat treatment may be continued for 24 hours. The material may be doped with lithium, sodium or potassium applied as compounds, e.g. alkali halides or metals, or with elements of the VIth Group, such as S, Se and/or Te to act as donors. Each limb of a thermo-couple may be doped differently along its length or be composed of different materials, reference being made to a known arrangement of this type comprising Bi 2 Te 3  and an A III B V  compound.

Abstract: 1457361 Making self-tapping screws; thread rolling; electric arc deposition LITTON INDUSTRIES Inc 6 March 1974 [23 April 1973] 10152/74 Headings B3N B3M and B3R and B3A In a method of producing self-tapping screws, which have surface areas hardened by deposition of a harder material using an "electrodedeposition" technique, a preferably vibrated electrode made from the hard material is brought into contact with the screw surface areas and an arc is formed between them whereby the hard material is transferred. Typical hard materials are the carbides of tungsten and titanium and the method is particularly suitable for lowcarbon steel screws of aluminium and other non-ferrous metal screws. One apparatus for carrying out the method comprises, in Fig. 3, thread rolling dies 40, 42 modified by having guide element 60 one one of them which carries at least one electrode 62 and the screw 44 is rolled along the element after the thread is formed. In Fig. 4, both dies 50, 54 have guide elements and also extra grooved ribs at the lower edges to form a tapered pilot end on the screw. Triggering switch or sensor 70 may be provided for switching on the power to the electrodes. Where the screw has a tapered pilot end, the electrode may be complementarily formed with an oblique end (Fig. 6, not shown) The electrode may also be of elongated form extending in the direction of rolling (Fig. 5, not shown). In a third arrangement, Fig. 7 the electrode 90 is provided below the screw. The apparatus may include a combination of the electrode 90 and one of the other types. The screw formed by the above apparatuses has material deposited only on the crest or crests 24 of the thread or threads 22, Fig. 2, so that the groove walls and the core of the screw remain tough and resilient to withstand shock. The whole length of the thread may be so treated or only discrete areas 26 as shown in Fig. 1. it is preferred that only the pilot end 14 of the screw be treated. The screw in Fig. 1 also has an intermediate portion with a ribbed screw thread 23 which is resiliently bendable and protrudes outside the boundary of the normal screw thread flank to provide, in use, a self-locking action of the screw. The screw may be threadcutting with an axial groove thread forming and/or self-drilling.

Abstract: 642,018. Starting. DAVEY, PAXMAN & CO., Ltd., and POWELL, J. A. BENNETT-. April 12, 1948, No. 10156. [Class 7 (v] [Also in Group XXXIV] A single air compressor b, charging a high pressure reservoir g used for starting the engine d and a low pressure reservoir k used for operating the brakes, is driven at starting by an auxiliary engine a, e.g. a small diesel engine coupled thereto by a hand or automatically operated clutch. It delivers through a pipe e and non-return valve f into the reservoir g, the reservoir k being also connected to' the pipe e through a non-return valve o and a spring loaded pressure controlled valve s which is held closed by the pressure in the pipe e until the reservoir g is fully charged, when the pressure therein acting through a pipe m on a piston q opens the valve s to allow the compressor b to deliver at lower pressure into the reservoir k. An unloading valve u connects the delivery pipe e to atmosphere when the reservoir k is fully charged, and if the pressure in the reservoir g drops, the valve s closes to cause the compressor b to recharge it. When the engine d is started it drives the compressor through a belt c, the engine a being uncoupled and stopped. If the pressure in the reservoir k drops, a valve i may be opened to re-charge it from the reservoir g.

Title: Improvements in ionic relays
IPC: H04L25/24
Filed: 1918-06-21
Abstract: 148,582. Eccles, W. H., and Jordan, F. W. June 21, 1918. Thermionic relays.-A thermionic relay or amplifying-apparatus for telegraphic or telephonic work comprises a pair or an even number of ionic valves connected in sequence by resistances with a return connexion so that the magnified potential difference along a resistance in the anode circuit of the last valve is communicated to the control electrode of the first valve to obtain amplification of the initial stimulus by retroaction. Fig. 1 shows a method of applying the principle using two three-electrode valves. When the electrical stimulus which it is desired to detect is impressed upon the grid circuit S of the first valve, the grid G<1> becomes more positive (for example) in potential relative to its filament. This causes an increase in the plate current of the first valve and consequently an increase in the potential difference between the ends of the resistance R'. The increased potential difference is transferred to the grid of the second valve so that it becomes more negative relative to its filament. Consequently the plate current of the second valve decreases, and the potential difference between the ends of the resistance R<2> in its plate circuit decreases also. This decrease is now transferred to the grid circuit of the first valve in such a manner as to makes its grid G<1> more positive relative to the filament. If, by adjustment, the resistances R<1>, R<2>, and the voltage factors E<1>, E<2>, are arranged so that the working condition of the set is one of instability, retroaction will continue until the plate current of the first tube reaches its maximum and that of the second tube its minimum value, and in order to restore the initial conditions it is necessary to interrupt the interaction of the valves. If, on the other hand, the set is adjusted for stable working, the electrical changes persist only while the outside stimulus is applied. In the modification shown in Fig. 2, a stimulus applied to the grid G<1> produces a change in potential along the resistance R'. This change of potential is of opposite sign from that initially imposed on the grid G', and being communicated to grid G<2> gives rise to a potential drop along resistance R<2>. This potential drop is of the same sign as the initial applied stumulus, and is transferred to grid G<1> to give a retroactive effect. An instrument I may be connected in either of the anodecircuits to indicate changes in current or voltage.. The batteries e<1>, e<2> in the grid circuits are introduced for the purpose of adjusting the grid voltages to suitable values. Any even number of valves may be used in cascade or independently grouped in pairs and combined in any suitable manner. In the typical two-tube arrangement the two valves may be replaced by a single duplexvalve.
