Title: Improvements in apparatus for responding only to a predetermined series of electric signals
IPC: H04L15/26
Filed: 1936-01-01
Abstract: 468,230. Electric signalling systems. WATANABE, Y. Jan. 1, 1936, No. 43. Convention date, June 2, 1935. [Class 40 (i)] Apparatus responding only to particular electric signals comprises a step-by-step member moved at each mark of correct length, the member being reset by a mark or a space of incorrect duration. Relay A responds to the received pulses and the circuits from magnet D and relays M1, M2 and M3 are completed. Magnet D lifts member c so that the stepping and holding pawls a and b move into engagement with the rack e. Relays M1, M2 and M3 operate with delays of 1, 3 and 5 seconds respectively, a mark of correct length being of between 3 and 5 seconds duration. If the pulse lasts over 3 seconds, relays M1 and M2 pull up so that magnet E is operated to step rack e and relay B operates and locks. When the mark ceases, relay A falls away and relay C operates. The space relay S is also energized but this relay has an operating lag of 2 seconds. Relays B and C and magnet D are held up during the space period but relays M1-M3 are de-energized and magnet E releases. At the termination of the space, relay A again pulls up, completing the circuits of relays M1-M3, but relays B, C and S remain energized. When the mark has lasted 1 second, relay M1 pulls up and between the opening of contacts 14 and the closing of contacts 15 relay B is released so that relays C and S are also reset. When the mark has lasted 3 seconds, relay M2 again pulls up and magnet E is energized to step the rack bar e. This cycle is repeated on a correct signal until the bar e closes contacts 19. Relay F energizes and locks and the alarm m is operated. If a mark is too long, relay M3 is energized to release D and reset the bar e whilst if the mark is short, relay M2 does not pull up so that relay B is not energized and magnet D is released. If the space period exceeds 2 seconds, the relay S will operate to release relays B and C and so release magnet D to reset the rack bar.

Filed: 1926-01-02
Abstract: 271,530. Chopra, N., D., and Bullen, F. J. Jan. 2, 1926. Modifying physical characters of metals.- Rolled steel members, e.g. railway rails, once or oftener between successive rollings or other operations, are cooled to a temperature below the lowest Ar change-point of the steel, and subsequently re-heated, the steel being subjected to the re-heating, or both the re-heating and cooling, in the presence of an alkaline-earth oxide, such as lime and a non-carburizing carbonaceous material. Following this, there may be a final heat treatment such as that described in Specification 271,529. The quantity of alkaline-earth oxide may be from ten to fifty per cent of the total weight of the oxide and the carbonaceous material, and the carbonaceous material may be such that the free carbon present is from four to twenty per cent of this total. The heat treatment may also be effected in the presence of infusible oxidizable material, e.g. steel shavings, spread in the furnace about the member under treatment, or may be effected in a cage or like structure of iron plates, bars, &c. The treatment gives good effects with steel containing a small proportion, for example about one-half per cent, of a metallic element, such as nickel or cobalt. which tends to depress the change-points, and with chrome-steel, and with chrome-steel containing nickel and cobalt. Specification 271,606 is referred to.

Abstract: 576,274. Construction of links. BROWN TRACTORS, Ltd., D., SMITH, A. E., MEADOWCROFT, F., and MERRITT, H. E. Jan. 7, 1944, No. 307. [Class 80 (iii)] [Also in Group XXXII] A compression member, for use in linkage connecting an implement to a tractor, and designed to yield in case of an excessive draft load, is characterised in that when the overload reaches a predetermined amount, the parts comprising the member yield rapidly and thus shorten with mechanical "snap" action. The compression member, Fig. 1, comprises a rod b connected by a screwed sleeve h to the stem i of a ball joint and is retained from telescoping into a sleeve a by balls c. The balls engage a recess b' in the rod and are retained therein by the pressure of an adjustable spring f acting on a slidable collar e provided with inclined faces e'. A Bowden wire is connected to the collar e and the casing is anchored to the key b<3>. When the trailing vehicle strikes an obstruction, the balls are forced outwardly by the rod b to raise the collar e against the spring pressure, thereby allowing the rod to slide into the sleeve a. This movement is transmitted to the Bowden wire to release the tractor clutch or cut off the ignition. In a modification, the sleeve a may be extended through the collar e and be provided with orifices through which the balls may slide.

Tanks 22 are firstly supplied with gas, e.g. CO 2  under pressure, and then fed with a liquidgas mixture at a higher pressure, and means are provided to receive the gas therefrom during the feeding of the mixture. The gas and liquidgas mixture are contained in a reservoir 10 supplied with gas through a line 18 and valve 20, and with liquid through a line 16. The tanks are supplied with liquid-gas mixture through a manifold 26 and lines 72, and with gas via a fitting 40, a regulator valve 38, line 36, valve 46, manifold 34 and lines 66. A regulator valve 50 with a vent tube 60 to atmosphere to coupled to the manifold 34, and a three-way valve 58 is located, as shown, in the manifold. The valves 38 and 50 are of the diaphragm type with adjusting screws 52, 54 respectively and are biased in accordance with the instantaneous pressure in the reservoir 10 so that they operate at differential pressures which are constant relative the reservoir pressure. Valve 38 admits gas to the manifold when the pressure therein falls too low, and the valve 50 releases gas therefrom when the pressure is too high. The gas manifold pressure may be 10-15 1b. per square inch less than the reservoir pressure, and the valve 50 may be adjusted to release at 2-3 1b. per square inch in excess of the pressure at which valve 38 closes. Each tank is fed with gas through a check valve 68 of the floating ball type which cuts off the supply to the tank when the pressure therein is equalized with that in the manifold 34. The liquid-gas mixture is then supplied and the counterpressure gas is returned to the manifold to be fed either to a further tank or to be vented through the valve 50. The valve 68 prevents liquid flowing to the gas manifold when the tank is full.
