Abstract: 784,101. Annealing steel wire. CROSS MANUFACTURING CO. (1938), Ltd. March 7, 1956 [May 17, 1955], No. 14176/55. Class 72  A method of softening steel wire comprises leading the wire through a tube to which coal gas is fed and heating the tube so that it is hotter at the end at which the wire enters than at the end at which it leaves. As shown, a tube 2 is connected to a supply of coal gas from a main 6 which supplies high temperature burners 8 and low temperature burners 9 which heat the tube. The wire 1 is passed through the tube in the same direction as the flow of gas and is quenched immediately it emerges therefrom by an oil spray 10. The tube may be sloped upwardly from the end at which the wire enters, as shown, or it may be horizontal and the number of burners in the low temperature series 9 reduced in order that the tube may be cooler at the discharge end for the wire. The coal gas may be ignited where it discharges from the tube at the entry and discharge points of the wire. The Provisional Specification also refers to the use of a gas other than coal' gas.

Title: Condenser with electrodes capable of burning out
IPC: H01G4/015
Filed: 1954-05-14
Abstract: 760,748. Capacitors. STANDARD TELEPHONES & CABLES, Ltd. May 14, 1954 [May 22, 1953], No. 14189/54. Class 37. In a self-healing capacitor comprising a dielectric strip coated with a thin metallic layer which is wound spirally or is folded in zig-zag form, the tendency for damage due to overheating to occur at the terminals when a momentary short circuit occurs within the capacitor is reduced by arranging a longitudinally extending resistance portion within the metallic layer close to the terminal connections thereof. The resistance portion may comprise a thinning of the metallic layer or a strip of a different metal. Fig. 2a shows the metallized dielectric strip 1, which may be made of paper or a plastic material. Portions 2 of the end layer which is deposited on the capacitor after winding or folding and whereby contact is made between the metallized layer and the corresponding lead are shown. The portions 2 do not extend continuously along the edge of the layer so that after the strip has been wound or folded it may be suitably impregnated with a liquid medium. The metallized layer comprises a resistance portion 4 wherein the thickness of the metal is reduced. The effect of this resistance portion is that if a fault should develop as shown at 3, so that a current flow through the dielectric at this point and heals the fault by vaporizing the adjacent metal on the strip 1, the momentary heavy current which flows does not pass wholly to the nearer ones of the portions 2, but is distributed among a greater number of such portions so that the tendency for the metal to vaporize at these terminal points does not occur. Also the value of the current is somewhat limited. Fig. 4 shows an alternative form of the metallized strip; other forms comprising a plurality of continuous resistive strips and one wherein the resistive strips form a honeycomb pattern are also described.

Abstract: 762,279. Guided skip hoists. STOTHERT & PITT, Ltd. May 7, 1954 [May 22, 1953; Oct. 29, 1953], Nos. 14546/53 and 29942/53. Class 78 (3). [Also in Group XVIII] A load skip can be drawn up an inclined rail for emptying, and when in its lowest or loading position, its weight is measured by a fluid operated ram whose pressure can be relieved so that it is clear of the skip. A skip S has two pairs of wheels 18, 19 moving on a channelled ramp 15, and is supported on an hydraulic ram W actuated by a hand-pump P until the required load, indicated by the hydraulic pressure gauge, is reached. It is then hoisted by ropes L until the wheels 19 enter pockets 20 when the skip pivots about the pockets and empties e.g. into a mixing drum D. The pump P is operated by handle H and is connected to the ram W over a two-position three-way valve V. When valve V is as shown in Fig. 3, the pressures on each side of the piston 26 are equalized, but when the valve is as shown in Fig. 4 the piston 26 rises to lift the skip, the pressure being read on dial G. As the skip is pulled up the ramp, a roller 53 engages handle B and puts valve V into the position of Fig. 3, so that the ram drops to its lowest position and will not be damaged if the skip falls back. A rubber block 45 prevents damage should the piston drop too quickly. A spring relief valve 46 reduces risk of damage due to hydraulic shock. The ramp 15 may fold up. It comprises lower portions 2 pivoted at 3 to swing up. In operation the portions 2 are locked to the machine by nuts 7, and when travelling brackets 11 and nuts 7 hold the ramp up. Jacks 13 provide firm anchorage.
