Filed: 1926-04-30
Abstract: 252,146. Lentz, H. May 18, 1925, [Convention date]. Stoppers with valves. - Collapsable tubes &c. are formed with a cylindrical neck 2 provided with lateral outlet apertures 10 which communicate with a space 11 formed by the neck and a sliding cap 5 seated thereon. A spring 12 presses down the cap causing its lower edge 6 to engage packing on a shoulder 7 on the neck whilst the edge 8 of an aperture in its top engages a bulged portion 9 on the end of the neck, the arrangement forming a kind of double seated valve with an interposed piston slide. The spring 12 comprises a rod which is secured at its ends in projections on the cap and passes through the aperture 10 to engage the closed end 14 of the neck. The end is formed with two opposite grooves 15 adapted normally to compel the spring to lie in their axis and engage only with the apex 14<1> of the end 14, but adapted also to allow the spring to engage the end 14 by the plain portions at the sides of the grooves to lock the cap when it is rotated in the closed position. The device may be applied to a collapsable tube having an ordinary screwthreaded neck.

Title: Method of manufacturing a concrete pipe by centrifugal moulding
IPC: B28B7/38
Filed: 1976-03-22
Abstract: 1498590 Lining centrifugal pipe moulds KURIMOTO HUME PIPE Ltd 22 March 1976 [20 March 1975 (4)] 11497/76 Heading B5A A mould 1 is provided with an internal solidified layer 3 of a stripping agent, and is then rotated with its axis horizontal to centrigugally mould a concrete pipe from a slurry. Heat is applied to partially cure the concrete while still in the mould and to melt the stripping agent, whereafter the pipe is removed from the mould and curing completed using steam. The stripping agent comprises paraffin, wax, asphalt, pitch or a mixture of these, melting at 45-55‹ C. and is applied to the mould by liquid spraying, or rotating the mould while hot-blasting a contained powder. A steel reinforcing cage is inserted in the cylindrical or tapered one-piece cast iron mould 1, which is provided with metal ends 4. Rotation is effected via tyres 2 by a driving roll as slurry is introduced. When the concrete is stiff rotation is stopped, and after 1 hour standing at room temperature the mould and pipe are placed in hot water or a steam chamber at 65‹ C. When partially cured and the stripping agent has melted, the pipe is pushed from the mould and further steam cured. Stripping agent remaining on the pipe is thus reclaimed and reapplied to the mould. The mould may define a socketed pipe.

Abstract: 314,163. Ewan, T., and Imperial Chemical Industries, Ltd. April 19, 1928. Carbon; hydrogen.-Carbon is obtained as a bye-product in the production of hydrogen by treating water gas or the like with steam, removing the carbon dioxide and the sulphur compounds, e.g. by washing under pressure with water or ammonia liquor, washing the compressed gas with ammoniacal cuprous solution, releasing the pressure on and heating the cuprous solution to obtain carbon monoxide which is substantially free from catalyst poisons and is then catalytically decomposed in known manner to give carbon. A substantially halogen-free ammoniacal cuprous solution containing for example cuprous formate, acetate or carbonate, is preferably employed. Specification 252,152 is referred to.

Abstract: 565,439. Ingot moulds. FERRO ENGINEERING CO. July 21, 1943, No. 11875. Convention date, July 30, 1942. [Class 83 (i)] An upwardly-tapered hot top 11, lined with refractory material 15, has, in the inner face of said lining, a wedge-shaped cavity 22 with its big end up. This cavity may finish short of the top of a lower refractory block 16, Fig. 6, or extend through the top thereof, Fig. 1, or into an upper block 32, Fig. 5. There may be two opposed cavities to produce, on the sinkhead, vertical faces for engagement by the bits of a handling crane. The cavities 22 may, however, be filled with slurry s and one or more furrows 26 be formed therein with a blunt tool or a finger of the operator. When the hot top is stripped from the ingot, the baked slurry will give way beneath the beads 38, Fig. 6, thus formed on the sinkhead and the faces 24 are not damaged. If the faces 24 are inclined upwardly and outwardly, as shown in Fig. 6, the inclination must be so slight that contraction of the sinkhead 39 on cooling will move the bead 38 inwardly beyond the vertical plane 40 through the bottom edge of the wedgeshaped cavity 22.

Abstract: 845,445. Converting. BRITISH THOMSON HOUSTON CO. Ltd. May 13, 1958 [April 12, 1957], No. 12066/57. Class 38 (2). Undirectional pulses are derived from a pulse generator supplying pulses of alternately opposite polarity by a circuit comprising a pair of oppositely polarized pulsactors 1, 2, i.e. saturable chokes whose cores exhibit square hysteresis loops and which are biased by D.C. windings into opposite states of saturation, in parallel paths. As shown in Fig. 1 the pulsactors are connected to opposite ends of a transformer primary winding 3 whose centre tap is connected to a pulse generator terminal. The pulsactors each present a high impedance to opposite pulses so that unidirectional pulses are produced in the winding 3 and hence in the secondary winding of the transformer. In a first alternative arrangement a bridge-connected arrangement of four pulsactors is utilized, and in a second altertive arrangement the pulsactors are in the secondary circuit of the transformer. Specifications 666,574 and 666,575 are referred to.
