Casting-machines; metal-pouring. - A centrifugal casting-machine for pipes comprises a mould casing 14 supported by rolls 24 on rails 25 and traversed by an hydraulic ram 20. Tappets 21, 22 engage a valve 42 to give a slow motion at the ends of the stroke. A pouring nozzle 6 discharging at 26 is detachably secured to a swivel member counterbalanced at 13 and supporting a funnel 1 by a variable number of distance-pieces to control the head employed. A bottom-pour stop-rod 2 is provided seating on the lining of the nozzle which consists of a series of different refractory layers 30, Fig. 8, such as fireclay, graphite, and asbestos. The mould 15 is supported on rollers in the casing and is driven from an electric motor through a change-speed mechanism. The mould is first moved over the nozzle and the rod 2 is raised and the mould is then fed to the right in Fig. 1, thus depositing the metal spirally in the mould. The nozzle may be swung aside laterally for repair or replacement and may be preliminarily heated. The nozzle and mandrel supports may be traversed instead of the mould. Moulds.-The mould is lined with a spiral 17 and gases produced are exhausted from the casing 14. Water is supplied through the ram 20 and bracket 23 to pipes delivering jets against the mould. Coating and lining moulds.-The nozzle 6 may be replaced by a device for spraying a coating on to the mould, for example to soften the casting. Cores.-The socket end of the pipe is formed by a collapsable core 18 composed of segments 37, Fig. 6, connected by springs 38 that collapse the core when soft-wood spacers 45 have charred away. Plates 36 cover the joints and support the spacers. Castings, extracting; casting processes. - The cast pipe is removed from the mould, as soon as set, by a mandrel 9 which extends into the mould when the mould is clear of the nozzle. The mandrel is balanced at 12, can swivel on rollers 10 to facilitate removal of the pipe, and is raised by a ram 8 to engage the pipe to effect withdrawal from the mould, the core being first removed by mechanical means.

Patent GB-821728-A (GB)
Title: Improvements in methods of chromizing metallic powders
IPC: C23C10/42
Filed: 1957-03-12
Abstract: A powder, the grains of which have as a principal component a metal of the group iron, nickel, cobalt, molybdenum, tungsten, and alloys of at least two of said metals, is chromized by heating in a reducing or neutral atmosphere an intimate mixture of said powder with a powder consisting at least partly of chromium and evolving vapours of a chromium halide in said mixture.  The powder to be chromized may contain minor ingredients such as aluminium and chromium; the atmosphere may be hydrogen, ammonia or a mixture of hydrogen and nitrogen; and the chromizing operation is effected so that sintering of the powder mixture is avoided either by heating at a temperature below the sintering temperature or by including a diluting powder such as magnesia, lime or graphite in the mixture.  The chromium powder in the mixture may be added as such or may be formed in situ by reduction of an oxygen compound of chromium, e.g. the oxide, carbonate or oxalate, with an alkali or alkaline earth metal.  The chromium halide may be obtained directly by addition as such to the mixture, or indirectly by the action of another halide on chromium; when the halide is not a fluoride, the powder to be chromized is oxidized before chromizing by the addition of ammonium or magnesium carbonate to the mixture.  In modifications, (a) mixed layers are produced on the powder by adding, e.g. silicon, aluminium or zirconium to the mixture, (b) a chromium carbide layer may be produced by carburizing the powder before it is chromized, (c) the chromized powder may be nitrided by heating in ammonia, and (d) the chromized powder may be oxidized by heating in hydrogen containing oxygen or water vapour.

Title: Improvements in pneumatic tyres
IPC: A63H33/16
Filed: 1954-03-22
Abstract: A composition that is to be injected into a mould to form part of a pneumatic tyre comprises a polyester or polyesteramide, a di-isocyanate and a cross-linking agent, e.g. water, polyhydric alcohol, polyamine or aminoalcohol.  The relative proportions of the three constituents may be 1 : 2 : 1.  First the water &c. may be mixed with the polyester, the di-isocyanate being then added, or the three constituents may be fed separately to a mixing and into the mould.  The mixing temperature may be below 60 DEG  C. but the injecting temperature greater than 60 DEG  C.  In an example adipic acid is esterified with a mixture of ethylene and propylene glycols to give a polyester, water is dissolved in some of this polyester, carbon black is mixed with another lot of the polyester, and the two lots of polyester are mixed together. Molten p,p1-diphenylmethane di-isocyanate is added to a third lot of the polyester and this mixture is mixed with the mixture of the first two lots of polyester. To ensure solution of evolved carbon dioxide in the composition a pressure of, say, 150 lb. p.s.i. may be applied to the composition during moulding.
