Abstract: 1,072,747. Metal working hammers. U.S. INDUSTRIES Inc. April 1, 1965 [April 1, 1964], No. 13866/65. Heading B3H. A high energy impact machine has a pair of plates 3, 4 movable together by high pressure gas stored in a chamber 10, the plate 3 having a cylinder 9 containing a sealing piston 16 connected to the other plate 4 and adapted to seal off the chamber 10 from the cylinder, and means 40, 34 for admitting gas from the chamber 10 beneath the piston 16 to lift it from its seating and thus initiate the working stroke. Each plate 3, 4 is slidable in guides 5, 6 and carries co-operating dies 63, 64, Fig. 1 (not shown) for forming a metal workpiece. The chamber 10 is provided within plate 3 by transverse passages 11-14, Figs. 2, 3 (not shown) interconnected at their ends with openings 15 leading into a pair of working cylinders 7, 8 containing hollow pistons and rods 16, 17 connected at 21, Fig. 1 (not shown), with the lower plate 4. Pressure nitrogen from a source 27 is admitted through valves 26, 49 to the chamber 10 and to cylinders 9 above the pistons 16. Charging pistons 60 within the cylinders are then moved downwardly by hydraulic pressure admitted through passages 68, to pressurize the gas in the cylinders and in the chamber 10 and to press the pistons 16 against seatings 18 at the lower ends of the cylinders. The hydraulic pressure is then reduced whereby the charging pistons 60 are retracted by gas pressure in the cylinders 9 acting through the hollow pistons 16. Trigger valve 40 is then opened by a hydraulic actuator 41, Fig. 4 (not shown), to admit high pressure gas from chamber 10 into chambers 19 below the pistons 16, Fig. 6 (not shown). The pistons 16 are thus raised from their seatings and allow the high pressure gas in chamber 10 to act quickly through passages 15 whereby the plates 3, 4 are accelerated towards each other. Recharging is effected by opening the valve 49 which is actuated by a hydraulic motor. The valve 49 may be omitted. The upper plate 3 is retracted by two counterbalance units 56, Fig. 1 (not shown), charged with pressure gas. An electrical control system is described, Figs. 9, 10 (not shown) for the valves 40, 49 and for the supply of gas and hydraulic fluid. A specific example is given of the energy produced by the machine.

Abstract: 477,033. Separating gases by liquefaction. JACKSON, L. MELLERSH-.(Soc. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude) May 18, 1936, No. 14049. [Class 8 (ii)] In the cooling of gases, e.g. air to be separated into its constituents by liquefaction, by passage through a regenerative accumulator in alternation with a cold gas, e.g. the separated nitrogen flowing in the opposite direction, the removal of condensed matter such as carbon dioxide and water from the accumulator is facilitated by cooling the incoming air &c. or nitrogen &c., or both, in the part of the accumulator free of condensate or heating these gases in the other part. Thus, cold or liquefied air or nitrogen may be added to the air or nitrogen in the part free from condensate, or warmer gas in the other part, or gas may be circulated in indirect contact with the gas to be treated, e.g. by thermo-siphonic action, this gas being liquefied in one portion of its flow. To render the temperature difference between the gases suitable in all parts of the apparatus, part of the gas may be withdrawn at one place and reintroduced at another ; or heated or cooled gas, or both, may be introduced at several places ; or the quantity of outgoing gas may be increased in proportion to that of the incoming gas.

Title: Improvements in or relating to the heat treatment of metals and alloys
IPC: C21D1/76
Filed: 1954-05-14
Abstract: 770,906. Furnace atmospheres. GENERAL ELECTRIC CO., Ltd., DOVEY, D. M., and RANDLE, K. C. May 16, 1955 [May 14, 1954], No. 14217/54. Class 51 (2). In the heat treatment of a metal or alloy in a reducing atmosphere, in which the metal or a constituent metal of the alloy is readily oxidizable at the treatment temperature, the atmosphere gas is given a preliminary deoxidizing and drying treatment, and then a small amount of a halide or a hydride capable of reacting at a high temperature to produce either carbon monoxide or a refractory oxide is added either before or after the gas enters the treatment chamber. Among the additives used are chlorides and fluorides of titanium, zirconium, silicon and boron, e.g. the tetrachloride of silicon, titanium or zirconium, and the lower aliphatic hydrocarbons, particularly methane. A typical example is in the bright annealing of an alloy containing: 20 per cent chromium, 20 per cent cobalt, 2 per cent titanium, 1 per cent aluminium, 1 per cent silicon, 1 per cent manganese, 5 per cent iron and balance nickel-at 900-1000‹ C. in an atmosphere of hydrogen flowing through the annealing chamber at 90 litres/hour. A proportion of the hydrogen stream amounting to a flow of 10 litres/hour is bubbled through liquid titanium tetrachloride at 5‹ C., and mixed with the main flow before passing into the annealing chamber. The preliminary deoxidation and drying of the atmosphere gas is carried out in a known manner, e.g. by treating with a de-oxidizing catalyst, such as palladinized asbestos or copper heated to 800‹ C., and then passing through a tower filled with activated alumina. The additive combines with traces of oxygen or water vapour remaining in the atmosphere gas or taken up from the annealing furnace walls.
