Title: Improvements in brick making machines
IPC: B28B13/02
Filed: 1926-05-25
Abstract: 273,863. Whittaker & Co., Ltd., C., and Whittaker, N. May 25, 1926. Combined moulding and re-pressing machines; stationary-mould machines.-In a brick-making machine the semi-plastic material is formed into a shaped clot on a reciprocating slide by a reciprocating ram before it is fed to the mould by the slide which in one movement allows the clot to fall in front thereof and in the reverse movement feeds it to the mould. A slide A and a ram G are reciprocated by a lever D from a cam E on a shaft e actuating the moulding plungers F, F<1>. When the ram and slide are drawn back, material from the hopper H falls on to the slide in front of the ram which, on the forward stroke and in conjunction with a plunger J, form the material into a clot d against a fixed plate G', excess material passing through a channel l to the hopper. On the return stroke, the clot falls on to the table B in front of the slide A which on its next forward movement advances it over the mould M to be moulded by the plungers F, F<1>. The plunger J is lifted by a counterweighted lever K and depressed by a bracket f carried by the plunger F. This plunger and the ram G are heated to prevent the material from sticking.

Abstract: 1,207,924. Urea. STAMICARBON N.V. 13 March, 1969 [16 March, 1968], No. 13347/69. Heading C2C. Urea is produced from ammonia and carbon dioxide in a combined urea-synthesis/ammoniasynthesis process in which (a) "synthesis gas" comprising hydrogen and carbon dioxide with carbon monoxide as contaminant and optionally also containing nitrogen is passed to an ammonium - carbamate - forming zone of a urea - synthesis zone, (b) oxygen is mixed with the synthesis gas in an amount based on the amount of carbon monoxide therein, (c) carbon monoxide in the effluent gas from the ammonium-carbamate - forming zone is oxidized to carbon dioxide, (d) carbon-dioxide is removed from the effluent gas with an ammoniacal solution to form an ammonium carbonate solution which is recycled to the ammonium - carbamate - forming zone, and (e) the effluent gas freed from carbon dioxide is passed to an ammoniasynthesis zone and the ammonia so produced is passed to the ammonium - carbamate - forming zone. The solution produced in the urea synthesis zone may be stripped to remove ammonium carbamate in two stripping stages at substantially equal elevated pressures, the stripping gas in the first stage being the above-mentioned synthesis gas and in the second stage being comprised of the gas streams used for the ammonia synthesis being substantially free from ammonia and carbon dioxide (see Specification 1,207,923.

IPC: D06F1/00
Filed: 1918-08-16
Abstract: 120,708. Patterson, T. J. Aug. 16, 1918. Washing-boards. - Comprises a special construction of soap-holder for fitting to wash-boards of the kind provided with soap-holders for automatically soaping the clothes during the rubbing operation. The board is provided with an opening near the top covered by parallel wires 5. The soap is placed in the opening and is pressed upwards against the wires by a plate 18 mounted on the spring-actuated U-shaped frame 10. The frame is mounted on an axle carried in eyes fixed on the back of the board. The spring is mounted on the axle and one end 17 of it bears against one of the arms of the frame. In a modified construction, shown in Fig. 5, which is adapted for the ready removal of the soap, a corrugated plate 20 is used which is pivoted to the U-shaped frame. To remove the soap, the frame is drawn rearwardly until the plate 20 abuts against a fixed rod 29. Further movement of the frame then causes the plate to rotate until one of the pivot eyes abuts against a fixed stop 25 on the horizontal arm of the U-shaped frame. In this position the block of soap is at right-angles to the position shown in Fig. 5 and may be readily detached from the plate 20.

Title: A method of and apparatus for recovering a high calorific converter or like fining gas without hazard
IPC: C21C5/38
Filed: 1962-04-09
Abstract: A method of recovering high calorific gases' e.g. from a converter or from a cyanide process' comprises exhausting the unburnt gas through a hood to a flue which contains an oxygen-binding material, e.g. coke, which burns off any oxygen which may have been introduced, intentionally or not, into the gases, the coke-filled flue thus acting as a gas producer.  Risk of explosion is thus diminished. Between blows of the converter, the coke bed may be adapted to act as an induced draught gas producer, liquid slag from which is tapped off. Alternatively, a fan may be arranged automatically to start to draw gas from the converter at the beginning of each blow, and the fan may be controlled in accordance with the quantity of gas given off by the converter.  Where the producer operates only during blows, the temperature of the coke may be maintained by introducing sufficient air or oxygen to support combustion.  Steam, e.g. that normally used to seal the hood, may be introduced into the coke to promote the water gas reaction, or water may be sprayed into the converter gas. Two gas producers arranged in parallel may be employed alternately.
