Patent GB-206132-A (GB)
IPC: C04B5/00
Filed: 1923-10-11
Abstract: 206,132. Soc. Anon. des Chaux et Ciments de Lafarge et du Teil, (Assignees of Maguet, M.). Oct. 26, 1922, [Convention date]. Granulating.-Molten slag is granulated by the action of a gaseous or liquid fluid under pressure by causing inclined converging straight jets of the fluid to play uniformly on a stream of molten slag which falls for a certain distance through the atmosphere before it is acted upon by the said jets, the action of the jets being in the direction of flow of the slag from the periphery to the centre and the axis of the flow of the stream coinciding with the axis of convergence of the jets. In one form, Fig. 2, the jets of fluid from the orifices b, which are arranged uniformly and at the same distance from the axis of the member a and uniformly inclined to the axis, converge at a point c in the slag jet h. The orifices b may be provided with screwed nozzles, and may be replaced by an annular aperture. In another form, Fig. 8, a member f consisting of two oppositely directed truncated cones may be provided as shown.

Title: Shock absorber valve

Filed: 1974-06-07
Abstract: 1453004 Shock absorber base valves; valves MONROE BELGIUM NV 7 June 1974 [14 June 1973] 25426/74 Headings F2S and F2V A shock absorber base valve comprises a body 60, a first annular valve disc 80 adjacent one side of the body and having a peripheral portion which deforms to allow flow in one direction, and, for controlling flow in the other direction, a second annular valve disc 118 adjacent the other side of the body seating against the body and against an axially movable relief valve member 106 biased by two spring elements 122, 130, the second valve disc 118 moving off its seat 100 against the bias of the spring 122 at a certain pressure, and, at a higher pressure, the disc and the relief valve member moving away together against the bias of both springs to increase the flow path. On compression movements, when the pressure in the cylinder is low, liquid flows from the cylinder through a bore 90 and a slot 92, through an opening 104 in an orifice disc 102 and into a recess 94, causing the valve disc 118 to move downwardly against the bias of spring 122 and allow flow through to the reservoir via slots 72. At higher compression speeds, the pressure of the liquid flowing through the bore 90 and the slot 92 causes the relief valve member 106 to move away from the body against spring bias, carrying the valve disc 118 down with it. The valve disc 80, which controls flow from the reservoir to the cylinder, may be biased closed by a star-shaped spring (not shown).

Title: Improvements in the production of gassous mixtures of hydrogen and nitrogen
Inventor: GRISENTHWAITE ARTHUR TURNER
IPC: C01B3/02
Filed: 1950-10-30
Abstract: <PICT:0685962/III/1> A gas, especially for ammonia synthesis, which has a very low methane content and consists mainly of hydrogen and nitrogen, is made from the gases produced by a two-stage gasification of a volatile matter containing fuel such as coal, peat or wood, with air.  The gas produced in the first stage, consisting of a mixture of distillation gases and producer gas, is evolved from the upper zone of a producer 10 and is used as a reducing gas in a steam-iron hydrogen generating plant 11, the gas reducing iron oxide which then has steam passed through it to yield a gas rich in hydrogen and free from methane or nitrogen.  The second stage gas consists of "true" producer gas and is withdrawn from the lower part of the producer and passed to a plant 12 where its carbon monoxide reacts with steam to give a gas containing carbon dioxide, hydrogen and nitrogen.  After removal of the carbon dioxide, the gas is mixed with the gas rich in hydrogen in the desired proportions.  Alternatively, if the fuel is suitable, a mixed water gas and distillation gas can be made for use in the plant 11, the nitrogen containing gas being obtained in the "blow" period, or in the "run" period by using a mixture of air and steam.
