Title: Hydrocarbon synthesis
IPC: C07C1/04
Filed: 1948-04-01
Abstract: <PICT:0643606/IV (b)/1> In the synthesis of hydrocarbons and oxygenated derivatives from carbon monoxide and hydrogen in the presence of a fluidized bed of iron catalyst, excess heat is removed by a cooling medium maintained at such a temperature that the coefficient of heat transfer, and the temperature differential between the bed and the cooling medium are correlated to give a rate of heat transfer in the region of its maximum.  When the bed of catalyst is at 625-775 DEG  F., the cooling medium should not be maintained below about 600-650 DEG  F., at pressures of 500-800 p.s.i.  For pressures below 200 p.s.i., however, say from 100-200, the cooling medium should be at about 400-450 DEG  F.  Thus within the general range of 100-800 p.s.i., the cooling medium should be within the range 400-650 DEG  F.  For pressures of 200-500 p.s.i., the temperature difference between the bed and cooling medium is preferably not more than about 150 DEG  F.  The reactor 1 may comprise a foraminous member 2 for entry of feed gas into the bed of catalyst C surrounding a bank of cooling tubes 3 through which a cooling medium circulates through lines 23, 24 and boiler drum 20. This medium also circulates through a jacket 6 via lines 25, 26.ALSO:In the synthesis of hydrocarbons and oxygenated derivatives from carbon monoxide and hydrogen in the presence of a fluidized bed of iron catalyst, excess heat is removed by a cooling medium maintained at such a temperature that the coefficient of heat transfer, and the temperature differential between the bed and the cooling medium are correlated to give a rate of heat transfer in the region of its maximum.

Title: Improvements in or relating to toothed gearing
IPC: F16H55/08
Filed: 1926-04-07
Abstract: 266,163. Wildhaber. E. April 7, 1926. Toothed wheels; racks. - Toothed wheel and rack gearing of the spur, bevel, or skew type has single or double helical or like inclined teeth and mating concave and convex tooth profiles of substantially circular arc form in planes normal to the tooth lengths or to the pitch line. As shown in Fig. 1, the working faces of the teeth of one wheel lie entirely outside and those of the other entirely inside the pitch line and the profile centres preferably lie on the pitch circles. The profile radii may vary from onehalf to one and a-half times the normal circumferential pitch of the teeth. Particularly when the gear wheel centres are liable to change, the profile radii may differ in the two wheels. The concave tooth faces would be produced by moving a sphere transversely to the gears with its centre passing along the pitch line at a uniform or varying speed, while the gears are rotated at their gearing speeds. In practice, the sphere is represented by a tool with a circular cutting profile, and the convex teeth are similarly cut; hobbing, milling with disc or end mills, grinding, shaping, or planing may be employed.

Title: Improvements in apparatus for treatment with solvents
IPC: C23G5/04
Filed: 1936-03-30
Abstract: An apparatus for cleaning or degreasing articles consists of a tank divided internally to form a number of wells containing liquid solvent, one well being heated to evaporate solvent which is condensed in a second well and the liquid solvent returned to the first well, a vapour treating zone, and a basket containing the articles adapted to be immersed in any or successively in all of the wells and vapour zone.  A tank 8 excluding air but open upwardly for the introduction and removal of articles, is divided by partitions to form wells 14, 15, storage tank 18, and a hollow dam 16.  The bottoms of the wells and tank slope towards the centre.  The solvent in well 14 is heated by a steam jacket 24, and the vapours fill the upper space which contains a condenser 29.  Condensed solvent falls into the well 15.  Excess solvent flows over the inclined wall 16 into the well 14, <PICT:0462149/III/1> by which floating drops of water are removed from the pure solvent well 15.  At intervals dirty solvent is discharged from well 15 into the tank 18, well 15 is then cleaned, solvent is fed into well 14 and redistilled, after which well 14 is cleaned.  The articles are contained in a basket 32 preferably of polygonal section, suspended by a flexible cable 33 which passes over a pulley 34, attached to a crane 31, to a winding-drum.  The crane is mounted on a carriage 30 which moves over the tank 8 on rails 11. The basket containing the articles is first lowered into the well 14, and the basket moved up and down therein, then into well 15, and finally raised into the vapour zone where solvent vapours condense on the articles.  The basket is then removed and unloaded.  In modifications of the apparatus, (a) the wells 14, 15 and tank 18 are mounted side by side for use with small articles, (b) the well 15 is mounted between well 14 and an additional well containing pure solvent used for a final rinse.  The central well is provided with an upwardly sloped dam, over which solvent flows into the additional well for final rinsing.  This well communicates through a pipe with well 14.  The apparatus may be used for degreasing metal articles before electroplating, in which case the articles are supported in racks formed of "Bakelite" (Registered Trade Mark) insulated material.  Specifications 415,639, 430,704, and 440,732 are referred to.
