Filed: 1928-06-08
Abstract: 294,100. Epner, C. July 16, 1927, [Convention date]. Acyclic hydrocarbons. - Liquid hydrocarbons, suitable as power fuels, are obtained by subjecting gases containing hydrocarbons to the action of dark or silent electric discharges, preferably of high tension and periodicity. The reaction is carried out at increased temperature so that the products are removed in vapour form and may be separated by cooling, by absorption in active carbon or in wash oils. The unsaturated products may be hydrogenated, preferably by passing the vaporous products from the reaction which already contain hydrogen over a heated catalyst. The gases may be led through a Siemens tube and subjected to an electric discharge of 500- 10000 cycles at 1000-25000 volts. The gas may be preheated or the electrode liquid may be heated, and the hydrogenation apparatus may be heated by being placed in the centre of a circle of discharge tubes.

Title: Internal combustion engine having an exhaust gas recirculation system
IPC: F02M25/07
Filed: 1971-05-25
Abstract: 1299310 Recycling exhaust gas FORD MOTOR CO Ltd 25 May 1971 [27 July 1970] 16827/71 Heading F1B An I. C. engine has a recirculating valve in a passage between an exhaust means and an intake means, the valve member being controlled by a cam in a housing and a vacuum motor, attached to the cam, responding to intake manifold pressure to move the cam along one axis and linkage means connected with a throttle in the engine intake for rotating the cam about the axis in response to the position of the throttle means. Exhaust gas from exhaust pipe 32 passes through a chamber 28, which is traversed by conduits 34, 36 carrying engine coolant, and through an orifice 44, controlled by a valve 48, into a chamber 26. Engine crank-case gases also enter chamber 26 and the gases pass via passage 52 into a carburetter 12 downstream of throttle valve 18. At starting and warm-up recirculation is ineffective in reducing pollution so that, under these conditions a temperature responsive valve 68 connects vacuum chamber 66 to atmosphere permitting spring 70 to position cam 60 to close valve 48. At higher temperatures valve 68 connects chamber 66 to the intake manifold 10 to position cam 60 as shown. During idling the closed throttle 18 rotates cam 60 to close valve 48. At small accelerations the throttle movement and rising manifold pressure moves the cam to a position where valve 48 opens to provide some recirculation and at greater  accelerations the rising manifold pressure progressively reduces the recirculation.

Title: Improved appliances for playing a race game
IPC: A63F3/00
Filed: 1932-06-16
Abstract: 404,614. Board games. MOSSE, C. B., Cannanore, Mysore, India. June 16, 1932, No. 17094. [Class 132 (ii).] A race game apparatus comprises an inverted box c covered with a cloth b on which a plurality of parallel tracks are marked, obstacles i and a rail e. Suitably differentiated models, for example, horses d, corresponding to the various competitors, are advanced in turn along respective tracks according to the throw of a die manipulated by a controller stationed at h so that the competitors stationed along the sides at f cannot see the die. Each competitor is provided with a number of differently coloured balls, for example twelve red, white and green, to be used over a number of races, whereby he may signal the controller to vary the moves of his horse, unknown to the other competitors, by passing balls down a tube g to the end h. Thus, for example, when the controller receives a red ball from a competitor he moves the corresponding horse d forward a number of divisions twice the number thrown by the die. For a white ball the horse would be moved a number of steps one half the number thrown, and for a green the number thrown by the die to mislead other competitors. The outer tracks have more divisions than the inner tracks and a penalty is awarded against a horse should it be moved on to one of a number of differentiated divisions adjacent an obstacle i. The balls are normally located in closed competitor boxes f. An objection " indicator j comprising red and white balls j<2>, j<1> operable by the controller through strings passing under the box c, may be provided. The tracks may be extended one or more divisions beyond the starting line to provide for handicap racing. The apparatus may be used on a table indoors or outdoors and a totalisator provided for betting.

Title: Treatment of zinciferous materials for the removal of cadmium or cadmium together with lead
IPC: C22B19/02
Filed: 1930-06-04
Abstract: Zinciferous material is treated for the removal of cadmium, or cadmium and lead, by subjecting it as a porous moist layer to a sintering operation in the presence of a chloridizing agent under conditions rendering incapable, or tending to prevent, the formation of strongly basic reaction products, so that cadmium and lead chlorides are votatilized with substantially no volatilization of zinc.  Chlorinating agents specified are an aqueous solution of zinc chloride; or hydrochloric acid; or zinc sulphate, sulphuric or other acid and a chloride such as of sodium, calcium or barium.  In one method of procedure, partly roasted zinciferous concentrate is mixed with 5 per cent of coal dust and say 5 per cent of zinc chloride in solution, the amount of water used being such as will give a suitable consistency to the mixture.  Dependent on the quality of the ore 5-30 per cent is p  employed.  A minimum of work is expended in the mixing.  The ignition period should be about six times that required to ignite the surface of the charge, and the discharged sinter should not be red hot.  The volatilized fume may be collected in water, and the lead and cadmium replaced by zinc.  The chloride solution thus obtained may be re-used in the sintering operation.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the removal of other impurities, tin, antimony, and bismuth being specified.  This subject-matter does not appear in the Specification as accepted.ALSO:Zinciferous material is treated for the removal of cadmium, or cadmium and lead, by subjecting it as a porous moist layer to a sintering operation in the presence of a chloridizing agent under conditions rendering incapable, or tending to prevent, the formation of strongly basic reaction products, so that cadmium and lead chlorides are volatilized with substantially no volatilization of zinc.
