Abstract: Gaseous hydrocarbons and liquid hydrocarbons of low boiling point are converted into a gas containing hydrogen and carbon monoxide by passing the hydrocarbon in admixture with steam and/or carbon dioxide through an externally heated multi-tubular reaction zone containing a catalyst while maintaining at the outlet to the reaction zone a temperature between 1350 DEG  and 1700 DEG F., preferably between 1450 DEG  and 1600 DEG F., and a pressure of at least 50 p.s.i.g., preferably between 65 and 150 p.s.i.g., the steam to methane or methane equivalent mol. ratio being at least 1,8:1 and the space velocity corresponding to at least 700 volumes of methane or methane equivalent per hour per volume of catalyst.  The hydrocarbon feed is preheated to between 400 DEG  and 1250 DEG F., preferably between 800 DEG  and 1150 DEG F., while the steam to methane or methane equivalent ratio is preferably between 2,1:1 and 2,6:1.  The tubes of the reaction zone have an outside diameter of between 2 1/2 and 5 inches and the catalyst is preferably nickel oxide or nickel and calcium oxides on a silica-alumina support in the form of spheres or pellets having a diameter or length between 1/4 and inch.

Means for raising or lowering a series of tetrahedral containers 1, Fig. 3, comprises a fixed helical brass rail 11, Fig. 1, of circular cross-section on which rest the bases of the containers and a rotatable concentric cylindrical member 7 provided with vertical grooves 12 of V-shaped cross-section which engage the containers. The apparatus is shown in Fig. 1 as arranged to deliver cartons of liquid from a coinfreed vending machine through a shoot 19, entrance to which is normally prevented by a spring-controlled door 22. When the motor driving the cylinder 7 is started by a coinactuated switch, the lowest container falls off the end 18 of the helix on to the door and depresses it to allow passage to the shoot. The door is fast on a spindle which has a short arm 27 fixed thereto. As the door moves downwards, the arm 27 causes movement of an arm 28 free on the spindle. Movement of the latter arm resets a spring-loaded trip-lever and the switch controlling the motor is opened. When the door returns to the horizontal position, the arm 28 remains in its lowered position until another coin is inserted. Until this happens the door can be swung to-and-fro manually, but access to the containers is prevented by the rigid flap 29 which is positioned at right-angles to the plane of the door.

Abstract: 291,861. Vickers, Ltd., and Wardle, J. March 8, 1927. Valves controlled by pilot or relay valves.-A valve-actuating device particularly applicable for operating the Kingston valves controlling the admission and expulsion of water to and from the ballast tanks of submarines has the operating member connected to the valve member by an intermediate device which allows a limited relative movement so that when the valve is to be opened for discharge it is not actually lifted from its seat until the internal air pressure exceeds the external pressure. The rod d attached to the main piston D and the spindle a of the valve A are provided with flanged heads d<1>. d<11> arranged to work in a box f carried by a crosshead f operated by a pair of pistons F. When opening the valve to expel water the control valve G is operated to admit pressure to the cylinders E' which moves the crosshead into contact with the stops C<1> and positions the box f<1> so that when the internal pressure exceeds the external the valve opens. To open the valve to admit water, pressure is supplied to the cylinders E, E' and to the top of the main piston, and to hold the valve closed pressure is admitted below the piston D. In the neutral position all the control pipes are cut off from the pressure main.

During operation peak pressure pulses are absorbed by a chamber 63. The cylinder 44 for the piston 52 is connected by a coiled tube 65 to a liquid reservoir cylinder 54 Fig. 5 (not shown). When a valve 66 is closed the pressure pulses are fed into an auxiliary chamber 68 in addition to the chamber 63 thereby allowing the generator to continue to operate although the shearing devices are inoperative.

Void [Published under Sect. 91 of the Acts]. [Class 103 (v).] In a hydraulic or like railway-vehicle buffer of the kind, as shown in Fig. 1, in which a piston c is arranged to displace liquid from one portion h of a chamber to another portion g, the latter portion having an air space g<1> to compensate for the varying volume of piston rod d in the chamber, the air space is made of considerably greater volume than is customary, with the object of reducing the pressure on the piston rod stuffing-box f. Such increased air space may be obtained by various methods, for example, as shown in Fig. 2, by locating the usual spring e in the liquid chamber instead of in a separate part of the plunger ; by the use of partitions, flexible diaphragms or movable pistons between the air space and the liquid chamber; by the use of air containing compressible balls in the liquid chamber; or by connecting the air space to an auxiliary external air-space.

Target apparatus for "hoop-1a" comprises a tank 1 in which float objects 18 connected by submerged mechanism to. means for giving the objects a forward motion and for imparting to the objects a superimposed auxiliary motion, which may be a sideways motion of the whole object or a submerging motion of the whole object or a part thereof, or both. As shown in Figs. 1 and 2, a central pillar 2 has mounted thereon two sets 5, 6 of spokes having wheels 4 running on guides 3 and rotated at different speeds by means, not shown. Each object is connected by mechanism 17, 16, 11 to a carriage 9 guided by rollers 10 on a rail 7 rotating with the spokes 6. A loop in the link 11 engages a spoke 5 to rotate the object about the pillar 2 and, because the rail 6 is non-circular in shape, the objects perform a non-circular orbit. Different objects 18 may be guided by rails of different shape. The link 16 is connected by links 15, 13 to a roller 14, which at appropriate points of its orbit is engaged by a cam 21 which raises the roller to cause the front part of the object to be temporarily submerged. As shown in Fig. 3, the objects are traversed to and fro between points E and F by a cable 35 driven by a reversing device 42. The object is connected by a cord 36 to a crank arm of a member 32 which engages the cable and also has a squared aperture engaging a squared rod 31 which is partially rotated at intervals by a cord 40 connected to a lever 41 operated by cams or the like to submerge the front of the object. As shown in Fig. 5, the objects are connected by a cord 61 to a towing cable 50 guided by pulleys 53 on a weighted beam 54 and driven by a reversing device 60. The bights of the cables 50 pass over pulleys on a bracket 59 which is moved upwardly at appropriate intervals to allow the beam 54 to descend and thus submerge the objects. The liquid in the tank may be agitated and may be dyed to conceal the towing mechanism.
