Abstract: 746,323. Valve gear; regulating. MOLLER, E., POUNDER, C. C., and REBBECK, Sir F. E. March 24, 1954, No. 8565/54. Class 7(6) In a supercharged duelfuel multicylinder engine having a pair of simultaneously operated inlet valves 1, 2, and a pair of simultaneously operated exhaust valves for each cylinder and wherein gaseous fuel is supplied to the super-charging air duct through gas admission valves 9, one for each cylinder, the valves 9 are operated hydraulically from the mechanical operating means 3 of either the inlet valves or the exhaust valves. The valves 1, 2 are operated simultaneously from a rocker 4 through a cross-beam 3 guided by a stem 5 which forms the plunger of a pump supplied with hydraulic fluid from a reservoir 6. On each downward stroke of the plunger 5 to open the valves 1, 2, of one cylinder, the hydraulic fluid is transmitted through a pipe 7 to a cylinder 12 formed in the stem of a valve 9 associated with another engine cylinder, whereupon the valve 9 which is fed with gaseous fuel from a manifold 21 is opened to supply gaseous fuel to the air intake pipe adjacent the intake port. The lift of the valve is controlled by a stop lever 16 engaging a flange 18 on the valve stem and adjusted by a cam 15 actuated from the fuel supply control means or engine governor, the head 13 of the valve 9 being conical so that the fuel supply varies with variations in lift. An accumulator piston 19 absorbs excess fluid delivered by the plunger 5. The valve 9 of one cylinder is actuated either from the inlet valve gear or the exhaust valve gear of another cylinder. In a modification the lift of the valve 9 is controlled by vary ing the output of the pump 5 which is surrounded by a sleeve with a helical control port therein, the sleeve being actuate from the fuel supply control means or engine governor.

Abstract: 289,242. Hughes, T., and Harwood, A. April 20, 1927. Rope railways and tramways. - In rope haulage systems of the kind in which the rope is received in the groove of a horizontal guide pulley at bends in the track, the rope is fitted with conical ejectors to free it from the guide pulley while the loaded vehicle or tram passes. Thus the double-conical member, made in two halves clamped over the rope 10 by the screws 7, runs in advance of each tram until the front end enters the pulley groove, after which the gradually increasing diameter raises the member in the groove until the rope is clear of the rim. The haulage tension at this point raises the rope above the pulley and the tram passes on the forced rope. The halves of the conical member may grip the rope directly, but in the construction shown in Fig. 4, a member 14, mounted in a recess in the conical member is clamped on the rope to prevent axial movement, and the conical member rotates freely on the rope.
