  • Dispensing device
    Patent number: 4308978
    Abstract: A dispenser device for liquids including a metering chamber having a valve controlled inlet port and a valve controlled outlet port. An actuator is connected to the two valves to move them between fill and discharge conditions and is arranged to cause the inlet valve to close before opening the outlet valve during transfer from the fill to the discharge condition. The actuator includes a cylinder movable over a piston fixed to the body of the device and the valves respond to movement of the cylinder between two extreme positions corresponding to the fill and discharge conditions respectively. A biasing system urges the cylinder into the fill position at which the inlet valve is open and the outlet valve is closed, and a time delay arrangement operates to retard movement of the cylinder during part of its travel from the discharge position to the fill position.

  • Producing liquid hydrocarbon streams by hydrogenation of fossil-based feedstock
    Patent number: 4308128
    Abstract: An economic route to transport fuels from low grade feedstocks containing organic polycyclic components and mineral and/or metallic components comprises separating the feedstock into (a) a residue containing fuel values and substantially all of the mineral and metallic components and (b) a liquid hydrocarbon fraction; hydrogenating the liquid hydrocarbon fraction; providing hydrogen for the hydrogenation by steam reforming methane-containing gas recovered from the hydrogenated material; and providing the heat for the steam reforming by immersing the reformer reactor tubes in a fluidized bed heated by combustion of residue from the separation step. If the fluidized bed is pressurized, the process can be made substantially self-contained with all the heat and power requirements for steam generation and feedstock compression for hydrogenation and steam reforming being recovered from the flue gas.

  • Buckle for safety belts
    Patent number: 4299014
    Abstract: The invention relates to plate type buckles for safety belts of the kind formed of flat webbing and is particularly concerned with such a buckle wherein engagement between the two parts can only occur when the webbing is not twisted in a way which would lead to slipping occurring when a load is applied to the belt. The buckle comprises a main plate which is attached to one end of the belt and a top plate which is slidably attached in a manner allowing adjustment of the working length of the belt. The belt is turned back in a loop around a webbing bar in the top plate and the main plate has an aperture therethrough capable of passing the loop and a slot in each of opposed longitudinally extending sides of said aperture to extend the width of the aperture for facilitating passage of said top plate in edgewise orientation with respect to said main plate.
