  • Ink jet printing system
    Patent number: 4714931
    Abstract: In a continuous ink jet printing system a viscosity determining means (12) has a measuring tank (29). An inlet (32) to the tank is connected to the system ink circuit to receive ink under pressure and the inlet has a flow restriction. A vent/return pipe (34) vents the tank and enables ink to be returned to the reservoir. An outlet (33) drains ink from the tank and returns it to the pump, the outlet including a valve (13) to open and close the outlet. A level detector (30,31) in the tank is connected to a timer (38) to determine the time taken for the tank to fill from a first level to a second level detected by the level detector and hence to provide a representation of viscosity of the ink.

  • Manually operated impact driver
    Patent number: 4708209
    Abstract: Hand held tool for applying a rotational impact to a fastener. Means including a windable spring are mounted on the tool body for storing energy, which can be release and transmitted mechanically to other means engaging the fastener, to apply a rotational impact force to the fastener. The tool is useful for small fasteners and delicate workpieces, where the rotational impact should be applied with little or no axially-directed thrust force component.

  • Munitions assembly system
    Patent number: 4708048
    Abstract: A system for the rapid assembly of munitions comprising a roller conveyor extending from beneath an on-load gantry, a hoist attached to the on-load gantry, a rail conveyor extending from the on-load gantry to an off-load gantry, a hoist attached to the off-load gantry and dollies which travel between the gantries on the rail conveyor. A munition body is delivered to the on-load gantry by the roller conveyor. The munition body is hoisted onto a dolly and assembly and arming tasks are performed as the munition-laden dolly travels on the rail conveyor. The assembled and armed munition is then removed from the dolly by a hoist on the off-load gantry.

  • Device for preventing abnormal flow of gas fuel from gas fuel injector of diesel engine
    Patent number: 4704997
    Abstract: A device for preventing abnormal flow of gas fuel from a gas fuel injector of a diesel engine. The device has a pipe for supplying a pressurized gas fuel, a fuel injector including a passage connected to the pipe and leading to fuel injection nozzle ports, and a fuel cut-off valve means adapted to close the gas fuel passage upon detection of a reduction of the fuel pressure in the fuel passage. Any abnormal supply of fuel due to stick of the fuel injector is prevented so as to avoid any risk of explosion which otherwise may be caused by the abnormal supply of the gas fuel.

  • Continuous ink jet printing
    Patent number: 4688049
    Abstract: In a continuous ink jet printing method for printing multiple lines of print (13-15), raster of drops is produced in which the differential charge between drops printed on opposite sides of an interline gap (17,18) is increased in comparison with that between adjacent drops to be printed within a line (13-15). At the same time the number of guard drops is maintained the same or is reduced between the printable drops immediately adjacent to the interline gap, so that the distance between printed drops immediately adjacent to the interline gap is increased without increasing the number of drops in the raster.
