Title: Spark erosion machine
Inventor: DIVERS SYDNEY VALENTINE
IPC: B23H1/02
Filed: 1984-09-18
Abstract: Motor 64 drives the wiper of variable resistor 65 at slow speed through gearbox 66 slowly and progressively to increase the erosion current supplied to the spark gap between an electrode (34, Figure 1) and a workpiece (14, Figure 1). The gap voltage is sensed at the coil of relay 74 which becomes de-energised upon the spark generating voltage reducing below a predetermined value, thereby de-energising relays 77 and 80. The motor 64 is then driven rapidly in reverse to increase the spark gap voltage, until the relay 74 is re-energised for erosion to be resumed, and the relays 77 and 80 return to their condition providing for the motor 64 to be driven again, thereby automatically to ensure optimum erosion current at the spark gap. Wafers 87 and 88 serve to define limits of rotation of the motor. <IMAGE>

Title: Waste management system
Inventor: COPSON ALEXANDER GEORGE
IPC: B09B1/00
Filed: 1985-08-02
Abstract: The rapid growth of urban areas provides enormous waste management problems for the responsible municipal authorities. Waste is transported to a processing plant where it is mixed with water and mechanically broken down to form a pumpable waste/water slurry. The slurry is pumped on board a ship either from a dockside processing plant directly on board or from an inland plant by a suitable pipeline. When a ship has a full load it sails to a deep ocean site where slurry in pumpable form is passed down a flexible pipe and extruded onto the seabed. It may be advantageous to provide a water-jetting pipe in conjunction with the slurry extrusion pipe so that a water jet can be used to cut a shallow trench for the slurry.
