Title: Automatic shut-off dispensing nozzle
IPC: B67D7/54
Filed: 1978-06-14
Abstract: An automatic shut-off dispensing nozzle having a manually operable main valve 19 for controlling liquid flow through a spout 14 into a sealed tank, has an auxiliary valve 57 actuated by a diaphragm responsive to the vapour pressure in the tank. When a predetermined pressure exists in the tank the auxiliary valve causes latching mechanism 61 to automatically release and thereby close the main valve. The loading applied to the diaphragm by a spring is adjustable by means 118 to set the predetermined pressure.

Title: Method and Apparatus for Re- Processing Waste Oils
IPC: C10G33/08
Filed: 1979-11-12
Abstract: A method of and apparatus for re- processing waste oil for the production of a fuel oil substitute are described. The waste oil is passed first to a solids separation zone where it is exposed to conditions under which solids separation is achieved, followed by recovering an intermediate oil which is then contacted with water in a three phase separator in which the oil and water are intimately contacted and a water phase and oil product are recovered and the rate of supply of waste oil to the solids separation zone is controlled in dependence on the water content of the oil product from the three phase separator. The process is preferably operated continuously. A system of level controls and pressure switches is described which provide for automatic shutdown of the plant in the event of "seal loss" in the separator or other malfunction of the plant.

Title: Counterbalanced electromagnetic band clutch
IPC: F16D27/02
Filed: 1979-12-18
Abstract: In an electromagnetically operated band clutch (10) comprising a band (52) arranged in a radial gap 50 between driving and driven members (12), (36) and including an electromagnetic coil (32) carried by the driving member (12) to urge the band into driving engagement with the driving member when the clutch is engaged, in order to overcome the centrifugal forces and thereby increase the maximum speed of the engaged clutch, a lever (62) (Figure 2, not shown) is pivotally connected (64) to the driven member.
