Title: Engine deriving power from dissociation of water - using electrically heated catalyst coated with zinc-antimony alloy
IPC: F02B47/02
Filed: 1974-01-23
Abstract: The pump injects water in the form of a mist into the cylinder. An electric heated catalyst which is coated with an alloy of zinc and antimony in the ratio of 8 to 12, causes the water to dissociate into hydrogen and oxygen. This dissociation produces a pressure which forces the piston downwards until it opens an exhaust port which allows the drops of water to flow into a reservoir and return to the pump. These drops of water are produced by the recombination of the gases due to a spark from a plug which also causes an implosion forcing the piston upwards.

Title: Metal cutting machine with reciprocating head - uses hydraulic circuit with restrictor valve to give fast and slow movements
IPC: B23D47/10
Filed: 1974-03-29
Abstract: A saw blade is mounted on ahead sliding on a column. Rotation of the head is presented by an extension of the head and another column. The head is moved by a double acting pneumatic actuator on top of the machine with a speed controlled by a hydraulic circuit and a restrictor valve. The head initially moves rapidly downward, a sleeve sliding along the actuator piston rod. After this rapid movement the piston is pushed downwards in the cylinder, and fluid flows from beneath the piston via a conduit and restrictor valve to above the piston. This gives a slow cutting movement. A rapid return stroke is permitted by a flap valve on top of the piston.
