Title: Paper fibre process cylinder - has slurry deposited on surface by a slit and pressed in zone formed by a lip plate
Inventor: ATTWOOD BRIAN WILLIAM
IPC: D21F1/04
Filed: 1974-08-03
Abstract: An apparatus is claimed for the manufacture of paper web material, where the fibre slurry is carried on the mantle of a mesh cylinder for the fluid to be extracted followed by drying and pressing, with a fibre slurry feed head located near the mesh cylinder with a distribution chamber and inlets for the fibre slurry. The slurry is passed out of the distribution chamber under pressure through a slit to be deposited on the mantle of the cylinder.

Title: Additional wheel drive for vehicles - has balance qualities acting as pendulum for low loss control of continuously variable drive
Inventor: PITZ HEINRICH
IPC: F16H39/00
Filed: 1974-09-30

Title: Hydrazine-fuelled propulsion for submerged vessel e.g. torpedo - producing no wake or bubbles and allowing high submerged range
Inventor: ERDMANN HERMANN
IPC: F42B19/20
Filed: 1974-12-17
Abstract: A bubble-free underwater propulsion system produces energy in the form of gas and/or steam from the catalytic decomposition of hydrazine as a hydrazine/water mixture, which is passed to a turbine. The turbine exhaust gas is subjected to condensation, the soluble condensate then being pumped into the sea while a compressor forces remaining gas back into the hydrazine tank where it is available for propelling the hydrazine or hydrazine/water mixture. The fuel may be a mixture of 65% hydrazine - 35% water, or hydrazine monohydrate, or pure hydrazine. The last-mentioned may be mixed with the water necessary to give bubble-free operation just before entering the gas-generator. The system is free of the limits on operating range imposed by battery size and weight if using electric propulsion to achieve bubble avoidance.
