The piston is hollow and slides over the cylinder which projects downwards from the cylinder head. Four compression chambers are thus formed, one above the piston crown, one under the piston skirt and one inside the piston. The firing of the ignition plugs is so arranged that the engine has one working stroke every revolution and is thus equivalent to a conventional four cylinder engine. The engine is also provided with hydraulically operated valves.

Title: Cold jets for local chilling of extruded (film) profiles - to obtain thick zones for .e.g strong borders for bag mouths
IPC: B29C48/86
Filed: 1976-01-29
Abstract: Longitudinal zones of enhanced thickness are generated in extruded thermoplastic film by using cold (air) jets to chill. selected parts of the extrudate leaving the die lips. Used esp. for modifying tubular extrusion blown film along >=2 longitudinal axes, pref. symmetrically deployed around the extrudate circumference, to produce bands 2-5 x thicker than most of the final profile. The thick zones may be divided longitudinally to generate film with thick borders for reinforced edges of bags made from the film. Also suitable for making slings for carrying spring vegetables etc. Cold jets are simpler to vary in intensity or position than conventional systems for physically shifting die lip or channel profiles to vary extrudate thickness.

Title: Separator to remove magnetic particles from slurries - esp. using superconductor electromagnets
IPC: B03C1/027
Filed: 1976-04-12
Abstract: The specific. describes a sepn. chamber contg. a porous packing of magnetisable particles between its inlet and its outlet and intended as part of a system for sepn. of magnetisable particles suspended in a flow medium. According to the novelty, at least one deflecting baffle is provided in the packing, the baffle being so arranged that it interrupts the otherwise shortest path between the inlet and the outlet. As a result the flowing medium is contrained to flow along a path by the baffle which is greater than the shortest path from inlet to outlet. A smaller separator is achieved for the same throughput and efficiency. This considerably reduces costs when superconductance is employed to generate magnetic field using cryogenic cooling.

Title: Studded drum for hot perforation of thermoplastic film - to produce holes with thickened, smooth tear resistant borders
IPC: B26F3/06
Filed: 1977-01-31
Abstract: Appts. for continuously perforating thermoplastic film comprises a rotating drum provided with heated studs and partially enclosed by a shroud which controls the film/drum clearance. The shroud is slightly eccentric relative to the drum axis and is evacuated so that the film path makes tangential contact with the stud crowns so as to be softened before being perforated as the shroud/drum clearance progressively reduces. Suitable for producing holes with slightly thickened and smooth fused borders. Produces holes more quickly than hot air jet drills and with higher tear resistance than cold puncture borders.

Title: Rotating fluidized bed combustor - has sand rotated in horizontal cylindrical drum with steam blown through heated falling sand
IPC: F23G5/30
Filed: 1977-03-04
Abstract: The heated fluidised bed is formed by rotating a body of sand in a horizontal cylindrical drum, lifting and dropping sand from the bed through the open portion of the drum, and heating the region through which the sand drops. The drum is formed by a cylindrical water wall of pipes connected to a water source and a steam outlet, and annular end plates hold the sand bed and define inlet and outlet openings in the drum. Waste material is simply dumped through the inlet opening and ash is automatically discharged through the outlet opening. The sand is pref. lifted by small cross section, scoop-like baffles so that the coolest sand from the bottom of the bed is heated, and waste particles are not removed from the bed. Auxiliary air can be introduced into the sand bed through a manifold-pipe arrangement.

Title: Rivet setting machine with automatic feed - has punch mounted on sliding block and safety device actuated by movement of rivet holder to rest position
Inventor: BARTON GRAHAM WALTER
IPC: B21J15/10
Filed: 1977-03-08
Abstract: The machine comprises a punch (10) mounted in a sliding block (11) which slides vertically in the machine's framework and is operated by an electric motor. A rivet magazine (13) feeds rivets via a guide bar (16) to the rivet holder (12) and is operated by a hydraulic jack (17) and piston rod (18). The rivet holder can be moved independently from the punch, either to a position of rest in which case a safety device will not allow the punch to be operated, or to the working position. The safety device also ensures that rivets cannot be fed from the magazine unless the rivet holder is in its working position.
