Title: Coffee machine with quick-action feed - piston sealed in cylinder and four-way hydraulic distributor
IPC: A47J31/40
Filed: 1974-06-14
Abstract: The machine is operated by pressing the button which sets up the electric circuit so that the pump begins to convey water into the upper zone of the chamber containing the piston so that owing to pressure the piston is forced down and the amount of water in the lower zone is forced into the outlet pipe and from there to the heat exchanger. When the shaft of the piston rod contacts one of the bars of the dosing control device the movable part inside the distributor is displaced so that the connections between the different pipes are changed and pump supplies water to the lower zone of the chamber to cause the piston to rise. The water collected in the upper zone is passed through a pipe and the distributor into the outlet pipe and from there to the heat exchanger. As soon as the piston has moved right to the top, the piston rod breaks the circuit for the machine and starts the supply to the pump.

Title: Internal sleeve for adjusting traverse of injection moulding tool - suitable for large or small machines
IPC: B29C45/67
Filed: 1975-09-16
Abstract: An adjustable stop for restricting the travel of a hydraulic piston used to traverse the mobile half of an injection moulding tool, where the piston is extended by a hollow body accommodating an internal concentric sleeve which can be rotated by a coaxial key extending through the hydraulic chamber. Rotation of the sleeve winds it in or out of a threaded opening in the main piston, thus adjusting the distance by which the sleeve protrudes from the face of the piston into the hydraulic chamber. Retraction of the piston into the chamber is thus restricted by the sleeve head butting against the end of the hydraulic chamber. An internal flange prevents the sleeve from being totally withdrawn from the hollow body. Used for adjusting the traverse distance of the mould to suit different depths of tool and moulding without involving wasteful hydraulic movement The concentric design allows component wall thickness to be relatively thick and minimises the torsional moments applied to the components for the overall size of the unit, resulting in the mechanism being relatively robust and/or suitable for scaling down to suit small machines.
