Title: Hydraulic press to extract juice - esp. from grapes for winemaking, increases yield and reduces power consumption
IPC: B30B9/06
Filed: 1973-11-28
Abstract: Hydraulic press for extracting juice from a material, esp. fruit, in which an hydraulic cylinder advances a ram to exert pressure on the material in a radially perforated filter cylinder. The press is pref. programmed automatically to accept into the cylinder a charge of material from a hopper via an open shutter; the ram is advanced, simultaneously closing the hopper shutter and compressing material in the cylinder so that juice is expressed via the filter perforations. The cycle may then proceed:- ram advances to 8 tonnes load and pauses to allow juice to run out, ram advances to 16 tonnes load and pauses again, ram advances to 25 tonnes load and pauses, discharge door swings open to dispose of drained pulp, ram withdraws and complete ccle restarts.

Title: Electrochemical machining metal - using non-conductive inert nozzles and cathodically charged electrolyte
IPC: B23H9/16
Filed: 1973-12-04
Abstract: Holes are drilled in a metal workpiece electrochemically by impinging a jet of cathodically charged electrolyte against a starting surface of the workpiece which is anodically charged. A low potential is maintained until a dimple is formed in the workpiece which will direct the electrolyte away from the workpiece. The potential is increased as cavitation increases and maintained to cause drilling at the point of jet impingement until the hole is formed. The potential is again increased for a period to develop the hole to a desired diameter. Pref, the potential is increased in increments and the nozzle forming the electrolyte jet is positioned below the workpiece at a distance to facilitate electrolyte drainage. A plurality of nozzles are utilised for providing multiple cavities simultaneously.

Title: Stackable tray supporting enamelled tiles during baking - where one set of trays can carry tiles of different thickness
IPC: F27D5/00
Filed: 1976-07-09
Abstract: Modular tray supports workpieces during baking, where the tray is rectangular or square. On one side of the tray are four feet, each of same height and two feet are located along each end of the tray; but the distances sepg. the pair of feet at each end of the tray are different. An identical set of four feet are used on the other side of the tray, each foot of same height. When the trays are stacked vertically so surface is uppermost on all trays, the gap between the trays is the same. But if alternate trays are rotated 180 degrees the gap between the trays become double. Used for the baking of enamelled tiles in a furnace. The tiles are made with different thicknesses; and the invention produces trays which can be stacked vertically in two different ways to obtain either a gap with one height or double height ot suit the tile thicknesses, a single design of tray produces this variation.
