Title: Hydrophilic, porous synthetic polymer sheets - by reacting oppositely charged ionic polymers and-or monomers in sheet-forming mixture
IPC: C08J9/16
Filed: 1975-07-01
Abstract: Hydrophilic properties, esp. the water vapour absorption, of porous synthetic polymer sheets, esp. synthetic leathers for use in garments and footwear, are increased by adding to the raw material mixt. a hydrophilic component (I), consisting of (a) oppositely charged ionic polymers, (b) a mixt. of oppositely charged ionic polymers and monomers, or (c) a mixt. of oppositely charged monomers, and converting (I) into its water insoluble form before, during or after the formation of the sheet, by polyreactions. Enables the water vapour absorption of the sheets to be controlled at a desired value. A hydrophilic gradient can be formed over the cross section of the sheet. The prods. provide garments and footwear with a satisfactory moisture permeability.

Title: Fitting for butt joining frame sections - has quarter turn fixing pin which holds mitred joints
IPC: E06B3/988
Filed: 1975-12-04
Abstract: This assembly fitting joins identical section frame elements together. The pieces are locked together by a quarter turn of a fixing screw. A joggled plate (16) is fixed to one face (9) of the frame and projects at right angles to the edge (11a). The other element of the frame has a complementary housing (14) fixed to it and also projecting atright angles to the edge. The plate is inserted into the housing on assembly and the two held together by a cylindrical transverse pin (17). A circular hole (19, 21) is cut in the housing and a square hole (22) in the plate. The locking action is achieved by cutting a flat (33) on the pin (17) which registers on the edge of the square hole, which penetrates furthest into the housing. When the pin is rotated, it acts as a cam and draws the plate further into the housing. This action draws the edges of the frame members together and subsequently holds them in compression.

Title: Electroerosion spark machining generator - with comparator for actual and desired values of voltage versus time curve envelopes
IPC: B23H1/02
Filed: 1975-12-09
Abstract: The generator includes a control unit which produces upper and lower threshold signals as max. and min. envelopes of the voltage-versus-time curve. A second control unit compares this with the actual value in the working circuit with the spark gas and operates a third control unit to adjust the working pulse across the gap to lie within the envelope pair. This can be used to get any desired shape of envelope amplitude, repetition frequency and duty factor to suit the workpiece conditions. The response time is extremely fast and suitable for modern optimisation control systems.

Title: Metallic or non-metallic items coated with impurities - are cleaned by agitation in a rubber lined drum
Inventor: BLANDIN ROGER
IPC: B02C17/22
Filed: 1976-09-21
Abstract: Metallic or non-metallic items coated with one or more impurity materials which adhere to the items are cleaned to separate the materials from the items. The items are agitated within a drum in a manner causing the items to strike each other several times, the internal walls of the drum being coated with an elastic material such as natural or synthetic rubber which is in contact with the items. The procedure is particularly suitable for the cleaning of pre-baked carbon anodes used to produce aluminium electrolytically and from the electrolytic bath and with iron from steel conducting bars embedded in the anodes. The procedure is much quicker and less energy intensive than conventional shot- or sand-blasting cleaning techniques.

Title: Spreading appts. for granular substances - feeds bulk grain via hopper to contra-rotating spinning discs
IPC: A01C17/00
Filed: 1977-03-03
Abstract: Grain (15) in bulk is carried in a tank (1) of a trailer vehicle which is towed behind a tractor. The grain is fed to a hopper (2) at the rear by a belt conveyor (10). An auger (21) is mounted transversely in the hopper. The auger displaces the grain from the sides to the centre where it discharges to two laterally spaced spinning discs (30). A deflector plate (23) divides the grain so that equal amounts fall to each disc. Flow through the hopper opening is controlled by a plate (24) and a jack (25). The conveyor, auger and discs are driven from the tractor power take-off. A screw jack (39) controls the inclination of the discs whereby the spread can be varied. The discs rotate in opposite directions.
