Thermoplastics film having a thickness not greater than 100 microns preferably not greater than 50 microns comprising at least 70 wt% high density polyethylene (density not less than 935 kg m<3>) characterised in that the film has a total haze (ASTMD 1003-61/70, Procedure A) less than 50% and a clarity (ASTMD 1746-70) of at least 25%. The film can be manufactured by pressing raw polyolefin film (1...

A reticulate primary electrode, usually cathode (36), and method for making for use in an electrochemical cell (10). The cathode (36) is openly porous, in substantial physical contact with a separator (16) used in the cell (10) for separating anode (22) and cathode compartment (24) within the cell (10), and intermetallically bound to a cathodic current collector (38) used within the cell (10).

The sports cushion has a one-piece casing with a single-sided, plastics lined weave. The casing is folded along one cusion side, and the brightly coloured plastics cover is positioned on the outside. - The casing is filled with small pieces of plastics foam, and at its corners are slanting seams (8) which limit unfilled compartments through which loops (10) are fitted. Double cords (11) are attach...

The present invention concerns an arrangement in a mill for disintegration and/or mixing of materials such as dirt, bark, etc. In the mill, the material being disintegrated drops down under force of gravity from an inlet opening 4 at the top of the mill through a shaft 1 in the mill toward an outlet opening 5 at the bottom thereof. In this process, the material passes through disintegrating elemen...

The semiconductor store allowing data to be read-in, stored and read-out simultaneously in two directions, has two multi-bit data lines (1l..1k;2l..2k) coupled to each cell (3ll..3kn) of the storage matrix. Each storage cell (3ll-3kn) has a storage element (4) and two transistors (5,6) coupled to respective data lines (1l..1k;2l..2k). The store also has read-in circuits (11l..11k) each coupled to ...

The current feed to the three-phase motor driven in a primary direction is interrupted, and after the elapse of a period set by a time delay relay, is reconnected after changing of at least two phase connections to it. Thus, the motor and the fan are driven in the opposite direction, and because of the fan characteristics its effect is altered but its air flow direction remains unvaried. - The con...

Annular magnetic unit has several curved permanent magnets arranged in annular groups. These are arranged on the bottom of the outer mould. Both the inner and outer surfaces have alternate N and S poles. Around the outer surface of the magnets are iron pieces. There is an space between the ends of the magnets and between the outside of the iron pieces and the outer mould. Plastic is injected to fi...

The flashing, to seal the hole where a chimney, or similar, passes through a roof skin, comprises a watertight-fastened flexible panel-type piece, and cylindrical enclosing collar piece. It is formed from an unworked piece (1) of expanding rubber, synthetic rubber or similar, with a round hole (2) smaller than the chimney cross-section. - The flashing assembly is drawn over the chimney from the to...

The direct current fed light-arc furnace is for direct reduction of metal oxides in powder form, such as iron, nickel, cobalt and/or oxides of metals within the iron group of the periodical system. The furnace comprises a container with at least one hollow electrode (2) connected as cathode, and at least one anode-connected bottom contact (4) or base electrode. In the bath periphery, in or at the ...
