A self-emulsifiable resin powder can be dispersed in water without utilizing additional surfactants or expending large amounts of mechanical energy. Such self-emulsifiable resin powders offer numerous distinct advantages over conventional latices. One of the most important benefits that is realized by utilizing self-emulsifiable resin powders is that they can be shipped dry which is the equivalent...

A fault monitoring apparatus for a multislation pumping system used in irrigation. The pumping system comprises a pump and a series of channels connected to stations 1 - 8 each having an electrically actuable solenoid valve. The apparatus includes a first sensor to monitor the activity of each station, and a second sensor to sense a possible faulty pressure condition of the pump. The second sensor...

1. Coil body for electrical wire windings for transformers, chokes or the like, with a box-like basic part (1) having four faces situated at right angles to one another and for accomodating an iron core, wherein on either side the basic part carries flanges (6 to 13) which preferably lie in parallel planes and which delimit the width of the winding to be received, characterized in that a cover-lik...

A textile material for use in connection with a carrier includes a non-woven fibrous layer which has an irregular surface, and a plurality of separate, round, fiber aggregates, each composed of substantially spherically intermingled fibers. A multiplicity of connecting fibers connects the fiber aggregates to one another.

A process for the production of silicon in a low-shaft electric furnace, in which raw-material blanks are first formed which contain fine-grain silicon dioxide, e.g. in the form of sand, and carbon in excess in respect of the reduction to silicon carbide and the raw-material blanks are introduced into the low-shaft furnance as a charge in mixture with silicon dioxide in lump form. The silicon diox...

A buoy for storing rope connected to an underwater article such as lobster pot comprises a buoyant casing having two side portions connected together and a reel rotatably mounted between the side portions and carrying a length of rope one or both outer ends of which are connectible to the lobster pot or the like article. A central portion of one end of the reel is accessible from a side of the buo...

A macroscopic baser (boson equivalent of a laser). Bosons such as deuterium particles generated by an ion source (2) are injected into a vacuum tube (1), so as to execute motion on a circulatory path therein. Movement of the bosons in this path may be effected by the use of bending magnets (3) and (4) and focusing of the bosons into a circulating stream is assisted by quatropole magnets (5) and (6...

A manually movable trolley for transporting a load unit (21), for example a gas bottle, on a floor surface, for example a floor in a workshop, has a support device (7) for supporting the load unit (21) and a wheel device (6) for resting on a first floor surface (20). The support and wheel devices (7, 6, respectively) are movable with respect to one another in such a manner that in the case of the ...

A titanium composite having a coil-shaped skeletal structure on the surface, comprising a titanium or titanium alloy substrate and one or more layers of a coil-shaped skeletal titanium or titanium alloy structure that is firmly attached to the surface of said substrate and a process for producing a titanium composite having a coil-shaped skeletal structure on a surface of a titanium or titanium al...

A silo for storing alumina having a conical outlet at the bottom thereof is fitted with an exchangeable feeding unit mounted over the conical outlet opening. The feeding unit is adapted to close off the outlet opening when in the non-operative position. The feeding unit can take various forms and includes at least one injection nozzle for fluidizing the particulate material.

Conventional fused salt reduction cells feature anode conductor sections which are spaced apart and have the function of feeding electric current to the anodes via anode rods. An electrically insulated footbridge positioned over the cell between the anode conductor sections makes it possible to walk above the cell. A housing with slight positive pressure created by the supply of fresh air to it, i...
