The invention under proposal is a system for feeding aggregate to hammer mills producing sand or other granular material in general, its function being to provide a regulated acceleration of the immission of raw material for processing and the elimination of contact between the hammers and the material to be crushed during those unfavourable moments which give rise to the build-up of unprocessed m...

A multi-coat painting process for metal substrates comprises (a) applying and stoving an electrophoretic primer, (b) applying a water-based coloured and/or effect basecoat (I) directly onto the stoved primer with no other intermediate coats, and opt. (c) applying a clearcoat. Basecoat compsn. (I) contains water-dilutable binder(s) with no OH gps. or with an OH gp. content corresp. to an OH no. of ...

Apparatus for dispensing a predetermined length of yarn (1) in which the yarn (1) is drawn from a yarn supply (2) by a transfer means (3). The transfer means (3) includes one, and preferably two, transfer members (4,5) around which the yarn (1) is wound. Rotation of the transfer member or members (4, 5) draws yarn (1) from the yarn supply (2). The surface speed of the rotating transfer member or m...

The film comprises a mixture of calcined silicone particles and fumed silica agglomerates in which essentially all of the calcined silicone particles have a particle size below about 7 microns; and essentially all the fumed silica agglomerates have a discrete agglomerate size below 1 micron. The film very clear...

A method is disclosed for configuring software to monitor, generate, acquire, collect, store and analyze PM data from telecommunication equipment, including the steps of maintaining a library of product-independent PM data processing modules maintaining product-dependent data relating selected ones of the processing modules with each of a plurality of telecommunication equipment systems, and gener...

Multiword information is encoded as based on multibit symbols in relative contiguity with respect to a medium, whilst providing wordwise interleaving and wordwise error protection code facilities. This may provide error locative clues across words of multiword groups, that originate in high protectivity clue words and point to low protectivity target words. The clue words may have a first uniform ...

A search system for a tool. A border cable separates inner and outer areas. A generator feeds the border cable with current, whose magnetic field affects a sensing unit on the tool, and the sensing unit emits signals to a control unit that directs the tool's motion. The current contains at least two components of different frequency. A search cable is placed within the inner area so that it separa...
