The pick-up arms (34,36,37) are pivoted in a block (33) attached to the disc player frame. A beam of light from a laser enters the arm along the pivot axis (M) from above, and is deflected horizontally along a prismatic rod (35) to be focussed (38) onto the underside of the rotating disc (31). Light reflected from the disc passes back along the rod and leaves the arm along the pivot axis (M). T...

The present invention relates to a method and a device at a biological purification step of waste water in aerated basins, whereby one introduces a non-aeration zone provided with a static stirring of the water passing said zone prior to a precipitation step.

It has been surprisingly found that gold compounds may be applied in topical preparations as an effective treatment of local or systemic inflammatory conditions and/or as antibacterial agents. The present invention therefore relates to new pharmaceutical compositions containing gold for topical application, and the use of the composition in treating inflammation and/or bacterial infection.

A composite mass with a major proportion of inorganic material and a minor proportion of organic material, preferably from industrial waste products, is activated by dehydration of its organic constituents whereupon the mass is subjected to a two-phase pyrolytic process. In a first stage, lasting for 2 to 3 hours it is heated to about 600 DEG C. with carbonization of the organic constituents; in ...

The invention relates to a process for producing a three-dimensional stiffening element from a powder selected from the group consisting of a meltable plastic powder and a powder mixture comprising the meltable plastic powder comprising applying the powder to an auxiliary carrier in a template screen printing process with the aid of a template and subsequently transferring the thus obtained stiffe...

For dishwasher-resistant decorations on tableware consisting of silicate materials, bright rare metal preparations are used which consist of one or more organo-compounds of rare metals, an organic carrier and a flux of organic metal compounds, the flux containing an organic silicon compound having three and/or four hydrolysable groups on the silicon atom in quantities of 0.1 to 4 mol of silicon pe...

Method and machine for the production of a polygonal box from a blank (1) of sheet material comprising a set of panels (2, 3, 4, 5). According to the invention: - the said set of panels (2 to 5) is rolled about a mandrel having a polygonal cross section; - the tongue (9) is fixed to the free edge (19) of the end panel (5); - the flaps (11.2 to 11.5) on the same side as the said panels (...

A primary mineral wool web (1) is deposited by a delivery conveyor (2', 3') essentially horizontally onto a receiver conveyor (11) which runs at a significantly lower speed than that of the mineral wool web (1), as a result of which a secondary mineral wool web with a multiple of the surface weight of the primary web (1) is formed. In order to carry out the folding, air from a blow-off box (33, 34...
