A drill is described having a metal bit carrier part on which a sintered metal bit is placed. The bit possesses at least one enclosed helical cooling channel which continues in alignment into a corresponding cooling channel in the bit carrier part. This drill is particularly characterized by very great mechanical and thermal stability, which is not adversely affected in any way by the system of co...

With the aid of a process and apparatus for initiating the fermentation of wort using krausen (heads), krausen and wort are first introduced from below into an upright fermentation tank, then, reversing the filling direction, a mixture of more wort and circulated young beer is pumped in from above. A corresponding amount of young beer is removed at the bottom and fed to the main fermentation. The ...

A butcher's meat saw has a housing from which extends a flat guide plate having an edge along which is slidable a blade reciprocated by an eccentric-type drive mechanism within the housing. Either the edge of the guide or the edge of the blade is formed with a groove and the other edge fits in this groove. One of these edges is furthermore formed with laterally opened notches so as to facilitate c...

The invention relates to a process for strongly bonding the ends of profiles of vulcanised rubber mixtures based on natural rubber or styrene-butadiene rubber by coating the ends with an adhesive, applying heat and pressing the ends together. The bonding operation is essentially carried out by first subjecting the faces to be bonded to oxidative or chlorinating treatment and subsequently to treatm...

An axially symmetric air-core choke coil for high voltage applications. The coil includes a plurality of radially concentric, helically wound layers of windings. Non-insulated wire cable is used to produce each winding. Therefore, adjacent turns of each winding, as well as adjacent layers are spaced from one another. Separation between adjacent turns of each layer is provided through longitudinall...
