Pref., the splicing appts. (1), with a cold conductor component as a heating source, is fitted to each winding station, for additional heat at the splicing head (4). The yarn ends (12a,13a...

A yarn feed and clearer mechanism for textile machinery has a driven barrel accumulator and a thread detector in the guide, coupled to a tension and adjustable knot indicator device. USE - As a combined thread guide and detector device, adjustable to all types and counts of yarn.

The invention relates to a method and an apparatus for building a tyre carcass during the expansion stage, which has a gripping head system with two rotatable and axially movable one-part bead-holding discs. In order to obtain a sturdy and simply constructed carcass holder and to permit automatic fitting-on of the carcass, it is proposed that the bead-holding discs are swivelled about an axis perp...

In a process for allocating data sets to time values of a consecutive sequence, each time value is stored as a data string in a field. Read-out of a given time value starts at the beginning of the data string and continues up to the selected time value. A time value can be allocated to each unit of a data string and vice versa.

A fuel system for an internal combustion engine includes a pump/injector having an actuating winding to which power is supplied by a first electronic means. A first control signal is supplied by a second electronic means to energize the winding and a second control signal is supplied by a third electronic means to de-energize the winding. The third electronic means calculates the time at which the...

The invention relates to a safety device in deliverers of printing machines for inserting pile plates above the sheet pile. The object of the invention - to provide a safety device in deliverers of printing machines, in which all the required movement sequences are triggered by means of the pile plate to be inserted without intermediate operating manipulations - is achieved in that the safety devi...

This invention relates to polyurethane foams capable of being welded by high frequency welding and a process for producing the same, characterized by the addition of certain ammonium salts of acids containing phosphorus to the starting components for the polyurethane foam in order that the polyurethane starting materials and the polyurethanes contain from 0.1 to 10%, by weight, of ammonium salts o...
