On an automatic textile winding machine when yarn is wound from cops to a crosswound reel, appts. is fitted to prevent the yarn snarling on leaving the cop. This consists of two shaped wires in the manner of a pair of tongs, which curl around the neck of the cop, forming a ring to lock the free end of weft, with a means of releasing the tongs. USE - Partic. for yarn with considerable twist at the ...

A process whereby twin yarn is spun by airjet and then creeled on to a package suitable for twisting, and in the event of a break in one or both threads, they are sepd. and spliced in such a manner that the joins in each thread do not coincide one with the other when wound together. The appts. is also claimed. -

A hydraulic pressure control valve includes a modulator-controlled solenoid assembly which selectively axially displaces a disc armature adjacent thereto. When not attracted by the solenoid, the armature is biased away from the solenoid by a wave spring. Movement of the armature opens and closes the outlet of a lower body member to a source of hydraulic fluid under pressure. The armature is improv...

A process for applying a pre-cured tread stock (62), Fig 2, to a tire carcass 12 in a retreading operation includes rotating the prepared tire carcass 12 on a suitable apparatus 14 and while the tire carcass 12 is rotating a continuous ribbon 517 of cushion gum material is extruded across the crown 12a of the rotating tire carcass 12. The temperature of the cushion gum material must be maintained ...

Use of polyfluoroalkanes of the formula CX3-CY2-R (I> in which X radicals on the same C atom stand for hydrogen and/or fluorine, Y radicals on the same C atom stand for hydrogen, fluorine and/or CF3 and R stands for CH2F, CHF2, CH3, CF3, CF2-CH3, CF2CH2F, CH2-CH3, CH2-CH2-CH3 or -CH(CH3)-CH3 and a molecule of the formula (I) contains at least two fluorine atoms, as propellant gases. o

Filter insert, in particular of a parallelepipedal shape, comprising a multiplicity of pleat walls arranged in zigzag-shaped pleating for a medium to be filtered passing through the insert in the direction from one edge region of the zigzag pleating to the opposite edge region of the pleating, comprising a material permeable for the medium to be filtered having island-shaped projections produced b...

An arrangement for monitoring the function of a programmable electronic switching circuit, such as, a microprocessor or microcomputer, characterized by a monitoring switch is associated with and is connected with the reset input and the clear input of the programmable electronic switching circuit and the monitoring switch includes a measuring circuit for determining the program length.

A process for preparing light-weight, insulating and semi-rigid or rigid elements, essentially comprises impregnating a porous supple material having an internal structure with preferentially open cells, with the desired quantity of a solution of a compound selected from the group comprising isocyanates, and having consequently in its formula at least a -NCO group, the material optionally having t...
