To take off a yarn, ribbon or the like over the head of a wound bobbin, the yarn (4) is drawn alternately over one of the two end surfaces (1', 1'') of the bobbin (1). - A mounting (2) inhibits rotation by the bobbin (1). A take-off eyelet (3) is moved between the two take-off points (A,B) at the opposite ends of the mounting axis formed by the bobbin holder (2), where the bobbin (1) is held paral...

A method and a device for cutting gas concrete employing cutting wires (35), whereby, in order to decrease shocks and vibrations, and in order to cut blocks of gas concrete more rapidly and with a finer surface structure, said wires (35) are guided and driven separately from one another in such a way that they are guided in their lengthwise direction relative to a cutting frame (14) and that they ...

The invention relates to a process for the preparation of positive or negative active mass of lead accumulators by using the active mass separated from production-refuse plates and/or the active-mass wastes produced during production. According to the invention when positive active mass is prepared then positive active mass, while when the negative active-mass is prepared then negative active-mass...

Joining of the prespun thread (4) of a first roll (2) to the prespun thread (3) of the second roll (1) of a ring spinning frame which uses threads of the carded type is achieved by means of a device (13) having a rotating jet of compressed gas, e.g. air. The threads are held by clamps (5, 9) on either side of the device (13). The latter comprises a cylindrical passage through which the thread (3) ...

An engine control system for a vehicle provided with an automatic transmission including an engine output control device for reducing an engine output in response to a shift operation of the automatic transmission, brake switch for detecting a braking operation of the vehicle, a restricting element for restricting the engine output control device from reducing the engine output when the braking op...

The specification discloses a bipolar battery and a method of making intercell connections between adjacent cells thereof including a container (100) having an intercell partition (108) a section (109) of which is thicker than the remainder of the partition (108). The thickened section (109) has an opening (114) therethrough receiving intercell connector links (124), which opening (114) has a mout...

Disclosed is a method for stopping and starting a reactor equipped with a heat exchanger, a catalyst settler, a catalyst filter and the like, which method is suitable for use in a process for the preparation of acrylamide by reacting acrylonitrile with water in the presence of a metallic copper-based catalyst used as a suspended bed. According to this method, various undesired phenomena which may ...

A sealed lead-acid battery is improved in manufacturability by providing a container (1) with a major side left open, and being sealed by a laminated sheet (3) heat-bonded to side edges of the opening after the battery components have been inserted. The laminated sheet (3) may include a metal layer to improve rigidity.

The machine for breaking up scrap material has a housing (1) with a hinged upper part (4). A rotor (6) mounted inside the housing can be rotated in either direction. The material is loaded into the lower inlet (15) and the rotor is rotated in the clockwise direction. The material is broken up by hammers (5) which are attached to the rotor and co-operate with the anvil (9). The broken up material i...

The object of the invention is to improve the handling of textile bobbins and textile-bobbin tubes, especially during the preparation of the textile bobbins. The object is achieved, according to the invention, in that the slip-on mandrel (5) of the pallet is longer than the textile-bobbin tube (2) and projects so far out of the textile-bobbin tube (2) that, with the textile bobbin (1) slipped on, ...

The invention relates to a front jaw having a housing, in the axial bore of which is accommodated a release spring which is supported at one end on a transverse wall and at its other end on a piston-like spring plate connected to a tension rod. The latter passes through the transverse wall and carries a control plate. In order, in this front jaw, to keep the prestress of the release spring constan...
