Disclosed is a method of desulfurization of unsaturated hydrocarbons or hydrocarbons containing unsaturated hydrocarbons. The method of desulfurization of the invention is characterized by desulfurizing unsaturated hydrocarbons or hydrocarbons containing unsaturated hydrocarbons in the presence or absence of hydrogen, by using a copper-zinc desulfurizing agent prepared by co-precipitation method. ...

The rotor (1) which is driven by a shaft (2) carries a crown wheel with webs parallel to the axis. A cutting box (4) has two cutters which are also parallel to the axis surrounds the rotor. A casing (5) which encloses the cutter box has an inlet for the supply of shavings as well as an outlet for the finished cut product. Sealing parts close the chinks of the slot between the rotor and the cutter ...

In the emerising machine, easy emery bar (2) to brush against the fabric pile (10) is formed as a spiral round the emerising roller (1).Pref. two or more emery bars (2) are fitted to the roller (1), parallel to each other in spirals, forming a multi-screw structure. The outer edge (3) of each emery bar (2) is directly roughened, or treated with an emery coating (9). The radial outer edge (3) of th...

A lock arrangement for a knitting machine, which comprises knitting implements (3, 3a) mounted to slide in a longitudinal direction (w), with working and control butts (6, 6a; 7, 7a). The lock arrangement (8) includes a take-down lock part (61) associated with the control butts (7, 7a), slidable in the longitudinal direction (w) and each adjustable into an advanced and a retracted position, these ...

In a method and apparatus for limiting the speed of motor vehicles, in cases where a speed signal is not available, engine cut-off is not rigidly activated upon exceeding a constant rotational speed threshold. Rather, a variable rotational speed threshold is determined which takes into account instantaneous or previous driving states, thereby being responsive to instantaneous or previous reactions...

A hydraulic adjusting device for rotating a camshaft relative to its drive wheel which includes a coupling member, which cooperates with the drive wheel and with the camshaft via a pair of gear tooth systems, at least one of which is a helical gear. The coupling member is connected to an actuator, which is embodied as a single-acting cylinder. This singleacting cylinder is acted upon by pressure t...
