Abstract: A universal time clock that can be constructed in a very simple and inexpensive way and the globe of which is driven by the hour tube of a left-hand-rotating clockwork, a network of lines being marked on a bell-shaped top put over the globe. The lines extend from the center point of the bell-shaped top, along the shortest route, to the lower end of said bell-shaped top. For the adjusting of the network of lines, the bell-shaped top can be turned manually on the base.

Abstract: A drive system to raise and transport both print and correction ribbons on typewriters or like machines is powered by a single bidirectional stepping motor. In one direction of rotation the motor acts via a special action clutch to first drive mechanisms for raising a print ribbon and then to establish gear connections for driving mechanisms for transporting the print ribbon. In the other direction, the motor acts to establish gear connections for driving mechanisms for raising and transporting a correction ribbon.

Abstract: The disclosure concerns a continuous mixer for plastic material and of the type which permits control of the pressure on the material being mixed in the mixer by resisting the flow of mixed material displaced from the mixer when unmixed material is fed into the mixer. The resistance to the discharged flow is effected by one or more elements which engage the flow and which are movable.
