Abstract: The letterpress printing machine includes an impression cylinder (8), at least one inking device (11, 12, 13) with an inking train comprising inking rollers (25, 26, 28) and at least one letterpress form cylinder (14, 15, 16) inked by said at least one inking device (11, 12, 13). The at least one letterpress form cylinder (14, 15, 16) is driven by first drive means (30), whereas the at least one inking device (11, 12, 13) is driven by second drive means (31, 32, 33), the second drive means (31, 32, 33) being mechanically independent from the first drive means (30). A control unit is coupled to the second drive means (31, 32, 33) to adjust a circumferential speed of the inking rollers (25, 26, 28) with respect to a circumferential speed of the letterpress form cylinder (14, 15, 16) so as to adjust deposition of ink by the inking device (11, 12, 13) on the letterpress form cylinder (14, 15, 16).

Abstract: Isocyanate-derived foams are prepared from an isocyanate, catalyst, blowing agent, foam stabilizing surfactant and at least two active hydrogen-containing compounds wherein one of the active hydrogen-containing compounds is an alkylene oxide polymer having an equivalent of at least 300 and being composed of at least about 10 weight percent, based on a total weight of the polymerized alkylene oxide in the polymer, of a polymerized ethylene oxide.

Abstract: A pushbutton-operated circuit breaker has a thermal release and an independent trip which can be mannually operated to trip the circuit breaker from the "on" position to the "off" position by depressing the pushbutton. A slide is provided within the switch which, when contacted by the pushbutton, forces a bimetallic spring to bend and release the switch. The slide is movable within the switch such that it is outside of the path of movement of the pushbutton when the circuit breaker is being switched from the "off" to the "on" position, but is engageable by the pushbutton when in the "on" position.

Abstract: An electrohydraulic drawing or hoisting apparatus for the pulling or lifting and lowering of loads, in which a load lifting member, hydraulic fluid tank, electric motor, pump, and control unit are all mounted within a single compact unit which is rigidly connected to one end of a cylinder piston unit. A control handle is connected to the hydraulic control unit so that the directions of displacement of the handle and the resulting motion of the load lifting member coincide substantially. The speed of the piston in both directions is continuously variable as a function of the displacement of the control handle. The piston's speed in at least one direction of motion, moreover, is controlled by influencing the pump delivery through displacement of the control handle.
