[Also in Division H1] To adjust the action of one tripping member, e.g. a bimetallic strip 2 without effecting the action of a second tripping member 7, e.g. of an electromagnetic tripping device, a pivoted lever 10 is mounted so that it, together with its axis 11, may be turned about a fixed axis 13. At, or in the vicinity of the axis 13, the second tripping member 7 and a transmission lever 16 bear on the lever 10 when the lever 16 is about to release a latch (not shown), e.g. of a circuitbreaker. The axis 13 is the pivotal axis of a lever 12 on which the lever 10 is pivoted. The lever 12 is biased by a spring 20 against an adjustable abutment 19. The lever 16 bears on a surface 15 on the lever 10 and when electromagnetic tripping occurs, the end of the lever 16 slips off the end of the lever 10 so that the armature 5 may serve as a striker for separating the circuit-breaker contacts after the latch has been released by the end 18 of the lever 16.

Title: Continuous dyeing of textile materials
IPC: D06B19/00
Filed: 1976-12-09
Abstract: In a process for pad-dyeing textile material in sheet form on a pad-mangle having a short-liquor trough using aqueous padding liquors which in addition to dyeing assistants contain dyes which develop an affinity for the fibre only on heating of the padding liquor to temperatures above 60 DEG C, the cold padding liquor is passed on the way to the pad-mangle trough through a continuous heater, raising it to the treatment temperature which is above 60 DEG C. A short-liquor (economy) pad-mangle usable for this purpose has a continuous heater situated in the liquor feed line between the reservoir tank and the short-liquor trough and is provided with a means for setting the temperature of the padding liquor flowing out of the continuous heater into the short-liquor trough. The process is of special relevance for the continuous pad-dyeing of cotton textiles, since it makes it possible, despite the single-stage method of operation, to achieve the same success as requires a multi-stage treatment in the case of conventional pigment padding processes.
