Title: Automatic shoe adjuster for drum brake - has screw spindle wedge for pressure block expansion during brake operation
Inventor: SCHROETER HANS O
IPC: F16D65/56
Filed: 1976-06-23
Abstract: Two brake shoes (16, 17) inside a brake drum has an automatic wear compensating mechanism, located between opposite shoe ends. Two wedge blocks (11, 12) are inside a guide tube (10) and whose outer ends are in contact with the brake shoes (41, 42). The expansion wedge (9) between the two wedge blocks is moved by a screw spindle (8) to which a ratchet nut is attached. The spindle nut is operated by a spring loaded switch bracket (3) which in turn receives its motion from the relative expansion movement of the two brake shoes. Hence any brake shoe wear is automatically compensated.

They can also be used as appetite suppressants for the treatment of pathological obseity. (I) also show antiserotonin activity in the rat uterus and rat paw oedema tests. They can therefore be used for treating migraine. Specific cpds. (I) include 2-(1-piperazinyl)-4-tert-butylthiazole. In an example, this is prepd. by refluxing 14.5 g. 1-piperazinyl-thiocarboxamide 1 hr. with 13.4 g. chloropinacoline in 150 ml. EtOH. The prod. is isolated as its dihydrochloride.
