IPC: D04B15/90
Filed: 1935-12-06
Abstract: 447,664. Knitting. STOLL, H., and STOLL, R., (trading as REUTLINGER STRICK. MASCHINENFABRIK H. STOLL & CO.), Reutlingen, Wurtemberg, Germany. Dec. 6, 1935, No. 33867. Convention date, Dec. 18, 1934. [Class 74 (ii)] In a take-up mechanism for flat machines, in which several light pressure rollers, mounted in pairs on levers, co-operate with a single take-up roller, the ratchet wheel 7, rotating the takeup roller 6, is freely mounted on a gudgeon pin 5, and is driven round by a single spring-pressed pawl 13, reverse rotation being normally prevented by the wedging of a spring-pressed roller 11 in an angular recess, formed on a circular flange 10, fixed to the pin 5, and housed within the flanged periphery of the wheel 7. The pawl 13 is carried by a bell-crank lever 15, 16, the driving and return strokes being imparted by a cam or eccentric 20, and a spring 18, respectively. On sufficiently lifting by hand the arm 15 of the bell-crank lever, a bluff 22 is caused to render the pawl inoperative, whilst, simultaneously, the nose 28 of a lever 27 is made to retract the roller 11, so that the take-up roller can be rotated in either direction, Each pair of pressure rollers 30, 30<1> is carried by a bifurcated lever 32, freely mounted on a carrier shaft 33 having a keyway 34. Housed in the bifurcation is a lever 36, slidably keyed to the shaft. The rollers are adjustably pressed against the take-up roller by a screw 38 which is carried in the lever 36, and acts on a spring 39 carried in the lever 32. The whole series of pressure rollers is swung to and from operative position by rotating the shaft 33, the positions being located by a pin 43 and notches 41. The keyway 34, terminates at each end of the shaft in a gap 35, so that one or more pairs of pressure rollers may be rendered inoperative by sliding them along the shaft until the key 37 on the lever 36, reaches a gap.

Title: Improvements in or relating to the manufacture of anhydrous aluminium chloride
IPC: C01F7/58
Filed: 1959-10-13
Abstract: A continuous process for the production of high-purity aluminium chloride comprises continously passing chlorine into the foot of a vertical reaction vessel packed with a bed consisting of separate lumps of aluminium metal, continuously introducing lumps of aluminium into the top of the vessel so that impure aluminium chloride vapour formed towards the foot of the vessel is purified by fractionation as it rises through the bed, continuously removing the purified vapour from above the bed and condensing it within, but out of contact with the walls of, a separate chamber, the whole process being effected with exclusion of water vapour.  The upper region of the reaction vessel may be externally cooled.  The reaction may be initiated by preheating the lower region to 400 DEG C.-600 DEG C., the remainder of the vessel being maintained at nearly 200 DEG C.  The aluminium may be supported on a grating such that ashes and impurities may collect below the grating and be periodically removed.  Any molten aluminium will collect underneath the grating and react with incoming chlorine, thereby providing in part an automatic temperature control. Specification 678,563 is referred to.
