The strips 35 have projecting teeth on one side thereof for positive mechanical engagement with wheels 43, Figs. 4 and 7, coaxial with desired value potentiometers 44, Fig. 4. Each wheel 43 engages a transmission wheel 45 rotationally fast with a dial wheel 46 and a hand positioning wheel 47, Figs. 1 and 2. Upon angular adjustment of the potentiometers 44 a control pulse is transmitted through lines 48 to motors 27 so that these run and adjust the elements 22 to regulate oil pumps 16, 19 through levers 20. The potentiometers 44 are monitored in an electronic follow-up control system, Fig. 11 (not shown), by actual-value potentiometers 49 mounted coaxially on spindles 23 carrying the elements 22. The elements 22 are locked in position when the conformity of position of the potentiometers 44, 49 is attained and the machine may be switched on by a lever 31. The plate 32 is exchanged for each different carpet fabric to be sheared. (For Figures see next page)

Abstract: 749,402. Stretching; straightening. BIGWOOD & SON, Ltd., J. Dec. 7, 1954 [Dec. 7, 1953], No. 34012/53. Class 83 (4). A machine for stretching metal sheets having two opposed sheet-gripping devices relatively movable to stretch the sheet has mounted in front of the opening of the jaws of each gripping device a pair of rollers adapted to advance the sheet to insert its edge between the jaws. Two gripping devices 10, on wheeled carriages 11, grip the opposite edges of a sheet of metal 14 and on movement of one gripping device away from the other, by hydraulically operated means, the sheet 14 is stretched therebetween. To insert the edges of the sheet between jaws 12 of each gripping device, prior to stretching, the edge is inserted between upper and lower rollers 15, 16 mounted in front of the jaw opening of the gripping device, the lower roller 16 having been suitably adjusted vertically in accordance with the thickness of the sheet. Hydraulic units 19, the rods 22 of which are connected by a pin 23 to a beam 20 extending the length of the rollers, are then actuated to move the beam 20 downwards, thus moving the upper roller 15, which is journalled in the ends of the beam and is backed by bearings 21 along its length, down onto the sheet 14. The roller 15 is then rotated, through gearing 26, 27 by a handle 29 or by power means, to feed the sheet edge to the jaws 12 which then move to grip the edge and the hydraulic pressure on the roller 15 is released. The roller 15 may be rockable about a horizontal axis to adjust itself to unevenness of the sheet across its width. Specification 614,186 is referred to.

Title: Improvements in the production of crimped yarns from polyvinyl alcohol
IPC: D01D5/22
Filed: 1960-10-06
Abstract: Crimped yarns are produced by subjecting a yarn of an un-acetalised polyvinyl alcohol to the successive action of aqueous alkali metal hydroxide solutions of increasing alkalinity until a crimp has developed in the yarn.
