Title: Improvements relating to apparatus for testing friction between surfaces
IPC: G01N19/02
Filed: 1922-03-17
Abstract: 202,346. Elverson, A. J. H. March 17, 1922. Testing friction and viscosity.-The friction between two surfaces is measured by a stroboscopic method in which the surfaces, dry or lubricated, are rotated or reciprocated together one driving the other, the point of slip being indicatel by one surface departing from an apparently stationary position. In the form shown, the driving shaft A carries on a head C a disc D which engages and drives a disc E carried on a head F on a shaft G, the second disc being pressed against the first disc by a spring H the compression of which can be varied by a head J mounted upon the screwed shaft g. Ball-thrustbearings t, T are provided as shown and the driven shaft G may be connected to a dynamometer. The shaft A is coupled up to a driving motor and speed indicator, and preferably, is connected to a pump for supplying lubricant to the surfaces under test. The shaft carries a stroboscopic instrument B preferably operating make and break devices in electric circuit through a condenser and transformer device with an electron discharge lamp which causes flashes to illuminate the discs either synchronously with the driving disc, or at a small difference in time period, so that the latter appears to be stationary or rotating slowly. The discs D, E are interchangeable with other discs. The lubricant is introduced through a channel a in the bearing P and an axial channel to a channel d in the disc D from which it issues through holes e to the surfaces in contact. Lubricants may be tested in this way and measurements of comparative viscosity deduced.

Title: Improvements in or relating to creel-arrangements for the feeding of textile materials
IPC: D04B15/38
Filed: 1929-03-14
Abstract: 331,202. British Celanese, Ltd., Welch, S. A., Guyler, A. F., Ashby, J. T., and Boaler, W. H, March 14, 1929. Creel arrangements; rollers and roller heads. - In means for drawing yarns and threads from bobbins or spools and feeding them at a uniform tension, the yarns &c. are drawn from bobbins or spools 3 and are passed substantially without tension to feeding rollers 7 which forward them at a rate controlled by their tension after they have left the feeding rollers, the stress of pulling the threads from the bobbins being thus removed from the rollers 7. In the form shown, a bar 5 oscillates and pulls the threads into contact with the surface of rollers 6, the speed of which is greater than the rate of consumption of each thread, thus causing an accumulation of thread during the outward movement of the bar 5, which is passed to the rollers 7 during the return movement. The bar may be driven by a cam and spring &c. and may have a rapid drawing movement and a slow return movement. A series of tension bars 8 are preferably included to reduce the tendency of the thread to be drawn back through the rollers 7 during the drawing movement of the bar 5. The rollers 7 which may have corrugated surfaces, may be positively driven by a variable speed friction clutch controlled by the movement of a tension bar 12, or they may be driven by the pull of the threads passing through them and a friction brake applied to the rollers, the friction being varied by the bar 12. A stop motion may be fitted to operate on the rollers 7. The drawoff device preferably operates at each course in a warp-knitting machine.
