Title: Device for indicating the correctness and uniformity of the twist imparted to a sliver of fibrous material
IPC: G01N33/36
Filed: 1928-09-04
Abstract: 298,222. Lactsch, J. P., and Litty, P. Oct. 7, 1927, [Convention date]. Testing yarns.-The correctness of the number of twists imparted to a roving to obtain the requisite tensile strength to resist the strains of spinning and yet to allow the roving to be drawn, and the uniformity of such twists over a continuous length of roving, are determined by a device comprising two pairs of rollers 5, 5<a>, 6, 6<a> between which the roving is led over a hook 1 on an arm 2 counterweighted at 4 and provided with a pointer 3 moving over a scale 8. The rollers 6, 6<a> rotate faster than the rollers 5, 5<a> by a predetermined amount to provide the tension to drawn the hook 1 downwards. The weight is adjusted so that the requisite force is applied and when a weak place passes over the hook the sliver yields. To prevent it being broken the movement of the weighted arm is checked by a pawl 7 engaging a rotating disc 9 and the arm 2 is returned to the normal position. The pawl may be operated by a rotating screw. The movements of the pointer 3 may be read or continuously marked on a paper strip, and afford an indication of the uniformity of the twist of the sliver. The average position of the pointer affords an indication as to whether the twist is correct, or insufficient, or too hard.

Abstract: 922,470. Rotary motors and pumps. J. R. MOTTERSHEAD. July 13, 1961 [July 26, 1960], No. 25909/60. Class 110 (2). [Also in Group XXIX] A variable hydraulic power transmission comprises pump and motor rotors 10, 11 of the radial vane type having a fixed eccentricity relative to each other and operating in a drum 13 which is divided by a stator 14 into pump and motor compartments, the stator and drum having a common axis disposed, and adjustable in, the common diametral plane of the rotors so as to vary the eccentricity of the stator and drum relative to the rotors and the output speed of the motor rotor. The pump and motor rotors 10, 11 are mounted on input and output shafts 21, 22, supported in bearings 19, 20 in an outer casing 18. The rotors have radial vanes 31, 32 maintained by rings 33, 34 in engagement with the drum 13 which is rotatably supported in bearings 15 in a yoke 16 movable in slideways 17 on the easing 18 in the common diametral plane to vary the output speed of the transmission, the arrangement permitting infinitely variable adjustment from an overdrive in a forward direction to a low-speed reverse drive. The stator, which is prevented from rotating by a block 23 slidable in a guide 24 in the stator and itself prevented from rotating by spigots 25 supported in bearings 27, 28 in the ends of the shafts 21, 22, has arcuate passages 35, 36 separated by parts 37, 38 to permit flow of fluid from the pump to the motor and vice versa, one of the parts 37 being slidably urged by a spring 48 into engagement with the drum 13 to take up wear. The stator may be movable against the spring 48 to lift the part 38 from the drum and interconnect the passages 35, 36 to provide a freewheel operation in which the motor rotor 11 can move independently of the pump rotor. To compensate for the varying volumes of the spaces between the vanes as the spaces approach and leave the parts 37, 38, ports 39 in the stator parts 37, 38 are interconnected by conduits 40 to connect the spaces in the pump adjacent the parts 37, 38 together and the spaces in the motor adjacent the parts together. The transmission is filled with fluid from a header tank connected to the casing 18, passages 41 and spring and centrifugallycontrolled valves 42 connecting the interior of the casing with the working spaces of the pump and, by way of the passages 35, 36, the working spaces of the motor. Passages controlled by a shuttle valve 45 responsive to the pressure in the passages 35, 36 also supply fluid to the inner ends of the vanes to balance the fluid pressure acting on the vanes.
