Patent GB-394966-A (GB)
Title: A new or improved machine for mercerizing and neutralizing textile skeins
IPC: D06B3/08
Filed: 1931-12-22
Abstract: In a combined mercerizing and neutralizing machine, the neutralizing mechanism is coupled with the usual mercerizing mechanism so that the driving gears of the latter rotate the neutralizing skein rollers in alternate directions simultaneously with the mercerizing skein rollers, and also drive a cam shaft which controls the successive operations of acidifying, washing, rinsing and drying one set of skeins whilst the succeeding set of skeins is being mercerized. Skeins are removed by hand from the mercerizing rollers 7, 7a and placed over the loose porcelain roller 6 and fast ebonite roller 4, the latter being driven from the mercerizing skein roller 7; fresh skeins are then placed on the mercerizing rollers.  The machine is restarted, the cam shaft 1 first causes the <PICT:0394966/IV/1> acid bath 9 to be raised and the pressure roller 5 to be brought into contact with the skein, as shown.  When the hank has been acidified, the acid bath 9 is lowered and the empty water trough 15, pivoted at 23, is swung into a vertical position by levers 17a, 18, pivoted at 19, and actuated by a cam 20 mounted on the cam shaft 1.  Another cam then actuates a valve 42 and admits water to the sprinkler tubes 48 which washes the skein and drains away.  A valve in the drain-pipe of the water trough 15 is next closed, and the trough fills with water from the sprinklers 48, the sprinkler valve 42 is then closed.  The skeins, still in motion, are rinsed, the water trough is emptied and swung clear of the skeins, which are squeezed and partly dried by the rollers 4, 5.  The presser roller 5 is finally moved away from the skeins, the machine stopped and the cycle of operations repeated. Specification 327,399, [Class 15 (i), Dyeing &c., Apparatus for], is referred to.

Abstract: 1,079,542. Measuring cohesion. KETJEN CARBON, NAAMLOZE VEMNOOTSCHAP. Sept. 4, 1964 [Sept. 10, 1963], No. 36306/64. Heading G1S. The cohesion of two plies of rubber or rubberlike material is measured by clamping one end of each of two plies on two wheels, clamping the plies together and then separating them after an adjustable time by turning the wheels with a uniform velocity. The apparatus comprises two motor driven wheels 3, 5 on which are clamped two plies of rubber covered fabric, an apertured polyester film 13 for defining the area of contact between the plies to be tested, means for governing the compression force, the compression and relaxation time, a differential gearing system 2 situated in the driving axle 16 between the motor and one of the driven wheels 3, a system to detect the movement of the spider shaft 14, a system for compensating the detected movement, and a system to record the compensation force, which is a measure of the 'cohesion'. The apparatus uses the principle that the momentum of rotation of the driving axle is transferred to the spider shaft and that changes in this momentum caused by the cohesion of the plies is determined by measuring the force necessary to keep the spider shaft in its place. The plies are compressed by clamps 12 around the aperture in the polyester film to record a zero level. After a set time the pressure is released, two small rollers 11 remaining in position to give a fixed separation position. After a fixed relaxation time the motor driven wheels are started and the fluctuation in speed of the axle 16 caused by the cohesion of the plies results in the movement of the axle 14 and of a block 23 connected thereto. The small vertical displacements of the block 23 warp leaf springs 27 causing a coupling pin 28 to contact one of two terminals 31, 32. This contact is relayed to the servomotor 18 to rotate a wheel 21 in one of two directions to restore balance to the axle 14 by adjusting the length of the spring 6 and thus stop the servomotor. The movement of the wheel 21 is linearly registered on paper 46 by the rotation of a wheel 42 with the axle of the servomotor 18.
