Title: Method and apparatus for splicing yarn
IPC: B65H69/06
Filed: 1967-06-17
Abstract: Multifilament yarns which may be used in making cord fabrics to reinforce tyres are spliced together by laying the two yams in superposed overlapping opposed relation in a laterallyconfining, longitudinally-unconfining region, injecting a wedge of compressed gas vertically through the yarns at an intermediate point in the region to separate the yarns into two groups of filaments, with the gas passing through and along the yarns in both directions to intertwine the filaments on each side of the intermediate point. The gas may be injected into the region at more than one point, and/or each yarn may be divided into two ends with one end of one yarn being spliced to an end of the other yarn at a point axially spaced from a point where the other two ends are spliced. One apparatus described comprises a baseplate having a removable insert formed with a splicing chamber connected to the gas inlet in the plate and having an opening at each end in which the yarns are held and through which the gas leaves the chamber. A lid with a sealing gasket and two gas escaping holes is hinged to the base-plate. Another apparatus described, has two splicing chambers arranged side by side with the air inlets staggered and formed partly in the base-plate and partly in the lid.

Title: Improvements in or relating to washing machines
IPC: D06F35/00
Filed: 1971-07-06
Abstract: In a method of using a washing and spin drying machine comprising a resiliently mounted tub accommodating a drum which is rotatable about a horizontal spindle, an electric motor for driving the drum at a washing speed and at a spin drying speed, a constant ratio transmission between the motor and the drum spindle, and water supply and drain means, after the washing operation (e.g. 50 r.p.m.) when the motor is changed over to the spin drying speed and the drum is accelerated with the tub still full of water an intermediate speed (e.g. 70 r.p.m.) is attained at which the torque delivered to the spindle and the. reaction torque are balanced until the water in the tub has been driven into rotation when the reaction torque is reduced and the drum acceleration continues. The drum accelerates through the critical speed range of 100 to 160 rpm to a second intermediate speed (e.g. 200 to 300 r.p.m.) when the drum may be balanced by introducing water into chambers secured to the drum. On draining of the water within the drum, the drum accelerates finally to the spin drying speed (e.g. 1000 r.p.m.). Although the pump may be switched on at the beginning of the spin drying cycle or when either of the intermediate speeds is attained, due to a time lag in its effective operation, the tub is not drained before the second intermediate speed is attained. As shown the tub is suspended by helical springs and is provided with dampers. The motor may be an AC motor with two windings or may be a permanent-magnet induction direct current motor fed by an electronic speed control device. The latter motor may be connected in series with a heater for the tub and braking may be effected by causing the motor to act as a generator for the heater.
