Title: Improvements in and relating to motor driven spinning centrifuges
IPC: H02K7/102
Filed: 1930-07-15
Abstract: Driving.-The can of a spinning centrifuge is driven by an electric motor connected directly to the supply without a switch and designed to carry the full short-circuit current.  The apparatus is brought to rest by a brake acting on the shaft of the motor or of the spinning can.  The spinning can may be covered with leather and braked by hand.  The motor is thus braked under full current and at full voltage.

Title: Method of and apparatus for the wet or dry treatment of textile materials
Inventor: CHIPALKATTI VASANT BHIMRAO
IPC: D06B19/00
Filed: 1958-06-02
Abstract: Textile materials are treated by passing them through a column of solid discrete particles fluidized by means of the treating fluid, which is made to impinge on both sides of the material substantially normally to the plane of the material by means of pressure nozzles or slits.  The textile material is a web, yarn or fabric of <PICT:0889211/IV (c)/1> natural or artificial fibrous material.  As shown, the textile material 1 passes around guide rollers 2, 3 and 4, so that it passes downwards through one limb 5a, and upwards through the other limb 5b of a U-shaped column.  This column contains a bed of solid discrete particles, e.g. of silica, sand, glass beads or porcelain beads, which are kept in a fluidized state by supplying fluidizing medium through the banks of nozzles 7 and 8, the nozzles 8 being mounted in a central partition in the form of a hollow chamber 6.  9 is the fluid storage tank, 10 is the fluid circulation pump, and 11 a heat exchanger.  Fluid and also any solid particles leaving the bed may be recirculated.  The fluidizing medium may be a solution of dye, scouring liquors, bleaching liquors, or oxidising liquors, or may be a gas, e.g. air or super-heated steam.  The fluid jets from the nozzles preferably impinge with the same velocity on both sides of the textile material.  The examples describe the dyeing of cotton fabrics by the method of the invention.

Abstract: 659,473. Yarn &c. twisting machines. UNITED STATES RUBBER CO. Aug. 30. 1949, No. 22500. Convention date, Oct. 28. 1948.'[Class 120(ii)] A machine for twisting together two strands to form a two-ply strand, of the kind in which one strand is ballooned about the let-off package of the other prior to twisting together has means for positively feeding at identical rates the individual strands to the plying position. In one embodiment, two twisting units are mounted on a single frame, each unit being independently driven by a motor 95. In each unit one strand x is led from a package A through an arm 26 operating a brake 24 to control the let-off tension, to feed rolls 36, 37. From the rolls 36, 37 it passes via a guide P to a flyer 53 and thence into an aperture h in the revolving flyer shaft to be twisted about the other strand y. The strand y passes from its package B via tension controlling means, similar to that described for the strand x, to feed rolls 54, 55 and through an aperture in a support 51 for the package B, into the flyer shaft 41. The two-ply strand z is led round a weighted roller 71 to a series of conical take-up rolls 79 the take-up tension being controlled by the shifting of the strand laterally along the rolls in response to up or down movements of the weights 74. The strand z. is distributed on the take-up package C by a traverse roll 91. The feed, takeup and traverse rolls and the flyer shaft are all driven by the motor 95. The feed rolls 54, 55 are carried by the support 51 which is held stationary by magnets on a ring 66 secured thereto coacting with magnets 70 on a fixed ring 68, the strand x ballooning between the two rings. In an alternative embodiment, the packages A, B may be positively driven to impart twists to the separate strands the tension control devices on the packages A, B being replaced by flyer arms. U.S.A.
