Title: A new or improved systems or method of treating and apparatus for disentangling, or/and separating, or straightening, or rearranging fibres, in particular those to which oily lubricants are applied to facilitate the processes of manufacture, or recovery, or remanufacture
IPC: D01B3/04
Filed: 1920-05-15
Abstract: 167,837. Hollis, T., and Woodmansey, A. May 15, 1920. Openers &c. ; carding-engines.-Wool and other fibres to which oily lubricants are applied during their preparation for spinning are opened, carded, &c. in a bath of oil or oily emulsion. The oil &c. is contained in tanks G and H and is also sprayed on to the material at the feed and delivery ends through pipes D<3>, D<4>, D<5>, and V<1>. The material is fed in on an apron A and is carried by an apron B, under pressing-rollers C, C<1>, C<2> to carrying or drafting rollers E - - E<5>. It is then passed to a series of toothed rollers I, I<1>, I<2> co-operating with small toothed rollers M, N, O. These rollers work in compartments in a perforated inner shell G<a> arranged to break up any currents set up in the oil &c. Two further rollers J, K co-operating with a series of small toothed rollers P, and a series of plain rollers Q respectively are arranged above the surface of the bath. The roller K acts as a doffer and delivers the material to a pair of rollers R, R' and an apron S whence it is passed by an apron T to squeezing rollers U, U<1> and the delivery apron A<1>. The rollers R, R<1>, squeezing rollers, and delivery apron are arranged above the tank H which is provided with a perforated grid Ha to catch detached fibres. The rollers I, I<1>, I<2> are supported in a frame Z pivoted to the axis W of the roller J. The small rollers above the axes of these rollers are carried by brackets secured to arches mounted on a frame Y, which is also pivoted on the axis W and supported by the axes of the larger rollers. A second frame Y<1>, which can be secured to the frame Y, carries arches on which are mounted brackets to support the small rollers below the axes of the rollers I, I<1>, I<2>. The frame Z normally rests on ribs secured to sides of the tanks, but can be raised to lift all the rollers out of the liquid. The main drive is on the shaft 1 of the lower squeezing- roller, and the other parts are driven from this shaft by suitable spur and chain gearing. The liquid in the tanks may be heated by steam pipes. The spray pipe V<1> may supply clean lubricating liquid to the material. The number and arrangement of the working-rollers may be varied to suit the material under treatment. The material may be passed through a series of graded machines and be delivered as a web or lap, or as a sliver to be wound in a ball or coiled in a can. Endless travelling aprons, or series of bars, which may be provided with teeth, can be substituted for the rollers.

Patent GB-825620-A (GB)
Title: Improvements in or relating to methods of treating silicon-iron alloys
IPC: F02M25/022
Filed: 1958-04-29
Abstract: In the method of heat treating silicon iron alloys as described in the parent Specification, between the cold deformations there are intervening heat treatments at least one of which is carried out at a temperature exceeding 950 DEG C.  (1000-1350 DEG C.).  This one intervening heat treatment may be carried out either in a vacuum with a pressure of 10-2-10-4 mm. mercury, or in an atmosphere containing at least 50% hydrogen, possibly immediately before the last cold deformation but preferably immediately before the penultimate cold deformation.  The percentage reduction of the section of the workpiece produced by the last cold deformation may be greater than that produced by the penultimate cold deformation.  The final heat treatment may be preceded by an additional heat treatment the duration (at least 10 minutes) and temperature (500-800 DEG C.) of which are such that more than 90% complete primary recrystallization takes place with less than 10% secondary recrystallization with cubic texture.  This additional heat treatment may be carried out in an atmosphere which is non-oxidizing, or only gently oxidizing, or containing hydrogen, and the workpiece may or may not be cooled to room temperature between the additional and final heat treatments.
