Title: Improvements in the manufacture of artificial silk
IPC: D01D10/04
Filed: 1930-03-21
Abstract: Artificial silk freshly produced by the centrifugal process in the form of a spun cake is washed and after-treated by subjecting it to an alternate or simultaneous spraying and dipping operation with the appropriate liquids.  For this purpose perforated tubular supports may be inserted through the cakes, and several cakes may be placed on the same support.  The supported cakes may be transported from one place of treatment to another by means of a conveyer.  Devices for causing rotation of the cakes about their longitudinal axis may be provided at the various places of treatment.  Preferably when several cakes are supported on the same tubular support, they are separated from each other by discs of resilient material such as rubber and are secured at the ends in order to avoid displacement of the threads during the treatment.  The treatment may be carried out so that each chemical treatment in which the cakes are freed from acid, bleached, or soaped is preceded or followed by washing.  The chemical treatment may be carried out by dipping, and the washing by spraying, or all the treatments may be carried out by dipping with simultaneous irrigating in the washing operation, or all the treatments may be conducted both by dipping and irrigating.

Title: Air flow separator
Inventor: BERNUTAT PAUL
IPC: B07B7/083
Filed: 1970-02-26
Abstract: 1,253,952. Centrifugal separators; upward current classifiers. P. BERNUTAT. 26 Feb., 1970 [1 March, 1969], No. 9311/70. Headings B2H and B2P. An air-flow separator for classifying particulate material comprises a separator chamber 1, a plurality of cyclones 6 distributed around, and in communication with, the chamber 1, and an impeller 2 mounted within the chamber and operable to discharge air and separated fine particles into the cyclones. The chamber 1 is annular, its inner wall being defined by a coaxial duct 16. The cyclones 6 are provided with inlet ducts 5 which are tangential to the impeller 2. Pivotable flaps 7 in the ducts 5 control the flow of air admitted to the cyclones. The cyclones are connected to the bottom of the chamber 1 via central pipes 10 and ducts 11. The velocity and direction of the air entering the chamber 1 from the cyclones may be varied by means of pivotable flaps 14 in the ducts 11 and adjustable vanes 12 at the exit of the ducts 11 respectively. The material to be classified is fed via a pneumatic conveyor duct 21 onto a distributor cone 20 and passes through openings 22 in the duct 16 into the chamber 1. As the material enters the chamber 1 it is met by an upward air vortex created by air induced by the impeller 2 through the ducts 11. Due to this vortex the material is distributed uniformly over the entire cross-section of the chamber and any agglomerates are broken down, the vortex also causing the coarse particles to separate towards the outer wall of the chamber. The coarse particles tall by gravity into a bottom hopper 17 while the fine particles are carried with the upward moving air through the impeller 2 and into the cyclones 6 where they are separated from the air and discharged through delivery spouts 9, the air being recirculated to the chamber 1 via the ducts 11. By setting the flaps 7 differently, the fines obtained from each cyclone may be different as regards grain structure.

Abstract: 831,543. Moulding air springs. FIRESTONE TIRE & RUBBER CO. March 21,1957 [Jan. 7, 1957], No. 9321/57. Class 87(2). [Also in Group XXXII] A number of plies of rubberised fabric are assembled to form a cylindrical body 23 at one end of which a bead 26 of substantially the same diameter is formed, the body is expanded by applying fluid pressure uniformly against the inside to expand the other end radially outwardly into contact with an external supporting surface 30, the expanded body is supported internally, and a bead is formed at the edge of the expanded portion. In the form shown two plies of rubberised fabric and an interior lining of neoprene are assembled upon a cylindrical building drum of the type used in pneumatic tyre manufacture, the bead 26 formed upon bead ring 24, and the cylindrical body then transferred to the apparatus shown for expanding the plies. The rigid supporting form of this apparatus is a frusto-conical shell 30 terminating in a flanged end 31 of diameter slightly smaller than that of the small bead 26 so that the semi-finished air spring can be dropped inside the shell with the bead resting upon the flange. The plies are expanded outwardly into contact with the inner surface of the shell 30 by an inflatable cylindrical bladder 33. The ends of the bladder are clamped between pairs of end plates 36 and 37 which are supported by a central hollow stud member 38, air under pressure entering the bladder through slots 40 in the wall of this member. The expanded air spring body is allowed to remain in contact with the shell 30 for a moment or two so that it will have a chance to set in the expanded condition, after which it is removed and fitted upon a conical drum where a second bead is formed at the opposite end to the first. The air spring is then removed and is ready for the moulding operation which itself forms no part of the invention. In this, the spring is simultaneously collapsed axially and expanded outwardly into contact with a multi-part mould which when closed defines a cavity which forms the air spring into its final shape.

Title: Two-reeler windrower
Inventor: GENG MANFRED
IPC: A01D78/10
Filed: 1991-05-10
Abstract: The invention is intended to improve the functioning of a two-rotor windrower which can be suspended on a tractor and the windrowing rotors of which are arranged in a staggered manner. The feature of such windrowers is that they do not pick up a strip of crop when they go round a bend in one direction. This defect is eliminated in that a two-wheeled undercarriage (1) is provided in such a way that one of its running wheels (6) is arranged in the interspace between the two windrowing rotors (10, 12). This position of the undercarriage (1) makes it possible to articulate the leading windrowing rotor (12) laterally on the undercarriage (1) and the trailing windrowing rotor (10) on the rear side of the undercarriage (1). This arrangement allows the windrowing rotors (10, 12) to be brought into an especially favourable transport position. <IMAGE>
