Abstract: 951,197. Apparatus for treating bands of fibres. FLEISSNER G.m.b.H. June 15,1960 [June 15,1959; Oct.30, 1959], No. 21021/60. Heading D1L. Bands of fibres are treated by a method comprising the steps of passing the bands through a guide means which rotates or thrusts the bands and separates any bands which have run together, passing the bands into a treatment bath through the upper surface of the bath, and effecting at least two successive squeezing actions on the bands while they are immersed in the bath, whereupon the bands pass out of the bath through the upper surface of the bath. Referring to the drawings bands of fibres 8 are fed over guide roll 12 (Figs. 3 and 4) to band guide means 1, then to feed roll pair 2 and into bath 9 in which large roll 3 is partly immersed in water, while smaller rolls 4 provide two squeezing areas on roll 3 where the bands are subjected to a squeezing action. The bands 8 then leave the bath 9 to presser rolls 6, 6a via guide roll 5 and then to deflector roll 7 which prevents coil formation. The band guide means 1 comprises a staggered row of guide elements la (see Fig. 2) adjustably mounted on a retaining plate 11. Referring to Fig. 2 the bands are in the plane of the drawing and moving in the plane of the drawing from the bottom upwards. The bands contact one of the sides of the three-sided elements la and are turned over on to their sides i.e. rotated through 90 degrees so that they lie in a plane at right angles to the plane of the drawing. A modification is shown in which the large roll 3 is completely immersed and rolls 4 partly immersed and another in which the bands 8 are passed over completely immersed roll 3 and squeezed four times.

Abstract: 206,574. Amberton, R. Aug. 8, 1922. Controllers with auxiliary switches.-In a rheostatic motor-starter fitted with two electromagnetic line contactors, one in each supply line, the circuit whereby the line-contactor closing magnets 35, 36 are energized passes through the main rheostat contacts 22, the movable brush 19, and an auxiliary lost motion contact arm 25 displaced by the initial movement of a follow-up handle 14, which is separate from the brushcarrying arm 18. Closure of the line-contactors completes a hold-on circuit independent of the rheostat contacts. When the handle is released on any intermediate stud, the lost motion contact opens and the motion is completely disconnected from the line. At the full-on position of the brush, it displaces, through an insulating button 46, a further auxiliary contact arm 41 which makes a hold-on circuit for the line-contactor magnets independently of the lost-motion contact. Provision is made for manually displacing a contact 42 so as to break the final hold-on circuit when desired. After the line-contactors have been opened, they cannot be re-closed except by returning the rheostat brush arm to its initial position so as to complete a preliminary circuit through contacts 31, 33, Specifications 28527/13, 151,206, and 188,975 are referred to.

Title: Improvements in or relating to the isomerization of paraffin hydrocarbons
IPC: C07C5/27
Filed: 1943-12-23
Abstract: A pool of liquid aluminium chloride-hydrocarbon complex of substantially greater density that the hydrocarbon feed is maintained in a conversion zone up to a level spaced from the top thereof, a liquid paraffin feed is dispersed into said pool at a low level and passes upwardly under isomerization conditions in the presence of hydrogen chloride, entrained liquid complex is separated from hydrocarbons in a first separation zone, forming part of the conversion zone above the pool, hydrocarbons are withdrawn, cooled, and introduced to a second separating zone outside the conversion zone where residual complex is separated, hydrogen chloride then being removed and the hydrocarbons neutralized.  The hydrocarbon feed should be of narrow boiling range and may be obtained from natural sources or hydrogenation of organic materials or carbon monoxide. The catalyst complex is prepared from paraffin, e.g. the isomerization feed or isoparaffins, from mixtures of paraffin and naphthenes or from olefins.  Reaction with the aluminium chloride in presence of hydrogen chloride is effected at 100-300 DEG  F. or more. The preferred complex has a heat of hydrolysis of 60-75 Cals. per gram atom of active aluminium and contains 3-8 mols of aluminium chloride for each double bond per mol. of oil obtained on hydrolysis. A column of complex of at least 5, preferably 20-30 feet or more, is used.  Make-up aluminium chloride is added as a solution in light hydrocarbons or a paste in complex.  Side reactions are inhibited especially in pentane isomerization, by addition to the feed of .02-2 per cent or more by volume of aromatic hydrocarbons, especially benzene, or 1-15 per cent or more of naphthenes or both.  A light naphtha may be treated in a fractionation system, if desired, with the products, to separate n-butane, pentane, hexane, &c., fractions which pass to separate isomerizers after picking up make-up catalyst, hydrogen chloride, and inhibitor.  Isomerizers in series containing catalysts of increasing activity may be used for each fraction.  A continuous hydrocarbon phase separates at the top of the column of complex and passes to a separator at about atmospheric temperature and 250-350 p.s.i.  The lower complex layer is recycled, gases are vented, and product passes to hydrogen chloride stripper operating at, say, 130 and 225 DEG  F. at top and bottom respectively, and slightly above reactor pressure.  It is then washed with alkali, water, and fractionated.  Pentane and butane or hexanes and pentane may be isomerized together.  Free hydrogen is added in the case of hexane isomerization.  Higher boiling hydrocarbons may be treated with less active catalyst to isomerize naphthenes and to produce lower boiling hydrocarbons for subsequent isomerization. Products from the isomerizers may be treated to remove aluminium chloride with complex of low aluminium chloride content or with hydrocarbons forming a complex therewith.  Specifications 539,297, 556,481, 559,426, 583,116 and 598,949 are referred to.
