Title: Textile combing machine
IPC: D01G19/16
Filed: 1950-12-20
Abstract: 703,996. Textile combing machines. HAMBURGER WOLLKAMMEREI AKT.- GES'. Dec. 20, 1950 [Dec. 24, 1949], No. 31049/50. Class 120(1) In a combing machine for the production of tops or combed fibres of different staple lengths, an endless pin band 1, into which fibre tufts drawn from one or more feed devices and thus combed out at one end are dabbed by means of nipper elements, is guided over reversing rollers some or all of which constitute circular combs having pins which combine with the band in the region of reversal of the direction of travel thereof to form a strengthened pin field to which the fibre tufts carried by the band are delivered to complete the combing process. During one cycle of operation of the apparatus shown, a rocking lever 11 in position y commences to move in the direction,of the arrow x and driven cylinders 12 feed a portion of uncombed sliver towards a feed comb 14: a top comb 17 is lifted from the position shown and a catch 18 moves over a catch 19 on the top nipper element 4 and approximately at the same time a catch 20 on the comb 14 engages a catch 21 on the lower nipper element 5. When the lever 11 completes its movement the elements 4, 5, are closed under the action of eccentric discs 9, 10, links 6, 7, and catches 21, 20 engage so lifting the comb 14. The comb 17 may be held up by a pawl arrangement. until it can bear by its catch. 22 on a catch 23. When the lever 11 reverses, the catches 20, 21 disengage so that the combs 14, 17 fall into the sliver when they have returned to the extent required for the feeding: at the end of this reverse movement the elements 4, 5 are rapidly lowered so that the tuft is dabbed into the band 1, the elements are immediately opened, and a beater (not shown) forces the. projecting tuft ends below the element 5 and further into the band. The tufts 24 are also dabbed into a circular comb 3 at the uncombed end by guide means while the tops are drawn off by drawing-off devices 25, 26 in accordance with their different fibre lengths: noil 27 is lifted out of the comb 3 and band 1 by known devices.

[Also in Division H1] A resistor composition comprises 91-20% by wt. finely divided glass and 9-80% by wt. of a mixture formed by heating together ruthenium oxide and one or more of the oxides of the metals of Group V of the Periodic Table, any balance being compatible constituents. Preferably the composition consists of 46-65% by wt. of ruthenium oxide-Group V oxide(s) and 54-35% by wt. of glass. Preferably the Group V oxide is niobium pentoxide. The mixture may also include prior to heating 10% by wt. of an oxide or oxides of one or more of the metals of Groups I and II of the Periodic Table. In further examples not less than 50% by wt. of the ruthenium oxide-Group V oxide(s) mixture in excess of 9% by wt. is replaced by silver, an oxide of silver or a mixture of metallic silver and an oxide thereof. The composition is prepared by mixing together the constituents, ball-milling them to a particle size of from 0À01 to 50 Á and mixing them with a binder vehicle consisting of ethyl cellulose dissolved in an alcohol or ester, such as butyl glycol ester so as to form a suspension consisting of 75% by wt. of finely divided material in 25% by weight of binder. This suspension is then screen printed on to a substrate, e.g. mica sheets, to form a coating 0À0004 to 0À0006 inch and the whole passed through a lehr at 600-650‹ C. for 20 minutes to form a resistor having a mean resistivity of from 30 to 80,000 ohms per square per 0À001 inch thickness. Glasses used are lead borosilicate or a zinc borosilicate of the following composition in wt. per cent: Na 2 O 10À0; Al 2 O 3  3À0; ZnO 33À1; ZrO 2  4À0; B 2 O 3  25À2; SiO 2  24À5.

A glow-discharge gas-filled indicator tube, comprises a filling of an ionizable gas and mercury, wherein the mercury reduces the energy of the ions and so sharply reduces the amount of spluttering from the cathode. In one form the device comprises a stack of cathodes of stainless steel, molybdenum, aluminium or " Nichrome " (Registered Trade Mark), shaped in the form of numerals mounted on two insulating supports. During assembly a small glass vial containing mercury and a heating filament is introduced into the device which is then evacuated, filled with a rare gas such as Ne or other ionizable gas at a pressure between 50-100 mms. of Hg, preferably 70 mms. of Hg, and the device is sealed. The tube is then partially aged, the filament is heated, thus shattering the glass vial, and liberating mercury vapour into the lamp; the aging of the tube is then completed. Alternatively, after sealing, the mercury may be liberated immediately and the tube is then aged completely. Any other method of introducing the mercury may be employed, i.e. a side tube may be used. The stack of cathodes are contained in a cup-shaped anode, which rests on a mica disc, and which has two diametrically disposed slots in its wall to enable leads to reach the cathodes, the anode thus also acting as a shield.

Abstract: Naphtha fractions are separated into their aromatic and paraffinic constituents by solvent extraction with a specified selective solvent for aromatic hydrocarbons and a paraffinic co-solvent, both the solvent and the co-solvent having a boiling point at least 50 DEG  F. above the <PICT:0812114/III/1> end boiling point of the petroleum oil.  The aromatics are recovered from the solvent phase and the paraffins from the cosolvent phase by distillation and the solvent and co-solvent are recycled to the extraction zone.  The specified solvents are the alkane dinitriles, dimethyl hydantoin, N-alkyl pyrrolidones, gamma butyrolactone, the cyanoethers of diethylene glycol, and tri- and tetraethylene glycol.  The preferred co-solvents are straight- or singly-branched chain C10-16 hydrocarbon fractions boiling between 350 DEG  and 550 DEG  F.  The extraction zone may be operated at 50 DEG  to 300 DEG  F. with a solvent : feed ratio of 0.5-2:1 and a cosolvent : solvent ratio of 0.1-1:1.  Feed is introduced through line 2, passing through preheater 4 to the middle of extraction column 6.  Solvent esters at the top of the column from line 22 passes downwards dissolving the aromatic constituents of the feed, and is removed from the bottom of the column via line 24 and passed to distillation column 32.  In column 32 the aromatic extract is distilled off and removed via line 34 while the solvent is passed via lines 36 and 28 to separator 30.  The cosolvent enters at the bottom of column 6 via line 14, passes upwards dissolving the paraffinic fraction and is removed via line 8 and passed to distillation column 10.  In column 10 the paraffinic constituents of the feed are distilled off and removed via line 26 while the co-solvent passes via line 28 to separator 30.  The solvent and co-solvent separate into two phases in separator 30 and are recycled to lines 22 and 6 via lines 20 and 14 respectively.
