Title: Improvements in or relating to the production of composite yarns having shrinkage effects and the fabrics containing them
IPC: D06M11/38
Filed: 1949-05-04
Abstract: A composite yarn, formed from at least one singles yarn of a cellulose organic ester and at least one singles yarn of another material, is immersed in a 6-28 per cent by weight aqueous solution of ammonia or of an alkylene diamine containing 2 or 3 carbon atoms in the alkylene group for 6-15 hours at 25-30 DEG  C. so that the cellulose ester component is completely saponified and converted throughout its cross-section to regenerated cellulose, and the composite yarn is subsequently dried in the absence of tension.  The freshly regenerated cellulose yarn contracts but the other yarn is of such a material that it is unaffected by the treatment and does not contract appreciably on drying.  This yarn therefore becomes looped or wrapped around the freshly regenerated cellulose yarn and the composite yarn assumes a permanently crimped condition.  The inert yarn which is associated with the cellulose ester yarn may be of silk, cotton, flax, or regenerated cellulose from viscose or cuprammonium-cellulose solution.  The treated composite yarn may be woven to produce boucl<\>ae or ratine fabrics.  Such fabrics may consist wholly of the composite yarns, or the composite yarns may alternate with plain yarns in the warp or weft.  The composite yarns may be formed into knitted fabrics.  The treated composite yarn may be dried in relaxed state at 90-95 DEG  C.  In an example, a plied yarn is formed from a 150 denier/90 filament dull viscose yarn with a twist of 3 S turns per inch, and 150 denier/41 filament dull cellulose acetate yarn with a twist of 3 S turns per inch.  The plied yarn has a Z twist of 8 turns per inch.  The yarn is immersed in skein form in a bath consisting of 15 per cent aqueous ammonia solution for 15 hours at 25-30 DEG  C.  The yarn is washed and then dried in relaxed condition.  The freshly regenerated cellulose yarn becomes shrunk by about 40 per cent, causing the other yarn to wind itself about the shrunken component.  The composite yarn is used as the weft for a fabric, the warp yarns of which consist of an end of 150 denier/90 filament dull viscose yarn having 3 S turns per inch, alternating with an end of 150 denier/41 filament dull cellulose acetate yarn.

Title: Improvements in or relating to connection systems for automatic telephone plants
IPC: H04Q3/00
Filed: 1926-05-10
Abstract: 272,022. Marks, E. C. R., (Automatische Fernprech-Anlagen-Bau-Ges.). May 10, 1926. Automatic exchange systems.-In a system in which connections from a subscriber's preliminary selector VW to a first group selector IGW are made normally over direct trunks a<1>2, b<1>2, c<1>2 but when all these are busy are extended by way of an additional non-numerical switch AS of call-finder type, the same group selectors are available for both kinds of connection. For this purpose, all the first selectors TGW in a large group corresponding to a number of groups of subscribers' lines are linked with call-finders and whilst only a sub-group of the first selectors is accessible directly from a particular preliminary selector VW, the whole of the first selectors in the large group are accessible by way of the overflow links a4, b4, c4 and the finders AS. When a call is extenderl over an overflow link, an idle group-selector with its associated finder is assigned by a switch S. Normal connection over a, direct trunk. The subscriber's line relay R closes a circuit for the stepping-magnet D and connects battery to winding I of the test relay T. When an idle trunk a<1>2, b<1>2, c<1>2 is reached, relay T operates in series with relay C at the group selector IGW, and locks up over a local circuit including its winding II., off-normal contacts 11 and relay contacts 12, 10. The connection of relay M to the test wiper cl over contacts 9, d1 marks the selector IGW busy. During conversation the wire c<1>2 is open-circuited but at the end of conversation a direct earth connection is applied at the group selector over contact 15 causing relay M to operate and unlock relay T. Magnet D then returns the switch VW to normal. Overflow connection over finder AS. If all the direct trunks are busy, the switch VW selects an idle overflow link a4, b4, c4, and relay R1 operates in series with relay T, completing the circuit of relay An which causes switch S to hunt for an idle group selector. When this has has been found relays Po, II operate in series with relay C at the group selector, relay H causing the associated finder AS to hunt for the link a4 - - c4. Relays Pa, T1 then operate and lock in series over wiper d, thus completing the throughconnection to the group selector. At the end of conversation, relays M, Tr energize in series over contact 15 and unlock relays T, T1, Pa,

Filed: 1942-08-29
Abstract: 562,856. Making soaps; soap powder. PROCTER & GAMBLE CO. Aug. 29, 1942, No. 12210. Convention date, June 12, 1942. Addition to 555,034, [Group V]. [Class 91] Beta phase soap prepared by agitation of a mass of soap of appropriate composition within a temperature range as defined in the parent Specification is converted into soap flakes by forming the soap mass into ribbons and then reducing the moisture content while maintaining a temperature at which no substantial reversion of the beta phase to another phase takes place. The agitation operation may be combined with cooling and may be carried out within the narrower temperature range of which the upper limit is the highest temperature at which the soap will flow under gravity and the lower limit the temperature below which the soap loses its pasty consistency, e.g. from 160 F. to 115 F. The soap should contain at least 15 per cent of sodium soaps of saturated fatty acids containing from 16 to 22 carbon atoms per molecule, e.g. soaps of tallow fatty acids. Soap builders may be added and the soap may be aerated. As shown in the drawing, melted soap containing about 20 per cent moisture at 224 F. is passed from a crutcher 46 into a cooling and agitating device 31, 42 constructed as described in the parent Specification. Compressed air may be introduced from a valve 22 and a soap builder such as sodium silicate may be supplied by a pump 54 and pipe 48. The mixture passes through pipe 49 and nipples 62 to a feed hopper 63 mounted above a revolving chilling roll 60 and a hot feed roll 64. The soft pasty soap forms a film on the roller and after passing partly round the roller is scored by wires 65 to form ribbons usually from  to 1 inch wide which are removed by a doctor knife 66. and fall on to a belt conveyer 68 which conveys them to a flake drier 61. Here the ribbons pass through currents of dry heated air such that the temperature never exceeds 160 F. and the dried ribbons, finally containing about 10 per cent of moisture and at a temperature of 110 to 115 F., break into flakes and are discharged by a convever 69.

Title: Improvements in and relating to apparatus for the liquid treatment of textile threads
IPC: D06B1/02
Filed: 1948-05-07
Abstract: <PICT:0645171/IV (a)/1> Artificial threads are subjected to aqueous liquid treatment while passing over a roller, having its surface divided into at least one liquid treating zone and a boundary zone, the surface of which is not wetted by the liquid used so that the liquid supplied to the treating zone will not normally pass across the surface of the boundary zone.  The roller may have two or more treating zones separated by boundary zones, and it may have a drying zone separated from a treating zone.  A boundary zone may be situated at one or both ends of the roller to prevent liquid passing to the bearings supporting the roller.  The boundary zone may be formed by cutting an annular channel in the surface of the roller and filling it with a material which will not be wetted by the liquids used. Such material may be roughened to facilitate the projection of liquid droplets from its surface.  In the case of artificial threads made from viscose, the treatment liquids may comprise washing, desulphurizing, and bleaching liquids and these may be applied to separate zones of the roller.  For such treatments, the boundary zones of the roller may be made of solid ethylene polymers, solid tetrafluorethylene polymers, or solid interpolymers of tetrafluorethylene and other substances, e.g. ethylene.  The drying zone if present may be internally steam-heated or the roller may be internally steam-heated along its length.  The roller may be cylindrical or it may be tapered, frusto-conical, or stepped to allow for stretching or relaxation of the thread passing over the roller. Two rollers may be provided and these may be mutually inclined and arranged with their axes in the same or different planes.  As shown, artificial filaments issue from jet 4, and the thread 6 passes to the stepped end 8 of roller 9.  It passes several times to and from the ends 8 and 10 of rollers 9 and 11, and then passes round the main part of rollers 9, 11, being advanced in helical turns to the other end of the rollers.  The thread is treated with liquids from pipes 21-24, and used liquids are collected in troughs 25-28.  The roller 11 is provided with bands 18-20 of material which is not wetted by the treating liquids.  The thread passes to drying device 29 where it is passed several times round a steam-heated roller 30.  The thread then passes to a winding device 33.  In an example, a thread regenerated from viscose is drawn from the bath by a godet and stretched between the godet and a pair of inclined rollers along which it is advanced in helical turns and on which it is treated with liquids in zones separated by bands of polythene.  The final zone, which is a drying zone, is provided by a steam-heated metallic portion of one or both of the rollers. Specification 423,152 is referred to.
