Title: Method of forming all skin artificial threads and like articles from viscose
IPC: D01F2/10
Filed: 1955-09-15
Abstract: Filaments, films and like products of regenerated cellulose consisting entirely of skin are produced by extruding viscose containing about 0.25-4 per cent, preferably 0.5-3 per cent, based on the weight of the cellulose, of an alkylene oxide adduct of ethylene diamine into an aqueous spinning bath containing about 10-25 per cent, preferably 15-22 per cent, of sodium sulphate, about 3-15 per cent of zinc sulphate and/or other heavy metal sulphate and sulphuric acid, the concentration of the latter exceeding the slubbing point but being below the concentration at which the products consist of skin and core.  The alkylene oxide adduct contains at least about 28 up to 100, preferably 32-60, alkylene oxide units per molecule of ethylene diamine and is soluble in water and in dilute aqueous solutions of caustic alkalies and of acids.  The coagulating bath may contain at least 0.02 per cent, preferably 0.05-0.15 per cent, of the ethylene oxide adduct.  The temperature of the bath may be about 25-80 DEG  C., preferably about 45-70 DEG  C.  When only the viscose contains the adduct, the percentage of acid in the bath should not exceed about 1.4 times the percentage of caustic soda in the viscose and is preferably about 1.2-1.35 times the latter.  If the bath contains at least about 0.02 per cent, preferably about 0.05-0.15 per cent, of the adduct (the adduct being also present in the viscose in the proportions specified), the percentage of acid in the bath may be up to 1.6 times that of the caustic soda in the viscose.  The products may be stretched after leaving the initial coagulating bath and then passed through a final regeneration bath containing about 1-5 per cent of sulphuric acid and about 1-5 per cent of sodium sulphate, with or without small proportions of zinc sulphate.  In an example, 1 per cent (based on cellulose) of an adduct containing about 50 ethylene oxide units per molecule of ethylene diamine is added to viscose containing about 7 per cent of cellulose and 6 per cent of caustic soda and having a 41/100 carbon bisulphide/cellulose ratio.  The viscose is allowed to ripen to 10.8 salt point and is spun into a bath containing 7.2 per cent of sulphuric acid, 20 of sodium sulphate and 8.4 of zinc sulphate, the temperature of the bath being 60 DEG  C.  The filaments are then stretched 82 per cent in water at 95 DEG  C. and collected.

Title: Improvements in apparatus for and methods of fixing preformed outsoles to the bottoms of lasted footwear uppers with adhesive
IPC: A43D25/08
Filed: 1967-06-09
Abstract: 1,134,359. Boots &c. COMPO INDUSTRIES Inc. 9 June, 1967 [13 June, 1966], No. 26633/67. Heading A3B. A machine for fixing preformed outsoles to the bottoms of lasted uppers has a loading station 10, a gauging and spotting station 12 where an uncoated outsole is accurately positioned on the shoe bottom, is then picked up and coated with adhesive and is then returned to the same position, and a pressing station 14. The last supports are mounted on carrier plates 52 fixed to conveyer chains 22. The chains are intermittently advanced by a piston and cylinder M which reciprocates a chain 42 which is connected to the conveyer chains 22 by a one way clutch 50. The carrier plate 52 is accurately positioned at the gauging station 12 by a latch 99 which engages a notch in the plate 52. The last is supported by a spindle 66 (Fig. 2) pivoted to a heel post 62 and a toe rest 76 which can move along inclined guideways 88 to accommodate shoes of different sizes. A wedge 65<SP>X</SP> connected to the toe rest 76 automatically moves the heel post 62 to the correct height. The toe rest 76 is moved along the guides 88 at the loading station 10 by a ram 106 (Fig. 3) which may be controlled by a cam 110 or by a feeler arm (not shown) which operates the ram 106 until the last bottom reaches a predetermined level. The pre-formed outsole is positioned on the last bottom at the gauging station 12 by a heel gauge 116 (Figs. 2, 3) and a toe gauge 120. The gauges consist of resilient bands which are moved towards and embrace the toe and heel of the last and engage the ends of the outsole to position the outsole. The gauges 116, 120 are carried by arms 174, 194 which are swung towards the last by piston and cylinders 182, 202. When the outsole has been positioned the outsole is picked up by suction cups 258, 260 (Fig. 7) on a carriage 214 which runs along tracks 206. The carriage 214 is driven by a chain 204 from a position above the last to the position shown in Fig. 3 and back again. As the carriage 214 returns an adhesive applicator 306 is raised by piston and cylinder 320 so that the outsole is coated with adhesive. The carriage 214 is arrested at its initial position by stops 249 (Fig. 7) so that when the suction cups 258, 260 are lowered, the outsole is replaced in its gauged position and is spotted to the shoe bottom. The pressing station 14 (Fig. 5) has a fixed platen 332 which supports the carrier plate 52, and a movable platen 333<SP>X</SP> which runs on guides 336. The movable platen 333<SP>N</SP> is moved into operation position by two toggle mechanisms 342, 344 which are operated by piston and cylinder 340. Pressure is applied to the outsole by an inflatable bag 372 mounted on the platen 333<SP>X</SP>.

Filed: 1966-06-15
Abstract: 1,091,510. Measuring by thermocouples. LEEDS & NORTHRUP CO. June 15, 1966 [July 30, 1965], No. 26751/66. Heading H1K. [Also in Division G1] In measuring the temperature in a heated chamber by means of expendable thermocouples, the couples are fed one by one into a tube communicating with an opening in the chamber wall, connected into a temperature measuring system, pushed into the opening to effect a measurement, then disconnected from the measuring system and removed from the opening. In the Fig. 1 arrangement, expendable thermocouple elements 16 of plug-in type are fed from a magazine 15 into tube 12 in which piston 25 can be reciprocated by a reversible electric motor 41. The piston is withdrawn to allow an element to enter the tube from the magazine, the movement operating switch 45 to energize coil 51 thereby enabling mechanical stop 52 to enter the tube. As the piston is moved forward again the element abuts the stop and its plug end is forced into engagement with a socket 27 carried by the piston through which connection is made to the measuring circuit. When engagement is complete, the switch opens to withdraw the stop and allow the element to be fed to the opening. As the piston is withdrawn after the measurement a further switch 54 is operated to actuate stop 58 which engages a groove between plug and socket, causing them to disengage. The released thermocouple falls away through a hole in the tube wall and the process is repeated. In another arrangement (Fig. 3, not shown) for measuring the temperature of molten metal, in which the piston is moved hydraulically, engagement and disengagement of plug and socket are effected by spring and gravity loaded stops respectively. In this case the thermocouples and refractory plug elements with cardboard noses are fed alternately from the same or separate magazines. The refractory parts of the plugs seal the opening between measurements and continue to do so on withdrawal of the piston and are only forced out into the melt by feeding forward the next thermocouple. In a modification of this, the plug elements form the rear ends of thermocouple elements and carry the electrical contacts thereof. In both cases the plugs are prevented from fusing to the walls of the tube where it opens into the molten metal chamber by gas which is either generated from the plug material or fed past the plug, which may be slotted or a loose fit in the tube to allow this.
