Title: Improvements relating to the decorative treatment of fabrics
IPC: D06P5/12
Filed: 1930-02-21
Abstract: Cellulose acetate, dyeing; printing.-Decorative effects are produced upon fabrics made of or containing cellulose acetate by applying one or more dyestuffs having an affinity for cellulose acetate and capable of forming insoluble complexes with metallic salts or oxides, before or after the local application of a metallic salt and/or oxide capable of forming an insoluble complex with the dyestuff or dyestuffs, steaming or ageing, and applying a reagent, such as a dilute acid, to remove the insoluble complex p  where formed. Suitable dyestuffs are those of the oxazine series formed by condensation of nitrosodimethylaniline with gallic acid or its derivatives and applied, if desired, in the form of their leuco compounds, monoazo mordant dyes, e.g. Alizarine yellows, triphenylmethane mordant dyestuffs, and aminopolyhydroxyanthraquinone, having sufficient affinity for cellulose acetate, e.g. Alizarin Maroon.  Suitable discharge or resist preparations are a thickened solution of zinc acetate, a suspension of zinc oxide with or without zinc acetate, or preparations containing salts or oxides of the alkaline-earth metals, e.g. calcium, or of the heavy metals, e.g. lead. Dyestuffs having affinity for the cellulose acetate and incapable of forming insoluble complexes with the metallic salts or oxides, e.g. aminoazo compounds or aminoanthraquinones, and, according to the Provisional Specification, Duranol, S.R.A., and Cibacet colours in general may be incorporated with the discharge or resist preparation.  The following examples are specified.  (1) A cellulose acetate fabric is printed with a thickened solution of zinc acetate, padded with a solution of Prune pure, preferably in the form of its leuco compound, steamed, passed through a weak bath of acidulated sodium bichromate, washed and dried to obtain a white pattern on a blue ground.  (2) The Prune pure in (1) is replaced by Alizarine yellow R to obtain a white pattern on a yellow ground.  (3) Dispersol fast red A is incorporated in the printing preparation in (1) or (2) to obtain a red pattern on a blue or yellow ground.

Abstract: 782,761. Valve amplifying circuits. TELEFUNKEN GES. Feb. 28, 1965 [Feb. 27, 1954], No. 5808/55. Class 40 (6). In a cascode amplifier the anode of the first valve is coupled to the cathode of the second by a pair of coupled tuned circuits, viz. inductances L1, L2 which are coupled together by mutual inductance and a coupling 'condenser C3, and tuned to the same, or alternatively to different frequencies by capacities C1, C2 respectively. The coupling is made as tight as possible and the resonant frequencies of the circuits placed at the low frequency end of the waveband passed so as to minimize valve noise over the band of frequencies covered. The first valve may be neutralized. The inductances L1, L2 may comprise a single tapped coil, Fig. 2 (not shown), while an additional inductance in series with a blocking condenser may be shunted across the condenser C3, Fig. 3 (not shown). Thus, inductance may alternatively be connected in shunt with condenser C1 or C2.

Abstract: 691,996. Bending tubes. HUET, A. March 12, 1951 [March 10, 1950; July 7, 1950], No. 5899/51. Classes 83 (ii) and 83 (iv). In forming tube bends a tube is bent in successive operations over a length not exceeding that which will remain in the finished bend, each operation reducing the radius of curvature of the partly formed bend. A tube a, Fig. 2, which is to be bent through an angle of 180 degrees is first bent through 90 degrees by backing-up rolls c, c<SP>1</SP> over a rotatable former b to which it is held by a yoke d. The bent tube is then further bent to 180 degrees over a former b<SP>1</SP>, Fig. 4, by backing-up rolls c, c<SP>1</SP>, the roll c<SP>1</SP> being adjustable in position so as to engage the initially bent tube. The process may be carried out in any number of stages over formers with successively reduced diameters. Heat may be locally applied to the inner part of the bend as described in Specification 649,638, and the tube may be initially deformed to elliptical &c. cross-section in the region of bend to reduce the resistance to bending. The method may be applied to tubes of unsymmetrical cross-section in which a part of the wall is thickened and arranged in the outer part of the tube bend, the inner part being thickened during the bending process. Specification 663,427 also is referred to.

Filed: 1952-03-13
Abstract: <PICT:0744749/IV(c)/1> <PICT:0744749/IV(c)/2> <PICT:0744749/IV(c)/3> A machine for moistening textile materials is provided with screens which are resistant to the effects of water and which have a water flow maintained down them by feeding at opposite ends so that a wave travels along the length of each trough.  Figs. 1 and 3 show a textile moistening machine in which the material 4 passes in zigzag fashion over a series of upper and lower transverse rollers 2, 3 which may be driven or freely rotatable. Between each vertical stretch of the material 4 is arranged a screen 5 of thin aluminium sheeting down both sides of which water is passed from tubes 6 which have longitudinal slots 7, Fig. 5, on their upper surfaces.  The tubes are fed with water either from a channel 9 and supply pipe 10 under the action of pump 12 through a valve or alternatively via connections 14, 15 and 17. The water flow down each screen 5 is collected in a trough 20, the troughs being tilted so that the water passes via a shoot, Fig. 2 (not shown), into a storage tank from which the pump 12, Fig. 3, draws its supply so that a closed water circulation system is employed.  By operation of the appropriate valves the water supply to the screens 5 is derived first from one and then from the other side of the machine so that a wave effect which ensures an even distribution of the water over the screen is produced. The screens 5 are treated with a caustic solution which causes oxidation of their surface and thereby creates a surface to which water will more readily adhere.

Title: Method and apparatus for the manufacture and closing of the inner lining bags in packages comprising an outer case with an internal lining
IPC: B31B50/00
Filed: 1953-03-10
Abstract: 725,340. Making bags; closing receptacles after filling. HESSER MASCHINENFABRIK-AKT.,-GES., F. March 10, 1953 [March 10, 1952], No. 6591/53. Classes 94 (1) and 94 (2). A method of manufacturing bags, particularly inner linings, on a rotary mandrel co-operating with a former, and using heat sealing, is characterised in that a web of foil is fed to the former in conjunction with compressed air which flows between the web and the web supporting surfaces of the former, or with the assistance of additional mechanical means, the folded flaps of the foil blank are held to the mandrel by suction before and during the heat sealing operation, and the finished bag is removed from the mandrel with the assistance of compressed air. As shown, a plurality of mandrels 2 are carried by a wheel 1 which is intermittently rotated in a horizontal plane. At station I the web of thermoplastic material or metal foil F is drawn from a supply reel and fed forward on a runway 25 by rollers 10, '11, and is cut into predetermined lengths by knives 12, 13. To prevent the end of the foil, which is fed on to the supporting surfaces 3a of the former 3, from rolling up or sticking on the supports, a fan-shaped stream of air is blown between the surfaces 3a and the foil, the air stream being controlled automatically as by the movement of the knife 13. In a modified arrangement for feeding the foil, Fig. 6 (not shown), a pair of endless conveyer belts feed the foil to the former 3 and when the former is raised to fold the blank into U-form around the mandrel, the drive to the belts is automatically interrupted. Alternatively rotating or reciprocating grippers may be used. After the blank has been folded into U-form in known manner, the side flaps which project above the mandrel are turned over by the folding blades 4, the blank being held in position by suction acting through openings 21 provided on the upper surface and the side surfaces of the mandrel 2, the suction being controlled by the rotation of the mandrel wheel 1. At station II the two lateral bottom flaps and the rear bottom flap are folded over in known manner by members 5 and 6, the flaps being held to the end surface of the mandrel by suction through the holes 22 and a heat sealing tool 7 is pressed against the longitudinal seam of the bag. During the movement to station III a bar 8 folds over the remaining flap, and at station III the bottom flaps are sealed by a heat sealing tool 9. At this and the following stations the folding over and sealing of the outer case of the bag is completed in known manner. The finished bag consisting of an outer case and an inner lining is ejected at station VII this operation being assisted by compressed air passing through the openings 24 in the end face of the mandrel. The bag is then filled and the mouth B of the inner container, Fig. 7, is heat sealed to form a very narrow seam N which facilitates the subsequent folding of the mouth portion.
