Title: Improvements in and relating to tris-acetamido amines
IPC: C08G63/685
Filed: 1965-06-24
Abstract: Novel and other tris N-substituted acetamido amines of the formula N(CH2-CONH-CH2R)3 wherein each R is hydrogen or a C1- 10 hydrocarbon radical, are prepared by reacting nitrilotriacetonitrile with water and a primary hydrocarbon amine of the formula H2N-CH2R at a temperature in the range 40 DEG  to 150 DEG  C. to form a reaction product which is dried to a water content of less than 3% by weight and then contacted with a water soluble organic fluid which is soluble in water to the extent of at least 30 grams per 100 c.c. of water.  Exemplified products are tris-(N-benzylacetamido)-amine, tris (N - cyclohexylmethylacetamido)-amine, tris(N-decylacetamido)amine and tris (N-methylacetamido)amine.  The products may be further reacted with ethylene oxide or with chlorine to give tris N-polyethoxylated and tris N-chloroamide derivatives.ALSO:Cotton and rayon fabrics are crease proofed by impregnation with 0.5 to 3% by weight of N-methylol derivatives of tris N-substituted acetamido amines having the formula N(CH2 -CONH-CH2R)3 (wherein R is hydrogen or a C1-10 hydrocarbon radical) and a small amount of a suitable catalyst such as zinc nitrate, ammonium chloride, diammonium phosphate, triethylamine hydrochloride or triethanolamine phosphate, followed by heating to effect the desired cross linking reaction.

Title: Improvements in gas-cutting machine
IPC: B23K7/00
Filed: 1919-11-04
Abstract: 158,365. Percival, S., (Davis-Bournonville Co.). Nov. 4, 1919. Dividing by fusion.-In a gas cutting-machine of the type in which the torch and a mechanically-driven feed-wheel are carried by an overhanging frame pivoted on a standard so that they are universally movable in an horizontal plane, the torch, driving-means, and feed-wheel are mounted in a carriage freely movable on a radial guide arm pivoted on the standard, so that the carriage mav move on the arm as it is swung round the standard according to the shape of cut or of the article to be cut. In the form shown in Fig. 1 for trimming and bevelling a flange 29 to the caulking angle, a radial arm 6, supported by a stay-rod 10 and carried by a hub 4 rotatably mounted on a post 2 which is vertically adjustable, forms a guide for a roller carriage 13 having handles 14 and carrying also an electric or other motor 15. The motor rotates the shaft 25 of the feed-wheel 28 through worm gear 16, 17, 20, 21 and bevel-gear 26. On the shaft 25 is swivelled a sleeve 30, to which is pivoted at 33 an arm 32 carrying slides 37, 47 adjustable respectively horizontally and vertically by screws operated by hand-wheels 46, 49, the wheel 49 being connected to its screw by bevel-gear. The torch 42 is carried by a bracket 39 secured to the slide 47 by a screw 43, and is arranged to impinge on the work in the vertical plane intersecting the point of contact of the feed-wheel with the flange, being also provided with an inclined tip so that the flange is out on a bevel. The arm 32 has a rod 34 with two pressure rollers 35 which are pressed against the flange by the weight of the arm so as to hold the feed-wheel in driving contact therewith. The feed-wheel has a heat-protecting cylindrical guard 44 with a flared base 45. In making curved, irregular, or straight line cuts in a downward direction in plates and sheets by this machine, the bracket 39 is turned up and clamped with the torch in a vertical position, or a second torch may be substituted. The feed-wheel and pressure rolls are arranged to travel on an angle-iron or other templet flange. In the form shown in Fig. 5, for cutting holes in underlying plates such as boiler heads, the depending structure of the carriage which may be made as an attachment to replace that shown in Fig. 1, consists of a frame 52 attached by a screw 53 and elongated slot 63 to the frame 24, and containing a rotatable hollow swivel 54, with a bifurcated end to receive the feedwheel 57. This swivel is rotated by a handwheel 55 in accordance, with the shape of cut, through bevel-gear 56. The frame 52 is pressed down by a spring 65 to avoid binding against the arm 6. The driving-shaft 25a is connected by an elongated key 64 to a worm 59 which is carried by the swivel and rotates the feed-wheel through a worm-wheel and spur gear 58. The torch 61 is carried by a bracket 60 secured to the frame 52.
Patent GB-390176-A (GB)
Title: Improvements in or relating to textile materials
IPC: D06M11/13
Filed: 1931-09-29
Abstract: Textile operations normally performed upon dry filaments, threads, &c. of organic derivatives of cellulose are facilitated by treating the materials with, or incorporating therein, a hygroscopic or deliquescent solid substance and retaining the latter on or in the materials during the textile operations. Suitable solid substances are sodium, potassium, or ammonium acetate, formate, or phosphate, ammonium citrate, the chlorides of magnesium, calcium, zinc, iron, and strontium, the nitrates of magnesium, calcium, zinc, iron, cobalt and nickel, amides such as acetamide, or amine salts such as methylamine hydrochloride and quaternary ammonium salts.  The solids may be applied in solution or dispersion in water or an organic liquid, e.g. ether, benzene, or di-isopropyl ether.  The cellulose ester or ether filaments may be in the form of short lengths, e.g. staple fibres, or of continuous lengths, and may, if desired, be mixed with other materials, for example, of cotton, silk, wool or regenerated cellulose.  The application of the hygroscopic solid may be carried out continuously with the production of the filaments or during subsequent winding or twisting and winding operations.  The application of solutions or dispersions of the solids to running yarns is effected, for example, by means of wicks, pads, drip tubes, rollers, or discs.  Again the liquid may be applied to hanks, bobbins, or packages by immersion, or to yarn wound on perforated tubes or bobbins by forcing the liquid through the yarn.  In a further method, the hygroscopic solids are incorporated in the spinning solutions from which the filaments are produced.  In an example, short filaments of cellulose acetate are immersed in hot soap solution, rinsed firstly in water, then in a 1 per cent magnesium chloride solution and finally dried. Specification 366,585 is referred to.  The Specification as open to inspection under Sect. 91 refers to the treatment of textile materials in general, including yarns composed of cotton, silk, wool, or regenerated cellulose, and also to the treatment of films of cellulose esters or ethers.  The use of solutions or dispersions of the hygroscopic solids in alcohol, aqueous alcohol or hygroscopic liquids such as ethylene glycol, diethylene glycol, or glycerine, and the application in conjunction with the hygroscopic solids, of softeners such as triacetin, ethers of ethylene--or other olefine--or polyolefine-glycols, are also mentioned.  This subject-matter does not appear in the Specification as accepted.

Title: Direct-voltage system comprising static converters interconnected through interphase transformers
IPC: H02M7/15
Filed: 1958-08-26
Abstract: 848,161. Rectifying. ALLMANNA SVENSKA ELEKTRISKA A.B. Aug. 26, 1958 [Aug. 31, 1957], No. 27300/58. Class 38 (2). In order to prevent commutation from starting, at very low loads, between anodes belonging to two different groups 2 and 3 of floating grid rectifiers, such as 1, with consequent voltage rise due to shifting into six-phase operation, the discharge paths of a group the current of which temporarily becomes zero, are blocked when the direct voltage exceeds the no-load value. The two commutating groups are fed by star-connected secondaries 4, 5 having their neutral points connected by an interphase transformer and the blocking is done by a self-excited transductor amplifier 17 which applies the blocking voltage to grid voltage device 15. The transductor 17 has a control winding 22 connected across the D.C. lines 10, 11 and an opposing winding 23 fed from the alternating voltage mains 8. When the load current falls sufficiently to reach the under-critical range, rise of the direct voltage causes winding 22 to predominate so that one commutating group is blocked. To prevent repeated blocking and unblocking a third winding 27 which assists winding 23 is fed from a bridge-circuit comprising two halves of resistor 30 and the windings of a measuring transductor 29, the output being dependent on the current from the rectifier 1 but only in a very narrow range close to zero. Metal rectifier 32 through which winding 27 is fed has an output voltage which remains substantially constant until the direct current through transductor 29 falls close to zero, when it decreases quickly. A number of rectifiers in parallel may be successively blocked or unblocked in dependence on the load. To avoid all the three-phase groups being blocked a basic load resistor 34 may be provided or the direct voltage windings in the transductors may serve this purpose. The transductor 17 may be unstably self-excited and have two voltage-sensitive windings so that a blocking voltage may be produced at a direct voltage somewhat above the critical voltage while the rectifiers are unblocked at a somewhat lower voltage.

Abstract: 1,126,800. Apparatus for forcing fluids through hides, skins &c. CENTRE TECHNIQUE DU CUIR. June 21, 1966 [July 1, 1965], No.27563/66. Heading C6C. [Also in Division D1] . Apparatus, Fig. 1 forcing a treating fluid, e.g. a liquid, into and through a permeable sheet, such as an animal skin or hide, or a sheet of leather 16, comprises a lower cell 2 connected, by a pipe 3 to a source of suction. The mouth of the cell 2 is reinforced by a frame 4 carrying a substantially rigid, perforated plate 5, which extends over the mouth and supports a porous wool or felt mat 6, on which the sheet 16 is placed. The apparatus also comprises an upper deformable cell 7 having a frame 8, identical with frame 4, and a rigid, circular or polygonal plate 9, which is rigidly connected to the frame 8. The plate 9 and frame 8 are also connected by a fluid-tight, elastic, preferably frusto-conical diaphragm 11, whose edge forms a fluid-tight seal between the cells 2 and 7. Treating fluid is fed, from a container 14, into the cell 7 through a valve 13 and a pipe 12. The latter has a branch 15 leading into the outer atmosphere. The apparatus is operated as follows. The valve 13 is closed, the cells 2 and 7 are separated, and the sheet 16 is placed on the mat 6. The frames 4 and 8 are then secured to each other to hold cells 2 and 7 tightly together. The cell 2 is connected, by the pipe 3, to the source of vacuum, and, since there is a fall in pressure from cell 7 to cell 2 (because the volume of air sucked from cell 2 is greater than the volume of air entering cell 7 through pipes 15 and 12) the diaphragm 11 is urged against the peripheral part of the mat 6 not covered by the sheet 16, as shown by the interrupted lines 11. The valve 13 is then opened to admit treating fluid into cell 7 and this fluid is sucked through the sheet 16. In a modification, Fig. 2 (not shown), the upper cell 7 is covered by a rigid bell (17); the branch 15 is connected to the atmosphere through a valve (21), and to a source of compressed gas through a pressure-reducing device (19) and a pipe (18), which is connected to the bell. In another modification, Fig. 3 (not shown), the plate 9 is not rigidly connected to the frame 8, and the distance between plate 9 and frame 8, can be varied by turning a bush nut (22), which is turnably mounted in the top of the bell (17) and engages screw threads on the pipe 12, turning of which is prevented.
