[Classes 66 and 125 (iii)] The heads, comprising the neck and shoulder portions, of collapsable tubes made from paper, millboard, &c. are formed in one piece with the body or skirt, the neck being reinforced by a pressed-on, moulded, or otherwise attached annular member of metal, synthetic resin, cardboard, &c. which holds the head of the tube in shape. The reinforcement may comprise a ring 3, Fig. 2, which shows the externally threaded neck 7 as having an integral or attached lining member 6, which may be of any desired sectional form, and the shoulder 2 formed with inwardly projecting ribs 21. Fig. 4 shows a reinforcement consisting of a wire helix 8 covered with paper &c. 9 and serving for the attachment of a screwed cap. In the form shown in Fig. 10 the threaded reinforcing member 11 is provided with a part 18 fitting inside the neck 7, both parts having extensions 19, 20, disposed respectively over and under and anchored to the shoulder 2. Fig. 12 shows a construction to take an internally fitting screwed plug. In Fig. 13 the outer and inner parts 25, 26 are formed separately and beaded together at 27. The body portions of the tubes may be coated with varnish, fabric, metal foil &c. to render them gas or liquid-tight, and metal foil &c. may be inserted between the plies of which the bodies are formed.

Title: Preparation of ª-alkyl-ª, ªÏ-diaminoalkanes
IPC: C07C209/48
Filed: 1966-06-01
Abstract: Beta - alkyl - alpha - omega - diamino - alkanes are prepared by (a) contacting a dinitrile of the general formula <FORM:1098962/C2/1> wherein n is 1-12 and R1 and R2 are each H or a straight or branched chain C1-C12 alkyl radical, with hydrogen at 10-100 DEG  C. and a pressure of less than 135 atmospheres in the presence of a hydrogenation catalyst and (b) contacting the resulting mixture with hydrogen in the presence of ammonia and/or a tertiary alkylamine at 50-150 DEG  C. at a pressure of at least 70 atmospheres in the presence of a hydrogenation catalyst.  Step (b) may be conducted in the presence of an inert diluent which exhibits a measurable solubility towards the dinitrile starting material and the ammonia or amine.  The amount of hydrogen employed in step (b) may be more than that stoichiometrically required to reduce both amine groups.  Some 3-methylpiperidine is obtained in the example.

Abstract: 733,290. Locking nuts. ELASTIC STOP NUT CORPORATION OF AMERICA. Sept. 8, 1953. No. 24788/53. Addition to 696,765. Class 89(1). [Also in Group V] A modification of the screw-threaded fastening device of the parent Specification comprises a body 10, Fig. 1, having an external thread 12 and one or more insert-receiving cavities 22 each consisting of two sockets 18 opening through the threads and interconnected by a bore 16. The locking insert is of mouldable, thread-impressionable elastic material, and comprises head-portions 24 retained in the sockets 18 by an interconnecting ligament 26 in bore 16 and projecting outwardly beyond the minor diameter of the thread to present locking surfaces for engagement by a companion internal thread. The elastic material may be of thermoplastic or thermosetting material, e.g., cellulose derivatives, vinyl and styrene derivatives, phenols, cresylics, anilines, ureas, melanimes, alkyds and fluorocarbons, and is preferably of nylon. Most of each socket and hence each head portion is situated between the major and minor diameters of the thread, whereby the strength of the body 10 is not unduly reduced. The insert material is injected into the cavity 22 through a bore 42, Fig. 4, dies 27, 28 being clamped to the body and having plugs 34, 36 which determine the shape of the locking surfaces. A number of dies are used in an injection moulding machine for simultaneous injection by a single stroke. In a modification, the sockets 18A, Fig. 8, are peripherally spaced at 90 degrees and interconnected by two bores 16A, 16B at right angles, and one socket and head portion may be omitted.

It slides down the surface to a first punching station against pins 318 and a cam-actuated bar 338 with resilient end 342 pushes the blank against an end stop pin 316. The first punching operation then takes place and bars 368 raise the blank clear of the pins to allow it to 'slide by gravity to be positioned for the second punching operation by a pin 302, pins 320 and a cam-actuated bar 340. After this operation cam-actuated bars 390 lift the blank clear of the pins and it slides to a delivery conveyer. Operation. The flat blank 391 is positioned by hand at the embossing station E. Fig. 13, and, on depression of a pedal the one revolution clutch operates and the formations F, Fig. 28, are stamped to form housings for the spring clips by the dies 204, 196. The blank then slides to the first punching station P<1> and on depression of the pedal slots S<1> extending front a line BB to beyond the centre line AA are punched by the punches 274 and the straps S are formed by the punches 253. The blank then slides to the second punching station P<2>, the pedal is depressed and slots S<2> extending from the line CC to beyond the line AA are punched to form continuous slots S together with the straps S<3>. A camactuated reciprocating cutter 282 shears the edges of the blank. The waste portion between the pin 302 and the shear is expelled by compressed air from a pipe 394 controlled by a cam-actuated valve.

Abstract: 1416502 Bleaching textiles PULP & PAPER RESEARCH INSTITUTE OF CANADA 25 May 1973 [30 May 1972 9 May 1973] 25117/ 73 Heading D1P A process for bleaching, of a textile in cloth or yarn form, comprises contacting the fabric adjusted to a suitable moisture content, with chlorine monoxide in admixture with an inert gas or liquid carrier. Where the carrier is a gas e.g. air, nitrogen or oxygen, the chlorine monoxide may be diluted with the gas to a partial pressure of from 1 to 253 Torr, to provide from 0.1 to 1.0% of chlorine monoxide on the weight of the dry fabric, the contacting time being from less than one second up to 300 seconds. Where the inert carrier is a liquid, it is a non polar solvent for chlorine monoxide, for example carbon tetrachloride, triahloroethylene, tetrachloroethylene or a fluorinated hydrocarbon, the contacting time being- from 1 to 30 minutes. The moisture content of the fabric may lie in the range of 80-20%. The process may be carried out to a narrow terminal pH range selected to fall within the broad range 1 to 13, preferably 'by treating the fabric with an alkali e.g. sodium hydroxide or sodium carbonate, prior to the chlorine monoxide bleaching step. The chlorine monoxide bleaching step may be preceded by a de-size washing step and a caustic soda scour, and followed by a washing step and a drying step. Fabrics of natural fibres e.g. cotton, linen, jute, and hemp, alone or in combination with a man-made fibre e.g. a polyamide, polyester, rayon, cellulose acetate or triacetate, acrylic fibre or a polyolefin, may be treated.
