Title: Process for production of tubes
IPC: B21K21/16
Filed: 1966-09-30
Abstract: 1,138,485. Making tubes; swaging; rolling; improving physical properties. PHELPS DODGE COPPER PRODUCTS CORP. 30 Sept., 1966 [20 Oct., 1965], No. 43926/66. Headings B3A, B3H, B3M and B3V. A cast copper tube is subjected to cold working, annealing and cold drawing to reduce the tube to finished size. The cold working may be performed by a rotary swager with radially moving dies 7, 8 and rollers to move the dies inwards. The swager reduces the tube cross-sectional area by 15-70%, preferably 20-10%. An hydraulic pusher moves the forward end of the tube through the swager until the end can be gripped by an hydraulic draw-bench (3), Fig. 1 (not shown). Alternatively the cold working is performed by a tube reducer 10 with grooved work rolls 15 which are reciprocated along the tube. Wedges 11 are inserted during the working stroke to the left and withdrawn on the return stroke. The tube is held stationary during the working stroke. After the cold working the tube is annealed between 1400‹ and 1700‹ F. for 30 minutes to 2 hours. Finally the tube is cold drawn in a conventional steel die and mandrel drawing apparatus.

Title: Improvements relating to nuts and other internally threaded fastening devices
IPC: F16B31/06
Filed: 1959-12-29
Abstract: 917,485. Tapping. ELASTIC STOP NUT CORPORATION OF AMERICA. Dec. 29, 1959 [Sept. 11, 1959], No. 44115/59. Class 83 (3). [Also in Group XXV] A nut or like internally threaded member 2 has its fatigue strength increased by providing a screw-thread 4 having a section 18 of standard form, a section 6 whose flank angles are less than that of section 8, and whose internal diameter is tapered, and an intermediate section 14 having flank angles which vary from the standard form to the form of the section 6. The root diameter, the pitch, and the flank angles of the thread inwardly of the pitch diameter P are constant in the three sections, and the lengths of the smaller angle flanks of the threads in the section 14 progressively increase from a point 16 up to the section 6, along a line 36. In a modification, Fig. 2, the smaller flank angles are joined to the larger flank angles in section 14, by angled faces 52. The clamping face 12 of the nut is relieved at 50, which, it is stated, increases the fatigue strength further. The complete thread may be formed by a composite tap having the three forms thereon, or the standard threads may be tapped first and then followed up by a tapered tap having the smaller flank angles.

Abstract: 989,600. Winding yarn; stop motions. MEIJI MACHINE CO. Ltd. Nov. 8, 1963 [Sept. 2, 1963], No. 44212/63. Headings DID and D1J. [Also in Division B8] Conical ended yarn packages which have no bobbin or core extending therethrough are built up on a conically shaped base in a machine which includes a platform adapted to slide upwards as the package grows and on which are mounted a pair of rotary conical presser members, a traverse mechanism and a pin which locates the tip of the conical package during winding. A vertically slidable platform 26 carries two cone members 23 which press against either side of the conical end of the package 70 and are frictionally driven thereby. The platform is suspended by a cord 33 attached at its other end to an adjustably counterweighted lever so that the contact pressure of the members 23 may be adjusted, the platform 26 being pressed upwardly as the package grows. A downwardly projecting rotatable pin 16 also carried by the platform 26 locates the tip of the package during the winding process. A quick traverse lever 41 similarly mounted on the platform 26 is operated by a rotating crank of adjustable throw and a ball joint connection (Figs. 4 and 5 not shown). The lever 41 oscillates in a vertical plane in such manner that a thread guide 44 traverses the conical end portion of the package 70. A knurled portion 60 on the traverse mechanism drive shaft allows for manual adjustment of the starting position of the lever 41. A yarn guide arm 61 is provided to cause a few turns to be wound initially on the end portion of the cop base, a timer also being provided to deflect arm 61 out of its operative position after a short period. A double-disc tensioner 65 is provided for the running yarn and also a stop-motion comprising a plate 68 normally held up by the running yarn but adapted on yarn breakage to stop the driving motor (not shown). The latter drives the package 70 at selectable speeds through pulleys 13, a switch 69 being provided to stop the drive motor when the package reaches a predetermined length. A manually-operated stop-button 71 is also provided for the motor. The drive spindle on which the cop base is mounted is provided with outwardly bowed springs (Fig. 3 not shown) to secure the cop base thereto. A foot operated lever (Fig. 2 not shown) is provided to raise the platform 26 for doffing the wound package 70.

The retaining means may alternatively be resilient hooks or biased upstanding members attached to the container. Preferably the aerosol containers rotate as they pass through the bath, but are only partly submerged. A window 14 is provided so that bubbles escaping through leaks may be seen. The aerosol containers are heated in a chamber, by means of a hot spray, before being immersed in the bath 9 to increase the internal pressure and are dried after immersion.

The ends of the loops 15 are deformed by means on the loom to form hook shapes so that the tape may be used in a sliding clasp fastener. The tape is woven by having an auxiliary sheet of warps 9 spaced above one of the main sheets 2, and always maintaining the same relative position thereto, double picks 4 of weft being inserted by a needle 24 between the main sheets 1 and 2, and double picks of selvedge thread being inserted from the opposite side between the auxiliary sheet 9 and the main sheet 2 by a second needle 28. One loop of selvedge thread is inserted for every two or more loops of weft, and the top ply of the selvedge is attached to the main ply by alternate weft picks 107, Fig. 25 and warp threads 111 corresponding to the upper main sheet of warp 2. The projecting loops 15 are formed by the entwinement of the selvedge thread 11 around a needle 31 which is supported only by the loops 15 themselves. Various embodiments of the needle are described, Figs 5-11 and 14 and 15, not shown all having a nose portion, such as 34, Fig. 4 projecting laterally from the shank around which the selvedge thread is entwined. The needle 31 is maintained in the same position relative to the loom as the fabric is advanced, either by an abutment 33 on the loom which is reciprocated or spring loaded to act on nose 34 of the needle so that the selvedge thread looped around the needle can pass, or by shaping the needle so that it is squeezed along the fabric by the loops 15 to compensate for the movement of the tape. The selvedge thread 11 may be of deformable material, for example nylon, or a thread coated wholly by deformable material or only in those parts which form the projecting loop heads. Alternatively, it may be a hollow tube of deformable material, which may be filled with a soft material or have a flattened rectangular cross section, or consist of a monofilament of a metal or metal alloy. In a further alternative, the thread 11 is a multifilament yarn. It may be marked in the locations which form the projecting loop heads.
