Title: A container and plug assembly
IPC: B65D39/08
Filed: 1963-11-04
Abstract: 1,032,701. Container closures. V. B. CETRONE. Nov. 4, 1963, No. 43400/63. Heading B8T. A threaded plug 11 of resilient resinous material seals an opening of a container 10 having an internally threaded sleeve 16 tapered at 19 extending through the opening by engaging the tapered portion 19 by means of a knife-like edge 26 of diameter greater than the smallest diameter of the sleeve bore but smaller than the largest diameter of the sleeve bore, the plug being of softer material than the sleeve to allow for slight deformation of the knife-like edge to give a fluid-tight seal. The knife-like edge may be formed at the bottom of an annular shoulder 24 integral with the plug. The plug may be made tamperproof by being provided with a disc 12 (Fig. 3, not shown), which either seats in a groove in the plug or has projections 34 fitting within recesses 32 in lugs 25 formed within the plug, the lugs being used for removing the plug by means of a wrench after the disc has been broken. The plug may have a recess which faces inwardly, any pressure within the container causing the lower portion of the plug to expand radially outwardly into tight sealing engagement with the container sleeve. The sleeve may be made of nylon and have ribs 37 (Fig. 10, not shown) which engage the interior of the container to effect a tight seal or have a gasket interposed between the sleeve and the container. The plug may be formed of acetal plastics material.

Abstract: 1407215 Hydrometallurgical copper production DUVAL CORP 19 Sept 1972 [7 Oct 1971] 43419/72 Heading C1A [Also in Division C7] A process for the production of metallic copper comprises (1) oxidizing copper sulphide ore concentrates in a solution containing FeCl 3  until there is substantially complete solubilization of the copper content in the form of CuCl 2 , (2) reducing a substantial portion of the CuCl 2  to Cu 2 Cl 2 , (3) recovering metallic copper from the Cu 2 Cl 2  solution by electrolysis and (4) regenerating the solution from stage 3 for use in stage 1 with concurrent purge of excess iron and sulphate ions and other impurities. Steps 4 and 1 may be combined. A preferred arrangement is shown in Fig. 3. The CuCl 2  may be reduced to Cu 2 Cl 2  by the addition of copper-containing materials including the ore concentrate before oxidation, the final reduction may be carried out using Fe, SO 2 , Cu or Na 2 SO 3 . The solution throughout the process may contain NaCl, KCl, MgCl 2  or mixtures thereof preferably at levels near the maximum practicable on solubility grounds. The oxidation stage may have a temperature of 107-159‹ C. Sulphur may be separated from other residues. The reduction stage is preferably at 107‹ C. The process solution may be regenerated by contact with air or O 2 , preferred conditions with oxygen being 0-60 p.s.i.g. and 107-130‹ C.

Turnbuckle 8 allows adjustment of the shoe angle, a pin-and-slot connection 23 allows limited vertical motion of the shoe, and further vertical motion is accommodated by a spring 10 between bell-crank 7 and piston 12. Acoustic coupling between probe 3 and material 2 is thus maintained, thereby avoiding the generation of spurious echo signals. The supply of compressed air to cylinder 13 may be controlled by a magnetically-operated valve in turn controlled by a mechanical or photoelectric switch which senses the presence of material 2 at the test station. Water for cooling and ultrasonic coupling is supplied through respective tubes 4 and 5. Several probes may be arranged across the width of the test material.

Abstract: 1385220 Casting composite articles; blocking lenses ESSILOR INTERNATIONAL 27 Sept 1972 [29 Sept 1971] 44630/72 Headings B3F and B3D An apparatus for casting a holding block on to the convex face of a lens comprises a base-plate 1 provided with a circular seat 5 for the lens, a mould 12 having a flexible skirt 19, and a mould support 11 movable in relation to the base-plate from a position permitting observation of the lens along a sighting axis Z to a casting position in which the mould 12 is in direct contact with the convex face of the lens, the mould 12 being movable about two axes which are perpendicular to one another and intersect at a point 0 in, or substantially in, the plane containing the free edge of the skirt 19 and, in the casting position of the mould support, on the axis of the seat 5. The mould support 11 is rigid with a pintle 10 which may be rotated with respect to the base-plate 1 to permit the mould to be moved to and from the casting position. The mould 12 comprises a flat bottom 18 and a flexible skirt 19 which engages the lens surface when the mould is in the casting position. It is secured to a block 20 having a part-spherical upper surface 21, the centre of the sphere lying at the mould centre 0. The block 20 is connected by a shank 23 to a ring member 24 formed with a frusto-conical bearing surface 25 which engages a part spherical surface 26 rigid with the mould support 11. The movement of the block 20 is guided by a linkage 27 having one end pivotally connected to the shank 23 and its other end to a rod 33 rotatably mounted in a sleeve 34 whose axis 33a extends through the centre 0 of the mould. In use, the base-plate 1 is locked. in position in relation to the frame 2 of a centering device so that the axis of the seat 5 is coincident with the sighting axis Z of said device. The lens is then placed on the seat and adjusted to its required position relative to the image of a reference crossline. The mould support is now rotated about the axis of the pintle 10 until a rod 13.engages in a bore 14 and is then moved downwards until the flexible skirt 19 is pressed against the upper convex surface of the lens. The supporting arrangement for the mould is such that the mould automatically assumes its proper position with respect to the lens. In another embodiment, Fig. 4, the mould is carried by a semi-cylindrical block 36 which is rotatably mounted by means of balls 38 rolling in grooves 39 and 40 in a head 37 constituting a first section of the mould support 11. The head 37 is rotatably mounted about a shaft 44 rigid with a secod section of the mould support, the axis of the shaft 44 being perpendicular to that of the block 36 and intersecting the latter at the mould centre 0.
