Title: Improvements in method of, and apparatus for, manufacturing light conducting devices
IPC: C03B37/029
Filed: 1961-02-01
Abstract: 925,335. Light guides. A. ABBEY (American Optical Co.). Feb. 1, 1961, No. 3872/61. Class 97 (1). [Also in Group XXIII] A rod of heat softenable material of relatively high refractive index is mounted within a tube of lower refractive index and the two moved vertically through a heated zone to fuse the tube and collapse it on the rod under the influence of a vacuum maintained between them, the fused assembly then being drawn to a reduced cross-section to form a fibre which transmits light by internal reflection. In the form shown the rod 10 and the tube 12 are mounted by rubber rings 9, 11 in a holder 6 in a fused quartz tube 5 down which it may be moved by a rod 7 actuated by a lead-screw 22. The space between tube and rod is evacuated through a passage 12; the interior of the tube 5 also being evacuated, but less thoroughly, through a pipe 15. The tube and rod pass through a heater 17. After the tube has collapsed, the composite rod passes through a lower temperature heater 28 and is reduced, for example, to a square cross-section by rollers 30. These may be of graphite, protected by an inert gas fed through a pipe 36, or of titanium carbide. Adhesion with the glass may be prevented by a coolant circulated through passageways in the spindles and rollers. The re-shaped rod is then passed through a further heater 33 and drawn as desired.

Abstract: 808,733. Cutting-out presses. SCHWARZ, L. May 8, 1957 [Feb. 8, 1956], No.3888/56. Class 31 (1). [Also in Group XVII] In a press tool of the kind which forms a cruciform blank from a rectangular sheet by cutting away substantially rectangular cornerpieces, and presses the blank between a pair of formers after turning up the side margins to produce a tray, combined cutting and bending tools and at least one of the formers are adjustable as to size for producing different sizes of box or lid. The lower portion of the press tool comprises a former which may be domed and consists of four corner blocks 1, adjustably secured to a supporting block on the base-plate 12, and crossed interlocked strips 2, 3 which are interchangeable to alter the former's dimensions. Male cutting-elements 16 are adjustably mounted on the plate 12 and have apertures 15 adjacent their cutting-edges through which the waste cut-out corner portions are thrust by pillars 38 on the upper press tool portion. The upper tool portion comprises pillars 31 cooperating with sleeves 28 on the lower portion for locating purposes and has a former block 46 movable within a rectangular enclosure formed by combined bending and cutting tools 43, 45 in known manner. The tools 43, 45 are secured about a block fixed on the base-plate 30 from which block they are spaced by interchangeable packing strips 40, 41 and each consists of end portions bearing the cutting faces and an interchangeable central portion 42, 44. If the former 46 is flat-topped it may be made of adjustable dimensions but if domed, a different former is used for each box size. Plates 52 mounted on and spaced from the tools 45 receive and retain the uncut blank fed in laterally against stops 26 on the lower tool portion. After formation of the tray, the inner edges of the plates 52 strip it from the lower former as the upper tool portion rises. The formed tray is ejected laterally by the next incoming blank. A ring 32 carries heater elements (not shown) which facilitate shaping of the lid. The size of the upper and lower formers may alternatively be made variable by having a centre portion of fixed dimensions to which strips of various widths are secured externally and the bending and cutting tools may be likewise adjustable.

Title: Sheet metal forming
IPC: B21D26/02
Filed: 1974-01-28
Abstract: 1461821 Cupping UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 Feb 1975 [28 Jan 1974] 03894/74 Heading B3Q A metal blank 3, Fig. 1, is formed in a die cavity 4 by pressurizing oil 8, the cavity 4 being initially filled with oil 16 compressed by the blank and communicating through a duct 7 with a closed reservoir 15. If the oil 16 can be compressed enough to accommodate oil from the cavity 4, the blank may be cupped in a single step. Otherwise, relaxation of pressure on the oil 8 between cupping steps allows some of the oil 6 in reservoir 15 to flow through a non-return valve 17 thus facilitating the next cupping step. The oil lubricates the die. Larger cupping steps are possible with a secondary reservoir 30, Fig. 2, within the primary reservoir 15 and in which the oil 6 compresses a body of gas, another liquid an elastomeric material or (as shown) acts on a piston backed by a spring which is retained in the reservoir 30 by a pin 35. This supplementary device reduces the "stiffness" of the body of oil 6 during the first part of a cupping step. In another form, Fig. 3 (not shown), the die is mounted on a reservoir (40) for the oil (6<SP>1</SP>) above which is a space for gas (air), the reservoir resting on the floor of the chamber (41) for the pressurizing oil (8<SP>1</SP>).
