Patent GB-768795-A (GB)
Title: Fabrication of rhenium
IPC: C22B61/00
Filed: 1955-04-21
Abstract: A method for fabricating rhenium metal comprises subjecting the rhenium to very small cold work reductions with intermediate anneals, and then subjecting the metal to more severe cold-work reductions with intermediate anneals until the desired fabrication is acheived. Rhenium bars of square or rectangular cross section prepared by pressing, presintering and sintering rhenium metal powder are worked into octagonal cross section by flattening the corners by hammering and then annealing in the temperature range of 1600-1800 DEG C. for 20 to 40 minutes.  Both steps are repeated once or twice to effect a total reduction of about 12 per cent on the diagonal length of the bar.  The original faces of the bar are then smoothed by cold rolling with negligible reduction in thickness or area and the edges of the bar are cold rolled.  Two or three such operations, with intermediate annealing as before, provides an octagonal bar and exects an additional 5-8 per cent reduction in the length of the diagonal per cycle.  Next, reductions of 10-20 per cent in cross sectional area per cold-working operation are effected although a number of cold swaging steps, each producing 10-20 per cent area reduction and with intermediate annealing at 1600-1800 DEG C. for 50-130 minutes, may be used.  If wire is to be made from rhenium bar, cold drawing operations after a few swaging operations to reduce the area by 10-20 per cent and with intermediate anneals for 50-130 minutes at 1600-1800 DEG C. are permissible.  For producing rhenium sheet the octagonization step is omitted and the hammering is effected along the edges and sides of the bar followed by annealing for 20-40 minutes.  Cold rolling is then performed to reduce the thickness of the bar by about 2 per cent per pass, each pass being followed by annealing as hitherto.  These rolling and annealing operations are repeated about five times to obtain a total thickness reduction of about 10 per cent.  Finally, heavier cold rolling passes of about 10 per cent reduction per pass followed by annealing at 1600-1800 DEG C. for 110-250 minutes reduce the bar to the desired sheet thickness.

Title: Optical inverting systems
Inventor: BURCH JAMES MORRISS
IPC: G02B27/14
Filed: 1966-03-16
Abstract: 1,178,973. Prism systems. NATIONAL RESEARCH DEVELOPMENT CORP. March 16, 1967 [March 16, 1966], No. 11615/66. Heading G2J. An optical system which divides a beam into two, and inverts one half, is used to convert a beam into two beams which are positioned symmetrically with respect to a straight line and thus can establish a line of symmetry which may be used as in Specification 1,178, 971 to align machine bearings or other adjustable parts of a structure. As shown, Fig. 1, the optical system is formed from two identical transparent blocks 11a, 11b, having square faces of side s and a thickness t which is one half of s. From mid points of the appropriate sides, portions are cut off, as shown, to form faces 12a, 12b and 13a, 13b, respectively, the two blocks being identical, but block 11b being reversed and turned through 90 degrees relative to block 11a, before being so cemented thereto that the two blocks form a cube, apart from the bevelled faces. The faces 12a, 12b are rendered semireflecting, and right angle prisms 14a, 14b are cemented thereto. The vertical face of block 11a, seen in Fig. 1 can be considered to be divided into four quadrants, lower right (L.R. 11a), lower left (L.L. 11a), upper right (U.R. 11a), etc. and similarly for prism 11b. Roof prisms (15, Fig. 2 not shown) which have their ridges removed are placed respectively with their effective ridge lines diagonally across the top of the cube, prism 15a, and one side thereof, prism 15b. Thus using the above terminology, light entering at LR 11a is reflected upwardly by surface 13a to semi-reflecting surface 12a. The partial beam which passes therethrough goes through prism 14a to prism 15a. It is thus transferred from quadrant U.R. 11a to quadrant U.L. 11b and passes downwardly to be reflected at semi-reflecting surface 12b and surface 13b. The partial beam which is reflected at surface 12a passes through quadrant U.L. 11a and is transferred by prism 15b to L.L. 11b (i.e. prism 14b) and passes through semi-reflector 12b to be reflected at surface 13b. The two beams passing out from surface 13b have an axis of symmetry which is aligned with the incoming beam. Surfaces 13a, 13b may be at different angles or one or both may be omitted if the axis of symmetry is to be at an angle to the incoming beam.

Filed: 1968-03-11
Abstract: 1,222,119. Coated glass bodies. GLAVERBEL. 11 March, 1968 [27 April, 1967], No. 11797/68. Heading C1M. A coated vitreous, vitrocrystalline or ceramic body is chemically strengthened by ionexchange through the coating between a liquid or gaseous medium and the surface-layers of the body, so producing compressive stresses in said surface-layers; the coating layer is, or is converted during or after the chemically strengthening to, an at least partially crystalline coating with surface hardness greater than that of the coated surface. The coating layer may result from the reaction in situ of constituents applied separately to the body. The final chemical composition of the coating may result from a reaction during the ion-exchange treatment between a coating constituent, present before ion-exchange, and another substance. Crystallization-promoters may be used. The coating may contain Al, Zr, Si, or Ti, and crystallization-promoters may be Li, Ti, Mn, Mg, Co, Cu, Ni, Zn, Cr. Fe, Ca, rare earths, halogens, Cd, Bi, Ni, Al, or water-vapour. The final coating may comprise at least one crystalline phase formed by: Al 2 O 3  (corundum), SiC, SiO 2 , ZrB 2 , TiN, TaC, ZrC, TiC, A1B, B 1 C, TiO 2 , ZrSiO 4  (zircon), Al 2 Be 3 Si 6 O 18  (beryl), or Al 2 SiO 3 (F.OH) 2  (topaz). The promoter may be added to a molten saltbath used for the ion exchange, either as such, or as compounds, e.g. sulphates, chlorides, or oxides. The coating may be performed by vacuum deposition, cathodic sputtering or hydrolysis. The body may be of glass formed from silica, soda, lime, and/or feldspar. Two exemplified bodies comprise, in wt. per cent: SiO 2 , 72.4/72.9; Na 2 O, 13.7/9.8; CaO, 12À0/0À9; Al 2 O 3 , 1.9/6.2; K 2 O, -/0À1; B 2 O 3 , -/10À4. The ions exchanged may be alkali-metal ions, e.g. K<SP>+</SP>, Cs<SP>+</SP>, or Li<SP>+</SP>, which are present in a molten salt-bath, e.g. of KNO 3 , OsNO 3 , or LiNO 3 . The ion-exchange may be promoted by a direct or alternating electric field, e.g. of 60-200 v. The exchange may be promoted by use of a substance which weakens the diffusion-barrier, e.g. by countering the diffusion-inhibiting effects of ions which diffuse into the ion-exchange medium from the body; such substances include halogens, alkaline earth metal ions, e.g. Ca<SP>++</SP> or Mg<SP>++</SP>, and substances which form complexes with ions migrating from the body, e.g. Fe, Ni, NH 4 <SP>+</SP>, CN-.
