Abstract: 1444622 Press-blowing of stemmed glass articles A T RANSON 25 July 1973 35325/73 Heading C1M In the manufacture of a stemmed glass article, a charge (G) of molten glass is delivered to a parison mould (10) and pressed by a plunger 11 to form a parison P with a hollow upper portion and a solid lower end P<SP>1</SP>; the parison P is transferred by a neck mould 12 to a finishing mould 13 which includes a bottom plate 14 and in which the parison P is permitted to sag downwardly under the action of gravity without appreciable accumulation of glass on the bottom plate 14 and the hollow body of the parison is then blown to form a hollow bowl B and at the same time the bottom plate 14 is moved upwardly to form a base F connected to the bowl B by an intermediate stem portion T. Mould halves of mould 13 are mounted on carriers 20 pivoted on shaft 21 to open and close the mould 13 by links 22 on a head 23, an arm 24 of which is secured to a shaft 25. Shaft 25 has an arm 26 connected to a rocker member 28 by a link 27 and rocker member 28 is also pivoted to a portion (30a) of the apparatus movable round cam 30 and engaged by a cam follower 29, so that shaft 25 is oscillated to open and close mould 13.

Title: Arrangement for transmitting communicating currents with discharge tubes
IPC: H04B3/20
Filed: 1929-11-19
Abstract: 343,914. T w o - w a y repeaters. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 19, 1929, No. 35370. Convention date, Nov. 20, 1928. [Class 40 (iv).] When the mean potential of the grid of a valve is altered for control purposes, e.g. by an echo suppressor in a two-way telephone repeater, an impulse is produced in the output circuit and may have undesirable effects. The invention consists in neutralizing this impulse by means of an additional byepath coupling to the output circuit. In the repeater shown in Fig. 3, the valve V alone is used as an amplifier between lines L1, L2, but a second valve R neutralizes in the output circuit the effect of varying the control potential applied at A, B. In Fig. 2, the impulse generated in the valve V by operation of the echo-suppressor G is neutralized by the coupling U.

The mirror 16 has an ellipsoidal aperture 106, Fig. 2B. The central portion of the scene (i.e. a 1 degree cone) passes via the aperture 106 on to a photodiode or photo-multiplier 80. When the associated electronics are actuated by a switch 210 and a "measurement hold" is made, a L.E.D. 120 is actuated. The L.E.D.'s radiation passes through the aperture 106 of the mirror 16 and is seen in the centre of the scene by the viewer looking through the eye-piece 32. The lens 12 may be focused on the scene by means of a knob 54 which turns pulleys 56, 58 that move a belt 60 and connection member 62, 52. The mirror 16 comprises a substrate portion 100, Fig. 2B, having a coating of reflecting material 104, e.g. aluminium, that defines the aperture 106. Both sides are then coated 102, 102' with a layer of anti-reflection material.

Title: Method of recovering osmium
IPC: C01G55/00
Filed: 1934-12-17
Abstract: Osmium, in the form of its tetroxide, is extracted from materials containing it by means of a hydrocarbon or halogenated organic solvent, which preferably comprises carbon tetrachloride or benzene, but may also be methylene chloride, chloroform, pentachlorethane, chlorbenzene, brombenzene, petroleum ether, toluene, &c.  In applying the invention to osmium residues in the form of sulphide sodium osmate is first obtained in solution by treatment with caustic soda and chlorine, the solution acidified with hydrochloric acid, and the osmium tetroxide thus freed then extracted.  When starting with a mixture of the platinum group metals, the initial material is first heated with zinc, and the alloy so formed treated with sulphuric acid to dissolve zinc and leave the platinum metals in an amorphous state. The latter are heated with caustic alkali and a chlorate &c. and the product extracted with water to obtain sodium osmate and ruthenate in solution and leave a residue of the oxides of the other platinum metals.  The osmate-containing solution is acidified with hydrochloric, sulphuric, phosphoric, or acetic acid to form free osmium tetroxide which is extracted and a stable ruthenium salt. The tetroxide solution is treated with alkali to form alkali osmate, and a stable solution containing hypochlorite is obtained when the solvent is a chlorinated hydrocarbon containing free chlorine.  From the osmate, the metal may be obtained by reduction with sodium formate.  The ruthenium salt solution is made alkaline, saturated with chlorine, and then distilled as in a stream of chlorine to recover ruthenium oxide; or by collecting the distillate in an aqueous alcoholic solution of hydrochloric acid ruthenium chloride is obtained.  Osmiridium, crude platinums, and laurite (a sulphide of ruthenium and osmium) are specified initial materials.  Suitable apparatus for extraction with carbon-tetrachloride and benzene respectively is shown and described and a flow sheet included in the Specification.ALSO:Osmium is obtained by reducing a solution of an alkali osmate with sodium formate.
