Abstract: 1421669 Preparation of steels CREUSOTLOIRE 15 Nov 1973 [28 Nov 1972] 53141/73 Heading C7D In the production of metals or alloys, e.g. mild steel, stainless steel, in an electric furnace, O 2  or an 02-rich gas surrounded by a protective agent, e.g. fuel oil, is blown below the surface of the charge during an oxidation stage by a consumable tuyere in the hearth or wall of the furnace. The oxidizing gas and protective agent are replaced by a neutral or reducing gas, e.g. Ar, N 2 , during subsequent reduction, desulphurization or deoxidation. In addition air may be supplied through both conduits of the tuyere, before the oxidation stage, to activate smelting. During the reducing phase pulverulent CaO, Si or C is contained in the gas, and during oxidation, the O 2  or 02-rich gas contains a diluent, e.g. water vapour, neutral gas or atomized water. In the Example, mild steel is produced from steel scrap and anthracite. The preparation of stainless steel from Cr steel scrap and ferro alloys is also referred to.

Abstract: 1338405 Aircraft indicator instruments SPERRY RAND CORP 10 Nov 1970 [10 Nov 1969] 53389/70 Heading B7W [Also in Divisions G1 G5 and H2] A multiple indicator instrument comprises a housing 35, a yoke member 37 rotatably mounted within the housing 35 about a first axis, a mask 12 attached to the yoke member 37 and having an aperture therein, a display disc 45 which has a face with a plurality of display indicia 50-57 thereon and which is rotatably supported by the yoke member about a second axis 46 normal to the plane of said face and parallel with the first axis, with the face being adjacent and behind the mask in such a manner that the indicia are selectively viewable through the aperture when the instrument is viewed from the front, and drive means 62 associated with the disc 45 and operative to effect rotation of the disc with respect to the mask about the second axis. The aperture is one of two apertures 15, 16 in the mask 12. The drive means 62 comprises a permanent magnet 65 attached by a shaft 64 to the display disc 45 and a housing fixed to the yoke member 37 and carry circumferentially spaced electromagnets 70-77 respectively energizable to shift selected indicia 50-57 into view through the apertures. Each electromagnet may be connected to one output circuit 81, 82, 83, 84,85 or 90 of a logic circuit of an aircraft instrument landing system (I.L.S.) and each logic circuit provides a signal to the respective electromagnet only when the exact information depicted by the corresponding indicium is received by the I.L.S. When the selected electromagnet is energized, the North pole of magnet 65 is attracted to the selected electromagnet and rotates the disc 45 so that the corresponding indicium is viewed. A permanent magnet 80 having a field strength weaker than that of the electromagnets attracts magnet 65 when no electromagnets are energized (i.e. no information is being received by the I.L.S.) and causes blank indicia 53, 57 to align with the apertures 15, 16 of the mask. The mask 12 has mounted thereon pointers 13, 14 which indicate a selected course on an annular compass card (22), Fig. 1 (not shown), surrounding the mask and rotatable relative thereto. An indicator bar 17, Fig. 2, is provided to indicate how far the aircraft has deviated from the selected course indicated by the pointers 13, 14, scale dots 21 being provided in this respect. Other indicia may be provided on the bezel, Fig. 1 (not shown), of the instrument.

Abstract: 1,150,498. Attracted armature relays. BABCOCK ELECTRONICS CORP. 24 Nov., 1967 [5 Dec., 1966], No. 53528/67. Heading H1N. An electromagnetic relay has a pair of back stops for its armature arranged to provide oblique surfaces which are engaged by the armature and have opposite twisting effects on the armature. The centrally pivoted armature 18 of Fig. 1 is biased so that its ends engage stop projections 46 of a base 30. The corner of each surface 50 (51) of the armature engages an oblique surface 46 of the stop, and the armature is driven against a shoulder (not shown) of its pivot shaft 26 to dissipate kinetic energy whilst the twisting effects at the opposite ends of the armature are in opposition. The inclination of the surfaces 50 (51) to the longitudinal axis of the armature results in a tendency to compress the armature and further dissipate energy. In Fig. 10, an armature 63 engages bent ends 81, 82 of a stop 64.

A closure for a preserving jar 14 having a peripheral bead 12 comprises a lid 3 in which a sealing ring or sealing compound 13 is placed, the sealing surface 2 of the rim 1 of the jar forming a zone of a sphere and co-operating with a sealing surface 4 of the lid. An annular groove 8 has an upper wall 9 which makes an angle of not less than 45 degrees with a plane perpendicular to the longitudinal axis of the jar, the groove being shaped in this manner to prevent splintering of the lid when an opening tool is inserted in the groove. Grooves 11 in the lid and 10 in the rim of the jar assist in making a vacuum tight joint. The lid is made of glass but in a modification a metal lid forms a mechanical closure for the jar, however the metal lid may be adapted to form a vacuum closure. The lids may also be made of plastics material.
