Abstract: 610,856. Electric indicating systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 29, 1946, No. 9738. Convention date, April 3, 1945. [Class 40 (i)] In an aircraft attitude indicator, roll and pitch are detected by a stabilised device, such as a gyroscope, and rolling movements are transmitted to an indicator by an electric remote control device. Pitching movements may be indicated by a mechanical connection. The arrangement enables the indicator to show a representation of the aircraft in flight as viewed from a fixed point, thereby assisting the pilot's natural reactions in correcting. The gyroscoperotor spins on a vertical axis A, A in a casing 11 and is mounted on a transverse axis on pivots 12, 12 in a gimbal ring 13 supported on longitudinal pivots 14, 14. One pivot 12 is extended to carry an arm 18 so as to raise or lower the indicator 5 relative to a window 7, carrying a fixed horizon line 6, to follow pitching movements. One pivot 14 carries a permanent magnet 29 so as to rotate it within a wound annular stator 22 in response to rolling movements. This stator is electrically connected to a wound stator 30 to influence a permanent magnet 35 on a spindle 16 in known manner. This spindle carries the indicator disc 5 to rotate it to show any banking motion. The electrical connections of the system, (see Fig. 5, not shown) are such that the two stator windings are fed in parallel from a common A.C. supply and are also interconnected by three common leads joined to three equally-spaced points on each.

Abstract: 1,193,237. Reducing ores. INTERNATIONAL NICKEL CO. OF CANADA Ltd. March 4, 1968 [March 6, 1967], No. 10414/68. Heading C7D. [Also in Division C1] Complex ores (i.e. containing oxides of two or more metals) are pelleted, the pellets are mixed or coated with a non-fluxing refractory oxide (e.g. alumina, magnesia or titania, or olivine, asbestos, peridotite or forsterite containing no more than 7% iron but preferably unweathered serpentine) which will react therewith during heating to form an oxide solid solution coating with a softening point above that of the ore and above the heating temperature, to prevent sticking of the pellets and then heating the pellets in a reducing atmosphere to reduce at least part of the oxide content of the ore and to coalesce the metal. The reduction may be accomplished solely by means of the furnace atmosphere but it is preferred to include a carbonaceous reducing agent in or with the pellets, also an agent (e. g. SiO 2 ) may be included in the pellets to reduce the viscosity of the ore. The metal values may be recovered from the treated ore by magnetic separation and sulphur, as such or in a combined form may be included in pellets of Ni containing ores (e.g. laterite) to increase the size of the Ni particles produced.

Title: Improvements in thermal electric switches
IPC: A61F7/00
Filed: 1943-07-02
Abstract: 573,156. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. July 2, 1943, No. 10752. Convention date, July 3, 1942. [Class 38 (v)] A slow make-and-break thermal switch suitable for incorporation in the heating circuit of electrically-heated blankets, comprises normally-closed contacts 17, 18 carried on similarly-deflecting main and auxiliary bimetal strips 15, 19, respectively. The strip 19 is of relatively low thermal mass and riveted at 20 to a support 14 having a dent 21 whereby the strip 19 is stressed and does not move down until a temperature is reached which is above that required for strip 15 to open contact 17. In opsration, if overheating occurs, strip 15 moves down and opens the circuit, whereupon the blanket cools. If arcing occurs in reclosing, the strip 19 heats more rapidly than strip 15 and deflects downwards to reinforce the contact, the action being intensified by the current being now directed to the strip 19 itself. However, as the blanket and strip 15 continue cooling, the latter overcomes strip 19 and forces the contacts back to the normal position shown, whereat normal heating conditions are resumed. Cases.-To enable the blanket to be washed, a watertight casing comprises a copper tube 22 with asbestos liner 23 and rubber end plugs 25 apertured to receive tightly the end connections 11a, 11b which are knotted and soldered to the support 14 and strip 15. To prevent damage to the switch by distortion of the container, the switch and the insulating support 16 are made a loose fit in the latter.
