At temperatures up to 400C., a layer 25-5000 Angstroms thick is formed, said layer consisting of an outer stratum rich in copper oxides and an inner stratum rich in oxides of said first element. At temperatures of 400 - 850 C. a second layer at least 50 Angstroms thick is formed beneath the two-stratum layer, said second layer containing a discrete dispersion of a complex oxide including at least one of the said first and second elements. The outer stratum is generally coloured, provides little or no oxidation resistance and is therefore preferably removed e.g. by dissolution in dilute H 2 SO 4 . If subsequently the inner stratum is removed, as by buffing, etching, pickling or mechanical forming, continued protection is afforded by the second layer.

Patent GB-1029456-A (GB)
Title: Process for the production of gases of high calorific value
IPC: C10G47/00
Filed: 1964-10-28
Abstract: Methane-rich gases of high calorific value are made by continuously introducing finely divided solid or liquid carbonaceous fuel, e.g. coal dust or fuel oil, and hydrogen into a reaction chamber to suspend the fuel in the hydrogen at elevated pressure, e.g. 50 to 150 atmos. absolute, for reaction at temperatures in the range 700 DEG to 1000 DEG  C.  The hydrogen is preferably preheated by heat exchange with the product gas.  The hydrogen may be made by catalytically cracking the product gas with steam, or by gasifying a solid or liquid carbonaceous fuel with oxygen (air) with or without steam, the-CO being subsequently converted to CO2 which is, preferably, washed out. Where solid fuel is used, it is entrained by a current of hydrogen; where liquid fuel is used, it is introduced into a current of hydrogen through nozzles.  Two specific examples are described.

The cage 4 is fixed to the driving member 2, and the springs are leaf springs which extend into bores 10 in the pivoting members 3. In an alternative construction the pivoting members are rotated 180 degrees from the position shown and the cage 4 is attached to the outer ring, the inner ring here being the driven member into contact with which centrifugal force rotates the members 3. To enable a smooth engagement of drive not all springs 5 have the same resilience so that some engage before others. An application is described wherein the freewheel clutch is installed in parallel with a centrifugal clutch between an engine and gear-box, to permit engine braking on overrun and push (or downhill) starting of the vehicle, where the engine is driven through the gear-box.

Abstract: 948,541. Beacon lights. GENERAL ELECTRIC CO. Ltd. Dec. 10, 1962 [Dec. 22, 1961], No. 46069/61. Heading F4R. A position-indicating arrangement comprises an opaque enclosure containing one or more light sources and having a pair of openings through which light can pass, two sets of parallel louvres disposed so that light from each of the openings passes between a respective set of louvres, and a colour filter disposed in one of the light paths, the two sets of louvres being relatively inclined so that light emerges from them in the form of two relatively inclined light beams of different colours overlapping at a boundary plane. Fig. 1 shows an apparatus designed to assist the landing of an aircraft on the deck of an aircraft carrier and comprising a casing 1 divided into two compartments of a partition 2, each compartment containing a number of lamps 9 disposed in parabolic reflectors 7. The reflectors in the upper compartment may be inclined upwards at an angle of about 4 degrees. At the open sides of the compartments are sets of parallel louvres 10 and 11, the louvres 11 being inclined 2 degrees downwards and the louvres 10 being inclined about 8 degrees upwards with respect to the louvres 11. A red filter 12 is arranged in front of the louvres 11 and a light blue filter 14 may be arranged in the other light path to improve the contrast in colour. Thus, an observer in an aircraft on a correct glide path A will see a pinkish light as the beams overlap, whereas above or below the correct path he would see a white or a red light. Transparent plates 15 provided with vertical flutes spread the light beams horizontally, and, if desired, some or all of the reflectors 7 may be mounted on vertical pivots to allow the horizontal spread to be increased. Reflection from the lower surface of the upper set of louvres may be reduced by coating with a dark matt paint or by applying a lining, for example of expanded aluminium sheet; the upper surfaces of the lower set of louvres may be treated similarly. To reduce the intensity of the beams for night use, two movable screens are provided in each compartment. The upper screen 16 in the upper compartment is an opaque metal sheet and the lower screen 17 is a heavy blue filter. In the lower compartment the upper screen 21 is an expanded metal sheet and the lower screen 22 is an opaque metal sheet. The intensity may also be varied by variation of the current through the lamps.
