Abstract: 1425258 Fuel oxidizing apparatus NISSAN MOTOR CO Ltd 24 Oct 1973 [27 Nov 1972] 49410/73 Heading F1L The invention relates to an apparatus for oxidizing fuel without the formation of nitrogen oxides, the apparatus comprising a housing 10 which defines a chamber 12 within which is rotatably mounted an oxygen absorbing porous wheel 14. A fuel inlet 16 and an air inlet 24 open into the chamber adjacent an end-face of the wheel, the fuel inlet and the air inlet being spaced apart circumferentially. An oxidized gas outlet 26 opens from the chamber adjacent the opposite endface of the wheel, the outlet 26 being aligned with the fuel inlet 16. A residual gas outlet 28 opens from the chamber adjacent the opposite end-face of the wheel, the outlet 28 being aligned with the air inlet 24. The wheel is operative to absorb oxygen from air introduced through the inlet 24 also to allow fuel introduced through fuel inlet 16 to be oxidized by the absorbed oxygen, the oxidized fuel passing out through outlet 26 and being mixed in duct 30 with residual gas discharging through outlet 28. The wheel utilizes oxygen absorbing materials such as iron, nickel, copper and/or vanadium. The discharging gas mixture may be utilized to drive a gas turbine 32. The wheel 14 is driven either at constant or variable speed. In the embodiment the fuel inlet is precombustion chamber provided with an igniter 22.

In an assembly of shelf or cabinet units 1 the latter are independently movable on tracks 101 between fixed end units 3 so that a passageway 4 is formed between adjacent units, the units 1 each carrying a pair of freely rotating drums or sprockets 7 which are continuously engaged with opposing longitudinal runs 11, 12 of an endless motor driven belt or chain 6 arranged with its runs 11, 12 at the same height above the ground, and the assembly including means for selectively and drivingly coupling one or other of the sprockets 7 to its associated unit 1 whereby the latter may be moved along the tracks 101. In one embodiment (Fig. 3), the couple means comprises a two-armed lever 15 pivoted on a shaft 16 by hand lever 20, the lever 15 carrying vertically guided depending pins 14 which are selectively engaged with a sprocket 7 to lock the latter relative to the unit 1 which is then carried along by the associated run of the chain 6. The drive motor is actuated by a switch 106 engaged by an actuator 105 on the hand lever 20. A stop bar 21 mounted on the end wall 19 of the unit 1 moves with the lever 20 and prevents the lever 20 being moved in a direction away from an existing passageway 4 by end abutment with the stopper 21 of an adjacent unit 1. In an alternative embodiment (Fig. 5), the sprocket 7 is vertically movable with a shaft 26 housed in a fixed sleeve 27 by means of an eccentric 29, the coupling of the sprocket 7 to the unit 1 being provided by clutch surfaces 25 on the sprocket 7 and sleeve 27. The clutch surfaces 25 may be toothed or may be of the friction or electromagnetic type. In a further embodiment (Fig. 12) a three-armed lever 130 carries the coupling pins 14 and engages the stop bar 143, the lever 130 being operated through a rotary shaft and a foot lever. An auxiliary floor 38 (Fig. 2) is mounted between adjacent units 1 and is spring urged to the position shown, the floor 38 carrying supports or leaf springs 41 which engage ground tracks 42 when the floor 38 is horizontal, e.g. when a person is standing thereon, whereby the circuit to the drive motor is automatically broken. Outwardly urged ledges 120 are accommodated in recesses in the end walls 19 and serve to close the gap between adjacent units 1, and the ledges 120 may be associated with switch means to break the drive motor circuit when engaged by a part, e.g. hand, of a person protruding to within the passageway.

Abstract: 1,164,820. Lubricating; toothed gearing. BRITISH UNITED SHOE MACHINERY CO. 18 Nov., 1966 [19 Nov., 1965], No. 51671/66. Headings F2A and F2Q. A lubricating device for bearings &c. comprises a multi-layer assembly of non-absorbent heat-conducting durable material of discontinuous construction with grease packed around and between the layers of the material and in the interstices of the construction thereof, said grease being capable of releasing lubricating fluid upon a rise in temperature of the bearing &c. The material may be metal in the form of a mesh, which may be provided with a selvedge; may be coiled; and may form a central reservoir for the grease. In an embodiment, a cartridge comprising a grease-filled coil of non-absorbent heat-conducting material is clamped within a deflectable gear 18 of an actuator 12 by means of a plate 32 and a screw 36, the latter screwing into a shaft 26 and having a tubular spacer 34 thereon. The actuator 12, which is of the harmonic drive type, comprises a rigid circular spline 14, having internal teeth 16; the deflectable gear 18, having a lesser number of external teeth 20 arranged to mesh with the teeth 16 of the spline 4 at spaced circumferential localities; and a wave generator 22 which, with its bearing 24, generates a continuous wave of radial deflections in the gear 18 and hence effects tooth interengagement to produce a rotary output in one of two shafts 26, 28, the other of which serves as an input member. When the bearing 24 becomes heated, the heat is transmitted to the cartridge and is therefore conducted to the grease 44 within said cartridge. Oil is released from the grease and is conveyed to the bearing 24. The cartridge may be periodically replaced or repacked with grease.
