Abstract: 1,124,697. Axles. EATON AXLES Ltd. 28 Sept., 1966 [1 Oct., 1965], No. 43457/66. Heading B7D. [Also in Division F2] An axle mechanism is lubricated by lubricant picked up by the surface of a bevel planet carrier 41 and removed therefrom by a stationary director 45 of a non-abrasive plastics-like material, such as neoprene, nylon or rubber, which is chemically compatible with axle lubricant. As shown, a tandem axle arrangement comprises an interaxle differential 12 having side wheels 17, 18 driving a rear axle (not shown), and driving a front axle 11 via gears 25, 33 and a bevel gear 37 which meshes a ring gear 40 on the carrier 41 of a differential 39 for the front axle. The director 45 supplies lubricant to a chamber in a housing 9, whence lubricant is supplied to the interior of the carrier 41, to planet gearing for multi-speed axles if such is employed, and to the axle support bearings. Lubricant is also supplied from the chamber to the gear 33 and transmitted to the gear 25 from which some lubricant is slung into a channel 46 in the housing. From the channel 46 lubricant is led through a passage 50 in the housing and through passages in an input shaft 23 for the rear axle to the interaxle differential 12 and to bearings for the gear 25. A portion of the lubricant is again slung into the channel 46 by the differential 12. The rear axle arrangement is similar to that for the front, and it supplies lubricant in the same way. The housing 9 is formed by housing members 54, 55 which are bolted together and cover the interaxle differential and a portion of the forward axle mechanism 11. Member 55 is connected to a member 57 covering the differential 39 and forming part of the lubricant reservoir. Housing member 55 includes a conical wall portion from which project portions 58 supporting bearings for the forward axle shafts 43, axial forces exerted on the portion 58 by the axle shafts being transmitted directly to the conical wall portion to minimize bending of the housing.

Abstract: 1,197,687. Clay pigeon trap or launching device. P. CULAS. 17 Sept., 1968 [19 Sept., 1967], No. 44051/68. Heading A6D. A device for projecting into the air clay pigeons and other target projectiles comprises a curved tubular member into which the projectile to be launched is placed, said tubular member being closed at one end and open at the other and having means for admitting a compressed gas into the closed end, said tubular member being provided with a sunway of frictional material extending at least part way along its internal wall having the greatest radius of curvature and wherein the cross-section of the tubular member is such that the projectile is a sufficiently close sliding fit to prevent undue escape of the compressed gas, the coefficient of friction of the frictional material being such that a rotary motion is imparted to the projectile as it is launched. As shown in Fig. 1, the device comprises a rigid curved tubular member 1, its curvature being preferably elliptical, and the portion 2 of the member at its open end being straight. As shown in transverse section in Fig. 2, one wall 3 of the member is smooth and flat while the opposing wall 4 is internally profiled to fit the shape of the stepped face of the clay pigeon or projectile 5 which is a circular disc one face of which is flat and the other stepped. There is a small clearance between the stepped face of the projectile 5 and the wall 4 of the tubular member. The wall of the tubular member I having the larger radius of curvature is provided along its length with a strip 6 of frictional material which cooperates with a running edge of the projectile 5 during the launch of the projectile and cause it to rotate as it is launched. The closed end 8 of the member 1 is provided with an inlet valve 9 through which a compressed air or other gas can be admitted into the member 1. The valve 9 is adapted to open and close automatically. When the projectile 5 is inserted up to the end of the tubular member I as shown in Fig. I and the valve 9 is opened the projectile is forced to the open end of the tubular member at high speed, and at the same time rolls along the runway 6 so that it is also caused to rotate at a high speed. As a result of the gyroscopic effect thereby produced the path of travel of the projectile through the air is stable over the whole of its trajectory.

Waste gas containing harmful constituents e.g. fluorine sulphur dioxide or hydrogen chloride is forced by a blower 1 into a pipe 2 to which absorbent is fed from a hopper 4 by a distributor 3. The waste gas with the entrained absorbent enters the apex of a downwardly tapering conical separating vessel 5 in which a fluidized bed forms. A second similar but larger separating vessel 6 is in series with the vessel 5 and the fluidized bed therein is of finer particles. The waste gas and particles of absorbent pass into a cyclone 7. The residual reactivity of the absorbent is tested by a sampling technique involving e.g. measurement of temperature and/or conductivity or, where appropriate, CaO content. Depending on the test, the absorbent is either returned to the hopper or rejected through outlet 10. Two series connected separating vessels 12, 13 may, as shown, be connected in parallel with the vessels 5, 6. Water can be injected at 15 to increase the moisture content of the waste gas. Each separating vessel may have, in its outlet, a centrally disposed vertically movable tube to control the amount of absorbent in the fluidized bed.
