Title: Driving mechanism for driving wheels, which are mounted on swinging axles
IPC: B60K17/16
Filed: 1925-09-19
Abstract: 240,451. Osterreichische Waffenfabriks Ges. Sept. 23, 1924, [Convention date]. Differential or balance gearing is combined with universal or like connections to the vehicle part axles, which connections have a common centre at the centre of the differential. The differential casing 3, Fig. 1, is journaled in fixed bearings 4 and in turn supports the side wheels 7 which are driven differentially from planet pinions 6. The part axles 13 are universally jointed inside the two wheels 7, one to each. For this purpose two cross-slotted intermediate members 11. Fig. 5, are supported upon a central ball 12, back to back. Each wheel 7 has an inwardlvprojecting rib 8, Fig. 3, which works in one of the crossed slots 9, while a similar curved rib or fork 14 upon the end of each axle 13 works in the other crossed slot 10. The axle tubes 15 have cylindrical joints 15<a> allowing the axles to swing. In a modification. the cross-slotted intermediate members 11 are arranged outside the differential casing, the central ball being dispensed with. As shown in Fig. 6, the axles 13 are adapted to swing only in a plane at rightangles to the plane of the secton in cylindrical bearings 15<a>. The intermediate members 11 rest against the inner surface of the spherical differential casing 3 and are driven positively by extensions or ribs 8 of the wheels 7 at the rear. The members 11 are engaged directly by the forks 14 on the axles 13.

Abstract: 156,307. Drayton, T. J. B. Sept. 26, 1919. Spray carburettors. - A suction-actuated main air valve 1 carries on its stem 4 an adjustable inclined plate 9 on which bears one end of a bell-crank 7, the other end engaging directly a fuel valve 8. The lower end 2 of the air-valve stem moves in a tube 3 and acts as a dashpot; the valve is prevented from turning by a projection 5. A long nut 11 in the end 2 is movable by a graduated dial 12, and bears on the plate 9, so that the relative movement of the fuel and air valves may be varied; as the bellcrank bears on a sleeve 14 on the fuel valve, a second adjusting means is provided. The float chamber 16 is closed to the atmosphere except through a controllable port 20, Fig. 1, and is connected to the induction pipe 22 by a channel 21; the flow of fuel is therefore dependent on the engine suction. The fuel leaves the float chamber by a hole 25 past the valve 8 to a tube 26, which leads to the fuel nozzle 28 placed in a small mixing chamber; additional air enters between the coned tubes 33, 34, and the mixture passes through the exhaust heated pipe 29 to an annular passage 36, which is connected with the main induction pipe by holes 39. The rich mixture passing through these holes is added to the main air supplied past the valve 1. A coned ring 15, which is replaceable by rings of various inclinations, forms with the valve 1 a constricted passage for the main air.

A rechargeable hybrid fuel cell battery, e.g. of the Zn/air type, comprising a plurality of individual cells each with a counter-electrode 23, e.g. a stainless steel mesh between an oxygen electrode 12 and negative electrode 11, e.g. zinc is charged by connecting the negative and counter-electrodes to a D.C. source whilst supplying gas under pressure to the space between the oxygen and counter-electrodes to electrically isolate them. Preferably, the gas used for isolation is the gas supplied to the oxygen electrodes during discharging. As shown, during discharge electrolyte is circulated via inlets 21 and outlets 22 into chambers 16, 17 separated by porous membrane 18, and air is supplied to chamber 13 via 14, 15 of the oxygen electrode. For recharging electrodes 11 and 23 are connected to a D.C. source and the electrolyte containing the discharged ZnO particles is recirculated. The pressure in chamber 13 is increased so that air flows through electrode 12 into chamber 17, thus isolating electrode 12 from counter-electrode 23. The flow of air and electrolyte through the cells during discharging and charging is controlled by a system of valves and pumps. In a modification the electrolyte is not circulated, but remains within its individual cell, a reservoir being provided for storing electrolyte displaced by the air during charging.

Abstract: 1,013,821. Aircraft undercarriages. DOWTY ROTOL Ltd. June 28, 1962 [July 5, 1961], No. 24310/61. Heading B7G. An aircraft has one or more main landing gear components below its central longitudinal axis and outrigger components on opposite sides of this axis, the or each main component 10, 11 having liquid-filled chambers 21, 24 and 16, 22 connected by valve 27, 34 permitting flow between the chambers during normal shock absorbing movements of the component, and a control 36 which closes valve 34 during take-off to hydraulically lock the chamber 16, 22 to prevent extension of the component 10, 11, the control 36 acting in response either to a reduction of load sustained by wheel 12 below a certain value and as sensed by pressure switch 44, or to an increase in ground clearance beyond a given value and as detected by a ground feeler, Fig. 2, not shown. Non-return valve 27 permits flow from chamber 24 to 16 and a normally open valve 34 allows flow from chamber 16 to 24 through a recoil control orifice 32; a free piston 13 separates liquid in chamber 16 from air in chamber 15. Before take-off, e.g. of a V.T.O.L. aircraft, the pilot closes a switch 43 to open valve 39 to supply compressed fluid to, and so close, valve 34; as lifting power increases the load supported by component 10, 11 decreases but it does not extend so keeping the outrigger components on the ground. As the lift approaches the static weight of the aircraft, pressure in chamber 21 falls sufficiently to open pressure switch 44 to de-energize solenoid 41 permitting valve 39 and hence valve 34 to open which allows incremental extension of the leg until switch 44 is again closed by pressure in chamber 21 rising, and so on.
