Abstract: 728,176. Aircraft undercarriages. DOWTY, G. H. Jan. 26, 1954 (Jan. 30, 1953; March 4, 1953], Nos. 2778/53 and 6044/53. Class 4. [Also in Groups XXXII and XXXIV] The wheeled undercarriage of an aircraft is provided with friction slipper brakes 30, 31, as shown in Fig. 2, hinged to the end of an extendible mounting, comprising the plunger 36 and cylinder 33, which is operated to apply the slipper to the ground from the retracted position, as shown dotted at 31<SP>1</SP>, after the aircraft has become groundborne. The shoe 30, 31 is hingedly coupled to the lower end of lever 28, pivoted to the wheel mounting, 21, 26, and is linked to the end of plunger 36 by an eyebolt 44. The shank 45 of which passes through a lug 46 on the lever 28, rubber blocks 49 being fitted on each side thereof to provide the resilience necessary for the shoe to turn on the hinge pin 42 sufficiently to maintain fore and aft contact over irregular ground surfaces or when the aircraft changes attitude. A rubber block 53 is also fitted between the shoulders 51 and 52 to maintain transverse contact. In the arrangement shown in Fig. 6, the invention is applied to an undercarriage having a suspension lever 62.

An alkaline accumulator having electrodes of agglomerated metal particles impregnated with active material is provided with separators each comprising three layers, the outer layers being of high permeability, and the middle layer of low permeability. The layers may consist of gels having different permeabilities, or the middle layer may be of regenerated cellulose, the outer layers consisting of non-woven fabrics, e.g. fibres united by a binder. The layer in contact with the positive electrode may be made of a cellulosic non- woven fabric, the layer in contact with the negative electrode being of a non-woven synthetic resin fabric, for example a fabric made from vinylic material fibres. The three layers may be united by sewing, and they may be folded in concertina fashion. The electrodes may comprise perforated metal sheets coated on both sides with sintered nickel particles impregnated with nickel hydroxide with or without cobalt hydroxide, and cadmium hydroxide. The stack of electrodes and separators is forced tightly into a casing and impregnated under vacuum with a solution of potassium hydroxide. The cellulosic parts of the separators swell and put the stack under pressure. No gas is evolved during charging, but when fully charged the battery liberates gas and the voltage rises sharply.

The cams and levers may be duplicated, and the heald-frames may be connected in pairs by straps &c. passing over pulleys mounted above the heald-frames, which are guided in a slot m ; or they may slide up and down fixed pillars. In a second arrangement, two heald-frames provided with racks are operated by one cam and one tappet-lever, which is connected by a pin-and-slot arrangement to one of the racks. Both racks mesh with a pinion or pinions, whereby the motion of one heald-frame is transmitted to the other. In a third arrangement, healdframes operated by respective cam-controlled levers, which may be pivoted on the same shaft, are connected by chain and sprocket-wheel, or band-and-pulley gearing situated below the heald frames. In a fourth arrangement, cam-levers g, g<1>, Fig. 4<A>, fulcrumed respectively at i, j, have bowls &c. r, r<2> working in reverse positions of the groove in the cam e. In a fifth arrangement, a vertical lever operated by a cam on the main shaft controls two heald-frames by being connected thereto through lever mechanism including a toggle-lever device. In a sixth arrangement, two cams mounted on the low-shaft operate two upper and two lower levers, which are mounted on one shaft and operate four heald-frames, pairs of which may be connected above by chain-andpulley gearing. In another arrangement, the heald-frames h, h<1>, Fig. 7, are operated from levers 15, 16, 17, 18 pivoted at 19, 20<a> and having bowls 20, 21, 22, 23 engaging grooves in cams e, e<1> mounted on a shaft f<1> driven by bevelgearing from the low-shaft. The levers are connected to both sides of the heald-frames by links, of which only the Inks 24, 25 on the left are shown. In this arrangement, cam-paths may be formed in each face of a tappet. A further arrangement is described wherein cams mounted on a shaft, situated below but not central of the heald-frames, operate double-ended or compound levers. One end of each lever is linked to one side of the heald-frame, and the other end is connected bv links and a bell-crank to the other side of the heald-frame. In some of the arrangements, the operating-cams &c. may be mounted on a sleeve on the main shaft, and may be driven by wheel, chain, or other gearing. In the chain- and-pulley gearing used for connecting the healdframes, the power of a pulley may be increased by attaching intermediate pulleys to the chain sections.
