[Class 108 (iii)] [Also in Groups XXXIII and XXXI] A resilient mounting for engines of motor vehicles and aircraft includes rubber blocks 3, 4, 5 inside a frame 2 disposed substantially in a plane containing the centre of gravity of the aircraft and carried from the vehicle or aircraft by a framework surrounding the rear part of the engine. In one form, the frame 2 is mounted on the fuselage 6 by struts 7, 8, 9. The resilient mountings more remote from the centre of gravity of the engine may be made more yielding under stress than those nearer the centre of gravity. The struts 9 may be omitted or be hinged to the fuselage. In a modification, the frame 2 is made in sections each connected to the resilient mountings and connected to the fuselage by hinged struts. A cowling may surround the engine and this may be formed in sections corresponding to the sections of the frame 2 and further provision may be made for relative movement between the forward and after portions of the cowling. The mounting may comprise a rubber-block 15 bonded to plates 22. The plates 22 may be formed with eyes to facilitate securing to the engine or mounting. This arrangement facilitates replacement or changing the characteristic of the mounting.

Filed: 1928-05-21
Abstract: 315,517. Wake, A. E. J. May 21, 1928. Sand and the like, distributing on wheel tracks. -Sand or similar material is automatically distributed in front of the wheels of a mechanically propelled road vehicle, when a skid occurs, by the resultant difference in peripheral speed between a revolving element associated with the driving wheels and a second element driven at a speed proportional to that of the engine. In the construction shown the second or driven element J is constituted by a wheel driven from the front wheels by a flexible shaft L and supported on a pivoted lever Q in such a way that it is normally pressed into contact with the rear brake drum K. Owing to its rotation, the wheel J tends to ride -upwardly on the brake drum, but the greater peripheral speed of the drum normally maintains the wheel in the position shown in Fig. 1. When, however, a skid occurs, the speed of the drum falls, and the wheel J rides up to the position shown in Fig. 4, at the same time automatically opening the valve F of a sand-container G through the medium of pivoted levers W, W<1>. The pivot R of the lever Q is eccentric with the rear wheel so that, as the wheel J rises, it passes out of effective contact, with the drum K.

Abstract: 1,149,900. Aircraft instruments. KOLLSMAN INSTRUMENT CORP. 4 April, 1966 [30 June, 1965], No. 14936/66. Heading B7W. [Also in Divisions F2 and G1] An aircraft flight instrument comprises a graduated tape 15, 16, 43, 45, 52 movable vertically past a stationary marker 13, 14, 44, 46, 53 to indicate an actual value of an aircraft parameter, (e.g. altitude-tapes 15, 16, pitch, 43, mach number 45, and indicated airspeed 52) and a movable marker 19, 47, 54 set to a desired value (e.g. as shown on counters 22, 49, 57) which moves with the corresponding graduation on the tape, so long as it is visible through the window in the front of the instrument. The desired value may be altered by moving a knob 23, 48, 55 vertically to increase or decrease the value; moving the knob to the right brings the desired value into agreement with the actual value, the necessary circuit, Figs. 12 and 13 (not shown) is described. When the desired value is outside the range of values visible through the window the marker 19, 47, 54 remains at that end of the scale. An intermittent drive for the marker is described in connection with Fig. 14 (not shown, see Division F2). The tapes 16, 43, 45, 52 are wound back and forth between reels 72a, 72b, by sprockets 71a, 71b, and each of these tapes has a tensioning device Fig. 15 (not shown) to allow for the varying diameters of the reels. Tape 15 is continuous and undergoes one cycle for each unit (of 1000 feet of altitude) moved by tape 16. The markers 19, 47, 54 may be carried by tapes 78 for which a tensioning device, Fig. 16 (not shown) is described. Illumination of the tapes is by a lamp 68 (see Division G1). Electrical signals corresponding to the required flight parameters are received from an air data computer. A method of converting these signals into tape movements is described. This conversion process is monitored and in the event of breakdown of the conversion process a flag 20, 50, 59 appears in front of the corresponding tape. The altitude can be corrected by variation in barometric pressure, shown at 28. Vertical air speed is indicated by a pointer 31 moving across a fixed scale 32. When the value is beyond the range on the scale it appears on a moving tape 33 through either window 34 or window 35 at whichever one the pointer 31 indicates.

Abstract: 429,709. Blowpipe apparatus. CAMPBELL, L., 2828, Washington Avenue, Cleveland, Ohio, U.S.A., and BINGHAM & CO., Ltd., C., 34, Victoria Street, London. May 18, 1934, No. 15116. [Class 75 (i)] [See also Group XII] Blowpipe apparatus for removing metal by oxidation by using a stream of oxygen at relatively low velocity and pressure, in which in order to burn for heating purposes a combustible gas having a lower velocity of flame propagation than acetylene, the blowpipe is provided with a shield 5 extending a substantial distance beyond the exit for the gas and surrounding the base of the heating flame to protect and prevent extinction of the flame. The burner described is intended particularly for use with coke oven gas but town gas, hydrogen, petroleum and other gases may be used. A blowpipe tip 1, Fig. 2, for scarfing steel billets and for similar operations is formed with a relatively large central bore 2 for oxygen and a number of parallel smaller-passages 3 for the preheating gas admixed with oxygen. As far as possible the bores are smooth and do not contain constrictions or abrupt changes in cross section. The outer end of the tip is formed with a recess or counterbore 6 forming a shield for the protection of the base of the heating flame. In modified forms the passages 3 may be grouped to one side and the shield need not then include the passage 2. When coke oven gas is used it should be purified. A plant for this purpose, Fig. 3, comprises a water tank 20, and purifiers 21, 22 and 23 which may contain a mixture of iron filings, salt and shavings thoroughly moistened and spread on trays. From the purifiers the gas is forced by a compressor into a storage reservoir 28 and passes through a dehydrator 29 before use. Specification 412,946, [Group XXII], is referred to.

Abstract: 673,559. Propelling ships. CRABALONA. V. June 19, 1950 [June 21, 1949], No. 15280/50. Classes 113 (ii) and 114. [Also in Group XXXI] An endless track for amphibious vehicles comprises a chain each link of which carries a movable blade which can occupy two positions, one for propelling through water or a retracted position, which is assumed automatically by contact of the blades with the ground when the vessel lands, for travelling overland. A guide plate may be provided which ensures that the blades assume the retracted position whilst travelling over the guide and driving drums, and along the upper run between the drums. Figs. 1 and 3 show the vehicle with pedal-operated driving drums 5 for the endless track 1, but the track may be powerdriven. The drive to either track may be declutched by lever 12, to permit sharp turning movements of the vehicle. Water-tight compartments 6 may be provided within the tracks, and the two compartments may be in communication with one another. The track comprises a chain to the links of which are pivoted blades 2, Fig. 6, haying upper projections 8. Fig. 6 shows the position assumed by the blades when travelling in water. As the vehicle approaches land the blades 2 are turned by contact with the land into the position shown in Fig. 7, and the vehicle progresses over land with the blades in the retracted position. The blades are also caused to retract whilst passing round the drums 4, 5 and along the upper run between them by a guide plate 7, which engages the projections 8 as each blade reaches the rear end of its lower run, and which keeps the projections 8 depressed until the blade again reaches the lower run at the front.
