Title: Improvements relating to aircraft undercarriages
IPC: B64C25/50
Filed: 1937-10-22
Abstract: 509,923. Aircraft alighting-gear. MACLAREN, 0. F. Oct. 22, 1937, Nos. 28901/37 and 11893/38. [Class 4] An aircraft comprises means for facilitating cross-wind alighting and take-off, which means includes mechanism whereby main and subsidiary landing elements may be directionally set by an occupant of the aircraft, the subsidiary element being directionally movable such that the aircraft may be steered without accompanying change of setting of the main elements. In one form, landing-wheels 14 are disposed rearwardly of the centre of gravity of the aircraft and a nose landing-wheel 15 is disposed forwardly of the centre of gravity. The wheels 14 are carried by telescopic shockabsorbing struts, relative rotation between the parts of which is prevented. Each shockabsorber is mounted on bearings and carries an arm 17 having a slot 20 which engages a nut 28 translatable on rotation of a shaft 32 from a hand wheel 34. The hand wheel 34 is mounted on a shaft 33 which, through a nut, lever 19, link 18 and an arm 17A adjusts a nose wheel 15. The fulcrum 21 of the lever 19 is mounted in a slide and connected to the rudderbar 25. The wheel 15 may be mounted in a fork 43 carried by a tube 44 telescopically arranged with relation to a tube 39 mounted in and brased to the aircraft. The lever 17A is connected to a cam member 51 which cooperates with a cam member 48 and a spring 50, disposed in the tube 44, to restrain castoring. Provision for castoring may be made by making the link 18 telescopically yieldable. In a modification, operation of a hand wheel 67 through a worm 66, a quadrant 65 and a piston 61 displaces fluid from a cylinder 60 to a cylinder 59 to displace a piston 58 against the pressure of air in a space 69 which communicates with a compressed air bottle 70. The fluid moves the piston 58 to move the wheel 14 through a quadrant 54. A common hand wheel operates all the wheels and valves 72 having rods 73 are provided in the pistons 61 and factilitate tapping up and synchronizing the wheel portions. The quadrant 54 may co-operate I with a hydraulically-operated lock. A rod 86 i is connected to a piston 65 whereby the piston I may be moved against the action of a spring I 80 to displace fluid from a cylinder 76 to i cylinders 77 in which pistons 78 connected to the locking plungers 79 are movable against the action of springs 81. Spring-urged detents 87 are adapted to engage recesses in the pistonrods of the pistons 78 to hold the plungers 79 inoperative. The control mechanism for setting the landing elements are associated with a I, visual drift indicator. The pilot sets the crosswires 91 of the indicator in the direction of travel over the ground by rotating a verge ring ` 92. The wheels are then adjusted until wheel I indicators 96 connected to the wheels are in parallelism with the wires. The shafts 32, 33 may be flexible and the undercarriage may be retractable.

Abstract: 377,042. Printing - machines. ADREMA MASCHINENBAUGES., 62, Alt- Moabit, Berlin. Oct. 27, 1931, No. 29821. Convention date, Oct. 27, 1930. [Class 100 (ii).] Addressing-machines; tripping-arrangements. -In a hand-operated addressing-machine of the kind comprising a rocking platen arm and in which a locking-device is provided to interrupt the address-plate feed for repeat printing, the locking-device is held in the operative position by a spring and is released by rod mechanism actuated from a point adjacent the handle of the platen arm. A skipping-device may be provided also. As shown, the addressplates are fed through the machine by a reciprocating slide moved forward at each up stroke of a platen arm 3 by means of a rod 19, which engages a recess in the lower end 31 of the arm 3 and is connected to a pivoted arm linked to the slide. A spring attached to the pivoted arm tends to retract the slide during the down stroke, but this is prevented, in one form, by a lever 58, Fig. 4, the end 59 of which normally lies in the path of an extension of the link connected to the slide. The lever 58 is pivoted at 60 and is moved into the operative position by a spring 62. When the required number of impressions has been printed from the plate in printing position, a knob adjacent to a handle on the arm 3 is pressed and, through a pivoted lever and a rod 48, rocks a gear segment 47 to the left so as to rotate a pinion 46 carrying a crank 55 adapted to raise a slidable bar 56 which, during the next down stroke, rocks the lever 58 into an inoperative position. The gear 46 is fixed to a flat-sided pin 44 which turns into a position where it prevents the full descent of the arm 3 as described in Specification 376,120 ; a further impression is therefore avoided. The lever 58 may be moved into an inoperative position by turning a cam-lever 66 so that the machine may be used for consecutive printing, and the skipping-device may be put out of action by turning into an inoperative position a plate 67 normally forming an abutment for the pin 44. In a modification, the rod 19 is detained in repeat-printing position by a pivoted plate 23, Fig. 12, spring-pressed into engagement with a groove in the rod. By pushing a rod inwardly as before, a cam 29 is rotated and rocks the plate 23 so as to release the rod 19. A skipping-device 34 of known type is simultaneously moved into the vertical position to prevent the full descent of the arm 3.

Abstract: 1,196,730. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 13 June, 1969 [2 July, 1968], No. 30141/69. Heading G6C. A clamping arrangement for a nuclear reactor core containing a plurality of fuel bundles comprises retainer band means surrounding the fuel bundles, being spaced from them when the reactor temperature is below the normal operating temperature, the thermal coefficient of expansion of the band means being less than that of the easing material of the fuel bundles so that the latter come into contact with and are clamped together by the band means as the reactor temperature approaches the normal operating temperature. The band means comprises a band 26 along the inside of which are welded a number of segmented filler plates 28 having honeycomb inner edges to match the circumferential shape of the assembly of fuel bundles 12. During the initial assembly period or when reactor operation is reduced for refuelling, the reactor temperature is at a relatively low temperature (e.g. 300-375‹ F.) and the filler plates 28 are not in contact with any of the fuel bundles 12 which are thus in a generally loose condition, making it convenient to remove and replace any selected fuel bundle. As the reactor approaches normal operating conditions and the temperature increases substantially (as e.g. up to 900-1100‹ F.), less thermal expansion takes place in band 26 than within the fuel bundle assembly so that the filler plates 28 come into contact with the outer row of fuel bundles 12, with the result that the fuel bundles 12 are locked firmly in place against vibration and bowing during normal operation. The outer casings 25 of the fuel bundles 12 may be of stainless steel and the band 26 and filler plates 28 of a suitable vanadium or titanium alloy. The band 26 may extend as a sleeve for the full length of the core.
