Title: Improvements relating to remote inspection equipment
Inventor: SOAR GEOFFREY KEITH
IPC: G21C17/08
Filed: 1959-02-19
Abstract: 879,529. Television. A.E.I.-J. THOMPSON NUCLEAR ENERGY CO. Ltd. Feb. 1, 1960 [Feb. 19, 1959], No. 5807/59. Class 40(3) [Also in Group XL(a)] A television camera 3 for use in inaccessible locations, such as the fuel channel of a nuclear reactor, is carried on the end of a hollow supporting hose 2, by means of which it may be lowered and raised, means being provided for effecting a forward flow 8 of coolant gas through the hose and television camera and a return flow through an outer path 9 which extends around the camera. In cases in which the coolant requirement is large the return path may extend along an outer path 10 concentric with the forward path 7 of the hose and the coolant may be circulated with the aid of filter 14, cooling device 15 and blower 16. In cases where the coolant requirement is small, the coolant may discharge into the reactor from the top of the camera outer path 9, Fig. 2 (not shown). A limited leakage may also be provided from ports 12 at the underside of the camera in order to cool handling apparatus 11 which may be combined with the camera. In all cases where leakage or discharge occurs into the reactor, the cooling gas is chosen to be the same as that employed in the reactor. The winding drum 1 for cable 2 is located in an auxiliary pressure vessel 4 connected to main chamber 6 of the reactor. Rotating joints 18 are provided on the drum to permit connections to be made from the hose to apparatus 14-16. Additional coolant is supplied at 17 to make up for leakage. A more detailed construction of the camera is described with reference to Fig. 3 (not shown). Specification 879,528 is referred to in connection with combined television and handling equipment.

Title: Improvements in or relating to Gear Wheels.
Inventor: GLEASON JAMES EMMET
IPC: B23F9/10
Filed: 1917-04-25
Abstract: 109,021. Gleason, J. E., and Stewart, A. L. Oct. 6. 1916, [Convention date]. Toothed wheels.-The teeth of spur or bevel gear-wheels are curved from end to end on an arc of a roulette, and are also generated to involute form by a relative rolling of the blank and the cutting-tool. The teeth are cut by a rotary or other tool having teeth x, y to operate on a blank which is continuously rotated. In the arrangement shown, the teeth x cut successive gear teeth, and the teeth y pass through the blank without cutting. The blank is afterwards reset so that the teeth y operate on the opposite sides of the gear teeth. In a modification, pairs of teeth x, y pass through the blank successively, each pair cutting the opposite sides of a tooth or of a tooth space Instead of being oblique as shown, the gear teeth may be arranged so that their chords lie in radial planes.

Title: A device for measuring ground speeds or distances in connection with aircraft
IPC: G01C22/00
Filed: 1937-02-27
Abstract: 489,514. Speedometers; odometers ; accelerometers. DOWTY, G. H. Feb. 27, 1937, No. 5982. [Class 106 (iii)] A device showing distance and/or maximum speed of run upon the ground of an aircraft is driven by a landing wheel of the aircraft through clutching means engageable by the deflection of a ground-loaded part of the aircraft. An acceleration recorder may be incorporated with the device for testing brake efficiency. In the construction shown in Fig. 1, the undercarriage of the aircraft incorporates a telescopic shock-absorber strut 1, 2, the part 2 having pivoted on it a spring controlled lever 5 to which is pivoted the rod 7 having a stop 7a moving under the control of a spring 10 in a tube 8 pivoted to the part 1. The lever 5 carries the device 11 showing distance and/or maximum speed and driven by a wheel 12 from the aircraft wheel 4 either frictionally in which case the wheel 4 is provided with an annular track or by teeth on the wheel 12 engaging a ring of teeth on the wheel 4. The wheel 12 mav be made of solid rubber or fibre or may be provided with a rubber tyre. When the aircraft becomes air-borne relative movement between the parts 1 and 2 causes rotation of the lever 5 and disengagement of wheels 4 and 12. In the construction shown in Fig. 3, the pinion 24D is rigid with a shaft secured to the hub cap of the wheel 24 and engages with a pinion 26 driving the distance and /or maximum speed indicating device 28 through the flexible cable 27. The pinion 26 is mounted on a lever 25 pivoted on one part 22 of a telescopic shock-absorber strut 21, 22, the lever being connected to the part 21 through the telescopic compression link 29, 30, 31 and collar 32 which is adjustable on the part 21 so that the pinions 26 and 24D engage at a predeterminedminimum ground load of the aircraft. The pinions 24D and 26 can be disengaged by pulling on the cable 33 connected to the lever 25. Movement between the parts 21 and 22 due to rough ground is allowed for by the spring 31. The indicating device, Fig. 4, comprises a speed driven disc 44 having a pin 43 for rotating a pointer 41, frictionally mounted on the spindle 42 to give maximum readings, and a distance register 45 zeroized by a knob 46.

Abstract: 900,741. Drawing. ANACONDA AMERICAN BRASS CO. Feb. 20, 1961 [April 22, 1960], No. 6142/61. Class 83 (4). A tube pointing apparatus comprises a frame, a stationary die fixed to the frame, and first and second movable dies displaceable relative to the stationary die, said dies when in the open position together defining an opening sufficiently large to receive the tube, and when closed defining a cavity of polygonal cross-section of less width than the maximum width of the tube, said stationary die defining at least two adjacent sides of said cavity and said first and second movable dies defining the remaining sides of said cavity. The frame 10 has a vertical surface 11 and a horizontal surface 12 which between them support the two sections 16 and 17 of the stationary die. The part 16 has a V-shaped groove 19 therein which forms two sides of an hexagonal cavity, and the flat upper surface of the block 17 forms a third side of the cavity. A plunger 13 operated by an hydraulic or pneumatic cylinder carries a first movable die 23 which slides against the surface 20 of the block 16 and has a flat working surface 25 which forms one side of the cavity. Mounted on a power-operated plunger 14 is a second movable die 27 which has a base portion 28 and a projecting portion 29 which slides between the block 17 and the die face 25 when the first die is closed. The end of the portion 29 has a V-groove which forms the two remaining sides of the hexagonal cavity which exists when the dies are in the closed position. In operation, a tube is placed between the open dies as in Fig. 1, the first die 23 is brought down until the surface 25 is level with the top edge of the groove 19, thus forming the tube to an oblong cross-section with rounded ends and then the second die 29 is moved in until the tube is compacted as in Fig. 3. In a modification, the cavity is octagonal, Fig. 5 (not shown), and two sides of the cavity are formed in each of the stationary die parts and in each of the moving dies.
