Title: Two-speed hub gear and coaster brake
IPC: E03D5/09
Filed: 1960-04-11
Abstract: 872,353. Change-speed gear. BENDIX CORPORATION. April 11, 1960 [April 30, 1959], No. 12845/60. Class 80 (2). [Also in Groups XXXI and XXXIV] A semi-automatic two-speed hub and coaster brake, (Group XXXI), for cycles has mechanism which transfers the drive from a chain sprocket wheel 26 either direct to a high-speed screw shaft 19 carrying a high-speed clutch nut 22 or through a sun-and-planet reduction gear 25, 29, 31 to a low-speed screw shaft 16 carrying a low-speed clutch nut 17 and coaxial with the shaft 19 previously mentioned. By means of continuous frictional connection by a spring tongue at 51 between the hub 9 and the lowspeed nut 17 and at 53 by a friction ring between the low-speed and high-speed nuts, rotation of the hub 9 when coasting causes rotation of the low-speed clutch nuts by drag whereby one or other nut is disengaged from its respective drive seating inside the hub and the other is engaged instead, thereby changing gear. Engagement of the nut 22 is prevented at low gear by projecting spring arms 41 on a sleeve 39 on the nut itself. These arms bear frictionally on the outside of a ring 37 journalled outside a thimble 43 fixed on to the fixed axle 1 and can engage with their ends lugs 38 on the ring to prevent rotation, the ring being held fast by spring pawls 46 on the thimble 43. Axial motion of the nut brings slots 42 into line with the lugs 38 and allows the nut 22 to rotate when changing from low to high gear.

Abstract: 1,245,974. Bale sledges. J. R. CLARK. 17 June, 1969 [16 March, 1968], No. 12865/68. Heading B5F. An open bottomed bale sledge includes a pair of side guiding members 8 defining a bale receiving zone 9 which converges so as to enable bales 78, 79, 80 to pass therethrough in end-toend succession, further side guiding members 13, 14 defining at least two longitudinally extending side-by-side passageways 15, 16, combined gate and deflector means 21 to control entry of bales alternatively into the passageways, means for lifting a block of two or more bales arranged side-by-side in the delivery region 20 to permit a like number of bales to be slid underneath the raised bales, and a tail gate 32 at the trailing end of the sledge, through which a stack of at least two tiers of bales can be released to remain stationary on the ground. The combined gate and deflector means 21 is operated by trip means 30 actuated by a bale so that the following bale is diverted to the other or the next passageway. The trip means 30 is connected to the deflector means 21 through pivoted linkage 25, 26, 27. The bale lifting means comprises gripping members 69, 70 attached to arms 53, 54 which are pivoted on beams (55), 56. The gripping members are moved to bale gripping position by a ram 73 against the action of springs 75, 76. The beams (55), 56 and therefore the gripping means can be raised against the action of springs 67, 68 by rams 59, 60. The tail gate 32 is pivoted at 37, 38 and is self-closing under its own weight. It is held closed by a latch 39 which can be released by the operator. Alternatively, trip members may be provided for automatic control of the rams 73, 59, 60 and the gate 32. Fig. 9 (not shown), shows alternative bale deflector gate mechanism in which the gate 21 is urged into either of two operative positions by over-centre spring means.

Abstract: 1,114,807. Ball mills. SOCIETE NATIONALE DES PETROLES D'AQUITAINE. 23 March, 1966 [23 March, 1965], No. 1289/66. Headilng B2A. Apparatus 2, Fig. I, for grinding, e.g. rock samples into grains of similar size, comprises an oscillatable grinding chamber 3 containing one or more beater balls 5 or like members, a sieve 11, a collecting chamber 13, and a source of compressed air connected to an enclosure of the grinder. A selecting chamber 7 is connected to the grinding chamber by input and output or return passages 8, 9 and a duct 10, Fig. 2, is connected to the source of compressed air opening out into the input passage. The sieve 11 separates the selecting chamber 7 from the collecting chamber 13, which is provided with an air-permeable filter 16, and a recuperator-homogenizer 17 is removably mounted on the grinder communicating with a non-return member 18 preventing any return of the material in the homogenizer to the collecting chamber. As described, the collecting chamber may be divided into parts 12, 13 by a diaphragm 14 provided with a hole 15, which prevents lumpy pieces detached from the filter 16 being projected towards the sieve 11. In operation, the powder which falls into the recuperator 17 is violently shaken by the movement of the whole apparatus and is then homogenized. Moving members e.g. discs (not shown), having stiff flexible wires vibrate in the chambers to keep the apparatus from clogging in the selecting chambers 7, the precollecting chamber 12, where provided, and the collecting chamber 13.

Title: Improvements relating to nuclear reactors

IPC: G21C15/247
Filed: 1963-04-01
Abstract: 1,075,117. Cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 25, 1964 [April 1, 1963] No. 12911/ 63. Heading G6C. In a highly rated nuclear reactor core, e.g. in a fast reactor, a liquid metal coolant is circulated by several pumps in parallel. Reverse flow of coolant through a faulty pump is restrained instantaneously by a counterflow brake which is supplemented by a remotely controlled valve which opens automatically to permit natural convection when complete failure of circulation occurs. The counterflow brake-is a horizontal spiral vortex having an inlet of cruciform cross-section. The valve. is adjustable by a vertical shaft extending through the upper shield plug and by a piston subject to coolant pressure from the pump delivery. Failure of the pump removes the upward pressure thrust on the valve which falls into the fully open position and leaves the coolant path open to permit thermal circulation of the coolant through the core.

[Also in Division B8] The transverse grate bars of a travelling grate are carried by ash pans secured to spaced endless chains and moving with them. The chains 6 are guided by rollers 9 engaging I-beams 10 forming part of the grate frame, Fig. 3, joined at the ends by curved I-section members. Each ash pan 7, Figs. 5 and 8, has a flat bottom 24 with lugs 47 at each side to engage the chains, a front ash retaining lip 25, a front transom 34 spaced above the ash lip and extending upwards to the level of the grate bars 41 supported by the side walls 28 of the pan and a rear wall 31 with a curved part 27 merging into a rearward extension 30 of the bottom plate. The links 49 of the chain are held together by spindles 64 with bosses 15 to engage the driving sprockets at their inner ends and guide rollers 9 at their outer ends. The lugs 47 on the ash pans 7 are held in slots 48 in the chain links by keys 50 with shanks 54 engaging a shoulder on the grate bars 41 so that the ash pans cannot be removed with the grate bars in place. The bars 41 are spaced to give air passages and held by rods 42 welded to them. Projections 45 on the rear ash pan wall and on the front fire bar engage recesses in the rear bar and the ash pan transom, and the grate bars have sufficient resilience to be readily disengaged. As the pans 7 move over the end driving sprocket, ash from one pan falls over the lip 25 to the curved part 27 of the rear wall of the preceding pan, whence it falls as the pan is inverted. The front transom 34 of each pan overlaps the rear wall of the preceding pan, and the lip 25 and bottom tail 30 of adjacent pans form a passage for air. The sides of the grate are sealed by the upper flanges 69 of the guide rails 10, overlapping lips 68 on the chain links and plates 70 secured to the guide rails. The front transoms 34 and upper parts of the rear walls 31 extend over the guide rails 10, as do the grate bars 41, so that two or more grates may be used side by side in a single furnace. The space between the upper and lower runs forms air boxes, divided by transverse partitions, and having individual dumpered air inlets. The sealing members 87 above the air box partitions engage the underside of the ash pans to minimize air flow between the boxes.
