Title: Nuclear reactor power installations
IPC: G21D5/06
Filed: 1973-05-24
Abstract: 1443700 Nuclear power plant NUCLEAR POWER CO (WHETSTONE) Ltd 24 Aug 1973 [24 Aug 1972 24 May 1973] 39409/72 and 24821/73 Heading G6C In nuclear power plant including a main boiler 11 and an auxiliary boiler 12, steam-to-steam reheat is provided between two successive stages 24B, 24C of the main turbine 24 in a reheater 19 supplied with a portion of the steam generated in the auxiliary boiler 12. In the embodiment shown, in which the boilers are disposed in pods in the wall of the pressure-vessel 10 of a helium-cooled HTR, steam from the auxiliary boiler 12 drives a turbine 13A coupled to a main coolant circulator 13 and, after leaving the turbine, is apportioned between low-pressure turbines 15-17 and the reheater 19. Steam exhausting from the turbines 15-17 is fed, via line 27, to the main turbine steam run either upstream of the reheater 19 (as shown) or downstream thereof. In a modification (Fig. 2, not shown) the circulator 13 is electrically driven enabling the associated steam turbine to be dispensed with. A stand-by fossil-fuelled boiler may supply steam to the circuit of the auxiliary boiler in appropriate circumstances to enable continuity of electric power generation by a generator 18 (Fig. 1) or generators (18, 30) (Fig. 2, not shown), such power being required for use in the plant. The auxiliary boiler 12 is of the once-through type. In a further embodiment (Fig. 3, not shown) the auxiliary boiler 12 is of the recirculation type but consists solely of an evaporator section. The mixture of water and saturated steam generated in this section passes to a steam drum (12A) into which make-up feed-water is fed directly. A pump (12C) returns water from the steam drum to the boiler.

Title: Machine for casting or moulding bodies from thermoplastic pulverous material
IPC: B29C45/03
Filed: 1930-08-20
Abstract: 350,810. Casting bobbins &c. in moulds charged through pressure nozzles. BUCHHOLZ, H., 32, Berlinerstrasse, Neuk÷lln, Berlin. Aug. 20, 1930, No. 24890. [Class 87 (ii).] In presses for handling thermoplastic material in which the material is heated in a press cylinder and then forced by a ram through a charging nozzle into a mould formed in two halves held in close abutment, the ram moves downwards in the cylinder until the material wedges, after which the ram and cylinder move as a unit to apply pressure to the upper mould section during the moulding operation, thereby maintaining the mould parts in close relationship without special locking means. The press cylinder 21 carries the nozzle 29 which fits into the water-cooled upper section 31 of the mould and is provided with an electric or other heater 26 at its central portion. The cylinder 21 and mould member 31 are connected to a metal beam 14 which can be raised by chains 16 and a pedal to separate the mould parts against the action of springs 19 which apply initial compression to the mould members. The ram 6 is lowered by the counterweighted handle 10 acting through rack- and-pinion gear to force material from the hopper 24 into the press cylinder 21. When the material jams, the continued movement of the handle moves the member 14 downwards and thus forces the shoulder on the nozzle 29 and the abutment members 63 against the mould member 31. The cooling fin 27 and metal beam 14 prevent the heat from softening the material in the hopper. In the particular machine illustrated, which is for the manufacture of small bobbins, the mould member 31 depresses cores 43 bodily against the action of springs 49. When the member 31 is raised again, the springs raise the core members clear of the lower mould members, in which position the moulded articles are ejected from them by a sliding bar 52 operated by a cam 60 rotated by th e hand-lever 59.

Title: A process for the protection of carbon electrodes for electric furnaces
IPC: C25C3/12
Filed: 1957-08-07
Abstract: Electric furnace carbon electrodes, especially pre-baked or self-baking electrodes used in the electrolytic production of aluminium, are produced by mixing a boron compound free from iron with the carbon-containing raw materials of the electrode so that it is evenly distributed therein.  Boric acid, alkali metal borate, ammonium borate, or an organic boron compound, e.g. methyl borate are added in a proportion of 0.2 to 1 or up to 3% based on the weight of the electrode mass.  The boron compound is added to the calcined raw materials comprising graphite, anthracite, petroleum coke, pitch coke, or cinders either before or after crushing and screening or during the heating of the materials to 100-170 DEG  C.  The binding agent, e.g. coal tar pitch, is added in a proportion of 20-30% and the mixing is continued. The boron compound prevents burning of the electrode and reacts with the small proportions of metal or metal compounds, especially vanadium oxide, probably forming vanadium boride.  When applied to an aluminium furnace, the vanadium content of the aluminium is reduced from 0.025 to 0.005%.

Title: Improvements in or relating to tire building machines
IPC: B29D30/24
Filed: 1950-10-12
Abstract: 683,785. Tyre-building machines. NATIONAL STANDARD CO. Oct. 12, 1950 [Oct. 28, 1949], No. 24933/50. Class 144 (i). A tyre-building machine comprises a main drum 45 and an auxiliary drum 46 at the side, the carcase fabric being applied to the main drum 45 and extending to the desired degree over the edge of the auxiliary drum 46 which is provided on its surface with an inflatable bag and there being a cage-like cylinder 220 disposed so as to be movable axially first to lie around the auxiliary drum 46 and later being movable into position around the main drum 45 but only after the bag has been inflated to the required pressure and has expanded into contact with the cage-like cylinder to grip the extending edge of the carcase fabric, the axial movement then folding the extending edge of the fabric around on to the top of the fabric on the main drum, for instance around bead rings which were previously placed in position and moved up to shoulders formed by slightly radially expanding the main drum. The motion of the cage is controlled by limit switches and the movement of the cage away from the main drum 45 cannot start until the bag has been deflated and has by its elasticity sprung back axially into its normal position on the auxiliary drum 46. Thus a tyre-building machine may comprise a main collapsable drum 45 mounted between an auxiliary drum 47, carried by a tail-stock 10 adapted to be swung into and out of alignment and to be axially moved toward and away from the main drum, and a second auxiliary drum 46 carried-with the main drum-on a fixed stanchion 1. Mounted on each of the auxiliary drums is an inflatable air-bag having a normal external diameter corresponding to that of the collapsed main drum on which the fabric is initially laid with its edges extending on to the air-bags. After a small radial manuallyeffected expansion on the main drum to provide shoulders for the beads and assembly of the beads, the drum is fully expanded to tighten the fabric around the beads. The cage 220 having an internal diameter substantially greater than the drum-assembly diameter is now moved, from the inoperative starting position, as shown, over the adjacent auxiliary drum, the air-bag on which is then inflated to force the fabric lying thereon into firm contact with the cage. The latter is then moved into position over the main drum on to which the fabric trapped in the cage is progressively folded. The operative air-bag is then deflated and collapses on to its drum element; the cage then advances to lie over the tail-stock auxiliary drum 47 in readiness for corresponding manipulation of the fabric edge extending on to the other auxiliary drum, and is finally returned to its starting position. The step-by-step movements of the cage and the pressure-changes in the air-bags during the cycle are electrically controlled by limit switches 241A ... 241E operated by a plate 240 on the chain-driven carrier of the cage and by tiltable mercury switches operated by the air pressure in the bags.
