Abstract: 708,966. Skips with bottom discharge. SLATER, A. Nov. 20, 1951 [Dec. 12,1950], No. 27177/51. Class 78 (4) The side and bottom walls of a basket for unloading fish and other cargo are of net and the bottom wall 11 (Fig. 2) has a discharge opening 26 which may be closed by a draw rope 25. The ends of the rope 25 are formed with pineapples 23a, 24a by which they may be secured in slots 22 in the ends of one of a pair of spreaders 13, 14 secured to the upper edges 5a, 5a (Fig. 1) of the basket to hold the opening 26 closed. The walls of the basket are defined by upper and lower rope frames 5, 6, joined by side ropes 7. The net panels are seized to the ropes 5, 6, 7 by cords 12 which also secure the wooden spreaders 13, 14 to the upper sides 5a, 5a of the basket. The basket may be suspended for hoisting by a pair of ropes 17 each secured to brackets 16 on one of the spreaders 13, 14 and threaded through a ring 19 adapted to slip over a crane hook 20. It may be suspended for filling by rope bights 33 (Figs. 1 and 4) secured at 31 to the walls 32 of a hold and slipped over the ends of the spreaders 13, 14. Hinged flaps 35 on the walls 32 may then rest on the spreaders to guide fish into the basket. The pineapples 23a, 24a and the ends of the spreader 14 may be coloured to indicate the proper anchoring of the ends of the draw rope 25. The ends of the draw rope 25 may be provided, beyond the pineapples 23a, 24a with eyelets to facilitate manual handling. Canvas strips arranged radially in the bottom of the basket may facilitate the movement of small fish to the discharge opening. The basket may be cylindrical and its shape may then be defined by upper and lower metal rings to which the netting walls are secured.

Abstract: 866,710. Securing turbine and compressor rotors on shafts. BIRMINGHAM SMALL ARMS CO. Ltd. Aug. 30, 1957 [Sept. 6, 1956], No. 27264/56. Class 80 (2). [Also in Groups XXV and XXVI] The turbine rotor 1 and the compressor rotor 2 of an elastic fluid turbine are connected by Hirth couplings 8, 10 to a hollow shaft 3, a tiebolt 6 screwed into a tapped hole 4 in the turbine rotor and having a lock-nut 18 at its far end holding the parts together. When connecting the parts, the tie bolt 6 is first screwed into the turbine rotor 1, and the hollow shaft 3 is then slipped over the tie bolt. Radially inwardly projecting teeth 14 at the end of the hollow shaft 3 slide between axial splines 13 on an enlarged portion of the tie bolt, and facial teeth 8 of the Hirth coupling at the end of the shaft then interdigitate with similar facial teeth 9 on the hub of the turbine rotor. The tie bolt 6 is thereby locked in the turbine rotor 1. The Hirth couplings comprise axial teeth 8, 9, Fig. 2, tapered radially inwardly and axially, the dimensions of the teeth being such that the tips of the teeth 8 are spaced from the roots of the teeth 9, and vice versa, when the couplings are assembled, to reduce transfer of heat between the parts.

The pole pieces are arranged staggered in the stator casing so that the magnetic field between the pole pieces is mainly perpendicular to the chord of the rotor blades, which are non-magnetic e.g. of aluminium alloy or austenitic steel Several de- @cers may be spaced equally in the circumference of the stator and also axially of the stator, e.g. one bridging the guide and first stator ring and another bridging the first and second stator vane rings. The pole pieces have flat opposite faces in parallel planes set athwart the general plane containing the pole pieces and have rounded edges 25 so that they replace vanes when inserted in the stator. D.C. or A.C. e.g. at 400 cycles per second is used. Reference has been directed by the Comptroller to Specification 625,299.

Abstract: 1474074 Continuous casting CONCAST AG 21 June 1974 [22 June 1973] 27775/74 Heading B3F [Also in Division F4] A thin fan of a mixture of molten steel and inert gas, such as Ar, pours from tube 3 into a mould and extends downwardly into the pool of steel in the mould and towards opposite sides of the mould, the gas having been bubbled into the steel, e.g. through a pipe 21, if the pouring rate is controlled by a sliding gate, or through a hollow stopper rod (11) of a tundish to which the pouring tube 3 is secured. The depth of penetration of the fan jet is determined by the rate at which the gas is added and this rate is between 1 and 6 litres/tonne. The flotation of impurities up to the slag layer is said to be improved because downflow at the narrow walls of a slab mould is reduced. In the case of an arcuate mould, as shown, with curved wide walls 8, the jet is angled towards the inner wall, either by having a tube 3 with a slanted outlet slit 15 or by tilting a tube with an axial slit, at 4-6 degrees to the vertical. Such arrangements may also be used in a straight-cavitied mould in a plant with an arcuate guide apron. The slit 15 is 6-30mm wide.

Pumping-machines; starting, facilitating.-The arrangement described in the parent Specification for starting a centrifugal pump and cooling a water ring pump is modified by the interposition of an auxiliary tank 10 in the bye-pass between the two pumps, and the bye-pass is only opened when the liquid in the tank reaches a predetermined level. The water ring pump 2 may be on the same shaft as the centrifugal pump 1. The suction and discharge ports of the pump 2 communicate with the tank 10, and the suction pipe 4 of the centrifugal pump 2 is also in communication with the tank 10 by a pipe 7 closed at its lower end by a valve 8 which can be opened by a float 11. At starting, the pump 2 draws air from the suction side of the centrifugal pump and discharges it through the pipe 5 into the liquid in the tank 10 from which it escapes by the pipe 6. After the suction pipe 4 has been freed from air the pump 2 discharges water and the level in the tank 10 rises. The float 11 then opens the valve 8 so that water circulates from the pipe 4 through the pump 2, pipe 5, tank 10 and pipe 7. If the level falls, the valve 8 closes and the cycle of operations is repeated. The arrangements may be used with benzine and similar liquids.
