Title: Vertical vacuum die casting machine
IPC: B22D17/14
Filed: 1965-10-07
Abstract: 1,058,439. Casting machines. G. R. MORTON. Oct. 7, 1965, No. 42698/65. Heading B3F. A vertical vacuum diecasting machine comprising a vertically movable upper die half (37) (Fig. 1, not shown) and stationary lower die half (41) which together define the mould cavity (38), having also ejector pins (23) which operate in bores (36) which pass through the upper die half, is provided with vacuum means for evacuating both the mould cavity and also the upper ends of the ejector pin bores. A shot cylinder (48) with its plunger (81) extends through the lower die half (41) and a bottom platen (10) and communicates at its upper end via gate (52) with the mould cavity (38) and at its lower end via tube (115) with a bath (111) of molten metal. An annular vacuum groove (55) in the upper die half (37) surrounds the mould cavity (38) and communicates therewith by a short passage (56). This passage is adapted to be sealed off by a shut-off pin (57) which passes through the upper die half. An annular vacuum groove (72) in an ejector box support plate (19) closely surrounds the ejector pin bores (36) and in operation evacuates any air tending to leak down these bores. A vacuum passage (73) leading from the groove (72) evacuates air tending to leak past the shutoff pin (57). In operation the application of vacuum to groove (55) draws molten metal into the shot cylinder (48) from which it is forced into the cavity (38) by plunger (81). Shut-off pin (57) is lowered at the appropriate point in the cycle to seal the passage (56) and thereby prevent metal entering the passage (55). When the die halves are separated by a main ram (13) plunger (81) lifts the finished casting for a short distance from the lower die half (41) and as the upper die half (37) continues to move upwardly ejector pins (23) press the casting from the upper die half under the action of an auxiliary ram (27). When the plunger (81) is in its lowest position vacuum is applied to a groove (103) in the shot cylinder wall to prevent leakage of air into the cylinder and to draw lubricant from a groove (100) into the cylinder. Application of vacuum to the shut-off pin bore is similarly used to draw lubricant into the bore from a line (76). Coolant is supplied to the interior of the shot plunger (81), to annular passages (130, 135) around the shot cylinder and to a circular depression (141) in the upper die half.

IPC: G21C1/08
Filed: 1962-11-19
Abstract: 1,032,396. Reactors. SOC ANGLO-BELGE VULCAIN S.A. Nov. 13, 1963 [Nov. 19, 1962], No. 43616/62. Heading G6C. A liquid moderated nuclear reactor has a core formed of elongate fuel rod assemblies between which are spaces which accommodate hollow slab-shaped control members. The moderator, which also acts as coolant, is preferably pressurized water, and the hollow control members are open at both ends so as to enclose a volume of moderator when inserted in the core. The reactor described is suitable for marine use, and comprises a core of fuel assemblies 2a, each formed of a number of parallel fuel rods, supported on a bottom plate 3 suspended by a lower tubular member 5 which is attached to an upper tubular member 8 attached to the wall 1 of the pressure vessel. Water enters through a port 13 and passes downwards on both sides of the lower tubular member 5, and upwards through the core, via passages 19, 20. The core is surrounded by a zircalloy lining 17 (see also Fig. 2) held in position at its base by engaging a correspondingly shaped hole in a plate 3a, and at its upper end by an identically shaped flange 18. The lining 17 is freely supported so as to move radially and axially. The fuel element assemblies are suspended from tubular extensions 26 by means of an extension rod 22 and an abutment plate 24. The plate 24 is resiliently urged downwards on to an abutment plate fixed to the extension tube 26. The core section (Fig. 2) includes fixed guide surfaces integral with the bottom core plate, namely, the lining 17 and lattice plates 27. The lattice plates are in the form of parallel shallow troughs so that two such members joined face to face define a series of narrow channels; these channels accommodate hollow control rod members 28. The spaces between the control member channels are cross subdivided by plates 27b to form a number of channels, each of which contains a fuel element assembly. In a first modification (Fig. 4, not shown), the fuel element assemblies are of right triangular cross-section and are placed in pairs to form squares of which the control member channel is a diagonal. A second modification (Fig. 5, not shown), is very similar to that shown in Fig. 2, except that each control member channel is of unitary construction.

Filed: 1972-09-21
Abstract: 1412452 Magnetic amplifiers WESTING- HOUSE BRAKE & SIGNAL CO Ltd 12 Sept 1973 [21 Sept 1792] 43743/73 Heading H3X A magnetic amplifier, Fig. 2, has a fail-safe output nullifying property in the event of an A.C. excitation winding becoming short-circuited, the amplifier comprising three flux paths formed by cores 1, 2, 11 with A.C. excitation windings 3 and 4 coupling cores 1, 11 and 2, 11, respectively. A D.C. control winding 6 common to cores 1 and 2 is magnetically decoupled from the two excitation windings, and an A.C. output is obtained from a winding 12 on core 11. A short-circuited turn 10 coupling cores 1 and 2 is preferably provided. In operation, if either A.C. excitation winding becomes short-circuited the presence of this short circuit coupling cores 1 and 11, together with the shortcircuited turn 10 coupling cores 1 and 2, causes the alternating flux in core 1 to be coupled into core 11 in such a direction as to oppose the alternating flux induced by the operative A.C. excitation winding. If the short-circuited winding 10 is omitted, the same functioning is obtained provided the control winding is connected to a low impedance source or is shunted by a capacitor, Fig. 9 (not shown). In an application to a dynamic brake monitoring circuit for the electropneumatic braking system of a train, the brake current is applied to the control circuit 21 of a magnetic amplifier 22, Fig. 6, and the amplifier output after rectification at 23 is passed through the coil 24 of an electropneumatic brake converter. A rate feedback signal is also obtained from the magnetic amplifier output circuit by the combination of a transformer 25, rectifier 26 and differentiating capacitor 28. The rate signal so obtained is applied through a transistor 30, a non-linear load formed by a chain of diodes 31-34, and a transistor 36, the signal being then amplified by a magnetic amplifier 35 incorporating the fail safe arrangement of Fig. 2. After rectification at 37 the amplified rate signal is combined with the direct feedback signal in the coil 24. The amplifier 35 may have additional control windings. Fig. 8 (not shown), for applying a brake command signal and a signal indicative of a degree of electric braking being produced.
