Title: Improvements in methods and machines for making foundry moulds
IPC: B22C15/10
Filed: 1951-12-20
Abstract: 706,521. Moulding-machines. ETABLISSEMENTS A. MARILLIER. Dec. 20, 1951 [Dec. 23, 1950], No. 29920/51. Class 83 (1) A moulding machine for jarring and pressing the mould has means for imparting one or more intensive shocks to the mould at low frequency and a high speed fluid-operated hammer for vibrating the mould table during pressing. The table is rigid with a piston, and a second piston below the first in the same cylinder leaves a space in which fluid can be forced for the intensive shocks. When fluid is admitted below the lower piston both rise for pressing the mould against a head, at the same time pressure fluid reciprocates a hammer longitudinally in aligned bores in the pistons to impart the high frequency vibrations. The mould table 3 is rigid with a piston 14, a flange 16 of the piston normally resting on the closure 51 of the cylinder 2 in which the piston can move. A second piston 15 normally spaced from the first rests through springs 30 on the bottom 19 of the cylinder 2. If air or other fluid is admitted by a handcontrolled valve to the space 17, the piston 14 is moved up until holes 21 in the cylinder 2 are exposed, the pressure in the space 17 is released and the table falls and is jarred by the flange 16 striking the closure 51, this being a low frequency shock. The hammer 22, which slides in bores 53, 23 in the pistons 14, 15 is prevented from rising with the piston 14 by balls 24 which are moved into the position shown in Fig. 3 by air from the space 17 via a passage 25. Alternatively the hammer 22 may have an enlarged end 28, Fig. 5, so that the air pressure passes down the gap 29 and acts on the upper face of this enlargement to hold the hammer down. When the jarred mould is to be pressed against a head which may be swung into position over it, air is admitted at 35 to raise the piston 15, Fig. 6, and then the piston 14 and table 3. Some air also passes along passages 34, 31, 36, 37, 38, 39, 40 into the space 41 thus raising the hammer 22 in the pistons 14, 15. When the hammer strikes the table 3 the air at 41 is exhausted through passages 40, 44, 43, 45, 46, 47, 48 and 49 while at the same time the supply is cut off, as 37 does not align with 38, and the hammer falls. The air above the hammer passes out through a passage 42 and a valve 42b which can be adjusted to vary the blows which continue as long as air is supplied at 35. When this is connected to exhaust the falling parts are cushioned by the springs 30. Non-return valves 32 prevent air, admitted at 17 for jarring, from escaping at 35. The machine may also have rods moved vertically by fluidpressure cylinders in known manner to lift a finished mould from the table 3 which may be vibrated to facilitate drawing.

Class 20(2) [Also in Group XXIX] A hydraulic pit prop is provided with a spring-loaded valve 27, Fig. 5, of small flow cross-section opening in the direction of liquid pressure and operable either by the liquid pressure to relieve excess pressure in the prop or manually through a longitudinally displaceable rod 29, 30 to initially release the pressure when the prop is to be withdrawn, the valve 27 being interconnected, with axial play, by the rod 29, 30, with a spring-loaded main release valve 24 which opens in the direction opposite to the pressure in the prop, and can be manually opened by means of the rod 29, 30 after the valve 27 hasfirst been opened to initially release the pressure. The coupling between the rod 29, 30 and the valve 24, which comprises a piston 31 on the rod 30 guided in a closed chamber 32 in the valve 24, permits the valve 24 to open, independently of the valve 27, under the influence of liquid pressure in a liquid supply conduit 35, Fig. 2, adapted to be connected to the valve casing 22 when the prop is to be set, the valve 24 in this case acting as a non-return valve for the liquid being pumped into the prop.

Abstract: 430,000. Converting. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and THOMPSON, W. G., c/o General Electric Co., Wembley, Middlesex. Nov. 1, 1933, No. 30363. [Class 38 (ii)] [See also Group XXXVII] Control of a D.C. electric motor fed from A.C. mains through an arc rectifier is effected by an apparatus which varies the phase of ignition at will, and is also capable of being influenced automatically so as to shift the phase back in response to overload or excessive speed. The arrangement described includes two arc rectifiers 5, 10, Fig. 1 respectively feeding the motor armature 1 and its field 2. Each rectifier is controlled in action by an apparatus shown in Fig. 2, which comprises a small synchronous motor 20 driving rotary sparking balls 16, and a stationary but adjustable member 33 carrying sparking balls 17. Hand control of a shaft 24 adjusts the stator of the synchronous motor, whereas automatic control in response, for example, to excess current flowing in the coil 12 moves a spring retracted armature 36 so as to adjust the angular setting of the sparking balls 17. A magnetic zeroizing device 47 brings the carrier disc 38 of the armature 36 to its original relative setting when a solenoid 43 releases a detent 42, the release being arranged to take place in response to failure of motor field current. A similar control apparatus for the rectifier feeding the motor field is mechanically interlocked with the apparatus shown in Fig. 2 by a cam 28 and detent 31. Speed responsive devices may be used in addition to or in substitution for the current limit devices. Specifications 400,634; 406,999, 409,974, [both in Group XL], and 412,936 are referred to.

Title: Regenerative platinum catalyst reforming
Inventor: HAXTON MANFORD RAY
IPC: B01J23/96
Filed: 1960-09-12
Abstract: In reforming naphtha to an octane number greater than 95 CFR-R (unleaded) in the presence of recycled hydrogen and a halide-containing supported platinum catalyst in a multi-reactor system employing a swing reactor for periodic oxidative regeneration, water and water forming components in the system are controlled so as to maintain a water content in the naphtha effluent from the final reactor below 100 p.p.m.  Water is removed from the naphtha charge by (a) passing through a coalescer-settler to reduce the water content to 250 p.p.m., (b) passing over a conventional solid drier, e.g. bauxite, silica gel, molecular sieves or calcium sulphate to reduce the water content to below 40 p.p.m. and (c) stripping with excess process hydrogen to reduce the water content below 20 p.p.m.  Water is also removed from recycle gas, at least for the period immediately after returning a reactor of regenerated catalyst to operation, using a solid desiccant to lower the water content to a level below that corresponding to a -30 DEG F. dew point at atmosphere pressure, e.g. below 10 p.p.m.  Where the system is protected from oxidising regenerating gases by means of flue-gas-sealed valves, the carbon oxides content is reduced to below 1% mol, e.g. by scrubbing with water and/or ethanolamine.  Regeneration gases are dried to a water content below that corresponding to a 150 DEG F. dew point, e.g. by cooling by water spraying.  Solid desiccants are regenerated by contact with hot recycle gas.
