Title: Spray drying and solvent recovery system
IPC: B01D1/18
Filed: 1937-06-09
Abstract: <PICT:0475635/III/1> The volatile solvents are recovered from solutions of thermoplastic heat-sensitive materials, such as vinyl and styrol resins, by heating and spray-drying the solution in a chamber 21 in the pre <PICT:0475635/III/2> sence of a hot inert gas admitted by the pipe 41 to precipitate the resins at a temperature below their softening point, recovering the solvent, and recycling the inert gas.  The gas may be nitrogen, hydrogen, methane, hydrogen-methane mixtures, flue gases, vinyl chloride, acetone vapour, air, and mixtures of these.  The solution is fed from tanks 11, 13 by a pump 55 and pipe 34 to a centrifugal sprayer comprising an inner cone 33, an intermediate slotted chamber 35, and an outer slotted distributor 36, all rotating together, which throws the solution in atomized condition into the hot gas in the chamber 21 provided with conical guide surfaces 23, 25.  The hot gas is drawn from a heater 123 by a compressor 131 and forced into the chamber 21 through pipe 41 p  and conduit 27.  The gas is maintained in a whirling condition by drawing it off through a pipe 47 by means of a compressor 51 and forcing it back into 21 by a pipe 45.  The mixture of separated solids, vapours and gases is drawn off by a fan 63 and forced into a separator 59, from which the solids pass to a receiver 65, while the vapours and gas pass by a pipe 71 to a bag filter 69 where residual solids are separated and fall into a chamber 73.  The gas and vapours are forced by a fan 83 through pipes 79, 80 into a heat-exchanger 77, from which the condensed solvent passes to a receiver 89, while the gas passes, by pipe 87 to a brine condenser 85.  The gas and residual condensed solvent pass from 85 to a separator 99, from which the solvent flows to 89 while the cooled gas passes by pipe 183 to act as the cooling agent in the heat-exchanger 77.  From 77 the gas passes by pipe 121 to the heater 123 to be recycled.  In a modification, the heat-exchanger 77 and condenser 85 are replaced by a single heat-exchanger, which may be water-cooled.

Title: Nuclear reactior installation
IPC: G21C1/03
Filed: 1972-04-06
Abstract: 1314499 Cooling reactors COMMISSARIAT A L'ENERGIE ATOMIQUE 6 April 1972 [16 April 1971] 15966/72 Heading G6C A nuclear reactor installation comprises a core 1 disposed within a primary vessel 2 which is surrounded by, and coaxial with, an outer containment vessel 11 containing heat exchangers 9, transverse passages 6 being provided for the conduction of coolant from the primary vessel toward the outer vessel, and circulation of coolant between the vessels 2, 11 being enforced by pumps 18 whose lower ends are surrounded by open-bottomed chambers 17. In the embodiment shown the heat exchangers 9 are enclosed within respective vertical sleeves whose lower ends have orifices 8 for the inlet of coolant, e.g. sodium, from the passages 6 and whose upper ends have orifices 10 for the discharge of coolant into the vessel 11. Within each chamber 17, the associated pump 18 is connected with the coolant through inlet orifices 19, the coolant being supplied to a box 21, below the core, by a pipe 20. In another embodiment (Fig. 2, not shown) the transverse passages 6 extend from a location adjacent the upper region of the core and each lead to a vertical sleeve which surrounds the upper part of the associated heat exchanger. Coolant thus enters the heat exchangers through the upper orifices and is discharged to the vessel 11 through the lower orifices, the lower parts of the heat exchangers being disposed below the transverse passages. The arrangements are said to promote coolant circulation by natural convection, especially in the event of pump failure, and enables the primary vessel to withstand damage which might be sustained in a maximum credible accident (core explosion). Lateral core-shielding assernblies can be provided. The reactor may be a fast neutron type having a core composed of fissile and fertile material (the latter arranged in top, bottom and lateral blankets).

Abstract: 552,701. Electric-welding. DORRAT, J. A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 13, 1941, No. 16111. [Class 83 (iv)] A machine for spot welding relatively large and thick sheets in ship-building &c. comprises a gantry the central bridging member of which carries a welding head supporting a pair of spaced depending electrodes movable with respect to a corresponding pair of fixed electrodes upstanding from the bed of the gantry, the movable pair being connected to opposite ends of a transformer or like and the fixed pair being connected together so that welding current passes from one movable electrode through the work at one spot and is conveyed externally of the work so as to pass to the other movable electrode through a second spot in series with its passage at the first spot. By simultaneously welding at two spots the inductance in the circuit is minimized and maintained relatively constant for different locations of the spot welds in relation to the margin &c of the sheet. Two pairs of electrodes 3, 3a, 4, 4a, may be used one electrode 3, 4 of each pair being movable and connected to the opposite poles of a transformer 6, the stationary electrodes 3a, 4a being connected directly together. The pairs of electrodes are spaced apart at such a distance that the electrical impedance in the plane of the sheet is high relatively to that of the transverse path through the sheets. The electrodes 3, 4, which may be spaced apart say 8 inches which is equivalent to twice the pitch of the spots in the finished work, are ciltried by separate slides 12, which are reciprocated by fluid pressure rams in guides in a head 15 carried by a frame 1 extending from an arm 1d projecting laterally from the bridge 1c of a gantry. The electrodes may be spaced about 5 feet from the limbs 1a, 1b of the gantry, and the frame 1f extends about 5 feet in front of the gantry so that long sheets say 5 feet wide and ¢ inch thick, may be passed straight through the gantry and moved through about 5 feet from one side to the other as well as being turned for effecting transverse welds. The electrodes 3a, 4a are secured by clamps to a copper or like conducting block 40 mounted on the top of a pillar 5. The electrodes 3, 4 are connected to the slides 12 through horizontal carriers 8, 9 provided at their rear ends with lugs 8c, 9c which are connected by short U-shaped flexible leads 26, 32 to conductors 28, 34. Such conductors are secured to flat conductor bars which are close together and pass through an insulating block 30 and are connected to the secondary terminals of the transformer which is mounted in the frame 1f.

Title: Improvements in bicycle locks
IPC: B62H5/14
Filed: 1920-06-15
Abstract: 169,005. Tunbridge, F. F. A. June 15, 1920. Guarding against unauthorized use. - Relates to bicycle locks of the kind wherein a bolt or piece of metal is bent to form two arms at right-angles to one another, one of the arms A being arranged to swing between spokes of the road wheel and the other arm B acting as a pivot rotatable in an attachment C upon the bicycle frame and capable of being locked. According to the invention, the arm B is adapted to be locked by a spring plunger D or by a spring or gravity actuated ball, which is adapted to be released by a key G inserted axially into the arm, or, in the case of the gravity ball, by inclining the machine to the necessary angle. By the use of a pin M or by burring-over the lower end of the arm B, the piece is prevented from being withdrawn from the attachment. A pin L which, when the piece is between the wheel spokes, occupies a position in its groove just at the side of the keyslot F, prevents the piece from being released and. turned into inoperative position except by a key notched, as shown, to clear the pin L. By arranging the pin L and plunger D at different positions relatively to the length of the key-slot and by having different depths, lengths, and widths of key-slots, variety can be given to the shape of the key required for operating the device. When in position paralel to the wheel, the arm A is retained by a spring plunger I engaging with a socket on the attachment, and the plunger may be releasable either by a head O or by inserting the key into the attachnent. According to the Provisional Specification, the arm A may be held in inoperative position by a spring plunger engaging with the socket in the axis B.
