Abstract: 1,273,945. Thermonuclear fusion. UNITED STATES ATOMIC ENERGY COMMISSION. 19 April, 1971 [11 Feb., 1970], No. 24175/71. Heading G6P. In a thermonuclear fusion reactor, deuteriumtritium pellets are injected into a liquid lithium mass and vaporized, to cause fusion, by a pulsed laser beam. The 14-mev neutrons released by the fusion, breed tritium from the lithium using the reaction Heating of the lithium is also effected during fusion and this is transferred, through a heat exchanger to a prime mover. The liquid lithium is injected into the containers vessel through jets which form a central cavity into which the pellets are directed. The lithium heated in the reactor supplies heat to a potassium-turbine system through a heat exchanger which also receives the tritium, produced in the reactor, through the niobium exchanger tubes. The tritium is removed from the potassium which supplies heat to a further, steam turbine plant. . (For Figures see next page)

Title: Improvements in methods of manufacturing viscose
IPC: D01F2/08
Filed: 1953-09-04
Abstract: <PICT:0741519/IV(a)/1> Cellulose xanthate, after being initially or extensively dissolved, is subjected to completion of dissolution and filtered, de-aerated and ripened in a system of vessels connected in series and provided with stirring mechanisms, the viscose being constantly forced with stirring through the vessels so that it completely fills the spaces in the vessels and is kept out of contact with the air, whereby the viscose is maintained in constant flow during its entire preparation prior to entering a spinning apparatus. Preferably the pumps which supply the viscose to the conduits leading to the spinning nozzles, are fed with a greater quantity of viscose than that which they take up and the excess is returned to the last mixing vessel of the series. Preferably also the stirring mechanisms in the vessels are provided with transverse bars arranged on stirrer arms so that they sweep with a small spacing over the peripheral surface and end walls of each vessel.  The various vessels may be provided with heating or cooling devices and pressure gauges.  Oils or pigments, e.g. titanium dioxide suspensions, may be added to the viscose.  As shown, cellulose xanthate is dissolved in the vessels 1 and several charges of viscose are fed into a blender 2 by means of a pump 3.  The viscose passes into a boiler 4 and air is removed by boiling under reduced pressure.  It is then forced through storage vessels 6 which are kept completely filled with the liquid.  The pumps 7 are provided with by-pass pipes 8. Ripening takes place as the viscose passes through the system and may be completed during the advance through filter 9 and vessels 10.  The viscose is then pumped through filter 11 and vessels 12. Further de-aeration may be effected, if desired, in a boiler arranged in the pipe-line at position 14.  Further filtration takes place in the filter 13 and the viscose is conveyed to the spinning apparatus by way of mixing vessels 15, pump 18 and, if necessary, through filter press 16.  The final pipes of the spinning apparatus may be connected to a collecting tube so that excess of viscose supplied thereto may be returned by means of pumps 19 through pipe 17 to one of the last mixing vessels 15, where it is intimately mixed with the main stream of viscose.  For taking up the excess of viscose if interruptions in the normal flow occur, there may be provided one or more vessels in parallel with vessels 6, 12 and 15 and filter 9.

Title: A process for the separation of diacetone alcohol methyl ether from diacetone alcohol
Filed: 1963-06-20
Abstract: <PICT:1002656/C2/1> Diacetone alcohol is separated from diacetone alcohol methyl ether contained in a mixture with mesityl oxide and water and water by (a) fractionating the mixture to give a distillate of water, mesityl oxide and diacetone alcohol methyl ether and a higher boiling fraction comprising diacetone alcohol, (b) cooling the distillate to form a water phase and an organic phase of mesityl oxide and diacetone alcohol methyl ether, (c) separating the phases and (d) returning the water phase to the fractionating column in step 1.  In a specific embodiment a mixture of acetone, methanol, water, mesityl oxide, diacetone alcohol, diacetone alcohol methyl ether and unresolved high boiling material is produced by interaction of acetone with NaOH or KOH and subsequent neutralization with HCl, H2SO4, H3PO4 or CO2.  This mixture was fed into preliminary fractionating column 3 at 2 and most of the acetone and methanol were distilled out via 4 and returned to the reactor.  The remaining material was fed into fractionating column 7 via pipe 6.  It might contain 5-20% water, 15-60% mesityl oxide, 30-65% diacetone alcohol and 3-12% diacetone alcohol methyl ether.  Both columns may be under reduced pressure and the lower end of column 7 may be below 150 DEG C.  The distillate from 7 was cooled in condenser 11 at 0-85 DEG  C. and separated at 13.  The aqueous phase containing principally water was returned to column 7 via 16.  The organic phase from 14 was distilled to separate the mesityl oxide and diacetone alcohol methyl ether, the latter optionally being returned to the initial reactor. 99% diacetone alcohol could be obtained by redistilling the higher boiling fraction from 9.

Abstract: 1,112,049. Hydrostatic transmission. T. BUDZICH. 10 June, 1965, No. 24678/65. Headings F2C, F2D and F2L. In a hydrostatic transmission for driving the front steerable wheels 17 of a tractor wherein motors 19 mounted on the wheels 17 are in closed circuit with a variable displacement pump 27 the displacement of which is varied in response to the delivery pressure by a servomotor 46 under the control of a valve 59, flow restricting means 75, 81 ensure a slow exhaust from the servo cylinder 47 and thus provide a slow increase in pump displacement which in the event of loss of traction at one of the wheels prevents rapid acceleration of that wheel. The control valve spool 62 is acted on by opposing spring pressure 71 and pump delivery pressure 25. Increased delivery pressure moves the valve spool 62 left to supply pressure fluid through a duct 72 to a poppet valve 75 which moves right and permits unrestricted flow to the servomotor 46 which reduces pump displacement against the bias of a spring 45 and thus reduces delivery pressure. A decrease in delivery pressure permits the spring 71 to move the valve spool 62 right and slowly exhaust the servocylinder 47 through the orifice 79 ot the valve 75, ducts 73, 80 and adjustable restriction 81. The pump displacement is thus slowly increased and increases delivery pressure. The spring 45 which biases the swash-plate 34 towards maximum displacement acts between pistons 41, 43, the latter of which is held in the position shown by pressure fluid in a chamber 44 supplied by a pump 89. Energization of a solenoid 100 moves a valve spool 99 down to short-circuit the pump 89 and vent the chamber 44 which reduces the displacement of the pump 27 to zero. Downward movement of the valve spool 99 also vents a line 97 supplying clutches between the motors 19 and wheels 17.
