Title: Process and appliance for producing intense magnetic fields for the purpose of confining a plasma
IPC: H05H1/04
Filed: 1961-05-26
Abstract: 942,706. Thermonuclear apparatus. J. G. LINHART. May 26,1961 [July 5, 1960; April 17, 1961], No. 19073/61. Heading G6P. A process for producing intense magnetic fields for confining a plasma to enable fusion reaction to take place in it, comprises introducing a gas peripherally into a highly evacuated cylindrical enclosure immediately after a central column of plasma has been produced in it, and subjecting the gas to a series of electrical discharges coaxial with the central column of plasma causing the gas to assume the shape of a centripetally moving annular column which compresses the field confining the central column of plasma. The cylindrical enclosure shown in Fig. 2 includes near its periphery a cylinder 5 of porous ceramic material or pierced with orifices such as 6. A plurality of concentric circular electrodes such as 9, 10 pass through electrically insulating parts of the circular base 7. A central column 1 of plasma, consisting either of a mixture of deuterium and tritium or of a mixture formed by vaporizing a tritiated lithium deuteride wire by means of electrical discharges, is set up round the axis of the apparatus and a blast of gas is introduced via pipes 18. When the gas reaches the vicinity of electrodes 9, 9<SP>1</SP> a condenser is discharged across the electrodes to form an annular column of ionised gas and to impart a centripetal movement to the column;when the column reaches electrodes 10, 10<SP>1</SP> a further discharge gives an extra centripetal impulse causing the column to compress the magnetic field surrounding the plasma column 1. There may be more than two sets of electrodes and the blasts of gas passing through the wall 5 may follow one another at a rate so chosen that a plurality of concentric annular columns can pursue one another from one pair of electrodes to the next. The gas may be the same as that of the plasma or may be of an element having an atomic number less than 31, for example lithium or aluminium. Specification 889, 890 is referred to.

Filed: 1933-07-08
Abstract: 415,557. Tea making. NEWMAN, F. H., 3376, North Oakland Avenue, Milwaukee, Wisconsin, U.S.A. July 8, 1933, No. 19436. [Class 129.] A tea-pot is provided with a float supported in the infusion and adapted to lift the tea-leaves out of the infusion after a predetermined interval ; the time interval is determined by the rate of flow of water from a receptacle carried by the float, the water leaking away through a variable orifice. As shown the device comprises a perforated cylinder 8, fitting in the pot 5 and attached to a float 10, and an upper receptacle 15 fitting in the open top of the cylinder 8. The receptacle 15 has a central aperture 20, in which is rotatably mounted a tube 19, the friction of the tube in the aperture 20 being sufficient to hold the tube in any position. The bottom of the receptacle 15 is provided with a hole 21 near the aperture 20, and an overlapping flange 18 on the bottom of the tube 19 has a number of orifices 22 of varying sizes, any of which can be brought into register with the hole 21 by rotation of the tube. The tea leaves are placed on top of the float 10, and boiling water is poured on them through the tube 19 and also into the receptacle 15 round the tube 19. The weight of the water in the receptacle 15 maintains the float and tea leaves submerged in the water in the lower part of the pot to make the infusion. The water in the receptacle 15 leaks away through the apertures 21, 22, at a rate depending on the size of the aperture 22 which has been brought into register with the hole 21, and after a time the weight of the water in the receptacle is insufficient to overcome the buoyancy of the float, which therefore rises and lifts the tea leaves out of the water to prevent further drawing of the tea.
