Title: Method of generating the energy in tokamak thermonuclear reactor
IPC: G21B1/05
Filed: 1979-07-27
Abstract: The method comprises creation of toroidal magnetic fields and intermittent formation of plasma columns in two working volumes with a gas mixture of isotopes of hydrogen, those working volumes being located within the toroidal magnetic fields and being formed by toroidal discharge chambers (24, 25) placed one above the other, symmetrically in relation to the main horizontal plane of the tokamak reactor and enclosed in a common blanket (18), surrounded by a protection means (23) against radiation and provided with a means fur ensuring the circulation of the heat-carrying agent and comprising a plurality of interconnected pipes (19) placed in the body of the blanket (18). The plasma column in each of the chambers (24, 25) is formed by way of cyclic remagnetization of the inductor (1) of the reactor, whereas the plasma column is kept within the limits of each of the chambers (24, 25) by means of a steering magnetic field, of which the intensity and orientation along the circular axis of each of the chambers (24, 25) are changed synchronously with the remagnetization of the inductor (1). Continuous heating of the blanket (18) and generation of thermal energy therein is ensured by constant irradiation of the blanket (18) with fast neutrons produced in the course of thermo-nuclear fusion reactions in the plasma columns, which occur alternatively in each of the chambers (24, 25) during power input into those chambers from an external power source for the purpose of additional heating of the plasma.

Patent GB-2101668-A (GB)
Title: Double throw lock
Inventor: MANDER MICHAEL GEORGE
IPC: E05B63/00
Filed: 1982-01-29
Abstract: A dead bolt 12 is movable relative to a casing 10 between a first position wherein it is retracted with respect to the casing, a second position (Fig. 6) wherein it is partially extended from the casing, and a third position (Fig. 7) wherein it is fully extended from the casing. The dead bolt 12 is composed of a main bolt member 27. A rotatable cam lobe 23 of a key-operated cylinder lock 22 engages in a recess 37 in the main bolt member 26 in order to move the dead bolt 12 between its retracted and partially extended positions. Movement of the dead bolt 12 from its retracted position to its partially extended position causes the auxiliary bolt member 27 to extend from the main bolt member 26 and thereby define a further recess 42 in which the cam lobe 23 can engage to move the dead bolt between its partially extended and fully extended positions. In the event that the auxiliary bolt member 27 does not extend from the main bolt member 26, a tall piece 48 thereon engages the cam of the lock unit 22 and obstructs the latter from extending the dead bolt 12 into its fully extended position. <IMAGE>

Patent GB-2154831-A (GB)
Title: Impedance matching circuit
Inventor: BLOMLEY PETER FRED
IPC: H04M1/60
Filed: 1983-07-15
Abstract: In a telephone instrument line output circuit an impedance (Zt) is connected across the line. A negative impedance, e.g. provided by a DC amplifier (212) in a positive feedback loop, is connected in parallel with the impedance (Zt). The line therefore 'sees' the parallel combination of these two impedances. This allows a relatively low value of the impedance (Zt) to be employed thus reducing the voltage drop between the circuit and the line. <IMAGE>
