Patent FR-2296917-A1 (FR)
Title: Fusion reaction by three stages of laser bombardment - with increasing energy and shorter duration also reflectors for second stage
Inventor: LUBIN MOSHE J
IPC: G21B1/03
Filed: 1975-01-06
Abstract: A method of operating a thermonuclear reactor consists of introducing heated, liquid lithium from a heat exchanger tangentially into a pressure vessel, then abstracting it from the vessel back to the heat exchanger, so as to form a central cavity in the pressure vessel, thermonuclear fuel pellets are intermittently, individually fed into this central cavity and bombarded by a laser beam to initiate a fusion reaction, the fast neutrons thus produced breed tritium in the liquid lithium, this tritium being removed in the heat exchanger, the heat produced in the heat exchanger drives a steam turbine to generate electricity. The laser beam is subdivided into successive pulses, a first pulsed beam oriented directly into the cavity zone on the path of the fuel pellets and having a selected energy and duration (esp. 1-2 Joules and 10-8- 10-9 secs) to evaporate and slightly ionise the pellets and thus form a plasma, a number of second, pulsed laser beams immediately following the first pulse and reflected from surfaces below the plasma to 'tailor' the plasma, these having a higher energy and shorter duration than the first beam (esp. 200-400 J and 10-8 -10-10 secs) a third pulsed high-energy firing laser beam having a still higher energy and still shorter duration (esp. 105J and 10-9-10-11 secs) and oriented directly into the 'tailored' plasma, to cause a fusion reaction inside it. Each of these steps is repeated for each individually introduced fuel pellet to obtain an optimum energy output level. Cryogenic magnetic fields are not required. Damage to the vacuum wall of the reactor by fast neutrons is substantially eliminated. A tritium breeder ratio greater than unity is obtd.

Title: Charge carrier prodn. for electro-graphic recording - by coating substrate with water-insol. protective film and aq. pigment dispersion
IPC: G03G5/00
Filed: 1975-01-23
Abstract: A charge carrier for electrographic recording is produced by coating a substrate (I) with a material forming a water-insol. protective film (II) and then with a dispersion of a sensitised, photoconducting pigment in an aq. soln. of an electrically insulating binder. After drying, the substrate is made conductive, if necessary, dried and conditioned, the softening, melting or dropping point of (II) being above the last drying temp.

Title: Access using comparison of multiplexer and keyword - has multiplexed output from disc store compared with keyword to control search process for access
IPC: G06F17/30
Filed: 1975-10-21
Abstract: A data processing system has a facility for a rapid access to the data store by simultaneous reading of data channels over a time multiplexing unit. Multiplexed data is transmitted to comparator stages for comparison with keying-in words in order to control the search process. The output channels from the magnet disc store are coupled over a control unit (2) to a multiplexer (3) handling twelve data channels each operating independently. The multiplexed outputs are transmitted to a bank of sixteen comparator stages (5). The comparator compare the output with the stored keying-in values and the result is transmitted to a search control unit (7). If the search criteria is satisfied (10) the process controller (8) generates an access control signal (9) to the memory output control circuits (2).
