    摘要: Method and device for cell lysis in which a liquid mixture of bateria or eukaryoptic cells and of a lysing agent is produced continuously, and this mixture is caused to flow immediately in a steady stream inside a tubing (7), the flow rate of this stream being adjusted as a function of the diameter and of the length of the tubing (7) so as to obtain a substantially homegenous cell lysate at the outlet (8) of the said tubing.

    摘要: An apparatus for the thermal measurement of the texture of a porous body, including a measuring head, a measuring assembly and a processing and control circuit. The measuring head is provided with two identical cylindrical cells, a measuring cell and a reference cell, arranged in a furnace. The measuring assembly measures the mean temperature of the measuring cell, and measures a calorific effect in the measuring cell, and includes a calorific effect detector, a calibration circuit, a temperature regulator including a furnace heater. The measuring circuit supplies a temperature signal and a calorific effect signal to the processing and control circuit, which in turn controls the heater.

    摘要: A set of phase shifters associated with an array of radiators of an electronically scanning antenna are each controlled by a current-limiting amplifier which has an input stage in series with an electronic switch and an output stage connected to a source of operating voltage normally blocking a pair of diodes in the associated phase shifter. A feedback loop between the two amplifier stages includes another diode serving to stabilize the current flow through the phase-shifter diodes upon closure of the electronic switch by a control device and triggering of the input stage by a signal from a reference-voltage generator.

    摘要: A diode phase-shifting device for an electronically scanning antenna includes a cut-off device designed to operate when the phase-shifting diodes are switched to their non-conducting state, with a view to increasing the switchover speed. This device comprises mainly a low-voltage generator, a circuit breaker or switch, and a high-voltage generator. A switching from the low-voltage generator to the high-voltage generator occurs when the voltage at the terminals of the phase-shifting diode considered exceeds a given threshold value.
