摘要:
A method for analyzing test results. The method comprises selecting selected control rules for verification from a plurality of stored, accessing selected test results, performing selected statistical analyses of the selected test results, and executing at least one action of a plurality of selected actions, wherein the plurality of selected actions is selected by a result of the selected statistical analyses. The plurality of selected control rules are arranged in a decision tree. The decision tree comprises a schedule for verification of the selected control rules. A selection of the test results is defined by the plurality of selected control rules. A selection of statistical analyses is defined by the plurality of selected control rules and the decision tree. There is at least one action selected by the decision tree.

Current pulses are conducted through an inductance by means of a switching transistor. The switching transistor is controlled by means of an amplifier and pulse shaper circuit in such a manner that a constant average direct current flows in a closed loop comprising said inductance and a recovery diode, resulting in a regulated, constant output voltage across two Zener diodes. This allows a particularly effective operation with relatively low power losses in said switching transistor as compared to the utility current at the output terminals, and the circuit operates reliably in a wide range of operating voltages.

The gas to be treated is cooled and partly condensed in two steps (3-4, 5-6), and the condensed fractions are distilled in a column (9). A part of the condensed liquid at the top of the column is subcooled in the second exchanger 5, expanded, and vaporized in counter-current to the gas to be treated. This permits the obtainment of cooling temperatures on the order of -80.degree. C. by means of a refrigerating unit (13, 20) operating at a temperature on the order of -30.degree. to -40.degree. C. Application to the recovery of a mixture of propane, butane and pentane from a petroleum refinery residual gas.

The starting gas is partly condensed in an exchanger 1. The refrigerating power is supplied, on one hand, by the free expansion of the liquid fraction and, on the other hand, by expansion in a gas-bearing turbine of the vapor fraction rich in hydrogen. A small part of this vapor fraction is used to feed auxiliary gases to the turbine, then is cooled in the exchanger 1, expanded and injected into the expanded liquid fraction so as to obtain a sufficiently low bubble point. The invention is useful in recovering hydrogen from purge gases of apparatus for ammonia synthesis, the purge gases being composed of hydrogen and less volatile components.

An apparatus for testing a device. The apparatus comprises a test control module and a test analysis module. The test control module is operable to generate and transmit first prober and handler (PH) requests to a supervisor module. The supervisor module is operable to transmit first PH commands to a prober and handler for execution thereof. The test analysis module is operable to generate and transmit second PH requests to the supervisor module. The supervisor module is further operable to transmit second PH commands to the prober and handler for execution thereof. The execution of the second PH commands are performed transparently to the test control module.

The invention relates to a power train for a hybrid vehicle, comprising two hydraulic machines (20, 22) including variable displacement, both of which are connected to a hydraulic pressure accumulator (24) which stores energy, a first hydraulic machine (20) being permanently connected to an internai combustion traction engine (2), and a second hydraulic machine (22) being connected, also permanently, to drive wheels (8) of the vehicle, characterised in that the two hydraulic machines (20, 22) are also interconnected by a linking means (10) that can be engaged or disengaged.
摘要:
Process for the purification of a gas containing selectively adsorbable impurities, of the type using several adsorbers with, for each adsorber, a cycle comprising the following operating phases which are offset from one adsorber to the next timewise by a fraction 1/n of the duration of the cycle in which n is the number of adsorbers, the cycle comprising substantially isobaric production at a high pressure of the cycle, this production comprising the admission of impure gas to be treated into an adsorber at a first end of the adsorber with circulation of this gas in the adsorber and simultaneous withdrawal from a second end of the adsorber of purified gas, the direction of flow in the adsorber from the first end to the second end being cocurrent and the opposite direction being countercurrent; regeneration of the adsorber comprising a decompression of the adsorber to a low pressure of the cycle, this decompression comprising at least one stage in which a residual gas is withdrawn countercurrent from the adsorber; and increasing the pressure to the high pressure of the cycle. A portion of the residual gas is mixed with the impure gas to be treated, and the rest of the residual gas is purged.

This process is of the type in which there is compressed in at least two stages 2, 6 a mixture of cooling fluids composed of constituents of different volatilities and in which, after the last stage 6 and after at least an intermediate compression stage 2, the mixture is partly condensed, the condensed fractions are expanded and vaporized in heat exchange with the fluid to be cooled before being compressed again. According to the invention, at least one of the condensation stages is carried out by sending to a distillation column 7 the mixture issuing from the corresponding stage of the compressor. This enables the thermodynamic irreversibility to be decreased and consequently permits a reduction of the specific cooling energy.
