Abstract: A process for the hydrotreatment of a diesel type hydrocarbon feed containing nitrogen-containing compounds is described, comprising a first step in which the feed is brought into contact with a catalyst in its oxide form, then a second step in which the feed is brought into contact with a dried catalyst comprising at least one organic compound containing oxygen and/or nitrogen.

Abstract: An operating table including at least three elements which are moveable in relation to each other; at least two actuators, each controlling displacement of two elements in relation to the other; a controller which drives each actuator; a sensor to detect a risk of collision of one of the elements with an obstacle when executing a displacement request of a first actuator; a controller which determines a corrective command order of a second actuator different from the first actuator upon detecting a risk of collision, wherein execution of the corrective command order by the second actuator causes cessation of the detected risk of collision upon subsequent execution of the displacement request of the first actuator; and a display to view the corrective command order.

Abstract: A process is described that can limit pressure drops during a catalytic hydrotreatment process carried out in a fixed bed reactor. The liquid feed and gaseous reactant are injected into the reactor either side of the bed and flow as a counter-current. Pressure drops are limited by homogeneously mixing solid catalytic and/or inert particles of different diameters in the bed.

Abstract: The control system comprises a microphone (7) linked to a receiver block (9) and delivering audio signals to a discriminating block (11) comparing the voice profile of the speaker with a particular authorized speaker profile recorded in a personal chip card (20) of the speaker. The authorized audio signals are then processed in a voice recognition device and an electronic control unit so as to selectively activate one of the actuators (3) of the operating table in response to a specific voice command uttered into the microphone and effected by an effector (16) actuated by the speaker.

Abstract: A composition is provided which is coextrudable with vinylidene polyfluoride permitting it to adhere to incompatible polymeric resins, the composition which has a base of an alkyl polymethacrylate and a thermoplastic polymer is comprised of:from 27 to 50 parts by weight of an alkyl polymethacrylate; andfrom 73 to 50 parts by weight of an additive itself constituted for 100 portions by weight of additive of:from 35 to 50 parts by weight of PVDF, andfrom 65 to 50 parts by weight of acrylic or methacrylic elastomer.This composition serves to produce vinylidene polyfluoride compounds capable of coating polymers which are non-compatible with vinylidene polyfluoride. When used as an adhesion agent, one can obtain by coextrusion, compounds of vinylidene polyfluoride and polymers non-compatible with the vinylidene polyfluoride.
