IPC: F02M47/02
Filed: 1979-03-06
Abstract: La pression d'injection est produite par une pompe (16) et un regulateur de pression (28) et le carburant sous pression est distribue par une tuyauterie commune (20) a chaque valve d'injection d'un moteur. Les valves (22) sont des valves a pointeau du type differentiel, a commande hydraulique, dont l'ouverture et la fermeture, definissant la periode d'injection, sont produites par equilibre ou absence d'equilibre des pressions exercees sur le piston du pointeau. Les conditions d'equilibre sont gouvernees par le debit du carburant a travers les lumieres et orifices (72, 74, 78, 102) de vannes electro-magnetiques a tiroir (52) et par un dispositif temporisateur (38, 40) actionne par un moteur, qui determine le debut et la fin de la periode d'injection. Un courant controle de derivation provenant des vannes (52) peut etre recueilli par une tuyauterie basse pression pour retour au reservoir avec le surplus provenant d'un tuyauterie a haute pression (20).

Title: Electrohydraulic rotary brake
Inventor: CHARLAT PATRICE
IPC: F16D57/06
Filed: 1980-04-18
Abstract: An electrohydraulic rotary brake comprises an inner core, at least one energizing winding, a cylindrical amagnetic insert and an annular part outside the core and the insert. A cylindrical bore is excentric with respect to the cylindrical peripheral surface of the insert, recesses being provided with magnetizable sliding vanes and a brake fluid. On a rotary shaft, are mounted lateral flanges in fluid-tight manner, the inner core being fast to the rotary shaft and to the insert, all three being arranged so as to constitute a rotor for the brake. The annular part outside the core and the insert constitutes an annular stator to which the lateral flanges are fixed and with the bore excentric with respect to the peripheral surface of the insert constituting the outer part of the rotor. The recesses are formed in the cylindrical amagnetic insert and extend radially therein on both sides so that the vanes are movable between a position of complete freedom of the rotor with respect to the annular stator, in which they are positioned close to the rotor core, and a braking position in which they are positioned close to said annular stator, so that, under the effect of a variation in a pre-determined sense of the current passing through the energizing winding, the vanes can be attracted towards said stator and thus define peripheral chambers of different volumes which, by the forced passage of respective volumes of fluid from one chamber to the other, cause between the vanes and the stator a severe throttling and thus the braking torque of the rotor.

Abstract: An ink jet printer includes an arrangement to compensate the flight of the ink drops to correct for print errors caused by both drop interactive and environmental aerodynamic effects. Correction for drop interactive effects can be accomplished by the system represented in Fig. 2 or alternatively in one of the ways previously proposed. The additional correction for environmental effects is accomplished by adjusting the drop interactive correction by means of the system represented in Fig. 3. Such adjustment is first determined for static environmental factors including the climate in which the printer operates and the characteristics of the components of the ink jet printer. The adjustment is then changed dynamically for detected changes in air density of the environment.

Abstract: The valve consists of an elastic hollow valve body (2) which forms a prestorage chamber (8) for gas particles which form in the interior of the hermetically closed container and are to be vented. The hollow elastic valve body (2) swells under the pressure of the gas particles to be vented to form a hemispherical dome. As soon as the venting operation begins, the dome collapses again due to the exit of gas and again closes the container before the internal pressure of the container is balanced with the atmospheric external pressure. The diaphragm (4), ensuring the air-tightness, of the pressure relief valve is not raised by the pressure in the container but is lifted off from the valve seat (3) from the outside by the valve body (2) which swells due to the gas particles. <IMAGE>

Abstract: Methods and apparatus for preparing a grinding wheel and performing a grinding operation are provided in accordance with the teachings of the instant invention wherein a single treatment cylinder is employed to profile a grinding wheel. Initially, a circumferential speed relation which is smaller than one (1) is employed between the grinding wheel and treatment cylinder to cause initial profiling to occur in a manner to avoid damage to the binding material. Thereafter, when a desired minimum area of contact is achieved, the circumferential speed relationship is increased to approximately one (1) to achieve a profiling having a desired grinding efficiency. A rough grinding operation may then be commenced. Upon the completion of the rough grinding operation, profiling of the grinding wheel may be again established using a circumferential speed relationship which is small to achieve a fine grinding profile. Thereafter, a fine grinding operation may be performed.

Abstract: Method and apparatus for investigating earth formations according to the present invention include positioning an opening of a fluid reservoir in contact with the surface of a earth formation to be investigated and injecting the fluid at high pressures through the opening into the formation at frequencies within a range up to 1 khz to cause quasi-static flow in the formation. Streaming potentials generated in the formation by this flow are detected by appropriate electrodes and the output of the electrodes, representative of the generated potentials, is then processed to determine a characteristic response time of these streaming potentials. Thereafter, from a knowledge of the characteristic response time of the detected streaming potentials a measurement of the permeability of the formation is derived.
