Patent ES-8301331-A1 (ES)
Title: Variable displacement vane pump.
IPC: F01C21/08
Filed: 1981-10-30
Abstract: A variable displacement vane pump is provided in which a pair of rings having oval-shaped inner contours are rotatably mounted in side-by-side relationship. The rings are adapted for relative rotation to each other from a first position wherein the inner contours are in register with each other and a moved position wherein the inner contours are out-of-register, and means are provided for effecting the relative rotation, which include a gear system operatively connected to the rings. A rotor member is mounted for rotation within the rings and is formed with a plurality of circumferentially spaced recesses which extend the entire axial length of the rotor. Each of the recesses carries a pair of vanes in abutting relationship. The vanes are mounted for radial movement in the recesses and are adapted for slidable contact with the inner contours of the rings. The vanes form two side-by-side rows of vanes with each row in tracking relationship with the inner contours of the rings. With the inner contours rotated to the first position, rotation of the vanes will pump a maximum volume of fluid through the pump and with the inner contours rotated to the moved position, the vanes will pump a reduced volume of fluid through the pump.

When clamping the cutting insert there is only a point contact between the screw and the cutting insert hole.
Patent ES-8300842-A1 (ES)
Title: Multiple stage hydrocarbon conversion with gravity flowing catalyst particles.
IPC: C10G59/02
Filed: 1982-01-04
Abstract: A multiple stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones, in each of which the catalyst particles are downwardly movable via gravity flow. At least four reaction zones are utilized, with the fresh feed and hydrogen reactant stream being split between the first and second reaction zones. The flow of that portion introduced into the second zone is restricted. The effluent stream from the first reaction zone is also restricted and then combined with the effluent from the second reaction zone. One portion of the combined effluent streams is introduced into the third reaction zone, and the remaining portion is restricted in flow, combined with the effluent stream from said third reaction zone, and introduced into the fourth reaction zone. This technique decreases the mass flow to the first three zones and increases the pressure drop experienced within the entire conversion system, thus serving to alleviate the problems associated with the occurrence of stagnant catalyst areas as a result of catalyst particles being "pinned" within a reaction zone and thus unable to assume a downward, gravity flow pattern. Restriction of the second zone feed and first reaction zone effluent insures a higher pressure in the first zone.

Abstract: A trailer braking system for a tractor-trailer configuration is of the type which includes a primary air reservoir (12) on the tractor (10) which supplies an auxiliary air reservoir (22) on the trailer (18). A pedal brake actuator (26) on the tractor selectively provides control air from the primary air reservoir (12) on the tractor to a relay valve (42) on the trailer which control air causes air from the auxiliary air reservoir (22) to be directed to the brakes (46) on the trailer. There is provided a secondary source of control air on the trailer in the form of a control air reservoir (54) having a volume significantly smaller than the volume of the auxiliary air reservoir (22). The control air reservoir (54) is supplied control air through a first line (59) from the auxiliary air reservoir (12). A second line (60) from the control air reservoir (54) goes to the relay valve (42) and includes a check valve (62) therein to only allow the control air to be capable of passing from the control air reservoir (54) to the relay valve (42). A normally open first valve element (64) is in the first line (59) and a normally closed second valve element (66) is in the second line (60). An electrical solenoid (96) for the first valve element and the second valve element (66) which is actuated by an electrical signal which is produced when control air is provided by the pedal brake actuator (26) closes the first valve element (64) and opens the second valve element (66) to provide control air from the control air reservoir (54) to the control valve (42) prior to control air from the primary air reservoir (12) through the pedal brake actuator (26).

Patent ES-8705560-A1 (ES)
Title: Method and apparatus for acoustic dipole shear wave well logging.
IPC: G01V1/44
Filed: 1985-12-27
Abstract: The shear velocity of a formation traversed by a fluid-filled open or cased borehole is obtained. Waveforms are obtained from a dipole acoustic investigation of the formation relative to a common location in the borehole. In a direct technique, the bandwidth of the waveforms is substantially bounded by an upper frequency fu at and below which energy traveling at the shear velocity is dominant. Moreover, the bandwidth of the waveforms is concentrated near the frequency fu. The shear velocity of said earth formation is determined from waveforms obtained from a broadband dipole acoustic investigation. The waveforms are low-pass filtered, and an interim shear velocity vs is determined. Vs is first obtained for an initial fcut, and subsequently for additional decreasing values of fcut, until a preselected relationship between fcut and vs is satisfied. The last-determined vs is the shear velocity. In another embodiment the flexural mode phase velocity is determined as a function of frequency from the waveforms. If a low frequency asymptote is identifiable, it is reported as the shear velocity. If not, a plurality of additional curves of the flexural mode phase velocity as a function of frequency are theoretically determined, based on respective estimated shear velocities. These curves are respectively fitted to the curve determined from the waveforms, until a satisfactory least error fit is achieved. The last-estimated shear velocity is reported as a shear velocity of the formation.

Filed: 1991-07-01
Abstract: An improved arbitration apparatus for a computer network of the type having a plurality of communicating nodes, the nodes communicating by a shared bus, wherein an arbitration apparatus located in each node, functions by assigning to each node an initial arbitration count number; the apparatus includes means, in each node, for testing for the presence of a carrier signal on the bus, indicative that another node is transmitting on the bus; and means, responsive to a number of counted quiet slots (when there is absence of carrier signed on the bus) equaling the arbitration count number, for beginning transmission of a message on the bus. Also, a means, responsive to a node winning an arbitration, changes the arbitration count number of each node. The apparatus reserves a specified quiet slot for a node having no knowledge of the history of arbitration to transmit it. Responsive to a node beginning communication during a deaf node quiet slot, the apparatus reassigns an initial set of arbitration count numbers to the nodes, for resetting a clock in each node.

Abstract: Biologically active reagents are prepared from particles of copolymers having polyoxyalkylene side chains, each side chain having a molecular weight of at least 88. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through reactive groups on the particle surface. These reagents are used to advantage in analytical elements and methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents. Adsorption of undesirable proteins on the particles of the reagents was considerably reduced because of the specific composition of the particles.
