Title: Reciprocating pulser for mud pulse telemetry
Inventor: HAHN DETLEF
IPC: E21B47/18
Filed: 2006-05-24
Abstract: A method of transmitting pressure pulses from a downhole location through a flowing fluid in a wellbore comprises using a linear actuator to controllably move a reciprocating member axially back and forth between a first position and a second position to at least partially obstruct flow of the flowing fluid to generate the pressure pulses. A reciprocating pulser for generating pressure pulses in a fluid flowing in a wellbore, comprises a fluid passage that allows flow of the fluid through the pulser, and a reciprocating member. A linear actuator is coupled to the reciprocating member, such that the linear actuator moves the reciprocating member in a first axial direction and then in a reverse direction to at least partially obstruct flow of the fluid through the pulser to generate pressure pulses in the flowing fluid.

Title: Connector with lockable lever
Inventor: OKUDA KATSUMASA
IPC: H01R13/629
Filed: 2008-02-14
Abstract: A first connector 11 comprises a first body, a guided portion 25 and a stopper-releaser 32. A second connector 12 comprises a lever 45 and a lever stopper 46. When the connectors are completely disengaged, the lever stopper locks the lever so that it cannot rotate. To engage the connectors, they are first moved to a preliminary fitting position (Fig 3) without rotating the lever. In this position the stopper releaser 32 moves the stopper 46 to a position which allows the lever to rotate. Rotating the lever causes guiding portion 54 to engage depression 30 of the guided portion and so pulls the connectors together to a fully fitted position. Disengagement is the reverse of this. The stopper-releaser may be integral with the guided portion.

Title: Hybrid vehicle control apparatus and method
Inventor: BOWMAN TIMOTHY JAMES
IPC: B60K6/30
Filed: 2009-01-21
Abstract: A hybrid vehicle has an internal combustion engine 2 and a flywheel 9. Storage and release of energy by the flywheel 9 is enabled by a continuously variable transmission 10 and clutch 11 under the control of an electronic module 14. The amount of energy transferred from the vehicle one to the flywheel 9 during a deceleration manoeuvre is maximized by increasing the engine speed. As a result, the engine does more work against the braking force of the accelerating flywheel and causes the flywheel to spin up to a higher rotational speed. A braking system vacuum pump assists the operation a flywheel housing vacuum pump. Periodic braking effort modulation may be provided to prevent seizure of braking system components while minimizing concomitant losses.

Title: Multi-stage amplifier with multiple sets of fixed and variable voltage rails
Inventor: TUCKER JOHN C
IPC: H03F1/02
Filed: 2008-01-15
Abstract: A signal processing system and method utilizes a multi-stage amplifier (400) to amplify an input signal (108). The multi-stage amplifier (400) uses a mixed set of voltage rails (Vdd_o, Vss_o,.., Vdd_n, Vss_n) to improve the operating efficiency of at least one of the amplification stages while allowing other amplification stages to operate in a predetermined operating mode. Efficiency of at least one of the stages is improved by supplying at least one variable voltage rail to an amplification stage of the multi-stage amplifier (400). The variable voltage rail varies in response to changes in an input signal voltage to the amplification stage. Accordingly, at least one amplification stage utilizes a variable voltage rail, and all amplification stages are supplied with a set of voltage rails that provides sufficient input signal headroom, thus, providing amplification stage efficiency and adequate voltage to allow operation of all amplification stages.

Abstract: 733,165. Valves. AIRNESCO PRODUCTS, Ltd. July 21, 1953 [April 21, 1952], No. 10003/52. Class 135. [Also in Group XXVIII] The emission of pressure fluid in a series of rapidly recurring blasts through a discharge orifice O and from a chamber 5 of a blast gun is controlled by a valve V operated by a piston 1 reciprocated within a cylinder 2 against the action of a spring 10 when the pressure in the chamber is sufficient to overcome the force of the spring, and to ensure that the valve will remain in the closed position when the gun is in operation and until the pressure in the chamber is at the maximum value, a compression spring 11 is disposed between a collar 11<SP>1</SP> secured to the valve spindle 8, on which the piston slides, and one face of the piston, the piston being provided with a passage 22 so that there is a balance of pressure between the chambers 5, 20. The cylinder 2 is closed by a cap 12 housing a valve 15 operated by a plunger 18, and opening of that valve allows the pressure in the chamber 20 to fall to atmospheric, the pressure in the chamber C forcing the piston along the spindle 8 to compress the springs 10, 11 until the thrust of the spring 11 is sufficient to displace the spindle relative to the piston 1 and unseat the valve head V. When the pressure in the chamber C has been released the pressures on opposite sides of the piston are balanced and the spring 10 moves the valve V onto the valve seat 6<SP>1</SP>.

Abstract: 734,013. Counting-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 23, 1953 [April 23, 1952], No. 10263/52. Class 106 (1). In an electromagnetic-relay counting circuit, one particular relay only changes state at each of one set of alternate half-cycles of the drive contacts, and one of the other relays changes state at each one of the other set of alternate half-cycles. The sequence repeats only after at least four cycles. An arrangement, Figs. 1 and 1a, for counting, in a radix of sixteen, complete cycles of changeover contacts D, uses five sidestable polarized relays, each having two opposed coils. Tn a modification, Fig. 2, single-coil sidestable polarized relays are connected to voltages of opposite polarity, a change of state of a relay being effected by energizing its coil in the reverse sense to the last energization. A further arrangement, Fig. 6, employs simple two-winding relays. Make-before-break driving contacts D whilst operated maintain a holding circuit B<SP>1</SP> for relays 2-5 and whilst unoperated maintain a'holding circuit A<SP>1</SP> for relay 1. To avoid misoperation, the contacts D may be replaced by two pairs of changeover contacts D1, D2, Fig. 6a, operated in sequence. The circuit may be modified, Figs. 7 and 8'(not shown), for counting in a radix of ten. A radix-of-four counter, Fig. 5, employs simple single-coil relays each of which, on operation, completes a holding circuit for itself. Release is effected by short-circuiting the coil.
