    摘要: A downhole mud pressure change signal generator has a signal valve to variably resist the flow of mud down the drill string bore. The valve is powered by a bias driver and controlled by a holding magnet that is in turn controlled by a downhole instrument. The bias driver has a spring opposed fluid powered piston that moves in response to changes in fluid pressure drop across the signal valve. The valve in normally biased closed. The bias driver is resiliently connected to the valve such that when the piston moves the bias driver in response to fluid pressure that overcomes the spring, the valve is urged toward an open position. When the valve is open and signal pressure across the valve is low the spring exerts more force than the piston and the driver urges the valve toward a closed position.The valve is urged to move but not compelled and is subject to latching in desired positions without losing the power needed to move later. The bias driver is used to power a latch that holds the valve open or closed. The energy is invested in springs that move the latch when holding magnets permit the latch to respond to the bias. The holding magnets never depend upon a flux gap because they hold positions the springs have provided.

    摘要: In the preferred application, an acceleration compensation mass is supported in a downhole drilling related housing for independent movement along an axis in response to acceleration of the housing. A control member that moves relative to the housing in a direction parallel the axis to carry out the function of the housed apparatus is connected to a piston in a cooperating bore in the housing to displace fluid when the member moves. A second piston and cooperating bore in the housing is arranged to displace fluid when the mass moves. Fluid plumbing is arranged to connect the two hydraulic cylinders such that the mass and the member, if they move, must move in unison in opposite directions. When the housing is accelerated in the direction along the axis, both member and mass tend to move in the opposite direction relative to the housing but each piston opposes the other and no movement occurs if the pistons have effective areas proportional to the weights of the related member and mass. The member, however, can move irrespective of acceleration reaction forces in response to force applied to it relative to the housing, with the mass moving a proportional amount in the opposite direction.Alternate embodiments include linear compensators with the mass and member connected by racks and pinions to compel the opposite direction movements and a rotary compensator includes a rotating compenator mass rotationally connected to the member by gearing to compel rotation in opposite directions relative to the housing.

    摘要: The human breast is enhanced by enlargement by inserting body compatible fluids into the natural lactatous containments within the breast by flowing the liquid into the lactatous duct openings at the nipples. Flow is induced, from a source of pressurized fluid, by directing a jet of liquid into the duct opening, by pressing the fluid conductor against the opening or by penetrating the opening with a blunt needle or equivalent catheter. To ease penetration of the opening, suction apparatus is offered that distends the nipple to straighten the duct. Plugs are offered to enhance the fluid retention ability. The plug may be solid or valved to allow fluid flow only when a handling tool is inserted to manipulate the plug. Fluid emulsification apparatus is provided to condition fluids which may include saline aqueous liquid, compressible fluid, and autogenous materials individually or in combinations.

    摘要: A downhole signal generating mud pulser has a poppet and orifice signal valve to variably resist the drilling fluid stream. The poppet is upstream of the orifice and is moved by a piston in fluid communication with opposite flow related sides of the signal valve such that more pressure drop across the valve applies more piston force to open the valve. The poppet is spring biased toward the orifice and the piston force and spring balance when a preselected operating pressure exists. A servo valve controls flow in a by-pass loop to apply additional pressure to the piston to create a signal pulse when open. The servo valve is urged closed by flow in the servo loop and the closing is retarded by a dashpot to determine signal duration. The servo valve is spring biased to open and is automatically latched closed by a latch that responds to a solenoid actuated to release the servo valve. Options include replacement of the dashpot timer with a second latch position which latches the servo valve open to cause a signal pulse, the duration of which is determined by the controlling instrument which acts to release the latch from both positions.

    摘要: A drilling fluid pulse generator for use above a drill bit to produce pulsations in drilling fluid flow. An autocycling valve briefly interrupts the flow of fluid to bit jets to reduce the effective hydrostatic pressure at the drilling face and to hydraulic energy in the drill string to thoroughly scour the hole face when the briefly closed valve reopens. An alternate configuration provides a bypass route for fluid diverted from the bit, and the bypass includes jet nozzles to add energy to the return fluid stream to further reduce the effective hydrostatic pressure at the drilling face.
