Abstract: Abstract:     A directional drilling tool permits the control of the drilling angle of a drill bit through the repeated placement or removal of a ball within the mudstream.  The ball activates a clutch mechanism within the directional drilling tour.  The clutch mechanism upon activation, locks the exterior of the directional drilling sub to a fixed annular orientation.  Simultaneously, there is activated a deflection mechanism to deflect a drive shaft which is normally fixed in an aligned straight position within the tube body, so as to shift the normally straight aligned shaft to a deflected position, causing the bit and the sub to angle for drilling at a controlled angle of off-set from the vertical.  A second embodiment utilizes a deflection cam engaging the drive shaft directly to effect the deflection of the shaft.

Abstract: An apparatus for metering, measuring, or dosing flowing media. A distribution slide valve is disposed in a housing between an inlet and an outlet. A metering piston is disposed in a chamber of the housing and divides the chamber into a first and a second metering chamber. The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet. Transfer passages are disposed on the periphery of the slide valve for selective connection of connecting passages to the inlet, the outlet, and the metering chambers. A transverse connection of the slide valve connects a central control channel thereof to the inlet via a first one of the transfer passages in either of the end positions of the slide valve. Each end of the latter is associated with a hydraulic control chamber into which the control channel opens. Relief passages connect the control chambers to the outlet. A piston rod connected to the metering piston extends axially displaceably through the larger diameter control channel, with the slide valve being axially movable relative to the piston rod. Sealing elements are disposed on the piston rod, with the control channel being adapted to be alternately sealed off relative to one or the other of the control chambers via these sealing elements.
