Abstract: Abstract of the Disclosure An apparatus for treating rock surrounding a wellbore comprises a hollow elongated housing having nozzles radially mounted therein, which are projectable externally thereof. Each nozzle has a through passage communicating with the in-ternal space of the housing to pass the flow of a fluid with an abrasive filler therethrough.  The external end faces of the nozzles are shaped so as to press against the wall of the casing.  Each through passage of the nozzle has an increa-sed-diameter portion at the end thereof, facing the casing wall. The body of each nozzle has auxiliary passages, each such passage having one end thereof communicating with the increased-diameter portion of the through passage and the other end thereof communicating with the space externally of the nozzle, the auxiliary passages affording the flow of the fluid with the abrasive filler from the space defined by the said increased-diameter portion of the through passage and the adjacent casing wall, as the nozzle is closely pressed against the casing.

Abstract: ABSTRACT OF THE DISCLOSURE          Detachable cultivator teeth shovels and the like are usually bolted to the implement shank and these bolts corrode or rust, or get clogged with dirt or become burred over thus making detachment extremely difficult.  The present device in-cludes a quickly attachable and detachable implement to a shank which includes pins extending through the shank and the imple-ment and being engaged by keyhole wedge slots of a locking plate which pulls the implement tightly to engagement with the shank by slight downward movement of the plate, the keyhole slots of which engage over cut away portions near one end of the pins.  A set screw screw threadably engages the plate and is then tightened so that the inner ends bears against the shank and holds the assembly firmly in position yet enables the implement to be detached readily and easily when desired.

Abstract: TITLE            HYDRAULIC MOTOR WITH ORBITING DRIVE MEMBER     ABSTRACT            A working member, i.e., an eccentric drive ring having internal teeth, orbits about a driven pinion having a lesser number of teeth to achieve gear reduction.  Hydrau-lically expressed divider vanes on the orbiting drive ring engage the inner periphery of a surrounding fixed ring to define working chambers between the outer periphery of the drive ring and the inner periphery of the fixed ring. Port plates on opposite sides of the drive rinq are respec-tively exposed to high and low pressure fluid.  Valving occurs when slots on opposite sides of the drive  ring are exposed to ports on the port plate as the result of the orbital movement of the drive ring, so as to establish fluid flow paths to and from the working chambers.
