Abstract: A dynamic earth anchor, which is forced from a tubular body, comprises a combination of a roof bolt and a tubular, deformable sleeve. The sleeve is insertable into a terrestrial borehole, at a closed end thereof, and then the bolt is inserted into the sleeve. This establishes an almost immediate restraint of the terrestrial formation in which the borehole is formed; the sleeve lockingly secures the bolt, and the bolt causes the sleeve to impress radial forces to the wall of the borehole.

The slit extends between the interior and exterior surfaces, tangentially intersecting with the interior surface. When the anchor is inserted, it is monitored in a substantially uniform cross sectional width regardless of minor diameter variations of the borehole, which cause sliding of the edge portions.

Abstract: An electron microscope stage is manually movable in three orthogonal axial directions and two orthogonal rotational directions by corresponding motion transmission systems. Four of the transmission systems employ telescopic rods and a connecting pin having three resilient independently compressible sections. The pin transmits torques from one rod to the other about their longitudinal axes. One section is resiliently secured to an aperture in the inner rod, the other sections are resiliently secured to mating axial slots in the outer rod to permit relative axial displacement of the rods. The independent resilient compression of each section compensates for wear or differences in dimensions between mating surfaces while maintaining tight resilient torque coupling without backlash between the pin and the rods.

Abstract: A bolt is fabricated from an elongated threaded rod by severing the rod along a planar surface angularly oriented with respect to a longitudinal axial plane through the rod. A cup-shaped nut has three equicircumferentially spaced lateral locking openings in the side walls adjacent the outer base wall thereof. The cup-shaped nut has an axial length greater than twice the diameter of the opening, with the opening in the half of the nut including the base wall. The nut is threaded onto the severed end of the rod with the base wall abutting the end of the rod. At least one locking opening is exposed to the inclined planar surface, and a pin is forced into the exposed opening with the inner end of the pin terminating within the nut and located immediately adjacent to the inclined surface thereby affecting a positive interconnection of the nut to the rod. In one embodiment the pin is a solid pin formed of a softer metal than the rod.

Abstract: A retaining pin assembly (16) for securing a replaceable earthworking tool (14) to a support member (12) includes a spring type pin (36) and a coacting sleeve (40). The pin assembly (16) is insertable through generally aligned openings (30,22) in the tool (14) and support member (12) and functions to lock the tool (14) to the support member (12) and to force an end portion (28) of the tool (14) into contacting relationship with shoulders (18,20) of the support member (12). Earthworking apparatus, such as impact rockbreakers and rippers, generally include a replaceable tool mounted on a shank or support member. Unless the tool is forceably held in contacting relationship with the support member, the retaining pin, tool, and support member are subject to damage. The retaining pin assembly (16) of the present invention secures the tool (14) and support member (12) in contacting relationship and maintains a continuous locking force between the tool (14) and the supporting member (12 ).

Abstract: The stabilizer, in a preferred embodiment thereof, comprises a generally tubular body which is axially slit, as in the prior art. According to one practice of the invention, the surfaces of the body immediately adjacent to the slit have ribs formed thereon which define bearing surfaces for clamping together, to draw the surfaces into proximity, narrowing the slit, thereby to contract the stabilizer to a constrained dimension approximately eight percent smaller than its free dimension. This is done to facilitate its insertion into an undersized bore. The novel method, then, in an embodiment thereof, comprises contracting an axially slit friction rock stabilizer by engaging the aforesaid ribs (formed thereon) with a tool, to contract the stabilizer to a reduced and constrained, approximately eight percent smaller, cross-sectional dimension, inserting the stabilizer into an undersized bore, and withdrawing the tool.
