Abstract: The garment folding aid has two bed subassemblies that are laterally telescopically adjustable and retained in selected adjusted positions by detent mechanism. To the remote vertical longitudinal edge portions of the subassemblies there is mounted the lower mounting rails of hinges while the lateral opposite mounting rails of the hinges mount folder flaps. The web of each hinge which extends between its mounting rails resiliently urges the said opposite mounting rails to extend vertically upwardly, the webs being of a greater flexibility than the mounting rails. Hand hold openings are provided in the flaps to facilitate moving the subassemblies to adjust the width of the folding aid. Corner portions of the flaps on one longitudinal end of the subassemblies are cut at an angle to make the flaps more ergonomically friendly when moving the flaps during a garment folding operation.

Abstract: The drilling apparatus includes a safety sub mountable to the drill string outer end to retain the combination of an overshot assembly and an overshot adaptor extending within the drill string outer end during a drilling operation and preventing the drilling tool moving out of the drill string until the sub is removed. The overshot assembly has a fluid seal between the overshot tube and the drill string and a fluid bypass channel with/a valve for blocking axial outward flow through the channel when the overshot adaptor is separated from the overshot assembly and when connected thereto, retaining the valve in an open condition. When the overshot adaptor is removed from the overshot assembly, the overshot assembly is fluidly propellable to the bit end. A disconnect tool facilitates the removal of the adaptor from the sub.

Abstract: The grouting apparatus includes a tubular body, an outer end closure removably mounted to the outer end of the tubular body and a nozzle mounted to the inner end of the tubular body to form a container for grouting material. The tubular body has a landing shoulder seatable on a drill string landing shoulder. The closure includes an overshot coupling member and a head having an inlet passage opening to the tubular body. A piston and a sleeve are axially movable in the tubular body to force the grouting material out of the container, the sleeve blocking flow through the piston as the piston moves inwardly, but after abutting against the nozzle, opening a bypass channel from outwardly of the piston, through the piston and to the nozzle tube. Upon the sleeve moving inwardly relative to the piston, the fluid outwardly of the container may be pumped through the container to mix with the grouting material that was dispensed into the container prior to the container being inserted into the drill string.

Abstract: The golf club in a position of use of initially impacting a golf ball at ground level has a shaft that is joined to the hosel in a horizontal plane that is parallel to ground level and at an elevation that is the same as maximum vertical spacing of the toe from the ground level and thus the plane is at an obtuse angle to the shaft central axis. The club head includes a toe bar mounted to the club head main body rear portion and is of a greater height than its transverse width and thickness and has a center line that intersects the intersection of the shaft central axis and the shaft proximal end. The weight of the toe bar is about 15 percent to 25 percent of the total head weight and located more closely adjacent to the head toe than the head heel. Further the toe bar center line is about 2.75″ to 3.25″ from the shaft center line as measured horizontally along the head sole. The head has a balance point on a horizontal synchronized line at an elevation of normal impact with a ball.

Abstract: A drilling tool, for example a core barrel inner tube assembly, includes a latch body mounting latches for movement into a latch seat to removably retain the assembly adjacent to a drill string bit end and to impart rotary movement to the latch body as the drill string is rotated. A spindle subassembly is connected to the axial inner end of the latch body, to in turn, mount a vibrational subassembly for imparting axial reciprocal movement to a core receiving tube as the drill string is rotated to facilitate entry of core into the tube. The vibrational assembly converts rotary motion of the spindle subassembly to axial reciprocal movement of the core receiving tube while the core receiving tube is not being rotated but is moved axially inwardly over the core.
