Abstract: A nailing plate for nailing to a wood member includes a sheet of metal having a plurality of elongate teeth extending from a face of the sheet. Each tooth includes a shank portion and a tip portion. The shank portion has two straight longitudinal sides extending from the face of the sheet to the tip portion so that the longitudinal sides are substantially free of any bends. The tip portion is defined by a curved end curving continuously between the two straight longitudinal sides such that the curved end is free of any substantially straight segments. Other features are disclosed.

Abstract: A weather resistant textile article comprising: a primary outer shell having an edge at least partially defining an opening for wearing the article; and a moisture wicking lining attached to at least the primary outer shell. In the preferred embodiment, the article includes a secondary outer shell attached to the primary outer shell. Also, in the preferred embodiment, the article includes a moisture permeable adhesive layer joining the shell and the lining.

Abstract: A reverse circulation drill rod of the dual tube type having a pin and box at opposite ends with a floating inner tube concentrically situated, the inner tube permitted longitudinal freedom of movement. A plurality of inwardly protruding radial directed lands adapted to encompass and align the inner tube are contained within each box and pin. Compression springs attached to the inner tube residing interiorly to the outer tube provide the longitudinal freedom of movement within limits. As the sections of drill rod are assembled vertically during operation, freedom of lengthwise movement by the inner tube allows stacking of the inner tubes in order that a seal be achieved between the square ends of each inner tube section. Compressed air or liquid is forced down the cylindrical space annulus formed between the outer tube and the inner tube, and drill bit grindings or rock fragments, together with the fluid, is brought to the ground surface in the conduit provided by the inner tube for simultaneous analysis.
