A subsurface tool comprising an elongated steel shaft having a soil penetrating lower end element and having a threaded upper end, a transverse elongated handle having a pair of ends for manual gripping thereof, and a central zone, an elongated isolator between the shaft upper end and the handle, the isolator being an electrically insulating, reinforced polymeric composite having an upper end ring portion encircling and molded to the handle at its central zone, and having a lower end socket, the...

A subsurface apparatus in the form a tractor is adapted for travel through a bore containing a moving fluid stream. The tractor comprises a body, a drive arrangement for moving the body in a desired direction, a member mounted on the body and adapted to be driven by the moving fluid, and a conversion arrangement for converting movement of the member to drive for the drive arrangement. The drive arrangement may include a contactless magnetic coupling and a harmonic drive.

A subsurface sampler including a cylindrical casing with portholes to provide access below ground to sample potentially hazardous substances without contaminating investigative probes that are inserted into the interior cavity of the casing. The sampler has an inner sleeve that seals the portholes on the casing during the insertion operation. After the casing is inserted into the ground, the inner sleeve is rotated such that the windows on the sleeve and casing line up exposing the soil to a var...

A subsurface filler comprising a pneumatically controlled scale, timer, lance descent and ascent mechanism, liquid fill mechanism, movable drip tray and exhaust mechanism. The filler may be used with different sizes of containers and with hazardous and noxious liquids.

A subsoil irrigation system comprising a flexible conduit with a longitudinal row of spaced outlet nozzles passing through the conduit and exteriorly protected by a flat having an edge secured to the conduit, a free edge with a bead, and wherein the conduit is formed on a slight curve so that when it is straightened in position underground the free edge of the flat will lie in intimate contact with the conduit to prevent the intrusion of foreign particulate matter in the nozzles.

A subsurface pump for a producing oil well, and the like, wherein a passageway is provided for directing a lubricant into the annulus between the working barrel and pump plunger for facilitating the reciprocation of the plunger.

Pieces of flat glass are cut to desired size without the necessity of grinding to size and polishing. Edges of the piece are cut in accordance with a procedure involving the use of a large-diameter scoring wheel at a greater-than-usual applied pressure, to produce a subsurface crack that is substantially free of serrations, followed by the application of a bending moment about the crack to propagate a fracture in the piece of glass. Light seaming of the top and bottom portions of the edges compl...

A method and system of delivering energy to material in which energy is converted to thermal energy in the material, and prior to significant therapeutic or other physiological change in a selected or target region of the material, results in a temperature rise which is maximum in a selected region of the material but which is insufficient to cause significant therapeutic or other physiological effect, the system for selective preheating of subsurface target regions of material such as human tis...

The subsurface signal transmitting apparatus (10) including an insulation coupler (11), a carrier device (12) for mounting the telemetry instrumentation (75), and a by-pass system for avoiding pressure build-up either above or below the apparatus. The insulation coupler (11) includes a housing member (13) having a central opening (16) defined by an interior surface (22) extending in the longitudinal direction and a mandrel member (14) having an exterior surface (32) spaced from the interior surf...
