Provided, in one aspect, is a downhole magnetic debris removal apparatus. The downhole magnetic debris removal apparatus, in one aspect, includes a housing having a longitudinal axis, and a plurality of magnets arranged as one or more Halbach arrays of magnets coupled to the housing, the one or more Halbach arrays of magnets having a strong side and a weak side.

A measuring and guiding attachment for a chain saw includes a plurality of parts and is easily stored and deployed. The attachment has a swing arm assembly that is mounted on a front handle bar of the chain saw and a caliper plate attached to the distal end of that swing arm assembly. The swing arm assembly includes an end mortise and tenon joint and a telescoping joint, and the caliper plate is movably attached to the swing arm assembly so that the attachment has a plurality of degrees of freedom. A limit stop assembly is also included to permit further adjustment of the attachment.

A system for transporting a semi-trailer with a king pin and a wheel assembly on first and second drawn vehicles includes a stanchion on the first vehicle for releasably securing the trailer king pin. Ramp assemblies are provided on the vehicles and are extendable therebetween for loading and unloading the trailer. A pair of wheel cradles are independently and pivotally mounted to a butt plate box which in turn is adjustably mounted on a platform of the second vehicle. The wheel cradles receive the wheel assembly and have combination chocks and ramps pivotally mounted thereon.

Combined bellows pump and fluid dispensing container

A small diameter fluid-driven pump for subterranean fluid sampling, and including an elongated cylindrical body formed by a centrally disposed control valve block assembly and a pair of hollow motor piston chambers on opposite sides of the valve block and joined thereto. Within the centrally disposed control valve block assembly in axial alignment with the motor pistons are a spool pilot valve and a spool fluid distribution valve. The spool pilot valve is constructed to obviate stalling during its reciprocation under the impress of a power fluid directed thereto, and it functions to control the shifting of the distribution valve to which it is internally connected within the valve block assembly. The spool pilot valve includes a valve housing defining a large central piston chamber, a relatively small bore extending axially inwardly from one end of the valve housing, and into communication with the large central piston chamber, and a larger bore of smaller diameter than the central piston chamber extending axially into the opposite end of the valve housing into communication with the central piston chamber. A small piston is slidably positioned in the relatively small bore, a larger piston in the larger bore and a largest piston in the central piston chamber. A power fluid charging port communicates with the central piston chamber through the valve housing, and inlet and exhaust ports communicate with each of the bores. Sealing means on the largest piston in the central piston chamber allows power fluid to bleed from the power fluid charging port to opposite sides of the largest piston when this sealing means is directly aligned with the power fluid charging port.
