摘要:
A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valve if the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

A frameless inflatable pontoon boat in which the pontoons and connecting section have a generally flat top and a generally flat bottom. Sufficient rigidity is achieved in the inflatable connecting section and the pontoon by the use of internal thread connections between the top surface and the bottom surface. The internal thread connections confine the inflated shape of the pontoons and connecting section to a flat shape.

The invention is a protective cover for a buckle, for protecting a vehicle from the buckle, which may be used with a strap to secure loads such as kayaks, rafts, and canoes to the vehicle roof. The buckle and its attached strap can be inserted into the protective cover, and can later be removed from the protective strap if desired. The release lever of the buckle is covered by the protective cover, and is depressed by pressing down on a portion of the protective cover.

This application describes a system for contraband and weapons detection. The system comprises a coplanar sensor array, electronic drive circuitry, a data acquisition circuit, a video frame grabber, a video camera, and a computer control unit with a control module installed. Properly constructed and aligned, the system allows for the detection of very small magnetic moments, which surround ferromagnetic materials. This ferromagnetic detection allows users to screen personnel for contraband electronic devices and concealed weapons.

A loader device is disclosed for moving cargo to and from a vehicle roof. The loader, attached to trailers or other vehicles includes a channel, a carriage and a winch. The carriage, powered by the winch, travels up the channel to raise cargo to the vehicle roof. The carriage travels down the channel to lower cargo from the vehicle roof. Rungs attached to the channel form a ladder for human access to the vehicle roof. When not in use, the carriage folds to assume a smaller profile.

A recreational vehicle is disclosed, comprising a plurality of wheels configured to enable the recreational vehicle to roll along the ground, an interior living space enclosed by a plurality of walls, and a generally U-shaped seating area. In some embodiments, the generally U-shaped seating area may comprise two side couches and an interior couch that utilizes a lower mattress as a seat cushion. An exterior couch may face opposite the interior couch and also utilize the lower mattress as a seat cushion. In some embodiments, the recreational vehicle also comprises tracks for elevating the lower mattress and an upper mattress, and elevated table mounts attached to the bottom of the upper mattress that may be used to store one or more table tops below the upper mattress.
摘要:
A linear lost motion mechanism is located within a tubular handle of a machine, such as a concrete finishing machine. The linear lost motion mechanism includes a pitch block configured to selectively frictionally lock with the tubular handle or a component attached to the tubular handle using a biasing spring. The linear lost motion mechanism can perform a number of functions, such as controlling a blade pitch adjustment system of a concrete finishing machine.
摘要:
A locking device for multiple-section telescoping tubes wherein a smaller tube is telescopically retractable into or extensible from within a larger tube includes a pair of opposing blocks, disposed within the telescoping tubes, one block being attached to the smaller tube, the other block being configured to move laterally with respect to the first block when the blocks are moved longitudinally with respect to each other. Depending on the direction of longitudinal movement of the blocks, one block may be caused to bear against an inner side of the larger tube to resist retraction of the smaller tube, or the blocks may be allowed to move away from the inner side of the larger tube to allow free sliding extension of the smaller tube. The device also includes means for selectively longitudinally moving one of the blocks with respect to the other, so as to allow free sliding retraction of the smaller tube, when desired.
