Abstract: A hose coupler optimally configured for use with a liquid manure drag hose has a pair of hose coupler ends that are joined using a hose coupler having minimal protrusions and diameter. Each of the hose coupler ends is provided with a plurality of ribs and grooves. These ribs and grooves are arranged to mate with corresponding grooves and ribs formed in a collar. For each hose coupler end, a pair of collars are preferably used to secure a hose thereto. The ribs and grooves are preferably configured to secure the hose and distribute tension applied to the hose throughout the coupler end, while ensuring that the hose wall integrity is maintained. The resulting coupler is compatible with heavier drag hose, will not interfere with or harm the hose during winding and unreeling, and will produce less drag and be less likely to produce interference with obstacles in the field.

Abstract: A cam lock fitting having a rotating female portion which may include a safety lock which prevents separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharges. Rotation of the female portion is accomplished by placing a connecting collar on the rear of the female end portion so that the female portion rotates about the connecting collar. The safety lock mechanism operates by placing opposing notches in the end of the male portion so that when the cam levers are opened the male and female portions of the cam lock fitting initially only slightly separate allowing the operator to quickly reclose the cam lock fitting if it contains pressurized material. The rotating female portion easily aligns the cam lobes of the cam lever with the notches on the male coupling so that the male and female portions can be separated.

Abstract: A technique facilitates enhanced sealing capability in a space saving format when utilizing a plurality of uniquely constructed seals. As a result, the seals are useful in swivels and other types of structures to provide secure sealing between seal surfaces while reducing the overall seal area. Each seal comprises a body having a seal base combined with lips which may be activated when the activation fluid is supplied under pressure. In swivel applications, the seals may be constructed in a vertical orientation as axial face seals. The vertical orientation of the seals enables construction of the swivel with a reduced cross-section and thus a reduced hydraulic loading.

Abstract: A complete telemetry system and methods for downhole operations. The telemetry system includes an instrumented near-bit sub located below the Mud Motor and connected to the drill bit as well as a conventional MWD tool located above the mud motor. Parameters such as inclination of the borehole, the natural gamma ray of the formations, the electrical resistivity of the formations, and a range of mechanical drilling performance parameters are measured. Electromagnetic telemetry signals representing these measurements are transmitted uphole to a receiver associated with the conventional MWD tool located above the motor, and transmitted by this tool to the surface via mud pulse signals. The system is particularly useful for accurate control over the drilling of extended reach and horizontally drilled wells.

Abstract: A drill string components having a thread extending around a body. The leading end of the thread can have a configuration that resists jamming and cross-threading. In particular, the leading end of the thread can include a planar surface normal to the body. The leading end of the thread can provide an abrupt transition to full thread depth that helps reduce or eliminate cross-threading. The leading end of the thread can be oriented at an angle relative to the axis of the drill string component. When mating male and female threads are similarly structured, the mating threads slide together along an interface at the thread start face and are drawn into a fully thread-coupled condition. The thread starts may have full circumference mating with no jamming positions.
