Title: Dual-member pipe joint for a dual member drill string
Inventor: DEKEN ARTHUR D
IPC: E21B7/00
Filed: 1997-02-12
Abstract: A dual-member pipe joint (24) having an outer member (26) and an inner member (28) which is disposed coaxially within the outer member (26). Both the outer member (26) and the inner member (28) have a pin end and a box end. The pin end of the outer member is threadable to the box end of another outer member. The pin end (94) of the inner member (28) is geometrically shaped. The box end (96) of the inner member nonthreadably receives the pin end (94) of another inner member in "slip-fit" connection. "Slip-fit" means the pin end of the inner member slides into the box end (96) of a like inner member and forms a connection that is capable of transmitting torque. The pipe joint may be connected to a drill string in a single action with just one connection. This dual-member pipe joint reduces boring time as compared to boring with conventional dual-member pipe joints, in which both the inner and outer members are threadably connected and thus require two pipe connections. This dual-member pipe joint is usable as a system of pipe, and as part of a boring machine.

Title: Compressor ball valve
Inventor: KOSCO JOHN JR
IPC: F04C29/12
Filed: 1997-10-21
Abstract: In a refrigerant compressor, a discharge valve assembly which reduces reexpansion volume. The present invention provides a discharge valve assembly for reciprocating, rotary, and scroll types of compressors, and includes a spherical valve member that engages and penetrates a discharge port provided on a compressor cylinder head, valve plate or scroll plate. The discharge port is formed in the cylinder head or scroll plate and is dimensioned such that the spherical member penetrates and substantially fills the discharge port. The reexpansion volume within the discharge port is thereby reduced. To maintain engagement of the spherical member with the discharge port, an elastically deformable arm having an aperture is positioned to hold the spherical member in the discharge port. The arm is elastically deformable to allow the spherical valve member to move out of engagement with the discharge port during the compression phase of the compressor. To prevent the spherical member from being discharged along with the compressed refrigerant, a rigid stop plate is disposed adjacent the deformable arm to engage the spherical member during the compression phase and thereby limit the movement of the spherical valve member.

Inventor: WILSON CAMERON A
IPC: F15B9/14
Filed: 1997-11-18
Abstract: The invention relates to a hydraulically operated variable rate rotational drive. A rotational drive rate is provided to a hydraulic motor by rotational input from an electric motor at a controlled rate. The electric motor rotates a rotary valve which opens the hydraulic connection to the hydraulic power source. Hydraulic fluid rotates the motor closing the hydraulic connection until the next rotation from the electric motor. This drive incorporates a torque generator, commonly available as used for incremental rotational drive such as power steering. Continuous hydraulic rotational drive from the motor accordingly matches the continuous input rate from the electric motor. The drive is particularly suited for controlling metering rates of rotational meters without the need for gearing. The rate is advantageously variable while in operation, saving significant time in metered seeding or fertilizing operations.
