| 23 | Geophone keyway tee protective casing | US10054254 | 2002-01-22 | US20030139090A1 | 2003-07-24 | Dennis L. Mudge |
| A protective casing for a three-way electrical connection comprises a cover and two lower pieces. Each lower piece preferably includes a protruding key and a key slot. The two lower pieces mate with one another with the protruding key of each lower piece engaging the key slot of the other lower piece. The keys and slots generally extend a length of the lower pieces and thus mating the lower pieces together includes engaging the keys and slots and sliding one lower piece along an axis relative to the other lower piece. Preferably, the lower pieces are substantially identical. In contrast to conventional tee connection casings, the lower pieces of the preferred embodiment can be mated together without disconnecting any conductors from the three-way electrical connection. Similarly, the protective casing can be removed and replaced with a new casing without disconnecting any electrical connections. | ||||||
| 24 | Remote electrical plug ejector | US09571129 | 2000-05-15 | US06540533B1 | 2003-04-01 | James W. Schreiber |
| A plug ejector for ejecting an electrical plug from an electrical power supply socket comprises an electronic device having a controller that monitors and senses electrical power supply characteristics and a solenoid, which operates an ejector member to separate the plug from the socket when predetermined sequence in rapid changes in electrical power supply characteristics are sensed. The plug ejector can be incorporated into an electrical appliance or extension power cord electrical plug, which plugs into and is ejected from a conventional power supply socket. It can also be mounted in an adaptor, which receives an appliance or extension cord plug and ejects the adapter from a conventional power supply socket. It can also be incorporated into a module, which is semi-permanently plugged into a conventional power supply socket or incorporated into a wall or other power supply socket. Upon rapid cycling of the appliance's On/Off switch, the solenoid projects the ejector to eject the plug and thus free the appliance or extension power cord from the power supply socket. The plug ejector may incorporate a GFCI protector. | ||||||
| 25 | Cable computer termination connector and sealing method | US332737 | 1999-06-14 | US6139354A | 2000-10-31 | Blaine L. Broussard |
| An improved termination connector for seismic cable, the improvement including a reduced rigid length and improved flexibility by making connector to cable conductor splice connection within the bend restrictor, further reducing failure due to lateral stress through the use of a split collar and sleeve arrangement for connecting the connector's rotatable nut assembly to the connector body. The instant connector improves pin to cable makeup with improved pressure compensation splice connection process. | ||||||
| 26 | Female socket assembly for electrical connector | US35415 | 1998-03-05 | US6102751A | 2000-08-15 | Timothy D. Becker |
| A removable socket assembly (36, 44) for an electrical connector (10, 18) in a take-out assembly for a seismic cable (11). The socket assembly (36, 44) has a receptacle (50) receiving a socket (52) in a threaded relation. Base (68) of socket (52) has a bore (82) of a hexagonal cross section and a tool (90) of a hexagonal cross section is received within bore (82) in a mating relation for removal and replacement of socket (52) in the event of malfunctioning. | ||||||
| 27 | Repairable electrical geophysical connector | US39097 | 1998-03-13 | US5980317A | 1999-11-09 | William O. McNeel |
| An electrical geophysical connector comprising an outer housing, a first connection member and a second connection member. First and second coacting electrical contacts are positioned in the first and second members, respectively. The first member includes a rigid outer shell and a resilient inner core bonded to the first electrical contacts. The first ends of the first contacts are positioned in cavities located in one end of the inner core and resilient seal rings are formed about the cavities for engaging and sealing the coacting engagement of the first and second contacts. A dust cap is rotatably mounted with a 360.degree. rotation to the housing and the exterior of the housing is tri-lobed in cross section for ease of gripping. | ||||||
| 28 | Two-piece universal cable-connector adapter | US654234 | 1996-05-28 | US5692918A | 1997-12-02 | A C Hill |

| 29 | Cable-fixed takeout | US243216 | 1994-05-16 | US5417592A | 1995-05-23 | Gregory W. West |
| A pigtail-type takeout on a seismic cable including a molded elastomer Y-body, a pigtail and a multi-contact connector for connecting the end of a geophone string to the cable. The connector body includes a longitudinally split inner tubular portion that is fitted around the cable, and tie wraps are used to encircle and hold the tubular portion tightly around the cable to firmly mount the connector body thereon. | ||||||
| 30 | Positively released seismic cable connector | US944305 | 1992-09-14 | US5297974A | 1994-03-29 | Don L. Fussell |
| In accordance with an illustrative embodiment of the present invention, an electrical connector assembly to connect the end of a seismic cable to a data acquisition unit includes a body member having a plurality of sockets in one end which react with pins on a companion receptacle. A tubular shell which is rotatably mounted on the body member has threads that make up with threads on the receptacle, and a drive ring which engages a shoulder on the body member to force the sockets onto the pins as thread make-up takes place. As the threads are released, the drive ring moves back into engagement with an opposed shoulder on the body member to positively separate the sockets and pins. | ||||||
