摘要:
Latches including a housing, a rotary pawl, catch means for releasably holding the pawl in a closed configuration, and means for operating the catch means are disclosed. The pawl is pivotally attached to the housing and is rotationally movable between a closed or engaged configuration and an open or disengaged configuration. The pawl is provided with a torsion spring member that biases the pawl toward the open or disengaged configuration. In some embodiments the catch means includes a locking member. In other embodiments the catch means includes a pivotally movable trigger. The means for operating the catch means may be electrically powered.
摘要:
An electromechanical push to close latch has a pawl positioned for linear movement in a housing, with the pawl being biased to the outward extended position. An electric motor operates a cam to change the position of the pawl thereby retracting it into the housing. An electronic circuit board controls the operation of the electric motor under the direction of an outside control signal. The circuit board also senses the position of the pawl to stop the operation of the motor when the pawl is fully retracted. The pawl mounting can be reconfigured for the pawl to extend and thereby operate in a plurality of selectable directions.

Methods of the present invention allow a user to be enabled to create a metadata tag associated with a product on an ecommerce site. Using the metadata tag, a product category associated with the product may be dynamically created.
摘要:
A technique enables the efficient connection of communication lines in a well application by substantially reducing online rig assembly time. The technique reduces online time of the rig by sealably fastening a first connector of a downhole connection assembly to a segment of a communication line during offline assembly time to substantially reduce the online time requirements. The first connector is later connected to a corresponding second connector while the rig is online to complete the downhole connection assembly that joins communication line segments.

摘要:
An electronic coin validator for connection to a payphone chassis is described. The validator includes a coin passageway having at least one coin sensor, power circuitry for connection to payphone chassis power lines and connected to the coin sensor, a validator line balance circuit connected to the power circuitry, at least one coin signal line for connection to the payphone chassis, at least one coin value buffer, and a control means. The control means processes signals from the sensor to validate coins, adjusts the count in the coin value buffer when a coin is validated, and readjusts the count when corresponding coin credit signals are generated for transmission. The validator line balance circuit has an output for connection to the payphone chassis, and equalizes the loading on the telephone lines to minimize impedance fluctuations. Consequently, coins may be validated and accepted by the electronic coin validator as coin tones are being generated and transmitted by circuitry of the payphone chassis to a central office.
