Abstract: Abstract An  automatic  telephone  message device  for transmitting recorded messages to predetermined telephone numbers. The device is connected to the telephone jack and AC power source of the user's telephone, and is also connected to a standard tape recording system.  One or more messages are recorded by the user on the tape recorder.  The microprocessor controlled circuitry of this device provides memory space for convenient storage and modification of several telephone numbers.  This device is responsive  to  manual,  timed  automatic  or  remotely generated activation signals for transmitting the recorded message to parties answering at the specified telephone numbers.  An additional audible alarm may be set to sound at predetermined times, and if a manual switch is not closed within a specified time thereafter, the device calls the selected telephone numbers and transmits the recorded message.  In response to remote transmitter activation or lack of response to the audible alarm, a tone is transmitted in addition to the message indicating that the user is probably in the vicinity of the device. All specified numbers are redialed until the device senses that they have been answered, or until a specified maximum number of dialing attempts have been made.  The recorded message may be reviewed and the alarm activation time may be modified or deactivated by a party accessing the device from a remote telephone.

Abstract: Abstract A tubular member, to be a segment of the casing string, is provided with a polished bore at its upper end and a locking profile at its lower end.  The locking profile includes a bear-ing shoulder and internal left hand threads for coaction with a latching mechanism.  Another tubular member, to be a segment of the production tubing, has groups of circumferentially separated flutes to (1) maintain concentricity of the tubing segment, (2) provide axial flow passages between the segments, and (3) provide support for components of the tubing segment.          A tubular packing mandrel, mounted on flutes, carries external annular packing for sealing engagement with the polished bore.          The lower end of the packing mandrel defines an annular valve seat; and a tubular valve closure member, mounted in sliding, sealing relation on the tubing segment, has a coacting upward facing valve seat.  A valve spring urges closure of the valve closure member.  Lower flutes define a bearing shoulder for coaction with the casing shoulder to support the tubing string.    A latching mechanism includes circumferentially separated axially extending spring fingers carrying external threads for coacting ratcheting and threaded engagement with the profile threads.  When the tubing string is lowered to the support position provided by the bearing shoulders, the tubing segment is locked within the casing segment.

Abstract: Abstract Apparatus  for making  up underwater  fluid connections comprising first and second connector assemblies each com-prising at least one conduit connector member, the connector members of the two assemblies being matably connectable by movement of the assemblies toward each other.  A pair of levers carried by the first assembly are pivotable about a first axis transverse to the direction of movement in connecting the two assemblies, the two levers further being generally parallel and spaced apart along said first axis.  The levers have force transmitting arms engageable with the second assembly to urge it toward the first assembly, and are interconnected for joint pivotal movement.  The levers have a terminal position engaged with the second assembly when the connector members are con-nected, and lock bars carried by the first assembly retain the levers in the terminal position.  The levers, lock bars, and second assembly are interconnected in the terminal position such that attempted movement of the assemblies away from each other tightens the engagement between the lock bars and the levers.

Abstract: Abstract Described herein is a vapor phase adsorption separation process for removing and concentrating at least one organic molecular species such as ethanol present in a minor amount from a dilute aqueous mixture such as fermentation beer. Ethanol in the vapor phase is selectively adsorbed into a hydrophobic adsorbent mass consisting of a molecular sieve material such as silica-bonded F-silicalite which has a greater selectivity for ethanol than for water.  The vapor phase adsorption separation process is especially useful in providing concentrated ethanol from fermentation beer to supplement the world energy and chemical needs.
