Title: Valves for pressurized containers
Inventor: MOHN CHRISTOPHER DANDRIDGE
IPC: F16K1/30
Filed: 1996-01-19
Abstract: A non-refillable valve for a pressurized container which includes a unidirectional stepped valve housing within which a freestanding blocking element is housed.  The blocking element is preferably a reversible, symmetrical check that integrally includes stop means for preventing the return of said blocking element to an initial location after it has been moved to a final location that activates the one way characteristic feature of a non-refillable valve (where activation is designed to take place after initially charging of the container).  Further aspects of the invention relate to blocking elements (checks) per se which are suitable for use in non-refillable valves.  In particular, blocking elements that are easy to manufacture and install, blocking elements that possess a degree of rigidity which enhances the check's ability to function as a freestanding element once inserted into a valve housing, and blocking elements which inherently reduce the risk of false check engagement during the valve assembly process, are all contemplated by the present invention.  Other aspects of the invention relate to dual purpose manufacturing processes that use a single basic valve design to enable both refillable and non-refillable valves to be manufactured; and relate to products of the aforementioned processes.

Title: System for archiving voice mail messages
Inventor: JONES SCOTT A
IPC: H04M3/533
Filed: 1996-03-05
Abstract: An archival system for voice mail messages includes recording devices, such as cassette recorders, compact disc recorders and DAT recorders. The archival system may be directly connected to one or more voice mail systems, or connectable via the public switched telephone network, so that the archival system can serve several voice mail systems. Voice mail messages identified by users to be archived are stored in a transfer queue in a voice mail system. The voice mail system performs an outdialing operation to connect to the archival system and transmits the voice mail messages, together with message identifying information, such as preferred storage medium and an optional header identifying the message, to a storage queue in the archival system. The archival system instructs an operator to mount a tape or other storage medium in a selected device and then records the voice mail messages on a removable storage medium, such as audio tape. The resulting tape is then sent to the user and the original voice mail messages may be deleted.

IPC: H04M3/523
Filed: 1994-09-16
Abstract: A telephone system provides dynamic inbound/outbound call management for a telemarketing campaign to automatically initiate outbound telephone calls for outbound agents, with outbound agents redesignated as inbound agents to answer inbound calls as needed according to at least one threshold of number or duration of waiting calls or number or duration of waiting inbound agents. Each agent's work area (35) includes a telephone station (40) having a display (30) and an input device (32). The telephone stations (40) are coupled to a server (20) via a network, and the telephone system includes appointment and calendar functions with pop-up menus.  The server (20) is also coupled to an automatic dialer (50) and to a private branch exchange (60). When the server (20) assigns an outbound call to an outbound agent, the server sends information about the party called to the outbound agent's telephone station for display simultaneous with connecting the called party to the outbound agent.  The telephone system allows each agent to control all telephone functions through the telephone station using the display (30) and input device (32). Each agent may dial and control additional calls using the input device (32), including central office calls, intercom calls and paging. As each outbound call is initiated or completed, system parameters are adjusted to maintain a predetermined minimum number of busy outbound agents. The adjustments also maintain the percentage of unattended outbound calls for which no outbound agent is available.

Title: Anti-glare eye exerciser
Inventor: JOHNSON BERTHULD T
IPC: A61H5/00
Filed: 1996-10-22
Abstract: This invention relates to exercising the eyes.  I had extreme difficulty with glare when facing city lights, car lights and sunshine.  I wore dark sunglasses during the day, but impractical for night driving; the road ahead was obscured.  I experienced headaches as well.  I had my eyes tested and wore glasses, but the glare problem remained.         I read that the cause of glare can be a lack of blood supply to the eyes which allows one image after another to pile up within the eye and cause glare.  And it explained, the eye muscles, if exercised, help the blood supply to clear the fouled imagery.  The suggestion was to lie on one's back and look at a corner of the room and then another in rotation.         I tried this but it was difficult to do and with no noticeable improvement.  I devised this invention as herein described, using it for ten or fifteen minutes a day over two weeks, and the glare of lights was minimized, so that I did not need sunglasses.  I found the exercises very relaxing as well.
