Title: Method and apparatus providing personalized mailbox filters
Inventor: ROCHKIND MARK M
IPC: H04M3/50
Filed: 1997-06-25
Granted: 2002-08-06
Abstract: An  electronic  mailbox  filters  or  sorts  messages according to personalized or customized rules set by the owner  of  the  mailbox  through  the  use  of  address extensions.     The  addressee  will  assign  an  address extension to a prospective sender before the sender sends a message.   The sender may use this address extension when addressing and sending a message to the addressee. The addressee can also provide a specific sender with multiple address extensions so that the sender could send messages relating to particular topics or projects.   The addressee will maintain a look-up table of valid address extensions.     This  look-up  table  correlates  address extensions  with  particular  levels  of  priority.    The addressee  can  change  the  priority  associated  with particular   messages   by   reassigning   the   priority associated  the  corresponding  address  extension  in  the look-up table.  Thus, even if a sender continues to use a particular address extension in the sending address, the mailbox  may  no  longer  treat  such  messages  with  the priority level expected by the sender.

Abstract: A vertical blind control includes a single control mechanism for traversing the vanes, i.e. opening or closing the blind, and for rotating the vanes to change the amount of light admitted by the closed blind. The control mechanism includes a wand, which is used to slide and rotate a shaft carrying opposed bevel gears. One bevel gear is engageable with a mating gear system connected to a tilt rod for rotating the vanes. The other bevel gear is engageable with a drum carrying a cord for traversing the vanes to open or close the blind. The shaft is slidable within the mechanism so that only one of the bevel gears is engaged at any one time to effect the desired operation.

Abstract: In the present invention, seal air passes through a tube extending in a stationary blade from an outside shroud to an inside shroud, flows into a cavity to keep the pressure in the cavity high so as to seal the high-temperature combustion gas, and is discharged to a passage.  Part of cooling air flows into an air passage to cool the leading edge portion, passes through the peripheral portion of the inside shroud to cool the same, and is discharged to a passage.  The remaining cooling air flows into a passage, passes through a serpentine cooling flow path consisting of air passages having turbulators, and is discharged through air cooling holes formed at the trailing edge.  The cooling air passing through the passage at the leading edge portion cools the peripheral portion of the inside shroud as well as the leading edge portion of blade, by which the cooling efficiency is increased.

Granted: 2003-11-18
Abstract: A method for manufacturing a core plug from a core blank having an outer rim, a top surface and a bottom surface. The method comprises positioning the core blank into a stamping apparatus. Subsequently, a recess is stamped into the outer rim of the bottom surface of the core blank. Next, the bottom surface of the core blank is positioned in a blank accepting region of a second die member of a core die formation apparatus. The core blank is then propelled through an opening extending through the second die member, and, the outer rim is deformed inward and upward, thus forming the core plug. The deformation does not affect the recessed region of the resulting core plug. The invention additionally comprises a core plug manufactured by the foregoing method and a core die formation apparatus used in conjunction with the method.

Abstract: An optical switch operatively sensitive to a fluid pressure differential includes a housing having an open end, a fiber optic input line, a fiber optic output line, and a fluid-proof diaphragm sealingly engaged with the housing. The diaphragm is formed from a thin elastic material resiliently stretchable between first and second switching states and supports an optical barrier within the housing for blocking the propagation of an optical signal between the fiber optic lines when the diaphragm is in one switching state and for permitting the propagation of the signal between the fiber optic lines when the diaphragm is in the other one of the switching states. For a given housing and a given diaphragm, different optical barriers may be employed to achieve different switching thresholds. As well differing optical barriers may be used to make the switch either a normally "on" switch or a normally "off" switch. Apparatus for monitoring the level of a liquid may include a plurality of such switches.
