Title: Enhanced capacity multiple-downcomer fractionation tray
Inventor: RESETARITS MICHAEL R
IPC: B01D3/14
Filed: 1994-09-19
Granted: 2005-09-13
Abstract: Vapor capacity of multiple downcomer type fractionation trays is increased by the provision of vapor directing slots in the tray deck, with the slots being oriented toward the closest downcomer to reduce froth height. The slots located in the relatively narrow deck area between downcomers are accordingly divided into two sets which point in opposite directions. Vertical baffles are provided above the downcomer inlets. The baffles preferably extend upward to slightly below the lower surface of the next higher tray, with the upper edge of the baffles being notched to accommodate the downcomers of this next higher tray.

Granted: 2001-08-28
Abstract: A disk-shaped optical storage medium for binary information, stored serially as a sequence of pits and lands along a spiral track in the form of pits and lands readable by means of a la-ser beam according to the principle of interference may be identified in a manner preventing confusing and unauthorized duplication in that a selected number of the total lands is formed in the optical reference surface as depressions which are shallow in comparison to the depth of the pits. This iden-tification feature of basically any form may be both so small that it can only be rendered visible by electron microscopic means and so large that it can be detected by the naked eye in diffused light.

Title: Padless touch sensor
Inventor: REPPER PIERRE
IPC: H03K17/96
Filed: 1997-04-15
Granted: 2001-06-26
Abstract: The padless touch sensor is used for detecting a touch at a sensing location onto a dielectric element by a user coupled to earth.  The sensor comprises a conductive plate attached under the dielectric element and in registry with the sensing location.  A  predetermined  potential  is  applied  on  the conductive plate.  Simultaneously, test pulses are produced into earth.  When the user touches the dielectric element at the sensing location, a potential variation in the conductive plate is produced during a test pulse due to a capacitive circuit formed between earth, the user and the sensor.  No deposition of conductive pads on the dielectric element or other special processes  are  required.  Foreign matter or objects  placed directly on top of the dielectric element will not erroneously produce a touch condition.
