Title: Continuous method for separating a c<sb>4</sb> cut.
Inventor: HEIDA BERND
IPC: C07C7/08
Filed: 2003-07-22
Abstract: The invention relates to a continuous method for separating a C4 cut (C4) by means of extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK). A separating wall (TW), forming a first partial region (A), a second partial region (B) and a lower common column region (C), is arranged in the longitudinal direction of the extractive distillation column (EDK). According to said method, a head flow (C4H10) comprising butane is separated from the first partial region (A), a head flow (C4H8) comprising butene is separated from the second partial region (B), and a flow (C4H6) comprising the hydrocarbons from the C4 cut is separated from the lower common column region (C), said hydrocarbons dissolving more easily in the selective solvent (LM) than the butane and the butene.

Title: Method and system for displaying and managing security information.
Inventor: HITCHCOCK DANIEL W
IPC: G06F21/62
Filed: 2005-03-23
Abstract: A method and system for managing security information for a domain of computer systems is provided. The security system displays security information for a selected security object, such as a user or a computer system. The security system initially retrieves security information that includes security specifications that each has the identification of an entity, a resource, and an access right for the selected security object. The security system then displays an identification of the entity and the resource along with the access right for each security specification. When the security information is stored in a security store (i.e., the main security store) by resource and, for each resource, the entities that have access rights to that resource, the security system may use an auxiliary security store to facilitate the retrieval of the security information.

Title: Handoff in dormant mode in a packet data network.
Inventor: ARUNGUNDRAM C MAHENDRAN
IPC: H04Q1/00
Filed: 2003-10-09
Abstract: Mobile unassisted dormant handoff in a wireless communication system supporting packet data communications. While in a dormant mode, a mobile node may change packet zones, wherein different packet zones are serviced by at least one different infrastructure element, without identifying the change to the system. The change in packet zone does not necessarily trigger establishment of a communication path for the mobile node until there is packet data ready for communication. In one embodiment, mobile assistance is adapted to the system, and is disabled at the mobile node by an indication in a system parameter message transmitted by the system and received by the mobile node.

Title: Pound-in glide for an article of furniture.
Inventor: HORNBERGER TIMOTHY G
IPC: A47C7/62
Filed: 2004-04-02
Abstract: An article of furniture (22) having an opening (62) is configured with a support (20) operable to serve as a glide and as a floor surface protector. The support includes a body (40) having a boss (45) with a plurality of collapsible mounting boss sections (65). The boss sections define an axial passage (80, 90) therebetween and extending through the body. When inserted into the opening in the article of furniture, the edge defining the opening moves the boss sections radially inward relative to the edge of the opening toward a collapsed condition. The support further includes a wedge configured to be driven by an applied force into the passage of the body. The driven wedge is configured to move the boss sections apart against the edge of the opening to secure the body member to the article of furniture.

Title: System bridge and timeclock for rf controlled lighting systems.
Inventor: KRUSE GLEN ANDREW
IPC: G05B19/418
Filed: 2004-06-09
Abstract: A method for operatively interconnecting a first and second lighting control subnet is disclosed. In the method, a link claim is transmitted to the first and second lighting control subnets from a bridge. The link claim directs the first and second lighting control subnets to wait for a lighting control command, which is transmitted to the lighting control command to the first lighting-control subnet. A random wait time is assigned to the first lighting control subnet and a maximum random wait time is assigned to the second lighting control subnet. Finally, an acknowledgement is received from the first lighting control subnet.

Title: Adaptive fuel control for an internal combustion engine.
Inventor: LACY GERALD EDWARD
IPC: F02D41/22
Filed: 2004-05-20
Abstract: An adaptive fuel limit function (52) for protecting an internal combustion engine. The adaptive fuel limit function is a learning function responsive to trends in an engine performance parameter such as compensated fuel consumption per unit of power produced (62). The engine performance parameter is processed through a low pass filter (64) to allow changes in a fuel limit signal (54) in response to gradual changes in the fuel demand, such as may be due to wear in the engine, while blocking changes in the fuel limit signal in response to sudden changes in the fuel demand, such as may be due to a cylinder failure. The difference between the input and the output of the low pass filter may be processed to identify a failure level (88) for providing an alarm function distinct from the learning function.

Title: Integral method and system useful for treating cooling tower water and processes for removing silica from water.
Inventor: ALCOCER JUAN JORGE DIAZ GONZALEZ
IPC: C02F1/00
Filed: 2006-06-21
Abstract: The present invention refers to an integral system for treating cooling tower water and further processes involving inverse osmosis rejection, regeneration of demineralising systems in anionic units, aircraft waste waters, and waste water in general, where pollutants such as silica, magnesium and calcium hardness, suspended solids, organic matter and microorganisms, heavy metals, detergents, and arsenic are to be removed or reduced from water, thereby improving the quality thereof and allowing the same to be reused in different industrial processes, thus generating water and chemical product savings. The present system is characterised in that the water to be treated is passed through an electrochemical cell having aluminum, iron or any other metal plates, where an electric current is applied at an amperage suitable for generating a current density optimum for providing aluminum required to form aluminum, iron or other metal hydroxide. Said hydroxide is reacted with water pollutants s o as to form a sludge which would be subsequently separated from water, thus allowing water to be reused. The inventive system also includes filtration and ozonisation processes for providing quality water so as to be reused in cooling towers, industrial processes, general services, irrigation of green areas and further uses.

IPC: H04N3/30
Filed: 1991-03-22
Abstract: ADJUSTMENT AND MAINTENANCE OF A PHASE RELATIONSHIP BETWEEN A VIDEO SIGNAL ( ON 11) AND A SCAN SYNCHRONIZING SIGNAL (ON 67) TO ASSURE PROPER HORIZONTAL CENTERING IS PROVIDED IN A HORIZONTAL DEFLECTION SYSTEM (40). A FIRST OHASE LOCKED LOOP GENERATES A FIRST TIMING SIGNAL (ON 17) AT A FIRST FREQUENCY, SYNCHRONOUSLY WITH A HORIZONTAL SYNCHRONIZING COMPONENT IN A VIDEO SIGNAL. A PRESETTABLE COUNTING CIRCUIT (IN 56) OPERATES SYNCHRONOUSLY WITH THE FIRST TIMING SIGNAL FOR DIVIDING A CLOCK SIGNAL TO GENERATE A SECOND TIMING SIGNAL (ON 61) AT A SECOND FREQUENCY. A SECOND PHASE LOCKED LOOP (62) GENERATES A SCAN SYNCHRONIZING SIGNAL (ON 67) FROM THE SECOND TIMING SIGNAL. A MICROPROCESSOR (74) MAY SUPPLY DIFFERENT NUMBERS TO A REGISTER (IN 56), THE OUTPUT OF THE REGISTER BEING COUPLED TO THE PRESETTABLE COUNTING CIRCUIT. DIFFERENT NUMBERS (FROM 74) CHANGE THE RELATIVE PHASE BETWEEN THE FIRST AND SECOND TIMING SIGNALS BY INCREMENTAL STEPS. THE MICROPROCESSOR (74) MONITORS A VIDEO SOURCE SELECTION SWITCH TO GATE ONE OF ALTERNATIVE VIDEO SOURCES AS A VIDEO AND SYNCHRONIZING SIGNAL OUTPUT AND ADJUSTS THE RELATIVE PHASE BETWEEN THE HORIZONTAL SYNCHRONIZING COMPONENT OF THE SELECTED VIDEO SOURCE AND A SYNCHRONOUS TIMING SIGNAL BY A FACTOR APPROPRIATE FOR THE SELECTED VIDEO SOURCE. A MANUALLY OPERABLE CIRCUIT (72) MAY BE COUPLED IN A FEEDBACK PATH OF THE SECOND PHASE LOCKED LOOP (62) FOR ADJUSTING THE RELATIVE PHASE BETWEEN THE SECOND TIMING SIGNAL (ON 61) AND THE SCAN SYNCHRONIZING SIGNAL (ON 67), OVER A RANGE CORRESPONDING TO AN INCREMENTAL STEP.(FIG. 1)
