Title: Inclined separation tank
Inventor: WALKER CLARK FAULKNER
IPC: B01D17/00
Filed: 1997-04-09
Granted: 2002-01-29
Abstract: A vessel designed to separate out clean water from produced oil is disclosed. Conventional free water knockout vessels (FWKO) are normally disposed horizontally, and have a large diameter. The large diameter maximizes the distances between the oil/water interface and the exit points on the vessel for the water and the emulsion. The larger the vertical distance from the oil/water interface, the greater the chance that the oil and water can be agitated by slugs of gas and fluids. Tilting the vessel and reducing the diameter minimizes the distance the fluid has to travel to reach the top and bottom walls of the vessel, maximizes the distances from the oil/water interface, utilizes more fluid space in the vessel, reduces agitation caused by gas slugs, and forces the water to travel a longer distance which provides more separation time.

Title: Apparatus for automatic layout and cutting corner lines in stone
Inventor: CETRANGOLO DOLIVIO L
IPC: B27B31/06
Filed: 1998-08-25
Granted: 2001-12-11
Abstract: An apparatus or machine is disclosed for automatic establishing and cutting the corner lines in a piece of stone. The machine includes two pairs of saw blades, each pair disposed on opposite sides of the stone. The saw blades are adjustable in two directions with respect to each other to properly locate the saw blades with respect to the four corners of the stone. Laser light sources are positioned to provide light beams down onto the piece of stone at the precise location of the outer edge of the saw blade. The laser light sources assist the machine operator in properly positioning the stone with respect to the saw blades. Once the stone is properly located, the saw blades are moved into cutting engagement with the stone. After the four corner lines of the stone have been cut, these corner lines precisely establish the dimensions of the rectangles on the top and bottom stone surfaces, and the four vertical corner lines connecting the two rectangles.

Inventor: EATON JAMES RUSSELL
IPC: F16H25/24
Filed: 1997-01-29
Granted: 2002-08-27
Abstract: The actuator includes a housing (12) and a gear nut (64) within the housing (12). A leadscrew (78) on which the gear nut (64) is threaded traverses the housing (12). As the leadscrew (78) moves axially, the gear nut (64) rotates.  To prevent misalignment between the gear nut (64) and leadscrew (78), the gear nut's outer walls (74 and 76) and bearing surfaces (30 and 46) within the housing (12) permit the gear nut's axis of rotation to pivot in any direction along with any pivoting of the leadscrew (78), while allowing the gear nut (64) to rotate about the leadscrew (78). Therefore, if the leadscrew (78) is not aligned with the housing (12), the leadscrew will pivot the gear nut (64) so that the gear nut (64) remains aligned with the leadscrew (78) and movement of the leadscrew (78) can continue.

Granted: 2005-10-11
Abstract: A system and method to detect a call trigger during a call without requiring a service platform to remain connected to the call. A first communication device (106) transmits a call having call signaling and user communications. A signaling processor (112) receives the call signaling from the first communication device and selects a connection to a second communication device (108). An interworking unit (114) receives the user communications from the first communication device and converts the user communications from a time division multiplex format to asynchronous transfer mode cells that identify a selected connection to the second communication device. The interworking unit detects a call trigger in the user communications. The interworking unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the interworking unit to transport the user communications to asynchronous transfer mode cells that identify the selected connection to the thrid communication device (110) and transports the user communications to the third communicati on device.

Abstract: A moving vector between frame is detected by a moving vector detecting unit and the display positions of the subfields of pixels in a block are corrected using a moving picture correcting unit in accordance with the detection values of the moving vector. The picture quality is not deteriorated when corrected. In order not to output an erroneous moving vector, a lowest correlation factor S1 detected by a lowest correlation factor detecting unit (20) is multiplied by 1.5, the correlation factors not larger than S1 are substituted by S2 (S2<=S1), and, among a plurality of blocks with the correlation factors S2, the block closest to the origin is used as the starting point of the moving vector.     In order not to input an erroneous moving vector to the moving picture correcting unit, a moving vector is determined by the majority decision of the moving vectors of surrounding blocks. The movement of a line has first priority (Fig. 13).
