Abstract: WINDOW COOLING AND PROTECTING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE     The invention provides an apparatus and method for protecting  a  window  of  a  housing,  the  window transmitting high intensity radiation therethrough for use in industrial processes.  Cooling liquid is supplied to a nozzle which produces a generally uniform sheet of cooling liquid which flows along the window and conducts heat from the window and restricts foreign matter ejected from the workpiece from contacting the window.   If the window is plane, the nozzle can be an elongated gap in a wall of a plenum chamber extending along the window.   A trough captures water passing along the window, and the water is recirculated back to the plenum chamber.   Preferably, to reduce liquid splashes, suction is applied to the trough and any entrained air is removed from the water prior to filtering and  cooling and returning the water to  the nozzle.  For an essentially continuous heating process of elongated workpieces, an elliptical sectioned chamber has a radiation source at one focus, and a target chamber at another focus, the workpiece passing centrally along the chamber.  The target chamber is a transparent cylindrical tube,  having a vortexing flow of liquid on an inside surface thereof to capture foreign matter ejected from the workpiece.  The chamber has a vortex generator at one end, and a liquid exhaust means at an opposite end.

Title: Method of seismic migration using a massively parallel computer
Inventor: HIGHNAM PETER T
IPC: G01V1/30
Filed: 1992-12-18
Abstract: A method for 3 dimensional, one pass migration of post stack seismic data is implemented on a massively parallel computer. The quality of the migration and speed of execution makes possible iterative 3D post stack depth migrations. The depth migration method computes in the frequency domain and downward continues one or more frequency planes through all depth levels of interest. For a single frequency, at mach depth level, the method extrapolates a shifted position for each x, y position by applying a filter for 2D convolution. A processing component is assigned to each subgrid of x, y spatial positions and the processing components operate concurrently in parallel to determine filter coefficients independently for each x, y spatial position and to extrapolate the x, y shifted positions. The filter coefficients are derived independently at each x, y position by storing a limited table of filter coefficients in local memory of each processing component.

Abstract: The routing paths between origin and destination nodes in a packet  switching network  are selected more efficiently by reducing the total number of links potentially  visited  by the   routing  algorithm.     The  path  selection technique  involves two phases,  the first   phase   for   principal   links identification,  and the  second phase for selection of the best point-to-point path in the network.    Principal  paths are minimum hop count paths with a transmission delay less than a  specified  threshold.    The  algorithm  limits the screening  of the  network links in the second phase to the principal links and  excludes  the  secondary  links.    The exploration  of  a  much  smaller number  of  links has the advantage  to  considerably  reduce  the  computation time required  for the path selection.   The fact the number of principal links is generally small compared with  the  total number  of  links  potentially explored, allows to limit the additional processing time necessary in case of unsuccessful attempt.
