Title: Process of treating a stainless steel matrix
Inventor: OBALLA MICHAEL C
IPC: C23C8/02
Filed: 2001-08-16
Abstract: Heat resistant stainless steel may be treated in a low oxidizing atmosphere in a heat/soak-heat/soak sequence to deplete its surface of Ni and Cr which tend to catalyze coking of hydrocarbons in contact with the surface of the stainless steel, and enrich it with elements which are inert to coke formation. Parts made of stainless steel, such as furnace tubes or coils, treated in accordance with the present invention when used have a significantly reduced rate of catalytic coking.

IPC: G06T15/00
Filed: 1999-07-23
Abstract: A method and system for computer aided design (CAD) for designing geometric objects (30, 34). The present in-vention interpolates and/or blends (B1(u, v), B2(u, v)) between geometric objects (62) sufficiently fast so that real-time deformation of such objects occurs while deformation data is being input. Thus, a user designing obtains immediate feedback to input modi-fications without separately entering a command for performing deformation.  The present invention utilizes novel computational techniques for blending between geometric objects, wherein weighted sums of points on the geometric objects are used in deriving a new blended geometric object. The present invention is particularly useful for designing the shape of surfaces (S1, S2) and various design domains; additionally, providing efficient animation via repeatly modifying surfaces of an animated object.

Abstract: Certain events occurring throughout a microprocessor chip are monitored by a counter system (1) containing a number of digital electronic counters (3, 5, 7 & 9) consolidated at a single location on the processor chip. Those events are communicated to the counter system via electrical leads extending to those functional units in the processor responsible for signaling an event occurrence. Under program control, each counter can be selectively connected (11, 13, 15 & 17) to a selected one of the various functional event producing units. By means of selection logic (19, 21, 23 & 25) separate events originating from multiple functional units may be logically combined, whereby the event counted is a Boolean logic combination of multiple underlying events.

Abstract: To process the layout of graphical objects, elastic data structures are established for the graphical objects to define minimum and preferred sizes,  stretch properties and compression properties. One application of elastics i s with respect to text blocks where preferred width and compressibility of eac h text block is a function of the amount of text in the text block. Composite graphical objects include elastic properties computed from their components through add and max operations which are dependent on relative elasticities of the components. The positions of origins within graphical objects are define d by pairs of elastics in each of two dimensions. The default width or height preference of a graphic object can be overriden. Overriding elastics is an effective mechanism for altering the display characteristics of graphical objects while preserving certain display relationships. The elastics and dimensions of graphical objects are processed in a three pass layout negotiation. In the first pass, preferred sizes and elasticities of the graphical objects are computed along a first dimension. In a second pass, si ze values of the graphical objects along the first dimension are computed from the preferred sizes and elasticities, and preferred sizes and elasticities o f the graphical objects along a second dimension are computed based on the siz e values of the graphical objects along the first dimension. In a final pass, size values of the graphical objects along the second dimension are computed  from the preferred sizes and elasticities.

Abstract: A touch system includes a reference frame, and at least two cameras having fields of view that overlap within the reference frame. The position of an object relative to the reference frame is determined from captured images of the object based on triangulation. The fields of view of the at least two cameras are rotated with respect to the coordinate system of the reference frame to define offset angles. The touch system is calibrated by: capturing an image of the object using each the at least two cameras at at least one location within the reference frame; and for each location: determining the position of the object within each image, the position of the object within each image being represented by an angle .PHI., the angle being equal to the angle formed between an extremity of the field of view extending beyond the reference frame and a line extending from the camera that intersects the object within the image; and mathematically calculating the offset angles of the at least two cameras based on the angle determined for each image and the positions of the at least two cameras relative to the coordinate system assigned to the reference frame.

Abstract: A gasket for a pipe joint includes an annular gasket body which is symmetrical around an axial centerline and is therefore insensitive to axial orientation. The gasket is formed of a resilient material and includes a base adapted to sealingly engage an annular groove formed in one of the pipe segments to be joined. First and second protrusions run along the length of the gasket body and extend radially therefrom. The first and second projections are spaced apart symmetrically about the centerline. An annular bore, bisected by the center line, extends within the interior of the gasket body, and comprises a central region bridging first and second transversely spaced apart lobes.      It is particularly suited for sealing an annular space in a bell-and-spigot pipe joint and provides an increased surface contact area to compensate for defects in the sealing surfaces of the pipes.
