Title: Interface for representing effects in a multilanguage optimizing compiler
Inventor: GROVE RICHARD BARRY
IPC: G06F9/45
Filed: 1992-02-18
Granted: 1992-08-28
Abstract: A compiler framework uses a generic "shell" or control and sequencing mechanism, and a generic back end (where the code generator is target-specific). The generic back end includes the functions of optimization, register and memory allocation, and code generation. The shell may be executed on various host computers, and the code generation function of the back end may be targeted for any of a number of computer architectures. A front end is tailored for each different source language, such as Cobol, Fortran, Pascal, C, C + +, Ada, etc. The front end scans and parses the source code molecules, and generates from them an intermediate language ("IL") representation of the programs expressed in the source code. This IL is constructed to represent any of the sou rce code languages in a universal manner, so the interface between the front end and back end is of a standard format. and need n ot be rewritten for each language-specific front end. The IL representation generated by the front end is based upon a tuple as t he elemental unit, where each tuple represents a single operation to be performed, such as a load, a store, an add, a label, a br anch, etc. A data structure is created by the front end for each tuple, with fields for various necessary information. One feature of th e invention is a mechanism for representing effects and dependencies in the interface between front end and back end; a tuple has an effect if it writes to memory, and has a dependency if it reads from a location which some other node may write to. A mechanism inde pendent of source language is provided for describing the effects of program execution. Another feature is the use in t he optimization part of the compiler of a method for analyzing induction variables, where the improvement is to use the side effe cts sets used to construct IDEF sets. Another feature is a mechanism for "folding constants" (referred to as K-folding or a KFOLD rout ine), included as one of the optimizations. A further feature is the type definition mechanism, referred to as the TD module , which provides mechanisms used by the front end and the compiler of the back end in constructing program type information to be incorporated in an object module for use by a linker or debugger. Another feature is a method for doing code generation usin g code templates in a multipass manner.

Title: Slick line casing and tubing joint locator apparatus and associated methods
Inventor: KILGORE MARION D
IPC: E21B47/09
Filed: 1994-10-25
Granted: 2003-01-14
Abstract: A detector structure is used to sense and log the joints in a downhole jointed tubular structure, such as a well bore casing or production tubing, in a subterranean well. The detector is moved through the jointed tubular structure on an elongated positioning member, representatively a slick line, through a series of joints to be logged. As the detector passes through each joint it electromagnetically senses the joint and responsively generates an electric output signal. The output signal is used to momentarily cause a drag structure portion of the detector, in cooperation with the interior side surface of the tubular structure, to momentarily create a detectable tension change in the elongated positioning member. Alternatively, a pyrotechnic or compressed gas device may be used to create the detectable changes in response to the generation of the electrical output signals. These tension changes, which may be either tension increases or tension decreases, serve as mechanical output signals transmitted upwardly through the positioning member, and may be plotted on a strip chart recorder at the surface to record the joint locations and correlate them to the lowered depth odometer readings of the detection system.      Using this joint detection apparatus, correlative joint logging procedures may be carried out for tool setting purposes without the necessity of utilizing an electrical conductor line.

Abstract: There is described a method and apparatus for detection and thickness evaluation of a buildup of a solid, e.g. ice, or liquid on a solid surface, such as ice on a body of an aircraft.      The apparatus comprises a source of a narrow beam of radiation and a means for remote evaluation of the size of a luminous area created on the solid surface by the beam.      The method of the invention involves measuring the size of the luminous area and determining the thickness of any built-up layer, if sufficiently transparent, using a formula which uses the dependency of the size of the luminous are on the thickness of the layer and the refraction index of the medium. Differentiation between ice and a liquid is possible by evaluating regularity of illumination of the luminous area.
