Title: Prosthesis of female mamma and the method of producing thereof
Inventor: VODNANSKY JIRI
IPC: A61F2/12
Filed: 1986-05-21
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE:            A prosthesis  of the  female mamma comprises  a spongy hydrophilic polymeric material (advantageously based on methacrylate or acrylate) surrounded by a surface formed from a layer of homogeneous  film having a similar composition to the spongy hydrophilic polymeric material. This film continuously passes into the spongy structure and is connected with it by chemical bonds.  The thickness of the homogeneous film may be controlled and is advantageously less than 0.5 mm.  A method for producing this prosthesis of the female mamma is by polymerization of a monomer mixture for preparation of the spongy polymer in an open mold in such a way, that a film from a soluble polymer based on methacrylate or acrylate is formed in the mold, before its charging with the monomer mixture.  This is done by casting the mold with a solution of the soluble polymer.  Then, after removing any solvent, the mold is charged with the monomer mixture for preparation of the spongy polymer and the mixture is allowed to polymerize in the presence of oxygen, advantageously in air.

Title: Method and apparatus for text analysis
Inventor: KUCERA HENRY
IPC: G06F17/27
Filed: 1987-06-05
Granted: 1992-02-11
Abstract: ABSTRACT          An electronic text analyzer operates on an ordered block of digitally coded text by analyzing sequential strings thereof to determine paragraph and sentence boundaries.  Each string is broken down into component words.  Possible abbreviations are identified and checked against a table of common abbreviations to identify abbreviations which cannot end a sentence.  End punctuation and the following string are analyzed to identify the terminal word of a sentence.  When sentence boundaries have been determined, the text may be further processed by a grammar checker, a readability analyzer, or other higher-level text processing system.         A preferred embodiment includes a readability analyzer having a syllable counter for determining the number of syllables in each word. The system includes a modified common-word table having an empirical syllable-count field.  A checker first determines if a word is in the table and, if so, returns its syllable count.  An exception table identifies words not conforming to a syllable counting algorithm.  Each word not in the common-word or exception tables is modified, and the modified word is processed to derive its syllable count.  In a preferred embodiment, tallies are kept of words per sentence, syllable count, sentences per paragraph, and similar data, and readability scores based on the tallies are displayed.

Title: Pipe line welding improvement

Granted: 1993-11-09
Abstract: "PIPE LINE WELDING IMPROVEMENT"                 ABSTRACT OF THE DISCLOSURE         A process is provided for heat treating an annular martensitic heat-affected zone.   The heat-affected zone is commonly created in the outer segment of a pipeline wall as a result of applying a circumferential fillet weld to the pipe. The embrittled zone creates a weakness in the pipe wall and it is therefore desirable to heat treat it.   The heat-treating process is carried out in connection with a situation where the pipeline has an open end located close to the weld and a plug has been inserted in the bore of the line to isolate the main part of the line from the pipe end having the weld. An expandable and contractable insulating ring is inserted into the pipe bore.  The ring is associated with a closure member which blanks and seals the open end of the pipe.  The isolating plug is removed and the ring is positioned beneath the weld and expanded to abut the pipe wall.  A final circumferential weld or bead is then applied to the existing weld, which causes heating of the martensitic zone. The insulating ring is maintained in place against the pipe wall to ensure that the heated zone cools only slowly. This results in reduction of the hardness of the heat-affected zone.   The isolating plug is then re-inserted and the insulating ring and closure member are removed.

Abstract: ABSTRACT OF THE INVENTION         A method and apparatus for producing turbine blade roots (23) utilize an electro-discharge machining apparatus (10) to machine critical portions of the blade root (23) and a peening apparatus (25) for peening of the machined portions.  The electro-discharge machining of the blade root leaves recast layers (22) on the surface of the blade root (23), and high residual tensile stresses are found in the surface of the blade root (23), which could lead to crack propagation.  Peening of the machined surfaces leaves compressive residual stresses near the surface and reduces the recast layers (22).  The  resulting blade root (23) meets the same specifications for durability and tolerances at a blade root machined using the conventional transfer line type cutting process, but at a fraction of the cost.
