Title: Reactor coolant pump auxiliary flexible vacuum seal for reactor coolant system vacuum degasification
Inventor: BICE CHARLES D
IPC: F04D29/10
Filed: 1990-01-05
Abstract: ABSTRACT OF THE DISCLOSURE     An auxiliary flexible vacuum seal for preparing a reactor coolant pump for vacuum degasification of the reactor coolant system employs a flexible boot member having a pair of longitudinally-displaced opposite open end portions and a pair of side-by-side longitudinally-extending side portions in the form of flanges defining a split in the boot member along a side thereof and extending  between the open end portions for allowing flexing of the boot member between open and closed side configurations to permit its installation and removal on and from the pump. The  seal  also employs clamping brackets  and  fasteners for releasably and sealably clamping together the flanges of the boot member at the split  to  retain  the  boot  member  in  its  closed configuration.   The  seal  further  includes  a pair  of circumferentially-extending  sealing portions formed integrally on the interior of the boot member at opposite open end portions thereof for sealably engaging the pump when  the boot  member  is  flexed  to  its  closed configuration to thereby permit generation of a  vacuum seal condition between the boot member and the pump. Preferably, a boot support member is disposed within the boot member between the boot member and the  pump for supporting  the boot  member  when  in  its  closed configuration.

Title: Incremental compiler for source-code development system
Inventor: MCKEEMAN WILLIAM M
IPC: G06F9/44
Filed: 1990-06-22
Abstract: INCREMENTAL COMPILER FOR SOURCE-CODE DEVELOPMENT SYSTEM     ABSTRACT:      A computer-aided software development system includes programs to implement edit, compile, link and run sequences, all from memory, at very high speed. The compiler and linker operate on an incremental basis, line-by-line or increment-by-increment, so if only one line is changed in an edit session, then only that line and lines related to it need be recompiled if no other code is affected; linking is also done in a manner to save and re-use parts of link tables and link lists which are not changed from one edit session to another. Dependency analysis may be performed incrementally, without requiring the user to enter dependencies. Scanning is also done incrementally, and the resulting token lists and token tables, and lexical increment tables, are saved in memory to be used again where no changes are made. All of the linking tables are saved in memory so there is no need to generate link tables for increments of code where no changes in links are needed. The parser is able to skip lines or blocks of lines of source code whichhaven't been changed; for this purpose, each line of source text in the editor has a change-tag to indicate whether this line has been changed, and from this change-tag information a clean-lines table is built having a clean-lines indication for each line of source code, indicating how many clean lines follow the present line. All of the source code text modules, the token lists, symbol tables, code tables andrelated data saved from one compile to another are maintained in virtual memory rather than in files so that speed of operation is enhanced. Also, the object code created is maintained in memory rather than in a file, and executed from this memory image, to reduce delays. A virtual memory management arrangement for the system assures that all of the needed data modules and code is present in real memory in the phase being implemented, with a minimum of page faults and page swapping during the phase, again to enhance operating speed.

Title: Coincinerator apparatus and method for processing waste gases
Inventor: VICKERY EARL
IPC: F23M5/08
Filed: 1990-07-25
Abstract: Abstract of the Disclosure A  method  and  apparatus  for  the  more complete incineration  of  dangerous  waste  gases  to  produce by-products which are safer for eventual release into the  atmosphere.   The  invention  involves  mixing  the waste gases with a flammable co-incineration fuel at an upstream    location    which    is    devoid    of    a combustion-supporting  atmosphere,  moving the mixture downstream to an ignitor fuel flame, and introducing a source of oxygen immediately downstream of the flame to support the combustion of the flame.  The flame ignites the  co-incineration  fuel  which,  together  with  the flame,  co-incinerates  the  waste  gases  in  an  area between the upstream area at which the waste and fuel gases are mixed and the downstream area at which the source  of  oxygen  is  admitted.   The  invention  also preferably  includes  centering  the  co-incineration reaction  for  "cold  wall"  operation,   mixing  the by-products with air for cooling purposes.
