Title: Cyclic demand steam supply system.
Inventor: WILLIAMS EDDY A
IPC: F01K1/06
Filed: 1991-11-25
Abstract: A steam system is disclosed having a steam boiler (14) designed to produce an adjustable supply of boiler steam and a steam accumulator (12) designed to supply all of the steam to steam load (66) as opposed to functioning as an auxiliary source to boiler (14). Steam accumulator (12) is a pressure vessel designed to function as a wet steam accumulator and sized to provide large quantities of steam in short bursts for a predetermined period of time to a sustained cyclic steam load (66) for a period of time sufficient to compensate for the time delays necessary to adjust the boiler steam produciton rate to equal changes in the average of the cyclic demand load. Accumulator (12) is formed of a pressurized vessel having a plurality of tubes (54) therein which are designed to have a sufficient heat transfer surface to transfer the majority of energy from boiler steam to the heated accumulator water (67) through conduction of heat through the tube heat transfer surfaces so that the majority of the boiler steam is actually condensed prior to being discharged into the heated accumulator water (67).

Title: Osteoinductive protein mixtures and purification processes.
Inventor: POSER JAMES WILLIAM
IPC: A61F2/28
Filed: 1992-04-21
Abstract: A method for purifying bone-derived osteoinductive factors including an ultrafiltration process, an anion exchange process, a cation exchange process, and a reverse phase HPLC process. The ultrafiltration process preferably includes a first ultrafiltration step using a membrane having a nominal molecular weight cutoff of approximately 100 kilodaltons (kD) and a second ultrafiltration step employing a membrane having a nominal molecular weight cutoff of approximately 10 kD. For the anion exchange process, a strongly cationic resin is used, preferably having quaternary amine functional groups. Typically, the eluant for the anion exchange process has a conductivity from about 10,260 micromhos ( mu mhos) (1.026x10-2 siemens (S)) to about 11,200  mu mhos (1.120x1031 2 S). For the cation exchange process, a strongly anionic resin is used, preferably having sulfonic acid functional groups. The eluant for the cation exchange process typically has a conductivity from about 39,100  mu mhos (3.91x10-2 S) to about 82,700  mu mhos (8.27x10-2 S) or more. The HPLC process typically utilizes a column containing hydrocarbon-modified silica packing material. The osteoinductive proteins can be eluted from the HPLC column with an acetonitrile solution in combination with aqueous trifluoracetic acid. The purification processes yield osteoinductively active protein mixtures.

Abstract: Une cellule d'analyse de gaz (110), placée dans la cavité optique résonnante d'un dispositif d'analyse de gaz, permet un flux de gaz tampon qui vient former ''barrage'' et ainsi protéger les éléments optiques (120, 122) dudit système d'analyse. La cellule d'analyse (110) comporte une entrée (134) autorisant l'arrivée d'un échantillon de gaz dans sa chambre d'analyse (126). On a ménagé deux lumières d'entrée (140, 142), une à chaque extrémité de la cellule, pour faire passer un flux de gaz tampon jusqu'au-delà des éléments optiques (120-122) du dispositif placés près des extrémités de la cellule. Deux lumières de sortie (144, 146) sont placées aux extrémités de la chambre d'analyse (126) pour qu'on puisse extraire le mélange du gaz tampon et de l'échantillon. Le flux de gaz tampon confine l'échantillon de gaz dans la chambre d'analyse (126) et limite les inconvénients survenant lorsque l'échantillon de gaz entre en contact avec les éléments optiques (120-122) du dispositif. Grâce à un flux régulier non turbulent de gaz passant contre l'optique du dispositif, on évite des changements néfastes de l'indice de réfraction, ce qui limite la déviation du faisceau et les effets strioscopiques pouvant survenir quand on utilise des fenêtres de Brewster ou d'autres optiques pour confiner l'échantillon de gaz cans la cellule d'analyse. Le flux de gaz tampon présent dans la cellule d'analyse (100) de cette invention évite de devoir y monter des fenêtres qui entraînent des pertes intrinsèques, lesquelles affaiblissent à leur tour la puissance de circulation dans la cavité et la force du signal.

Patent EP-0912810-A4 (EP)
Title: Lock system with key trapping
Inventor: EDEN CHARLES W JR
IPC: E05B11/06
Filed: 1997-07-18
Abstract: A novel lock system utilizes a cylinder lock and a companion key with a projection extending from one side thereof to improve security. The cylinder lock comprises a shell, a core which is rotatably mounted within the shell and a plurality of pin tumbler stacks normally prevent movement between the shell member and the core. Shear lines are defined between the shell and the core, and also within each tumbler stack. The core also includes an outer surface, a longitudinal keyway and a cut-out which is normally offset from, but alignable with, at least one of the tumbler stacks. A plate member is disposed within the cut-out for movement between a first position, wherein the plate member acts as an extension of the core surface to prevent a tumbler stack from entering the cut-out and a second position, wherein the plate member does not prevent a tumbler stack from entering the cut-out. Upon insertion of an authorized key, the key bitting will appropriately align the tumbler shear lines with the shell/core shear line, and the key projection will urge the plate from the second position to the first position and thereby permit the core to rotate to an unlocked position. Upon insertion of a properly bitted key which does not possess an appropriate key projection, however, only partial core rotation is permitted whereupon a tumbler stack enters the cut-out to thereby render the lock inoperable and trap the unauthorized key within the keyway.

Title: Method and apparatus for total energy fuel conversion systems
Inventor: ENNIS BERNARD P
IPC: C06D5/00
Filed: 1997-12-23
Abstract: An independent and conserved source of fuel and/or power comprises a top stage rocket engine firing up to 5000 F at very high pressures, delivering jet flows up to transonic velocities into a near adiabatic tunnel for mixing in general and/or for transforming reactants introduced to suit specific objectives. The related compression is supplied by an independent prime mover which compresses its exhaust and other recoverable fluids. Low grade flows, thereby upgraded in temperature and pressure, are adiabatically contained, are further upgraded in the tunnel to become part of the prescribed fuel for export at the tunnel ends; or fuel to be fired in a prime mover for electric or other power, or hydrogen for chemical use. Expansion turbines for this purpose are relieved of the load used to compress the excess air in standard gas turbines thus increasing export power. A portion of the expansion turbine's exhaust becomes part of recoverable fluids. When oxygen is used instead of air, the gases through turbines are nitrogen-free with more heat capacity reducing turbine inlet temperatures for the same power. When reactant transfonnation is specified, the larger water vapor content in the cycle enhances the water gas/shift autothermally for ammonia and/or power and alternatively for pyrolysis cracking for olefins and diolefins. Further, staging rocket engine reactors increases efficiency in boilers and steam turbines; and staging can produce sponge iron and/or iron carbide as well as expansion turbine power and fuel cells for peak and off-peak loads,
