Abstract: APPARATUS AND METHOD FOR SERVICING             INTERRUPTS UTILIZING A PENDED BUS                ABSTRACT OF THE INVENTION Apparatus and method for servicing interrupt requests on a pended bus.  An interrupt servicing node provides interrupt acknowledge messages including destination data specifying a particular interrupting node at times when the interrupt servicing node is ready to service an interrupt request message. The interrupt servicing node includes storage means for speci-fying the identity of a particular interrupting node and for indicating that an interrupt request is pending from a particu-lar interrupting node.  An interrupting node provides to the pended bus an interrupt request message including ID data for identifying the interrupting node as the source of an interrupt request.  The interrupting node detects whether an interrupt acknowledge message on the bus includes destination data speci-fying that interrupting node.

Title: Method and apparatus for controlling the temperature of a liquid
Inventor: SPERLING JAC K
IPC: G05D23/12
Filed: 1988-07-12
Granted: 1992-01-28
Abstract: Abstract A liquid temperature controlling method and ap-paratus are provided in which on/off valves are util-ized.  In the case in which the liquid is water, rela-tively hot water is supplied to a first set of the on/off valves while relatively cold water is supplied to a second set of the on/off valves.  The on/off valves are housed in a compact manifold assembly having a number of channels through which water flows to and from the valves.  Each of the valves communicates with an orifice, with each orifice communicating with the hot water valves being of a different size to produce binary flow patterns of water exiting the hot water as-sociated orifices and valves.  Similarly, each of the orifices communicating with a cold water valve is of a different size so that the flow rate of water from each cold water associated orifice is related in a binary manner to the flow rates through the other cold water associated orifices and valves.  Because of the greate-viscosity of the hot water, it is preferable that the hot water associated orifices be of a smaller size than corresponding cold water orifices.  The opening/closing of the valves is controlled using information stored in memory.  The programmed information correlates valve openings with information relating to water tempera-ture.  The user selects a desired water temperature and this temperature is compared with the actual tempera-ture of the water.  When there is a difference between the actual and desired temperatures, one or more dif-ferent combinations of valves can be opened in a predetermined manner without cycling through all pos-sible valve combinations defined between the current combination of valve openings and the next combination of valve openings whereby the difference between the actual and desired temperatures is rapidly reduced.

Granted: 1991-04-30
Abstract: Abstract of the Disclosure A sensor (24) having a metal shell (30) joined to a sleeve (96) to locate a heater (92) in a thimble of an electrolyte member (72).  A sealed joint is produced between the sleeve (96) and metal shell (30) to define a sealed reference chamber (118).  A porous filter (112) in the sleeve (96) prevents water in environmental air from entering the reference chamber (118).  Leads (106') and (106") which pass through a seal (123) adjacent the porous filter (112) are connected to terminals (164 and 164').  Terminals (164 and 164') located in a terminal member (120) position a heater (92) within chamber (118) and the electrolyte member (72).  Leads (106 and 106n) which pass through the porous filter are connected to contact rings (142 and 144).  Contact rings (142 and 144) are connected to an external and internal coating (80 and 82) on the electrolyte member (72).  In response to a signal from a controller (26) electrical current is supplied to the heater (92) to maintain the temperature in chamber (118) above present limits such that changes in the ion conduction through the electrolyte member (72) is accurately measured.  The changes result from a difference in the oxygen content of air in the reference chamber (118) as compared with oxygen in an exhaust gas supplied to the external surface (80).  The seal (123) and filter (112) are free to move axially within the sleeve (96) while still maintaining radial engagement to assure that only dry environmental air is presented to the reference chamber (18).

Title: Dispositif de ramonage mecanise
Inventor: BERTRAND BERNARD
IPC: B08B9/04
Filed: 1988-11-03
Granted: 1993-03-30
Abstract: Un dispositif de ramonage automatisé pour la cheminée, grâce auquel l'on peut commander à partir du sol l'actionnement de la brosse de ramonage laquelle se déplacera verticalement dans le conduit de fumée de la cheminée en grattant ses parois intérieures afin d'en déloger la créosote. La brosse comprend deux demi-corps annulaires avec une multitude de poils semirigides sur la périphérie de leur bords arrondis, ces corps étant reliés à une longue vis sans fin installée en position verticale dans la cheminée. Les deux demi-corps peuvent coulisser l'un par rapport à l'autre dans un plan horizontal, et sont écartés par la contrainte d'un ressort. Lorsque la vis sans fin tourne, la brosse se déplace verticalement. Ainsi, la tension du ressort favorise le grattage de la paroi interne de la cheminée par les poils de la cheminée, tout en permettant de complètement dégager l'ouverture supérieure de la cheminée lorsque la brosse est en position inopérante afin de favoriser l'appel d'air ambiant et l'évacuation des fumées du feu de foyer.

Title: Screening for antibodies which bind carbohydrate epitopes of tumor-associated antigens, and uses thereof
Inventor: JETTE DIANE
IPC: G01N33/574
Filed: 1988-12-23
Granted: 1999-01-12
Abstract: Cells which produce antibodies which bind carbohydrate epitopes of glycoproteins are identified by screening with mucinous body fluids in raw, or preferably partially purified, form.  Fine differences in antibody specificity may be detected by further screening with mucinous body fluids treated to alter the carbohydrate epitope interest, e.g., removal of sialic acid from a sialosyl Lewis-a epitope.  The selected antibodies may be used in immunopurification, immunodiagnosis and immunotherapy.     By this method, antibodies have been found whose binding to carbohydrate epitopes such as sialosyl Lewis-a is relatively insensitive to pH.  Such antibodies are of particular value in immunological methods where pH is a consideration.

Abstract: THERMALLY INSULATED QUENCH RING FOR A GASIFIER                 (D#78, 760-F) ABSTRACT           Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell.  A reac-tion chamber within the shell receives a fuel mixture from an injection burner.   The products or effluent of gasification include hot produced gases which are passed through a con-stricted throat to be cooled in a liquid bath.  A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring.  The latter is supported below the reaction chamber and is provided with a thermal bar-rier along its surface that is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.
