Title: Methods of preparing substituted tetracyclines with transition metal-based chemistries
Inventor: KOZA DARRELL J
IPC: C07C237/26
Filed: 2000-09-13
Abstract: The present invention relates to novel chemistries which allow for heretofore unobtainable substituted tetracycline compounds which exhibit significant antibacterial activity. The methods disclosed herein utilize reactive tetracycline-based precursor compounds, reactive organic substituent precursors and transition metal catalysts under conditions such that a tetracycline compound substituted with the desired organic substituent is formed. In one embodiment of the invention, a substituted tetracycline compound may be prepared by combining a reactive tetracycline-based precursor compound such as an arene tetracycline diazonium salt, and a reactive organic substituent precursor, e.g., alkenes, substituted alkenes, vinyl monomers, aromatics and heteroaromatics, in the presence of a transition metal catalyst, such as palladium chloride, under conditions such that a tetracycline compound substituted with the organic substituent is formed. Such compounds may optionally act as intermediates for making other compounds, e.g., hydrogenation of unsaturated groups on the substituent.

Abstract: A fluid flow regulator (10) of a type having a variable outlet defined by a spacing between an outlet aperture (24) and a flexible diaphragm (14), and i n which the position of the flexible diaphragm (14) varies as a function of a pressure differential between a sensing chamber (16) on a first side of the diaphragm and an outlet chamber (18) on a second side of the diaphragm. The regulator (10) includes an adjustable flow impedance configuration (22) in t he flow path from the sensing chamber (16) to the outlet chamber (18), the flow  impedance configuration (22) defined by two cylindrical elements (12, 20) having opposing cylindrical surfaces (26, 28) which are in sliding contact. One of the cylindrical surfaces (26, 28) has a groove (30) configured to define a flow-attenuating passageway having a net flow vector substantially parallel to the axis of the cylindrical surfaces (26, 28). Axial relative movement between the elements (12, 20) causes a variation in an extent of overlap between the cylindrical surfaces (26, 28), thereby varying an operative length of the flow-attenuating passageway.

Title: Cfb with controllable in-bed heat exchanger
Inventor: WALKER DAVID J
IPC: F22B31/00
Filed: 2002-07-15
Abstract: A circulating fluidized bed (CFB) boiler has one or more bubbling fluidized bed enclosures containing heating surfaces and located within a lower portion of the CFB boiler to provide a compact, efficient design with a reduced footprint area. The heating surfaces are provided within the bubbling fluidized bed located above a CFB grid and/or in a moving packed bed below the CFB grid inside the lower portion of the CFB boiler. Solids in the bubbling fluidized bed are maintained in a slow bubbling fluidized bed state by separately controlled fluidization gas supplies. Separately controlled fluidization gas is used to control bed level in the bubbling fluidized beds or to control the throughput of solids through the bubbling fluidized beds. Solids ejected from the bubbling fluidized beds can be returned directly into the surrounding CFB environment of the CFB boiler, or purged from the system for disposal or recycle back into the CFB. Solids which are recycled back to the CFB have less heat and can be used to control the temperature of the fast moving bed in the CFB.

Abstract: A single, common correlation filter (CF) core is provided in a wireless syst em using CDMA (code division multiple access). A plurality of channels with different data rates are provided in the wireless system. The channels provided in the wireless system include the access channel, the maintenance channel, and the traffic channel in which information (e.g., pilot or data symbols or both) is transmitted at the tier 1 (which is the basic despreadin g rate), tier 2 and tier 3 rates. The data rate for transmitting the informati on is programmable by an external programmable processor, e.g., a digital signa l processor (DSP). A user-unique code, such as a PN (pseudo-random noise) code , is applied to the information being transmitted in the channels of the wireless system. Theinformation is modulated and transmitted in any one of t he channels at any data rate. The transmitted information is correlated at the basic despreading rate (i.e., the tier 1 rate) in the correlation filter (CF ) of the wireless system by time multiplexing delayed versions of the PN code (or orthogonal code, Walsh code) to the correlation filter core. The correlated information is then demultiplexed and demodulated. The demodulate d information is summed at the proper integer multiple of the tier 1 rate to achieve the tier 2 and tier 3 rates. One or more signal components are selected (in terms of the received power, signal-to-noise ratio or multipath  width) in a window or time period for optimal information recovery. The selecting step can also be implemented according to a preprogrammed time alignment. Furthermore, outputs from the demodulated information can be provided and combined for temporal diversity. Spatial diversity is achieved by providing a plurality of antennas, and a plurality of receivers at a locatio n and providing a single, common correlation filter at each of the plurality o f antennas of the receivers in the wireless system.
