Title: Apparatus for separating solid material in a circulating fluidized bed reactor
Inventor: ENGSTROM FOLKE
IPC: F27B15/12
Filed: 1985-11-01
Granted: 1990-01-23
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for use in a circulating fluidized bed reactor for separating solid material from the flue gases and for recirculating the solid material to the reactor. The apparatus comprises a duct for directing the flue gases from the reactor slantingly downwards to a return duct adapted to return a part of the flues laden with solid particles back to the reactor. At a point of entry of particle laden gases into the return duct, a deflecting wall diverts a major portion of the gases to the inlet of a vortex separator. The separator chamber has a discharge opening concentrical with its generally horizontal axis, for discharge of flues from which solid particles have been removed.

Title: Stimulation of biooxidation processes in subterranean formations
Inventor: RAYMOND RICHARD L
IPC: C09K17/00
Filed: 1985-11-04
Granted: 1990-05-15
Abstract: ABSTRACT: STIMULATION OF BIOOXIDATION PROCESS IN SUBTERRANEAN FORMATIONS The present invention is a process to stimulate the biooxidation of a contaminant in a subterranean formation by introducing an aqueous solution into the formation. The concentration of the hydrogen per-oxide is increased thereby acclimating the biota to higher concentrations of hydrogen peroxide. Peri-odically the concentration of the hydrogen peroxide is increased for a short time sufficiently to be toxic to the biota at or relatively adjacent to the site of introduction, thereby increasing the perme-ability of the formation at or adjacent to the site of introduction.

Abstract: ABSTRACT     IMPROVEMENTS IN OR RELATED TO GAS TURBINE ENGINES            A variable cycle gas turbine bypass engine includes a first fan 1 located at an inlet to the engine so as to provide air to a compressor 2 driven by a turbine 11 and to a bypass duct 13 surrounding the compressor housing. A second fan 5 located in the bypass duct 13 is driven by a free turbine 12.  A controllable area auxiliary air intake 4 and bypass duct blocker doors 3 are located between the first and second fans 1, 5. Control means are effective for selectably operating the bypass duct blocker doors 3 and the auxiliary air intake 4 to vary in operation the bypass ratio of the engine. Thus in conventional wing-borne flight, the intake 4 is closed and the bypass duct 13 is unobstructed, and the combined exhausts from the bypass duct 13 and the turbines 10, 11 and 12 pass to a tailpipe 14, which has a vectorable nozzle 8, to produce forward thrust. In jet-borne flight, however, the doors 3 block the bypass duct 13, the auxiliary air intake 4 is opened to admit air to the second fan 5, and a vectorable nozzle 9 with associated blocker doors 3a and the nozzle 8 are  operated by the control means respectively to receive air from the first fan 1 and the exhausts from the second fan 5 and the turbines 10, 11  and 12.

Abstract: DEVICES AND DEVICE FABRICATION    WITH BOROSILICATE GLASS            Abstract Semiconductor devices are described which are made by a process involving the use of certain types of glass layers. These glass layers have highsilica content, small amounts of boron oxide and optionally small amounts of aluminum oxide. The glass layers are put down by e-beam deposition procedure using a glass target made from restructured glass. Commercial availability of such glass makes the procedure very convenient. Such glass layers are advantageously used as barrier layers in annealing procedures used when semiconductors are doped (e.g., ion implantation in semiconductors) and as encapsulating layers in finished devices.

Filed: 1987-12-07
Granted: 1992-01-28
Abstract: ABSTRACT           A process for preparing a dense, consolidated body from a preform.  The process requires compressing the preform in a forging press in an isostatic die assembly.  The assembly includes an open top, ceramic-containing shell and a pressure-transmitting medium wherein the preform is placed in the shell and surrounded by the medium.  The assembly and, hence, the preform are compressed under such conditions of temperature, time and pressure that a dense, consolidated body of desired shape is formed.  The process then requires recovering the body by separating the body from the fluid pressure-transmitting medium.     35,124-F

Abstract: A B S T R A C T         "Data Compression Apparatus and Method for Data Recorder with Waveform Envelope Display"            A data compression method and apparatus particularly suitable for use in electrical power line fault data recorders. The system performs both gain compression and frequency compression. For gain compression, a predetermined number of samples are analyzed to determine a gain setting common to each sample in the set of samples. A reduced data string consisting of a gain code and data words having fewer bits than the input words are transmitted as a compressed data string. For frequency compression, a sample set representing the input signal is decimated until there remain only a sufficient number of data samples to satisfy the Nyquist criterion for the highest frequency component of interest. Also included is a circuit for reproducing the waveform envelope. Positive and negative peak detectors provide signals representative of the peaks of the waveforms. These positive and negative peak signals are then compressed with the gain compression circuit, decompressed after transmission or recall, and then displayed as an envelope waveform for allowing trend analysis.

Abstract: DAMPING ASSEMBLY FOR A TORQUE CONVERTER CLUTCH            Abstract of the Disclosure A torque converter turbine, clutch and output shaft are interconnected by a planetary gear arrangement.  The gear arrangement combines the output of the turbine and clutch, when engaged, at the torque converter output shaft.  The turbine provides a reaction for the gear set so that transient torque spikes, or torsional vibrations, are effectively dampened by permitting the turbine to decrease in speed, and thereby absorb the torque spike energy.  A one-way clutch, between the turbine and output shaft, prevents the turbine from overrunning the output shaft. The one-way clutch transmits torque from the turbine to the output shaft when the torque converter clutch is disengaged.
