Inventor: REISS FRANK
IPC: F23R3/42
Filed: 2010-09-02
Abstract: Combustor for a turbine, and gas turbine outfitted with a combustor of this kind, wherein the combustor has a housing in which an air collecting chamber, a combustion antechamber, and a combustion chamber are formed, a combustor head plate which is arranged in the housing so that the combustor head plate separates the combustion antechamber from the combustion chamber, a baffle plate which is arranged in the combustion antechamber so that the baffle plate divides the combustion antechamber into a first sub-chamber adjoining an air supply which is fluidically connected with the air collecting chamber and a second sub-chamber adjoining the combustor head plate, wherein the baffle plate has a plurality of through-passages which fluidically connect the first sub-chamber with the second sub--chamber so that air which has flowed into the first sub-chamber from the air collecting chamber via the air supply can flow into the second sub-chamber via the through-passages and can flow to a back surface of the combustor head plate facing the second sub-chamber.

Title: Device for improved delivery of gas to fluid
Inventor: BURNS DAVID
IPC: C02F1/78
Filed: 2009-02-23
Abstract: The device is of the frustum dispersion type having a housing forming a conical cavity, sealed at its large end, ta-pering to a discharge orifice at the other end. There is a fluid inlet, which tangential to the cavity near the sealed end. There is a hollow, tapered helix cut cone shape in the center of the cavity, affixed to the sealed end, with the point thereof axially aligned with the discharge orifice to help enable the continuous swirling motion of the contained fluid and to act as a gas inlet port to start the formation of a gas vortex. As fluid in the cavity approaches the discharge orifice, it is accelerated because of the reduction of area inside the cavity as it tapers. The change in specific gravities between the fluid and the gas causes a swirling centrifugal force on the liquid and a centripetal inner swirling of the gas. The result is at the point of discharge, the fluid is heavily loaded with small bubbles of gas.

Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power "steps" that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges.    Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

Abstract: A method involves generating a partially completed tax return based on basic user information without needing to obtain other user inputs through an extensive user interview. A list of simple and concise interview questions are generated or selected from an interview question collection based on the partially completed tax return to finalize the tax return. The method further involves using an inference engine to allow data collection at any time and in any order via specific, personalized questions geared toward completion of the tax return. Therefore the taxpayer spends time reviewing rather than preparing his or her tax documents.

Abstract: The invention provides an improved use of using screws, spikes and nails in joining pieces of wood.   The intent of making use of the above named devices is to use a simple procedure to join separate pieces of wood using the Nail Screw or Twin Spike or Twin Nail.  This is easily accomplished by using a Drill and Bit as the primary method by drilling the Nail Screw end into the wood. The secondary method would be to hammer the Twin Spike or Twin Nail into the first wood piece using a very simple application tool that is applied over the shank of the nail or spike connecting with one side of the nail or spike head.   For either method, in most cases, pre drilling and countersinking would be appropriate. This would apply by using the Twin Spike, Twin Nail or the Nail Screw, where a head is in the middle of the device. When using the Nail Screw without a head in the middle, counter-sinking would not be required but pre drilling may still be appropriate.   The end result would be that no metal part is visible after completion of the job.

Abstract: An apparatus for controlling a flow of fluid and/or other bodily matter in a lumen formed by a tissue wall of a patient's organ comprises an implantable constriction device for gently constricting (i.e. without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow in the lumen, and a stimulation device for stimulating the wall portion of the tissue wall. A control device controls the stimulation device to stimulate the wall portion, as the constriction device constricts the wall portion, to cause contraction of the wall portion constricted by the constriction device to further influence the flow in the lumen. The apparatus can be used for restricting or stopping the flow in the lumen, or for actively moving the fluid in the lumen, with a low risk of injuring the organ.

Title: Endoscopic led light source having a feedback control system
Inventor: FEINGOLD BENJAMIN HYMAN
IPC: A61B1/05
Filed: 2009-11-17
Abstract: An external endoscope light source system includes light emitting diodes for providing a light output to an endoscope.  The light is provided to a fiber optic cable for transmission to the endoscope. A fiber optic receives a portion of the light output and provides the output to a color sensor for sensing color values. The color values are provided to a controller that adjusts power to the various LEDs to provide a white light output. Instead of a color sensor in the light source, the light source can receive a white balance signal from a video camera provided for an endoscope.  The white balance signal varies intensity of light output from each of the LEDs to obtain a white light output. The camera also provides shutter speed of a camera image sensor to the light source. The shutter speed is used to pulse or modulate the light output only when the shutter of the camera is open. By modulating the light output by the light source, the amount of heat generated by the light source is minimized.
