Title: Heavy oil emulsified fuel combustion apparatus
Inventor: UEDA KATSUYUKI
IPC: C10L1/32
Filed: 1998-03-10
Granted: 2002-05-28
Abstract: A heavy oil emulsified fuel combustion apparatus is provided in which steam bubbles generated in the pressure reduction operation for dewatering a heavy oil emulsified fuel before combustion are prevented from mixing into a dewatered heavy oil side resulting in lowering of a dewatering efficiency.        In a heavy oil emulsified fuel combustion boiler, a heavy oil emulsified fuel 101 is heated by a heater 110 and dewatered by a flusher 120 and then introduced into a boiler for combustion, and water 152 obtained by the dewatering is sent to a water utilizing system of the boiler. The heavy oil emulsified fuel 102 is heated in a high pressure and then introduced into a pressure reducing device 200 to be applied by a pressure reduction by multi-stage orifices 201 for dewatering. The pressure reduction is done with a pressure reduction per stage of 1 to 3 ata.

Abstract: An articulating connector for a mandibular repositioning appliance comprises upper and lower housings each pivotally mounted on a pin and rotatable about the axis of the pin, to selectively permit movement of the mandible in the lateral direction. The pins are hingedly connected respectively to threaded adjusting screws to selectively permit movement of the mandible in the vertical direction.  The adjusting screws have opposite thread directions and are engaged within a collar, rotation of which sets a desired spacing between the adjusting screws to fix the position of the mandible in the anterior/posterior directions. Optionally the lateral and/or vertical hinges can be locked to restrain lateral and/or vertical movement of the mandible. An appliance embodying the invention can be used to alleviate snoring and sleep apnea, and certain types of temporal mandibular dysfunction, to reposition the mandible in functional appliance therapy such as far CI II patients, for orthodontic treatment of retronagthic mandible, in TMJ  pain treatment, and to retain the mandible in a forward opening position wherever limited movement is desired, for example for therapeutic purposes or in post pharyngeal operations and examinations.

Abstract: A method and apparatus for compression molding plastic articles such as closures include a plurality of tools mounted in opposed pairs with the tools of each pair including opposed male and female mold sections. The tool pairs are mounted for motion in an endless path. The tool pairs and associated mold sections are closed during motion in the path for compression a molding charge in the mold cavity formed between the mold sections of each pair and opened to release an article formed between the mold sections. A latch mechanism is associated with each pair of tools for holding the tools and mold sections in the closed position during motion in the path independent of the mechanism for closing the tools and mold halves. In this way, forces imparted to the mold halves and tools to hold the mold closed are isolated from the machine frame. The latch mechanism is selectively unlatched to permit opening of the mold halves and release of the article compression-molded between the mold halves.

Abstract: Methods and systems for measuring signal strength of supervisory audio tones (SATs) in radiocommunication systems are disclosed. Exemplary embodiments describe how such measurements may be performed using digital signal processing techniques, while reducing the amount of computing power, e.g., MIPs, used to accomplish this task. During each measurement interval a large number of SAT signal samples are received. Rather than process a complete measurement interval of received SAT samples, exemplary embodiments rely on a sliding average of samples which include both current and previous blocks of samples. In this way, the SAT signal strength can be reported relatively frequently to the system but without the number of computations that would be required to process all of the SAT signal samples received during a measurement interval.

Abstract: The method is based on consensus analyses of classifications at the object level carried out by learning systems. To determine persons or groups of persons ability to analyse details, e.g. in visual objects, digitised images of the objects are feed into a computer, where each image is assigned a number of characteristics,N out of Q possible. Some of the characteristics in the images are being selected, after which a person is set to identify the images by determination of the characteristics. The same image in a series of images is presented for the person several times, and if the person is capable to distinguish the images from each other, and furthermore reach the same results with the same images, then the person possess good abilities for type determination of reference signals, e.g. in form of images. The invention is suitable to identify persons, who are gifted for analysis of e.g. biological samples, such as images samples of semen samples, cancer cells, etc.

Title: Gas burner
Inventor: SZUCS FRANK T JR
IPC: F23D14/10
Filed: 1998-03-05
Granted: 2009-05-26
Abstract: A gas burner that produces a yellow flame for use in a fireplace assembly, including front and rear non-combustible logs and a cross-over log supported atop the front and rear logs. The burner includes an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element and to define at least one primary air opening arranged to admit combustion air into the tubular burner segment. A bluff body is located downstream from the gas orifice element and is positioned such that gas emitted by the orifice impinges on the bluff body. Rows of slot-like flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern and include tabs which determine the effective size of the ports. In regions of the burner located below the crossover log, flame ports are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting. In alternate embodiments, the bluff body is formed by a pair of confronting depressions that define a pair of venturi channels which define the mixing chamber. In another embodiment, the confronting depressions are spaced apart and mount a cylindrical bluff element therebetween. The use of venturi channels eliminates or substantially reduces the incidence of light back.

Abstract: A new oral polymeric controlled release formulation suitable for the once-a- day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior art. This formulation minimizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.
