Granted: 1997-05-20
Abstract: A high frequency, high voltage starting circuit (10) for a plasma arc cutting torch (16) is operated in pulses to restart the torch if an initial arc extinguishes before the arc transfers to the workpiece (24). The starting circuit (1) includes a D.C. power supply (28) with its negative output (28A) connected to an electrode (18) of the torch (16). A positive output (29b) is connected to a nozzle (22), and at a higher positive voltage, to a workpiece (24). A surge injector circuit (38) of a resistor (R2) and surge capaci-tor (C4) is connected in parallel with the power supply to supply current to the arc as soon as breakdown occurs. The duration of the interval between restart pulses is sufficient to allow the surge injector circuit (38) to recharge to a value that will reliably restart the arc as the power supply ramps up to a steady state pilot arc current.

Title: A method and system for audio information dissemination using various transmission modes
Inventor: RYAN JOHN O
IPC: G10L19/00
Filed: 1995-01-12
Granted: 2008-04-01
Abstract: A system and method of information dissemination that permits the user to listen to the specific content of information when and where he or she wants to. A radio or television receiver system receives information from an FM  subcarrier, a television vertical blanking interval transmission, a television separate audio program transmission or a dedicated channel and stores the transmitted information in a memory. A user interface allows selection from the memory of the stored information via a set of menus controlling a hierarchical database, so as to access particular items of information.  Typically, the system includes RAM and/or a storage medium such as a digital audio tape, a magneto-optical mini-disk, a magnetic disk or optical disk, sufficient to store information for 10 hours of audio. A decompression device accepts the accessed compressed digital audio information items which may have been encrypted and transforms them into spoken speech. The user interface is either by voice or a single or multi-position switch allowing scanning through and selection from the menu items. The signal for such a device is generated by converting analog audio signals into a digital audio data stream which may be encrypted. The encrypted digital data stream is compressed and inserted on the radio or television carrier via an FM subcarrier, the television vertical interval or the separate audio program channel of a television transmitter.  The system is also capable of transmitting alphanumeric data and converting this alphanumeric data to a voice form using a speech synthesizer.

Title: System and method for noninvasive hematocrit monitoring
Inventor: STEUER ROBERT R
IPC: A61B5/1455
Filed: 1993-04-12
Granted: 2004-06-22
Abstract: A system for determining the hematocrit transcutaneously and noninvasively. Disclosed are a finger clip assembly (6) and an earlobe clip assembly (10), each including at least a pair of emitters (1, 2) and a photodiode (3) in appropriate alignment to enable operation in either a transmittion mode or a reflectance mode. At least two, and preferably three, predetermined wavelengths of light are passed onto or through body tissues such as the finger (7), earlobe (11), or scalp, etc. and the extinction of each wavelength is detected.      Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If a fourth wavelength of light is used which is extinguished substantially differently by oxyhemoglobin and reduced hemoglobin and which is not substantially extinguished by plasma, then the blood oxygen saturation value, is determinable independently of the hematocrit value. It is also within the scope of the present invention to detect and analyze multiple wavelengths using a logarithmic DC  analysis technique. In this embodiment, a pulse wave is not required. Hence, this embodiment may be utilized in states of low blood pressure or low blood flow.

Granted: 2000-08-01
Abstract: An automatic dishwashing machine includes enhanced drying and draining cycles.  Toward the end of the rinse and hold cycle when the water is draining, a second quantity of water is added to the machine resulting in a purging action which reduces the concentration of soil in the wash pump.  During the normal wash cycle, if the dishwashing machine determines that the water is sufficiently dirty, a second drain is initiated to remove any dirty water that is present in the bottom of the pump after the first drain.  During the dry cycle, the machine senses the temperature of the water and the presence of a rinse aid to select an appropriate dry cycle.  The possible dry cycles include a delayed dry cycle and a pulsed dry cycle.

Abstract: Combustion gas is fed to a furnace, preferably a recovery boiler for combusting black liquor from cellulose pulp processing, through a gas nozzle disposed in association with a wall of the furnace. The nozzle has a longitudinal axis of elongation, an exterior, and a hollow interior. Cooling gas is directed into contact with the nozzle exterior, and typically also the furnace wall where the nozzle engages the furnace wall. The cooling gas typically moves in a direction substantially perpendicular to the longitudinal axis of the nozzle, and cools the nozzle. Combustion gas passes through the nozzle hollow interior and enters the furnace facilitating combustion of black liquor within the furnace. Desirably the cooling gas is redirected and enters the nozzle interior as the combustion gas. The nozzle may be further cooled by cooling fins or studs on a portion of the nozzle exterior impacted by cooling gas. The rate of gas flow may be regulated to control the amount of gas redirected into the nozzle for use as combustion gas. The invention results in effective cooling of the nozzle to extend its life, recovery of heat from the nozzle by utilizing it to preheat the combustion air, and the prevention of clogging of the cooling air flow paths because they are maintained distinct from areas where furnace impurities exist.
