  • Patent number: 11507247
    Abstract: A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

  • Patent number: 7610850
    Abstract: An apparatus for slicing apples is provided. The slicer utilizes thinner blades than known in the art, with a thickness less than 300 microns, and preferably between 180 and 220 microns. Each of the thinner blades is supported against bending, warping or twisting by a novel clinch buckle which rigidly supports the outer end or ends of each blades. The clinch buckle is rigidly connected to bent tabs formed at the outer end or ends of each blade and supports the outer ends across the full width of the blades. The clinch buckle is supported by an outer blade support ring and is captured by the outer support ring to prevent rotation of the clinch buckle. The thinner blade reduces cell damage, reduces the amount of sealant or neutralizer needed to slow or prevent oxidation of enzymes released from cells ruptured by slicing, and delays the onset of browning. A serrated blade is used to further reduce the extent of cell damage.

  • Patent number: 6086828
    Abstract: A regenerative thermal oxidizer (H-101) includes a number of heat exchange columns (A, B) topped by a combustion chamber (C-101). Contaminated air is directed into one of the columns and oxidation is completed as the flow passes through the combustion chamber (C-101). From the combustion chamber (C-101), the now clean air flows vertically downward through another column and then is directed via an outlet through an outlet manifold and released to atmosphere or recirculated back to the oxidizer (H-101). A combustible fuel is added to the contaminated air prior to its entry into one of the columns. The addition of the combustible fuel is regulated by continuously monitoring the inlet and outlet temperatures (TE-101A, TE-108A), and comparing a difference between these temperatures to a predetermined value. Further control can be achieved by measuring the flow of contaminated air to the oxidizer (H-101) via pressure differential and coordinating that measurement with the temperature differential measurement.

  • Patent number: 5074987
    Abstract: A method and device for measuring energy in fuel gas comprises a solid electrolyte oxygen pump for generating an amount of oxygen in response to current being supplied to the pump. A sample of the gas is mixed with the oxygen from the pump to produce a mixture which is subjected to complete combustion in a catalytic combustor. An oxygen sensor is connected to the catalytic combustor for measuring excess oxygen in the exhaust gas from the combustor. A signal from the oxygen signal is compared to a known and desired amount of excess oxygen in the exhaust gas. If there is too much or too little oxygen inthe exhaust gas, a feedback signal is used to adjust the amount of current being supplied to the oxygen pump until the actual amount of excess oxygen is equal to the selected amount of excess oxygen. The selected amount of excess oxygen is indicative of complete combustion of the sample mixture.

  • Patent number: 5072504
    Abstract: The invention is directed to a method for axially and externally mounting an expandable sleeve onto, and dismounting the sleeve from, a cylinder. The subject method utilizes an external fluid-transmission means for expanding the diameter of the expandable sleeve by introducing a fluid capable of expanding the sleeve between the inner surface of the sleeve and the outer surface of the cylinder. The requisite sleeve expansion is accomplished without transmitting fluid from within the cylinder during the mounting and dismounting operations. The sleeve is contractable by the removal of the fluid.

  • Patent number: 5062193
    Abstract: The invention relates to a device for axially, externally mounting a expandable sleeve onto, and dismounting a expandable sleeve from, a cylinder, comprises an external fluid-transmission means which comprises a plurality of sections. These sections are attachable and detachable from each other for facilitating engagement and disengagement of the external fluid-transmission means with respect to the sleeve. In one form of this invention, the external fluid-transmission means sections are connected to each other at one of its respective ends, typically pivotally connected to each other. The other end of each the fluid-transmission means sections are then movable in an arcuate path between a closed position in which the fluid-transmission means section ends are in engagement with each other, and an open position in which the fluid-transmission means section ends are in disengagement with each other.

  • Patent number: 5025665
    Abstract: An on-line system that measures the strength of material within a web without contacting same is disclosed. Two laser sources having beams which impinge upon the web of material are positioned so that their respective beams are spaced a predetermined distance apart. The first laser source induces a radially propagating ultrasonic wave within the material. The ultrasonic wave causes the beam from the second laser source to be reflected and intercepted by a light sensor permitting the velocity of the wave and the strength of the material to be determined.

  • Patent number: 4816703
    Abstract: An on-line serial communication interface is established from the transmitter of a two line current loop transmitter to a digital circuit such as a computer or hand-held terminal which receives and processes digital voltage pulses. The interface includes a comparator having a positive terminal connected by a capacitor to one of the current lines, and a negative terminal connected to a source of small positive voltage. The output of the comparator is connected to an input port of the digital device. The transmitter modulates the current on the current loop by a small amount with respect to the analog current communicated by the transmitter. This generates voltage pulses in the capacitor which are compared to the selected voltage and are amplified to form large pulses used for communication with the computer or hand-held terminal.

  • Patent number: 4729125
    Abstract: A serial communication interface establishes communication to the microprocessor of a transmitter, from a current loop which is powered by a power supply. The microprocessor outputs an analog signal corresponding to a process variable and also can receive a serial communication voltage pulse signal. The analog signal is applied to a current regulating circuit which draws current from the power supply onto the current loop in an amount which is proportional to the process variable. A comparator in the form of an operational amplifier has an output connected to the microprocessor for applying the serial communication voltage pulse signal to the microprocessor. The comparator has one input which is held at a slight negative voltage and another input which is connected to a line of the current loop connected to the negative terminal of the power supply.

  • Patent number: 4691328
    Abstract: An on-line serial communication interface is established from a digital circuit such as a computer or hand held terminal, to a current loop which has lines for connecting a transmitter to a power supply. The interface includes a diode which is connected in series with one of the lines of the current loop. The diode is connected in parallel to the source and drain of a FET. The control gate of the FET is connected to the output of a differential amplifier who receives as one of its inputs, a digital voltage pulse signal from the digital circuit. The other input of the amplifier is held at a selected voltage so that voltage pulses are output from the amplifier when the digital circuit generates its voltage pulses. This turns the FET on and off in synchronism with the voltage pulses, thus cutting the diode in and out of series with the line of the current loop. With the FET in its non-conducting off condition, the diode has a small voltage drop thereacross. This does not effect the current on the current loop.
