Title: Impedance feedback electrosurgical system
Inventor: NARDELLA PAUL C
IPC: A61B18/14
Filed: 1994-04-29
Granted: 2008-01-22
Abstract: An impedance feedback electro-surgical system (100) is useful with electro-surgical tools (102) to maintain a preselected control range of tissue impedance within the tissue in contact with the tool (102). The system comprises an active electrode (108) associated with an electro-surgical tool (102), a return electrode (112), in the form of a remote ground pad which is in contact with the patient, an impedance monitoring device (116) and a power control unit (120). Energy sufficient to affect tissue is delivered through the active electrode (108) to tissue and to the return electrode. The impedance measuring device (116) determines the impedance of the tissue based on the voltage differential between the active electrode (108) and ground pad (112). A signal representative of the measured impedance is communicated to the power control unit (120) which adjusts the energy applied to the tissue to maintain a preselected impedance range.

Title: Specially shaped auger compactor housing section for effecting even distribution of material into bale-forming chamber having rectangular cross section
Inventor: DOLBERG DALE RAY
IPC: B30B9/30
Filed: 1996-05-01
Granted: 1999-06-29
Abstract: A baler for forming parallelepiped bales includes an auger compactor located within a mainly cylindrical auger housing having a rear transition section including four corner feed structures spaced equally about the auger housing longitudinal axis.  Each corner feed structure is defined by a pair of walls joined to define a corner which leads to a respective corner of a rectangular cross section bale-forming chamber at the rear end of the auger housing.  The junction of one of the walls of each corner structure with the cylindrical auger housing is generally oriented so as to be crosswise to the direction of the auger flighting as it passes beneath the junction.  A stripper plate is located along each junction, which occurs at the downstream side of the associated corner feed structure, as considered in the direction of rotation of the auger, for stripping material from the outer part of the auger flighting so that it enters the corner feed structure. The stripper plates also serve to support the rear end of the auger.

Abstract: Herein disclosed are a method and an apparatus for supplying an electrical energy to a pair of discharge electrodes  spaced  apart  from  each  other  to  cause  an electric  discharge  in  a  gap  between  the  discharge electrodes.  There  are  firstly  provided  an  alternating voltage  generator  for  generating,  as  the  electrical energy, an alternating voltage having a frequency, and a capacitor  connected  to  the  discharge  electrodes  in series.  The alternating voltage generator has a series resonant  frequency.  The  alternating  voltage  of  the alternating voltage generator is applied to the discharge electrodes through the capacitor.  The frequency of the alternating voltage is set approximately to the series resonant frequency of the alternating voltage generator to cause a dielectric breakdown in and allow an electric discharge current to flow through the gap between the discharge electrodes.   Alternatively,  the  frequency of the alternating voltage may be approximated to the series resonant frequency of the alternating voltage generator, for  example,  from a  frequency higher than  the  series resonant frequency.

Abstract: Cracked naphtha feeds such as FCC naphtha and coker naphtha are upgraded to produce chemical grade BTX (benzene, toluene, xylene with ethylbenzene) while co-poducing a low sulfur gasoline of relatively high octane number. The cracked, sulfur-containing naphtha is processed by hydrodesulfurization followed by treatment over an acidic catalyst, preferably a zeolite such as ZSM-5 or zeolite beta with a hydrogenation component, preferably molybdenum.  The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product to permit a low sulfur gasoline of blending quality to be obtained with the BTX. The BTX can be extracted from the second stage effluent, preferably from a C6 - C8 fraction of this effluent.
