Patent NO-178845-C (NO)
Inventor: SMITH JAMES W
IPC: B01D53/18
Filed: 1992-06-04
Abstract: Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch.

Abstract: A device and method for heating tissue, the device having a catheter shaft (10) for insertion into a patient's body, a chamber formed by a collapsible balloon (8) mounted on the shaft and filled with an electrically conductive fluid (36).  A power supply (50) applies an electrical potential to two or more contacts (22, 24) within the chamber via conductors (18, 20).  The fluid is heated on the basis of I2R losses by a radio frequency electric current flowing between electrodes, and in turn heats the surrounding tissue.  According to the method, the device is inserted into a patient's body, the chamber is filled the fluid, and an electrical potential is applied to the contacts.  The device acts as a temperature source, and a thermistor (26) in the balloon or in contact with tissue responds to the heating effect to control application of the current.

Abstract: A  method,  and  devices  produced  therewith,  for improving  the flatness  of  etched  mirror  facets  of integrated  optic  structures  with  non-planar  stripe waveguides such as ridge or groove diode lasers or passive devices like modulators and switches. The curvature in the mirror  facet  surface, occurring  at  the  edges  of  the waveguide due to topographical,  lithographical and etch process   effects,   that   causes   detrimental   phase distortions, is avoided by widening the waveguide end near the  mirror  surface  thereby  shifting the  curved facet regions away from the light mode region to surface regions where curvature is not critical.

Abstract: METHOD OF FORMING CHAMFERED     SPIGOT END ON PIPE        Abstract A method of forming a chamfered and sealed end on a spiral wound plastic pipe of the type including at least a pair of radially spaced circumferential side walls connected by an intermediate wall which joins generally radially between the side walls and extends in a helical path axially of the pipe.  The method includes determining the desired axial length of the chamfer and removing the intermediate wall which lies between the side walls axially inwardly of the end of the pipe a distance substantially equal to the desired length to define an outwardly open channel between the side walls.  Thereafter one of the side walls is permanently deflected to bring it substantially into engagement with the end of the other of the side walls circumferentially about the pipe to thereby form a chamfer on the end of the pipe.

At the overlap position of the connecting lever and the lock lever, the connecting lever is installed rotatably, one end of the lever being connected to the switch arm and another end of it being connected to the key cylinder of a door or the lock lever.  The switch body is electrically connected to the lock devices of other doors, functions co-operatively motion of the key cylinder or lock lever, and sends out control signal for changing-over the lock devices of the other doors between their locked condition and unlocked condition.  The switch box is installed at a position where it is not overlapped with the lock lever.  The switch box has a circumferential wall protruded integrally from the actuator box and a lid formed separately from the actuator box, and the bottom plate of the actuator box is used simultaneously as an outer wall of the actuator box.  The lid of the actuator box is even with the back plate or higher than the back plate outward.

Title: Method and apparatus for digitally measuring electrical energy consumption
Inventor: LONGINI RICHARD L
IPC: G01R22/00
Filed: 1991-04-11
Granted: 2000-06-06
Abstract: A method and apparatus for digitally measuring electrical energy consumption from a transmission line carrying alternating current. Instead of actually measuring current from a transmission line conductor, the time derivative of the magnetic field induced by current flowing in the conductor is measured thereby obtaining a reading which is proportional to the time derivative of the current flow. Using an appropriate microcomputer, the time derivative of the magnetic field (the magnetic field rate of change) is represented with an algorithmic series for expressing cyclic phenomena, such as the Fourier series of low order. An approximation of the power consumption is then computed by converting the time derivative of the current as expressed in the algorithmic series and a voltage measurement from the conductor mathematically to a power reading, and the power reading is summed to obtain a number value proportional to the energy consumption. Even harmonics and high frequency harmonics may be eliminated in the algorithmic expression of the current derivative to further simplify computer computations and required hardware, and the magnetic rate of change pickup and the voltage pickup are preferably filtered to remove unwanted noise.
