Abstract: An  electrically  conducting  ceramic  composition  is described which can be utilized in an exhaust gas filter. The ceramic composition is compacted into discs or ceramic plates,  are  subsequently  fired  or  sintered  and  then equipped with electrodes.  Electrode leads are attached to the sintered filter discs or plates bearing electrodes which are subsequently connected to a power source. The ceramic filter discs or plates are supported and enclosed in a metallic housing. In another embodiment an insulator ring is placed between the housing and the ceramic filter plate.   The housing enclosing the  ceramic filter or filters,  and equipped with electrodes and appropriate leads,  is  incorporated  in  the  exhaust  system  of  an internal combustion engine.  The ceramic filter is used for trapping combustible carbon particles carried by the exhaust  gas  emanating  from  the  engine.  The  carbon particles collected by the filter can be eliminated by heat generated electrically by means of an electrical current  being  passed  through  the  filter  between  the electrodes when so desired.

Abstract: Disclosed is a method for quantitatively analyzing the amount of a fluorinated ether by-product contained in a crude fluoromethyl-1,1,1,3,3,3-hexafluoro-isopropyl ether, said method comprising the step of: subjecting said crude fluoromethyl-1,1,1,3,3,3-hexafluoroisopropyl ether to gas chromatography using a cross-linked cyanopropylmethylphenyl-silicone capillary column, whereby said fluorinated ether by-product is simultaneously isolated and quantitatively analyzed. With this, it becomes possible to make the content of hydrogen fluoride contained in the sample to an extent that the column is not virtually affected thereby. By the establishment of such an analytical method, the content of impurities in the production process of SEVOFLURANE can be extremely easily monitored. As a result of this, there is provided a remarkable advantage that SEVOFLURANE stable in quality can be obtained.

Abstract: A fluid leak detector mechanism having a main fluid tank an expansion tank for receiving fluid therefrom as the fluid becomes heated and expands and a sensing chamber operatively coupled with the main tank. A signalling mechanism signals to an operator when the level of fluid in the sensing chamber has dropped significantly to alert the operator of the presence of a leak. An oil return valve is operatively coupled between the main tank and the expansion tank and has an open position that allows fluid to flow back to the main tank from the expansion tank and a closed position that blocks oil from flowing from the expansion tank to the main tank. A temperature sensor senses the temperature of fluid. A control mechanism shifts the oil return valve to its open position when the temperature sensor detects a significant drop in fluid temperature thereby allowing the fluid levels to be reset with changes in fluid temperature.

Abstract: A method, a map and an article of manufacture for the exploration of hydrocarbons. In one embodiment of the invention, the method comprises the steps of: accessing 3D seismic data; dividing the data into an array of relativey small three-dimensional cells; determining in each cell the semblance/similarity, the dip and dip azimuth of the seismic traces contained therein; and displaying dip, dip azimuth and the semblance/similarity of each cell in the form of a two-dimensional map. In one embodiment, semblance/similarity is a function of time, the number of seismic traces within the cell, and the apparent dip, and apparent dip azimuth of the traces within the cell; the semblance/similarity of a cell is determined by making a plurality of measurements of the semblance/similarity of the traces within the cell and selecting the largest of the measurements. In addition, the apparent dip and apparent dip azimuth, corresponding to the largest measurement of semblance/similarity in the cell, are deemed to be estimates of the true dip and true dip azimuth of the traces therein. A color map, characterized by hue, saturation and lightness, is used to depict semblance/similarity, true dip azimuth and true dip of each cell; true dip azimuth is mapped onto the hue scale, true dip is mapped onto the saturation scale, and the largest measurement of semblance/similarity is mapped onto the lightness scale of the color map.

Abstract: A control circuit (30) drives the coil (20) of a contactor (10) in response to a control voltage being applied. The control circuit (30) includes a power supply (31) that produces a regulated output voltage from the control voltage. The onset of the regulated output voltage starts a timer (34) which controls the width of pulses produced by a PWM  controller (33). The pulses control a transistor (Q2) that applies the control voltage to the coil (20). Initially the pulses cause a high current to flow through the coil (20) to close the contactor (10) and after an interval of time the timer (34) signals the PWM controller (33) to shorten the pulses which applies lesser current to the coil to keep the contactor closed. A  flyback circuit (36) provides a relatively low reverse voltage drop path in parallel with the coil (20) to maintain the electromagnetic field during the periods between the pulses. When the control voltage is removed to open the contactor (10), the flyback circuit (36) provides a high reverse voltage drop path to promptly dampen the coil current.
