Abstract: PCT No. PCT/JP79/00083 Sec. 371 Date Dec. 5, 1979 Sec. 102(e) Date Dec. 5, 1979 PCT Filed Apr. 4, 1979 PCT Pub. No. WO79/00937 PCT Pub. Date Nov. 15, 1979.An intermediate frequency detection circuit of a superheterodyne type radio receiver is disclosure which includes a logic circuit inputted with a signal indicating the level of an intermediate frequency output and a signal indicating the level of a high frequency output of the receiver. This logic circuit generates a indication of the reception of a broadcasting wave when the intermediate frequency output is high and the high frequency output is low. This intermediate frequency detection circuit avoids the erroneous detection due to spurious signals and likewise renders the pulse width of the detection signal approximately constant thus making this circuit suitable for use with automatic channel selection.

Abstract: An activated sludge marine sewage disposal apparatus includes an aeration chamber immediately adjacent to a flooded settling tank, rising above a disinfectant chamber and a holding chamber disposed around the lower part of the tank. Flow from the aeration chamber to the settling tank is through a port in the common wall between the aeration chamber and settling tank, and up inside a pond separated from the rest of the tank by a downwardly flaring baffle of skirt depending from the top of the tank. A single shimmer at the center of the area at the top of the pond picks up floating solids and returns them to the top of the aeration chamber. A vent disposed directly over the shimmer continuously draws off air and gas to the aeration chamber. A sludge return line picks up heavy solids for the bottom of the tank and returns them to the top of the aeration chamber through a riser located in the aeration chamber. Liquid in the settling tank flows out through a submerged perforated pipe into a standpipe in the aeration chamber, with is located centrally in the aeration chamber, and overflows through an inverted U tube, vented to the aeration chamber, the tube connecting to a downcomer sending the liquid back through the common wall to the disinfectant compartment. When sufficient volume of fluid accumulates in the disinfectant compartment, it overflows into a holding tank, from which it emerges via a port.

Abstract: Mine run coal is pulverized and the extended surfaces of the coal particles are rendered hydrophobic and oilophilic by a chemical bonding and graft polymerization reaction with a water insoluble organic polymerizable monomer under peroxidation influence in a predominantly water reaction medium. The mineral ash present in the coal and particularly the iron pyrites remains hydrophilic and is separated from the polymeric organic surface bonded coal product in a water washing step wherein the washed coal floats on and is recovered from the water phase and the ash is removed with the separated wash water in a critical wash step. Excess water is removed from the beneficiated hydrophobic surface-altered coal product mechanically. The hydrophobic and oilophilic organic polymeric surface bonded coating about the coal particles is fortified by inclusion of additional unbound free fatty acids by further small additions thereof. The carboxylic acid groups present in the coal-oil product are thereafter converted to a metal soap. The beneficiated coal product can be used "dry," or additional quantities of a liquid hydrocarbon fuel can be incorporated with the "dry" beneficiated coal product to produce a flowable fluid or liquid coal product having the rheological property of marked thixotropy. Introduction of this physically induced property into the liquid coal-oil-mixture prevents settling out of the heavier coal particles from the relatively ash-free fluid fuel composition under extended storage periods.

Abstract: A valve insert is designed for use in valve casings for making up air valves which may be controlled by air under pressure or by a mechanical system and which are normally open or closed. The valve insert is made up of a housing, which is open at its two ends and has two groups of outwardly running openings, which are separated from each other by an outer gasket ring. The valve further has a spool with sealing rings. One end the spool has a hook having a neck part which is spaced from the spool axis and a hook end which is normal to the neck part. The end part of the hook extends past the axis of the spool a distance which is at least equal to the distance of the neck part of the hook from the axis of the spool. The diameter of the hook end is somewhat smaller than the distance between the hook end and the end face of the spool. The sealing rings are so placed that, on operation of the valve and motion of the spool, one inner sealing ring is moved over one group of openings.

Abstract: A positioning control system wherein variations in the robot coasting distance are substantially eliminated by stopping the command pulse signals simultaneously with a generation of the origin pulse signal from the incremental encoder. The deviation between the final robot position and the origin is minimized by driving the motor in its backward direction to back up the robot by an amount approximately equal to the coasting distance. The robot moving distance during the time period from the beginning of origin return operation (i.e., backup) to a generation of the first spike in the origin pulse signal after beginning backup to the above first stoppage of the robot is found. If the found distance is different from the coasting distance then this difference is handled as an error. In one aspect of the present invention, the number of spikes appearing in the output pulse signal from the incremental encoder can be easily increased as necessary to thereby improve the resolution power of the incremental encoder. Further, much more precise positioning control can be realized by synchronizing the output pulse signal of the incremental encoder with the clock signal of the microcomputer.

Abstract: A respirator comprises a respirator which includes a closed circulation circuit for breathing gas which has in any phase of the breathing process a slight overpressure compared to the ambient atmosphere. The excess pressure in the circuit is maintained by a combination of lung controlled amount of air and an amount of oxygen added independent of the oxygen content in the expiration air. Leakages are compensated to maintain proper breathing. The lung controlled amount of equalizing air prevents the possibility of hazardous outflow in case of leakages. The switchable connection is maintained between the compressed air line and the lung control valve with the oxygen line to ensure the supply of proper circulating air even in a failure of the electrical control of the oxygen supply. For the ratio of the two pressure gas supplies to each other it was expedient to select a ratio of air to oxygen of about 1:4. For a 2 hour apparatus, a 1.2 liter bottle with 200 bar filling pressure can be selected for the compressed oxygen, so that an oxygen supply of 240 liters is obtained, and a content of 0.3 liters at 200 bar can be selected for the compressed air bottle, which yields an air supply of 60 liters. The total breathing gas supply is then 300 liters which is sufficient for an operating time of 2 hours.

<??>The inlet valve is closed during the inlet stroke, so that expansion of the air in the cylinder at full load subsequent to closing the valve is effected to or beneath the pressure in the exhaust system.
