Title: Intrinsically safe battery pack e g for a miner's lamp
Inventor: GENTRY KENNETH ROY
IPC: H02H9/02
Filed: 1985-01-08
Abstract: © An intrinsically safe battery pack arrangement for electrically powering electrical devices is disclosed. The power pack has a device for electronically determining a short in a cable or device and switching off the voltage to the power pack. The electronic device includes a transisterized circuit for sensing and controlling currentthrough the cable. When the currentex- ceeds a predetermined maximum, the circuit limits the current in the cable to a maximum value. The circuit is latched in the off position when the short is present for an extended time and the circuit may be reset after the short is removed and the problem corrected. This form of circuitry in power packs for use with mining equipment such as lamps, provides a unit which will not cause hazardous sparks when shorted thereby constituting an intrinsically safe device for use in mines.

Title: Sewage treatment process
Inventor: ITOH YUICHIRO
IPC: C02F1/24
Filed: 1985-07-24
Abstract: Coal pulverized by a mill or crusher is used as a floating agent which is charged into a floating machine, together with wastewater, for example, from a wastewater treatment facility or homes which produce organic substances such as human wastes. The pulverized coal and wastewater are mixed and uniformly stirred by a stirrer in the form of an impeller or a cyclone separator while being aerated. The produced floating floc is discharged from an upper portion of a first floating machine, whereas sedimented materials are discharged from a lower portion of the first floating machine. The same process is repeated in other floating machines connected in series to the above-described first floating machine. The collected floating flocs are dewatered to produce solid cakes which are used as a fuel. The water which has been extracted to form the solid cake, is purified and discharged.
