4985682 LEAK MONITOR FOR SECONDARY CONTAINMENT. LIQUID STORED IN UNDERGROUND STORAGE TANKS
OF
Daniel Boryta assigned to Leak Sensors Inc A system for monitoring the continuity and potential rate of leakage of an underground tank hole liner formed of a sheet of electrically insulating polymeric material in which a standard current measurement is made of a circuit comprising a standard electrode in the form of a container of electrically insulating material having a small hole in a side thereof and containing an electrically conductive fluid connected to an injection electrode through a current source, the electrodes being immersed in a conductive fluid in the bottom of the tank hole to provide a calibrated liner leakage value, and such measurement is compared with the current provided by a circuit comprising the injection electrode connected to a ground electrode through the current source. If the latter current measurement is less than the standard, the area of the liner tested is considered to meet specifications as regards leakage since the total area of leaks, if any, is no greater than the area of the hole in the standard electrode, where as if the current exceeds the standard value, the liner is deemed not to meet specifications.
4986141 TAPE DRIVE WITH SELFEXPANDING COILS FOR SLUDGE COLLECTOR
Pulleys guide the intermediate section of the tape from the first reel to the second reel for moving a sludge collector. When the drum is rotated in a first rotary direction, the first coil tends to selfunwind from the first reel and the second coil is wound up on the second reel to move the intermediate section of the tape and the sludge collector. Upon rotation of the drum in a second rotary direction, the second coil tends to selfunwind from the second reel to apply tension to the tape and the first coil is wound up on the first reel to move the intermediate section of the tape and the sludge collector.
4986268 METHOD AND APPARATUS FOR CONTROLLING AN ARTIFICIAL RESPIRATOR Fleur Tehrani An apparatus for automatically controlling an artificial respirator includes sensors for receiving the exhaust gas from a patient and providing data signals corresponding to the concentration of the carbon dioxide and oxygen in the gas. The data signals are provided to a microcomputer which, together with data representing at least the patient's lung elastance factor, air viscosity factor in the lungs and barometric pressure, and when the patient is in exercise, metabolic rate ratio, determines the total ventilation and frequency for the patient's next breath and provides data output signals corresponding thereto. The data output signals from the microcomputer are provided, in analog form, to a signal generator and timing control circuit. This circuit provides output pulses which control the respirator and control valves between the respirator and the sensors.
4986905
Charles Meurer assigned to Baker Hughes Incorporated Apparatus for taking up and paying out first and second ends of an endless loop of tape that has an intermediate section. A first reel connected to the first end carries a first coil of the tape. The first coil extends from the first reel and is normally self-expanding and unwinding so as to unwind itself from the first reel. A second reel is connected to the second end for carrying a second coil of the tape. The second coil extends from the second reel and is normally selfexpanding so as to unwind itself from the second reel. A drum supports both of the first and second reels for rotation in the same direction.
DISTRIBUTION CONTROL SYSTEM FOR RECYCLING TREATED SEWAGE WATER FOR IRRIGATION Rocky R White The present invention is a self-contained residential and commercial treatment system which is capable of purifying waste water and then distributing the purified water by means of a sprinkler system or a drip feed irrigation system or of recycling the purified water in some manner.
