Abstract: This invention provides a process for the biotreatment of effluent from waste gas scrubbing systems of hydrocarbon processing facilities and for the biotreatment of sulfide- and ammonia-containing wastewater streams from other sources. Sulfides are minimized by bacteria cultures, particularly Thiobacillus. COD, TKN and BOD are concurrently minimized by co-cultures of the bacteria with various heterotrophs. In a version of the process, the co-cultures of the bacteria with various heterotrophs are also capable of performing nitrification, without application of nitrifiers. Acclimation of the heterotrophs to the species to be removed is accomplished by biological acclimation and enrichment reactors which reduce mycell toxicity to the heterotrophs. To control pH of the heterotrophic reaction with sulfides, magnesium oxide (MgO) and caustic are used separately or in combination.

Abstract: An alarm system, comprising a smoke detector, a smoke detector output relay, a recording switch, a microphone, a digital recording and a play back device, a timer/pulse generator, a pulse counter, a number of speakers, an amplifier and an alarm tone generator, and the method of operation of the alarm system are presented. The smoke detector output relay activates a printed circuit that is powered off the smoke detector at two different points. The recording switch, when activated, allows a voice message to be recorded through the microphone on a digital recording and play back device. The timer/pulse generator starts when activated by the smoke detector output relay. The timer/pulse generator then sends timed pulses to the pulse counter that controls output of the digital recording and play back device, i.e. a verbal message, and of the alarm tone generator. The controlled output of the digital recording and play back device and of the alarm tone generator is then sent to the amplifier.

Abstract: This invention features a small-enveloped (with an outside diameter of at least approximately 38 mm), single-acting, hydraulically-operated, reciprocating, deep-well, fluid-extraction pump, operable in non-straight and angular wells, and its mode of operation. The hydraulically-operated, deep-well pump, in addition to having an above-ground installation of its motor-fluid generator and of its control valving, comprises a compound, stepped piston that is reciprocably mounted within a cylinder which in turn is divided into individual pressure chambers. Hydrostatic pressure created by a hydraulic pump is selectively directed to two outlet ports to produce an overpressure in one of the outlet ports at any given instant. The overpressure in each outlet port leads to creation of overpressure in one or more pressure chambers. Imbalances in pressure among the pressure chambers result in movement of the compound, stepped piston and extraction of hydraulic-well fluid by the compound, stepped piston.

Abstract: This invention presents an air condition utility system for providing air condition to sets of buildings, with each building having a number of amended air conditioning systems, by repeatedly circulating a refrigerant in a closed loop. Each station is connected to an assigned set of buildings of a district by high-pressure lines and low-pressure lines. High-pressure lines are used to transfer the refrigerant, in a liquid stage, from a station to each building that is served by the station. Upon providing air condition to a building, the refrigerant loses pressure and returns in a partial-gas partial-liquid stage through downwardly-sloped low-pressure lines from the building to the station. In the station, the refrigerant is pressurized by passing through a number of compressor units and again leaves the station in a liquid form through the high-pressure lines.
