Abstract: Process for the production of 4-substituted acetoacetic acid derivatives. An acetoacetic acid derivative having the formula: <IMAGE>   wherein R is alkoxy having 1 to 6 C atoms, phenoxy, -NR'2, wherein R' is alkyl having 1 to 6 C atoms or aryl, or NR'2, which is azetidine, pyrrolidine or piperidine, is treated with a secondary amine at an elevated temperature and in the presence of an organic solvent. The water formed is separated. The intermediate is converted into the corresponding 3-enamine carboxylic acid derivative. The derivative is converted by treatment with sodium amide in liquid ammonia into the corresponding sodium salt. The sodium salt is converted by treatment with a halogen compound having the formula R1CH2X or R1R2CHX, wherein R1 and R2 each are alkyl, alkenyl, alkinyl or aryl and X is chlorine, bromine or iodide, into the corresponding 4-substituted enamino derivative. The derivative is hydrolyzed into the 4-substituted acetoacetic acid derivative.

Abstract: In the particular embodiments of the waste water treatment system described in the specification, a waste water treatment basin has spaced-apart, moving aerator chains extending across the basin in a direction transverse to the flow of waste water through the basin. When an aerator chain is provided with air, bottom aerators suspended from the chain adjacent to the bottom of the basin move with respect to the basin to mix sludge collected on the basin with the waste water and to supply air to the waste water. A control system supplies air selectively to the aerator chains to provide zones of full aeration and intermediate zones with little or no aeration and the selection of the aerator chains is changed periodically in a progressive manner along the basin so that the zones move progressively through the basin. As a result, sufficient air is supplied to the waste water in the basin for purification of the waste water and to maintain sludge in suspension as required in the waste water at minimum expense of energy. In addition, the oxygen potential of the waste water in the zones is controlled so that successive reactions relating to the purification process are accomplished in successive zones, for example, including nitrification of the waste water in zones having a relatively high oxygen potential and denitrification in adjacent zones having relatively low oxygen potential. Phosphorus removal is accomplished in a similar manner.

Abstract: A subsurface formation surrounding a deviated borehole and having original in-situ stresses that favor the propagation of a vertical fracture is penetrated by a cased borehole. The casing is perforated at a pair of spaced-apart intervals to form a pair of sets of perforations. Fracturing fluid is initially pumped down said cased borehole and out one of said sets of perforations to form a first fracture that is oriented in a direction perpendicular to the direction of the least principal in-situ horizontal stress. The propagation of this first vertical fracture changes the in-situ stresses so as to favor the propagation of a second vertical fracture. This is oriented in a direction parallel to the direction of the least principal in-situ horizontal stress. Thereafter, while maintaining pressure in the first vertical fracture, fracturing fluid is pumped down said cased borehole and out of the other of said sets of perforations to form such a second vertical fracture which will now link naturally occurring fractures in the formation to the deviated wellbore.

Abstract: The time base control circuit for a waveform sampling system, is of the type which samples an input waveform, converts the waveform sample into representative digital data and stores that digital data in an addressable memory, the timing of waveform sampling being controlled by a sampling control system. A sampling bridge (10) of the digitizer samples the input signal (Vin) when it is strobed with short pulses produced by a strobe generator (52) in response to a square wave output signal from a triggered programmable-skew oscillator (54) the frequency of which is controlled by the microprocessor (46). The output of the oscillator (54) is triggered by the trigger generator (55) which detects a triggering event, such as a zero crossing in the input (Vin). The time base curcuit permits the sampling system to operate in an equivalent time mode in repetitive waveform sections are sampled at progressively skewed sampling intervals.
