Abstract: BELLOWS PUMP AND PUMPING PLANT FOR OIL-FILLED ELECTRIC CABLES            ABSTRACT OF THE DISCLOSURE:   A pump for pumping insu-lating oil for oil-filled electric cables in which a driven piston is within and spaced from a tubular bellows which is surrounded by an enclosure.   The bellows forms a chamber with the enclosure which contains the cable oil, and the bellows prevents contact of the mechanical parts of the pump, other than an intake valve and a delivery valve, with the cable oil.   Preferably, the space be-tween the piston and the bellows is filled with oil to transmit motion of the piston to the bellows.   The de-livery valve is urged closed by a spring, and the intake valve has an element made of lightweight materials and is held closed by gravity and the cable oil pressure but opens by reason of cable oil pressure reduction and the static pressure of the cable oil fed to the intake valve. Also, a plurality of such pumps operable by a single drive mechanism and a method for evacuating gas from the pump and pump lines in which the delivery valve is operated by a magnetic field external to the valve.

Title: Thermophilic aerobic digestion process for producing animal nutrients and other digested products

Abstract: THERMOPHILIC AEROBIC DIGESTION PROCESS   FOR PRODUCING ANIMAL NUTRIENTS AND OTHER DIGESTED PRODUCTS                   Abstract of the Disclosure Animal waste matter, for example manure produced by hogs, sheep, cattle, chickens and humans is aerobically digested at thermophilic digestion temperatures to produce single cell, proteinaceous material suitable for feeding to animals as part of the animals' nutritive diet.  Animal waste matter is introduced into a digesting zone that is sufficiently insulated to prevent any substantial heat loss from the digesting material during the digestion process.  An oxygenating gas such as air is introduced into the digesting material during all phases of the digestion.          The digesting material is simultaneously vigorously agitated.          The waste material is placed into the digester at ambient tempera-tures and is contacted with the oxygenating gas at a rate and is agitated at a level effective to cause thermogenic microbial digestion of the materials present in the waste matter.  Since the microbial digestion is thermogenic and because the digester is insulated the temperature of the digestion waste material will rise from ambient to thermophilic digestion temperatures.  There-after, the digesting mixture is continuously contacted with the oxygenating gas at a rate and is agitated at a level effective to maintain the thermophilia digestion temperatures for a period of at least four days.          In a broader aspect of the present invention, lignocel-lulosic materials, such as woody plants, as well as biochemically degradable organic materials, such as sewage sludges, organic domestic and industrial wastes and animal, vegetable and fruit processing plant wastes, are digested by the thermophilic micro-organisms present in the foregoing process.  When the foregoing process has reached thermophilic digestion temperatures, ligno-cellulosic material and biodegradable organic wastes can be placed in the digester, preferably in chipped or finely divided form.  The lignin is digested out of the lignocellulosic complex in a period of about four days after placement in the digester, leaving free individual cellulosic cells that can be assimilated by animals.  Likewise, biodegradable materials are digested in a similar amount of time.  Alternatively, lignocellulosic material or biodegradable material in the form of an aqueous slurry can be placed in a digester with a small quantity of animal waste matter or a thermophilic bacterial culture extracted from the fecal matter digestion process described above.  Thereafter the slurry is agitated and aerated in accordance with the foregoing require-ments.  The aqueous slurry will gradually rise to thermophilic digestion temperatures and can be maintained at those temperatures to substantially digest the lignin out of the lignocellulosic complex or to digest the biodegradable material, as the case may be.

Abstract: Abstract of the Disclosure Electrical ballast circuit for operating gaseous dis-charge lamps with direct current.  An inductive reactor coil connected to an alternating current source is connected to a discharge lamp via a full-wave rectifier, and an auxiliary induction coil inductively coupled to the reactor coil is connected to the discharge lamp via another full-wave recti-fier, resulting in the currents from the respective rectifiers to the lamp being out of phase with one another, thereby raising the average current through the lamp and the voltage across the lamp to prevent lamp de-ionization and reduce lamp re-ignition voltage.  Series connected capacitors may be incorporated in the circuit to increase the starting voltage on the lamp if necessary.

Abstract: ABSTRACT OF THE DISCLOSURE A novel process is provided for the preparation of 6,7-dimethoxy-4-amino-2[4-(2-furoyl)-1-piperazinyl]quinazoline.  It includes as a final step, cyclizing methyl-N-(3,4-dimethoxy-6-cyanophenyl)-[4-(2-furoyl)-1-piperazinyl] thioformamidate by heating, together with ammonia, in a polar solvent, in the presence of an alkali metal amide.  The methyl-N-(3,4-dimethoxy-6-cyanophenyl)-[4-(2-furoyl)-1-piperazinyl]thioformamidate is preferably formed by reacting 3,4-dimethoxy-6-[4-(2-furoyl)-1-piperazinyl-thiocarbamido]benzonitrile with methyl chloride.  By this process the quinazoline ring in prazosine is produced within the molecule, rather than in a reaction between two different molecules.

Abstract: REGULATION CIRCUIT                 ABSTRACT OF THE DISCLOSURE    A regulation circuit for providing timing gate signals to the dc power section of a power supply, the regulation circuit utilizing phase angle conduction of a programmable unijunction transistor.  The conduction angle is determined by the occurrence of the cycles of the ac source voltage unless earlier conduction is determined by the sensed dc voltage.  Early conduction occurs when the control voltage to the PUT is allowed to build up beyond a predetermined level when the sensed dc voltage is low.  When the sensed dc voltage is high, an electronic switch closes to discharge a storage element to prevent control voltage build up and, hence, early conduction.  Ac source voltage failure also causes closing of the electronic switch to prevent undue regulation of the power section output at such times and to permit storage capacitors therein to maintain a dc output until source voltage is reestablished.  Soft start elements in the form of long time constant components ensure against the application of peaked voltages during initial start up and in the presence of power surges.
