Abstract: PHASE SYNCHRONIZATION AND CONTROL CIRCUIT     Abstract of the disclosure A circuit for generating control signals used in detecting a power failure in an uninterruptible power supply in which the A. C. signals of the power supply are examined to output a first signal representing the zero crossing of the A. C. signals.  This first signal is used to reset an oscillator whose output clock signals are synchronized with the frequency of the A. C. signals by a phase lock loop circuit.  The clock output of the phase lock loop circuit operates a counter whose output count is used to address a programmable read-only memory which outputs binary bits to a digital-to-analog converter which in turn outputs a full wave rectified sine wave operating at the system frequency which is used as a reference to detect the occurrence of a power failure in the main source of A. C. power signals.  A second control signal is generated indicating a power failure condition which is used in switching an inverter into the power supply for supplying A. C. signals to a load.

Abstract: USE OF MAGNETIC SEPARATION IN SCAVENGING HYDROGEN SULFIDE              Abstract Use of ferri-magnetic reactive iron oxide particles to react hydrogen sulfide in water, hydrocarbon liquids or drilling mud affords quick, effective scavenging of these liquids without accumulation of particulate matter and without wasting the reactive particles.  The reaction product is environmentally safe, so that it may be disposed of on a simple waste heap.     A quantity of the magnetic iron oxide particles, principally a synthetic porous Fe3O4, is suspended in the liquid.  The quantity added is in excess of that required for the reaction with the hydrogen sulfide in order to speed the reaction time and provide a large margin of safety. In use, the reactive iron oxide particles contact and react the hydrogen sulfide, forming a non-magnetic particulate product of reaction.  Thus, if used to scavenge a drilling mud, this contact and reaction occurs as the mud, bearing the drill cutting rises through the drilling formation. By passing the liquid, or at least that portion of it which includes all particulate matter, through a magnetic separator, substantially all, or at least the greater part of, the unreacted oxide particles are recovered for re-use.  Since the unreacted particles are characterized by low remanent magnetism, after the magnetic separation they are readily re-suspended in such liquid.

Abstract: ABSTRACT     The present invention relates to a process for the preparation and preservation of a protein containing mass having 15 to 45 per cent dry-matter obtained from the by-products of slaughter-houses, of the leather processing and food industry and/or from perished farm animals as well as for the preparation of foodstuffs, in the course of which the proteins are subjected to the action of a proteolytic enzyme to obtain a thin protein-containing suspension, adding to the thin suspension gelatinized starch, amylolytic enzymes and a lactic acid producing culture and conducting an anaerobic fermentation which will preserve the protein-containing mass.         The preserved suspension may be used directly for feeding farm animals or it can be transformed into a product suitable for feeding both useful and pet animals by pre-concentrating and mixing it with other foodstuffs, and if required by the addition of fungicides.

Abstract: ABSTRACT A container structure for a dangerous material. An inner container defines a chamber for receiving the dangerous material, an outer container surrounds the inner container, and a fluid chamber is disposed between the inner and outer containers. A body of non flammable liquid is disposed in and completely fills the fluid chamber, and the body of liquid is substantially confined in the fluid chamber. A vent space is disposed between the inner and outer containers in the area above the fluid chamber. The outer container has a bottom wall that is adapted to slidably engage a support surface so that the container structure can slide on the support surface in response to an external impact overcoming its inertia. The inner container is supported essentially by the body of liquid in the fluid chamber, and the body of liquid, being substantially confined in the fluid chamber, distributes impact forces applied to the outer container over a large area of the inner container, thus minimizing damage to the inner container in response to an external impact, and allowing the container structure to slide as a solid body on the support surface in response to an external impact that overcomes its inertia.

Abstract: ABSTRACT          LOW-ENERGY SCANNING TRANSMISSION ELECTRON MICROSCOPE            Low-energy scanning transmission electron microscopy is achieved by using a sharply pointed electrode as a source of electrons having energies less than 10 eV and scanning the electron emitting pointed source across the surface of a self-supported thin film of material to be investigated at an essentially constant distance on the order of nanometers.  The electrons transmitted through the specimen are sensed by a suitable detector and the output signal of the detector is used to control a display unit, such as a CRT display or a plotter.  A scanning signal generating means simultaneously controls both the scanning of the electron emitting point source and the display unit while a separation control unit holds the distance between the point source and surface at a constant value.  The electron emitting point source and associated mechanical drives as well as the specimen film and electron detector are all positioned in a vacuum chamber and isolated from vibration by a damped suspension apparatus.

Abstract: METHOD OF SOMATOTROPIN SOLUBILIZATION AND NATURATION          ABSTRACT A method for solubilization and naturation of somatotropin protein from refractile bodies of host cells is disclosed.  The method embraces the discovery that an aqueous urea or dimethylsulfone solution can be effectively used to solubilize refractile bodies containing such somatotropin protein.  Once solubilized, somatotropin protein can be natured in a urea or dimethylsulfone solution by contacting the solution with a mild oxidizing agent for a time sufficient to result in the formation of the disulfide bonds.  Naturation can efficiently occur even at high protein concentration, in an impure preparation and in the absence of reducing agent.
