Abstract: INTERMITTENT DROP DETECTING    METHOD AND APPARATUS   ABSTRACT OF THE DISCLOSURE    The present invention provides an accurate method and apparatus for monitoring the drop flow rate from a fluid source.  The method and appara-tus allows for an intermittent drop flow rate by accumulating a weighted drop period rate error factor which is adjusted for each drop period detected.     A drop period window is adjusted by each drop period and is utilized to determine if the current drop period is within the window indicating a nor-mal operation.  Drop periods outside the window cause a factor to be added to the accumulated error factor and drop periods within the window cause a factor to be subtracted from the accumu-lated error factor.  This allows good periods to offset bad periods, so that minor fluctuations in the drop periods during normal operation can be ignored.

Abstract: Title of the Invention:      Generator circuitry Abstract of the Disclosure:        A generator circuitry for connecting a generator to or disconnecting the same from a bus connected to a power supply.  The circuitry comprising a first discon-nector, a breaker and a second disconnector connected in series with one another between the bus and the generator further includes a detecting circuit to detect the generator output and an operating circuit to prohibit an action of opening the second disconnector during detection of the generator output by the detecting circuit.  Since the disconnector is opened in the state where the generator output is not detected, the disconnector is released from the duty to interrupt the charge current flowing to the interelectrode capacitance of the breaker, whereby the use of a small-sized disconnector is rendered possible.

Abstract: ABSTRACT OF THE DISCLOSURE           In a process for applying phosphate coatings to metal surfaces by means of nitrite-accelerated phosphating solutions based on zinc phosphate, the layer weight on iron or steel is reduced and controlled by bringing the metal surfaces in contact with a phosphating solution which addi-tionally contains a nitrobenzenesulfonate and in which the nitrobenzenesulfonate content is such that the weight of the resulting layer is less than 2 g/m2, preferably less than 1.5 g/m .         The content of nitrobenzenesulfonate is greater than 100 mg/liter and that of nitrite should preferably be 10 to 300 mg/liter.  The process according to the invention is applicable both to low zinc and high zinc phosphating solutions.

Abstract: Abstract Method of effecting zoning in wood with the aid of fungus cultures (3).The wood (4) is pretreated by sterilizing it, setting a suitable moisture content and impregnating it.  Impregnation with nutrients ensures that the fungi are sustained by the nutrients added and not by the wood (4). Special patterns can be achieved by using inhibitors.   Pretreated wood is inoculated with one or more fungus cultures and stacked in sandwich fashion.  An interlayer (7) is inserted into the inoculated sandwich to produce the desired zoning pattern.            Incubation is performed with controlled moisture contents and moisture gradients in the wood (4), as well as the composition of the gas phase, and may be carried out as a two-step process.            The method is performed entirely or partially in a closed system.

Abstract: FAST FOOD SERVING TRAY ABSTRACT OF THE DISCLOSURE     A fast food serving tray has the shape of a ship or boat.  It is formed from a partly assembled, knocked down structure formed from an integral, single blank of cardboard or the like.  The pre-assembled arrangement has the sides of the boat structure flat and co-planar with each other.  The side walls are preferably adhesively secured to each other at each end of the tray.  When the side walls are spread apart to form the rounded shape of a ship bowl, a folded bottom wall is brought into a planar relationship forming a reinforcement at the bottom edges of the side walls.  Two generally circular openings are formed on top of the tray together with a relatively large rectangular central opening which is reinforced by a pair of inwardly turned rectangular panels, one at each side of the tray.  The advance in the art is in an improved sturdiness and an ease of assembly.

Abstract: ABSTRACT           This is a method for the complete leaching of the valuable metals in a metal sulphide material which contains copper, zinc, lead, silver and iron by the use of a solution which essentially contains cupric chloride/sulphates.  After the valuable metals have been recovered, the solution is regenerated whereby ferrous chloride and cuprous chloride/sulphate is oxidized to a ferric hydroxide solid and a cupric chloride solution respectively.  The regenerated solution is split into two part-solutions and returned to the process.  One part-solution goes to a metathesis stage where the fresh metal sulphide material is added in large excess with respect to the part-solution's content of copper.  The result is that only the valuable metals like zinc, lead and silver are leached while copper and iron remain in the residue. The other part-solution goes to a leach stage where the residue from the metathesis stage is added.  The ratio between the residue and the solution is about stoichiometric, while the characteristic feature of this stage is how the leach operation is performed.  This results in a well leached residue and an almost completely reduced solution in just one leach stage.  The residue from this stage goes to a third leach stage where all remaining valuable metals are leached completely by the use of chlorine gas/oxygen gas coming from the zinc electrolysis stage.  Iron is precipitated as a hydroxide.  The ratio between the part-solution which goes to the metathesis stage and the part-solution which goes to the leach stage is between 1:1 and 1:100.

Abstract: Abstract A spray unit and process for controlled droplet atomization in which a tangential vortex type fan with wide mouth passes operation from low-to-medium pressures at high volume, passes air through a throat in which controlled droplet atomization of spray material is being achieved prior to emission from the fan in a plane generally parallel to the flow of air. The flow of air sweeps the droplets into a parallel orientation in substantial avoidance of contact of the spray material on the fan parts, throat or mouth thereof and the airflow confines the continuous core of controlled droplets and projects the protected spray toward a target.  The spray units are arranged to permit plural end-to-end adjacent articulated mounting with directional adjustment and flexible conduits for power at the individual units, including spray material delivery and power to lineal actuators and are carriage mounted on wheels for easy movement in the target urea.
