Abstract: ABSTRACT OF THE DISCLOSURE           A thyristor is shunted by a metal oxide varistor in series with switching means which switches abruptly from a normal high-resistance state to a low-resistance, current conducting state when the thyrsitor is subjected to a transient surge of reverse bias voltage the magnitude of which is higher than a predetermined repetitive peak magnitude and is nearly equal to the level at which the thyrsitor turns on in an avalanche breakdown mode.  The voltage-current characteristic of the varistor is coordin-ated with the reverse breakdown characteristic of the thyristor so that surge current will divide therebetween in such proportions that the maximum reverse current flowing through the thyrsitor is lower than a predetermined critical magnitude which can damage the same, whereby the thyristor is able safely to particpate in the surge-energy dissipating process.

Abstract: ABSTRACT OF THE DISCLOSURE     In the synthesis of ammonia with recycle of unreacted nitrogen and hydrogen to the reactor, a purge gas stream is removed from the recycle stream and partially condensed using refrigeration provided by the expansion and subsequent vaporization of the condensate, the gaseous stream from the partial condensation is returned to the reactor and a bleed stream is removed from this gaseous stream and expanded and injected into the expanded condensate.  Accumulation of helium, argon and methane impurities in the reactor can thus be prevented and the expanded vaporized combined condensate and bleed can be recovered at a suitable pressure for use as a fuel gas stream.

Abstract: ABSTRACT        Disclosed herein is a method for determining the fractional flow and corresponding fluid saturation of fluid phases in a subterranean oil-bearing formation containing more than one mobile fluid phase.  A carrier fluid containing a plurality of precursors is injected into the formation by means of a well.  The carrier fluid is substantially insoluble in a first fluid phase and miscible with a second fluid phase in the formation.  Each of the precursors has a distinct partition coefficient between the carrier fluid and the first fluid phase which differs from the partition coefficients of the other precursors.  Each precursor forms at least one tracer product within the formation with each tracer having a partition coefficient between the carrier fluid and the first fluid phase which differs from that of its corresponding precursor.  After measurable quantities of tracer are formed by the precursor, the carrier fluid tracer solution is displaced through the formation to a point of detection which is preferably the injection well.  The relation between fractional flow and saturation of the fluids in the formation can be determined by applying the principles of chromatography as applied to the movement of the precursors through a porous medium contain-ing two mobile fluid phases.

Abstract: Abstract of the Disclosure A device for detecting a key switch operation capable of detecting an operating state of a plurality of key switches which are commonly connected with respect to each row line (block line) at one terminal thereof and commonly connected with respect to each column line at the other terminal thereof, thereby constituting a switch matrix.  If a signal is provided on all column lines, the signal is transmitted to a block line through a key switch which is in operation and thereby a block including the key switch in operation is detected.  A signal is then supplied from the detected block line to a column line only through the key switch in operation in the detected block.  The position of the key switch in operation is known by detecting the column line on which the signal arrives. According to an embodiment of the invention, capacitance elements are provided both on the block lines and on the column lines for effecting delivery of the signal by charging and discharging of these capacitance elements.  There is also disclosed a construction in which detected blocks are once stored in a memory and positions of key switches in operation in the detected blocks are detected and stored block by block.  The stored blocks and key switch positions are codified to produce key codes identifying the key switches in operation.

Abstract: ABSTRACT           Nontoxic polymeric plastic medical implants for endosteal and periosteal applications such as filling bone defects, replacing entire bony parts, and tooth replacement either immediately after extraction or subsequent to healing, and a method of fabricating such implants to produce a porous surface having a predetermined pore size, pore depth, and degree of porosity.  The method of fabrication of the porous portion of the implant involves adding sodium chloride crystals or other nontoxic leachable substance of controlled particle size corresponding to the desired pore size to a powdered polymer-liquid monomer mixture in relative amounts corresponding to the desired degree of porosity.  After heat poly-merization without an initiator, followed by abrasive removal of the resulting surface skin, the salt is leached from the plastic to provide said porosity.  To obtain bone ingrowth in the case of intraosseous implantation, the pore size must be 200-400 microns, whereas pore size for soft tissue ingrowth should be 50-150 microns.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to an improved circuit used to supply operating power to fluorescent lamps.  Conventional ballasts for fluorescent lamps are large, heavy, expensive, and electrically inefficient, wasting a substantial percentage of the power supplied to the lamp installation.  The present invention eliminates the need for a ballast and offers a unique use for a switching arrangement.  According to the invention, there is provided a circuit employing an oscillator having a feedback loop for supplying operating current at a frequency in the range 20-25 killohertz to a pair of fluorescent lamps connected in series.  The heater filament of the first lamp is made a series element in the feedback loop of the oscillator, so that removal of that lamp disables the oscillator.  Switching means is provided to bypass the open socket terminals of the second lamp when it is removed from its sockets, permitting power to continue to be supplied to the first lamp.

Abstract: ABSTRACT OF THE DISCLOSURE:       The invention relates to the manufacture of electric lamps containing fluorine in their gas fill.  Fluorine can be accurately and conveniently introduced into an electric lamp envelope in the form of a fluorocarbon polymer.  If a soluble fluorocarbon polymer, such as a degraded PTFE, is dissolved in a suitable solvent, for example a fluorine-substituted hydrocarbon or halocarbon solvent, the resulting solution can be metered with great accuracy into the lamp envelope and the solvent subsequently evaporated.  The invention avoids the difficulties otherwise inherent in dispensing accurate quantities of an extremely reactive gaseous material.

Abstract: ABSTRACT OF THE DISCLOSURE       A strip which will form a rigid shoe stiffener, such as a shoe shank, is applied to the surface of a shoe to be stiffened, such as the bottom of an insole.  The shank strip is flexible and includes a carrier sleeve which contains a plu-rality of fiberglass strands in a thermosetting plastic matrix. After the shank strip is in place on the insole, the matrix is activated by exposing it to an external stimulus such as heat or radiation.  Heat can be applied locally to the shank strip and curing takes place directly on the insole bottom.  The thermosetting resin can polymerize with or without an exother-mic reaction.  In one embodiment of the invention, the carrier sleeve is formed in a manner which provides control over the shape of the cured stiffener as well as a means to facilitate handling of the shank strip.  In another embodiment sufficient heat is developed from exothermic heat or from the energy source and directed to melt the carrier sleeve to fuse it with the resin and to effect a bond to the insole for forming a uni-tary and rigid shank attached firmly to the insolebottom.  The shank strip may be cut from a "rope" which may be wound onto a reel for storage and to facilitate continuous paying out of the rope to enable a shank length to be severed and applied to the insole bottom.
