Abstract: CIRCUIT FOR CONVERTING SINGLE-ENDED INPUT SIGNALS TO A          PAIR OF DIFFERENTIAL OUTPUT SIGNALS     ABSTRACT OF THE DISCLOSURE     A circuit that is particularly adapted to convert a single-ended input signal to a pair of differential output signals.  First and second series circuits are connected in parallel, the first series circuit being formed of first and second diodes and the second series circuit being formed of a third diode connected with the collector-emitter circuit of a transistor.  The base electrode of the transistor is connected to the junction defined by the first and second diodes such that the base-emitter circuit thereof is in parallel arrange-ment with the second diode.  A current source is connected to the parallel-connected series circuits so as to supply currents thereto.  An input signal is supplied to the junction defined by the first and second diodes; and first and second outputs are coupled to this junction and to the collector electrode of the transistor, respectively, for providing differential output signal currents that are a function of the supplied signal.          This circuit can be connected to a differential amplifier to supply differential signals to the latter, whereby a gain con-trolled amplification of the original single-ended input signal can be attained.       -i-

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a method of treating the components of a gaseous fuel mixture to obtain a predetermined mass ratio of the gaseous components for use in a metallurgical melting furnace.  Two streams of gaseous fuel components are temperature equalized in a heat exchanger, pressure equalized by pressure balancing regulators, and mixed together by a mixing valve which controls only the volume flow rates of the two streams.  The resulting gaseous fuel mixture has a predetermined oxygen to fuel mass ratio, which is easily maintained near stoichiometric composition and which when combusted, supplies a hot gaseous blast of predetermined composition.  When air and a liquefied fuel such as liquid propane are the fuel components, the liquefied fuel is vaporized prior to heat equalizing, pressure equalizing, and mixing.  When a gaseous fuel such as natural gas is one of the fuel components, no vaporization or dilution is required.  The resulting carefully controlled gaseous fuel mixture is used to provide both the heat and the required atmosphere of con-trolled chemical composition  in a copper melting furnace.

Abstract: ABSTRACT            In the manufacture of a monolithic LED array, in which portions of the array are electrically isolated from one another by channels cut or etched through the slice of n-type material, the channels are filled with a glass frit which is bonded to the semi-conductor material on each side of the channel, to give a robust construction.  A suspension of glass particles in a liquid medium is introduced into the channels, then the liquid is removed and the glass powder is sintered;  the channels may be of uniform width, or may consist of a wide portion, formed first from the back of the slice, and a narrower, shallow portion formed subsequently from the front of the slice to meet the wide portion, to give high resolution.  The glass suspension may be introduced into the channels by spreading or spinning over the slice surface, or by electrophoretic deposition and/or capillary action.

Abstract: SYSTEM FOR SECURING POSTAGE PRINTING TRANSACTIONS     ABSTRACT OF THE DISCLOSURE       A postage meter includes printing and accounting stations-interconnected through an insecure communications link.  Each time the meter is tripped, a number generator at the printing station is activated to generate a number signal which is encrypted to provide an unpredictable result. The number signal is also transmitted to the accounting station.  At the accounting station the postage to be printed is accounted for and the number signal is encrypted to provide a reply signal.  The reply signal is transmitted to the printing station where a comparator compares it with the encryption result generated at the printing station.          An equality of the encryption result and the reply signal indicate-that the postage to be printed has been accounted for and the printer is activated.

Abstract: ABSTRACT OF THE DISCLOSURE In the railroad propulsion vehicle described, the traction forces axe transmitted from the bogies to the vehicle body supported thereon at a height h above the upper rail edges.  The body support means are each arranged at a distance x from the transverse center plane of the bogie between the latter plane and the adjacent body end in order to balance out the tilting-up moment exerted on the leading bogie.  The distances h and x are adjusted to a desired distribution of the axle pressures A1 to A4 or the deviations Q1 to Q4 from a mean axle pressure value.  On the basis of the chosen distribution, the values x and h can be calculated in a simple manner.         The distribution of the deviations Q is, for instance, chosen so that all three leading axles are equally load-relieved and the fourth axle is loaded accordingly.          According to another embodiment, the first axle is less load-relieved by .DELTA. Q than the second axle, and the latter is load-relieved the same as the third axle.  This takes into consideration that the first axle encounters a some-what lower friction coefficient than the following axles.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a new and novel process of producing a vinyl resin latex by the emulsion polymerization technique comprising adding to the latex with thorough mixing an aqueous solution of an electrolyte, such as, for example, ammonium carbon-ate, and removing a part of the water by filtration or centrifuging, and the like; to produce friable aggre-gates of individual spheres of polymer particles.  Thereafter, the friable aggregates of polymer particles are separated into individual spheres of polymer parti-cles by simple light rubbing or crushing and dried.  In many cases, the separation can be accomplished by simple mixing of the resin with plasticizer during the plasti-sol preparation.  Thus the spray drying and the subse-quent grinding steps are eliminated producing a superior product for plastisols.
