Abstract: ABSTRACT          "Transmission system for the transmission of binary data symbols".     A transmission system for transmitting binary data symbols.          For the transmission of data symbols via systems which, the physical transmission medium included, are not suitable, or are poorly suitable for the transmission of low frequencies it is known to use bi-phase modulation. This mehtod is however not optimal as regards the signal-to-noise ratio and the intersymbol interference.           A transmission system is described in which an optimum detection is enabled through the use of bi-phase encoding of the binary data symbols and special filter means, which detection is highly independent of the frequency response of the constituent parts of the transmission system and/or the physical transmission medium for low frequencies.           This system may be used in optical communication systems as well as in systems for digital transmission via cables, the undisturbed, simultaneous transmission of an independent base-band signal being possible.

Abstract: TEMPERATURE-ACTUATED FLOW CONTROL DEVICE              ABSTRACT OF THE DISCLOSURE         A temperature-actuated flow control device has a fluid inlet connected to an exhaust line with a con-trol chamber located therebetween. The control chamber has a free-floating bi-metallic circular element which is flexed in response to temperature changes between a first  position stopping flow between the inlet and the exhaust line and a second position opening the flow therebetween. This flow control device, when adapted-to a gas sampling system, allows the bi-metallic ele-ment remain in a first position at normal operating temperatures to permit the continuous sampling of the sample gas. Whenever the temperature falls below the dew point of the sample gas, the  bi-metallic element re-turns to its second position to stop the sampling of sample gas by the system to prevent condensation in the system.

Abstract: Abstract of the Disclosure A continuous process is disclosed for the recovery of an aluminum alloy from aluminum scrap containing more than one alloy.  The recovery is made in a manner which will conserve energy.  The process comprises providing a feed stock containing at least two components therein comprised of different aluminum alloys, the components having at least parts thereof joined to each other.  The feed stock is treated to cause the joined components to become detached from each other.   One of the detached components is separated from the remainder of the feedstock, melted and thereafter continuously cast without substantially upgrading the composition thereof to provide a cast alloy having a composition substantially the same as that from which the separated component was fabricated.  The treating may be accomplished by heating the feedstock to a temperature sufficiently high to render fracture sensitive the component having the lowest incipient melting temperature.

Abstract: Abstract of the Disclosure A new reactor for the production of carbon black, a new method for the production of carbon black, and a new carbon black are disclosed. The carbon blacks are characterized by a surface area preferably in the range of 70 to 150 m2/g and "G" values of either less than 1.20 or greater than 1.85, corresponding to very narrow or very broad aggregate size distributions, respectively. The reactor is preferably for axial flow of combustion gases and is characterized by serial arrangement of a cylindrical combustion zone, a frustoconical converging zone, a throat, an abrupt diverging zone and a cylindrical pyrolysis zone. In certain aspects of the invention, the combustion gases are formed by combusting low BTU fuel and forcing these gases through the throat at a velocity approaching Mach 1. In one method of carbon black production, the feedstock is introduced into the converging zone. In another method, it is introduced as a spray. In other methods, the feedstock is introduced with upstream or downstream velocity components.

Abstract: Abstract A forced encapsulation system that can be advantageously used to encapsulate cable splices, e.g., multiconductor communications cables.  Containment means are formed around a substrate comprising part of at least one cable, and secured to the cable, thereby forming an enclosure into which liquid encapsulant can be introduced and in which the encapsulant can be pressurized and maintained at pressure above ambient pressure.  In a preferred embodiment, the containment means comprise a containment bag formed in situ from an elastomer sheet and sealed to the cable sheaths, with a reenforcing outer enclosure surrounding the containment bag.  Pressurizing the liquid encapsulant leads to thorough penetration of the encapsulant into the splice work and cable ends and to intimate-contact between the cured encapsulant and the surfaces within the enclosure, including surfaces with which the encapsulant does not form an adhesive bond, resulting in improved gasketing around conductors, thereby reducing the possibility of water-caused splice damage.
