Abstract: ROTARY REDUCING KILN SEAL                     ABSTRACT OF THE DISCLOSURE         A seal is disclosed between a stationary hood and an end of a rotary kiln enclosed thereby to prevent entrance of atmospheric air or the exit of process gas.  The seal includes a first annular seal ring on a flange to rotate with the kiln, and a second and nonrotating annular seal ring mounted on an axially movable cylinder arranged around the kiln.  The cylinder is part of a movable assembly that also cooperates with the kiln flange to define an annular chamber encompassing both seal rings and which is filled with a pressurized gas to prevent leakage between the rings.  A thin annular flexible diaphragm around the kiln is circumferentially sealed on one end to the hood and on the other end to the movable cylinder.  The diaphragm is sufficiently flexible to allow the cylinder and attached seal ring to move axially, as the kiln expands, to maintain an effective seal.  A biased linkage pushes the two seal rings relatively together while thermal expansion of the kiln causes the diaphragm to fold and contraction causes the diaphragm to unfold.  The diaphragm is shielded from high temperature kiln gases by an annular flexible wiper that projects inwardly of the movable cylinder to engage a stationary cylinder secured to the hood; and this wiper along with the diaphragm, hood and the stationary cylinder define a chamber filled with relatively cool pressurized gas to cool the diaphragm and resist leakage of high temperature kiln gas into the chamber defined in part by the flexible diaphragm.

Abstract: Abstract An input video signal is fed to a subtractor wherein a difference is taken between the input and the output from a frame memory to provide a difference signal, the magnitude of which is controlled by a magnitude adjuster.  The controlled output is then fed to a threshold circuit, from which a significant difference signal is derived which has a magnitude above a given level.  The significant difference signal is quantized by an encoder into a code having a reduced number of bits as compared with the inputted significant difference signal.  The quantized code is written into a buffer memory, and is read out therefrom at a uniform bit rate to a transmission line.  A sum of a signal indicative of the representative level of the quantized code from the encoder and the output of the frame memory is formed in an adder, and the sum signal is written into the frame memory and read out subsequently or after one frame.  The occupancy of the buffer memory is detected to provide a control over the magnitude adjuster in accordance with the detected value so as to prevent an overflow from the frame memory.  A signal to refresh the frame memory located on the receiving side is transmitted by writing the output of the adder into the buffer memory after switching from the output of the encoder to the output of the adder.

Abstract: RAPID THERMOSETTING OF CARBONACEOUS      FIBERS PRODUCED FROM MESOPHASE PITCH          ABSTRACT OF THE DISCLOSURE     An improved process for producing carbon fibers from pitch which has been transformed, in part, to a liquid crystal or so-called "mesophase" state.  According to the process, the time required to thermoset carbonaceous fibers spun from such pitches can be substantially reduced by treating the fibers with an aqueous chlorine solution before they are processed by heating in an oxygen atmo-sphere.  After the fibers have been thermoset, the infusi-ble fibers are carbonized by heating in an inert atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE      This specification discloses a process and apparatus for the production of a gaseous mixture containing substantial amounts of carbon monoxide and hydrogen.  The process involves three reactant materials comprising (a) a primary fuel of a solid, liquid or gaseous nature, or a mixture of two or more of these, (b) an oxidising gas, usually oxygen, air or oxygen enriched air, and (c) a secondary fuel which is preferably gaseous. These reactant materials are fed continuously into a cylindrically symmetrical combustion chamber in the following sequence of events.  Firstly the oxidising gas and primary fuel are blended together to produce a gas like mixture with the essential property of compressibility.  The gas-like mixture is caused to assume a highly turbulent, compact and self-contained configuration such as by subjecting it to swirl.  In this configuration, the gas-like mixture is ignited to produce a self-contained total combustion zone.  If the primary fuel is a liquid or solid, complete gasification of the mineral free portion of the primary fuel occurs.  The secondary fuel is then mixed with the hot gaseous products of the total combustion zone to react with same to produce substantial amounts of carbon monoxide and hydrogen.  The secondary fuel is preferably introduced into the combustion chamber so that it forms a sheath around the total combustion zone, said sheath being in direct physical contact with the total combustion zone.       The first two sequence of events are achieved by a specially designed burner having primary fuel input means and oxidising gas input means with at least the oxidising gas input means being designed to cause the gas-like mixture to swirl to create the highly turbulent, compact and self-contained configuration.       The specification discloses three forms of apparatus suitable for use with (a) diesel oil as the primary fuel and towns gas as the secondary fuel, (b) liquified petroleum gas as the primary and secondary fuels and (c)a particulate coal/water slurry as the primary fuel and towns gas as the secondary fuel.

Abstract: A B S T R A C T         The invention relates to transversely-excited gas lasers, in which the gas may be at atmospheric or greater pressure and in which the gas is excited by means of a distributed electric discharge between two electrodes.  The electrodes, which are preferably elongate, are such that an initial trigger discharge occurs between minor trigger portions of the electrodes which conditions the discharge gap between the electrodes resulting in a distributed, preferably glow-type discharge, between the major portions of the electrodes causing lasing action in the gas.  The trigger discharge preferably generates electro-magnetic radiation of high intensity to cause volume photo-ionization of the gas.  The electrodes may be composite in form, each having a trigger electrode and a main discharge electrode that are directly electrically connected to each other.

En outre, les parois des trous sont généralement vibrées et sont donc très lisses.  Les alvéoles portés par la surface de la pièce conique servent à assurer une meilleure répartition de l'enduit le long des parois du trou.
