Abstract: Abstract of the Disclosure This invention relates to a process for heating nongaseous carbonaceous material by introducing tangentially a first stream containing a nongaseous carbonaceous material and carbon monoxide into a reaction zone; simultaneously and separately introducing a second stream containing oxygen into the reaction zone in such manner that the oxygen enters the reaction zone away from the wall thereof and reacts with the first stream thereby producing a gaseous product and heating the nongaseous carbonaceous material; forming an outer spiralling vortex within the reaction zone to cause sub-stantial separation of gases, including the gaseous product, from the non-gaseous carbonaceous material; removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous carbonaceous material before a major portion of the gaseous product can react with the nongaseous carbonaceous material; and removing a fourth stream con-taining the nongaseous carbonaceous material from the reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE     A dirty gas inlet configuration for a cyclone-type particulate matter gas separator device has two annular concen-trically disposed converging dirty gas channels.  The outer annular channel has a plurality of gas flow directing vanes dis-posed therein to impart a spinning or whirling motion to a dirty gas stream passing into the separator device through the outer annular channel from outside the separator device.  The inner annular channel has an adjustable dirty gas inlet for varying the volume rate of flow of dirty gas passing into the separator device through the inner annular channel from outside the sepa-rator device.  The dirty gas streams exiting the outer and inner annular converging channels are mixed together in an annular mixing chamber located downstream from and coaxially disposed with the outer and inner annular channels.  While mixing to-gether, the whirling gas stream from the outer channel imparts a whirling motion to the dirty gas stream from the inner annular channel.  The mixed whirling gas stream then exits the annular mixing chamber and moves downstream in the gas separator device for further processing to separate particulates therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE           A water dispenser for livestock, particularly pigs, has a hollow mouthpiece activated by the animal.  The mouth-piece projects from a casing and is tiltable relative to the casing axis.  Water released from a valve passes into the mouthpiece, whose rear portion co-operates with an axially-movable, spring-loaded valve plunger in order to regulate the water supply.  The rear portion of the mouthpiece and the plunger foot are each internally provided at mutually-opposite points with a disc, radial to the points.  The discs are of identical or nearly identical diameter, with tilting of the mouthpiece causing movement of the disc of the plunger foot so as to activate the valve plunger.  Both discs are surrounded by a common guide-ring, and an annular seal located on the mouthpiece is mounted between two ring inserts which have an inwardly-directed collar.

Abstract: ABSTRACT         A top-to-bottom mixer suitable for extending through a small opening in a closed top drum for mixing liquid.  The mixer has a tube for extending axially downward into the drum.   Since closed top drums in commerce have a maximum top opening of 2" pipe size, this mixer is additionally unique in that it will insert into this small opening.         The tube has a circumferentially located opening adjacent the lower end and a shaft extending concentrically into the tube, connected to a turbine at the bottom of the tube or other means for causing downflow.  Four spaced inlet openings at the top are provided in the tube adjacent the upper end.          The motor drive, connected to the shaft, rotates the shaft, creating a steady suction effect at the upper intake ports that draw liquid into the inlet openings adjacent the top of the tube and discharge it tangentially through the discharge opening at the lower end of the tube, thereby circulating the liquid in from the top to the bottom of the drum and discharging the liquid at the bottom in a jet-like, high-pressure blast that loosens, suspends and sets in motion, packed and settled mass, such as settled sludge.

Abstract: ABSTRACT OF THE DISCLOSURE          In an apparatus for automatically maintaining a transducing head assembly on the proper track, which is particularly adapted for a helical scan recording and/or reproducing apparatus capable of providing special motion effects, movable head automatic position acquisi-tion circuit and method is disclosed.  The apparatus is of the type which utilizes transverse positioning of the transducing head assembly to accurately follow a track during reproducing, and at the completion of the track, to properly position the head in postion to either play the next adjacent successive track, replay the same track or replay another track so that the appropriate special motion effect is achieved.  In the still frame motion mode of operation, the head is normally reset to rescan one or more tracks repetitively by a head tracking servo.          A missing head reset detector circuit detects the failure of the servo to timely reset the head at the end of the scan of the track or tracks and applies a plurality of properly spaced head reset signals to the movable head assembly to position the head so that the head tracking servo can acquire control over head tracking.

Abstract: ABSTRACT OF THE DISCLOSURE      An instrument for the analysis of a sample material to detect the presence of specific substances that thermal-ly decompose into electronegative species comprises a sen-sitized surface, a heater for heating the sensitized surface in a gaseous environment to generate a gaseous boundary layer adjacent the sensitized surface, a device for causing the sample material to interact with the sensitized surface to form negative ions, a collector electrode maintainable at a different electrical potential from the sensitized surface to cause a current of these negative ions to the collector electrode, and an electrometer for measuring the ion current.  The sensitized surface is formed on a ceramic body that is impregnated with an alkali metal.  The com-position and temperature of the sensitized surface, and the composition of the gaseous boundary layer are selected according to the specific substance to be detected.  Unlike the prior art devices of which the alkali-sensitized sources are themselves abundant positive ion emitters even without the presence of a sample, this instrument has the advantage of a low background level.
