Abstract: ABSTRACT OF THE DISCLOSURE            The moisture content of tobacco, particularly greenleaf tobacco, is reduced to an accurately determined value by conveying a continuous tobacco stream through three successive sections of a transporting system wherein the tobacco is contacted by air currents.          The particles of tobacco are subjected to the homogenizing action of moist air currents in the third and/or first section of the trans-porting system whereby the homogenizing of tobacco in the first sec-tion insures that tobacco entering the second section has a uniform moisture content and the homogenizing in the third section compen-sates for eventual lack of uniform drying action in the second sec-tion.

Abstract: DC EXCITATION OF HIGH PRESSURE GAS LASERS         ABSTRACT OF THE DISCLOSURE A gas laser system with moderate speed gas flow through the optical cavity to facilitate D.C. excitation of the gas to lasing levels.  An electrode assembly is positioned so as to provide a glow discharge transverse to the optical axis within the optical cavity when a high D.C. voltage is applied thereto.  By maintaining the high rate of flow of gas through the cavity, the glow discharge is stabilized while the gas medium is maintained at high pressure.  Proper choice of electrode geometry and flow rate of the gas through the optical cavity allows the laser system to operate at pressures from a few Torr to atmos-pheric pressure and above thereby producing a high power CW output.

Abstract: COLOR NEGATIVE MATERIALS HAVING INCREASED SPEED                 Abstract Color photographic materials are disclosed having red-, green- and blue-sensitive silver halide emulsion layer units, which units contain faster and slower emulsion layers for each color sensitivity.  In such materials it has been found that increased speed can be obtained by manufacturing the material so that, upon imagewise exposure, light strikes the relatively faster green- and red-sensitive layers before passing to the slower green- and red-sensitive layers, but after penetrating the blue-sensitive layer(s).

Abstract: ANTI-ARRHYTHMIC AGENTS     ABSTRACT OF THE DISCLOSURE      This specification discloses a novel series of 5-endo-(3-indolecarbonyloxy)-N-[amino(lower)alkyl]-bicyclo[2.2.1] heptane-2,3-di-endo-carboxylic acid imides processing anti-arrhythmic and/or anti-fibrillatory activity.  The mechanism of cardiac arrhythmia is suspected to be caused by an abnormal "focus" in the ventricle of the heart which sends out (fires) nerve signals more rapidly than required for the normal beat-ing of the heart.  Uncontrolled arrhythmia can lead to fibril-lation which often results in death.  It has been discovered that the above mentioned series of compounds are useful therapeutic or prophylactic agents in the supression of the abnormal ectopic beat.  The present specification, therefore, discloses a compound having the formula I       (I) wherein R7 is H or CH3; R1 is Cl, Br, F, H or (lower)alkyl; R2 and R3 are alike or different and each is H, Cl, Br, F, (lower) alkyl, nitro, CF3, OH or (lower)alkoxy; n is an integer of 2 to 4 inclusive; and R4 and R5 are alike or dif-ferent and each is H, (lower)alkyl or when taken together with the nitrogen a radical of the formula      ,            ,          or           in which R6 is (lower)alkyl; the dextro-or levo-rotatory isomer thereof, or a pharmaceutically acceptable acid addition salt of said compound I or said isomer thereof.

Abstract: ABSTRACT            In this machine, tufts of fibers are delivered from a feed section by an air bridge into a generally vertical chute past a rotary feeder condenser on which the fibers are formed into a mat which is carried onto a feed plate over which the mat is fed by a feed roller into a lickerin rotating at high speed.          The lickerin, which is vertically below the condenser, combs fibers from the mat.  The fibers are doffed from the lickerin through centrifugal force and by an air stream flowing past the lickerin.  The air stream conveys the fibers through a generally vertical duct to an endless belt screen condenser on which they are deposited to form the random fiber web.  The air is recirculated past the lickerin to aid in doffing the fibers from the lickerin.

Abstract: ABSTRACT         A sprinkler flow detector is described which can detect and rapidly respond to the onset of water flow in a sprinkler system which results, for example, from the release of one or more sprinklers,  The detector senses the pressure vs. time profile of the system or house side of the sprinkler system.  An increase in pressure is accurately tracked without causing alarm.  If, however, the pressure falls in excess of certain predetermined rates and amounts, and holds in the lower state for in excess of a second certain predetermined amount of time, the detector enters an alarm state.  In a preferred embodi-ment the detector features a trouble state in which it responds to one of several monitored conditions, for example, a component failure in the detector electrical circuitry, excessive pressure in the sprinkler system, or dangerously low pressure in the sprinkler system.

Abstract: ABSTRACT OF THE INVENTION Flow control apparatus and method for controlling the flow of gravity fed substantially cylindrical objects through a gravity runway wherein a starwheel, a star-shaped ferrous pulse rotor and a ferrous rotor are each spaced from each other and axially fixed to a free wheeling shaft mounted in a frame connected to a gravity runway such that the starwheel lobes jut into and rotate through the gravity runway.  Each starwheel lobe engages each of a successive line of gravity cans as the cans fall through the runway.  A magnetic sensor is mounted on the frame near the star-shaped pulse rotor such that as cans free fall past the starwheels and rotate the free wheeling shaft star points on the pulse rotor rotate past the sensor and disturb the sensor's emitted magnetic field.  For each disturbance, the sensor emits an electrical pulse signal.  Each pulse signal is transmitted to stator coils which extend radially inward on a fixed stator housing concentrically surrounding the rotor such that each pulse signal is capable of magnetically attracting a rotor pole to a stator pole thereby retard rotation of the rotor for the duration of the pulse signal.  The rate of emitted pulse signals indicates the rate of can flow past the starwheels.  Each pulse signal has a voltage of a certain amplitude and external means are provided to pre-set a threshold voltage amplitude which if exceeded by the pulse signal activates and transmits a pulse signal of a controlled duration to the stator pole coils to simultaneously energize all of the coils and stator poles, and for the duration of the controlled pulse thereby momentarily attract the rotor poles thereto and retard individual can flow through the runway. The flow control apparatus can include a magnetic can divider which provides left side, central and right side can output paths.  The electromagnetic rails defining the outer limits of the left and right side output paths become by suitable means electromagnets for diverting output can flow from the discharge end of the gravity runway, from one of the output paths to the other.  Momentary retardation of can flow at the starwheel permits rapid controlled guidance and direction of runway output can flow from one side output path over the central output path to another side output path according to their respective path quantity requirements.
