Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for dispensing material, especially tobacco, in portions of predetermined weight from a stream of irregular density.  A variable speed feed system passes the material through a measuring region where its density is monitored and the feed speed is automatically adjusted to compensate for measured variation in the density to provide discharge of portions of predetermined weight from the feed system at regularly spaced time intervals.  The relative separation positions of the portions may be calculated by determining the weight of each portion from both the density information and the feed speed, separation of the portions being effected when the separation position previously calculated reaches the end of the feed system.

Abstract: Abstract In a process for producing a hydrogen containing gas by reacting steam with a feedstock to give a gas at a temperature of at lest 350°C, generating high pressure steam by heat exchange with such a gas, letting down the steam in an expansion engine of the pass-out type and using engine exhaust steam as process feed, an improvement in energy economy is achieved by bringing the engine exhaust steam into heat exchange with water and contacting the result-ing hot water with a gaseous or vaporised feed to the process.  The steam exhausted from the engine is preferably at a pressure lower than that at which the steam-using process step is operated.  The process is especially useful in ammonia production by way of steam hydrocarbon reforming at an unconventionally high pressure in the range 40 - 80 bar abs., followed by synthesis at a pressure not more than 50% higher.         Referring to the drawing, steam generated at 60 bars abs, by inter alia heat exchange with secondary reformer effluent at 30 is superheated and let down in turbine 104 to 19.1 bar abs.  The turbine effluent steam is subjected to direct heat exchange with warm water in tower 120 to give a pressurized hot water stream which then is contacted in tower 128 with natural gas feed the pressure of which is 26.1 bar abs.  The mixture receives an addition of steam at 132, is preheated at 24 and reacted over a catalyst in tubes 22 heated in steam reforming furnace 10.

Abstract: ABSTRACT OF THE DISCLOSURE     The present disclosure sets out an improvement in counterbalanced pumping systems of the type wherein two mandrels are mounted on a common shaft which also is geared through a planetary gearing system to a drive motor.  The mandrels play out, in opposing directions two spirally stack-ed sheave chains, one going to a well bore to support the pumping assembly therein, and the other being extended into a counterbalance pit to support a counterbalancing weight at the end thereof.  The stacked mandrels are enclosed in a common housing which also includes the necessary turning rollers for directing the sheave chains into the respective bores, one end of the housing being attachable directly to the exposed end of the well pipe while the other end of the housing being supported on top of the counterbalance pit liner.  The housing may thus form a leak-proof enclos-ure in which sufficient oil may be stored to lubricate the sheave chains and the mandrels.  There being no further openings in the housing, other than those communicating with the two bores, unwarranted oil spillage is precluded thus observing the necessary environmental standards now in effect.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for restoring image signal levels and setting signal gain for charge coupled  imaging devices (CCDs).  Following the last image signal or pixel in a line of  image data,  a predetermined  sequence of dark  level signals (D) and light level signals (L) are shifted out of the CCD.   The dark level signals are the absence of all image information, while the light level signals represent signals introduced at the appropriate time early in the shifting cycle.   At the CCD output,  the dark and light level signals are  isolated  and processed by an MPU in accordance with pre-established functions to provide an offset potential and gain multiplicand.  The offset poten-tial and gain multiplicand determined are used to remove the offset and set signal gain for the next succeeding line of image signals.  The process is repeated as each line of image signals are output from the CCD.

Abstract: Torch Height Sensing Apparatus Abstract A torch height sensing apparatus is provided for generating information representative of the spacing between a cutting torch and an associated workpiece.  The apparatus drives a preselected current from the torch through the torch flame to the workpiece so that electrons flow from the workpiece through the flame to the torch. The output current biases the flame into the linear region of the preselected voltage-current characteristic at a positive torch to workpiece current.  Biasing the torch for positive current flow from the torch to the workpiece insures that flame height sensing occurs in the positive linear region where the sensitivity is greatest due to the availability of thermally emitted electrons at the workpiece.
