Abstract: ABSTRACT OF THE DISCLOSURE   A current is applied to a thermistor or like heat sensitive element having a temperature-resistance characteristic to heat the heat sensitive element up to a temperature above the open air temperature and the heat sensitive element is held in the open air. Since the resistance value of the heat sensitive element varies with the amount of water vapor contained in the open air, the change in the resistance value is detected, from which the humidity of the open air is obtained. By temperature compensation, direct reading of absolute or relative humidity is made possible.

Abstract: Electronic Compensator for a Pneumatic Servo Controlled Load Bearing Bellows System Abstract An electronic compensation circuit for a pneumatic load bearing bellows system closed on position, in which a servo valve provides pressure to the bellows to actuate the top of the bellows to move to a predetermined position in response to a control signal.  The compensation circuit  (42) cancels at least one load-variable system characteristic which, if not cancelled would cause system instability at system gain levels which are necessary for desired system response.  The compensation circuit electronically provides a replacement system characteristic which permits the system to be operated at a gain level substantially higher than the gain level at which the uncompensated system goes unstable.

Abstract: ABSTRACT OF THE DISCLOSURE     A counterweight system is disclosed, which is advantageously used for counterbalancing the table top of a vertically-adjustable drafting table.  Obviously, the counterweight system could be used for other applications.  When used in a drafting table of the type including a frame and a table top provided with vertical legs guided for up-and-down movement within the frame, cables ore attached to the lower end of the two legs and are trained over a common pulley and attached to said pulley, which is freely rotatably mounted within the frame.  A spiral-shape cam member is fixed to one side of the pulley and an additional cable which is attached to the pulley is trained over the cam member and attached at its other end to one end of tension springs, the other and of which is attached to the frame. The varying force exerted by the springs, with the change of their elongation, is compensated by the variable lever arm of the application of said force on the rotational axis of the cam member and pulley, so that the torque exerted by the springs on the pulley is substantially constant over all of the rotated positions of the cam member and pulley.          Therefore, the load or table top is substantially counterbalanced by the springs at anyone of its adjusted positions.

Abstract: PANEL CONNECTORS          ABSTRACT OF THE DISCLOSURE          Attempts have been made to provide plastic or metal clips to hold panels together either by the adjacent edges with the panels at right angles to one another (cor-ner joint) or with one panel perpendicular to another (T-connection) but such clips are difficult to engage with sufficient frictional force to maintain the panels tightly together.   This invention utilizes firstly an elongated corner strip or moulding having edge beads which snap en-gage grooves in the panel or secondly, an elongated clip or moulding which seats within a groove and extends per-pendicular to the panel with the groove with an edge bead on the distal edge of the portion extending perpendicularly which in turn snap engages a groove in the face of the panel edge which engages the first groove and extends perpendicu-larly therefrom.  In both cases the bead includes at least one elongated key to assist in the frictional retention of the clips or moulding relative to the panels.

Abstract: ABSTRACT OF THE DISCLOSURE             A method and system for controlling natural gas compressor and engine units.  Particularly, the con-trol method provides for the adjustment of the engine speed and compressor loading, so as to minimize the compressing energy required while maintaining a desired gas flow through the pipeline.  The control of the engine speed and compressor loading is based in part on an energy quotient value for the unit.  The control method further provides for efficient operation during multiple-stage compression, by controlling the inter-stage pressure.  The control method is also adapted to predict impending compressor and engine unit failures.          The control system is based upon a digital-type controller which generates control signals in response to changes in the energy quotient value for the unit.

Abstract: ABSTRACT      A device for breaking up a jet is based on the principle that variations in the speed causing the breaking-up are impressed on the jet by inducing pressure variations in the liquid. An agitator disc (16),  provided with perforations  (14)  having a cross-section which increases from one end to the other, is immersed in an enclosure (1) fed with liquid,  and is driven with a reciprocating vertical move-ment e.g. by an electromagnet (13) which acts on a ferromagnetic mem-brane  (11) suspended by an annular spring  (12). The amplitude of the vibrations and the distance of the disc  (16)  from the base  (2)  of the enclosure  (1), which is pierced by calibrated holes  (2a),  are such as to produce a  circulation  of the liquid. within the enclosure re and through the holes, and to produce sized droplets from the ho-les.

Abstract: ABSTRACT Off-gas produced by a blast furnace is treated by scrubbing and cooling the gas with water and then settling solids from the liquid effluent. The liquid effluent is cooled following settling, and a major portion of the cooled effluent is recirculated for another pass through the scrubbing and cooling steps. The remainder of the effluent is chemically treated, and heavy metals are precipitated and settled as sludge. The clarified effluent is filtered and then treated with a cation exchange resin in a sodium cycle. A substantial part of the ion-exchange-treated effluent is returned to the scrubbing and cooling steps, and another substantial part is discharged as blowdown. Return of water which is of adequate quality to prevent scaling significantly reduces the make-up requirements. By discharging the ion-exchange-treated effluent to blowdown while ammonium ions are being removed from standards for maximum blowdown results in an accompanying reduction in the discharge of the other toxic contaminants.

Abstract: ABSTRACT OF THE DISCLOSURE A method for cleaning diffusion tiles used in the oxygen distribution system of the biological treatment ponds of wastewater treatment facilities is disclosed   The build-up of ferric hydroxide scale, which blocks the pores in such diffusion tiles, is removed by (1) purging the oxygen distribution system with a nonoxidizing gas such as nitrogen, (2) injecting substantially pure hydrogen chloride gas through the system which removes the scale, and (3) purging the system again with the nonoxidizing gas before resuming oxygen feed. The use of a nonoxidizing purge gas before and after acid treatment prevents severe corrosion in the oxygen distribution system caused by the simultaneous presence of hydrogen chloride gas and oxygen.

Abstract: ABSTRACT A  slowly  varying  bias  signal is  added  to  one input  of  a  Wave Form Transition  Sequence  Detector,  as  more  fully  described  in  a  related application cited herein, to provide  a differential output therefrom which is directly proportional  to the time between transitions  occurring on two input wave forms.  The slowly varying bias modulates the level of one input wave  form,  and  thereby  varies  the  time  required  for  the  Wave Form Transition Detector to detect a transition occurring thereon.  By symmetri-cally  varying  the  response time  of  the Wave  Form  Transition Sequence Detector to one input wave form in  the neighborhood of the occurrence of a transition on the  second input wave form, the  average differential output of the  Wave Form Transition Sequence  Detector over a cycle  of the slowly varying  bias level  will be proportional  to the  time between transitions occurring on the two input wave forms.

Abstract: CONTROL OF A FLUID CATALYTIC CRACKING UNIT Abstract of the Disclosure A fluid catalytic cracking unit (FCCU) is controlled in such a manner that load is automatically shifted from the wet gas compressor to the air blower for the catalyst regenerator if the loading on the wet gas compressor becomes a limiting factor on the yield of a desired product from the FCCU. Also, the preheat temperature for the feed flowing to the reactor is automatically increased if the desired temperature in the reactor cannot be maintained by increasing catalyst flow to the reactor without exceeding an air blower limitation. This automatic load shifting provides for a substantially maximum production of a desired product without exceeding a process limitation.

Abstract: ABSTRACT OF THE DISCLOSURE           Described is a machine for pre-gluing raw circuit surfaces of printed circuit boards (P.C. boards) at an adhesive station and properly positioning the P.C. boards at a placement station for placament of leadless electronic components (chips) onto the adhesive.  A carousel provides program preselected vertical supply of taped components to a feeder assembly which feeds individual chips onto a nozzle of a turret-type vacuum head at a pick-up station.  The turret-type head has four nozzles spaced 90° apart about the central axis of the head.  As the tur-ret is rotated, a chip is transported  by a nozzle, sequentially, from the pick-up station to a centering and testing station, centering and orienting station, and a placement station.  Lo-cated between the testing and orienting stations is a chip re-moval station for ejecting defective or inverted chips.  Sensors are located at the adhesive and placement stations to detect de-fective P.C. boards so that they may be bypassed.  A controller, such as a digital computer, provides additional monitoring and controls the operation of the machine.

Abstract: ABSTRACT OF THE DISCLOSURE         Method for producing a dull, a grainy, or a sparkling surface on the depressed (mortar) areas of a chemically em-bossed foamed organic plastic sheet.  The sheet is prepared conventionally except that a tacky coating is formed in the mortar areas while maintaining a state of dryness in the land areas; especially by use of a radiation-curable poly-urethane coating which is cured in the land areas by radia-tion while the mortar areas are masked.  Inert particles or flakes distributed over the tacky mortar areas create the desired surface effects when the polyurethane composition in these areas is cured; which is preferably done by the heating employed in the conventional foaming operation.
