Abstract: In a tuning system for a television receiver including a memory for storing binary signals representing tuning voltages corresponding to various channels a viewer may select, during a tuning voltage setup mode in which the binary signals representing the tuning voltages are generated in response to viewer control, a multiplexer couples predetermined selected ones of the binary signals representing the tuning voltages to a digital channel number display unit to provide a viewer with an indication of the relative tuning position.  The multiplexer also couples binary signals representing the letter "A" to the channel number display during the tuning voltage setup mode to distinguish the tuning voltage setup mode from other modes of operation of the tuning system.  In addition, during a channel selection setup mode, in which a viewer selects the channels he does not wish skipped during normal operation of the tuning system, the multiplexer couples binary signals representing the letters "CH" to the channel number display to distinguish the channel selection tuning mode from the tuning voltage setup mode and the normal operating mode.

Abstract: SUSPENSION ARRANGEMENT FOR AN OSCILLATING BODY                 ABSTRACT OF THE DISCLOSURE            A body, which oscillates or vibrates at resonance, is suspended from a support structure so that it has spatially linear motion along an axis for a relatively short distance.  The body has two connected portions spaced from each other along the axis of motion of the body with each portion connected by leaf springs to a separate intermediate frame.  The two intermediate frames are preferably disposed on opposite sides of the axis of motion of the body and connected by additional leaf springs to a main frame, which is suspended by leaf springs from a normally stationary support.  If desired, the two intermediate frames may be driven out of phase with each other with one in phase with the body so that the body has a predetermined path different than spatially linear motion without materially affecting the amplitude of motion of the body along its axis of motion.

Abstract: ABSTRACT OF THE DISCLOSURE           A two stage positive shift starter drive system for an internal combustion engine is disclosed.  A pair of elec-trical switches are sequentially actuated by an actuator solenoid engaging the starter drive's pinion gear with the engine's ring gear.  The first switch actuated after a pre-determined displacement of the solenoid's armature applies electrical power to the cranking motor's through a resistance connected in series with the cranking motor and connected in parallel with the solenoid's pull in coil.  The resistance reduces the electrical power applied to the cranking motor and the potential across the solenoids pull-in coil thereby reducing the rotational speed and the engagement force applied to the pinion gear.  The end of the armature travel closes the second switch applying full power to the cranking motor permitting normal cranking of the engine with the pinion gear fully engaged with the ring gear.

Abstract: ABSTRACT OF THE DISCLOSURE         The method of determining the depth of occurrence of a chemically reactive bed in the course of drilling a well, as proposed in the present invention resides in the fact that the redox potential of the drilling mud situated in the well, is measured, the walls of the well are stripped of the mud cake, and an additional portion of the drilling mud is prepared, whose redox potential differs, as to value and direction, from that of the drilling mud situated in the well,  Then the thus prepared additional drilling mud portion is injected into the well until the drilling mud that has been situated therein previously, is expelled com-pletely, whereupon the circulation of the additional drilling mud portion is suspended for a period of time, wherein relax-ation of the ion-exchange processes between the chemically aggressive bed and the additional drilling mud portion occurs.  After that the circulation of the additional drilling mud portion resumes, while the time interval between the resumption of the drilling mud circulation till the beginning and end of returning the amount of the additional drilling mud portion that has been in contact with the chemically reactive bed, is registered against the deviation of the value and direction of the redox potential of the drilling mud, whereupon said deviation enables the depth of the occurrence of said bed to be estimated mathematically.

IPC: C05C1/00
Filed: 1980-04-17
Granted: 1980-11-11
Abstract: ABSTRACT OF THE DISCLOSURE     To take and use nitrogenous fertilizer on a farm nitrogen dioxide is prepared in a continuous process from air or from ammonia in a reactor, with the ammonia either being transported to the farm or being prepared on the farm in a continuous pro-cess from water and air.  The nitrogen dioxide is mixed with a continuous flow of water to form a dilute solution of nitric acid, which may be applied to the field through the irrigation system as top dressing or mixed within the irrigation system with ammonia or other cations to form ammonium nitrate or other desired nitrogen solutions for application to the fields in a continuous process or concentrated without requiring storage of large amounts of gas or creating heat exchange problems in the manufacturing process.  This process has the advantages of:  (1) continuous in-line utilization of the fertilizer solutions in dilute solution where irrigation is practiced; (2) making the fertilizer solutions in concentra-tions practical for storage and subsequent utilization on farms where irrigation is not practiced or where an irrigation farmer desires to store or use concentrated nitrogen solutions; and (3) controlling the ratio of nitrate to ammonium or other fer-tilizer cations in the fertilizer solution.

Abstract: JPD/lm 23278  3/7/80  A-1 MOISTURE DETECTOR        Abstract of the Disclosure A moisture detector for plywood veneer receives veneer sheets from a dryer on a conveyor and suitably includes adjacently spaced transmitting and receiving plates.  A transmitting plate extends the full width of the conveyor, and is supplied from a transformer winding with a high A.C. voltage which is thereby capacitively coupled to the veneer.  Receiving plates are shielded and segmented, and are connected to separate detector circuits for operating veneer-marking sprayers when a receiving plate receives an A.C. signal of predetermined value indicative of moisture in the wood.  Each detector circuit and receiving plate shield are returned to a first potential reference below conveyor ground level in common with the transformer winding return.  Conveyor ground is connected to a tapped voltage divider disposed across the transformer winding whereby a conductive path is provided to the veneer, for example when the veneer becomes substantially shorted to the conveyor by moisture.  The last mentioned conductive path can alternatively be employed for moisture detection even in the absence of a transmitting plate.
