Abstract: FEED ROLL ASSEMBLY FOR A FORAGE HARVESTER              Abstract of the Disclosure Harvested crop material is fed to the cylindrical cutter-head of a forage harvester by a feeding assembly consisting of opposed pairs of upper and lower feed rolls.  The two upper rolls are part of an articulated assembly permitting up and down float-ing movement of the rolls as required to accommodate variations in flow of crop material.  The rear or downstream upper feed roll is close to the cutterhead and carried on a pair of opposite radius arms extending rearwardly alongside the cutterhead and pivoted relatively close to the cutterhead axis so that the roll remains close to the cutterhead periphery as it floats.  A transverse leveler shaft rigidly couples the opposite radius arms providing a stable frame for the rear feed roll and minimizing roll cocking or twisting due to forces imposed by a laterally uneven mat of crop material.  A pair of feed roll arms is pivot-ally connected to the radius arms, coaxial with the rear feed roll and extends forward to support a forward or upstream feed roll which is journaled on a shaft rigidly connected between the feed roll arms, the shaft also serving as a structural member having torsion and bending resistance to minimize cocking of the forward feed roll.  Downward movement of both upper rolls is limited by stops bearing, respectively, against an extension of each radius arm forward of the rear feed roll axis and against the feed roll arms close to the forward feed roll axis.  Downward pressure of the rolls on the mat of crop material being fed to the cutterhead is maintained by a pair of tension springs, each connected to an opposite forward feed roll arm about midway between the two upper rolls.  Thus, each upper roll may float independently, the articulation of the feed roll assembly being such that upward movement of either roll or the rolls together is subject to the restoring force of the tension spring.  However, upward movement of the forward roll in relation to the rearward roll is limited by a stop which limits the corresponding rota-tional movement between the feed roll arms and the radius arms supporting the rear and forward rolls respectively.  The down stop for each radius arm is adjustable so that the minimum opening between the rear rolls can be set to suit the crop being harvested.

Abstract: FLUID FILTERING DEVICE Abstract of the Disclosure A fluid filtering device is provided which is parti-cularly suitable for connection with the suction line of a hydraulic system.  The fluid filtering device comprises an elongated housing open at its upper end and secured to a fluid reservoir so that the lower end of the housing is positioned below the fluid level in the reservoir while fluid outlet means are formed on the lower submerged end of the housing.  An annular housing member is coaxially positioned within and secured to the main housing below the fluid level of the reservoir so that the annular housing member is spaced radially inwardly from the main housing thus forming an annular chamber therebetween.  The interior of the housing member is open to the filter outlet while fluid passageways through the housing member establish fluid communication between the annular chamber and the fluid outlet.  Similarly, apertures through the main housing and near the top of the annular chamber provide fluid communication from the reservoir and into the annular chamber thus ensuring that entrained air is swept away and does not enter the filtered fluid flow.  A filter assembly is also provided and comprises a tubular cylindrical filter element having an elongated extension rod coaxially secured at one end to one end of the filter element while an indicator cap is secured to the other end of the extension rod.  The entire filter assembly is insertable through the open upper end of the main housing so that, upon insertion, the filter element is positioned within the annular chamber and thus fluidly between the fluid reservoir and the fluid outlet.  The indicator cap, in turn, is received through an opening in a housing cover plate and provides an exteriorly visible indication that the filter is in place.          A pressure indicator is also mounted to the housing and pro-vides an indication of the degree of clogging of the filter element.

Abstract: PHO 78 . 515 ABSTRACT:               A reproducing apparatus r television signals recorded on a magnetizable record carrier in the form of a tape comprises a rotatable transducer arrangement which for reading television signals which are recorded in adjacent oblique tracks which extend parallel to each other carries two magnetic heads of mutually different azimuth angles, whose azimuth angles correspond to the azimuth angles of the magnetic heads used during record-ing. In such an apparatus steps have been taken to ensure that during a mode of operation with sationary record carrier or with a record carrier speed deviating from the normal speed each of the two magnetic heads reads a track in which the television signals have been recorded with a magnetic head having he same azimuth angle as the mag-netic head reading it. Furthermore, the signal path for the television signals being reproduced includes a delay device for said signals, which shifts the television sig-nals corresponding to the consecutive fields in such a time relationship to each other that, without a phase jump between the horizontal synchronizing pulse trains of con-secutive fields, the differences in the time intervals between every two consecutive vertical synchronizing pulses of each field are zero or a minimum respectively.

Abstract: INVENTOR: JIRI MASTNER          INVENTION: METHOD AND APPARATUS FOR SIGNAL TRANSMISSION     ABSTRACT OF THE DISCLOSURE   By configuring conventional delta modulation with a neutral zone there is obtained improved trans-mission of the modulating input signal.  Additionally, the neutral zone prevents rapid running away of the re-constructed integrated output signal in the event of faulty dropout of signal transmission.  Furthermore, periodic resetting of the receiver side integrator during null thorughpass or crossover of the input signal, possibly artificially produced, enables maintaining a small drift error between the input signal and the out-put signal.

Abstract: TERNARY LOGIC CIRCUITS WITH CMOS INTEGRATED CIRCUITS     Abstract of the Disclosure:           Ternary storage elements are realized using ternary operators and fundamental circuits, designed to make practical use of CMOS (or COS/MOS) integrated circuits.  Word-organized and trit-organized memory cells are designed for the construction of a ternary random-access-memory array (TRAM).  Several flip-flops (tri-flops) are constructed and described in detail, including a PZN (set positive, set zero and set negative), a clocked PZN, a D-type and a T-type.  Ternary shift registers and ring counters are formed by means of these tri-flops.  A master-slave T-type tri-flop is used for the construction of a ternary up counter which is able to count from 0 to 3n using the normal ternary code or from -(3n-1)/2 to +(3n-1)/2 when the signed-ternary code is employed.  With a little modification, a ternary down counter may also be constructed.  A divide-by-M ternary counter which can be programmed is described.  A ternary decoder and encoder are presented, which are the elements of a complete ternary read-only-memory (TROM).  A modified ternary inverter (MTI) is taken as a unit cell of a ternary memory matrix.

Abstract: ABSTRACT    In a polyphase machine, being either a motor or a generator, there is provided a stator core having main stator windings wound about the stator core and main windings having a capacitor connected in series with each winding of the core.  Switches are provided for each winding, and a trigger source for the switches operates with the capacitor and windings to ensure sequential current flow in opposite directions across the windings.  Variable frequency pulses from a trigger results in a variable speed machine.  With control windings wound on the stator, oppositely to the main windings there are currents in each phase which are substantially in-phase at no load with the currents of the corresponding radially adjacent the main windings.          Such currents become out of phase with their main winding currents as the load increases.  At low load the net flux density is low and as the load increases the flux density increases.  With the centers of the poles of the control windings placed as close as physically possible between the poles of the main windings, the magnetic centering of the poles is improved.  The voltage across the capacitor added to the input voltage may causes the stator core to switch periodically between non-saturated and saturated conditions.

Abstract: WINCH SAFETY CONTROL          ABSTRACT OF THE DISCLOSURE      A motor of the type having a low speed ratio and a high speed ratio is disclosed.  A fluid port in said motor corresponds to each of said speed ratios and a port conduit extends from each respective port.  A single valve is operatively connected to all of said port conduits and is spring biased to supply fluid to the low speed ratio.  A solenoid operatively associated with the valve controls the shifting of the valve to supply fluid under pressure to a selective one of said port conduits so that the motor is placed in the speed ratio corresponding to the port receiving the pressurized fluid.  In the preferred embodiment which describes a two-speed fluid actuated motor for a winch on a crane, a first fluid pressure sensor is placed in the low speed port conduit and at a predetermined pressure level in the low speed port conduit sends out an impulse to prevent the solenoid from being energized to shift the valve to supply pressurized fluid to the high speed ratio.  A second sensor is placed in the high speed port conduit and sends out an impulse to disable the electrical circuit of the solenoid to allow the valve to return to a position to supply fluid to the low speed ratio port when the pressure in the high speed port conduit is above a predetermined level.
