Abstract: ABSTRACT     A rotary baling apparatus has a wheeled frame that spans a windrow of hay and is moved forwardly therealong, a baling chamber on the frame which receives the windrow as the apparatus is moved along, and means in the chamber for forming the windrow into a spiral bale as the apparatus is moved.  A pair of disks are rotatably mounted in the sides of the baling chamber near the rear of the chamber, and the diameter of the disks is a major fraction of the diameter of a finished bale.          Endless means which is part of the bale forming means has a lower bale rolling run the sides of which are supported on the disks.  The apparatus puts almost no compressive force on the forming bale until after the diameter of the bale is equal to that of the disks, so the bale has a relatively loose core and a firmly packed exterior, and the sides of the bale are relatively smooth and even from being confined between the disks.

Abstract: GAS PANEL SINGLE ENDED DRIVE SYSTEMS                 ABSTRACT OF THE DISCLOSURE    In accordance with the present invention, a simplified panel drive system is disclosed.  The conventional gas panel has two sets of conductors on opposite sides of the panel isolated from the gas by a dielectric coating and positioned substantially orthogonal to each other.  The present inven-tion utilizes one set of drivers to provide a full sustain signal to one axis while the second set of drivers effec-tively provides a ground reference to the second axis.  The axis handling most of the communication is (the "busy" axis) maintained at ground reference, providing continuous com-munication between this axis and the timing and control circuitry, while enough time is available during the normal sustain sequence when the sustain signal is at ground reference to communicate with the drivers utilized with the second axis.  By operating in this mode, the isolation circuitry and driver circuitry together with their associated power associated with the "busy" axis are eliminated, while a uniform intensity display is provided by continuing to operate the panel in the sustain mode.

Abstract: ABSTRACT OF THE DISCLOSURE     This weighing scale has a platform, a load cell supporting the platform and a base supporting the load cell.  The load cell utilizes electrical strain gage elements, which are connected in an electrical circuit controlling an indicator.  The scale is constructed to be unaffected by the eccentricity of the load on the platform.  The scale is particularly suited for use in retail or other establishments, where loads are placed on the platform casually and rapidly, so that eccentric loading is common.          The load cell comprises an integral block of material divided by milled apertures and recesses into two vertical members and three horizontal members connecting the vertical members.  The platform is supported on one of the vertical members.  The base is connected to the other vertical member.          The upper and lower horizontal members carry most of the bending moments due to eccentric loads from one vertical member to the other.  The middle horizontal member is constructed so that it carries most of the vertical component of the load.  The strain gage elements are on this middle horizontal member and thus measure only the vertical load.

Title: Conduction through sensing and inverter protection system
Inventor: YOUNG JOHN A I
IPC: H02M7/525
Filed: 1978-04-13
Granted: 1981-04-14
Abstract: Case 2568 ABSTRACT OF THE DISCLOSURE           A control or protection system for a line commu-tated inverter detects mode 2 conduction-through faults and initiates a control sequence for recovery without shutting down the inverter.  A conduction sensor in each leg provides a signal representing conduction and this is compared with a signal representing the forbidden interval when conduction should not occur in that leg.  When conduction is detected in a forbidden interval it normally indicates a mode 2 conduction-through fault and the gating pulses are advanced for at least the next two pulses to occur immediately but with a limit of 60°.  This causes commutation of the legs which are carrying the conduction-through fault current provided that sufficient volt-seconds remain in the AC part of the circuitry.

Abstract: ABSTRACT                      BRAZING METHOD       Some brazing operations utilize brazing temperatues at which rapid grain growth can occur in the material being brazed. This is particularly true in the case of brazing zirconium ele-ments together with beryllium-zirconium eutectic produced from beryllium coating on the zirconium.  It is proposed to use a two step process in the brazing cycle, initially holding the assembly at a temperature below the .alpha.+.beta./.beta. transus temperature in order to obtain a relatively uniform temperature for all the components and then rapidly cycling components above the eutectic formation temperature and down again before substantial grain growth occurs.

Abstract: UNIVERSAL AUTOMOTIVE ELECTRONIC RADIO     ABSTRACT      Selected radio circuits are fabricated on modules which plug into a "mother" board located in the radio chassis. The circuitry includes a plurality of RF front ends (including at least one AM and one FM front end), each tunable over a selected radio band by tuner circuitry.  The AM front end includes a saturable core reactor whose tuning inductance varies as a function of the tuning current provided to it by a voltage-to-current converter in the tuner.    Both AM and FM signals are translated by a frequency synthesizer to a common IF  frequency, namely 10.7 MHz, The synthesizer employs a quartz crystal controlled oscillator feeding a phase lock loop whose frequency is varied via the tuning control.  Quartz crystal filters for AM, and ceramic filters for FM provide required selectivity.  As all signals are at the same IF, a common IF amplifier is employed, Further, a single phase lock loop is adapted to demodulate both AM and FM signals.    The resultant demodulated signals are amplified, and tone shaped, via D. C. voltage controlled audio processor circuitry.  The audio circuitry is adapted to accept auxil-iary inputs, such as the output of a tape player.    A digital display senses tuner status providing fre-quency read out.  Additional provisions allow switching the display to read out tape player status, or to provide a time display from an electronic clock.
