Abstract: ABSTRACT OF THE DISCLOSURE    A pair of cutter bar-type mowers are rearwardly and laterally offset on a mower frame having steerable wheels for moving the mower between a cutting position offset from the tractor and a transport position dir-ectly behind the tractor.  A spring-assisted power cylinder raises and lowers the cutting bar from a ground-engaging cutting position to a position with the cutter bar raised off the ground and then to a position with the cutter bar extending vertically for transport.          The spring functions only to assist in raising the cutter bar off the ground by pivoting a frame arm and the pivoting of the cutter bar to the vertical position is by the power cylinder only.  A non-binding power take-off drive is provided between the tractor and the mower with universal joints being provided on the tractor power take-off and on the tongue of the mower at equal distances from the pivotal connection of the drawbar and tongue whereby the tractor turned at a 90° angle to the mower causes only a 45° angle between the drive shaft and the tongue and drawbar.  Each of the mowers are adapted to break away from hitting an obstruction and the drive shaft from the first mower to the second mower includes a rearwardly extending section connected to a gear box in turn having a laterally extending section which is extendable and is connected to a gear box on the second mower pivotal with the second mower when moving between the cutting and breakaway positions.

Abstract: RCA 72,464 Abstract of the Disclosure In a color television receiver including a comb filter for separating luminance and chrominance components of a color television signal, a network is included for selectively restoring and enhancing vertical image detail to preserve and enhance vertical resolution in the luminance content of a displayed image.  The comb filter provides a combed luminance signal output from which vertical detail signal information has been unavoidably deleted, and a combed chrominance signal output including signal frequency components represen-tative of the deleted detail signal, which are selectively extracted from the combed chrominance signal.  Low level detail signals are restored to the combed luminance signal via a first signal processing network with a prescribed restoration gain.  The detail signal is also combined with the combed luminance signal via a second signal processing network which cores (removes) low level detail signals including noise, and enhances higher level detail signals through amplification to enhance vertical image definition. A resultant reconstituted luminance component manifests restored low level vertical detail information as well as enhanced higher level vertical detail information, without enhancing unwanted signal components such as noise.

Abstract: ABSTRACT         A  phase  locked  loop system having improved acquisition time is particularly suitable for use  in  a  television  receiver with  frequency  synthesizer  tuning.  A conventional phase locked loop is modified by the addition of a pair of  transmission  gates and  a  frequency  discriminator/detector.  The transmission gates are normally open, and the phase locked loop  system operates in  a conventional  manner.    When  a  programmable  frequency  divider connected between the output of the voltage controlled  oscillator and  the  input  to the phase locked loop phase comparator has its division ratio changed to select  a  new channel,  the  frequency discriminator,  which  also  is  connected  to  the  output of the programmable frequency  divider,  applies an  appropriate  gating signal to one or the other of the transmission gates to close that gate.  The two gates are  connected  respectively  to  sources  of direct  current  potential  which  operate  rapidly  to  force the maximum control signal on the voltage controlled oscillator in the desired  direction  to  produce acquisition until the phase locked loop is nearly locked.  When the frequency at the  output  of  the programmable  frequency  divider  comes  within a range which is a predetermined amount above or below the desired  center  frequency of  the  frequency  discriminator,  the  output  of the frequency discriminator terminates, opening  the  one  of  the  transmission gates  which  previously  was  closed to return the system back to operation as a conventional phase locked loop system.

Abstract: RCA 71,510 AMPLIFIER WITH CROSS-OVER CURRENT CONTROL                 ABSTRACT     A complementary field-effect transistor (FET) amplifier with means for controlling peak cross-over current.  A substantially constant current is established in the drain-source conduction paths of a pair of reference transistors by degenerative feedback from the conduction paths to the respective gate electrodes thereof; wherein the reference transistors have similar characteristics to the respective amplifier transistors.  The resulting sum of the gate-to-source voltages of the reference transistors is used to apply a bias voltage between the gate electrodes of the transistors in the FET amplifier so that the sum of the gate-to-source voltages of the amplifier transistors is equal to the sum of the respective gate-to-source voltages of the reference transistors during the cross-over current condition.  Cross-over current is thereby limited to a predetermined value proportional to the substantially constant current established through the reference transistors.

Abstract: ABSTRACT OF THE DISCLOSURE     An anti-spill arrangement is disclosed for a liquid electrolyte battery.  The device comprises a chamber configuration or arrangement for containing electrolyte associated with a battery cell, when a battery is tipped toward or onto any one of its sides.  The chamber arrangement has an inlet in communication with an associated battery cell and an outlet in communication with a vent to atmosphere.  The chamber arrangement is such that regardless to which side a battery having the device is tipped, electrolyte flows from the associated battery cell into the chamber arrangement to a level which blocks further electrolyte flow through the inlet.  The chamber arrangement is such that the contained level of electrolyte remains spaced from the outlet of the arrangement.  Thus, this type of device precludes flow of electrolyte out of the anti-spill device when the battery is tipped to any one of its sides.  The arrangement may be such that, when the battery is righted, the electrolyte is returned to the respective cell to thereby restore electrolyte in that cell to its operating level.

Abstract: ABSTRACT      An ejector for firearms which use projectiles without cases of the new design with a perimetric primer. Such an ejector may be used on any type of gun which is equipped with a radial percussion system designed to percuss such projectiles.          Used with the projectiles without cases, the ejector should eject from the detonating chamber of the gun only those project-tiles on which the firing pin has not provoked the detonation of the charge at the moment of percussion. At the same time since it is impossible to prevent from time to time during firing the occurrence of defective projectiles which remain in the barrel, during the phase of introduction into the detonating  chamber the ejector should be able to hook onto every single projectile, retaining hooked onto it only those which, duo to defects, remain in the detonating chamber and leaving all the others free to come out of the mouth of the barrel.
