Abstract: ABSTRACT OF THE DISCLOSURE A digital chrominance signal in a digital component television system is digitally filtered to obtain sampling values intermediate the sampled values obtained during analog to digital conversion of the chrominance signal, such that the . resultant number of chrominance samples per second in the digi-tized chrominance signal corresponds with the number of luminance samples per second in the digitized luminance signal.  The sampled values of the digitized chrominance signal including the computed intermediate values may also be modified by said digitized filter to minimize the alias created by the analog to digital correction sampling process,  to compensate this signal. for sine x/x losses existing in the digitized chrominance signal, to compensate for Gaussian filter attenuation of the chrominance signal prior to analog to digital conversion thereof, and to compensate for other deficiencies in the chrominance signal. the digital filter includes a network of at least one shift register and one digital adder that continuously calculates intermediate values between successive sample  values of a digital chrominance signal, and incorporates said calculated values in a resultant chrominance signal.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention disclosed is an FET oscillator, including means for controlling the gain of the oscillator to control its output level to thereby avoid limiting, and thus to reduce distortion of the oscillator output.  A feedback loop is serially connected between the drain and gate electrodes to cause the gate direct voltage to increase negatively as drain output amplitude increases and thus reduce drain current and stabilize oscillator gain.  The level of oscillation is adjustable by a potentiometer connection to the sate.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for automatically making harnesses such as those used for electrically interconnecting a plurality of spaced-apart, separate connection points.  Insulated wire is fed through a press position where terminals are attached to the wire con-ductor.  The insulation is displaced from a portion of the wire where a terminal is to be attached, thereby baring the conductor.  A terminal is brought adjacent the bared conductor from a supply of terminals and crimped to the conductor.  A wire feeding mechanism advances the wire so that the section having a terminal crimped thereto is removed from the press position and a new portion is brought into the press position for the attachment of another terminal.  The automatic process is repeated until a pre-determined number of terminals are attached to the conductor at which time the wire can be severed to complete the manufacture of the harness.  The apparatus has a control means which is programmable so that one of a variety of harness configurations can be set up and manu-factured repetitively.  The control means also enables the apparatus to operate in different modes such as one-step, one-cycle or continuous-cycle.

Abstract: Abstract of Disclosure Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel, despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece or a succession of workpieces proceeds. Generally, as a common denominator of the novel features disclosed, a "conditioning element" is brought into rubbing contact with the face of the grinding element under specially controlled and unique conditions to (i) restore the desired shape (conventionally called truing), or (ii) to establish the desired degree of sharpness (conventionally called "dressing"), or to accomplish both (i) and (ii) simultaneously.          The methods and apparatus disclosed include creating the aforesaid controlled rubbing contact either while the grinding wheel is free of grinding contact with a workpiece or simultaneously while grinding is occurring, and then either continuously or intermittently. The methods and apparatus in many of their various embodiments involve use of a "truing element" or a "conditioning element" which may be a generally homogeneous metal, and in many cases the same metal as that of the workpieces being ground. This advantageously results in lower costs as well as greater productivity and workpiece quality (both size tolerance and surface finish). In their different facets, the disclosed inventive features involve truing of wheel faces in a fast, economical fashion by controlling relative surface speeds and feeds of the wheel and the conditioning element; conditioning wheel faces to be sharp or dull to provide efficient rough grinding or precise finish grinding with a desired surface finish; and workpiece size control (despite wheel wear reduction in wheel radius) by either no gage at all or a simple gage sensing the conditioning element rather than the workpiece.

Abstract: Abstract Of The Disclosure An annular seat for use in a ball valve has two groups of pressure relief passageways each of which extends completely through the seat between its front and rear faces.  The relief passageways in one group are located adjacent the outer periphery of the seat.  The passageways in the second group are located radially inward of the passageways in the first group, and extend between the rear face of the seat and a curved sealing surface on the front face of the seat.  A pair of such seats are disposed in a ball valve housing adjacent opposite sides of a rotatable ball.  The interior seat support surfaces in the housing have machined recesses adjacent the central axial fluid passageway through each seat, to facilitate lip flexure of the seats.  The overall arrangement provides a bidirectional valve which seals on the downstream side only of the valve, and which relieves excessive cavity pressure in the valve past the upstream seat.  The seats may be provided with chamfered outer rear corners to facilitate the pressure relief operation at the upstream side of the valve under conditions of extremely rapid cavity pressure generation.

Abstract: QUICK DISCONNECT NOZZLE           ABSTRACT OF DISCLOSURE               The invention comprises a quick disconnect nozzle including a nozzle body and a nozzle tip, wherein the nozzle body may be connected to a source of fluid and the nozzle tip is separable from the body by a single twist type action, yet the nozzle may be securely locked in the body by an interlocking engage-ment between the nozzle and body that is engaged and disengaged by relative twisting of the two parts.          The locking action is obtained by the engagement of cooperative elements on the two  parts including oppositely disposed undercut shoulders on the nozzle body and a pair of rounded projections on the nozzle tip which are engaged under the opposing shoulders by the relative twisting action.  The interlocked relationship is maintained by a combination sealing member and pressure device that effectively seals the connection between the nozzle body and tip and exerts pressure therebetween to  secure the locked connection.

Abstract: ABSTRACT         Diaproticiticidal effectiveness and diabroticite specificity of insecticides is enhanced by admixture with dry cucurbitacinous products derived, preferably, from hybrid Cucurbitales plant tissue.  Hybrid plants bred from (wild) bitter Cucurbitaceae species and (domesticated) non-bitter species (e.g., Cucurbita andreana x C. maxima or C. texana x C. pepo) provide high yields of plant fruits with high concen-trations of cucurbitacins, which are attractant/arrestants and feeding stimulants for diabroticites.  In one embodiment, dried ground fruits of Cucurbita hybrid plants are admixed with essentially minute quantities of insecticides to provide diabroticite-specific insecticide compositions allowing for effective, economical, environmentally safe control of diabroticites such as corn rootworm beetles.

Abstract: ABSTRACT "CONTROLLED-PHASE R.F. SYSTEM"   A system for amplifying R.F. signals with a selectable substantially constant phase at the output port (OP) relative to the input port (IP) comprises a phase shifter (PS) and an amplifier (AMP), a phase discriminator (PD) and a video processor (VP) which controls the phase shifter (PS) in accordance with the output of the phase discriminator (PD) and a phase selection signal (SEL).  This signal (SEL) selects a bias voltage to cause the phase shifter to introduce a phase shift such that the relative phase at the output port is approximately equal to a desired value and also to select a monotonically varying error function which is derived from the phase discriminator and which is representative of the difference between the desired value and the actual value of the relative phase.
