Abstract: SLIP JOINT AND METHOD OF MAKING SAME             Abstract of the Disclosure:   A slip joint including telescoped inner and outer members having substantially unstressed plastic material interposed therebetween.  The joint is made by first telescoping inner and outer members with the plastic material interposed therebetween.  The outer member is then  deformed inwardly to place the plastic material under considerable com-pressive stress.  The deformed area is then heated for expanding the plastic material and relieving the compressive stress by plastic movement of the plastic material.  The plastic material is then cooled and minimal sliding clearance is provided between the inner member and the plastic material.  The outer member is thus deformed inwardly in at least one localized area and the plastic material has a thickness beneath the deformed area which is substantially less than the thickness thereof beyond the deformed area.

Abstract: COMB FILTER APPARATUS FOR VIDEO PLAYBACK SYSTEMS Abstract of the Disclosure Comb filter apparatus for separating interleaved luminance and chrominance components of a composite color video signal employs a clock controlled delay line of the CCD type to which the composite signal is applied.  A VCO supplies clock signals to the CCD delay line, and to a frequency divider.  The output of the frequency divider is compared in phase with a color synchronizing component of the undelayed composite color video signal to develop an error signal, which is applied to the VCO in a sense opposing departures from a predetermined phase relationship between the divider output and the synchronizing component.  Spurious frequency variations of composite signal components (e.g., accompany-ing recovery of composite signal by playback of a video disc) are followed by the VCO in a manner assuring that accurate combing of the composite signals occurs at the outputs of circuits providing desired combinations of the delay line input and output.

Abstract: ABSTRACT         A brake or clutch pedal actuated safety switch for use with an automotive speed control system is disclosed.  The switch opens an electric circuit and admits atmospheric air to a vacuum line when the brake pedal or clutch pedal is depressed.  The elec-tric circuit normally opens first to deactivate the speed control system electrically at the system's regulator, and the vacuum line is opened subsequently to act as a backup for deactivation of the system.  A rotatably mounted lever member, biased by a spring toward the deactivating position, controls both the electric and the vacuum circuits.  When the pedal is fully released and returned to its undepressed position, a tension line rotates the lever member against the bias of the spring to a position wherein the electric circuit and the vacuum line are closed.

Abstract: ABSTRACT OF THE DISCLOSURE         A lamp assembly for a runway is disclosed.  In a housing is disposed a single prism which has an apex projecting above the cover of the housing.  A light source located below the prism produces light which is focussed by a parabolic reflector through the bottom of the prism.  The light is internally reflected within the prism before emerging from the projecting portion near the apex.  The bottom surface of the prism may be ground to provide focussing within the prism.  In use the assembly is mounted in a runway with a cover plate flush with the ground.  The basic form of the prism can thus be modified easily to satisfy different optical requirements.

Abstract: ABSTRACT OF THE DISCLOSURE            Markedly superior corrosion protective properties are imparted to metal-bearing surfaces at substantially reduced costs by depositing upon said surfaces one or more superimposed zinc containing layers located intermediate the metal bearing surfaces and a sacrificial layer of generally pure zinc.  The initial layer which is in direct contact with the metal bearing surface includes therein from about 3 to about 15% of an alloy-ing element selected from the group consisting of nickel, iron or cobalt and a second layer deposited upon the initial layer having a relatively lower content of the alloying element as compared with the initial layer.  In this manner penetration of rust inducing substances into the metal bearing surfaces is effectively precluded under substantially all environmental conditions normally encountered.

The cured paint has excellent gloss stability due to the chemical incorporation of the stabilizer segments throughout the binder resin molecules.
