  • Patent number: 4558256
    Abstract: The "comb-quad" slow-wave interaction circuit for a traveling-wave tube consists of a pair of metallic ladders whose rungs cross, the rungs of one ladder passing through the spaces between the rung of the other ladder.The phase velocity of the circuit wave is tapered to a lower value at the output end by gradually enlarging the axial open spaces between the longitudinal bases of the ladders and the surrounding envelope. The periodic elements of the ladders are all exactly alike, simplifying the construction.The slowing of the wave velocity is greater at the lower-frequency end of the passband, providing improved efficiency over the operating band.

  • Patent number: 4539064
    Abstract: In a method of splicing strips of thermoplastic material to form waterstop joints, the strips are first clamped in longitudinal alignment with their adjacent ends spaced apart. While the strips are so clamped, a routing tool is used to cut complementary rebates at these adjacent ends, after which the strips are moved into end abutting relationship while the longitudinal alignment of the strips is maintained, the rebated ends being brought into a half-lap configuration. The cooperating ends are then welded together by means of an electric heating element which was inserted between the ends prior to their being clamped together.

  • Patent number: 4529464
    Abstract: Disclosed is a container especially adapted for use in storing and heating comestibles intended for final preparation in microwave ovens. The container comprises a molded pulp tray, having a plastic film, preferably a polyester, adhered to its product-contacting surfaces. The container exhibits high strength and excellent product protection, but yet is low in cost. The process for making the container takes advantage of the porous nature of the pulp tray by drawing a vacuum directly through the tray to draw a film of heated plastic into adhering contact. The film is preferably extruded as the tray, carried in a vacuum mold, passes directly under the extruder.

  • Patent number: 4498944
    Abstract: An apparatus and method is disclosed for attaching a continuously moving elastic ribbon to a continuously moving web such that only selected discrete areas of a finished conformable garment fabricated from the web are elasticized. The web is moved into engagement with a continuously moving first conveyor means having a plurality of spaced apart gaps in its surface and the first conveyor means travels along an inclined guide means toward a second conveyor means traveling opposite to and in the same direction as the first conveyor means. The second conveyor means carries a plurality of spaced apart web tucking means which are moved by the second conveyor means into registry with the gaps in the first conveyor means. As each of the web tuck means move in registry with the gaps, the web tuck means are inserted into the gaps to form tucks in the web due to the movement of the first conveyor means toward the second conveyor means.

  • Patent number: 4482424
    Abstract: A method for lithographically fabricating devices is disclosed. In accordance with the method, a sacrificial coating material (SCM), e.g., a resist, mixed with a fluorescent material is deposited onto a substrate and then etched. SCM etching is monitored by subjecting the fluorescent material within the SCM to fluorescence-inducing energy, and detecting the resulting fluorescence. Because the fluorescent material is etched away as the SCM is etched, fluorescence intensity decreases as SCM thickness is reduced. Thus, SCM etch end point is accurately determined because etch end point corresponds to the point in time when the detected fluorescence ceases.
