The endwise movement can be stopped by closing gates at the end of the grooves, in order to prolong exposure to sputtering. The blanks are loaded in a central hopper of a round table vibrated by a torsional vibrator of the type used for tangential feeders. The grooves are offset from the radial direction so that the vibration of the table will impart slight outward impulses to the blanks, which are additionally led forward by a slight downward slant of the grooves. The grooves are semicylindrical and a few per cent larger in diameter than the blanks in order to produce a smooth rolling motion.，下面是Device for exposing small rollable bodies to sputtering专利的具体信息内容。
1. A machine for exposing to treatment the peripheral surface of rollable bodies comprising: a. a grooved vibratory table, having round bottom grooves slightly inclined to the horizontal and of a diameter slightly in excess of the rolling diameter of said bodies b. a distributing head adapted to be loaded with said bodies and to distribute them to the upper ends of said grooves of said table; c. means for vibrating said table with a dynamically asymetric vibration generally transversely of said grooves and having a small component thereof in the direction of descent of said grooves whereby said bodies are caused to rotate in their rolling mode and influenced also to descend said grooves, d. means for treating the peripheral surfaces of said bodies as exposed in said grooves, and e. means for collecting said bodies after they arrive at the lower ends of said grooves.
2. A machine as defined in claim 1 in which the said round bottom grooves are straight.
3. A machine as defined in claim 2 in which each of said grooves terminates at its lower end in a gate and in which there is a shutter adapted to open and to close said gates simultaneously for alternatively arresting the progress of said bodies down said grooves or permitting them to proceed to said collecting means.
4. A machine for exposing to treatment the peripheral surface of rollable bodies comprising: a. a torsional vibrator of the type adapted to propel particles tangentially on a surface carried thereby, b. an output feeder carried by said vibrator having a peripheral channel and an output orifice therefrom, c. a grooved treatment table superposed on said output feeder having a distribution depression for said bodies at its center, a multiplicity of round-bottom grooves slightly wider than said bodies extending outwardly and slightly downwardly from said depression and leading outwardly away therefrom in a direction diverging, at a small angle, from the radial direction towards the direction of propulsion of said vibrator, d. an aperture located over said channel of said feeder at the outer end of each of said grooves, of a size adapted for passage of said bodies one at a time from the groove to said channel of said feeder, e. a distributing head including a loading hopper mounted over said depression, and f. a collecting container disposed below said output orifice of said feeder.
5. A machine as defined in claim 4 in which said grooves are straight and semicylindrical.
6. A machine as defined in claim 5 in which the edges of said grooves are at least in large part below the upper surface of said table and are bordered by lateral bench surfaces lowering the table surface in the immediate neighborhood of said groove edges.
7. A machine as defined in claim 6 in which said bench surfaces are concave and cylindrical.
8. A machine as defined in claim 4 which the lands between the said grooves are faired awAy where the grooves meet said distribution depression, said fairing being solely or perponderantly on that side of a groove from which said bodies tend to arrive to it as the result of being impelled tangentially in the outer part of said distribution depression by said vibrator.
9. A machine as defined in claim 4 in which said loading hopper is cylindrical at least in its lower portion and has a floor higher in the center than at its periphery, which at said periphery is flush with and communicates with said distribution depression through openings adapted for feeding said bodies in a single layer to said distribution depression.
10. A machine as defined in claim 9 in which the floor of said distribution depression is inclined slightly, in a very flat conical manner so that the outer part is a little deeper than the inner.
11. A machine as defined in claim 4 which also includes a shutter mounted at the underside of the outer portion of said table operable to hold either of two positions, one of which blocks all of said apertures and the other of which leaves all of said apertures open, and means for operating said shutter.
12. A machine as defined in claim 11 in which said means for operating said shutter are remotely controllable.
13. A machine as defined in claim 11 in which said means for operating said shutter are a pair of solenoids, each of which is adapted to pull said shutter into one of its positions.
14. An apparatus for treating the peripheral surface of rollable bodies comprising: a. a base; b. a machine as defined in claim 4 mounted on said base; c. an enclosure removably supported on said base and forming therewith a gas tight enclosure surrounding said machine; and d. means for establishing an environment within said enclosure to which said bodies are exposed for treatment.
15. An apparatus as defined in claim 14 for electrostatic sputtering of cylindrical cores in high vacuum further comprising: e. a pressure seal on said base adapted to permit said enclosure to be opened when vacuum is released; f. means for opening and closing said enclosure when no vacuum is present; and g. means for initiating, controlling and arresting the operation of said machine from outside said enclosure, said means for establishing an environment within said enclosure comprising: h. a high voltage sputtering electrode mounted on said base at a distance above said base; i. means for establishing a high vacuum in said enclosure, for maintaining the same and for releasing the same; and j. means for appyling sputtering voltage to said electrode.
