Abstract: 1,153,787. Discharge apparatus. LIBBEYOWENS-FORD-GLASS CO. 30 Aug., 1966 [1 Sept., 1965], No. 38600/66. Heading H1D. Contaminents are removed from the surface of a substrate 15 by a reactive gas which is ionized and the ions accelerated by a confined electric field to strike the surface and remove impurities by bombardment and by chemical action. The known use of an inert gas is referred to. The substrate 15 is passed through vacuum seals 17, 18 of an enclosure 10 connected to a pump 16. Reactive gas enters the enclosure through apertures 44, 45 in tubular electrodes 47, 48 connected to a negative supply 40 and insulated by non-conductive annular spacers 57, 58 from gas supply pipes 55, 56. A positive static charge builds up on the surface of the substrate if the latter is non-conductive. If conductive, the substrate is earthed. The electrostatic field and ionized gas are confined by a chamber 22 formed by two closed-ended channels 23, 24, e.g. of aluminium. The reactive gas is preferably a reducing agent, e.g. hydrogen or a gaseous halide or a fluorocarbon. A plurality of electrodes may be employed on each side of the substrate 15 and may extend transversely thereto. The enclosure 10 may be modified, e.g. by providing a door, to permit material of other than strip shape to be treated.

Apparatus actuated by a machine to record the number of pieces produced or cycles worked and the reason for any interruptions in production comprises a record disc driven by a synchronous motor and a stylus 38, wherein one electro-magnet 16 causes the stylus to record a stepped, zig-zag trace 39 of which each step represents one, ten or a hundred pieces or cycles and wherein another electro-magnet 40 in conjunction with a selected cam disc 8, 9, 10 or 11 of a time driven contact interrupter causes the stylus to record one of the traces 53, 54, 55 or 56 representative of a reason for interruption. The stylus 38 is carried by a slide 29 reciprocable on guide bars 34, 35 by a heart-shaped cam 26 followed by rollers 27, 28 of which the first 27 is carried by the slide 29 and the other 28 is carried by a lever 30 pivoted on the slide and held by a spring 31 against the cam 26, so that it will not inhibit movement of the slide 29 by the elctromagnet 40. The cam 26 is driven counter clockwise by pawl 20 and ratchet 21 one step each time electromagnet 16 is energized by a machine-controlled switch. The synchronous motor also drives the shaft 7 carrying the discs 8 to 11 each of which has a different number of cams and so closes a corresponding micro-switch 12 to 15 to supply pulses to electromagnet 40 in a different sequence according to which reason-ofinterruption switch is closed by the operator.

The stylus arm is pivotable away from the record disc to facilitate changing of the disc. In an embodiment in which the number of pieces or cycles is represented by strokes on one side of a rest position, the record of reasons for interruption is effected on the other side of the rest position.
