Title: Inverted wheel applicator
IPC: B05C1/02
Filed: 1971-12-14
Abstract: 1359549 Coating apparatus LOCKWOOD TECHNICAL Inc 14 Dec 1971 58012/71 Heading B2L [Also in Division D1] An applicator wheel 32 for applying viscous liquid to an upwardly facing work surface is located in a support structure comprising a support block 22 and a face plate 26 having downwardly inclined edges 60, 62, 64, 74 which also slope inwardly and downwardly towards the wheel so that any liquid draining from above runs downwardly and is carried back to the applicator by the edges 34, 36 of the wheel. The excess liquid is carried up into recesses 90, 92 in the members 22, 26 which are spaced apart by a spacer plate 25 which forms a chamber in which the wheel runs. Coating liquid from a supply enters through a passage 49, 44 into a receiving chamber 42 from which it is metered by rotation of the wheel and a doctor blade 50. When the wheel is rotating and no liquid is applied a build-up can be formed in a space 46 in the spacer plate 25. The lower extremes of the edges 64, 74 may be rounded so that droplets form thereon which touch the wheel and are carried away before they reach their limiting size.

Patent GB-724842-A (GB)
Abstract: 724,842. Sparking plugs. GENERAL MOTORS CORPORATION. April 20, 1953 [May 10, 1952], No. 10683/53. Class 7 (4). In a method of treating a low-tension sparking plug in order that it will function at the desired voltage the dis charge path 38 across the in sulation 8 has a voltage appliec thereacross which is higher thar the normal low-tension operating voltage of the plug. Construction. The sintered alumina insulator 8 houses the partially threaded centre wire 10 and the centre electrode 18 which are bonded together by a conducting seal 16 consisting of a mixture of glass and copper or nickel powder ; the outer end of the centre electrode 18 is bifurcated, the prongs 26 being bent over the top of a metal electrode retainer 28. The insulator is secured in the shell 6 by inwardly turning its upper edge over an insulator shoulder 34, a metal washer 48 being interposed therebetween, and urging the inner end 38 of the insulator against an annular shellflange 42 that also serves as the earth electrode. Annular nickel or nickel alloy gaskets 50, 52 are inserted between the centre and earth electrodes, respectively, and the insulator end 38. Conditioning process. After assembly the annular spark gap 44 is conditioned for operation by applying across the plug a short surge of an extremely high voltage or a longer surge of lower voltage. It is preferable to use a series of high-tension capacitive or inductive discharges for this purpose whilst the gap 44 is (a) exposed to the normal atmosphere (b) immersed in a tank of insulating oil for example and (c) again exposed to atmosphere, the voltage at each succeeding step being less than that of the previous one. The discharge voltage may eventually be reduced below the normal operating voltage of the plug.
