Abstract: 192,785. Preston, L. G., and Shearing, G. Nov. 9, 1921. Keying systems and apparatus; thermionic oscillation generators.-In valve transmitting- sets wherein the valves are arranged in series, or in parallel groups with each group comprising two valves in series, signalling is effected by varying the inductance-capacity value G an intermediate circuit coupled to the grid circuits of the series-connected valves. The normal inductancecapacity product of the intermediate circuit is identical with that of the aerial circuits. As shown in Fig. 1, the key S, operated by the Morse key N, short-circuits the inductance K' in a circuit comprising a condenser R and coils L. M which are respectively coupled to coils H, K in the grid circuits of the series valves V<1>, V<2>. These valves are retroactively coupled to the aerial circuit at F. D and G. E respectively. When the key S is closed, aerial oscillations practically cease, whilst the fact that the valves are in series prevents them from burning-out. The coil K<1> may be omitted, the key S then simply closing or open-circuiting the intermediate circuit. Fig. 3 shows a similar keying- arrangement applied to a valve set which is not retroactively coupled. Continuous oscillations are applied to the grid inductances F. G of the valves V<1>, V<2> by coils B', C<1> energized from an independent source. The key S short-circuits a branch inductance K<1> and may simultaneously apply a negative potential from a potentiometer W to the grid of the valve V<2> to prevent overheating.

Filed: 1974-07-05
Abstract: 1459647 Electrolytic capacitors SPRAGUE ELECTRIC CO 5 July 1974 [5 July 1973] 29919/74 Heading H1M [Also in Division C7] A method of manufacturing a solid electrolytic capacitor comprises screen-printing a thixotropic mixture of powdered valve metal and binder on to a substrate of the same valve metal and drying and sintering the deposit. As shown the substrate comprises a layer 41 of e.g. tantalum sputtered on to a ceramic, e.g. aluminium, base 40. Sintered deposit 42 and substrate 41 have a dielectric oxide layer 43 formed by anodizing. A solid electrolyte layer 45 may comprise manganese dioxide formed by pyrolysis of manganous sulphate and the cathodic connection means comprise graphite layer 46, silver layer 47 and solder layer 48. The roughness of the screen-printed surface reduces the number of steps required for solid electrolyte deposition. In a batch process, wherein a number of separate deposits of valve metal powders are screen-printed, a barrier layer 44 of silicone resin or p.t.f.e. may be applied between the deposits after anodizing. After processing, the assembly is cut up into individual or groups of capacitors. Anode or cathode leads are applied to the tantalum substrate and solder coating respectively or, where coplanar leads are desired, a metal bar of the same height as the deposit may be soldered to the substrate (Fig. 8, not shown). Alternatively the capacitor having such a metal bar may be inverted for direct mounting on e.g. a printed circuit board (Fig. 7b, not shown). A non-polar capacitor may comprise two units having a common anode connection constituted by the substrate (Fig. 6a to 6c, not shown), or a multiple unit having a common anode and separated cathodes may be constructed as a dual-in-line package (Fig. 9, not shown). A similar arrangement having separate anodes may be constructed by removing substrate material from between the deposits by means of e.g. a laser beam, and applying a further metal layer to interconnect the cathodes (Fig. 11, not shown). The single or multiple capacitors may be encapsulated.
