Abstract: 613,670. Condensers. DUBILIER CONDENSER CO. (1925), Ltd., and BENNETT, A. E. C. June 25, 1946, No. 18991. [Class 37] A condenser of the kind comprising an insulating support or carrier, e.g. a pot, tube or cylinder carrying the electrodes, has at opposite ends mounting terminals formed as thin metal hollow bosses or tubes screw-threaded internally and externally to co-operate to form a series condenser stack. A ceramic pot A with outer and inner silver electrode coatings B, C has screw-threaded tapered thin metal tubes B3, C3 soldered at B1, C1 to the electrodes for attachment to a similar terminal on another condenser for connection in series or to metal bridges D, E with terminals X, Y, so that condensers or stacks of condensers are connected in parallel. The tubes are pressed to form the screw-threads, and the tube C3 is closed at one end to seal the pot A. Caps E2 are screwed over the condensers so as to contact the upper bridge E, which is formed as a corona shield. The pot A has an integral bell A1 formed with a smooth curve along which the electrode extends at B2 to lessen dielectric stress. In Fig. 3, the condenser comprises a ceramic cylinder with an integral transverse septum F1, electrode coatings H1 being applied to the inner cup-like recesses so formed, the thin metal terminal tubes being soldered at G4 to the coatings and passing into or over the open ends of the cups, which they may seal. The septum merges in smooth curves into the cylinder. Corona shields attached to or integral with the terminals extend out beyond the cylinder. When a condenser group is to be insulated from earth, it may be mounted on insulating pots or cylinders coated with metal only where the terminals are soldered thereto. An additional bridging bar may be mounted intermediately the terminal bars.

Abstract: 517,772. Aerials. CORK, E. C., and PAWSEY, J. L. June 28, 1938, No. 19094. [Class 40 (v)] Relates to aerial systems, particularly for short-wave working, in which tubular radiating elements are arranged coaxially with, say, the iron mast of a ship. The object of the invention is to minimize the effect of the iron mast in dissipating power, or in distorting the radiation field. In one embodiment, Fig. 1, a metal mast 1 is surrounded by a tubular half-wave radiator 2 fed at its lower end by the coaxial line 3 the sheath of which is earthed at the points e, adjacent the radiator and d at a quarter wavelength therefrom. The mast 1 is earthed at the points b, a adjacent the ends of the radiator and the point c a quarter wave-length from a. The centre point of the radiator 2 is directly connected to the mast 1 by the member f so as to ensure a high impedance between the radiator and the mast; but this may be omitted, Fig. 2 (not shown). In a further embodiment, Fig. 3 (not shown), the upper end of the radiator is connected to a feeder branched off from the main feeder 3 at a point a quarter wavelength from the lower end of the radiator. In another form, Fig. 4, two half-wave tubular radiators 2a, 2b spaced half a wave-length apart are fed in anti-phase at adjacent ends from the single feeder 3 and are connected to the mast 1 at their mid points. Specifications 5387/00, [Class 40], 489,775 and 509,500 are referred to.
