Title: Improvements in or relating to end fittings or joint fittings for electric cables having compressed mineral powder insulation
IPC: H02G15/04
Filed: 1935-08-07
Abstract: 461,239. Cable-end fittings; couplings. CONDUCTEUR ELECTRIQUE BLINDE INCOMBUSTIBLE. Aug. 7, 1935, No. 22324. Convention date, Aug. 8, 1934. [Classes 36 and 38 (i)] An end fitting for a cable having a conductor separated from a surrounding sheath by compressed mineral powder insulation, such as magnesia, comprises an insulating plug fitting within the end of the cable sheath and having a conical portion engaging in the insulation of the cable and a bore through which the conductor passes, and a sleeve which is swaged, welded or otherwise attached to the sheath and holds the plug in position against the end of the cable insulation, the connection of'the sleeve both to the plug and to the sheath being substantially fluid-tight. As shown, the conical part 2 of a plug 1, Fig. 1, e.g. of porcelain, engages a recess in the cable insulation 4, and a metal sleeve 8 connected fluid tightly to the plug is secured by swaging or welding to the cable sheath 6. A metal tube 13 fixed in the plug contacts with the conductor 5 whereby it may serve as a terminal. The tube 13 is closed by welding, or swaging to ensure fluidtightness. Iri the embodiment shown in Fig. 2, the cable conductor passes through the metal tube 13 which is swaged at 13<1> over the conductor and the metal sleeve 8 is corrugated at 12 for resiliency. In modified constructions, the end of the conductor is screw-threaded and a fluid-tight connection between the conductor and the plug is obtained by compressing packing between the end of the plug and a nut which is screwed on the conductor. When the plug and sleeve are separately formed the latter may screw on the end of the cable sheath and be provided with an inwardly directed flange which engage, with the interposition of packing, a shoulder on the plug. Fig. 5 shows the cable conductor 5 joined to another conductor 5<1> by extending the metal tube 13 and swaging, welding or otherwise securing it to both conductors. A joint between two similar cables 5, 6, 5<1>, 61 is formed by fitting double-coned insulating plugs 15, 15<1> to each cable and fitting the cable ends into a metal sleeve 16, Fig. 7, which is welded, brazed &c., to the sheaths 6, 6<1> the conductors 5, 51 frictionally engaging a metal tube 17 insulated from the sleeve 16 at 18.

Title: Improvements relating to electrical sound amplifiers
IPC: H03F1/50
Filed: 1934-08-01
Abstract: 446,891. Valve amplifying circuits. PEDLER, R. D. CARTER-, 187A, West End Lane, Kilburn, London. Aug. 1, 1934, No. 22381. [Class 40 (v)] A high power audio frequency amplifier comprises a plurality of direct-coupled stages, each stage comprising a pair of valves connected in push-pull wherein each stage has an independent source of H.T. supply. In the arrangement shown in Fig. 1 the input from a microphone B is applied in phase opposition to the grids of power valves E, E1 which are balanced by a slider on the grid biassing resistance F connected to the common point of grid resistances D, D<1> and HT-. The anode of each valve is directly connected to the grid of the succeeding stage E2, E3, antioscillation resistances I, I<1> being included if necessary. The anode supply is connected in each valve pair to the centre of resistances G, Gl, G2, G3 &c. Individual anode voltage supply systems are provided for each stage of the amplifier even the valve heater supply being separate from each stage. For high power outputs, e.g. 50 watts, the last valves E4, E5 are directly heated. The grid-cathode circuit is then taken through resistance H3 to the centre of potentiometer H4 across the cathode. In an alternative arrangement the first of the three stages of Fig. 1 is replaced by a single power valve transformer coupled to the push-pull input of two double stages, Fig. 2, (not shown). A complete arrangement of this kind is shown in Fig. 3. The input is derived from a plug S1 supplied from a pick-up source connected across r1 or a microphone from transformer t1, mg being the microphone jack. The first amplifier V1 is transformer-coupled at t2 to the push-pull pair V2, V3 direct-coupled to the directly-heated output stage V4, V5. Valves V1, V2, V3 are supplied from one rectifier system t4, V6, and V4, V5 from the separate system t5, V7. Resistance r4 and condenser c4 are a decoupling combination, while c2, r3 shunted across the primary of t2 causes the amplifier to discriminate slightly in favour of the lower frequencies, thereby correcting for insufficient bass response with gramophone record reproduction. The anode supply to the directly heated pair V4, V5 preferably includes a thermal delay switch, to prevent application of anode voltage until the indirectly heated valves are taking load.
