Abstract: 339,049. Electrical Research Froducts, Inc., (Assignees of Legg, V. E.). Nov. 8, 1928, [Convention date]. Loading circuits to improve transmission.-In a long submarine signalling cable, the end sections are loaded with a greater thickness of magnetic material than the centre section, and the material of the end section loading has a lower hysteresis loss, lower resistivity, and a higher constancy of permeability for a wide range of magnetizing forces than that of the centre section. In the embodiment, the central portion B of the conductor 12, which is covered with strands 13, is loaded with helical tape 14 which is a composi. tion containing, Nickel 45 per cent, Iron 23 per cent, Cobalt 25 per cent, Molybdenum 7 per cent, Silicon 47 per cent and stated to have an initial permeability of 875, a resistivity of 82 microhmcms, and a variation of permeability greater than that of the end section loading. Another material referred to for loading the central section consists of Nickel 55 per cent, Iron 34 per cent and Chromium 11 per cent. The increased thickness of loading material on the end sections may be obtained by applying a thicker tape or, preferably, by applying more layers of tape. In the embodiment, the end sections A, C are loaded with two layers of tape 14, 16. A material referred to for loading the end sections comprises Iron 27 per cent, Nickel 45 per cent, Cobalt 25 per cent, Molybdenum 2.5 per cent, and Manganese 0.35 per cent, and, after heat treatment is stated to have an initial permeability of 480 which is constant up to magnetizing forces of about two gauss.

Title: Improvements relating to the starting of engines
IPC: F02N99/00
Filed: 1945-11-16
Abstract: 603,760. Starting prime movers. RUTHERFORD, R. E., and LAGONDA, Ltd. Nov. 16, 1945, No. 30763. [Class 38 (iv)] [Also in Groups XXVII and XXXVII] A device for inserting in the starter circuit of an internal-combustion engine to prevent the said starter from being used when the engine is running consists of a contact W, which bridges the contacts U and V in series with the energizing circuit of the starter solenoid D, and is connected to a magnetic core R slidable on the rod L and held against the nut a by a light spring S. The other end of the spring bears against a diaphragm J which is held in the starting position shown by a spring K bearing on the casing G which also contains a solenoid coil N in series with the terminals Y and Z through the contact W, the left-hand side of diaphragm J being connected to an engine hydraulic pressure supply. When the starter switch F is closed the solenoid N is energized and connects member W across the points U and V and the engine is turned by an electric starter with armature A and field coil B. Hydraulic pressure immediately builds up and forces the diaphragm J and hence the rod L towards the cover X but the solenoid N retains the core R and contacts W until the engine starts and the switch F is broken. The contact member W then breaks the circuit between U and V and renders it impossible to use the starter gear until the engine has stopped, in which case the mechanism will return to the starting position shown owing to the failure of the hydraulic pressure. Specifications 529,760 and 555,630, [both in Group XXIX], are referred to as describing a type of hydraulic governor to which the device could be connected.
