Title: Improvements in or relating to electric signalling systems
IPC: H04B5/00
Filed: 1927-08-08
Abstract: 300,223. General Electric Co., Ltd., and Cutting, C. E. Aug. 8, 1927. Electromagnets.-The indicator of an electric signalling system is operated by a plurality of electromagnets which are energized in combination or de-energized successively to produce successive indications. As shown in Fig. 2, an arm 21 adapted to operate a rotary drum indicator carries a plurality of armatures 27 which are slidably mounted in holes in the arm and are adapted to co-operate with a corresponding number of electromagnets 30. The arrangement is such that normally the distances of the armatures from the corresponding electromagnets progressively increases from the pivot 23 of the arm. As shown in Fig. 3, the electromagnets are connected in series and the individual electromagnets are connected to the contacts 63 - - 72 of a control switch 80 having two rotatable contact segments 76, 77. Each contact 63 - - 72 may comprise two opposed springs between which the segmemt 77 is adapted to move. The segment 77 is of sufficient width to bridge simultaneously three contacts and thus short-circuit two electromagnets at one time. The segment 76 is moved with the segment 77 and is adapted to maintain a battery connection to the electromagnets throughout the complete operation of the control switch. Upon operation, all the electromagnets are at first excited to operate fully the arm 21 and rotate the indicator drum against the action of the biassing weights 35. Further movement of the control switch successively shortcircuits pairs of electromagnets and thereby allows the release of the arm 21 and the rotation of the drum under the control of the biassing weight. In a modified arrangement the control switch is arranged so that during rotation the electromagnets are energized successively in combination to cause rotation of the indicating drum against the biassing force.

Title: A new or improved method of and apparatus for detection and location of discontinuities in electric cables
IPC: G01R31/08
Filed: 1955-08-04
Abstract: 845,504. Finding faults in cables. MILNER, F. E. Nov. 5, 1956 [Aug. 4, 1955], No. 21087/55. Class 37. Discontinuity in the core of a cable is located by providing an inductive or capacitive pick-up movable relative to the cable and including the coupling provided thereby in the feed-back circuit of an oscillator and detecting the change in the oscillator state (e.g. commencement or cessation of oscillation, or change in amplitude or frequency) as the pick-up moves past the Discontinuity. As shown the two, stage amplifier V  1  V 2  has its output coupled via condenser C9 to one of the conductors T  1  T  3  of a three cored cable by a switching mechanism S  1 . The cable is then run through a channeled coupling member CM connected to the input of the amplifier, the coupling between the member and the core being sufficient to cause the amplifier to oscillate when the discontinuity is reached the coupling is broken and oscillation ceases. The presence of the oscillations is detected by rectifiers W 2 , W  3  which operate. relay K  1  to light a lamp A 2 . If the cable is already laid an extended screened lead for a coupling member may be connected to terminal T  4  and extended leads for lamp may be connected to T  5  and T  6 . Alternatively earphones (connected between T 7  and earth) or measuring instruments may be used to detect variations in the state of oscillation. In a modification the oscillations may be caused to start only when the coupling is broken. In this case the feed-back circuit contains a bridge circuit balanced when normal coupling is effected between the coupling member and the core but unbalanced when a discontinuity is encountered.

Title: Improvements in heating apparatus for motor vehicles and motor boats
IPC: B60H1/00
Filed: 1932-07-26
Abstract: 391,347. Heating-apparatus associated with motor system. LANGBERG, C., 4, Knut Holmsgate, and WATHNE, C., 57, Ladegaardsveien, both in Stavanger, Norway. July 26, 1932, No. 21100. [Class 79 (iii).] A heating device for motor vehicles &c. employs engine exhaust gas for heating fresh air and for driving a small turbine with fan for circulating the air. Exhaust gas is admitted at 5 to the turbine 2, and then passes through the annular space surrounding the casing 3 to the outlet 6. The turbine drives a fan 8 which circulates fresh air through opening 9 and through the heated casing 7 and conduits 10. The front of the casing 1 is made flat to form a hot-plate or cooking plate. To prevent overheating of the fan bearings 12, they are mounted in a tube 13 attached by arms 14 to a coverplate 15. Leakage of hot gas from the turbine casing along the shaft 11 is prevented by a plate 17 pressed against the plate 15 with a pressure which is adjustable by a nut 21. A spring 20 is interposed between the fan 8 and the bearing 12.
Patent GB-661134-A (GB)
Title: Improvements in or relating to high and low water level safety control apparatus for steam generators
IPC: F22D5/10
Filed: 1949-08-13
Abstract: 661,134. Fluid-pressure servomotor control systems; valves. MICHAEL, N. F., WILSON, S., and STEPHEN & SONS, Ltd. A. Aug. 13,1949. 21133/49. Class 135. A combined high and low water level safety control for the steam drum of a steam generator comprises a single float actuating a pair of valves so that it opens one valve when it moves beyond a predetermined position in one direction, and opens the other valve when it moves beyond a predetermined position in the other direction, one of said valves controlling the supply of feed water to the steam drum, and the other controlling the fuel supply to the furnace of the generator. In an embodiment, the float 14, Fig. 2, operates in a chamber provided with water and steam inlets 20, 21, respectively, and the float lever which is pivoted in a block 16 carries counterweights 13 and a cam 15. When the water level rises unduly, the cam 15 acts on and rotates a lever 11, and the other end of the lever, which is connected to a needle valve 18, opens the latter to allow steam from the upper portion of the float chamber to act on a piston-actuated feed water inlet valve B, Fig. 1, to shut off the supply of feed water. When the water level falls unduly, the float causes a second needle valve 18a to open to allow water to flow to a device which closes down a valve F through which fuel-oil is supplied to the furnaces C of the steam generator. The feed-water pump valve 33 and the fuel valve F can be shut down under steam pressure supplied through a line 30 by means of the manually-actuated control valve D. The valve B comprises a lift valve 89, Fig. 4, or an apertured gate valve and it is actuated by a differential or single-landed piston 85. The return movement takes place after the flow of steam through pipe 27 is cut off, and it may be due to a spring 90 or to steam acting on the lower and smaller piston. Steam in the upper part of the cylinder leaks away through a vent 96, this also giving an indication that the valve has operated. The valve may be shut by rotating a handwheel 97 which rotates a sleeve 98 having a screw-threaded connection with the valve spindle. Remote control is provided by a shaft 104 carrying a pinion 103 engaging with a further pinion 102 on the sleeve 98. The valve spindle carries an indicating pointer 101.

Title: Improvements in electric motor control systems, particularly for ship propulsion
IPC: H02P9/04
Filed: 1936-07-30
Abstract: 479,056. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., JEWITT, D. E., and MARSH, R. D. July 30, 1936, No. 21159. [Class 38 (iii)] In a control system for a D.C. motor 1 supplied from a constant voltage source 10 with speed variation by field control, particularly for ship propulsion, a booster generator 2 driven by or independently of -the motor has its armature connected to control the current in the field winding 7 of the motor, the booster having differential exciting windings 8, 9, the former of which is connected in-series with the armature winding of the motor and tends to cause the polarity of the booster to be such as to strengthen the motor field, while the latter is connected to the supply and tends to decrease the strength of the motor field. In the arrangement shown in Fig. 1 (Prov.), the constant voltage source is constituted by four similar generator sets adapted to be connected in parallel to the motor, and the windings 7, 9 are energized through rheostats 5 having four positions I ... IV corresponding to the number of generators in use. The motor is started up through a controller 3, which closes the circuit of the winding 9 at 11 after all the starting resistance has been cut out. The speed of the motor is controlled by a shunt field regulator 4, which is interlocked with the controller 3 to ensure that the latter can only be operated when the regulator 4 is in the " resistance out " position. The two field windings 8, 9 of the booster 2 neutralize each other when the supply current is at its correct value corresponding to the setting of the rheostats 5 ; if the current increases beyond this value, the booster increases the field strength of the motor 1. In the modified arrangement shown in Fig. 1 (Comp.), the field winding 7 of the motor is connected in series with the armature 2 of the booster directly to the supply 10, and speed control is effected by a rheostat 4a in series with the shunt field 9 of the booster. The rheostat 5, with four positions I ... IV corresponding to the number of generators in use, is also connected in the latter circuit. If desired a third winding may be provided on the booster and supplied from the booster terminals.
