Title: Improvements in submarine cable handling machinery
IPC: H02G1/10
Filed: 1922-07-24
Abstract: 207,574. Pernot, F. E. July 24, 1922. Cable ships.-In machinery for handling submarine cables and the like, in which electric machines are used to control the laying of the cable, the energy generated by the machines is used in assisting to drive the ship's propeller or for other useful purposes. The drum 1 drives the dynamo-armature 3, and the field 4 is excited by the source 5 through the variable resistance 6 so that the field and armature combine to exert a torque opposing the rotation of the drum. This torque is measured by a dynamometer in which the fixed coil 12 carries a current proportional to the armature current and the movable coil 11 carries current proportional to the field current. The armature 3 is in circuit with the armature 17 of a motor connected to the ship's propeller shaft 19. The armature 23 of a third dynamo is driven by a prime mover 27 and supplies current to the armature 3 to exert a rotational or braking effort upon it. To provide means for locking the cable-drum, a drum 30 is mounted on the shaft 2 and the pole-pieces 31 are pivoted on the anchor-block 36<1> and magnetized by a coil 34 excited from the source 5. Alternatively the cable drum may be locked by passing current through polar windings on the armature 3. Specification 195,815 is referred to.

Abstract: 354,513. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutler- Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) July 3, 1930, No. 20196. [Class 38 (iii).] Field and armature control; non-regenerative braking.-A motor a is operated either on a lowvoltage supply L1, L2 or a high-voltage supply L1, L3, with its field f weakened after acceleration. If it is then reconnected to the low-voltage supply or braked dynamically, its field is automatically kept weak until the change has been made and then after a short time is increased. A master controller 20 selectively closes reversing switches F or R and low- or high-voltage switches L or H. As acceleration proceeds armature resistance r<1> is cut out by a lock-out switch LO, and a relay V at about full voltage across the armature opens its contacts 17, but the field resistance 11 is kept shorted until the acceleration relay AR opens its contacts 12. The relay V holds its contacts open until the motor has been returned to the lowvoltage supply and thereafter closes with a slight delay to short the resistance 11. De-energization of both switches F, R causes a braking circuit to be established through a resistance r<2>.

Patent GB-204292-A (GB)
Abstract: 204,292. Renault, L. Sept. 22, 1922, [Convention date]. Pneumatic actuation.-In systems employing either a battery or a magneto as a source of current, the change from one to the other is effected automatically by the engine suction. A diaphragm 2, Fig. 4, carries one of a pair cf contacts 5, 8 which form part of the circuit between a battery and induction coil primary winding. A spring 4, also in this circuit, tends to open the contacts against the action of the engine suction which, operating in the pipe 3 and chamber 1, lifts the diaphragm 2 and closes the circuit when, as at starting or low speeds, the suction in the induction pipe is sufficiently high. In shunt with the induction coil is placed the automatic switch shown in Fig. 2, for controlling the distribution of the high-tension current. A bar 10 of conducting material, an insulating disc 13 and an armature 12 are mounted on a pivoted stem 11, the upper bearing 17 of which is connected by a lead 18 to the magneto distributor. Contacts 19, 15 are connected respectively to the insulated ends of the coil and magneto secondary windings. Elecrtromagnets 21, 22 connected across the terminals of the induction coil primary winding act on the armature 12 bringing the bar 10 into engagement with the contact 19 and connecting the induction coil secondary winding to the distributor D. When the suction decreases during normal running the battery circuit is automatically broken and the bar 10 makes connection through the contact 15 between the magneto secondary winding and the distributor. For using the battery continuously an eccentric 24 may be turned to maintain the diaphragm in its raised position. Conversely a turn-cock 26 may be closed if the battery is depleted and the magneto to be used exclusively. In a modification, the automatic switch is provided with contacts for short circuiting the magneto primary when the battery and coil are in use. A single mechanical control may replace the cock 26 and eccentric 24 for keeping the diaphragm stationary in either of its extreme positions. The bar 10 may be maintained in contact with either of the contacts 15, 19.

Patent GB-734288-A (GB)
Title: Improvements in or relating to cold cathode electric discharge devices
IPC: H01J17/06
Filed: 1952-08-14
Abstract: A cold cathode of an electric discharge device is formed at least partly of an alloy of Mg and Li, the Li content being between 10 and 40 per cent of the alloy and being such that all or the greater part of the alloy is in the b -phase having body-centred-cubic structure. The preferred Li content is 10-20 per cent.  In making the alloy, the constituents are heated to 900 DEG  C. in a sealed pot and in an atmosphere of pure argon.  After cooling to room temperature and removing from the pot the solidified ingot is homogenized by heating to about 400 DEG  C. for 8 hours in an evacuated or argon-filled furnace.  The ingot may be rolled into sheet or rod form, and wire may be drawn from the rod with annealing to about 300 DEG  C. in vacuum or argon atmosphere after every 50 per cent reduction in area. In the manufacture of the device, the cathode is sealed into a glass envelope filled with neon at a pressure of 15 mm. Hg and is cleaned by subjecting it to sputtering for about 30 seconds by over-running it with a current of 30 milliamps.  The envelope is then exhausted, filled with 98 per cent neon and 2 per cent argon at 86 mm. Hg and is sealed off, the cathode then being subjected to a further period of sputtering.  The sputtering is stated to deposit some Mg and Li on to the inside of the glass envelope where it acts as a getter for gaseous impurities.  Specification 609,976 is referred to.

Title: Improvements in systems for automatically controlling the speed of electric motor driven hoists and the like
IPC: B66B1/44
Filed: 1934-07-13
Abstract: 440,498. Automatic control of speed ; master control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 13, 1934, No. 20605. Convention date, July 20, 1933. [Class 38 (iv)] [See also Group XXXVII] A hoist motor or the like is so controlled that a mine cage, for example, may be brought to rest with a predetermined rate of deceleration. A generator 34 coupled to the hoist motor 13 produces a voltage, varying with the speed of the motor which is applied to a torque relay 37 controlling the direct or reversed application of power to the motor, but this voltage is modified in accordance with the position of the cage, when within the landing zone, by a resistance 35, in series with the relay, which is varied by fleeting gearing 42, coupled to the winding drum. A snap switch 71 in the relay circuit is operated by the resistance controller, so that the relay circuit is opened from the time the cage is brought to rest until it has left the landing zone. In operation the relay is held against chattering by a magnet 46 when the cage speed is correct, but upon divergence in speed it selectively closes the circuits of relays 60, 75, which energize contactors 16 or 17 to connect the hoist motor to apply driving or plugging torque to the winding drum as required to correct the divergence in speed. Specification 295,650, [Class 38 (iii)], is referred to.

Abstract: 1511045 Rotary disc heat transfer machine D A H HILTON 10 Aug 1976 [15 May 1975] 20753/75 Heading F4K A rotary disc heat transfer machine comprises one or more discs 1 mounted on a hub or drum 2 incorporating a central shaft 3. The discs rotate within a close fitting, partly cylindrical chamber 4 divided into two compartments by radial separators 5. Fluid streams A and B, one heated and the other unheated, flow in opposite directions to each other and counter to the rotation of the discs. The term "fluid" includes gases and fluidized materials. The heat transfer may be from gas to gas, liquid to liquid, gas to liquid or liquid to gas. The fluid streams may be horizontal or vertical and the discs may be in vertical or horizontal planes. The machine may recover heat from exhaust gases from heating, drying or combustion processes. The discs may be impermeable; have plain or grooved surfaces; be of metal, asbestos, plastics or alloys; and be made of, or faced with, hygroscopic materials. In further alternatives, the discs (1A), Fig. 3 (not shown), are perforated or made of permeable material (such as knitted wire mesh or honeycomb structured materials) and have radially extending baffles (9) therebetween which compel the fluids to pass through the discs from sideto-side in a zig-zag course. Separators 5 (or 5A, Fig. 4, not shown) are comb shaped with the discs extending between the comb teeth. Sealing between the separators and discs may be attained by fine clearances, labyrinths or flexible sealing attachments. Fluid may be supplied through passages in the comb teeth to the sides of the discs for sealing purposes or (where the discs are pervious) for purging, cleaning or sterilizing purposes. The shaft 3 may be driven by a geared electric motor at a fixed or variable speed. To prevent cross contamination of one of the fluid streams, this stream may be at a higher pressure than the other.
