Title: Submarine cargo trains, with arrangements for the use of obsolete or surplus nuclearsubmarubmarines
IPC: B63G8/42
Filed: 1966-01-17
Abstract: 1,067,703. Submarine cargo-trains. A. P. PEDRICK. Jan. 17, 1966, No. 2049/66. Headings B7A, B7M, B7S and B7V. A submarine cargo-train comprises a plurality of pivotally-connected tubular vessels (20), Figs. 7, 9 and 10 (not shown), containing a multiplicity of cylindrical cargo-containers (21), which are adapted to be mounted on railway trucks for transportation on land, the train being attached at one end to a submarine towing- vessel whose engines are operated by energy derived from a nuclear reactor. A pipe-line (22) extends through the train from the towing vessel and is arranged to admit water to a space between the wall of any of the tubular vessels and the containers therein so as to regulate the buoyancy of the train. The towing vessel may comprise a pair of screw-propellers (7, 8), Figs. 2 and 3 (not shown), which are mounted on sponsors (9, 10) at the stern. The propellers are driven through bevel gearing (2, 5, 6), shafts (3<SP>1</SP>, 4<SP>1</SP>) and clutches (3, 4) whereby one or other of the propellers can be rendered idle to facilitate steering of the vessel. Alternatively, the towing vessel comprises reaction-propulsion units (11, 12), Figs. 4 to 6 (not shown), attached to sponsors (13 ... 16) on the side of the hull. A bell-shaped body (23), Fig. 12 (not shown), may be fixed to the towing vessel to reduce the drag caused by the vessels (20). A float (18) carrying a radio aerial (19) may be attached to the towing vessel to permit remote control thereof, e.g. by earth satellites.

Abstract: 1533502 Standby supply systems ANTON PILLER KG 19 Jan 1977 [20 Nov 1976] 02068/77 Heading H2H A battery/mains generator set for providing a continuous supply of power to a load 24 comprises an A.C. machine 6 capable of operating either as a generator or as a motor and mechanically coupled to a D.C. machine 4 also operable either as a generator or as a motor. When the mains supply 32 is present, the load 24 is supplied via a switch 34 such as reverseparallel connected thyristors and the machine 6, driven as a motor, drives the machine 4 as a D.C. generator to charge the battery 18. If the mains supply fails, the battery 18 drives the machine 4 as a motor which drives the machine 6 as a generator to supply the load. A speed regulator 46 controls the supply of an exciter winding 10 in dependence on the current detected by a transformer 44 and the voltage of a D.C. generator 8. An exciter winding 12 of the generator 6 is controlled, in dependence on the reactive current consumed by the load, by a regulator 38 connected to a current transformer 36 and the output of the generator.

Selectors responsive to code signals. - An electric selector adapted to respond to a signal comprising, for example, two one-second impulses with a one-second interval. followed in turn by a three-second interval and three one-second impulses with one-second intervals, comprises a code wheel 10 having indentations a and projections b corresponding to impulses and intervals respectively, which is held in engagement with a clockwork drive 1 - - 4 throughout a correct signal. The wheel 10 is held in engagement during the intervals by electric or mechanical means operated by the .projections b. The projections take slightly above the correct intervals to pass a given point and the indentations less than the impulses. The selector may be operated over wires or by radio signals and may be used for setting clocks, lighting lamps, or starting recording apparatus The wheel 10 is journaled in one end of a. lever 14, 15, pivoted at 16, the other end of which lies between adjustable stops 19. A signal received over wires 36 energizes relay 33 to operate magnet 20 which swings lever 14, 15 against a spring 18 so that a gear wheel 7 fixed to wheel 10 engages the drive. In this movement, a wiper 22 originally engaging a stop 24 is forced by a spring 25 into contact with the code-wheel periphery. The code-wheel is rotated against a spring 12 which with the wheel 10 is insulated on the spindle 8. During the intervals a circuit 30, 32, 27, 12, 10, 22, 25, 26, 20, 31 is closed to keep magnet 20 energized. When the complete signal is received an arm 11 on the wheel 10 engages a stop 13 to complete a circuit over wires 35 to operate the required apparatus. In a modification, Fig. 4, the code-wheel is annular, and is held in engagement during the intervals by a fixed pin 43 which engages within the projections 42.
