Apparatus for carrying loads into and from a hold or other covered space comprises a wheeled carriage running on overhead rails in the space, a hoisting rope for suspending directly or indirectly the load such that the load and carriage together move outside the covered space and the carriage is adapted for being engaged with and disengaged from the rails when the load is lowered into or removed from the covered space. As shown in Fig. 1, a hoisting rope 5 attached to a carriage 6, which has rollers 7 for running on tracks 4 secured beneath a deck 3, carries a pulley block 8 secured to trunnions 13, and a hook 9 for the load. The rails 4 have a downwardly-curved extension for guiding the carriages on to the rails and an arm 12 attached to the coaming has a roller I for guiding the rope 5. The carriage and load are lowered to contact the rails and the carriage then rotates about the trunnions 13 for transporting the load in the covered space. In a modified form, Figs. 4 and 5, the carriage comprises pairs of rollers 30, 31 and a rocking axle 33 to which are secured spaced plates 35 carrying a pulley block 36. As the carriage is lowered so that the rollers engage the rails 24, holes 56 in. the carriage are brought into engagement with holes 57 in the plates and are secured by a spring-pressed bolt controlled by means 55. Cables 38 and 39 pass from the pulley block round pulleys adjustably positioned in the plates and have hooks for securing to the load. The rails have pivoted or slidable rail extensions hooked on to members 109. As shown in Fig. 5, the rail extensions 22 are attached to lateral plates 21 slidable or rolling on the coaming to extend beyond the rails 24. The rope 53 attached to the carriage is correctly positioned by a rope 48 and pulley 47 controlled by a winch 49, which may be movable along the coaming or secured to members 50. The shell 59 of the pulley 47 may have a rope brake to allow detachment from the hook 46 of the derrick rope when the carriage contacts the rails. A number of carriages may be connected together for simultaneously transporting a number of loads by suspending them from hooks on a beam and the guide-plates may be simultaneously moved by operating a lever. The lever moves two rods in opposite directions, the alternate guide-plates being connected to each rod so that the plates are moved into operative or inoperative position.

Title: Improvements in or relating to electric switches
IPC: H01H50/64
Filed: 1923-07-10
Abstract: 222,949. Norballe, H. J. July 10, 1923. Electromagnetic switches; latching and unlatching; contacts; sparking, preventing.- In a switch of the type wherein the movable contact-piece is carried by an auxiliary lever that is pivoted on the switch-arm and pressed forward in the closing direction by a spring, the auxiliary lever has two arms extending on either side of its pivotal axis, and carries a contactpiece on each of the arms co-operating respectively with two stationary contacts. One of the latter is so situated as to engage the contact on the arm that is pressed forward before the other or main stationary contact engages its co-operating contact on the second arm, whereby the movable main contact is given a translational and rotational movement in closing. As applied to an electromagnetically-operated switch, the switch-arm 10, operated by an electromagnet 11, is pivoted at 14 and has pivoted to it at 15 an auxiliary lever of which the arms are 16 - - 18 and which is rocked in an anticlockwise direction by a spring 19. The contacts comprise the arm 16 and a contact 20 on the arm 17, current being conveyed thereto by copper braid 21, and cooperating therewith are leaf contacts 23 and a contact 24 provided with a series blow-out coil 25 and arc-shields 28. A latch 31, pivoted at 32, has a shoulder 30 engaging a pin 29 on the arm 10 to prevent its being manually closed; it is coupled by a light rod 33 to a light pivoted armature 34 so that when the magnet is energized, the light armature will be raised to lift the latch 31 first and then permit the relatively heavy arm 10 to move. In operation, the circuit is first closed at contacts 20, 24 and at the end of the movement, the arm 16 is rocked about the pivot 15 and gives a gentle raising movement of contact 23 and a sliding movement of the same on arm 16. A sparking tip 36 may be provided owing to the voltage drop across the blow-out coil when the switch is opened. When applied to contactors, the contact 23 is replaced by a strip 37 and block 38, as shown in Fig. 3. With this arrangement, rebound of the contacts is almost eliminated, or should it occur at all sparking is limited to a part of the contacts not normally in use. According to the Provisional Specification, the main and auxiliary contacts are closed almost simultaneously and, being arranged in parallel, rebound of one of them will cause the others to be pressed together harder.

Title: Improvements in and relating to wireless signalling systems
IPC: H01Q11/02
Filed: 1922-06-28
Abstract: 203,446. British Thomson-Houston Co., Ltd., (General Electric Co.). June 28, 1922. Addition to 192,346. Aerials; directive signalling; mu!tiplex signalling; undesired signals, eliminating or limiting. -Comprises various modifications of the receiving apparatus described in the parent Specification, in which a long horizontal two-wire aerial functions both as a receiver of the wave energy and as a transmission line for conveying that energy to the receiving set. As shcwn in Fig. 2, the aerial 1, 2 is grounded at both ends 3, 4. At the end 3 nearer to the transmitting station, the earth connection includes a variable resistance 14, capacity 16, and inductance 15 all in series and arranged to control the reflection of currents in the aerial. At the end 4 at which the desired signals are strongest, the earth connection includes a primary coil 7 inductively related to a divided secondary coil 8, by which currents are transmitted round the circuit 1, 2. At any desired point of this circuit, transformers 17, 18 transfer the signal energy to the receiving set. Capacities 19 are provided to neutralize the inductive reactance of the transformer coils. When the receiving-set is placed at the end 3 of the aerial, a coil 15 in the earth lead may be coupled through a phase-adjusting device to the receiver circuit with the object of neutralizing disturbing signals. Figs. 4 and 5 show alternative arrangements for enabling the aerial to function as a transmission line by means of transformers situated at an intermediate point in its length. In Fig. 4, a primary coil 7 is connected in series between the two double-wire sections of the aerial 1, 2, and is coupled to two coils 8 by which currents are induced to flow to the receiving-set round the right-hand circuit 1, 2. In Fig. 5, coils 21 in the aerial wires are so coupled to coils 22 that currents flowing in parallel through the aerial produce additive effects in the closed circuit. Additional coils 23 in the closed circuit induce voltages across the coils 21 which cause currents to flow round the aerial circuit. Two or more closed circuits may be arranged at different points of the aerial each being tuned to the frequency of those signals that are strongest at that point of the aerial. Specifications 190,280 and 191,125 are referred to.

Title: Thermoelectric generator
IPC: H01L35/30
Filed: 1966-04-25
Abstract: 1,090,830. Thermoelectric generators. SANDERS ASSOCIATES Inc. April 25, 1966 [April 26, 1965], No. 18027/66. Heading H1K. [Also in Division F4] A power supply for unattended use at ocean depths comprises an inner housing 107, 108 (Fig. 1) mounted along the central axis of a cylindrical container 11 by a plurality of radial suspension arms 103. The housing contains a heat source 51 and a thermo-electric generator 58 arranged so that substantially all the heat output of the source is directed axially to the hot junctions of the generator and the cold junctions are in good thermal contact with the ocean. In the supply shown, the heat source is a mass of thulium 170 centred in a Dewar vessel 31 which reflects the heat towards a seriesparallel thermocouple assembly 32. The positive thermocouple limbs are germanium-siliconat the hot end and lead telluride at the cold end while the negative limbs have an additional portion of bismuth telluride at the cold end. Both are embedded in epoxy resin at the cold end and quartz fibre at the hot end. The cold junctions are cooled by sea water circulating around anodized aluminium rods held against the thermocouple limbs by springs. Growth of algae on the rods and entrance guides 91 is prevented by impregnating the sintered stainless steel guides and sleeves (98) surrounding the springs (Fig. 2, not shown) with an organotin compound. Since the heat output of the radio-active source decreases with time it is initially in excess of requirements and to avoid overheating the thermocouples sea water is circulated around the heat source by convection through ducts 42, 46 annular space 43 and valve 45. The valve is held open by sodium or zinc vapour from sensor 47 until the heat output falls below a certain level when it closes to prevent circulation. In an alternative arrangement employing latent heat cooling an annular evaporation chamber containing mercury surrounds vessel 27 and communicates with an annular condenser chamber in the wall of housing 11. In this case when the heat output declines below a certain level cooling relies on conduction along the communicating channels and is thus greatly reduced.

Filed: 1943-11-04
Abstract: 572,369. Steam boilers. HINDLE, T. Nov. 4, 1943, No. 18293. [Class 123 (ii)] In a flash boiler of the kind described, for example, in Specification 566,955, which comprises an upper economizer section 7, a lower evaporator section 10, and an intermediate superheater section 15, means is provided for preventing the pressure within the boiler exceeding the normal maximum value due to residual radiant heat in the fuel-bed or fire-box when the steam throttle valve 18 in the superheater outlet pipe 16 is closed and deliveries of feed-water, fuel and combustion air are suspended, as described, e.g., in Specification 571,167, [Group XXXV]. Said means include a water storage vessel 1 which is maintained full and at a pressure substantially equal to the boiler pressure by the fuel pump (not shown) and has an outlet 5 leading to the economizer section 7 which is connected to the section 10 by a down-pipe 8 fitted with a spring-loaded check-valve 11. This valve 11 normally prevents flooding of the sections 10, 15 when the boiler is shut down but is adapted to be opened by an electromagnet 12 if the pressure in the superheater outlet pipe 16 exceeds a pressure of, say, 50 lbs. per sq. inch above the normal maximum steam pressure, actuation of said electromagnet 12 being effected by a switch 29 controlled by a pressure element 28 which is connected by a pipe 36 to the pipe 16. The arrangement is such that during operation of the boiler the feed pump forces water through the section 7 to the section 10, the steam from the section 15 flowing through the pipe 16 and throttle valve 18. When the valve 18, however, is shut, and the deliveries of feed-water, combustion air &c. suspended, any abnormal rise in pressure in the pipe 16 will cause the element 28 to close the switch 29 and energise the electromagnet 12 to open the valve 11 and permit a flow of water through the boiler until the pressure in the latter falls, the steam generated in the meantime passing through a pipe 19 leading from the pipe 16 to a dispersion pipe 21 in the tank 1 where it is condensed and the feed-water therein heated as a consequence.
