[Also in Division A4] A conveyer system comprises a plurality of individual conveyers 2... 2c for selectively feeding articles from a primary conveyer system 1 to individual stations 26 . . . 26c and an electrical control system for selectively setting in operation the primary conveyer system 1 and any of the individual conveyers 2... 2c, the primary system 1 comprising a plurality of conveyer belts 3, 4a ... 4c, in series separated by bridging sections 5, 5a ... 5c. As shown, the system conveys strips of tread material 38 to tyre-making machines 21 ... 21c and the primary conveyer system comprises conveyers 3, 4a, 4b, 4c with intermediate pivoted bridges 5, 5a ... 5c, which can be either horizontal to interconnect the conveyers 3, 4a . . . 4c, or can be swung down to connect any primary conveyer to an individual conveyer 2... 2c. The conveyer 2 ... 2c each comprise a pair of belts which grip a tread 38 therebetween and convey it to a tray 15... 15c which, after receiving the tread, can pivot about its right-hand end to deliver the tread to its machine 21 ... 21c. In the normal condition, the primary conveyers are stationary and each has a tread 38 thereon at its righthand end in contact with trip switches 28a, 28b. Each bridge 5 is controlled by a pneumatic device 9 with control valves 11, 12, and when horizontal the bridges are retained by solenoidoperated latches 13 which have associated switches 30. . . 32 controlling valve 11. A further switch 35 closed when the bridge 5 is in its lowered position controls the motors 8, 20 driving the conveyers 3, 2. If, for example, a tread 38 is desired at station 26, switch 33 is pressed which actuates the solenoids to withdraw latches 13 of bridge 5, which closes switches 31 to actuate valve 11 and operate the device 9 to commence lowering of bridge 5 and closes switch 32 to hold the latch solenoids energized. When the bridge 5 is completely lowered it closes switch 35 which energizes motors 8 and 20 so that a piece of tread is fed from the preceding primary conveyer 3 on to conveyer 2. When the tread reaches tray 15 it breaks a switch 36 which switches over valves 11, 12, so that bridge 5 is raised, thereby breaking switch 35 to switch off motor 20. Motor 8 remains energized, however, until a fresh piece of tread material on conveyer 3 reaches trip switch 29 which cuts out motor 8. If, however, any of the other succeeding conveyers have also fed their pieces of tread to their associated machines the trip switches 27a, 28a, 29a, &c. associated therewith keep the primary conveyer motors 8 . . . 8c energized so that fresh pieces of tread material are fed along the primary conveyers until each conveyer is replenished. The operation is the same for all the stations.

Abstract: 388,610. Fluid-pressure power plant. GES. FœR LA MONT-KESSEL UND KRAFTWIRTSCHAFT (VORM. TECHNISCHE ZENTRALE DR HERPEN GES.), 1B, Schadowstrasse, Berlin. May 18, 1932, No. 14189. Convention date, May 20, 1931. [Classes 110 (iii) and 122 (iii).] Apparatus for generating high-pressure vapour from liquids such as water, mercury, &c., comprises a rotary, two-limbed generator which is driven at speeds which determine the vapour pressure developed against the action of centrifugal force. The vapour generated may be expanded in a turbine mounted on the same shaft, or in an engine connected to the generator. In the construction shown in Fig. 6 a two-limbed system of tubes 1, 2 is mounted on the hollow shaft 6. The liquid to be vaporized passes from the container 4 into the right-hand part of the shaft 6 to the limb 2 of the tubes 1, 2 which are connected by longitudinal tubes 11. From the centre of the shaft the fluid passes through the superheater tubes 13 to a shaft 6 and thence to the turbine where the vapour expands from the middle either in an axial or radial direction. The speed is regulated by regulating the furnace fuel supply through the burner 16. The amount of liquid supplied to the generator is dependent upon the temperature of the vapour generated. The apparatus may be started by a starter, or by supplying vapour from an external force. In the arrangement shown in Fig. 7, the rotary generator is associated with an ordinary boiler installation. The exhaust gases from the combustion chamber 20 pass through a pipe 21 into the generator 22 and then back through pipe 23. The vapour drives the engine 15 the exhaust from which passes through a coil 25 in the upper drum wherein it is condensed and led back to the generator 22. Steam or mercury vapour may be generated in the primary generator 22, and the heat from this in condensing generates steam in the installation 27 which is utilized in an engine 28. The aggregate may drive a generator 29. Water may be heated for heating purposes instead of a secondary vapour generated. An arrangement is described wherein the heating coil .13, Fig. 6, is dispensed with.
