Title: Improvements in and relating to deflecting mechanisms particularly for use in connection with conveyor systems
IPC: B65G47/48
Filed: 1927-12-16
Abstract: 288,231. Lamson Co., Inc., (Assignees of Regan, J. E.). April 9, 1927, [Convention date]. Discharging devices for endless-belt conveyers.-In an endless belt conveyer in which each load carrier is provided with a pin which on engaging an arm suspended in its path causes a deflecting bar to move across the belt to transfer the carrier to branch conveyer, means are provided whereby the bar will be turned into operative position when the arm is swung about an axis transverse to the belt by pins of a certain height, but will remain in inoperative position when the arm is deflected laterally of the conveyer by pins of greater height. The deflecting bar 11, Fig. 1, is mounted on a vertical rock shaft 21 which is connected by a crank 20, link 19, bell-crank lever 17, Fig. 2, link 16 and crank arm 15 to a. horizontal rock shaft 14 arranged above the conveyer and having secured thereto an arm 30, Fig. 4, which depends into the path of pins 48 mounted on the carriers 44. The arm 30 comprises members 35, 33, of which the lower is rotatably mounted on a shaft 34 carried bv the upper so that it can swing transversely to the belt, and the upper is fixed to the shaft 14. The member 35 has a forwardly extending projection 41 provided with a cam surface 42 and a depending rearwardly offset leg 96 in which is slidably mounted a stem 37. A spring 41<1> is placed between the leg 96 and a contact disc 40 on the end of the pin. Rows of sockets 45, 46, 47 of different depths for pins 48 are formed in the carriers 44. If a carrier is to be transferred to the branch conveyer 9, a pin must be inserted in a socket of such depth that the pin only extends sufficiently to engage the disc 40 and does not come into engagement with the cam surface 42. Carriers with longer pins will cause the member 35 to swing about the shaft 34 without displacing the, member 33. The bar 11 may be held temporarily in deflecting position by latch mechanism 27 released by the passage of a carrier over an actuating lever 28 on the branch conveyer.

Title: Method of carrying out heat exchange in a tubular reactor or  heat exchanger
IPC: F28D19/00
Filed: 1971-07-21
Abstract: 1332386 Gas cooling apparatus; steam generators IDEMITSU PETROCHEMICAL CO Ltd and ISHIKAWAJIMA-HARIMA JUKOGYO KK 21 July 1971 [21 July 1970] 34279/71 Headings F4A and F4S [Also in Division B1] High temperature hydrocarbon gas is cooled and/or reacted in an apparatus consisting of concentric-tube elements 3, 7 with an annular space 12 between the tubes of each element, said elements extending through a casing 6, with the inner tubes 3 of the elements extending between chambers 1 and 4, and the annular spaces 12 of the elements extending between chambers 9 and 10 one (as shown) or both of which may incorporate expansion means 11. In use, the hot hydrocarbon gas flows through the tubes 3 via chambers 1 and 4, a cool fluid (e.g. water; which may become converted into high pressure steam) is passed through the casing 6, and an intermediate heat transfer liquid (e.g. molten lead, lead alloy, tin, tin alloy, bismuth, sodium or inorganic salts such as those of mercury or sodium) which need not be circulated, occupies the annular spaces 12 and the chambers 9 and 10. Resinous condensate and/or carbon deposited in the tubes 3 from the hydrocarbon gas is removed by temporarily replacing the intermediate liquid by a gas such as air, helium or carbon dioxide thus rasing the tube temperature sufficiently high for the burning-off of deposits. Burning-off is effected by passing an air stream through the hot tubes preferably after purging them of hydrocarbon gas by means of an inert gas. This method may also be used to remove deposits from catalysts in the tubes 3 when the apparatus is used as a tubular reactor.

Title: An improved method of and means for cylinder lubrication of internal combustion engines
IPC: F01M5/00
Filed: 1946-11-20
Abstract: 640,354. Supplying liquid fuel. STEWART, F. M. Nov. 20, 1946, No. 34366. [Classes 7(ii) and 7(iii)] [Also in Group XXXIV] Cylinder lubrication at starting is effected by lubricant whch is separated from the main supply when an engine stops and is mixed at a progressively decreasing rate with the liquid fuel being supplied to the engine when the engine is restarted. As shown in Fig. 2 the normal supply of liquid fuel is pumped through a pipe 27 from a chamber 4 which has a connection 24 to a supply tank. Lubricant is drawn from a compartment 12 through a pipe 11, a constriction 7 which may be controlled by a needle valve and a port 26 in a vacuum chamber 20. When the engine stops a spring-pressed valve 21 closes and lubricant is stored in the chamber 20 until the pressure on the two sides of the constriction 7 balance. When the engine is restarted, fuel drawn from the chamber 4 is replaced by lubricant from the chamber 20 until the suction is sufficient to open the valve 21, when the mixture becomes gradually weaker in lubricant until normal composition is reached. In a modification arranged to be supplied from a low level fuel tank the connections 24, 28 are arranged at the top of the container and the non-return valve is dispensed with. As shown in Fig. 3 the lubricant supply is cut off after starting. A plunger 39 is normally held up by fluid pressure through a connection 40 from the engine lubricating pump and when the engine stops it falls and draws lubricant from the chamber 12, past a non-return valve 37 into a chamber 35. When the engine re-starts the lubricant is forced past a non-return valve 32, which may be adjustably spring-loaded, into the chamber 4 where it mixes with the liquid fuel which is supplied thereto by pump or gravity.

Title: Improvements in junction working between exchanges in telephone systems comprising automatic exchanges
IPC: H04Q3/00
Filed: 1927-12-20
Abstract: 303,267. Relay Automatic Telephone Co., Ltd., Johnson, B. B., and Inman, T. M. Dec. 20, 1927. Automatic exchange systems.-In systems in which connections from one exchange to a second are effected by selecting a wire common to all the junctions to the required exchange and then completing a circuit over a wire individual to an idle junction, a faulty junction is rendered non- selectable by modifying the appropriate individual wire. The invention is described with reference to a system in which the first exchange is of known type consisting of relays only. In response to the single digit 6, the temporarilyused impulse-recorder connects ground to the common marking wire MW, and battery to the wire 20<a> to identify the trunk circuit OT in use. If the junction J is idle and free from fault, a high-resistance relay HR is normally operated, over junction leads a, b and relay I. A circuit is therefore completed from wire MW over individual wire mwj, relay OJM, and contacts hr1, g1. Relay OJM operates to open the common wire MW and to complete a circuit for relays OT/OJ, SW, which connect the calling end of the trunk OT to the junction J. Relays SH, LE7, operate over the calling loop, the former energizing a holding relay G and the latter shortcircuiting relay HR so that relay I gives a calling signal at the distant (manual) exchange. Relay CE also energizes operating relay S which locks up. When the distant operator replies, relay CE releases and relay OA operates to switch through. When the calling subscriber hangs up, relay SH releases but relay G is held over battery on wire b to prevent release of the apparatus at the first exchange until the distant operator takes down the plug. Alternatively, if the distant exchange is automatic, connection c is broken and d made so that release occurs as soon as the calling party hangs up. If a junction is faulty relay HR is not operated so that individual wire. mwj is open and the next idle link will be seized. In a modification, the high-resistance relay HR is bridged across the trunk and operates over the line-wires in series and battery and earth at the distant exchange.
