Title: Transfer mechanism for handling mail articles
IPC: B07C3/08
Filed: 1965-01-22
Abstract: 1,042,231. Endless conveyers; sorting postal mail. STANDARD TELEPHONES & CABLES Ltd. Jan. 22, 1965 [Jan. 24, 1964], No. 2892/65. Heading B8A. [Also in Division F2] Letters 2 on a support 1 (Fig. 12, not shown) carried along an inclined channel 79 are picked up by a suction head 12 (Fig. 1, not shown) and deposited on suction retaining endless conveyer belts 4, 5. The latter convey each letter successively to a shoot 13 (Fig. 3) leading to a flight 16 of endless conveyer chains 14, 15. The latter conveys each letter successively past a viewing position and an indexing position and thence to a shoot 20. According to the position of a flap 24 (Fig. 4, not shown) in the shoot 20, a given letter drops on to a closed flap 22 or 23. The flap 24 changes position for alternate letters. The flap 22 or 23, as the case may be, then opens to deposit the letter on one or other side respectively of a position extending along the axis of a conveyer 25. This conveys the letters successively to pockets 34 or 35 (Fig. 5, not shown) alternately according to which side the letters are disposed relative to the partition of the conveyer 25. The pockets 34 or 35, as the case may be, open in turn to drop the letters in succession on to flaps 36, 37, which themselves open to drop the letters into respective pockets of a carrier 40 on a main conveyer 38, 39. The system operates on a time cycle T = 500 milliseconds, this being the time for the carriers 16 on the conveyer 14, 15, to move one step. A motor 41 (Fig. 7, not shown), is connected by a clutch 44, controlled by a relay Xr, with a main shaft 51. This carries cams u, v, w, which respectively control the flaps 22, 23; 34, 35; and 36, 37. Also driven by the shaft 43 is the driving pulley 6 of the belts 4, 5, a one-revolution clutch 52 controlled by a relay Zr, and half revolution clutch 56 controlled by a relay 7r and a coupling 47 to the driving pulley 29 of the conveyer 25. The clutch 47 is able to disconnect its drive on overload (see Division F2), and at the same time operate a switch 76 (Fig. 9, not shown) which de-energizes the relay Xr of the main drive clutch 44. The clutch 56 drives the sprockets 18 of the conveyer 14, 15. The clutch 53 drives a shaft carrying a cam T which operates the suction head 12 (Fig. 1, not shown) and cams P, Q and R which control contacts P1, P2, q and r of a control circuit (Fig. 6, not shown). A push-button I in this circuit is successively operated to forward the letters step-by-step through the system.

Abstract: 420,860. Rotary internal - combustion engines. BISCHOF, B., Winterthur, and ESCHER WYSS MASCHINENFABRIKEN AKT.-GES., Escher Wyss Platz, Z³rich, both in Switzerland. Feb. 3, 1934, No. 3640. Convention date, Feb. 4, 1933. [Class 110 (ii)] The engine has vanes built up of plates 7, 7<1> and between them are arranged plates 8<1>, 8<2>, 8<3>. In the case of a compression - ignition engine, air under pressure is admitted through a port 12, compressed into a chamber 14 and oil is injected into it through a series of nozzles 15. Extra air is admitted through a port 13. Partial combustion takes place, and when a following cell of compressed air, between two vanes, passes the point 14<2>, the combustion is completed. The exhaust gases pass out through a port 11, and scavenging air is admitted when a vane passes the point 121. The exhaust may lead to a turbine. As an alternative process, fuel gas may be admitted through the port 13, compressed and fired in chamber 14 by means of a sparking plug. The inlet port 12 may be replaced by a number of ports displaced angularly, the first port being provided for scavenging air. Cooling water is admitted through a conduit 4 into the hollow rotor, and leaves through a conduit 5. Cooling of the casing is secured by passing water inside a guide-plate 19, the water then being conducted through the rotor and finally being led up the expansion side of the engine following the arrow D. A localized cooling conduit passes through the casing near the point 14<2>. The casing walls vary in thickness on the compression and expansion sides, as shown. The tips of the vanes, which are forced outwards by centrifugal force, are carried by shoes 24 sliding in grooves in races 25 which may be supported on balls or rollers. The vanes 8<1>, 8<2> may be pressed against the end covers 2, 21 by springs or gas pressure. Packing segments 10, between the vanes, may also be spring- pressed or under gas pressure. The inlet and exhaust ports may be formed in the end walls 2, 21. In place of a smooth periphery on the rotor, pockets may be scooped out between each vane assembly. In a modified arrangement the vanes are in one piece, the tips being supported in bushes allowed to rock in sliding shoes. The vanes, which are hollow, may have water hermetically sealed inside, or water flowing through the space.
