Title: Drive chain for infinitely variable cone pulley gears
IPC: F16G5/18
Filed: 1974-11-08
Abstract: 1451856 Chains P I V ANTRIEB WERNER REIMERS KG 8 Nov 1974 [10 Nov 1973] 48555/74 Heaing F2Q In a link chain for an infinitely variable conical pulley gear, link plates 1 each having two bores are pivotally connected, and each link pin consists of two rocker members 2, the ends of which form frictional driving surfaces adapted to engage pulley faces, and the curved faces 5 of which abut in rolling contact, with their flat faces 3 keyed to each link plate 1 respectively by a chordal surface 4 in its D- shaped bore. Included in each link comprising plates 1 and a bracket 6 is a locking plate 7, Fig. 5, which locks the chordal face 4 in one or both of the bores, and which for assembly purposes can therefore be rotated relatively to the plates 1, as shown in Fig. 1. In one bore alone of locking plate 7 there are provided two inwardly-projecting diametrically opposed noses 8, 9, of such a form that they can occupy clear spaces 11, 12, between the rockers 2 when plate 7 is in the rotated position, Fig. 1. Rockers 2 may thus be freely inserted into the link bores when the link members are held in this rotated position, and mechanised assembly operations are envisaged. When locking plate 7 becomes aligned with plates 1, noses 8, 9, engage recesses 10 in rockers 2, thereby preventing the rockers 2 from sliding out through the link bores. When an endless chain is assembled, the last link is not free to be rotated in the manner described, and an alternative locking plate 15, having noses 16, 17, Fig. 6, may be used, and is retained in a locked postion by clinching a tab 18 over adjacent members. An alternative form of rocker (13) Fig. 8 (not shown) has modified recesses which retain it in one direction only, where gravity assists retention, and which also permits assembly insertion of the rocker without rotation of a locking plate 7. Reference is made to Specification No. 1099213.

Title: Data transmission controller
IPC: H04L12/00
Filed: 1963-12-17
Abstract: 1,072,490. Electric selective signalling; computers. GENERAL ELECTRIC CO. Dec. 17, 1963 [Dec. 27, 1962], No. 49836/63. Headings G4A and G4H. A remote station is selected for connection to a central station by driving a counter scanning the remote stations until it has the desired reading as determined by a comparison, data being transferred between the stations, which have different pulse rates of operation, via storage means adapted to receive and transmit at the operating pulse rate of the respective stations. A computer can communicate with any one of 16 locations, these consisting of 15 remote stations and a paper tape reader/punch. The locations are scanned cyclically by a binary scan counter driven by computer clock pulses. When the computer requires to transmit information to a location, it stores the address of the location in a four-bit register for comparison during scanning with the count in the scan counter. On equality being reached, delivery of clock pulses to the scan counter is terminated, and the computer is signalled. The computer then passes the first character in parallel mode into a shift register from which it is read-out serially to the selected location by shift pulses, these being derived from the computer clock pulses by reducing their p.r.f. (by means of a counter and a gate-decoder, Fig. 3, not shown). However, parallel to serial conversion is not performed if the selected location is the reader/punch. Further characters are read-out of the computer memory in the same way, an address counter and a character counter keeping track of the address in the computer memory the current character comes from and the number of characters read-out respectively. If a location requires to transmit information into the computer memory, it energizes its respective communication line. When the scan counter scans that particular line, a signal is sent to the computer. If the computer signals that it is ready, the location transmits its information which is fed into the computer memory, after serial to parallel conversion in the case of the remote stations. Each remote station has a keyboard for input and a typewriter for output. A mode change counter provides a delay between operation in different modes (transmit and receive) to allow the circuits to adjust, the delay being greater when the reader/punch is involved than when not. Patch plugs are provided at the parallel input and output of the shift register for digit interchange &c. The computer continues operation except when actually transmitting or receiving a character to or from the shift register. Start and stop bits are provided with each serial character. A decoding circuit is provided connected to the stages of the shift register to recognize special control characters (e.g. " end of message "). After reception of a complete message from a location, a programme interruption is effected in the computer.

Filed: 1966-11-17
Abstract: 1,142,391. Direct contact steam generators. COMBUSTION ENG. Inc. 17 Nov., 1966 [17 Dec., 1965], No. 51650/66. Heading F4A. [Also in Divisions B1 and F1] In a system for the distillation of saline water and the generation of power, steam is circulated by compressor 14 through a cycle including a superheater 12 and an evaporator 18 wherein preheated saline water is contacted with the superheated steam so that at least part of the water is evaporated, some of the steam is withdrawn from the cycle through conduit 26 and, after being superheated in heater 28, is employed to produce power by expansion in multistage turbine 32. The steam discharged from the low pressure stage LP of the turbine flows to condenser 34 which is cooled by indirect heat-exchange with saline water, part of which then flows through a series of open heaters 48 to evaporator 18. The condensate formed in condenser 34, i.e. purified water, is collected in tank 36. Excess saline water over and above that necessary as feed for the evaporator 18 is directed from condenser 34 through conduit 44 back to the source. The exhaust steam from the high pressure turbine stage is reheated in heater 28 and conveyed to the intermediate pressure stage and then to the low pressure stage of the turbine. Part of the reheated steam from heater 28 is, however, employed in turbine 15 which drives compressor 14. The exhaust from turbine 15 is conveyed through conduit 17 to condenser 34. In the open heaters 48, the feedwater is contacted with steam which is bled off from turbine 32. The preheated and diluted saline water from the last heater 48 is then sprayed into evaporator 18 where all the water is vaporized, so that a mixture of dry salt and steam flows into separator 20. In an alternative arrangement, a quantity of concentrated brine is maintained in evaporator 18, and the superheated steam is introduced below the liquid level.
