Title: Data communication system
IPC: H04L12/423
Filed: 1972-10-06
Abstract: 1356878 Digital transmission closed loop systems INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [14 Dec 1971] 46157/72 Heading H4P [Also in Division G4J In a data communication system comprising a central station and a plurality of remote stations in series in a closed loop the central station comprises means to transmit a first multibit control signal followed by a continuous series of second multibit control signals and each remote station comprises means which responds to said control signals so that the stations which desire to transmit can do so in turn starting with the station furthest upstream and which inhibits transmission from a station once a downstream station has gained control to transmit. The sequence of events is shown in Fig. 3 in which the outputs of the station are shown, the input to a station being the output of the previous station. The central station first transmits framing signals F followed by a control signal (P). The stations which want to transmit, i.e. 1, 2 and 5 generate a signal STX and this appears at the output of the relevant station and any immediately subsequent stations that do not wish to transmit i.e. STX2 appears at the output of 3 and 4. The central control meanwhile continues to transmit framing signals. Only station 1 receives a framing signal after the (P) signal and this station locks in the transmit mode while the others restore to the normal by-pass mode. Station 1 transmits its address A 1, its information T 1 , on end of message or error signal E 1 , a framing signal F 1  and a frame adjusting signal F‹ which restores synchronization between the remote station and control station outputs, if this has been lost. On receipt of the framing signal F 1 , the subsequent stations that wish to transmit again generate their STX signal and this time station 2 and later station 5 lock on and transmit. Remote station construction.-Each station comprises a line terminator 3 in which the line signals are converted to two level binary and which also generates clock pulses. The clock pulses are applied via line 11 to control unit 11. Data not required at the terminal is passed via AND gate 14 and OR gate 15 to line driver 4 which reconverts them to a suitable form for transmission to the next remote station. Required signals are passed through bit destuffer 17 to shift register 18 and passed from there via lines not shown to I/O terminal 16. Output data from the I/O terminal is similarly passed to shift register 18 and then via bit stuffer 19, AND gate 20 and OR gate 15 to line driver 4. The shift register used has eight stages and the framing signal is seven ones followed by a nought. To prevent spurious framing signals occurring in data, the stuffing circuits insert a nought after six consecutive ones and the destuffing circuits remove the digit following six consecutive ones if it is a nought. Recognition logic circuits respond to framing, (P) and address signals in the shift register and the STX and A signals are generated by the I/O terminal.

Abstract: 1,172,909. Yielding friction couplings. SULZER BROS Ltd. 23 Oct., 1967 [21 Oct., 1966], No. 48038/67. Heading F2U. A member 1, e.g. a pulley, chain wheel, or gear-wheel in a loom drive transmission, is frictionally coupled to a coaxial member 2, the friction coupling transmitting normal loads without slip but allowing relative rotation, limited by stop means, between the members when the load exceeds a predetermined value, adjustable springs returning the members to substantially their original relative position when the load falls below said predetermined value. In Figs. 1, 2, studs 3 project from the member 1 through arcuate slots 4 in the member 2, and springs 7 retained on the studs by adjustable nuts act on presser plates 6 to urge friction linings 5 on the member 1 and plates 6 into engagement with the member 2. On overload the coupling slips against the restoring force of Belleville spring stacks 9, tne relative rotation being limited by the ends of the slots 4 and/or the compression of the spring stacks. In Fig. 4, each stud 3 supports a spring 13 which presses a friction cone 11 into an oversize circular hole 4 in the member 2, the springs 13 acting both to maintain engagement of the coupling and to resist relative rotation of the members 1, 2 on overload. In the latter case, relative rotation causes the cones 11 to be moved axially against the springs 13. The limit stop means may be adjustable.

The temperature sensor is a Bourdon tube connected to a temperature sensing bulb. Four cams, arcuate levers and setting levers are mounted on the shaft, each arcuate lever operating a separate switch, and each setting lever can be set individually to a desired temperature. On the end of the shaft is a pointer 17, Fig. 1 (not shown), which indicates the temperature being detected by the bulb on a scale. Each setting lever 39 has a finger 53 on its end which projects through an arcuate aperture in the scale and can be set to a temperature on the scale. Cams 44 can also be set by set screws 45. In a second embodiment, Fig. 6 (not shown), the shaft comprises an inner shaft 57, Fig. 6, connected to the Bourdon tube, an outer shaft 58, Fig. 6, carrying the cams, and a clutch rod 62 carrying the pointer on its end. In the normal position, with the clutch engaged, the shaft turns as a unit and the Bourdon tube operates the cams and switches as described above. When the clutch rod 62 is withdrawn, it is disengaged from inner shaft 57 to free the outer shaft 58 from inner shaft 57. Manual rotation of the pointer will then test the switches by rotating the clutch rod 62 and the outer shaft 58 to rotate the cams and operate the switches.
