Title: Tdm transmission of asynchronously occurring binary data
IPC: H04L5/22
Filed: 1975-05-21
Abstract: 1515694 T.D.M. transmission of asynchronous data SIEMENS AG 21 May 1975 [6 June 1974] 21975/75 Heading H4M In an arrangement for the t.d.m. transmission of binary data occurring asynchronously relative to the multiplex timing, each change of binary value in a data stream to be multiplexed is assigned a pulsed telegram comprising several bits, representing the binary value change and its position in the multiplex frame. The data on each channel to be multiplexed, e.g. A/l, is fed to a binary value change discriminator PL. This responds to a periodic scanning signal H, whose period corresponds to a timing raster for determining the time position of the binary value change in the multiplex frame, next following the occurrence of a change, to emit a write-in command pulse K for each binary value change which it detects. This pulse resets a register SR 1 to zero, and immediately the binary values for the appropriate pulse telegram are written into this register, representing the time position (first two digits S, S 2 ) and direction of this change (third position S 3 ). The register is read out to the multiplex highway L by a timing pulse train B, synchronised with the multiplex frame. The pulses in this train are counted (register SR2) from the time of the write in command pulse K (applied to input C of SR2) until the count reaches a predetermined value, determined by the size of the register. During this counting time gate GT2 remains closed so that timing pulses E cannot be applied to scan the change discriminator PL. This ensures that the telegrams obtained from SR1 will not be mutilated by a change in state from the discriminator PL before they have been completely formed. Such an arrangement (KS/1) is associated with each input data stream to be multiplexed (Fig I not shown) and timing waveforms B-F (Fig 4 not shown) supplied to all such arrangements from a source SS. Instead of the shift register SR2 shown in Fig 2, a triggered counter may be used (Fig 3 not shown).

[Also in Division F4] In a mechanism for operating alternatively one or other of two dampers 7, 9 in a heating/ cooling unit (see Division F4), each of two levers 13, 14 has one end connected to a respective one of the dampers and the other end engaging a respective cam slot in a disc 15 rotatable by an actuator 18. The cam surfaces 21, 22, 24, 25 are so formed that with the disc 15 in one position both dampers are closed, and rotation of the disc from this position clockwise (Fig. 2) opens the damper 7, damper 9 remaining closed, while rotation anticlockwise opens the damper 9, leaving damper 7 closed. Surfaces 21, 24 are arcs centred on the axis of rotation of the disc 15. The actuator 18 may be a double-acting pneumatic ram acting via a connecting rod 19, or an electric actuator.

An airship comprises a double walled outer envelope 1 enclosing flexible invertable walls 3a, 3b, 3c forming chambers 37, 43, 41, 45. The chambers 37 contain said inflammable gas; chambers 43 contain saturated water vapour; chambers 41 contain cold or heated air and are used as compensation chambers, and chambers 45 store a gas, e.g. carbon dioxide and/or nitrogen and air for filling the space between the two walls of envelope 1. A centre chamber 39 contains buoyant gas. The airship is propelled by a main blower 33 which discharges a propulsion jet through nozzle 9 and a blower 31 provides propulsion under slow speed conditions, directional control being provided by vanes 13a. In operation inflammable gas from chambers 37 and water vapour from chamber 43 are delivered to a catalyst apparatus 60 where they are reacted and the product gas is supplied to chamber 39. Exhaust gas in duct 47 from blower 33 is passed through apparatus 60 where it is heated and then passed to condenser 57 to condense out water vapour.

Class 135 A fluid flow control device in a pneumatic control system comprises a tube of flattened cross section, similar to Bourdon type tubing, which is automatically bent in response to a control signal to vary the restrictive effect of the tubing and so control the fluid flow therethrough. In an embodiment, the fluid to be controlled flows through two curved and flattened tubes 49 which are connected in series by a further flattened section 50 positioned on a bobbin 51. The latter is connected by a link 12 to the closed, movable end of a bellows 13, and the latter, with a casing 14, defines a chamber into which a control pressure can be applied through a conduit 21. The bellows is loaded by a spring 36 and its travel is limited by stops 34, 31 which are carried on a spindle projecting from the top plate of the bellows and co-operate with the top and bottom, respectively, of a sleeve 28. A cap 29 and sealing washer 30 keep the casing airtight. Air is led into and away from the tubes 49 through straight tubes 48, the latter passing through and being adjustably held in, a bar 43 by means of a clamp nut 47. The bar 43 is adjustable in slots 46 in arms depending from the base plate 19, and this adjustment, together with the previous one, constitute zeroizing adjustments. By rotating bar 43, the proportional relationship between the movement of bellows 13 and the amount of bend in tubes 49 may be varied.

As shown, the stressing element 2 is wedged into an annular block 4 having a recess 8 in which the end of the tube 7 is positioned. A nut 15 on the tube transmits the prestressing force from the annular piston 13 of the main jack 120 to the element via the block 4, and a second nut 16 is tightened against a transom 20 of the body portion to retain the stress, the jack 120 is retracted, and the first nut tightened against the jack again; this sequence is repeated until the required tension is achieved, whereupon the annular piston 11 of the auxiliary jack 10 is actuated to drive home an anchoring device. In the alternative embodiment (Figs. 2-4, not shown), the end of the stressing element is wedged into an annular connector 60; into the other end of which a rod 55 is screwed, thereby clamping the three-segment wedge 62 against the stressing element. In this embodiment a modified, but similar form of auxiliary jack is employed.
