Abstract: 1,228,393. Metering pulse generators. SIEMENS A.G. 13 Sept., 1968 [14 Sept., 1967], No. 43559/68. Heading H4K. Metering pulse trains of different repetition rates are produced by coincidence between pulse divisions of a basic pulse train from a generator IG, the divisions being effected as at FU2, FU3, FU5 and FU7 with further divisions at FU4, FU8, and FU9, in the ratios indicated; the output of each divider giving a pulse train the repetition rate of which is not obtainable by coincidence between the pulses of any of the other divider outputs; the outputs of the dividers being selectively connectable as over gates S2 to S9 to a coincidence circuit whereby pulse trains of required repetition rates for metering are obtained at terminal A; the range of repetition rates so achieved being selectively extended into a lower and adjacent range of repetition rates by a further divider such as FUs. A control device ZG operates the gates S2 to S9, and switch US as necessary, to obtain a desired meter pulse repetition rate. The outputs of the dividers FU2 to FU9 can be combined in threes to obtain a reduction equal to the product of the three individual dividing factors, the coincidence of three pulses in the summing circuit SU producing a potential across resistor R which overcomes a threshold detector SW. The outputs of the dividers can be combined similarly but in pairs, a bias being applied to the summing circuit SU over diode GLz from control ZG to provide the equivalent of a third pulse so as to reach the threshold of SW. Each junction to be metered has a separate set of gates S2 to S9, summing network SU, threshold detector SW and further divider FUs. Junctions may also have separate controls ZG but a single control may be used if the gates S2 to S9 are of a bistable character. The generator IG and dividers FU2 to FU9 are used in common by all junctors. To obtain an early metering pulse the divider FUs may be switched in only after the first pulse from SW.

Abstract: 1,252,962. Panel units for lining tunnels; supporting the walls of excavations, or reinforcing roads. J. P. BERNOLD, H. W. PFEIFFER and W. REISING. 8 Jan., 1969 [8 Jan., 1968 (2); 2 Sept., 1968 (2)], No. 1102/69. Headings E1F, E1G, E1H and E1K. A panel member 1 for use in lining tunnels, supporting the walls of excavations, or reinforcing roads, is corrugated and has the crest of at least one corrugation slit at intervals with alternate parts 2d of the crest depressed so that when the member overlaps another like member 2 rod 9 can be inserted between the raised and depressed parts of the crests to hold the two members together. The depressed parts of each member may be depressed as far as or further than V-shaped troughs 3 of the corrugations. The members may be curved along an axis parallel to or perpendicular to the corrugations when used in lining a tunnel. In one embodiment arches composed of hinged sections support the members as they are erected and as concrete which may be vibrated is inserted between the members and the walls of the tunnel. The end arch may have an opening at the top through which the concrete for the top of the tunnel may be inserted. The end of the space between the members and the tunnel walls adjacent the tunnel face is sealed off by a bent portion of one of the members or by a box-like extension on the end arch. If water is to be removed from the tunnel walls gravel, grit or pervious concrete is used instead of concrete and water outlets are placed at the foot of the tunnel. The surface of the members facing the inside of the tunnel may be sprayed with concrete or gunite. A tunnelling shield may be provided and be comprised of a plurality of longitudinally extending lances jointed together by slides extending from an edge of one lance into a slot of an adjacent lance. The lances are advanced by a hydraulic ram engaging in turn teeth on the underneath of each lance. In an alternative embodiment (Figure 27 not shown) a cement mortar containing waterglass is sprayed onto the walls of the members facing the inside of the tunnel and then concrete is pumped through sockets into the gap between the members and the tunnel walls. To support the walls of an excavation (Figures 24-26 not shown) beams are driven in along the perimeter. As excavation proceeds panel members are secured to the beams and are sprayed by concrete which passes through the slits in the members to fill the space between the members and the walls of the excavation. To form a road or runway panel members coated with asphalt or a plastics are laid in rows on the ground with connecting rods 9 coupling the members together. Bitumen macadam is then applied to the units. Alternatively grit and stones are placed on the members and bitumen is then sprayed. The surface is rolled, gritted and re-rolled.

A railway system comprises a train of loadcarrying modules 10 interconnected and driven by drive-units 12 having a pair of motor-driven traction wheels 14 running on rails 16 and guided by guide wheels 22 located fore and aft of each wheel 14 and running on the side of rail 16. Each traction wheel 14 is rotatably supported on a hollow shaft 110 through which projects a drive shaft 84 coupled to the wheel by an end drive fitting 90 and driven by the drive shaft 56 of an electric motor via a high-speed gear train including pinions 68, 74 and a pinion 82 fixed to the shaft 84. The shaft 110 also rotatably supports an idler wheel 106 which, when the train enters a gradient (or section where lower speed is required), runs on an idler rail 108 to lift -the traction wheel 14 of the rail 16 and cause a pinion 64, driven by the drive shaft 56, through a low-speed gear train including pinions 68, 74, 94 and a pinion 96 mounted on a shaft 100 coaxial with shaft 56 and supporting the pinion 64, to mesh with a rack 66 secured to the underside of rail 16. The pinion receives power from the shaft 100 via a freewheeling clutch 104, such that the pinion 64 can rotate faster than the lowspeed gear train. The drive unit may also have a second pinion (150) (Fig. 6, not shown) directly mounted on the shaft 100 to engage a second rack (152) situated at a point further along the track than the first rack such that it is engaged only when the train has been slowed down and is being driven by the pinion 64, to prevent the train from running away downhill. The drive unit may also have a motor-driven cooling fan 116 which draws air into the casing of the motor 64 via ports 122, which air is then exhausted via an exhaust 124 and directed on to a brake disc 120. The drive unit is pin-connected to one adjacent module and connected via a universal joint to the other adjacent module. The system may include sidings positioned vertically from the main track and connected thereto by a pivoting ramp. Further idler wheels may run on the underside of rails 16 such that the train may be run upside down to effect unloading.
