IPC: G05D1/02
Filed: 1969-03-03
Abstract: 1,264,401. Leader gear systems. ROBERT BOSCH G.m.b.H. 3 March, 1969 [2 March, 1968], No. 11107/69. Addition to 1,263,993. Heading H4U. In a system of the type disclosed in the parent Specification in which the vehicle carries a pair of pick-up coils in which the induced voltage and phase relationship indicate the deviation of the vehicle from an energized conductor to control the steering, the pick-up coils are coupled to respective tuned amplifiers which are selectively switchable to different resonant frequencies by signal transmitters located at control points of the track network whereby the vehicle follows a conductor energized at the selected frequency. The signal transmitters may be magnets arranged at branching off points and similar devices may be arranged to stop the vehicle or to effect loading and unloading. An arrangement is described in which a series of adjacent or partially overlapping conductor loops are each energized with a different frequency and a predetermined selection of the conductors to be energized determines the route. Where a vehicle has to cross an intersecting conductor energized at the same frequency as the one being followed, switching devices operated by a transmitter on the vehicle are arranged to interrupt the intersecting cable and insert a length of screened cable at the cross-over point to prevent distortion of the magnetic field of the conductor in use. Alternatively, a bar magnet may be arranged to extend across the intersection to actuate a control device causing the vehicle steering to be locked while it passes over the intersection.

Abstract: 1288737 Data transmission systems SIEMENS AG 8 Dec 1970 [9 Dec 1969] 58152/70 Heading H4P Clearing signals on any of a number of data transmission lines L are detected by counters located in and allotted by a central control unit Zst. Each line L is associated with a respective unit M1-Mn, the detectors being enabled sequentially and cyclically by pulses on lines DL from decoder D in response to a series of line. address signals generated by unit AG when clock pulses H are applied to it. When a detector is enabled by DL it stores the present signal state of the line. If this state is clearing signal potential and if this potential is still present when the detector is next enabled by DL, the detector passes a signal over line S causing the central unit Zst to allot to the detector a pulse counter. At each subsequent instant that the detector is enabled the counter is incremented if the clearing signal potential is still present. If a certain count is reached the presence of a clearing signal is confirmed and the unit Zst breaks down the connection. Unit Zst similarly allots a counter to each detector M associated with a line having clearing potential. Central unit Zst includes a store having a number of cells. When a detector calls for a counter to be allotted to it one of the cells is seized and filled with the corresponding line address from AG and with the present count. The seized cells follow one upon the other in order of decreasing address. When a pulse is received over line S the address of the corresponding line is compared with the top-most address in the store. If the addresses are equal the count is incremented and the address and new count stored at the end of the block of seized cells, the highest cell being erased. If the stored address is less than the line address a new cell is seized immediately following the seized block, and the address and count (= 0) is stored there. If the stored address is higher than the line address the stored address is erased. The number of free cells and the ordinal number of the topmost seized cell are stored in registers.

Staple bending depressions 57 are formed, in the outer peripheral surface of the supports and are aligned with radial slots in the stapling member from which the staples are sutured into the vessel, and semi-rings 39 turnable within the arcuate stapling members have grooves 42 which engage the ends of shanks 43 so that when the semi-rings turned, the shanks are forced radially inwardly to eject a staple, from its radial slot. The supports are attached, by means of bars 23 to elongate members 4 and 22, respectively, Fig. 4 and the stapling members 10 by bars 12 to elongate members 5 and 11, the former of which accommodates a rod 44, longitudinally adjustable by means of a thumbscrew 45 at one end. The other end of the rod 48 engages a shank 49 fixed to a semiring 38 and movement of the rod causes the shank 49 and semi-ring to turn, whereby shanks 41 are moved radially inwards by grooves 40 in the semi-ring 38, until a staple engaging the shank 41 is moved into abutment with the vessel to be sutured. A lever 51 is pivotable about a screw 52 to turn the semi-ring 39 by means of the interaction of teeth 53 at the end of the lever and rods 54 fixed to the semi-ring 39, and thereby eject the staples. A stop 60 on the movable rod limits the movement of the lever 51 and thus the movement of actuators pushed by the rods 43 to eject the staples.

Filed: 1969-09-30
Abstract: 1330636 Moulding prestressed concrete FLOWCRETE Ltd 22 Sept 1970 [30 Sept 1969] 47975/69 Heading B5A In an apparatus for continuous production of prestressed concrete, fluent concrete is fed on to a moulding conveyer 10 from a casting unit 29, the conveyer drive drum 28 being operated synchronously with a pretensioned wire feed drum 37 so that pretensioned wires 31 are fed at the same linear speed as the conveyer 10. The speed of the conveyer may be regulated to ensure that the concrete product 20 has set by the time it reaches a predetermined position with respect to an output location on the conveyer. To form the product 20, a crosshead 33 (Fig. 1) is initially used by means of which a closed loop of pretensioned wire is obtained, passing from reels 32, along the outside conveyer to pulleys 35, back under the conveyer, on to the feeding drum 37 through a guide 36, and from there to the crosshead 33, the wires being tensioned by means of hydraulic jacks 39. A length of concrete is then east around the wires, the crosshead moving with the conveyer, and the product allowed to harden, the conveyer remaining stationary, until it has achieved the desired strength for stress transfer, when the jacks 39 are released allowing the hardened concrete to hold the stress in the wires 31, thus prestressing the concrete product. The crosshead may then be removed and the cycle repeated or, for continuous operation, the product and outer reinforcing wires 31 are threaded through two advancing devices 40, 40A (Fig. 3) having clamps 41 for gripping the concrete product and wire gripping jacks 42, 42A. The advancing devices are hydraulically operated by jacks J1, J2 and are movable longitudinally of the conveyer. The clamps 41 and wire gripping jacks 42, 42A are hydraulically operated. To advance the product along the conveyer during casting, the advancing devices are moved towards each other, the device 40 gripping both the product and the reinforcing wires. When the two devices are adjacent, the device 40 trips a switch 44, causing the device 40A to grip the product and wires, itself being released, the two devices then moving away from each other until the device 40A trips a switch 44A, causing the device 40 to grip the product and wires and releasing the device 40A. The devices then move towards each other again. Thus the devices together serve to advance the product towards the output end of the conveyer and allow fresh wire into the system under tension. The whole control system for operating the devices 40, 40A is hydraulic. Also described (Fig. 2, not shown) is a conveyer in which the conveyer belt (15) is supported on a water film, which may be heated to assist curing of the concrete. The whole conveyer is mounted, in this case, in an insulated, covered trough (11).
