Title: Improvements in and relating to hydraulic jacks
IPC: E04G21/12
Filed: 1964-11-17
Abstract: 1,123,233. Wire tensioners. SIMON-CARVES Ltd. (A. Brandestini). 10 Feb., 1966 [17 Nov., 1964], No. 46692/64. Heading F2G. [Also in Division B8] An hydraulic jack for post-tensioning stressing wires 2 of a prestressed concrete structure such as a pressure vessel 4 engages, by means of a coupling sleeve 34, an anchor head 1 receiving the ends of the wires 2 retained by buttons 5, integrally formed at the ends of the wires 2. The coupling sleeve 34 is threaded on to the end of a pull-rod 7 actuated by a double-acting annular piston 8 and ram 13. A load gauge 42 measures the applied load, by detecting small variations in length of a portion of the pull-rod 7 when under tensile stress, by means of two collets 43, 44 held by press fit in a central bore 33 at a known separation. A tube 45 from the collet 43 and a rod 46, passing through the tube 45, are connected to the load gauge 42 to detect differential movement between the collets 43, 44. Thread continuity, with the coupling sleeve 34 in the initial, chain lines, position, between the coupling sleeve 34 and the anchor head 1 is ensured by angular alignment of indented marks 47, 48 on the outer peripheries of a faceplace 17 and a centring disc 29, respectively bolted to the pull-rod 7 and the anchor head 1. Blind holes 49 permit rotation of the pull-rod 7 by a tommy-bar to align the marks 47, 48. Co-axial alignment of the anchor head 1 and the coupling sleeve 34 is effected by means of a centring stud 31 on the centring disc 29. The pull-rod 7 is advanced by pressurizing a cylinder region 11, the thrust being limited by tension springs 41. The coupling sleeve 34 can now be screwed forward by a tommy-bar, engaging blind holes 37, to engage the anchor head 1. The jack may now be pressurized in cylinder region 12 to tension the wires 2, e.g., 163 wires to an overall loading of 660 tons. Chocks (50), (51), Fig. 3 (not shown), may then be placed between the anchor head 1 and a bearing plate 23 of a bearing block 21 and the jack pressure released. The coupling sleeve 34 is then measured from the anchor head 1 and the jack removed from the vessel 4. The bearing block 21 comprises a containing coil 22 of high tensile wire and four fishtail anchorages 25 set in high strength concrete 26 of compressive strength, e.g. 5,000 lb./sq. in. (The main body of concrete of the pressure vessel 4 may have a compressive strength, e.g. of 1,000 1b./sq. in.). The weight of the jack is 3¢ tons. Two jacks, one at either end of the wires 2, may be used.

Abstract: 1,044,580. Digital data stores. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 20, 1964 [Dec. 20, 1963], No. 47295/64. Heading G4C. In an arrangement for reading data from a storage device comprising a plurality of individual stores, each having its own addressing circuit, the addressing circuit of a desired store is selected by a first control signal, thereby initiating a store read cycle, a second control signal independent of the first control signal initiating the output of the extracted data to a utilization circuit. It is thus possible for a computer to communicate on a time-division basis with a plurality of the stores in the storage device. Fig. 1 shows a typical store 1. A first control signal at a terminal 8 sets a " busy " flip-flop 5 if the store is not busy. A gate 12 is also opened to supply the desired address to address register 2 and a monostable circuit 15 is switched to initiate read-out, returning to its stable state on conclusion of read-out from the store 1 to a register 4. Subsequently, a second control signal, on a line 9 sets a flip-flop 6 thereby transmitting the extracted data from the register 4 to an output 32 only after the monostable circuit 15 has returned to its original state. The computer can thus continue with other operations while the data is extracted from the store 1 to the register 4. Selection of the required one of the plurality of individual stores is effected under the control of bi-stable circuits which form part of a full address register common to all the individual stores (Fig. 2, not shown).
