Title: Improvements in or relating to suspension bridges
IPC: E01D19/14
Filed: 1939-04-08
Abstract: 528,466. Suspension bridge; ground anchors. DORMAN, LONG & CO., Ltd., PAIN, J. F., and FREEMAN, R. May 8, 1939, No. 13683. [Class 20 (i)] [Also in Group I] The wires of each row which form a composite cable for a suspension bridge are carried simultaneously across the span maintaining a predetermined positional relationship, and the tension in the cable is controlled by exerting a restraining force on the cables during their movement. The wires for the cables are: carried by drums mounted on rotary turntables (not shown) and are led in rows, simultaneously therefrom, through guides and tensioning devices, a number of rows being superposed, each row being compacted at the ends and having a separate anchorage. The wires for each row are led through grids 12, then through spacers 20, 21, over the lower members of roller tensioning devices 15 with spacers 19 between each set of rollers, through a further spacing device 21, thence over a rubber faced block 36, around a guide roller 37 and the ends are attached to a spreader frame 38, Fig. 8, the wires being then tightened by rotating the turntables backwardly.. The upper roller frames, upper members of the spacers, and upper blocks 35, are then placed in position and the tensioning device 15 adjusted, whereupon the spreader frame is drawn forwardly some distance, the formation of the wires between the spreader frame and the guide roller being maintained by loose clamps at intervals. The ends of tHis row of wires are then compacted into a cable by means of a cramp comprising two bifurcated members 51, 53, Fig. 9, capable of adjustment by screws 52, bound with soft wire, and secured in a socket 6. This socket is then drawn across the span by a haulage rope, the wires resting on nests of rollers, adjustably connected to the bridge towers, the loose clamps being removed and refitted when passing the towers, and the sag of the wires being set by a pilot cable and controlled by the adjustable pressure device 15. The socket is then drawn over an anchorage strut 5, Fig. 10, and attached to its allotted anchorage wire 7, which is secured to a plate 8 embedded in concrete, the wires are arranged on the saddles of the towers in their correct positions, the sag finally adjusted and thereupon the ends of the wires between the turntables and tensioning devices 15 are compacted by the cramp 51, 53, cut, bound, and fixed in a socket and after removal of the tensioning device connected to its anchorage. The operation is repeated for each row, the rows being superposed on the saddles of the towers to form a composite cable as shown in Fig. 15, this cable comprising forty rows. The spacer 20, Fig. 6a. comprises a lower apertured plate 29 to support rollers 32 and a slotted upper plate 28 adjustably fixed to the lower plate. Each spacer 21, Fig. 7a. comprises upper and lower plates 22, 23 joined together at their ends, and provided with a gateway through which the wires are passed, this gateway being closed by a projection 27 on a lever 26.
Patent GB-881016-A (GB)
Title: Improvements in or relating to magnetic selection apparatus
Filed: 1959-04-22
Abstract: 881,016. Electromagnets. BURROUGHS CORPORATION. April 22, 1959 [May 5, 1958], No. 13735/59. Class 35. [Also in Group XIX] A shoot selector for a cheque or record 22, Fig. 1, comprises a number of movable blades 16, 20 of non-magnetic material between adjacent pairs of which shoots are defined to different sorting pockets, coils 24 being mounted on the blades to establish opposite magnetic poles on opposite faces of the blades and fixed permanent magnets 10, 12 for attaching or repelling the blades so that according to the energization of the coils, a shoot is opened to receive the check or record between a selected pair of blades. The magnets 10, 12 are arranged with similar poles opposed and the coils 24 are spirally wound wire or etched or printed coils. Connections 26, 28 from the coil are made to terminals 30, 32 on the stationary part of the blade. The coils may be secured to the blades by adhesive and the blades may be made of any non-magnetic metal such as beryllium copper alloy or of a plastic. The coil may be sandwiched between two plastic layers. The coils are energized in two sets, one set being magnetized in one direction and the other oppositely magnetized so that the two sets of blades move towards opposite sides and present the desired shoot open in between. The upper and lower blades together guide the cheque 22 to the desired pocket. To open a shoot between another pair of blades it is only necessary to displace the intervening blades as shown in Fig. 3, by changing the polarity of their coils. The other blades remain in their positions. The blades are loosely mounted on transverse pins between guide plates 52, 53 which limit their movement. The cheques are fed through the sensing station and along the selected shoot by an endless belt on one side of the cheque and rollers on the other. The belt and rollers engage the cheque through the gap between upper and lower packs of blades. Control circuit.-For each blade in the upper pack and its associated blade in the lower pack there is a separate control circuit 120, Fig. 9. According to the digit sensed on the cheque one of the input lines 46 is energized by a voltage different from the others. Initially all the outputs 40 deliver a similar current so that all the blades are displaced to one side. If a negative voltage is applied to one line, the output line 40 of that line becomes negative and the current in the blade coil is reversed. Each circuit has a cross-connection from point 134 to the input of the next circuit on one side so that when the output of any circuit becomes negative it provides a negative input to the next circuit and reverses the current in the corresponding blade coil. The currents in all the blade coils on one side of the selected blade are therefore reversed and the blades divide into two sets as described above.

Title: Dual pump system and control valve assembly therefor
IPC: E02F9/22
Filed: 1961-04-17
Abstract: 911,053. Shovelling machines. PARKERHANNIFIN CORPORATION. April 17, 1961 [April 18, 1960], No. 13782/61. Class 68 (1). [Also in Group XXIX] A fluid power system for a back-hoe on a tractor comprises at least two pressure-operated units 19, 20 which are associated with control valves 28, 38 and operated by fluidpressure delivered by respective pumps 23, 24 so that one unit 20 may be operated by the conjoint discharge of both pumps when the other unit is not in operation, an unloader 80 for the pump 24 associated with the said one unit when the fluid-pressure delivered to that unit exceeds a predetermined value, a first check valve 68 downstream the unloader to maintain such fluid pressure in said one unit when said one pump is unloaded, and a second check valve 63 permitting flow of fluid under pressure from the other pump 23 to said one unit for continued operation of the latter. The tractor may have six units consisting of right and left stabilizers 7, 8, a swing cylinder 19, a boom hoisting and lowering cylinder 20, a crowd arm cylinder 21 and a bucket cylinder 22. The units 7, 8 and 19 may be of small capacity and are controlled by valves 28, 29, 30 which connect the small capacity highpressure pump 23 to lines 31, 32, 33 leading to the units. The units 20, 21, 22 are of large capacity and controlled by valves 38, 39, 40 which connect the large capacity low-pressure pump 24 to lines 41, 42, 43 leading to the units. When any of the units 20, 21, 22 are in operation and the resistance against movement is low, the output from the high-pressure pump acts through a by-pass 61 and check valve 63 to be added to the output of pump 24. As the resistance to movement of the unit increases, the pressure at the inlet 67 from the large capacity pump 24 acts on a portion 81 of the unloader 80 which is moved to connect the output from the pump to a return passage 78 connected by a line 52 to a reservoir 53, the unit then being operated by the high-pressure pump 23 only. Check valves 73, 74 are provided to prevent back-pressure from the units acting on the system. A relief valve 79 limits the maximum pressure from the high-pressure pump 23.

Title: A method and apparatus for closing or sealing cartons and the like
IPC: B65B7/20
Filed: 1932-05-13
Abstract: 403,078. Closing cartons &c. HARTMANN, C. W., Lyngby, near Copenhagen. May 13, 1932, No. 13821. [Classes 18 and 94 (i).] A carton &c. which has been closed by having its closure flaps folded inwards and down is subjected to a final closing and sealing pressure by measuring a ram 10 during which process ribs 17 are pressed into the wall of the carton &c. just beneath the top to support the pressure of the ram 10 and to form a rib in the carton. The ram 10 is slidable without rotation in a plate 13 sliding on uprights 3 and is moved upwards or downwards by a screw 12 on a spindle 8 rotating in a bearing 7 in an adjustable cross-bar 4, movement being effected from a handle 9. The ribs 17 are pivoted to a cruciform plate 21 with bosses 22 which slide on the uprights 3. The plate 13 is moved down by cam surfaces 24, 25 shaped or shown in Fig. 6 so that initial rotation of the spindle 8 passes the plate 13 downwards but further rotation does not further move the plate. This movement of the plate 13 rotates the ribs 17 about their pivots and forces them into the sides of the carton &c., further movement of the spindle 8 applying the sealing pressures. On reversal when the cores permit plate 13 to move upwards under the pull of spring 29, the ribs are pulled out of engagement by the action of springs 32 which press apart the plates 13, 21, after which projections 33 on sleeves 14 of the plate 13 engage with the sleeves 22 of the plate 21 so that the ribs are moved upwards with the ram. The carton &c. is positioned by means of guides 35 at top and bottom.

The lock is raised by the electromagnetic means described in Specification 161,694.
Patent GB-139609-A (GB)
Abstract: 139,609. Joy, B. C. March 1, 1919. Vacuum obtained by explosion of gases.-A partial vacuum is created by the explosion of a gas in a closed chamber and the ejection of the products, for the purpose of dust removal and vacuum cleaning, by the employment of a chamber of considerable length, with inlet and outlet at opposite ends and with automatic ignition means; the admission of gas may be delayed until some air has been admitted. As shown, the explosion chamber a is arranged within a water jacket b and provided with an inlet tube c and a valved outlet tube d connected with a long exhaust pipe d<1>, which may be provided with a silencer. Near the top is a valved pipe connexion f to a bellows or pump by which an initial charge of gas and air may be drawn in. Near the bottom is an igniting-device comprising a thin sheet of metal m with a small perforation through which passes the flame of a Bunsen burner provided with a guard. The casing of the water jacket constitutes a boiler from which hot water may be drawn off for domestic purposes. The inlet pipe c communicates with a mixing- chamber to which air enters past a valve w through a pipe connected with the dust chamber or separating-device of the vacuum cleaner. Gas enters the mixing-chamber through ports x and a screen of gauze &c. y from a pressure-regulating bag 11 in valved connexion with the gas supply. After each explosion, the combustion products are driven out through the exhaust pipe, and the cooling of the cylinder produces a partial vacuum. The air-inlet valve is closed by the explosion, and part of the combustion products are driven back into the gas-supply pipe. Consequently, the vacuum first draws air in along with combustion products, and afterwards a mixture of air and gas.

Title: Electrical plug and socket connectors with retractable contacts
IPC: H01R13/453
Filed: 1943-08-27
Abstract: 582,939. Two-part couplings. MODREY, H. J. Aug. 27, 1943, No. 14013. [Class 38 (i)] A plug or socket member has the contacts retracted by spring action when not engaged with its counterpart, and projected by the relative axial approaching movement in the action of plugging in the coupling, which action also effects the locking of the coupling members together. In one construction the contacts 5 are carried by a disc 4 attached to the cable casing 10 and slidable within the shell 1 so that the contacts 5 pass through the body 12a into which they are retracted by springs 14. The locking device is of the kind described in Specification 561,043 and comprises a rod 8 having a head 8a co-operating with a stud 15 the latter being secured in a casing 16 that slides in the body 12a as far as a rib 16a will allow. When the casing 10 is pressed down to plug the member 1 into the socket 20, the pins 5 are projected into the sockets 22 and the head 8a enters a floating bush 32 which afterwards receives the stud 15 which with the rod 8 fills the hole in the bush and prevents the return of the head 8a. On withdrawing the plug member by a pull on the shell 1, the body 12a acting on the rib 16a withdraws the stud 15, compressing the springs 14, 18 so that as soon as the stud 15 leaves the hole in the bush 32 the head 8a springs out of the bush 32 and the pins 5 snap out of the sockets 22. The rod 8 and bush 32 may constitute electric contacts. The arrangement may be modified by making the socket elements retractable and the plug pins stationary.
