The two blades are arranged such that one deflects the cable coils during wind in and the other deflects the coils axially of the drum during pay out. Each blade 2 is articulated at its ends to slides extending parallel to the drum axis, one articulation joint permitting rotation only whilst the other joint permits a degree of sliding along the length of the blade. Each slide is movable in the direction of its length, to move the blade axially of the drum, by use of hydraulic rams 23, 27 and 24, 28 reacting against fixed structure walls 25, 26. The pressure of fluid in the rams is indicated on gauges at a control station so that the positions of the blades may be changed to spread the cable side thrust evenly along the appropriate blade. The inclination of each blade is also indicated at the control station, the movement of each end of each blade transmitting linear movement to a wire to which one end of an indicating arm is secured.

Apparatus for producing such sandwich structures comprises conveyors 70 and 72 defining upper and lower travelling surfaces, a curing zone such as an oven 74, means for feeding facing webs 22 and 30 into contact with said travelling surfaces, a planar support 20 for the first web, means for bringing the other web into spaced parallel relation with the support, a mixing or spray head 35 having a discharge nozzle 36 for applying self-foaming resin mix across at least one of the webs, a reciprocating carriage 38 and bridge 40 for supporting the mixing or spray head and a trolley 50 for moving the support means longitudinally to vary the position of lay-down of the resin mix, and nip-forming means (q.v.) such as roller 54 extending across the planar support, at least one member of the nip-forming means being adjustable with respect to the other to vary the nip gap. The apparatus may additionally comprise side trimming and cutting stations to produce standard panel lengths. The nipforming means may comprise a roller 54 on a shaft 55 which is supported by arms 56, each arm being pivotally mounted on a movable block 58 which can be clamped in a desired position. The roller may be adjusted vertically by means of wedge blocks 60 each carried on a slide 61 and shiftable by means of a feed screw 63 or may be power-lifted by an hydraulic jack 64. In a modification, the nip may be formed by a flat plate (Fig. 7) adjustable vertically by means of screw jacks, an idler roller being used to bring the second web contact with the resin mix. The carriage 38 is reciprocated on tracks (42) of bridge 40 by means of an hydraulic ram 44 to provide a generally sinusoidal path of liquid resin lay-down. The reciprocation speed of head 35 is changed during the cycle, to produce a variable lay-down of resin, by means of a solenoid controlled valve placed in the hydraulic supply line, the valve being provided with one or more restrictor means operably connected to limit or trip switches (41) which are adjustably preset along the tracks (42).

[Also in Division G4] An automatic beverage dispenser includes switches A-F for selecting the beverage to be dispensed and interlock means for preventing the manual operation of more than one switch A-F at a time, the switch C being linked with the other switches A, B and D-F whereby manual operation of one of said other switches also closes the switch C. Additional switches G and H are provided and may be operated in addition to one of the switches A-F to dispense extra cream and/or sugar. The switches consist of spring-loaded push buttons 60 mounted in a channel member 14. Each push button co-operates with a pivoted latch plate 140 terminating in an extension 146 engaging a draw bar 22. The latter comprises two sections 23, 24 slidably mounted on the channel member and urged together by a spring 30. Each latch plate carries a card 160 controlling switch contacts 166, 168. The card 160 associated with switch C is rivetted to draw bar 24 at 218 for movement therewith. The interlock comprises interengaging pivoted members (200) positioned between the push buttons of switches A-F, Fig. 4 (not shown). Insertion of a coin energizes solenoid 50 moving the draw bar in direction 32 to free the latch plates. A collar on each push button A-F engages an aperture 144 in the corresponding latch plate to lock a push button in its depressed position. Pivotal movement of a latch plate closes switch contacts 166, 168 and moves draw bar section 24 to operate switch C. Control circuit. As described, push buttons A and B dispense beverages other than coffee and C-F coffee with or without cream and/or sugar. Insertion of a coin closes contacts 295, 297 momentarily to operate solenoid 265 closing hold-on contacts 266, contacts 267 in the circuit of solenoid 50 and contacts 268 in the circuit of motor 222. Switch C is closed automatically to complete the circuit of motor 222 driving a cam shaft one revolution to operate contacts 220 in a predetermined sequence. First, contact 328 closes to operate motors 260 and 262 of the cup dispensing unit. Next, the circuit for motor 250 will be completed through pairs of contacts 330, 334; 275, 276; 270, 272, provided neither of switches A and B have been operated, to dispense black coffee. Sugar and cream are dispensed by motors 254 and 256 when contacts 335 and 340 are operated unless one of the switches D-F have been depressed. Operation of a switch D-F will open the circuits of one or both motors 335 and 340. Extra cream and/or sugar is dispensed when the switches G and/or H are closed. Depression of switch A or B opens the circuits for motors 250, 254 and 256 to prevent the vending of coffee and so on and completes the circuits for motors 230 or 240 through contacts 350, 354 or 345, 347, respectively. Motor 234 drives a stirrer. If push button A is to dispense tea, contacts 300 and 304 are moved over whereby cream and/or sugar may be added by depressing push buttons G and/or H.

The auxiliary component described is a servosteering system 25. The pump 10 supplies fluid through a restrictor 17, the pressure drop across which is applied to a double acting piston 14 by lines 21 and 22, the piston adjusting the pump output, and through a pressure regulating valve 18 to the motor 11 (via line 16a), an output limiting valve 19 also being provided which can supply pressure fluid to a further pump adjusting piston 15 if the output pressure is high enough. The servo-steering system 25 is supplied through a flow regulating valve 27 having a piston 28 acted on by the pressure drop across a restrictor 26 the valve 27 also being controlled by the pressure in the valve output line 24 acting on a piston 29 to reduce flow when the steering is in the straight ahead position.

Abstract: 1,249,299. Welding by pressure. NATIONAL RESEARCH DEVELOPMENT CORP. 19 Feb., 1969 [5 Dec., 1967], No. 55241/67. Heading B3R. In bonding two metal bodies initially positioned apart with a cushion of gas at greater than atmospheric pressure between them, relative acceleration is produced between the bodies so that the gas is displaced and the bodies progressively collide with their surfaces at an angle to each other. The gas may be air or argon. A brass sheet 11, <SP>1</SP>/ 16  inch thick, is positioned above and at a small angle, up to 5 degrees, to a mild steel plate 10, 1<SP>1</SP>/ 8  inch thick, a rubber seal 12 extending around and stuck to the periphery of the plates to form a sealed space 13. A piece 14 forming part of a frame 16 and containing a gas connection 15 is secured to the plate 10 and on the upper surface of the sheet 11 is arranged a box 17 having a bottom 20 of rubber and transparent sides 31 containing explosive 18. In operation an explosive having a detonation velocity of 3900 metres per sec. is employed in the box, air at 30 p.s.i. is supplied to the space 13 to keep the sheet 11 from sagging and the explosive is detonated at one edge, e.g. opposite the gas connection 15. The area not bonded because of the seal 12 is trimmed. In a modification a rubber seal is stuck to the peripheral edge of the plate 10 and the sheet 11 is sealed to the rubber seal by adhesive tape and in this case the overlapping edges of the sheet are sheared off during bonding. The velocity of detonation of the explosive is preferably less than the sonic velocity of the plate 10 and the sonic velocity of the sheet 11 may be less than or greater than the detonation velocity. The sheet may be parallel to the plate, the explosive may be positioned in a non-uniform manner on the sheet, being thicker at the detonating edge, and explosive may be positioned on both the sheet and plate. Bearing alloys may be bonded to steel using nitroguanidine as explosive.
