Patent GB-1456530-A (GB)
Title: Apparatus for embossing sheet metal strip
IPC: B21D13/02
Filed: 1973-12-07
Abstract: 1456530 Corrugating; shearing; making sheet metal panels B & K MACHINERY INTERNATIONAL Ltd 7 Dec 1973 [7 Dec 1972] 56763/73 Headings B3E B3A and B3W A sheet metal panel cut to length from strip comprises a central portion 11 and two side portions 12, Fig. 1, the latter having continuous roll formed longitudinal formations extending from one end to the other, and the central portion having a plurality of identical transverse corrugations 13 terminating just short of the longitudinal folds, and flat end portions 14. The panel edges may have interengageable formations for assembly of the panels, and the transverse corrugations may be interrupted by a central longitudinal folded formation (Fig. 4, not shown). The first station of a production line is shown in Fig. 6, where incoming strip S is fed over braked bridle rolls 20, 21 with snubbing rolls 23, and through cold working rolls 29, 30 backed up by rolls 25, 27, the lower rolls being disengageable as required by jack 32 and adjustable in height by jack 36. The lower work roll 30 is of a length equal to the width of the central portion of the strip, so that the side portions do not get worked to the same extent. The strip then passes to transversely corrugating rolls 38, 39, the latter engageable by jack 40, where the central portion is transversely corrugated as required, and thence to rolls 44, 45 which apply tension to the corrugated strip against the back tension of the bridle rolls. Thereafter, the strip is longitudinally formed along its side portions, and cut to length by a flying shear (not shown). Passage of the strip is recorded by a measuring device and counter, which intermittently disengages the cold working, transversely corrugating, and tension applying rolls, whereby the required flat regions are left in the central portion of the strip, and a datum hole is punched in the strip. Downstream of the longitudinal forming rolls, a hole detector ensures that operation of the flying shear divides the strip in the flat central regions. The speed of the motors driving the various rolls and the shear are monitored and co-ordinated. Fig. 11 shows an alternative transverse corrugating device, in which die elements 82 are attached to endless belts 80, 81 running over convergent guides 85, 86, while the strip edges are held flat by rolls 78, 79. One belt guide roll 73 is adjustable by block 74 and by cam 75. Adjacent die elements are linked together to reduce forces on the belts. Fig. 13 shows another alternative, in which a corrugating roll 99 cooperates with die elements 91 on belt 90 passing over a needle roller bed 100.

Abstract: 1280669 Road traffic signals; alarm systems UNITED-CARR Inc 12 Dec 1969 [26 Dec 1968] 60694/69 Headings G4N and G4Q A flasher-buzzer device for an automobile comprises a relay adapted to serve the dual functions of a flasher unit and a buzzer or inadvertence (e.g. ignition circuit on, headlights on) signal unit. The relay 10 has a core 11 with windings 12, 12a which when energized close normally open contacts 13, 14, the armature contact 14 being normally closed with contact 15. In flasher circuit operation, closure of turn signal switch 18 with either of turn lamp circuits 16, 17 energizes winding 12a closing contacts 13, 14, completing the lamp circuit for a period determined by the time constant of the winding 12a and a condenser 20 connected in parallel with this winding. A voltage dividing resistor 22 between the condenser 20 and the positive terminal 24 is preferably of the same resistance as the winding 12a. In buzzer circuit operation, normally closed contacts 14, 15 connect winding 12 from positive terminal 24 through a normally open control switch 25 to ground. The switch 25 may be actuated by conditions such as an open door, a key in the ignition in the ON position, or like circumstances of operator inadvertence. Closure of switch 25 energizes winding 12 effecting opening of contacts 14, 15 thereby de-energizing winding 12 and releasing armature contact 14 which re-engages contact 15, thus setting up an oscillatory buzzing action which will continue until the switch 25 is opened. Several separate buzzer control switches connecting to terminal 26 of relay winding 12 may serve several separate warning requirements. A pilot lamp 27 may be connected in each separate buzzer warning circuit having its own control switch 25, but a single buzzer device only is employed.
