Abstract: 1,241,425. Capping bottles etc.; sealed containers; container closing apparatus. SIDAPLAX S.A. 15 Sept., 1969 [28 Oct., 1968], No. 61058/68. Headings B8C and B8T. Apparatus for closuring a container 3 consists of an electrically heated vertically movable frame 9 which has a lower chamfered part 10 and ribs 11. A pressure plate 12 which is heated by conduction from frame 9 forces the closure material 28 which is biaxially oriented resin, against the container edges pushing down the overlapping parts of sheet 28 and heating them at their contact point with ribs 11, alternate parts of the edge thus becoming cockled and being forced under the container lip. A cold crimping sleeve 16 moves upwardly, thus crimping the " pushed-down " portions of sheet 28 against the container lip, Fig. 3 (not shown). This position is maintained, during which the heat of the plate 12 causes shrinkage of the central top portion of sheet 28. The frame 9 and plate 12 are then moved away and the shrinking stresses in the central portion of sheet 28 pull the crimped edge portions into engagement with the container lip, forming a downwardly extending skirt which may be used in opening the container by use of a finger-nail. If there is no such skirt, a " tear-strip " may alternatively be substituted.

An extruded electrically conductive product 24 is pulled out of an extrusion press by inducing electromagnetic forces into the product. The latter is preferably of aluminium, aluminium alloy or copper. Upon emerging from the extrusion die 25, the product passes between carbon covered guides 26 into an air gap 4 provided between electromagnetic coils 2, 3. The upper coil 3 is mounted for vertical movement along guides 9, 10 by hydraulic or pneumatic cylinders 15, 16. After extrusion the discard is severed, coil 3 is moved downwardly to close the air gap 4 and the coils are energized by 3-phase alternating current to induce a longitudinal force into the produce and extract it from the die. The force may be varied by adjusting the voltage across the coils and a single force or a series of short duration forces may be used. A transverse force may also be applied to the product, by an hydraulic or pneumatic cylinder, by a vibrating pad or by induction coils, to facilitate its removal. The product passes on to a powered run-out table from which it is removed by lift-off arms. In other embodiments the electromagnetic device may be mounted on a carriage arranged to travel along the run-out table, or the longitudinal force may be produced by a pair of D.C. energized electromagnets which co-operate with a water spray to form a dielectric carrying a high current normal to the magnetic field. A longitudinal force may be applied continuously during extrusion to exert a pull on the product as it emerges from a water or air quenching station.

Abstract: 1495403 Detecting short circuits SOC ANON DES ATELIERS DE SECHERON 12 Dec 1974 [14 Dec 1973] 53764/75 Heading H2K To detect occurrence of a short circuit on a line AB carrying a direct current i, whenever signal u c  representing di/dt exceeds a threshold level u e  (at time t 1 , say) generation of two signals is initiated, the first u b  being equal to #u c  dt and thus representing the current i except for any initial level at time t 1 , the second u g  representing the accumulated sum of all the rising portions only of the waveform of u c . A short circuit is assumed to exist if u b  rises above u g , The detailed circuitry (Fig. 3d) includes an integrator 82 for evaluating u b , the integrator input being held at zero until a switch 81 is operated at time t 1 . The evaluator 84 for u g  comprises a feedback circuit having a first branch 841, 843, 847 responsive only to increases in u c  to store the accumulated value of these increases in 841, a second branch 842, 844, 848 similarly responsive only to decreases, and a summing amplifier 845 which sums the outputs of the two branches and feeds the sum back for balancing (846) with u c . Since when switches 843, 844 are operated at time t 1  to bring the circuit into operation u c  must already have attained the threshold level u e , an auxiliary feedback loop 849, 850 sets the initial value stored in 841 to u e  to minimize circuit response time. Switches 81, 843, 844 are changed back to disable the circuit if u c  should fall below a second, lower, threshold u a . The above system is particularly suitable for electric railway installations to detect short circuits which coincide with switching operations, and is preferably provided alongside other short circuit detecting systems all responding to u c =di/dt. In Fig. 2 four such systems are provided: a basic system 23 for detecting whether u c , having risen above the first threshold level u e , remains above the second level u a  for more than a predetermined time; a system 56 of the kind described in Specification 1,495,402 for overriding 23 if u c  exhibits the sequence rise-fall-rise, assumed to represent simultaneous starting of several motors; the system 8 of the present invention for preventing blocking by the system 56, thus preventing short circuits coinciding with switching operations from being confused with the starting of several motors; and an instantaneously-operating detector 10 with a very high threshold level.
