In explosively bonding a metal cladding sheet to a metal base sheet the cladding sheet is provided with dimples forming integral projections and with the projections spacing the cladding sheet from the base sheet and with the two sheets held immovably together, a layer of explosive on the cladding sheet is ignited. Spaced projections 2, Fig. 1, are pressed into the cladding sheet 1 and these projections are ultrasonically or electric pressure welded at 6 to the base sheet 3, a layer 5 of oil, lacquer, oilimpregnated cardboard, plastics, self-adhesive plastics foil &c. is provided on the upper surface of the sheet 1 and a layer 4 of explosive is arranged on the protective layer 5. The recesses above the projections are filled with putty 9. The explosive layer is ignited at one edge to bond the cladding and base sheets. In modifications a weight, e.g. sand or water, or clamps, straps or vices may be used to hold the cladding sheet down instead of welding the projections. Bent leaf-springs 10, Fig. 5, are held in the chain line position on the cladding sheet by hooks 11 as another alternative, the explosive layer being applied over the springs. In another embodiment the cladding sheet is initially curved and is held tensioned against the base-plate by steel straps, clamps or vices.

Abstract: 610,043. Automatic exchange systems. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 3, 1945, No. 20055. Convention date, May 28, 1942. [Class 40 (iv)] In a system in which calls are set up over finder-connector links, several subscribers have a common line relay A which when energized over switch-hook contacts Cr1, Cr2 of a calling substation, starts a self-interrupting relay B, shunted by condenser C10, and impulses generated at b1 first home the connector CO and then step the finder Ch. Test relay 3 operates over the calling loop and connects relays 1, 2 in series, whereupon switching relay 5 energizes in series with the cut-off relay C and short-circuits its high resistance winding to mark the line busy. Relays 1, 2 hold over the loop and dialling tone is applied from vibrator VO. Dialled impulses are repeated by relay 1 to step the connector CO after which the calling subscriber presses button BP to short-circuit relay 2. If the called line is idle, switching relay 4 energizes in series with the cut-off relay, disconnects dialling tone and connects battery to the b wire to operate the called subscriber's buzzer R, ringing tone being fed back to the calling subscriber through condenser C3. If the called line is busy, relay 4 does not operate and dialling tone remains on the line as a busy signal.

Title: Electrical annunciator and alarm devices, particularly for burglar and fire alarms
IPC: G08B13/189
Filed: 1920-07-10
Abstract: 148,480. Schmidt, G., and B÷ker & Co. March 27, 1918, [Convention date]. Alarms, fire &c.-Relates to fire and other alarms operated by a selenium cell when illuminated or shaded contrarily to its normal state. In one method, illustrated in Fig. 1, equal selenium cells S<1>, S<2> adjusting resistances W<1>, W<2> and coils a, a<1> of a differential relay R are connected in two parallel circuits energized by the battery B<1>. When a shadow falls on one of the cells S<1>, S<2> in the day time, or a ray of light at night, the tongue Z of the relay R closes a circuit through the alarm bell F and battery B<3> over conductors 5 and 6, and a hold-on circuit over the conductor 7 ensures continued ringing of the bell. A lamp L can be brought into circuit by means of the switch A' for the purpose of adjusting the contacts K, K<1> which can be turned about pins k, k<1>. The cells S<1>, S<2> may be screened laterally and may be furnished with lenses. In the form shown in Fig. 2 the galvanometer R operates the alarm when the cells S, S<2> are differentially illuminated, as already described. In addition, however, a galvanometer G' is so arranged that during the day time current from the battery B<2> flows through it in series with the cells S, S<2> via the contacts m, n. At nightfall, however, the rise in resistance of the cells causes the needle to make contact at K<2> so as to energize a magnet, attract the armature x and trip the lever o. In consequence, the galvanometer G is cut out of circuit by the breaking of contact at m, n, and the galvanometer G<2> is put in circuit with battery B<2> and cells S, S<2> in series by the making of contact at o &c. Thereafter any general illumination of the cells S, S<2> causes a rise of current through the galvanometer G<2> which thereupon operates the alarm, while a differential illumination of the cells S, S<2> will also cause the galvanometer R to operate the alarm as before. According to the Specification as open to inspection under Sect. 91, the galvanometer R with its associated circuits may be omitted. The galvanometers G<1>, G<2> with their circuits then form an alarm apparatus, which is inactive during the day time but automatically becomes effective after nightfall.
