Title: Repair device

Abstract: 968,554. Plugging punctures. T. BEST. Dec. 18, 1961 [Jan. 10, 1961], No. 45198/61. Heading B7C. Punctured inflatable articles, such as tubeless tyres, are repaired by means of a flexible resilient plug 40 having a laterally extending flange 42 at its head end, the plug being inserted in the puncture hole by first loading it into a cylindrical chamber 31 of a fluid pressure operated ram gun, screwing a nozzle 15 to the front end of the chamber 31, inserting the nozzle into the puncture hole and then operating the gun to force the plug into a cylindrical bore 30 of the nozzle with its flange 42 folded forwardly until the flange 42 emerges inside the article and springs open to abut, on withdrawal of the nozzle, the inside surface of the article. As shown, the gun comprises a cylinder 26 secured at one end to a handle I and at the other to an adaptor 14 providing the chamber 31, the handle having a pressure fluid inlet passage 23, 24 leading to the cylinder 26 and controlled by a spring-loaded finger-operated valve 4. A spring-return piston 10, 11 operable in the cylinder 26 has a pistonrod 13 projecting into the chamber 31 of the adaptor 14 and terminating in a necked nipple 32 for engagement in a complementary undercut recess 44 in the tail end of the plug 40. The nozzle 15 has a tapered conical bore 29, where it adjoins the adaptor, leading into the cylindrical bore 30 of smaller diameter than the plug stem 43 and the adaptor chamber 31. In operation, the tail end of the plug is clamped in the conical bore 29 by the nipple 32, at the completion of the piston stroke, to limit the ejection of the plug through the nozzle. To facilitate insertion of the nozzle into the puncture, a moulded plastic taper-headed guide member may be inserted in the nozzle, the guide member remains in the tyre after the repair.

Title: Circuit for selection of alternative paths in telephone networks
IPC: H04Q3/00
Filed: 1961-12-18
Abstract: 1,003,140. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 18, 1961 [Dec. 17, 1960], No. 45296/61. Heading H4K. In a multi-exchange network such as that shown in Fig. 3 having provision for alternative routing, in order to avoid connections which have excessive attenuation or are otherwise unsuitable, the selection of routes at a tandem exchange is dependent on the route over which a call arrives as well as on the identity of the wanted exchange. Connections are set up under the control of a register at the originating exchange, Fig. 5 (not shown), which sends the designation of the wanted exchange in a 2 out of 5 voice-frequency code. At a tandem exchange, the identity of an incoming junction is determined by an identifier, Fig. 6 (not shown), and one of relays MR11 . . . 16 in a marker, Figs. 7-9, is energized in accordance with the incoming route. The incoming VF signal energizes two of relays R1 . . . 5, a check being made that the signal comprises two and only two frequencies, and these relays control three groups of relays R, P, Q, Fig. 9, which are arranged to mark a direct outgoing route, a first alternative route and a second alternative route. It is assumed that the marker shown is at exchange 12, and that a call originating at 241 and arriving via 24 is to be directed to exchange 34. Relay MR11 is energized from the identifier, and relays R3, R4 operated by the VF signal connect up R15 in series with MR8 to mark the junctions of the direct outgoing route to exchange 15. These are tested by relays VR1 . . . n, and if an idle junction is found the connection is made by apparatus K by the marking of the appropriate wires t3, t8. But if no idle junction is found, relay MR7 energizes and connects up P14 in series with MR6 (wires t6, t24 being connected together by MR11) to mark an alternative route via exchange 14. Relay MR3 operates to send back a signal of frequency f7 to the originating exchange, which now adds frequency f6 to the selecting signal to indicate indirect routing. If no idle junction is found in this route, MR4 pulls up and releases the marker, no second alternative route being provided in this case. If however the call is one which has already been indirectly routed, say from exchange 23 by way of 24, the frequency f6 included in the incoming VF signal operates relay R6 to prevent alternative routing at exchange 12. Instead of frequency f6 being sent forward, it may be arranged that if the register at the originating exchange receives the backward signal of frequency f7 a second time it releases the connection. On a call originating at 121, relay MR12 is energized, and in this case both first and second alternative routes are provided. On a call to be terminated at exchange 121, the selecting relays R1, R2 connect up relays R12, MR2, of which the former controls the selection of an outgoing line and the latter sends back a signal of frequency f8 to start the sending of the numerical digits.
