Abstract: Thermoplastic multi-walled pipe which has at least two tubular members different in inside diameter and concentrically arranged, these tubular members being spaced and supported by a plurality of ribs so as to provide hollow portions therebetween. The bond strength between the inner end surface of the rib and the tubular member supported thereby is less than that between the outer end surface of the rib and the tubular member supported thereby, so the exposure of the inner tubular member is easily achieved by means of an external force. After exposing the inner tubular member these multi-walled pipes are conveniently connected together by using a joint composed of a tubular part having the same inside diameter as the inner tubular member of the multi-walled pipe and a flange provided at one end of the tubular part concentrically therewith and having the same outside diameter as the multi-walled pipe, and in addition the hollow portion of the thermoplastic multi-walled pipe is kept sealed by the action of the flange.

Abstract: The stabilization of a fine dispersion of an immiscible liquid hydrocarbon fuel throughout an aqueous blasting composition having a continuous aqueous phase is accomplished by the use of a crystal habit modifier to reduce the crystal size of the oxidizer salt in the composition. Such reduction is found to be critical for stabilizing the fine dispersion of immiscible hydrocarbon fuel droplets throughout the composition and resultantly for maintaining the sensitivity of the composition to detonation.

Abstract: This invention relates to a flame monitor which has a sensing circuit 11 with a flame sensor 10 and a sensing relay 13 which switches a sensing switch 5 which is connected in parallel with a bridging switch 4 connected to a supply line 1. With one contact, sensing switch 5 controls a fuel valve 7 and with the other contact a circuit 16 with two alternatively energized relays, a bridging relay 24 and a relay 27 for switching the flame loss simulation and a timing device 30. The bridging switch 4 switches the fuel valve 7 and a safety circuit 3 with a safety relay 22 for switching a safety switch 2 located in the supply line and a parallel connected second timing device 31. During operation the first timing device 30 is discharged, causing the bridging switch 4 to provide parallel energization of the fuel valve 7 and then the flame loss simulation is actuated by relay 27 so that sensing switch 5 switches power to circuit 16 and timing device 30 is charged. Relay 13 then removes the flame loss simulation from the flame sensing circuit 11, so that sensing switch 5 again energizes fuel valve 7, while bridging switch 4 switches safety circuit 3. The cycle then starts again. <IMAGE>
