Abstract

The invention relates to a remote-controlled opening mechanism of an agent container of a supply capsule with an externally actuated signal transmitter which activates a circuit located in the capsule and heats a heating wire arranged in the circuit. In order to reduce the number of individual elements, to make the structure simpler and cheaper, and to better guarantee proper function, the heating wire is arranged in the immediate vicinity of the agent container.

Description

the rubber membrane (5) and the power of the energy source (8) about 2 seconds) closed so that the on the rubber membrane (85) adjacent heating wire (2) an opening or explosion of the rubber membrane in a matter of seconds (5) causes The switching time can be kept constant by appropriate presetting so that 100% functional reliability is guaranteed and Operating errors can be avoided.

The opening mechanism of the embodiment according to FIG. 3 consists of a current or circuit, be ίο standing on a source of energy coming from a voice coil (9), a capacitor (10) and a heating wire (2) The circuit runs through brief Energy supply from the outside through a high frequency generator, with the help of a transmitter with a corresponding Antenna for glowing the heating wire (2), so that the membrane directly on the heating wire (2) (5) is damaged (melted) and the active ingredient escapes in seconds as the rubber membrane is removed (5) is under pressure

Claims (5)

1 2 US Pat. No. 2,389,288 characterizes a remote patent claim: controlled detonators for rockets from flying bombs attached to a combat aircraft. 1. Transport capsule for pipeline systems with while the remote control of opening pre-electromagnetic through the pipe wall or the transport of capsules in principle are known by externally controlled capsule opening meter, can, however, by the US patent mechanism, characterized 36 18 874 and 23 89 288 does not do the following task to solve. a) that in a manner known per se in the capsule The invention is based on the object of a transein Active ingredient container is arranged, whose io port means to create relatively little construction effort. Wall is at least locally destructible, this in a system that has pipelines without in the case of destruction by an immediate structural change to the plant, relatively minor Close to the active ingredient container arranged amounts of active ingredients, such as. B. Dopants, Ka-Hehwire is initiated by an in catalysts or other active ingredients, at any point remotely controlled electricity in the capsule - 15 in the system with the medium in the system, circle can be activated; triggered by remote control, able to admit. b) that the capsule consists of two separable halves. The invention achieved this object by im stands, of which a half of the electrical characteristics of claim I contained Merk-part contains while the other half a times. Has an opening and the active substance that can be used for the 20 Because the length of the capsule is about 15 mm, the single use of the active substance is about 5-6 mm in diameter, is the transport encloses, its as a rubber-elastic meme of media within the narrowest system environments Bran trained wall possible under internal pressure. Another advantage is that the stands capsule shell after the transport process of the medium 25 does not have to be salvaged. The manufacturing costs are 2.
