Abstract

An explosion-driven setting tool includes a setting mechanism (12) driven by a propellant (23), an ignition unit (18) for igniting the propellant (23), a receptacle (15) for receiving a propellant holder (20), a data communication interface (31) for receiving and transmitting data of the propellant holder (20), and a data processing unit (30) for receiving data transmitted by the data communication interface (31) and connected with a display (50) for displaying the propellant supply level (27) of the propellant (23) in the propellant holder having a housing (21) with an interior space (22) for receiving the propellant (23), and a data storage identification unit (40) in which the propellant supply level (27) is stored for being read-out.

Claims

1. A propellant holder for being releasably mounted in a setting tool having a receptacle (15) for receiving the propellant holder (20) and a data communication interface (31) provided in a predetermined region of the receptacle (15), the propellant holder comprising:

a housing (21) having an interior space (22) for receiving propellant (23);

a data storage identification unit (40) affixed to the housing (21) and in which an actual propellant supply level (27) is stored to be read-out by the data communication interface (31); and

guide means (26) cooperating with respective guide means (126) provided in the predetermined region of the receptacle (15) to enable the data communication interface (31) to read-out the propellant supply level (27) stored in the data storage identification unit (40);

wherein the guide means (126) secures the propellant holder (20) in a predetermined position.

2. The propellant holder of claim 1, wherein the guide means (26) cooperates with the respective guide means (126) provided in the predetermined region of the receptacle (15) for securing the propellant holder (20) in the predetermined position in the predetermined region of the receptacle (15) to enable the data communication interface (31) to read-out the propellant supply level (27) stored in the data storage identification unit (40).

3. An explosion-driven setting tool, comprising:

a setting mechanism (12) driven by a propellant (23);

ignition means (18) for igniting the propellant (23);

a receptacle (15) for receiving a propellant holder (20);

a display (50) for displaying a propellant supply level (27) in the propellant holder (20);

a data communication interface (31) for receiving data from and transmitting data to a data storage identification unit (40) and located in a predetermined region of the receptacle (15), the receptacle (15) having guide means (126) cooperating with guide means (26) of the propellant holder to enable the data communication interface (31) to read-out the propellant supply level (27) stored in the data storage identification unit (40) of the propellant holder (20); and

a data processing unit (30) operationally connected with the data communication interface (31) and the display (50);

wherein the guide means (126) secures the propellant holder (20) in a predetermined position.

4. An explosion-driven setting tool, comprising:

a setting mechanism (12) driven by a propellant (23);

ignition means (18) for igniting the propellant (23);

a receptacle (15) for receiving a propellant holder (20), with the propellant holder (2) having a housing (21) with an interior space (22) for receiving propellant (23), and a data storage identification unit (40) in which a propellant supply level (27) is stored for being read-out;

a display (50) for displaying the propellant supply level (27);

a data communication interface (31) for receiving identification data read-out from the data storage identification unit (40) and provided in a predetermined region of the receptacle (15), the receptacle (15) having guide means (126) cooperating with guide means (26) of the propellant holder to enable the data communication interface (31) to read-out the propellant supply level (27) stored in the data storage identification unit (40); and

a data processing unit (30) for receiving the identification data from the data communication interface (31) and connected with the display (50) for communicating the propellant supply level (27) thereto;

wherein the guide means (126) secures the propellant holder (20) in a predetermined position.
