Abstract: A tubing cutter apparatus includes a housing or casing member formed of a zirconia ceramic material. The zirconia ceramic material is located at least proximate an explosive charge section, such the detonation of the explosive charge will cause shattering the ceramic section. The tubing cutter may be assembled in a safe manner by establishing ground connections between separate portions of the apparatus. These ground connections established during assembly will prevent the buildup of static electrical charges, which could cause premature detonation of the cutter.

Abstract: A timing circuit includes a variable frequency oscillator which has a control signal that determines the output frequency of the oscillator. The control signal and a reference signal are stored in the circuit. A precision calibration pulse is applied to the timing circuit which counts the output cycles of the variable frequency oscillator during the period of the pulse. This count is stored and compared to the reference count to produce an error count. This error count is combined with the previously stored control signal to produce a new control signal that drives the output of the oscillator to a new frequency. The timing circuit can be utilized as a part of a delay circuit is an electronic blasting system wherein a control unit transmits the calibration pulse concurrently to each of the delay circuits to cause each circuit to calibrate its local oscillator in accordance with the calibration pulse. The control unit transmits a delay count to each of the delay ignition circuits.

Abstract: A metal structure component is provided with a protective coating including three layers. A first layer on the surface of the metal structural component is a bond improving metallic base layer on which an intermediate heat insulating oxidic layer is applied, followed by a titanium fire inhibiting metallic cover layer. Due to this arrangement of three layers, it is possible for the advantageous characteristics of the individual layers to cooperate to provide a good bonding and heat insulating protection of the intermediate layer in combination with the titanium fire inhibiting protection of the outer layer, whereby the structural component achieves a prolonged operational life without a substantial weight increase as compared to conventional protection layers provided only for heat insulation purposes. This layer structure also minimizes any adverse influence on the structural strength of the metal structural component.
