Abstract: A method for the suppression of coal seam fires provides for the location and determination of the boundaries of a coal seam fire, directing access to the coal seam, preparation of the coal seam prior to suppression and the suppression of the fire within the coal seam using a foam mixture, the method providing minimal impact and disruption to the surface above the coal seam fire.

Abstract: A method for forming a barrier to seal off a remote chamber includes the steps of: forming a borehole that communicates between a first location and the remote chamber; inserting a conduit through the borehole to extend into the remote chamber; introducing a flowable material through the conduit to the remote chamber and dispensing the flowable material from the conduit to the desired location for the barrier, the flowable material upon being dispensed producing a substantially solid, self-sustaining composition; maintaining dispensing the flowable material to produce a sufficient quantity of the self-sustaining composition to form the barrier to seal the remote chamber, while ensuring that the composition does not block the borehole from communicating between the first location and the remote chamber; and thereafter removing the conduit to allow access to the borehole.

Abstract: A reusable minimal use soap bar comprising a structural core surrounded by a soap layer composition existing in a solid phase. The soap bar can be single or multiple use, depending on the thickness of the soap layer around the core. After use the structural core is replenished with a fresh coating of soap. A method for stripping any existing soap layer and replenishing the core with a fresh coating of soap for reuse is disclosed.

Abstract: A method is provided for the accurate placement and replacement of EKG electrodes on a patient. In accordance with the invention, the method comprises marking the position of the EKG electrodes with a removable tattoo so that on a subsequent run the electrodes can be replaced at their original locations as marked. The method also allows an experienced operator to first mark the proper location so less experienced operators can correctly position the electrodes on a patient.

Abstract: The method of the invention comprises the steps of proportioning a foam concentrate into a non-flammable liquid to form a foam concentrate/liquid mixture and creating a flowing stream of the foam concentrate/liquid mixture. Nitrogen is introduced into the stream of the foam/liquid mixture to initiate the formation of a nitrogen expanded foam fire suppressant. In one embodiment the nitrogen is chilled below ambient temperature. The flowing stream carrying the initially nitrogen expanded foam is dispensed, which completes the full expansion of the nitrogen expanded foam fire suppressant, into the confined area involved in fire thereby to smother the fire and to substantially close off contact between combustible material involved in fire and the ambient atmosphere substantially reducing the danger of explosion or flash fires.
