Abstract: An inflatable gas pipeline stopper is used for stopping gas flow through pipelines to permit repairs to be made to gas pipelines. For plastic gas pipelines, a tapping tee is attached to the plastic gas pipeline and a gas tight apparatus having a valve is attached to the tee. Thereafter, the plastic gas pipeline can be cut with a pipe cutter that is engaged with a hexagonal head and magnetic attachment to be operated from the exterior of the air tight apparatus. The pipe cutter can be removed from the air tight apparatus and the valve of the air tight apparatus closed to prevent gas from escaping from the pipeline. The inflatable gas pipeline stopper with dual air bags can then be inserted into the plastic gas main, through the air tight apparatus and the tee, to stop the flow of gas through the pipeline. After repairs on the pipeline are complete, the inflatable gas pipeline stopper can be removed, the tee can be stopped, and the air tight apparatus can be removed.

Abstract: These objects and advantages are achieved by the inflatable gas pipeline stopper of the present invention, which is used to stop gas flowing through a pipeline when effecting repairs of the pipeline. The invention includes an attachment for attachment to a gas pipeline. A quick connect is provided to form an airtight seal between the stopper and the attachment. A junction box is attached at the other end of the quick connect. The junction box has two receptacles on the upper end thereof for receiving two shafts therein. Each shaft has a port and a valve. At the top of each shaft is a quick connect for attachment of a stuffing box thereto for insertion of air lines therethrough. Within the two shafts, and attached to the air lines, extend two moveable bag inserting and retracting plunger assemblies attached to an air source at the tops thereof.

Abstract: An inflatable air mattress positioner is provided for use with a casket, coffin or alternative container. The assembly includes a partially pneumatic pillow with a chamber in which is disposed a plurality of air chambers, each one of which has a corresponding air tube and valve assembly in communication therewith. A cushion material is also included in the pillow. The cushion material coacts with the air bladders to position the head, upper arm, chest and shoulder region of a cadaver so that the cadaver chin is disposed in an acceptable proper height in relation with the chest according to that which is acceptable to the mortician and mourners. In addition, the assembly includes an inflatable air mattress having a plurality of air chambers which are independently inflatable to position a cadaver at an appropriate height and angle in the casket for mourner viewing.

Abstract: A pipeline flow stopper is insertable in a collapsed, deflated form in a pipeline through a tap hole and then inflated to temporarily block fluid or gas flow through the pipeline. The stopper comprises an inner inflatable bladder encased within an outer bladder casing. The inflatable bladder receives a pressurized gas and inflates to an inflated form within the pipeline. The bladder casing is constructed of fabric coated with a flexible polymer to render the fabric impervious to the fluid or gas in the pipeline. The fabric is joined together along seams either by stitching which is thereafter sealed by liquid seam sealer, cementing, vulcanization or the like, or the stitching can be eliminated entirely and all the seams electronically heat sealed to join them and prevent fluid or gas from escaping past the stopper through the seams.

Abstract: An inflatable gas pipeline stopper is provided for stopping gas from flowing through a broken gas pipeline while effecting repairs of the gas pipeline. The invention includes an elongated cylindrical stopper housing for attachment to a gas pipeline in an air tight engagement which may be accomplished through a commercially available drilling and tapping machine and by an air tight clamp assembly. Within the stopper housing extend a pair of moveable bag inserting and retracting plunger assemblies including rigid air pipes which are attached to an air source at the upper ends thereof and to inflatable air bags at the bottom ends thereof.

Abstract: The stopper includes a tubular cylindrical housing which seats on a gas main portion provided with a tap hole. A slidable tubular rod extends into the housing through the other end of the latter, and has connected to its lower end by a pivotal link, a stopper body in contracted condition for introduction into the gas main through the tap hole and being expansible within the main to stop the flow of gas therethrough. A packing gland assembly is provided on the other end of the cylindrical housing and is constructed to form a gas-tight closure for such housing, a gas tight slide guide for the tubular rod, and vent holes for the escape of gas from within the housing and into a venting pipe when the stopper additionally functions as a vent pipe. Normally however, the vent holes are closed by gas-tight plugs.
