Abstract: The present invention relates to an adjustable bulkhead for preventing the movement of lading within a lading carrying vehicle, such as a railway car, and more particularly, relates to a mechanical bulkhead having a structural frame member adapted to be mounted in a stationary position, with one or more expandable panels connected to said frame member by clevis linkages which are operated by one or more hydraulic cylinders. By the use of an air-operated hydraulic pump fed by a constant volume air reservoir of a size chosen so that as the bulkhead expands the pressure of the air supplied to the hydraulic pump, and thus, the oil pressure in the hydraulic cylinder, will decrease as the natural mechanical advantage of the clevis type linkage comes into play, a substantially uniform force can be kept on the lading regardless of the amount of the expansion of the bulkhead.

Abstract: The specification discloses a novel energy saving forced-air furnace. In contrast to previous forced-air furnaces, which ran only on gas or oil and in which approximately half of the energy derived from the burning fuel was lost through the chimney, the furnace of the present invention can run on coal, wood, gas or oil and retains a substantial portion of the heat which normally would be lost by the utilization of special tubing units and refractory plates. My furnace saves the greatest amount of energy possible by providing a heat chamber having a special tubing unit therein from the surface area of which heat generated in a stove chamber is transferred to a heat chamber and simultaneously through which exhaust gases air conducted from the stove chamber mounted below the heat chamber to the exterior of the furnace. Refractory plates are placed in a serial arrangement within the furnace heat chamber with spaces provided between them.

Abstract: The specification discloses a novel composite coalescing filter tube and the method of making the same. In contrast to previous coalescing filters, which had layers of filter material sandwiched between relatively rigid support members, the present invention provides for a completely unitary coalescing filter tube wherein the various layers of the filter are successively vacuum formed one over the other on a forming fixture which is submerged in an appropriate glass fiber slurry mix, with the various layers being air dried, epoxy dipped, and cured as needed for the particular application. Since, during the vacuum forming process, glass fibers from one layer will interlock with glass fibers from the previously formed layer, a completely unitary coalescing filter tube is formed, preventing the problems of filter layer separation, channeling, pressure collapse and vibration damage which have occurred in past coalescing filters.
