Abstract: A rubber tired railway plow (100) has a plow unit (102) mounted to a plate (111) which extends across the forward end of the rubber tired vehicle (100). The plow unit (102) is attached so as to be movable on the plate (111). Wedges (122, 123) are used to maintain the plow unit (102) in position on the plate (111). When the wedges (122, 123) are removed, the plow unit (102) is movable on the plate (111) from one side of the vehicle (100) to the opposite side thereby to be able to plow on either side of the rails (141).

Abstract: A snowblower apparatus and a method of using the snowblower. The snowblower apparatus is self contained and portable and may be mounted on a prime mover. A turbine engine is located within a housing and discharges its exhaust to the desired area of snow or ice removal. The housing is rotatable and tiltable about orthogonal axes so as to allow the operator to direct the discharge nozzle to a desired location. A fuel tank may be mounted separately from the housing and turbine engine. An afterburner may be used to increase the exhaust temperature thereby to remove ice and otherwise dry the desired location.

Abstract: Pervaporation or vapor permeation apparatus and method having a separator module located in an unpressurized tank. The module has a plurality of stacked, disk-like separator elements mounted on a central, axial permeate removal tube. The separator elements have a central permeate transport plate, a pervaporation membrane enveloping the permeate transport plate and annular sealing rings located between adjacent membranes, so that fluid has to pass through the membranes to enter the permeate removal tube. A vacuum applied to the permeate removal tube draws permeate through the pervaporation membranes and permeate transport plates into the permeate removal tube. The permeate can be condensed right in the permeate removal tube by direct contact condensation using chilled liquid permeate, however an external condenser can be used. Jets of solution or bubbles of permeate vapor passing between the separator elements reduce or prevent concentration polarization.
