An inflatable gate seal assembly includes a dump box that is mountable on a dump truck for carrying and dumping a load. A gate is hingedly coupled to the dump box for opening and closing the dump box. A conduit is integrated into the dump box and the conduit is fluidly coupled to an air compressor of the dump truck to receive compressed air from the air compressor. A control is positioned in a cab of the dump truck and the control is in electrical communication with the air compressor. A balloon is coupled to the dump box and the balloon is in fluid communication with the conduit. The balloon is inflated when the control is put in an on condition. Thus, the balloon engages the gate when the balloon is inflated and the gate is in the closed position to inhibit debris from passing between the dump box and the gate.

The present invention relates to a one-part, textile-reinforced molded hose (1) having at least one bend along its extension in a hose longitudinal direction (4a), in particular a sealing hose for sealing a screen with respect to a holding frame of a vibrating screen apparatus for separating solids from a mixture of liquid and solids, and to a method for producing the molded hose (1), a vibrating screen apparatus and a vehicle used in public transportation, each having such a sealing hose, and to the use of the molded hose as such a sealing hose.

A vehicle closure member sealing system includes a first seal including a first bulb section and an inflatable geometric feature disposed on a discrete portion of the first seal. The inflatable geometric feature includes a second bulb section separate from the first bulb section. A pressure source is configured to communicate a fluid into the second bulb section to inflate the inflatable geometric feature between a first position and a second position. The vehicle closure member sealing system may be utilized to seal a side door or liftgate.

An interface between two vehicle structures can be selectively sealed using an active seal. The active seal can include an outer casing and an actuator located within the outer casing. The actuator can include a bladder. The bladder can define a fluid chamber, which can contain a dielectric fluid. The actuator can include a first conductor and a second conductor operatively positioned on opposite portions of the bladder. The actuator can be activated and deactivated by selectively supplying electrical energy to the actuator. When electrical energy is supplied to the actuator, the actuator can have a reduced cross-sectional profile such that the interface is not sealed and movement of the second vehicle structure is not impeded by the seal. When electrical energy is not supplied to the actuator, the actuator can be in a non-activated condition in which the interface is substantially sealed.
