An adhesive dispensing system is disclosed. The system includes a heater unit configured to heat an adhesive to an application temperature, a fill system configured to supply the adhesive to said heater unit, and a controller. The controller is configured to actuate the fill system to supply the adhesive to the heater unit, operate the heater unit to maintain a unit set point temperature sufficient to heat the adhesive to the application temperature, and operate the heater unit to reduce its temperature from the unit set point temperature following a first set threshold time from actuation of the fill system to supply the adhesive to the heater unit.

Various embodiments of a heat-exchange dryer apparatus are disclosed. In one embodiment, a heat-exchange dryer apparatus includes a desiccant cartridge comprising desiccant material, a purge-air reservoir secured to the desiccant cartridge, and a compressed-air conduit disposed inside the purge-air reservoir. In another embodiment, a vehicle air-brake system includes an air compressor, a desiccant cartridge comprising desiccant material, and a heat exchange dryer apparatus disposed between the compressor and the desiccant. The temperature of the compressed air is decreased while the temperature of the purge air is increased and the desiccant adsorbs a greater amount of contaminants form the compressed air for improved drying.

A method is disclosed herein for detecting cracks of a fluid storage tank due to breakage of a wall of the fluid storage tank. In an example embodiment, the method includes positioning an enclosed pressure-resistant jacket around an outer wall of the fluid storage tank, controlling a temperature of the fluid in the fluid storage tank by allowing a liquid cooling or heating medium to flow in the enclosed pressure-resistant jacket at a pressure lower than a pressure x applied within the fluid storage tank, maintaining the pressure in the pressure-resistant jacket lower than the pressure x, sampling the cooling or heating medium from an air pool provided in a passage of the cooling or heating medium, and analyzing components of the cooling or heating medium, while preventing contamination of the fluid in the fluid storage tank with the liquid cooling or heating medium.

An underwater assembly includes a flow control device and an actuator coupled to the flow control device, where the actuator is configured to actuate the flow control device. The underwater assembly further includes an insulated housing surrounding the flow control device and the actuator, where the insulated housing is configured to retain heat. The underwater assembly also includes a thermal control system comprising a heat exchanger configured to control a temperature of the actuator.

Automated fluid handling system comprising a housing (20) and two or more fluid handling units (26) arranged as interchangeable modular components with an external fluidics section (30) and an internal non fluidics section (32), and wherein the housing (20) comprises a liquid handling panel (22) with two or more of component positions for receiving said interchangeable modular components (26) such that the external fluidics section (30) is separated from the non fluidics section (32) by the liquid handling panel (22).

Embodiments of the present invention provide a water management system for use on board a passenger transport vehicle. The water management system may be used to address and manage excess humidity, water leaks, or any other instance when water or other liquid may collect at a certain location. The disclosure provides a system for managing excess water and for optionally delivering the water to another location. The removal location may be a disposal outlet or it may be a beneficial use of the collected water on-board the vehicle.

The invention relates to a device for metering fluid, particularly for the metered injecting of a reduction agent into the exhaust tract of an internal combustion engine, which has an electrically controllable metering valve (11) having a valve housing (16), having an inlet opening and a metering opening (14, 15) for the fluid, and a cooling module (12) to which a coolant is applied for cooling the metering valve. In order to achieve a permanent fording ability of the device, the metering valve (11) is hermetically sealed in the cooling module (12) and only the inlet opening and the metering opening (14, 15) of the valve housing (13) are exposed.

An apparatus capable of heating a liquid may provide a valve assembly configured to receive an incoming liquid from a bulk source. The valve assembly may control the flow of the liquid to a source vessel via a pipe system. The pipe system includes a first pipe directly connected to the valve assembly and a second pipe downstream from the first pipe and connected between the first pipe and the source valve. The second pipe is heated with a heating system that surrounds the second pipe, and the second pipe has a larger diameter than that of the first pipe.

Methods for managing a hazardous fluid within a pipeline and within a storage facility, and in particular for managing a potential or actual leak of the hazardous fluid. Such methods include the detection of such an event by one or more sensors, and the containment and the mitigation of the event.

A method is disclosed herein for preventing contamination of a fluid in a fluid storage tank with a liquid cooling or heating medium due to breakage of a wall of the fluid storage tank. In an example embodiment, the method includes positioning an enclosed pressure-resistant jacket around an outer wall of the fluid storage tank, controlling a temperature of the fluid in the fluid storage tank by allowing the liquid cooling or heating medium to flow in the enclosed pressure-resistant jacket at a pressure lower than a pressure x (atm) applied within the fluid storage tank, and maintaining the pressure in the pressure-resistant jacket lower than the pressure x.
