Abstract: A vehicle coolant system includes a pipe configured to facilitate a flow of vehicle coolant through the pipe, a light source configured to transmit at least one wavelength of light through the vehicle coolant, and a signal detector configured to receive at least one wavelength of light transmitted through the vehicle coolant, and to generate a signal intensity value corresponding to a measured intensity of the at least one wavelength of light received at the signal detector. A controller is configured to receive the signal intensity value from the signal detector, identify a coolant contamination threshold value corresponding to the vehicle coolant, compare the signal intensity value received from the signal detector to the coolant contamination threshold value, and initiate a vehicle coolant remedial action according to a result of comparing the signal intensity value received from the signal detector to the coolant contamination threshold value.

Abstract: A method for preparing a metallic surface of a device includes executing iterations of a first cleaning regimen and executing iterations of a second cleaning regimen. The first cleaning regimen includes applying a hydrocarbon solvent, e.g., an iso-octane solution, to the metallic surface of the device, executing a first sonication event on the device, and rinsing the metallic surface of the device. The second cleaning regimen includes applying a solution of chlorinated solvent to the metallic surface of the device, executing a second sonication event on the device, and rinsing the metallic surface of the device.

Abstract: A mobile vacuum distillation unit for extracting, condensing, and collecting volatile organic compound vapor emissions from one or more polymer-containing articles includes a shell that defines an enclosed interior space and is mounted to a transportable support platform, a vacuum distillation vessel, a condenser, a condensate storage tank, and a vacuum pump system in fluid communication with a vacuum distillation chamber of the vacuum distillation vessel. The vacuum distillation chamber that includes the one or more polymer-containing articles from which the VOC vapor emissions are extracted may be heated by an exhaust gas heat exchanger if the transportable support platform is connected to and hauled by a tractor unit powered by a diesel engine. A method of using the mobile vacuum distillation unit to extract VOC vapor emissions from one or more polymer-containing article during transportation of the one or more polymer-containing articles between geographically separate destinations is also disclosed.

Abstract: A welding assembly includes a sonotrode, cleaning station, and controller. The controller periodically commands clamping of the sonotrode onto the cleaning block, and a transmission of ultrasonic energy into the cleaning block for a calibrated duration sufficient for removing residual amounts of metal from welding pads of the sonotrode. The cleaning block may include an aluminum bar coated with a polymeric material, e.g., porous polyethylene silica or alumina composite. A thin sacrificial layer of an anti-adhesion material, e.g., colloidal silica, may be periodically applied to the welding pads, particularly after a transition from welding a first metal to welding a second metal. The sacrificial layer may be applied via a sponge, a saturated surface, or spraying.
Abstract translation: 焊接组件包括超声波发生器，清洁站和控制器。 控制器周期性地指示超声波发生器夹在清洁块上，并将超声波能量传输到清洁块中，该校准持续时间足以从超声波焊接焊盘去除剩余的金属量。 清洁块可以包括涂覆有聚合材料的铝棒，例如多孔聚乙烯二氧化硅或氧化铝复合材料。 特别是在从第一金属焊接到焊接第二金属的过渡之后，可以周期性地对焊接垫施加抗粘附材料（例如胶体二氧化硅）的薄牺牲层。 牺牲层可以经由海绵，饱和表面或喷涂施加。

Abstract: A heating, ventilation, and air conditioning (HVAC) system may comprise an evaporator core including an upstream inlet face in which humid air is received, a downstream outlet face from which dehumidified air is discharged, and a plurality of air-contacting surfaces extending between the inlet and outlet faces. In one form, an antimicrobial coating may be formed on the air-contacting surfaces of the evaporator core. The antimicrobial coating may comprise an ionic material having immobilized ionic groups of one type of charge and mobile counterions of another type of charge. The mobile counterions may be ionically associated with the immobilized ionic groups. In another form, an ultraviolet light emitting diode (UV-LED) may be used to direct UV light onto the air-contacting surfaces of the evaporator core.

Abstract: Volatile compound emissions from a product that comprises a polymeric material may be reduced or eliminated from the product by heating the product in a subatmospheric pressure environment. The product may be heated in the subatmospheric pressure environment at a temperature sufficient to vaporize a volatile compound contained within the polymeric material such that vapors of the volatile compound are extracted or released from the product.

Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.
