An aerated wax application assembly comprises a meltable wax applicator, one or more meltable wax delivery conduits having a first end coupled to the meltable wax inlet of the meltable wax applicator and a second end positioned proximate a meltable wax holding tank, and an air injection system positioned upstream from the meltable wax applicator and configured to inject air into the meltable wax and generate the aerated meltable wax upstream of the inlet of the meltable wax applicator. A method of applying an aerated meltable wax onto an object comprises injecting air into a meltable wax such that it forms an aerated meltable wax, delivering the aerated wax through one or more meltable wax delivery conduits to a meltable wax applicator, and contacting at least one exposed surface of the object with the aerated wax when dispensing the aerated meltable wax from an outlet of the meltable wax applicator.

In a method for applying a substance to a moving web (4) of a product, an air-vapor mixture is supplied to at least one nozzle (13) in which the substance is propelled by means of the air-vapor mixture as propellant in an application zone (32) on the web (4) is applied. Excess air-vapor mixture and excess material are removed from the application zone (32). In order to improve the energy efficiency of such a process, it is proposed that at least part of the excess air-steam mixture discharged from the application zone (32) be recycled and returned to at least one nozzle (13). In addition, a device (1) for carrying out the method described above is proposed.

A method for producing films or more precisely stated, mats and plates out of nanofibers, in particular films or mats and plates out of cellulose nanofibers, wherein nanofiber material is dispersed in solvent; the solids content is between 1 and 4% by volume and the resulting slurry is applied by means of an application device to a conveyor belt that is moving in the conveying direction and then the poured-on slurry is pre-dried and the pre-dried slurry, after the pre-drying, is subjected to the main drying and after the achievement of a predetermined moisture content, is removed from the conveyor belt.

A heat-pump circuit may include an indoor heat exchanger, an outdoor heat exchanger, a compressor adapted to circulate a working fluid between the indoor and outdoor heat exchangers, and an expansion device disposed between the indoor and outdoor heat exchangers. A monitor for the heat-pump system may include a return-air temperature sensor, a supply-air temperature sensor, and a processor. The return-air temperature sensor may be adapted to measure a first air temperature of air upstream of the indoor heat exchanger. The supply-air temperature sensor may be adapted to measure a second air temperature of air downstream of the indoor heat exchanger. The processor may be in communication with the return-air temperature sensor and the supply-air temperature sensor. The processor may be programmed to determine a working-fluid-charge condition of the heat-pump system based on the first and second air temperatures.
