Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.
The spores of rust fungi may be dispersed by wind, water or insect vectors. [13] When a spore encounters a susceptible plant, it can germinate and infect plant tissues. A rust spore typically germinates on a plant surface, growing a short hypha called a germ tube. This germ tube may locate a stoma by a touch responsive process known as ...
For stain removal, conventional household washing machines use heated water, as this increases the solubility of stains. However, heating the water to the required temperature uses a considerable amount of energy; energy usage can be reduced by using detergent enzymes which perform well in cold water, allowing low-temperature washes and ...
Soybean rust is a disease that affects soybeans and other legumes. It is caused by two types of fungi, Phakopsora pachyrhizi, commonly known as Asian soybean rust, and Phakopsora meibomiae, commonly known as New World soybean rust. P. meibomiae is the weaker pathogen of the two and generally does not cause widespread problems.
Its treatment and disposal is an important environmental consideration for coffee processing as wastewater is a form of industrial water pollution. [ 1 ] The unpicked fruit of the coffee tree, known as the coffee cherry, undergoes a long process to make it ready for consumption .
Some laundry wastewater goes directly into the environment, due to the flaws of water infrastructure. The majority goes to sewage treatment plants before flowing into the environment. Some chemicals remain in the water after treatment, which may contaminate the water system. Some have argued they can be toxic to wildlife, or can lead to ...
Gradually, the electric washing machine's spin cycle rendered this use of a mangle obsolete, and with it the need to wring out water from clothes mechanically. Box mangles were large and primarily intended for pressing laundry smooth; they were used by wealthy households, large commercial laundries, and self-employed "mangle women".
An archaic form of this washer was sold as a "pot mender", usually in small quantities through a retail ironmonger. This included two washers, a nut, and bolt, and a sealing washer of rubber, cork, or fibre sheet. They could be used for sealing small holes, rust spots or removed pipe connections in water tanks or large cooking vessels.
