String shopping bag Oranges packed in net bags. A string bag, net bag, or mesh bag is an open netted bag. Mesh bags are constructed from strands, yarns, or non-woven synthetic material into a net-like structure. String bags are used as reusable shopping bags [1] and as packaging for produce. [2]
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be emptied.
Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles.
External vacuum sealers involve a bag being attached to the vacuum-sealing machine externally. The machine will remove the air and seal the bag, which is all done outside the machine. A heat sealer is often used to seal the pack. Typically these units use a dry piston vacuum pump which is often considered a "maintenance-free" pump.
Diagram of a vacuum flask Gustav Robert Paalen, Double Walled Vessel. Patent 27 June 1908, published 13 July 1909. The vacuum flask was designed and invented by Scottish scientist James Dewar in 1892 as a result of his research in the field of cryogenics and is sometimes called a Dewar flask in his honour.
Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).
The straw bands can be vertical or horizontal; the former was traditionally used for fiaschi destined to local markets, while the latter, with a reinforced base and more careful weaving, was chiefly used for export. The latter often used a basket of whitened straw, decorated with two stripes tinted in the Italian flag colors (red and green).
Use of LifeStraw. The original LifeStraw is a plastic tube 22 centimetres (8 + 5 ⁄ 8 in) long and 3 centimetres (1 + 1 ⁄ 8 in) in diameter. [8] Water that is drawn up through the straw first passes through hollow fibres that filter water particles down to 0.2 µm across, using only physical filtration methods and no chemicals.
