Beanpots are typically made of ceramic, though pots made of other materials, like cast iron, can also be found. Billycan – a lightweight cooking pot in the form of a metal bucket [4] [5] [6] commonly used for boiling water, making tea or cooking over a campfire [7] or to carry water. [6]
Vacuum dryers are sometimes made up of cast iron, but most are made of stainless steel, so that they can bear the high vacuum pressure without any kind of deformation. The oven is divided into hollow trays which increases the surface area for heat conduction. The oven door is locked air tight and is connected to vacuum pump to reduce the pressure.
A tea draining tray, tea tray, Gongfu tea tray, or tea sea is an integral piece of equipment for the Gongfu tea ceremony.. It is essentially a grate, which allows excess and waste liquids to be drained away, and either collected in a pan under the grate, or drained away through a hose that carries the waste water and tea to a bucket or other drain.
1910 – "The Black & Decker Manufacturing Company" was founded by S. Duncan Black (1883–1951) and Alonzo G. Decker (1884–1956) as a small machine shop in Baltimore in September. Decker, who had only a seventh grade education, had met Black in 1906, when they were both 23-year-old workers at the Rowland Telegraph Company.
A theoretical plate in many separation processes is a hypothetical zone or stage in which two phases, such as the liquid and vapor phases of a substance, establish an equilibrium with each other. Such equilibrium stages may also be referred to as an equilibrium stage, ideal stage, or a theoretical tray. The performance of many separation ...
Schematics of a plate column with bubble cap trays. The feed to the column can be liquid, gas or gas and liquid at equilibrium. Inside the column there are always two phases: one gas phase and one liquid phase. The liquid phase flows downward through the column via gravity, [1] while the gas phase flows upward.
Black & Decker had trouble keeping up with demand for the Workmate in the UK, but was still unconvinced of how well the Workmate would be accepted in the United States. As a test of demand, the UK-manufactured Workmate WM325 was introduced to the United States market in 1974 as the Model 79-001 Type E ("E" for England).
A plate and frame filter press is the most fundamental design, and may be referred to as a "membrane plate filter." This type of filter press consists of many alternating plates and frames assembled with the supports of a pair of rails, with filter membranes inserted between each plate-frame pair. [citation needed]
