The self-sealing suction cup is a suction cup that exerts a suction force only when it is in physical contact with an object. Unlike most other suction cups, it does not exert any suction force when it is not in contact with an object. [1] Its grasping ability is achieved entirely through passive means without the use of sensors, valves, or ...
There are several densities for lead glass, but the most common is 5.2 g/cm 3. A rough calculation for lead equivalence would be to multiply the required Pb thickness by 2.5 (e.g. 10 mm Pb would require a 25 mm thick lead glass window). Older hot cells used a ZnBr 2 solution in a glass tank to shield against high-energy gamma rays. This ...
Scientific glass blowing, which is practiced in some larger laboratories, is a specialized field of glassblowing. Scientific glassblowing involves precisely controlling the shape and dimension of glass, repairing expensive or difficult-to-replace glassware, and fusing together various glass parts.
In robotics, a manipulator is a device used to manipulate materials without direct physical contact by the operator. The applications were originally for dealing with radioactive or biohazardous materials, using robotic arms , or they were used in inaccessible places.

The gas in a glovebox is pumped through a series of treatment devices which remove solvents, water and oxygen from the gas. Copper metal (or some other finely divided metal) is commonly used to remove oxygen, this oxygen removing column is normally regenerated by passing a hydrogen/nitrogen mixture through it while it is heated: the water formed is passed out of the box with the excess ...
Manipulators act as “muscle multipliers” by counterbalancing the weight of a load so that an operator lifts only a small portion (1%) of the load's weight, and they fill the gap between hoists and industrial robots: they can be used for a wider range of positioning tasks than hoists and are more flexible than industrial robots due to their ...
A classic 20-facet Soviet table-glass, produced in the city of Gus-Khrustalny since 1943. Tumblers are flat-bottomed drinking glasses. Collins glass, for a tall mixed drink. [5] Dizzy cocktail glass, a glass with a wide, shallow bowl, comparable to a normal cocktail glass but without the stem; Faceted glass or granyonyi stakan
