This type of seal will normally have buffering via a single ported labyrinth located inboard of the seal and a positive shutdown device, which will attempt to maintain gas pressure in the casing when the compressor is at rest and seal oil is not being applied. For shutdown, the carbon ...
Sealing procedure for sealing a water well made of concrete rings against surface water running down. The procedure comprises an inner casing produced, by various means, of a plastic suitable for foodstuffs, so that surface water is prevented from running down through the concrete-ring joints into...

At the bottom of the casing, a slotted screen is attached to strain silt and sand out of the groundwater. A submersible pump driven by an electric motor can be used to raise the water to the surface. Sometimes a deep well may penetrate a confined artesian aquifer, in which case natural...
It is well known that water molecules sonolyzed to hydrogen radicals (H•) and hydroxyl radicals (•OH) during ultrasonic process. Hence, hydroxylation of terephthalate can be possibly promoted by •OH radical, forming functional groups on polyester surface improving the wettability (Harifi ...
pullout resistance because of the increased surface area and roughness. The presence of grout may also provide increased corrosion protection. However, the construction process may also cause disturbance to the ground, and casing is required in some soil conditions to prevent hole collapse during ...
Fifthly, the diaphragm method is amenable to a variety of combustible gases -coal or coke oven gas (either undiluted or admixed with water gas), natural gas, petrol-air gas, car- buretted water gas are all well suited in cases where unimpeded radiation is required. Finally, the incan- ...
