Siping is a process of cutting thin slits across a rubber surface to improve traction in wet or icy conditions. Siping was invented and patented in 1923 under the name of John F. Sipe . [ 1 ] [ 2 ] The story told on various websites is that, in the 1920s, Sipe worked in a slaughterhouse and grew tired of slipping on the wet floors.
Groundwater sapping is a geomorphic erosion process that results in the headward migration of channels in response to near constant fluid discharge at a fixed point. The consistent flow of water displaces fine sediments which physically and chemically weathers rocks. [1]

Water seal under a sink. Inverted siphoning occurs below the line "A". An inverted siphon is not a siphon but a term applied to pipes that must dip below an obstruction to form a U-shaped flow path. Large inverted siphons are used to convey water being carried in canals or flumes across valleys, for irrigation or gold mining.
The first commercial use of siping was a year earlier, where Tecalemit used a knife-cutting process almost identical to Sipe's original patent as a means of recutting worn treads. Europe also abandoned the slow process of literally knife cutting in favour of steel blades in the tread moulds, forming the sipes by moulding.
This is a heavy duty rubber hose that is inserted at the end of the flow line and at the other end emplaced into the sample box itself. The sample box is used to capture samples of drill cuttings for geological logging. The box is typically equipped with a raising door that allows the water and cuttings to escape after a sample is collected.
Curing is the process of applying pressure to the green tire in a mold in order to give it its final shape and applying heat energy to stimulate the chemical reaction between the rubber and other materials. In this process the green tire is automatically transferred onto the lower mold bead seat, a rubber bladder is inserted into the green tire ...
For this reason, the early cement industry used the "wet process", in which the raw materials are ground together with water, to produce a slurry, containing 20–50% water. Both Louis Vicat and James Frost used this technique in the early 19th century, and it remained the only way of making rawmix for Portland cement until 1890.
