An illustration of a Geissler pump. A pump is a device used to move fluids, such as gases, liquids or slurries. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure they only displace fluid causing a flow. Adding resistance to flow causes pressure.

"In the manufacture of artificial ice, ammonia is liquefied by being compressed by powerful pumps; then the liquid ammonia is cooled by passing cold water over the pipes containing it. the liquid ammonia is distributed through pipes, where it evaporates rapidly. The gas is drawn back by the pump, condensed to a liquid, and used again. The pipes in which the evaporation takes place are immersed in a strong salt solution, which, by furnishing heat for evaporation, is cooled to a point below the freezing-point of water." -Brownlee 1907

"A Retort is a vessel in whose chamber an object is subjected to distillation or decomposition by heat, a neck conducting off the volatile products. The retort of the chemical laboratory is a vessel of glass, platinum, porcelain, or other material. It is bottle-shaped, having a long neck attached, in which the products of the distillation are condensed, and from which they pass into the receiver. The retort of the gas works is a cylinder or segment of a cylinder, formed of clay or iron."—(Charles Leonard-Stuart, 1911)

"The most common way of determining the density of such a body [that is heavier than water] if it is unsoluble in water, is to find its weight in air (w); find its weight when immersed in water (w'); divide the weight in air by the loss of weight in water." -Avery 1895

A siphon (also spelled syphon) is a continuous tube that allows liquid to drain from a reservoir through an intermediate point that is higher, or lower, than the reservoir, the flow being driven only by the difference in hydrostatic pressure without any need for pumping. It is necessary that the final end of the tube be lower than the liquid surface in the reservoir

"The light to be studied is admitted through a narrow slit (A) in the end of a tube, in such a way that it will fall in parallel rays on a prism (C) with its edges parallel to the slit. When the beam emerges from the prism, the different colors are separated and the spectrum is viewed through lenses (E) placed at the end of another tube." -Brownlee 1907

"The sulphur is then further purified by heating it in iron vessels (retorts) without access of air, until it is vaporized. the vapor is led into brick-lined rooms. A part of the gas is suddenly cooled and is deposited as a fine powder on the sides of the room. The form is known as flowers of sulphur. Most of the sulphur vapor condenses in the liquid form, and flows down to the outlet of the condensing chamber." -Brownlee 1907

Diagrammatic representation of the sulphuric acid contact process. "Sulphur, or ores containing sulphur, are burned in air. The sulphur dioxide and the other gaseous products of the combustion are cooled, freed from dust, arsenic, and most of the moisture, then mixedwith air and passed through a tube containing a catalytic agent, usually finely divided platinum. The oxygen of the air cmbines with the sulphur dioxide and forms the trioxide, which is then combined with water to form sulphuric acid." -Brownlee 1907
