The coating surrounding the graphite tubes can be a Teflon based coating, such as Tefzel, which can improve the durability of the graphite heat exchanger. The graphite tubes can be prepared by first coating the graphite tubes with the coating material and then curing or baking the graphite tubes in order to plasticize or otherwise cure the coating material.

Abstract: A drip emitter is described herein that is advantageously configured to allow large grit to pass through the drip emitter when in use. The drip emitter includes a housing containing a flow path extending between a water inlet and a water outlet, a pressure-reducing segment, such as a tortuous path, of the flow path downstream of the inlet and upstream of the outlet, and a dynamic pressure regulator downstream of the water inlet and upstream of the pressure-reducing segment of the flow path. The dynamic pressure regulator is configured such that a decrease in pressure in the pressure-reducing segment of the flow path causes the dynamic pressure regulator to adjust to maintain a generally constant rate of flow through the water inlet as compared to the rate of flow when there is no decrease in pressure in the pressure-reducing segment of the flow path.

The most common configuration consists of three different zones located inside the tank, namely: a hot zone in the upper part of the tank, enclosing an encapsulated phase change material characterized by a high melting temperature; a cold zone housed in the lower part of the tank, containing a phase change material with a low melting temperature; and a middle zone containing a sensible heat solid material.

Abstract: A fluid dispense tip includes a bevel at an opening to reduce the amount of surface tension, or “land”, at the opening. The bevel is formed by grinding in a longitudinal direction such that any tooling scars resulting from the grinding operation are likewise longitudinally oriented, further reducing the amount of surface tension in the tip, thereby leading to heightened dispensing accuracy. The tip may be machined from stock as a unitary piece, to increase its lifetime, and may be formed with a bore of a relatively large diameter that is tapered down to a smaller diameter near the tip opening, to allow for delivery of fluid through the tip body at a decreased pressure. A cleaning tool may be provided for removing residual material from the inner surfaces of the tip. A removable liner sleeve may be provided within the bore to reduce the effective inner diameter of the dispense tip.
