Abstract: The bath (4) is arranged the supply reservoir (5) for the liquid (3), in which the reaction flask to be heated or cooled can be immersed. The heating or cooling device (8) is arranged on the bottom of the supply reservoir (5). The liquid (3) is delivered with an immersion pump (19) through a feed pipe (6) and an opening (18) in the bottom of the bath (4). The level of the liquid in the bath (4) can be adjusted with the aid of a slider (11). The liquid flows back into the supply reservoir (5) over an overflow (7). When the pump (19) is switched off, the liquid (3) in the bath (4) flows independently back into the supply reservoir (5).

Abstract: A pasteurized to raw liquid processing system for milk or milk products includes top and bottom tanks, one elevated above the other approximately two feet. The tanks are vented to atmosphere. To prevent foaming, the inlet from a pasteurized source to the top tank is below the liquid level and the same is true of the inlet to the bottom tank which via a throttle valve receives liquid from the bottom of the top tank. Automatic feedback level controls are provided. Since both tanks are vented to atmosphere and because of the gravity flow between the top and bottom tanks, it is impossible to have a vacuum or pressure buildup which would cause a contaminating back flow.

Abstract: A viscous fluid pumping system having a pair of opposing gears (130, 132) is provided in a housing (32) disposed above an inlet port (73) in a follower plate (70). The follower plate (70) is dimensioned to sealingly fit in a container or drum (D) filled with highly-viscous fluid. In operation, the gears generate a vacuum between the follower plate (70) and the viscous fluid, allowing atmospheric pressure to press the follower plate into the viscous fluid. This, in turn, forces the fluid through the inlet port (73) and into the gears (130, 132). The gears exert high shear forces and localized heating to the fluid, decreasing its viscosity. The fluid exits the system through an outlet in the gear housing. The pumping system may use two such pumps working in conjunction or incorporate a single such pump with a valve structure for recycling fluid through itself.

The primary gravity feed system defined thereby isolates each tank from the other, thereby preventing large fuel excursions during extreme flight maneuvers.

Abstract: When using containers of agricultural chemicals, such as herbicides, pesticides and the like, it is desirable to transfer the contents to the sprayer tank by pump means rather than physically lifting the container to the tank inlet and then pouring the contents manually into the tank. It is also essential to rinse out the container prior to disposing of same as most of the chemicals used are concentrated and can cause environmental damage if the majority of the contents are not removed prior to disposal. The present device allows the operator to transfer the chemical to the tank by means of a pump and then wash or rinse out the container with water which is then also transferred to the sprayer tank. A control valve portion connects to a concentric tube assembly which includes a container piercer on the lower end thereof.

Abstract: A reaction product is formed by a process which involves the transfer of the reaction product from an autoclave to a receiving vessel at a substantially constant flow rate. Just prior to this transfer, the pressure in the receiving vessel is brought up to the pressure in the autoclave by passing gas from the autoclave to the receiving vessel. The flow of gas from the autoclave to the receiving vessel is then stopped, and the pressure in the receiving vessel is allowed to drop due to transfer of heat from the gas to the walls of the receiving vessel. The resulting pressure difference between the autoclave and the receiving vessel is used to initiate the transfer of the reaction products from the autoclave to the receiving vessel. A pressure release valve on the receiving vessel is then controlled by means a signal derived from a flow meter which measures the flow rate of the reaction products flowing from the autoclave to the receiving vessel to maintain constant this flow rate.
