A second pump conveys fresh paint material into the pressurized vessel.

Abstract: In a solar heating system, using liquid for heat-transfer or heat-storage or both, the liquid may be lost slowly due to a leaky pipe connection, or a cracked or split absorber plate or collector pipes attached to the absorber of a closed type of collector, by evaporation through broken solar collector glazing of a trickle-flow collector, or such.A number of schemes have been proposed to provide makeup liquid. One is to allow makeup liquid, such as water, to flow backward from a large heat-storage vessel used during the winter to a smaller one which is the only one in use during the summer. That scheme was disclosed in a patent application filed by Dr. Harry E. Thomason way back in 1961. However, the backflow-connecting pipe had no check valve in it and therefore was of limited value.

Abstract: A valve includes housing and body members that have cylindrical valve surfaces. The valve body being centered in the housing by an array of at least three resilient support elements circumferentially spaced about the valve body. The valve body includes a plurality of ports arranged for selective alignment with housing ports as the valve body member is rotated and a through passage that connects two of the valve body ports. The resilient support members are apertured and conform in sealing engagement between the juxtaposed cylindrical valve surfaces so that they also function as annular valve seal members.

Abstract: The invention relates to a fluid reservoir with two compartments, more particularly for supplying hydraulic fluid to tandem master cylinders, this reservoir more specifically comprising two complementary, superjacent parts connected with adhesive, by thermowelding or by any other equivalent method, a central partition attached to the said parts and running across the longitudinal axis of the reservoir to divide the reservoir interior into two compartments having respective outlet orifices, at least one compartment also having a filler orifice, and the two compartments being interconnected by a transfer passage which extends into both of them and runs parallel to the surface of the fluid in the reservoir and substantially at the maximum level for this fluid. The transfer passage enables the hydraulic fluid to pass from one reservoir compartment into the other when the reservoir is filled with hydraulic fluid.

Abstract: A fuel tank having an upper compartment has a lower compartment separated from the upper compartment by means of a dividing member. The dividing member is sealably attached to the side walls of the fuel tank and has a small opening substantially centrally located therein. A first fuel tube extends through the top of the fuel tank into the upper compartment to a level near the bottom of the upper compartment. A second fuel tube also extends through the top of the fuel tank and through the opening in the dividing member to a level near the bottom of the lower compartment. A solenoid-activated valve is coupled to the first and second fuel tubes externally of the fuel tank. The selector valve is connected by means of a third tube to a fuel pump which pumps fuel from a selected one of upper and lower compartments to an engine. The selector valve is initially switched to select the upper compartments.

Abstract: A vehicle fuel tank has indentations on the bottom wall which form an internal pocket between oppositely facing surfaces of the indentations. A reserve tank is mounted in the pocket. In a preferred embodiment, the reserve tank is clamped by the surfaces using an elastic member with radial prolongations, at least some of which, in the assembled condition, are oriented in opposition to the direction of removal of the reserve tank.

Abstract: In a reservoir assembly for a tandem master cylinder of a hydraulic braking system the container is separated into compartments by at least one baffle passages being provided for permitting limited communication between the compartments past the baffle. The arrangement is such that when the container is installed in a vehicle and the brakes are applied, the tendency of fluid to transfer from one compartment to another is resisted. The arrangement also ensures that even under the worst conditions of deceleration and altitude of the vehicle there will be a sufficient volume of fluid in the compartments to cover outlets to the master cylinder and thus sustain subsequent brake application.

Abstract: Master cylinder reservoir comprising a housing having two adjacent reservoir sections separated by a transversely extending double wall partition having windows offset laterally from one another with a space between the walls.

Abstract: An automatic change-over system for stock rotation of liquids packaged in plural collapsible bag-type reservoirs is described. The bag-type reservoirs are divided into primary and secondary groups, the primary group containing the supply of liquid being dispensed and the secondary group containing the liquid supply held in reserve. Automatic change-over between the primary and secondary groups of bag-type reservoirs is effected in response to a vacuum created by the empty condition in the bags in the primary group. The pressure change in the present system is the result of the deflation of the empty bag-type packages. Thus, the change-over is caused by the characteristics of the flexible bags containing the liquid being dispensed.
