    摘要: An air conditioning control system for at least two duct sections (14,86) each with an associated damper (18,84) comprises at least one master controller 10 for a first pneumatic actuator (20) for one damper (18) and at least one tracking controller (12) for a second pneumatic actuator (80) for the other damper (84). The master controller (10) comprises a first flow sensor (50,52,54) producing a first flow variable signal in response to a sensed flow in the duct section (14) associated with the said one damper (18). An adjustable reference or bias signal means is provided and a temperature signal is combined therewith to provide a composite signal for comparison with the flow variable signal. A resultant signal after comparison operates the first pneumatic actuator (20) for the said one damper (18). A tracking controller (12) comprises a second flow sensor producing a second flow variable signal in response to sensed flow in the duct section (86) associated with the other damper (84). A second signal comparison and transmitting means (98, 102, 104) receives the first and second flow variable signals, compares the two and transmits a second resultant signal to the second pneumatic actuator (80) for control of the said other damper (84).

    摘要: @ A liquid additive injection pump has a hydraulic motor comprising a differential piston assembly reciprocable in a housing under the urging of a primary liquid into which an additive is to be injected. The piston assembly includes valves to effect the transfer of a primary fluid charge from the pump motor to a discharge passage and to effect reciprocation of the piston assembly. The motor piston is connected to a central axially disposed piston rod which extends into an additive injection pump cylinder. In one embodiment a floating additive injection pump piston has a stack of displacement control washers engaged therewith and disposed on the piston rod. In another embodiment the pump piston passes through a seal member between a pump chamber and a bypass chamber and an elongated spiral groove formed on the periphery of the pump piston determines the effective displacement of the pump. A spring biased toggle type linkage snaps the motor valves into open and closed positions to provide positive movement of the valve members. Liquid additive is injected into the primary fluid stream at the outlet passage of the apparatus and downstream of the motor mechanism.

    摘要: A mixed gas concentration regulating method and a concentration regulating apparatus, in which the maintenance of the recovery of an easily permeable gas and the restraint of the power expense are compatible, are provided. A mixed gas concentration regulating apparatus which comprises a pressure raising line having boosters C11, C12 for raising the pressure of a mixed gas consisting of two or more gases different in permeability, a line L1 for leading out a part of the mixed gas from said pressure raising line, a gas separation section for separating the gas fed from said line L1 to a permeate gas and a retentate gas by gas separation membranes M1, M2, and a line for introducing said permeate gas into said pressure raising line, is characterized in that said gas separation section is composed of plural stages S1, S2, where respective stages are connected with each other by a line L3 for feeding a retentate gas of the preceding stage to a gas separation section S2 of the succeeding stage and lines are provided for introducing permeate gases of the respective stages into said pressure raising line separately or after they are joined, and the pressure difference of said pressure raising line is utilized so that the pressure ratio on the feed side and permeation side is made larger as in the gas separation section of the latter stage side.
