摘要： A solar panel having venting gates at opposite ends of an air plenum defined between a collector element and a protective, light-transmissive cover and having a wax thermal actuator for both the gates and flexible force-transmitting linkages between the actuator and each gate to operate the gates simultaneously. Preferred embodiments include certain linkages, gates and gate control apparatus, and certain structural relationships of the actuator with the collector element to achieve desired heat transfers. In certain embodiments, the actuator is part of a heat-sensing module which receives a multiplicity of heat inputs. The collector element in certain highly preferred embodiments is of plastic. A glazed solar panel having a venting gate controlled by a temperature-responsive wax thermal actuator linked thereto.

摘要： A regulator for maintaining a constant partial vacuum in a region, such as in a piece of process equipment or a fume hood. The regulator includes a path, through which fluid passes from the region to the vacuum source, and a movably mounted piston. The piston is disposed in the path so that the piston may constrict the path at a constriction point. Fluid in the path upstream of the constriction point exerts a pressure on the frontal face of the piston that tends widen the path at the constriction point. The piston is mounted so that the weight of the piston exerts a force on the piston in a direction that tends to widen the path at the constriction point. A force is exerted on the piston, preferably by a spring under compression, in a direction that tends to narrow the path at the constriction point. A buffering gas, introduced to the area between the piston's skirt and the piston mounting structure, may be used to keep noxious fumes from backing up into the environment and/or to provide an efficient bearing.

摘要： A regulator including a movably, preferably hingedly, mounted member having a distal face, exposed to a reference pressure, and a frontal face, exposed to fluid passing through the regulator. Attached to the member is a structure that variably impedes fluid flowing through the regulator. The amount that this structure impedes the fluid flow varies as a function of the difference between the pressure of fluid on the frontal face of the member and the reference pressure. The impeder may be an integral part of the piston extending into the path of the fluid flowing through the regulator, or it may be a separate structure attached to the member. As the member moves in response to changes in pressure differential across the piston, each movable segment is displaced with respect to its corresponding fixed segment. As the corresponding segments are further displaced with respect to each other, the impedance to flow increases. A restoring force or torque exerts a force on the member so as to tend to lessen the resistance on the fluid flow, and so that when there is no flow through the passageway the resistance is relatively low. The member may be mounted at the top of the regulator in order to make the regulator easy to clean to clean and maintain. A dashpot may be included in the regulator so as to reduce high-frequency oscillations that may occur in a finely tuned regulator. The regulator may include a bypass channel that permits a portion of the flow to bypass the impeder. A variable throttle valve mounted in the bypass channel is used to adjust the effect of the bypass channel.

摘要： To control the flow of air into andr out of a process chamber, such as a clean room, a two-stage system is disposed within each of several parallel conduits leading into and/or out of the process-chamber. One stage includes a regulator, having a plenum disposed between the environment and the vacuum source. The regulator maintains in the plenum a pressure that is between the pressures of the environment and the vacuum source and that is a constant amount different from the environment's pressure. The regulator includes a piston having a frontal face exposed to air in the plenum flowing between the environment and the vacuum source, and a distal face exposed to the environment's pressure. The piston is mounted so as to variably impede the flow of air through the regulator and so that the weight of the piston tends to move the piston in a direction so as to lessen the piston's impedance on the air flow. The other stage includes an adjustable valve located between the regulator and the environment, for further impeding the flow of air.
