摘要： The system provides for one or more photovoltaic panels (3) or other energy sources, connected to a series of inverters (5) in parallel, the outputs of which are connected to a load (Z) and/or to an electricity distribution grid (7). One of the inverters operates as master unit and generates a power control signal in order to track the maximum power point that can be obtained from the panels (3). The other inverters operate as slave units. The control is performed so that all the inverters absorb a variable quantity of power according to the fluctuations in the power available at the output of the photovoltaic panels (3) or other source subject to fluctuations.

摘要： An overhead door, which is adapted to have its primary tracking members temporarily disengaged from their primary track when impacted by a substantial force when in the closed or partially closed position, is adapted to smoothly transition from its vertical, closed position to a non-vertical, open position by the use of second tracking members and track which come into use as the door panels transition from a vertical orientation to a non-vertical orientation. The impact caused disengagement feature is therefore effective without interference from the second tracking members, but progressively gives way to the second tracking members and track as the door is raised toward an open position.
摘要翻译：适于在其处于闭合或部分关闭位置时受到相当大的力的冲击时使其初级跟踪构件临时脱离主要轨道的顶部门适于从其垂直的关闭位置平滑地过渡到非垂直，通过使用第二跟踪构件的打开位置和随着门板从竖直方向向非垂直取向转变而被使用的轨道。因此，不会受到来自第二跟踪构件的干扰而产生的脱离特征的影响是有效的，但是当门向着打开位置升高时逐渐地让位于第二跟踪构件和轨道上。

摘要： A temporary barrier chain for a loading dock door opening includes a vertical orientated storage tube on one side of the opening and a retainer on the other side thereof, and a counterweighted chain extending from inside the storage tube to a retainer on the other side of the opening, with the chain being comprised, at least partially, of successively lighter weight sections toward the retainer end such that the combined weight of the counterweight and suspended chain within the storage tube will cause the chain to be automatically retrieved into the storage tube when released from the retainer.

摘要： A laminar flow air mover includes a cylindrical fan having an outlet opening connected to a conduit system. The conduit system includes a first portion connected to the outlet portion of said centrifugal fan and an outlet portion detachably connected to the first portion by a reusable breakaway connection. A baffle plate is pivotably mounted in the outlet of said outlet portion and extends transversely of said outlet portion to direct a coherent flow of air for a substantial distance in the desired direction.

摘要： A circuit for controlling the power supply voltage of an electric motor includes means for detecting the difference between a mains voltage and a reference voltage, and means for generating alternating correction voltage whose frequency is equal to the frequency of the mains voltage and which is phase-shifted with respect to the mains. The phase shift between the mains voltage and the correction voltage is proportional to the between the mains voltage and the reference voltage, and the correction voltage is added to the mains voltage.
