Abstract: A pressure regulating valve having a compression spring fixed in a valve housing for positioning a valve plunger connected to a magnetic armature in the position above a valve seat and not electromagnetically excited, in order to create a connection between at least two pressure medium channels opening into the valve housing, and having a further compression spring disposed coaxially to the first compression spring in the valve housing, having the characteristic that the first compression spring is designed as a control spring forming a stroke and force-specific spring drive by adjusting the spring rates of both compression springs to the force/distance curve of an electromagnet by varying the current in an exciter coil, wherein the further compression spring is designed as a variably adjustable spring acting opposite to the control spring.

Abstract: A quick coupler has a coolant supplier seat and a transmission seat that can be optionally connected or disconnected. When the coolant supplier seat is connected to the transmission seat, the coolant can flow automatically from the coolant supplier seat to the transmission seat, so as to cool down electronic components inside a rack. When the coolant supplier seat is disconnected from the transmission seat, the coolant instantly stops flowing into the transmission seat. Because of the quick coupler, the rack installed inside a narrow space is convenient to set up or disassemble.

Abstract: A two-axis solar tracker apparatus is disclosed having multiple dish-shaped monolithic reflectors for concentrating sunlight. The dish-shaped monolithic reflectors are co-axially aligned in an array supported by a moveable frame. The moveable frame forms the elevation structure of a two-axis tracker that has control means for following the movement of the sun across the sky. Each dish-shaped monolithic reflector produces a region of concentrated sunlight suitable for generation of solar energy. A generator is positioned at the focus of each reflector. A preferred generator uses photovoltaic cells to generate electricity at a high output power due to the high solar power input that is directed to the generator by the dish-shaped monolithic reflector.

The arrangement is such that as the rotating disc rotates, different streams of process liquid streams fed to the rotating disc through the rotating pipes are introduced to fixed ports in the stationary disc. The latter ports are arranged to feed the streams selectively to selected destinations.
