Example Output: The invention concerns a small-scale biological sewage treatment plant operated by fluid bed/biofilm technology for treating waste water. According to the invention, for the biological/biofilm treatment of the activated sludge a biostage (2) with an aeration device (4), which can be switched off, is arranged downstream of a preliminary sedimentation tank with a sludge reservoir (1) and a feed pipe (6). The biostage (2) is partially filled with growth bodies (5) having a colonizable area of at least 800 square meters per cubic meter of bulk volume and comprises a retention device (8) for retaining the growth bodies (5) in an obstruction-free manner. Disposed after the retention device (8) is a final sedimentation tank (3), which can be flowed through vertically and has a discharge (7), the parts of the plant (1 to 4) preferably being disposed in circular tanks. The retention device (8) can consist of a pipe in or over which a discharge pipe leads into the final sedimentation tank (3). The biostage (2) can further comprise a biofilter stage (9) into which lead the feed pipe from the preliminary sedimentation tank (1) and the feed pipe for returned sludge from the final sedimentation tank (3).

Example Input: Vynález se týká tavného lepidla, z.vláště  pro nalepování hranovacích pásků jak syntetických,  tak i dýhových, na boční stěny nábytkových  dílců. Je vhodné především pro  lepení automatickými olepovacími stroji.  Jeho podstata spočívá v tom, že obsahuje  44 až 51 % hmot. termoplastických látek, 22  až 28 % hmot. modifikované přírodní pryskyřice,  22 až 28 % hmot. anorganických plnidel,  2,5 až 4 % hmot. voskových komponent  a do 0,3 % hmot. antioxidačních přísad.
Example Output: BACKGROUND OF THE INVENTION The present invention relates to a hot melt adhesive  for sticking edge strips like synthetic ones  as well as veneer, on the side walls of furniture  parts. It is especially suitable for  bonding with automatic banding machines.  Its essence is that it contains  44 to 51 wt. thermoplastic materials, 22  % to 28 wt. modified natural resins  22 to 28 wt. inorganic fillers  2.5 to 4 wt. wax components  and up to 0.3 wt. antioxidant additives.

Example Input: Ventil sestává z ventilového tělesa (10) s vnitřní dutinou (24), uspořádanou mezi výstupním otvorem (15) ventilu a vstupním otvorem (28) ventilu a opatřenou přestavitelnou jednotkou pro otevírání a uzavírání vstupního otvoru (28) ventilu, který je pro umožnění rychlého nárůstu tlaku kapalného chladiva ve vnitřní dutině (24) po otevření vstupního otvoru (28) ventilu a pro jeho bezprostřední rychlé uzavření větší než výstupní otvor (15) ventilu. Chladicí zařízení obsahuje ventilový prvek, napojený na své výstupní straně na výparník (30), jehož výstupní konec je přes kondenzátor pro kondenzování plynného chladiva na kapalné připojen na vstupní stranu ventilového prvku, přičemž ventilový prvek je tvořen termostatickým expanzním ventilem, jehož otvor (11) je prostřednictvím tlakového vedení (31) propojen s teploměrnou jímkou (32), uspořádanou na výparníku (30) a upravenou pro vytváření ovládacího tlaku, uměrného teplotě par chladiva ve výparníku (30).ŕ
Example Output:
In the present invention, there is disclosed a valve assembly for pulsed operation between open and closed conditions comprising: one inlet port (28) for being open and closed during operation having an inlet flow area and a valve for opening and closing said inlet port (28), an open outlet port (15) having an outlet flow area, a valve cavity (24) between said inlet port (28) and said outlet port (15) and in open communication therewith, said valve being responsive to pressure within said valve cavity (24) for opening and closing said inlet port (28), and wherein higher pressure therein biases said valve to close said inlet port (28) and lower pressure therein biases said valve to open said inlet port (28), said inlet flow area being larger than said outlet flow area whereby opening said inlet port provides for rapid pressure buildup in said cavity and rapid closure thereof after each opening, whereby said valve is pulsed to rapidly open and close said inlet port (28) during said operation. Disclosed is also a refrigeration apparatus comprising a condenser for condensing refrigerant gas, an evaporator (30) for cooling a load in thermal exposure therewith, and a valve assembly for pulsed operation between open and closed conditions for controlling refrigerant flow comprising: an inlet port in communication with said condenser having an inlet flow area for receiving condensed refrigerant, and a valve for opening and closing said inlet port, an open outlet port having an outlet flow area and communicating with said evaporator for directing liquid refrigerant thereto, a valve cavity between said inlet port and said outlet port and in open communication therewith, said valve being responsive to pressure within said valve cavity for opening and closing said inlet port, and wherein higher pressure therein biases said valve to close said inlet port and lower pressure therein biases valve to open said inlet port, said inlet flow area being at least twice the size of said outlet flow area whereby opening said inlet port provides for rapid pressure buildup in said cavity and rapid closure thereof after each opening, whereby said valve is pulsed to rapidly open and close said inlet port during said operation.
