Patent DE-4315764-A1 (DE)
Title: Process and apparatus for desludging flat bodies of water
Inventor: WEIHER INGO
IPC: B63B35/44
Filed: 1993-05-07
Abstract: The invention relates to a process for desludging and sanitation and rehabilitation of flat bodies of water using a combined apparatus for sludge removal, the buffer vessels having a preseparator, the separation of water and solids (digested sludge and other solid constituents), the treatment of the end products up to supply to the end consumer and the post-treatment of water up to the attainment of drinking water quality and subsequent aeration. In this process, the contaminated water mixture, in the course of complete passage through a unit system, is divided in stages into solid constituents and water in accordance with the quality required. The overall unit system is composed of individual elements and may be constructed manually on site. The overall solution is constructed in an energy saving manner and may be extended by flocculation units for all pollutants (e.g. phosphorus, nitrogen) and palletising units for the solids. It is suitable for the treatment of agricultural waste products, e.g. liquid manure and for treating kitchen wastes for preparing feed for animal husbandry. This rehabilitation process, without vortexing the existing water layers which have built up, permits the object posed to be fulfilled without mixing the water layers. The advantage is that the natural relief and the bank region are retained without damage.

Title: Hydraulic control valve for agricultural machinery
Inventor: DUECKINGHAUS HEINRICH
IPC: F15B13/044
Filed: 1993-11-26
Abstract: The hydraulic control valve consists of a valve body (6) moving in an oil stream through a valve housing (4) that has three entries. There is a pressure pipe (12), a user pipe (13) and a control pipe (14) entry. The pressure pipe entry can be shut with a ball (9) supported by a spring (8) in which case the valve body is in its upper position and the user and control pipe are pressureless. When the valve body is moved downwards with the help of an electromagnet the pressure pipe entry opens and the control pipe entry closes. The valve body is exposed to the pressurised oil and the pressure on the valve ring base (6b) causes it to open the entry to the control pipe again.

Patent DE-4408920-A1 (DE)
Title: High pressure flow control switch valve
Inventor: HANAFI NABIL
IPC: B08B3/02
Filed: 1994-03-16
Abstract: The valve is connected between the high pressure feed and the high pressure line to the user. A dump line is connected to the valve to dump excess pressure when the valve is switched off. This removes excess pressure between the valve and the user and ensures a rapid switch off. An externally driven control piston (3) holds the control valve in the high pressure setting. When the external servo pressure is removed the internal pressure in the valve closes the high pressure connection and opens the dump connection, either on the pump side or, more usually on the user side. The control piston pushes a second control piston (9), with a central duct, closed by the first control piston. On removal of the servo pressure the second control piston is displaced by the internal pressure to seal onto a fixed seal. The first control piston lifts off the second piston and opens the dump path through the second piston.

Inventor: BARTELT HARTMUT DR
IPC: A61B8/00
Filed: 1994-08-11
Abstract: In an ultrasonic transducer array, the spacings of its transducer elements (Tij) decrease towards the outside in the row direction (x direction) and column direction (y direction) from a centre of symmetry (S) in accordance with the rule that the integral over a function f(x) and, respectively, g(y) falling off linearly and strictly monotonically towards both sides with respect to the centre of symmetry (S) between the centre points (Mij) of adjacent transducer elements (Tij) is constant for each row and column, respectively.
