Title: Process for separating a suspension under pressure in a filter press having membrane filter chambers
IPC: B01D25/168
Filed: 1985-02-07
Abstract: A process for separating a suspension under pressure, in a filter press having membrane filter chambers, into a solid component, the cake, and a liquid component, the filtrate. A membrane filter chamber is formed by a filter plate and an associated frame. A pressing or segmented belt is stretched across the lower side and upper side of the frame. A pressing membrane is arranged between the filter plate and the frame. A free space formed by the filter plate and the frame is divided into a pressure space and a pressing space, the pressure space being arranged in the filter plate and the pressing space being arranged in the frame. Feed and discharge lines are arranged, the pressing space being filled with suspension via at least one feed line and then the pressing space being impinged by a pressure medium in such a way that the pressing membrane is pressed into the pressing space and, as a result, the suspension is compressed. By means of the arranged pressing belts or segmented belts, a separation into filtrate and cake is effected. The filtrate is drawn off and the cake is discharged after completion of the separation process. Prior to filling the pressing space with suspension, the pressure space is evacuated. After the pressing space has been filled with suspension, the reduced pressure in the pressure space is relieved and atmospheric pressure is introduced. The pressure in the pressure space is then increased to superatmospheric pressure and gradually increased to a highest pressure, ... Original abstract incomplete.

Title: Transport apparatus for filter plates
Inventor: FREY WOLFGANG
IPC: B01D25/172
Filed: 1986-03-17
Abstract: The invention relates to a transport apparatus for filter plates of filter presses, as used for the preparation of masses in the ceramics industry. The aim of the invention is to create preconditions for the light engineering construction of such a transport apparatus and thus to make possible relatively simple retrofitting capacity of existing filter presses. The aim of the invention is achieved by outfitting a carriage, which can travel above the filter plate package, with two angled arms extending laterally to about the centre of the filter plate, to each of which arms is connected a vertically pivoting piston-cylinder drive. A cam is mounted on the piston rod of said drive, while to receive the counterforces, a retainer supported against the filter plate package is arranged on the side of the cylinder facing away from the centre of gravity of the piston-cylinder drive. A vertically-acting working cylinder serves for the pivoting motion of the piston-cylinder drive. The arrangement according to the invention of cam and retainer avoids the introduction of reaction forces into the frame construction. The invention is used in the ceramics industry. <IMAGE>

Title: Failsafe AND gate
Inventor: THOET REINHOLD DIPL ING
IPC: H03K19/007
Filed: 1986-06-20
Abstract: For a failsafe AND gate through which at least one dynamic signal passes, the criterion for the forwarding of this dynamic signal fed in at the input being that an associated static input signal is in the logical one range, a more simple configuration not containing any special components but only commercially available components and, nevertheless, fully meeting the required safety levels, is to be achieved. This object is achieved by the fact that the AND gate consists of an input network (I), an output network (II) and an intermediately located switching stage (V1) which is controlled by the static input signal (Ue) via a constant current source (III), the dynamic signal (Ude), which is applied via the input network (I) to the switching stage (V1), being conducted from there to the circuit output (C) via the output network (II). It is appropriate for the input network (I), which essentially consists of series-connected coupling capacitors (C1, C2) and an interconnected shunt-connected clamping diode (V2) with the forward direction to earth, to be connected to the gate (G) of a field-effect transistor as switching stage (V1), the drain terminal (D) of which is connected to the output network (II) and via its drain resistor (R1) to the constant current source (III), and the source terminal (S) of which is connected to earth. This results in a simple electrically and thermally stable circuit. <IMAGE>
