Title: Industrial sludge floatation plant - has cells with air and sludge flow in opposite directions with baffle plate between
Inventor: NANZ HANS-HERMANN DIPL ING
IPC: B03D1/14
Filed: 1978-11-20
Abstract: The plant is fitted with cells mounted on housing plate (2) and consisting of air supply (3) and sludge supply flowing in opposite directions. The air enters the cell space (7) via outlet (6) where at a distance (w) a baffle plate (5) is fitted. The sludge is supplied to the cell space (7) via pipe (1) and flows against the conical diverting element (10) fitted on the underside of baffle plate (5). The sludge glides along the conical surface of diverting element (10) and after leaving edge (8) of the diverting element (8) creates a negative pressure in the gap (w) hereby increasing the effect of the pressurised air flow and producing evenly distributed bubbles in the sludge. To further increase this effect, several more baffle plates can be provided with gaps (w) between them and radial slots are provided in the air supply pipe (3) to admit the air into these gaps.

Title: Support struts for articulated trailer - use limited pivot action to raise and lower front of trailer
Inventor: RICHTER REINHARD DIPL ING
IPC: B60S9/04
Filed: 1978-12-04
Abstract: The front of the articulated trailer has non-telescopic support struts (9) which passing through a tilting guide at the side of the trailer, on each side. The length of each strut is fixed by inserting bolts through one of series of locking holes through the guide and strut, while the pivot action is locked by another bolt.

Title: Fault indication for seven element LED display - compares element voltages of two independent displays with time shared values passed to logic gate tree
Inventor: KALLINA UTA DIPL ING
IPC: G09G3/14
Filed: 1979-04-11
Abstract: With two independent 7-element LED displays, driven by the same data input, a fault in either of them is detected by comparing the voltages on corresponding elements using 7 comparison circuits. A significant difference detected by any of the 7 cirtuis lights a 'fault' lamp. The comparison circuits themselves are checked by switching off the data and applying a test voltage to each of the 14 inputs in turn, using a shift register. Failure to detect the test voltage lights a fault lamp. The digits of a multi-digit display are time shared. The time sharing voltages are compared in a logic gate tree to detect if any two overlap. If so, a fault lamp is lit. If only one display is needed, the second may be a dummy, formed of resistors and diodes.

Title: Visual digital indicator circuit - has transistorised timing and driving circuits for seven-segment indicator providing two brightness levels
Inventor: MUELLER HORST
IPC: H03J1/04
Filed: 1979-12-21
Abstract: The circuit for the optical indicator consists of two switches (10,11), which are connected with the trigger input of a timing circuit (13) via an 'OR' gate (12). The output of the timing circuit (13) is connected to the bases of two switching transistors (16,17) via respective feed resistors (14,15). The emitters of both transistors (16,17) are connected to ground and the collectors are connected respectively to the inputs of two seven segment indicater units (18,19), which display, when fed with current under the correct circuit conditions. When either switch (10,11) is operated, the timing circuit is triggered and current flows to the indicator units (18,19) since the inputs are at ground during the half period of the circuit. After the held time, both transistors (16,17) are blocked and one indicator goes out. The other indicator displays a lower brightness since current flows via a parallel zener diode (20). The circuitry can be used for channel selection or other functions in radio receivers, where two levels of brightness are required.

Title: PBX with internal dialling - provides extensions in main and secondary networks with call protection
Inventor: JAEGER HORST
IPC: H04Q1/44
Filed: 1980-02-28
Abstract: The telephone system produces signals indicating 'extension free' and 'extension engaged' using main and secondary codes. A special code describing a calling extension is appended to the two signals. The special code triggers a free tone at the calling subscriber without linking the called subscriber when incoming calls occur and triggers a call to an operator's set when incoming exchange calls occur. The special code acts as call protection and its release by an extension causes a monitoring code to be switched in after a given time at the operator's set.

Title: Oxidising water treatment - in oxygen diffuser and in ascending vortex produced in biological reactor
Inventor: MULOT ROBERT HENRI
IPC: C02F3/20
Filed: 1980-04-26
Abstract: A biological cleaning system of water to produce drinking water by oxidn. of the contaminants is based on saturating the water in a diffuser with air or oxygen. The stream is admitted to another tank where it rises in fluid vortex to effect a bacterial oxidn, of the contaminants. Clean water is discharged by an overflow and the sludge is extracted from the bottom. An impeller (8), driven by the motor (9), urges the water (7) which has arrived in the recption tank (1) through pipe (2), into a Venturi (5). Oxygen is admitted through an immersed diffuser (12), containing a porous cartridge (15) along spiral tubes (17) to which the pipes (19,20,21) admit aluminium sulphate, a flocculant, and activated carbon. This saves chlorine and prevents the formation of chlorophenolics. The power consumption is reduced to a min. and the formation of bubbles has been eliminated.

Title: Changeover circuit for anti-parallel three=phase bridges - displaces changeover time-point to minimise output current symmetry
Inventor: NEUPAUER HELMUT DR
IPC: H02M5/27
Filed: 1980-06-10
Abstract: The changeover circuit causes the time when changeover from one 3-phase bridge to the other to follow the phase shift between the passages through zero of the ac output voltage and the passages through zero of the ac output current's fundamental frequency. The asymmetry of the output current with time is measured. This asymmetry increases with the increasing difference between load angle and changeover angle. The asymmetry is determined by measuring the current flowing through one of the converter's outputs and is described by an electrical signal which is used to shift the changeover angle until the signal is a minimum.
