Patent DE-3147448-A1 (DE)
Title: Device for simulating an environment
Inventor: DUX HELMUT DR RER NAT
IPC: G09B9/00
Filed: 1981-12-01
Abstract: A device for simulating an environment with essentially static background and quasi-resting and moving objects as represented to a stationary observer is specified in which the background image is generated separately from the image of objects moving in front of it for the purpose of representing a synthetically generated background image with unrestricted variety of detail when the data transmission capacity is limited. The digital images of background and moving objects are in each case stored separately and correctly positionally allocated to one another in separate image repetition stores, the static image store and the dynamic image store, which are synchronously read out. A video switching device connects a video display device to the static image store and switches the former to the dynamic image store as soon as a digital image signal is read out there so that the moving object always appears to be covering the background for the observer in the visual image generated by the video display device.
Patent DE-3150140-A1 (DE)
Title: Process and equipment for biological effluent treatment
Inventor: MORPER MANFRED DIPL CHEM DR
IPC: C02F3/30
Filed: 1981-12-18
Abstract: The invention relates to a process and to equipment for biological effluent treatment, the effluent also being denitrified, inter alia, in a treatment tank (11) having anoxic conditions. To ensure nitrogen removal which is as complete as possible and is to be carried out in a simple and economical manner, the denitrification should be carried out in the presence of effluent sludge as a reducing agent. For this purpose, especially the excess sludge is used which arises in the effluent treatment plant and has been taken off from intermediate and final clarification tanks (3, 13). This excess sludge is first dehydrated in a thickener device (22), mechanically, thermally or chemically digested in a device (23) and then freed of nitrogen in an ammonia-stripping device (24). The sludge thus treated is then fed via a line (21) to the denitrification tank (11). <IMAGE>

Title: Control for the joint of four-axled rail vehicles, in particular trams
Inventor: KLEIM KARL-HEINZ
IPC: B61D13/00
Filed: 1982-02-17
Abstract: The invention relates to a control for the joint of four-axled rail vehicles, in which the two carriage bodies (2, 2a) are mounted on one bogie (13b, 13a) in each case and are connected in their centre by means of a joint (12). Since this joint (12) requires a control so as not to migrate inadmissibly when going round bends, it is proposed according to the invention that the secondary springs be constructed as solid-rubber or flexicoil springs since the latter exert a torque on the carriage body (2a) via the front bogie (13a), whilst by means of the secondary springs of the following bogie (13b), restoring moments are exerted on the wagon body (2), so that the position of the joint (12) is automatically set in the desired manner due to balancing of the moments when the tension in the secondary springs is released. <IMAGE>

Title: Shears for cutting moving rolled material, in particular hot-rolled strip
Inventor: BENZ WILLI
IPC: B23D25/06
Filed: 1982-06-01
Abstract: Cutting shears for moving hot-rolled strip (25) are designed in a technically simple manner so that the front and rear ends of the hot-rolled strip receive a different cutting edge profile, and so that it is also possible to cut up relatively long hot-rolled strips (25) into several strip sections while retaining the corresponding cut edge profile. For this purpose two pairs of knives (22', 24' and 22'', 24'') are arranged in a floating frame (9) suspended in the shears stand, in such a manner that in each case the lower knives (24' and 24'') are held by a knife carrier (9'') in the floating frame, while the upper knives rest on a knife carriage (12) which can be moved by a mechanical drive and runs in a displaceable manner in guides (13) in the floating frame (9) relative to the knife carrier (9'') in the cutting direction. The knife carriage (12) together with its longitudinal centre plane is exclusively guided in a displaceable manner in the direction of the longitudinal centre plane x-x of the floating frame (9) and both pairs of knives (22', 24' and 22'', 24'') can simultaneously be brought into the cutting position. The upper knives (22', 22'') are arranged on the knife carriage (12) with their knife fronts facing away from one another, while the lower knives (24', 24'') are arranged on the knife carrier (9'') of the floating frame with their knife fronts facing one another. Both pairs of knives (22', 24' and 22'', 24'') are arranged symmetrically relative to the common longitudinal centre plane x-x of the floating frame (9) and knife carriage (12). <IMAGE>

Patent DE-3223179-A1 (DE)
Title: Power supply circuit
Inventor: RIEDGER THOMAS DIPL ING
IPC: H02J1/10
Filed: 1982-06-22
Abstract: In a power supply circuit having at least two voltage converters which are single-ended converters, the inputs are connected to a common voltage source. All the voltage converters operate at the same switching frequency. The duty ratio is controlled by a separate control circuit in each voltage converter. The voltage converters are split into two groups in such a manner that a synchronisation circuit of each group prescribes a first time interval in push-pull operation, in which interval the voltage converters may be in the conducting phase, and prescribes a second time interval in which the voltage converters must be in the blocking phase.

Title: Line connection unit
Inventor: PARRAS KARL-HEINZ DIPL ING
IPC: H04M19/08
Filed: 1982-07-10
Abstract: To connect a subscriber station to a telecommunications line, line connection units are used whose input resistors assume a predefinable resistance value. If pulsating signal components are added to a loop current, a predefined dynamic input resistance and a DC input resistance must be maintained. In the case of low loop currents, the DC input resistance is defined by a control resistor. If an active impedance is provided in parallel with the control resistor, a compromise between the latter's amplification factor and the value of the control resistor is required. The dynamic response of the line connection unit is no longer affected by the control resistor if the latter is disposed downstream of the control circuit for the active impedance. For this purpose, a second pole of a voltage-controlled voltage source is connected to a first terminal of the control resistor and to the anode of a diode. A second terminal of the control resistor is connected to earth and the cathode of the diode is connected by one terminal to a shunt controller for generating the operating voltage. A further voltage-controlled voltage source, a further control resistor and further diodes can be provided to ensure that the line connection unit is connected to the telecommunications line with the correct polarity.

Title: Method and device for the protection of parts of the dentition of ruminants
Inventor: LATTERMANN JOERG-PETER DR MED
IPC: A61D5/00
Filed: 1983-05-05
Abstract: For the protection of parts of the dentition of ruminants, especially sheep whose front teeth are arranged at a distance from the molars, it is intended to provide a method and a device which permits economically reasonable treatment of parts of the dentition, especially of the front teeth of sheep, by the animal keeper himself in a manner tolerated by the animal. This is achieved in that a profiled protective rail which reaches over at least the crown surfaces of the front teeth is pressed, with interposition of a plastic, curable material as the binder, onto the front teeth, and is held there until curing is complete, it being possible for the plastic material to be admixed with at least one bacteriostatic additive, for example, copper ions, before its application. The device required for this purpose comprises a partially circular profiled groove in plan view having an approximately U-shaped or V-shaped cross-section which tapers towards the end.
