Patent DE-3639277-A1 (DE)
Title: Remote control switching or control device esp. for mine warfare - operating by the pyrotechnic generation of acoustic impulses within a coded sequence
Inventor: GUEDESEN ALWIN DIPL ING DR
IPC: F42C13/06
Filed: 1986-11-17
Abstract: A remote control switching or control device, whereby a number (at least one) of receiver circuits are activated by acoustic impulses generated from a pyrotechnic explosive emitter (10). The emitter (10) generates a number of impulses. The receivers have several receiver channels at different frequency bands within the emitter frequency range. Each receiver channel has an impulse detector and the output from each of these are combined in a logical AND-gate. A comparison circuit compares the results of the AND-gates with a coded emitter signal and if agreement is obtained an activation signal is sent. USE/ADVANTAGE - The remote control device is especially intended for mine warfare. A number of mines within a mine field having been laid out, a sender device is then used to arm them all. Due to the coded nature of the emitter signal that can be sent out, a high degree of security is obtained against third party intervention or against a false arming of the mines.

Title: Compressed-air compressor
Inventor: SCHNEIDER WILFRIED
IPC: F04B39/00
Filed: 1986-11-18
Abstract: The compressed-air compressor according to the main application, which can also be used as spray device for liquids or pulverulent substances, has its range of application further increased by the fact that, between its compressor assembly part (18) and its pressure vessel, there is interposed a compressed-air supply vessel (40) which, together with the compressor assembly part (18), can form a separate compressor part (44) detachable from the remainder of the device. An additional extension of the range of application can be achieved by mounting a pump (5) on the pressure vessel which in this case serves as a pressureless material vessel. <IMAGE>

Title: Output circuit for a three-channel sequential circuit
Inventor: ZAGORNI PETER DIPL ING
IPC: H03K19/23
Filed: 1986-11-26
Abstract: A three-processor system is intended to control a load directly via the output circuit and it must be possible to tolerate the failure of one processor. Control commands are output via output switching means associated with each processor. Their switching paths (ASE1/1, ASE1/2, ASE2/1, ASE2/2, ASE3/1) form a network via which the load is to be connected. The operability of the output switching means is tested with each switching-on and -off of the load. For this purpose, two voltage sensors and one current sensor (U, V, J) are provided. The output switching means are successively operated in a fixed order and the switching state pattern of the sensors occurring during this process is compared with an expected switching state pattern. The load circuit is interrupted if there is a deviation from this pattern. <IMAGE>

Title: Process and apparatus for the jet cleaning of a stormwater tank
Inventor: DUERRINGER HERBERT
IPC: B08B9/093
Filed: 1987-01-02
Abstract: Process for the jet cleaning of a stormwater tank by means of at least one jet pipe. Up until now, the jet pipe was arranged such that it could not move and generated a circulating waste-water flow. Deposits on the bottom of the tank were removed often only to an unsatisfactory degree. The jet pipes, or at least one jet pipe, are displaced such that, consequently, any deposits located on the bottom of the stormwater tank are channelled away, at least to a considerably greater extent than was the case without this displacement of the jet, out of the stormwater tank along with the wastewater flowing out of the latter.

Title: Drum for removing and individually separating grains of seed
Inventor: BOETTCHER GUENTER
IPC: A01C7/04
Filed: 1987-01-16
Abstract: A drum (7) for removing and individually separating grains of seed has a drum body (23) which is surrounded by a casing (24) comprising individual strips (26) of thin material. These strips are in each case provided with at least one row (27) of holes, against the holes (6) of which the grains of seed are held by means of suction air. The very small bore length, which is determined by the material thickness of the casing strips, and the favourable diameter/length ratio of these holes (6) which is thus achieved avoids blockage of the holes by dirt and ensures the continuous function of the seed-grain receptacles formed by these holes. <IMAGE>
Patent DE-3714271-A1 (DE)
Title: Evaluating circuit for inductive encoder
Inventor: HENNING MANFRED
IPC: G01D3/032
Filed: 1987-04-29
Abstract: Such evaluating circuits are used for converting the inductive encoder signal, which is present as positive and negative sinusoidal half wave, into squarewave signals which are supplied to an electronic controller. At higher frequencies, an increase in the inductive encoder signal occurs and, in parallel, also in noise voltages which can be evaluated as usable signals. It is therefore provided that the output of a comparator is connected via a feedback branch with a series-connected resistor and capacitor to the positive input of the comparator. This provides for an application in motor vehicles which have known high noise voltages.

Title: Process for purifying waste water
Inventor: GEISE HEINRICH
IPC: C02F1/52
Filed: 1987-07-23
Abstract: To purify waste water, catalytic oxidation methods or biological processes are used. The majority of industrial and municipal waste waters (effluents) contain oxidisable substances of organic and/or inorganic origin. However, the known processes, alone or combined, do not give satisfactory results with respect to the residual values for the pollution. To improve the degrees of degradation, i.e. reducing the residual values for the chemical oxygen demand COD and the biological oxygen demand in 5 days BOD5, a process is proposed in which, in one sedimentation stage, the activated sludge forming in the reaction tanks for the catalytic oxidation is separated off and returned, as a result of which the biologically caused degree of degradation is greatly increased and the total degradation efficiency after the precipitation/flocculation is significantly improved in comparison to the purely catalytical oxidation. Purification of industrial and municipal waste waters.

Patent DE-3728792-A1 (DE)
Inventor: ROTTMANN DIETER
IPC: H04J3/06
Filed: 1987-08-28
Abstract: In the digital processing of signals, it is important that synchronisation words contained in the serial data stream are reliably detected. In a circuit arrangement for detecting and/or monitoring synchronisation words contained in a serial data stream, a first shift register is provided into which the data stream is continuously written. The storage cells of the shift register are logically combined via a logical AND gate, at the output of which a first detection and monitoring signal occurs. The first shift register is followed by a second shift register into which the data stream read out of the first shift register is written. A first nominal value is loaded into the first part-shift register by the detection signal. The outputs of the first and second shift registers are logically combined by a logic gate at the output of which a second detection and monitoring signal occurs. The circuit arrangement can be applied for detecting synchronisation words in digital audio broadcasting.

Title: Variable floating suction system for drawing off and removing liquid hydrocarbons and fuels on open water and inland water and solid substances which have sunk to the bottom
Inventor: FELKEL GUENTHER
IPC: E02B15/04
Filed: 1988-03-10
Abstract: The invention relates to a method as well as to three different ways of carrying out the method of drawing off unconcentrated, liquid hydrocarbons and fuels with the floating suction system I. The concentrated liquid hydrocarbons are drawn off with the floating suction system Ia. The floating suction system Ib has the task of sucking up the solid substances which have sunk to the bottom. Several identical floating suction systems coupled together result in wide suction areas. The number of suction systems is increased by extending the individual floating suction systems. Curved to circular suction areas are obtained through the use of additional couplings (7). The liquid-control slide (15) is fitted in the suction systems 4, 9, 5, 10. The adjusting ring (20) is pushed in the same suction systems over the wide suction slots, is set according to the film thickness of the liquids to be drawn off and is clamped in place by means of locking screws. <IMAGE>

Title: Method and device for vacuum-pressure shock freezing using liquefied gas
Inventor: SCHMIDT EDWIN
IPC: F25D31/00
Filed: 1988-03-31
Abstract: In this method, the material to be frozen is first subjected to a vacuum action and then gas acting as coolant and pressurising medium is fed in against it. For this purpose, liquefied gas is introduced into an evacuated container containing a material to be frozen. Using direct evaporation volume expansion, the container pressure exceeds the filling pressure, so that the suppliable cooling capacity is not sufficient for freezing. The features according to the invention make it possible to introduce the necessary total liquid-gas quantity in a single step into the liquid-gas absorber in the container and cause its automatic distribution to the material to be frozen, so that the cryogenic gas resulting from the expansion occurring in parallel with the direct evaporation acts as a sufficient and meterable coolant and pressurising medium in use with organic tissue parts, such as living-cell products, plant and animal foodstuffs.

Title: Method of self-testing a random access memory (RAM) of a circuit
Inventor: CORDELL STEVE DIPL ING
IPC: G11C29/12
Filed: 1988-05-26
Abstract: During operation of a flight-critical or safety-critical circuit, e.g. of an on-board computer, only certain types of error of a RAM can be tested. Since such computers are necessarily of the Neumann type, RAM self-tests by programs take up part of the computer power. The RAM self-test device of the invention uses address and data information which is available to the central processing unit of the computer to generate RAM test area information, so that the RAM self-test device can almost always carry out its RAM tests at the maximum speed of the RAM, and thus carry out the following tests: physical cells which are not adjacent to each other, and maximum speed tests of the read amplifier. The device uses the information listed above to predict whether the cells to be tested will be required for the next cycles or not, and thus whether they will be available for the test.
