Abstract: The invention relates to a device for protecting objects against ammunition in the form of guided missiles, said device comprising warning sensors (1) for detecting an approaching missile and active elements (2, 3a) for repelling the missile. The sensors (1) and the active elements (2, 3a) are arranged on a common appliance carrier (5) which can be arranged or mounted on the object to be protected. Preferably, a plurality of sensors (1) are arranged on the appliance carrier (5), and firing devices (3a) which can be at least upwardly oriented and are used to fire active elements are arranged in the region beneath the warning sensors. A unit (2) of electronic/electro-optical active elements can be arranged on the appliance carrier (5) in the region above the warning sensors (1) in such a way that it can at least be oriented in an azimuth direction angle.

Abstract: An armored tank is provided and has a weapons station disposed on the roof of a vehicle housing that is carried by a tracked drive. The interior of the housing is divided into three regions, namely a front region, in which are disposed the drive mechanism and the driver's seat, a rear region in which are disposed seats for the crew, and a middle region that is usable for various purposes depending upon the layout of the tank, especially for accommodating a turret platform and/or at least one seat for operators of the weapons station and/or storage space for munitions and munitions delivery mechanisms.

Abstract: The problem addressed by the invention, to develop a microphone with assoted amplifier which has a better dynamic response than analog microphones, requires less space, can replace analog microphones by using cables already in place, and has a low-cost construction, is solved by the invention in that the microphone is made up of an electroacoustic transducer, two analog-digital converters, two preamplifiers connected to the output of the electroacoustic transducers on the one hand and on the other hand each with preamplifiers connected each to an analog-digital converter, and with a driver stage connected to the analog-digital converters for a two-channel digital audio format and in that the amplifier is made up of a receiver for a two-channel digital audio format and a signal processor which generates a one-channel signal from the two-channel audio format as an image of the signal of the electroacoustic transducer. The field of application is in musical production. The invention is illustrated by FIGS.

Abstract: System for analog-digital conversion of signal using at least two less highly resolving AD converters, each having a different preamplification, wherein the AD converter having the most favorable resolution of the momentary signal is utilized to compute therefrom the digital output signal of the system. The preamplifications do not have to be precisely known, but are determined by means of the digital signals formed by the conversion. Preamplification errors, such as offset errors or transmit time errors, are eliminated by choosing the appropriate computation algorithm.

Abstract: This invention relates to a circuit for converting an analog audio signal to a highly resolving bit stream. An audio signal (U.sub.In) is converted on several parallel paths (1, 2) having different amplitude sensitivities into a data stream, where the offset of the individual paths (1, 2) is compensated for individually. Subsequently the amplification difference produced by the different amplitude sensitivities is determined and compensated for, so that one of the two data streams is made available as a bit stream for further processing. The selection of the data stream which is made available as a bit stream for further processing, is determined based on the amplitude of the audio signal (U.sub.In).

Abstract: A coupling member for transmission of shock waves from a shock wave device to a patient to be treated is composed of an elastic, shape-stable material having a moist outside surface, and is preferably formed of a hydro-gel, such as a polyacrylamide gel. The material is provided with an insert which contributes to its good stability and also enables manipulation of the member. The coupling member can also include, with or without the insert, a shock wave sensor which is embedded in the material and enables checking the power and the position or center of the shock wave source relative to a predetermined point.

Abstract: Gelatin capsules, consisting of a capsule sheath and a capsule filling, the capsule sheath consisting of gelatin, optionally a plasticizer and further additives, and the capsule filling containing active substances and/or dietectic agents and, optionally, further additives and a liquid or powder, in the capsule sheath additionally contain an additive of at least 1% by weight of an agent which in the pure state is capable of absorbing water in an amount of at least 10% by weight of its own weight without undergoing a change in its appearance.

Abstract: The deformability measurement chamber is subdivided by a foil into two chamber spaces. The foil has a passage opening, the diameter of which is smaller than the diameter, at rest, of a red blood corpuscle. A static pressure gradient exists between the two chamber spaces, so that a flow takes place from one chamber space to the other. In the region of the passage opening there is situated on each side of the foil an electrode, which is connected to an alternating voltage source. In order to achieve a measurement signal which is approximately one order of magnitude greater, at a given alternating voltage frequency, a current-measuring operational amplifier is disposed in the connecton of one electrode to the voltage source.

Abstract: A device for detaching a sheet-shaped copy support from a moving photoconductive layer by fluid pressure. The device includes a nozzle arrangement which directs pressurized fluid, such as compressed air, toward a sheet of copy paper or other copy support. The action of the fluid on the copy support creates a suction pressure which draws the copy support toward the nozzle arrangement to detach the copy support from the photoconductive layer. When the copy support has moved into close proximity and generally overlying relationship with respect to the nozzle arrangement, the fluid is passed off generally tangentially with respect to the copy support to maintain a constant suction and to avoid undesirable oscillations of the copy support. This, in turn, eliminates the undesirable noise associated with such oscillations.
