Abstract: To enable small or medium-size containers to be directly secured to locking members existing on vehicle loading areas for ISO containers and to be placed in ISO containers or ISO container frames, only one (23) of two fittings (23, 27) provided at opposite container ends is rigidly mounted whereas the other (27) is foldable between an operative position in which it projects beyond the outer dimension of the container, and a rest position in which it is inside the outer container dimension.

Abstract: A distributed antenna system for wireless communication inside enclosed areas such as buildings, tunnels, etc., includes an antenna cable and a termination circuit which provides a plurality of termination impedances for the cable, varying as a function of time. The termination circuit may include a diode coupled to the cable at a remote end of the cable and a bias voltage generator coupled to a local end of the cable. Changes in bias voltage alternately forward biases and reverse biases the diode, effectively changing the termination impedance of the antenna cable. As the impedance changes, nodes and regions of high multipath distortion move, so the probability is greatly increased that personnel with remote communication equipment will be able to send and receive good quality signals over the antenna cable at any given location.

Abstract: A call progress circuit for both a customer owned, coin operated telephone and a regulated telephone is provided that does not mute the paystation's transmitter, so that voice signals from the calling party may be heard by the called party, thereby preventing an answering party from hanging up prematurely. The call progress circuit employs a transmitter-sourced audio signal discriminator which monitors audio signals placed on the line from the called station, the calling paystation and a central office, and controllably removes or subtracts out those audio signals that originate at the paystation transmitter. The discriminator includes a pair of tunable bandpass filters respectively associated with a telephone line receiver and the paystation transmitter circuit. Coupled to these filters is an audio spectrum scanner which sequentially adjusts the sensitivity characteristics of the filters.

Abstract: A device works according to the displacement principle, i.e., at least two displacers are provided in a common displacer working chamber or in displacer working chambers communicating with one another, and are drivingly coupled together by a pressure transmission medium. Elastomer material is disposed as the pressure transmission medium, at least in the region of one displacer.

Abstract: A supporting mount for the angularly mobile flexible support of a supporting member of a wheel suspension, especially a shock absorber, has a mount core which is vulcanized into an elastomer body and the movements of which are limited in the supporting direction by stops fixed in relation to the housing. The elastomer body is prestressed in the mount housing in the supporting direction and held in a manner which does not involve contact with the stops. The supporting mount makes it possible to introduce small supporting forces comfortably into the vehicle bodywork by a soft characteristic while larger supporting forces are transmitted by the stops via a progressively hardening characteristic.

Abstract: An arrangement for limiting the terminal voltage in an alternator has a fixed stator winding acting on rectifiers and an excitation winding which rotates with the alternator rotor. The arrangement also has a controller and a first slip ring contact which load the excitation winding with excitation current as a function of the magnitude of a delivered voltage, and at least one free-wheeling valve which is conductive during a controller-side interruption of the excitation current and is connected in parallel with the excitation winding. The arrangement includes an auxiliary winding on the rotor. The auxiliary winding continues the excitation winding in the same direction of winding, with the auxiliary winding and the excitation winding being connected at a first connection point. A second slip ring contact operatively connects the first connection point to a machine terminal supplying excitation current.

Abstract: A process for determining the state of a battery by carrying out in a cycle, starting from a specific charging state of the battery, a charging operation and a discharging operation, each with a specific current, the cycle being terminated when the specific charging state is reached again, and the state of the battery being deduced from the difference between the time periods required for the charging operation and the discharging operation. Alternatively, from a specific charging state of the battery a discharge can be carried out, in order to determine the available capacity from the extracted charge.

Abstract: A propelling nozzle has upper and lower primary and secondary flaps which are disposed opposite one another at a mutual distance and which are sealingly movably guided between lateral wall portions of a four-cornered nozzle housing. The primary flaps are arranged pivotally about a fixed axis of rotation on the nozzle housing. The secondary flaps, in each case upstream of levers non-rotatably connected with the primary flaps, are pivotally linked to pivots situated on the side facing away from the nozzle flow. The secondary flaps change into the primary flaps with a surface section which is bent concentrically with respect to the pivots. The primary and secondary flaps are arranged in a four-cornered nozzle housing which is itself closed in. In each case the secondary flaps are arranged on the nozzle housing in an axially movable and angularly adjustable manner at the downstream end. The levers are formed on interior sections which are bent away from the primary flaps in a toggle-lever-type manner.

Abstract: A controllable semiconductor switching device having integrated overload protection of a load current path, including a switching section in the load current path and a multiplicity of main switching cells acting in parallel and having load-side terminals and non-load-side terminals including control terminals. The control terminals of the main switching cells are directly connected in a highly conducting manner among one another. A multiplicity of auxiliary switching cells are provided which carry a part of a total load current in parallel with the main switching cells in order to achieve an overload protection, and having load-side terminals and non-load-side terminals. The number of auxiliary switching cells are less than the number of main switching cells. The main switching cells and the auxiliary switching cells form the switching section.

Abstract: A Qualitative Reasoning System (QRS) performs machine failure isolation by generating a plurality of pending hypotheses which assume the failure of one or more machine components and by testing each of the hypotheses by propagating actual values for machine parameters through confluence equations for the hypothosis being tested. Hypotheses which produce an inconsistent set of predictions are discarded while hypotheses which produce a consistent set of predictions are saved. The hypotheses are generated using a model instance data element which contains a qualitative physics model description of the machine. The machine failure is isolated when all but one hypothesis, which assumes the failure of one or more elementary machine components, remains.

Abstract: In the case of a feeding and opening device for an open-end spinning arrangement having a tuft support, which follows a feeding table, it is provided that the tuft support is arranged stationarily and has a guiding surface which is situated opposite a feeding roller, extends approximately radially with respect to the opening roller and continues the clamping surface of the feeding table.

Abstract: In conventional processes of electron beam measuring, the measurement of signals at a measuring point of a sample occurs following scanning and averaging procedures with the aid of potential contrasts. For this purpose, the point of measurement is impinged upon with a short primary electron pulse, which is released by a trigger pulse, which is synchronous to the signal to be measured. The average value of the secondary electron pulse stream resulting from very many primary electrons is measured and is a measure for the signal at the measuring position at the point in time of the impingement of the primary electrons. The generation of primary electron pulses occurs with a beam modulation system. As the primary electron pulses are generated in response to the trigger pulses, this system has to be designed very widebanded.

Abstract: In the case of a drafting unit for a spinning machine comprising several top rollers and bottom rollers, continuous cleaning belts are provided which are arranged and held in such a manner that, because of the inherent weight of at least one of the deflecting rollers, they are tensioned, on the one hand, and, on the other hand, are brought to rest against the top rollers or bottom rollers.

Abstract: Aerodynamic window for a gas laser, whose active chamber emits a focussed ser beam and is flow connected by means of a beam passage opening with a window chamber connected to a vacuum pump and which has a beam exit opening in an outer area which is preferably under atmospheric pressure. In order to reduce the pumping power necessary for the aerodynamic window and improve the laser beam quality, the window is so constructed that the laser beam emitted by the active chamber has a first focus in the vicinity of the beam passage opening and is deflected onto a focussing mirror arranged in the window chamber and which gives the laser beam leaving the latter a second focus located in the vicinity of the beam exit opening.

Abstract: In the case of a tangential-belt drive for an open-end spinning machine, having a tangential belt driving the spinning rotors of several spinning units arranged behind one another, it is provided that the spinning units each comprise a pressure roller loading the tangential belt and a rotor brake which can be jointly actuated by means of a common actuating mechanism. In addition, an actuating possibility is provided by means of which the pressure roller, for increasing the pressure force, can be increasingly pressed against the tangential belt during the run-up.

Abstract: An alkaline nickel-cadmium storage battery in which the active material with which the negative electrode is filled with, or the electrolyte in the storage battery, contains polyvinylpyrrolidone as an expander. Polyvinylpyrrolidone compounds having a mean molecular weight of 5,000 to 35,000 g/mol have proved particularly advantageous.

Abstract: A sweeping machine having a housing which comprises two housing parts that can be separated from one another. One housing part is used for the bearing of two circular brooms. The other housing part is constructed as a receptacle for sweepings. An arrangement is provided for detachably connecting the two housing parts which has devices for the centering and devices for the locking of the two housing parts. The connecting of the two housing parts requires relatively high expenditures in the state of the art. The two housing parts are lifted manually, are hung into one another and are pressed together. They are then locked in this pressed-together position by means of a locking lever.

Abstract: A hydraulic damper is designed, for example, as a piston/cylinder unit. The arrangement has a part (for example, a piston) forming a vibrational system by means of a spring. Vibrations acting on the damper arrangement are greatly attenuated virtually only in the resonant range of this vibrational system, because only in this case can vibrations of high amplitude be excited and a high dissipation of energy by way of hydraulic flows in channels and between cylinder chambers take place.

Abstract: An edge connector is formed along a sidewall edge of a relatively thin semiconductor wafer. The wafer contains a signal processing circuit to which the edge connector is to be electrically joined. For this purpose a region of material capable of being bonded with conductive material is formed in the wafer and a trench pattern is formed in a first surface of the wafer, so as to expose a sidewall portion of the doped region. The doped region is connected to signal processing circuitry within the wafer. A metallic layer is then electroplated onto the exposed sidewall portion of the doped region. A layer of polishing resistant material, such as silicon nitride, is formed in the trench and the wafer is inverted and wax-mounted face down on a support member such that the first surface of the wafer faces the support member. The wafer is then polished as to effect a thinning of the wafer down to a level which exposes the polishing resistant material in the trench pattern.
