Title: Connection circuit for individual audio frequency sources with a free choice of amplifier
Inventor: KRUEMMEL WOLFGANG
IPC: H04B1/20
Filed: 1981-10-01
Abstract: The invention is for the field of entertainment electronics. The technical problem lies in that, although connections of individual audio frequency sources can be established, it is necessary to have headphones or additional connection lines for monitoring during copying in the case of two audio frequency sources not connected to the amplifier. Using this invention, a central location is selected for connecting the individual audio frequency sources, with free choice of the amplifier. The solution lies in that everything is hard-wired, interconnected and interlocked with respect to one another in the connecting circuit as can be seen from the attached drawing. The amplifier is also still freely selectable, that is to say the audio tape recorder or the cassette recorder or the broadcast receiver (radio) or the record player can be connected to the "amplifier" socket. It is now possible to allow the other devices to play via the amplifier by operating the correct switch for this, from S8 to S11. It is also possible to use an amplifier instead of the audio frequency sources listed above. <IMAGE>

Title: Arrangement for discharging chips into an elongated chip bunker during the course of production of chipboards and the like
IPC: B65G69/04
Filed: 1981-10-29
Abstract: The invention relates to an arrangement for discharging chips, mixed in a gluing station with a thermosetting binder, into an elongated chip bunker during the course of production of chipboards and the like. Belonging to the basic construction of the arrangement are a feed pipe, a conveying screw arrangement and a discharge head. The conveying screw arrangement comprises an upper conveying screw, connected to the feed pipe, and a lower conveying screw, equipped with the discharge head. The two conveying screws are connected to each other via a downpipe by a swivel joint. The discharge head can be moved periodically in the longitudinal direction of the chip bunker as well as transversely thereto. The upper conveying screw is pivotally mounted about a vertical axis by its end assigned to the feed pipe. The lower conveying screw is arranged parallel to the longitudinal axis of the chip bunker and can be moved periodically as a whole transversely to the longitudinal axis over the region of the two bunker side walls. The upper conveying screw is not only mounted pivotally, as described, but also displaceably in the longitudinal direction, by its end assigned to the feed pipe. The discharge head can be displaced back and forth in the casing of the lower conveying screw. It is achieved in this way that no chip separations occur in the region of the bunker walls and also a uniform filling of the outer zones takes place. <IMAGE>

Patent DE-3232802-A1 (DE)
Inventor: WALZ ALFRED PROF DR ING
IPC: H05B41/232
Filed: 1982-09-03
Abstract: Ultraviolet radiation is the wavelength range between 150 and 300 nanometers, which both generates ozone (O3) and has a germicidal effect both in ambient air and in a pure oxygen atmosphere, is performed in a highly energy-efficient manner, by utilizing a low-voltage, low-pressure gas discharge lamp, by using a radiation-transparent quartz tube, by equipping it with a long-lasting sintered electrode pair and filling it with a mixture of gas vapor and mercury vapor, by disposing a circuit device between the mains and the gas discharge tube which rectifies the mains alternating current and effects smoothing voltage multiplication, and by coupling this circuit device with an automatic, dry-switching commutator device for the direct current of the gas discharge lamp, in order in principle to avoid a mercury-vapor dissociation (cataphoresis) which would reduce the effectiveness of the radiation. As a result of the direct current operation, the energy efficiency of the UV radiation generator is improved by up to 30%, as compared with direct operation of the gas discharge lamp with alternating current and a standard alternating current choke, because of the reduction in heat losses both in the gas discharge process and in the voltage multiplier choke.

Title: Exhaust steam pipe system in steam power plants having bypass stations
Inventor: HEEREN HERMANN
IPC: F28B9/02
Filed: 1982-09-30
Abstract: The aim in an exhaust steam pipe system in steam power plants having bypass stations, there being provided - per exhaust steam line - two pipe bends having deflecting devices and a straight connecting pipe between the pipe bends, is to create a feeder device for bypass steam which requires relatively little space, and allows as high as possible a blow-in rate and the retention of the deflecting devices designed for normal turbine operation. According to the invention, this is achieved when there are provided at the or at each connecting pipe near the deflecting grid, which is located upstream, one or more feed lines which feed the bypass steam tangentially and obliquely into an interior bounded by a wear-resistant material in the region of the feed-in point or points.
Patent DE-3237146-A1 (DE)
Title: Metal-encapsulated high-voltage switching device
Inventor: PLESSL ANDREAS DR
IPC: H01H31/32
Filed: 1982-10-07
Abstract: In the metal-encapsulated high-voltage switching device having two field electrodes (1, 2) which bound a separating path between two potentials in the switched-off position, and a moving contact pin (3), which passes through the separating path in switched-on position, the field electrode (1) which coaxially surrounds said contact pin can move together therewith into an intermediate position. In this case, the guidance of the contact pin (3) and the field electrode (1) is constructed such that during their joint movement between the switched-off position and the intermediate position, the contact pin (3) in each case projects slightly beyond the field electrode (1) into the separating path. As a result of this measure, a spark which ignites when switching the high-voltage switching device under voltage will always start on the tip of the contact pin and not on the field electrode (1), which can hence be guided very close to the opposite field electrode (2). The immediate vicinity of the field electrode (1) with respect to the spark centres the latter on the one hand heavily onto the axis of the separating path and, on the other hand, reduces the electrical field strength at the spark in an optimum manner so that flashovers to earth can be prevented at source. <IMAGE>
Patent DE-3238793-A1 (DE)
Inventor: ARTMANN JOACHIM DIPL PHYS DR
IPC: B03C3/14
Filed: 1982-10-20
Abstract: Gas scrubbing method and device enabling an agglomeration of particles to be separated (12) owing to the application of an electric field (E). It is particularly easy to separate the agglomerates (23) because of their mass and size in mechanical separators, for example in a simple cyclone (22). Such method is perfectly appropriate to the scrubbing of fossil fuel exhaust gas but it also enables the separation in the same way of droplets, for example water vapor, from a carrier gas. The intensity of the electric field is lower than the intensity of the ionisation field so that the unit operates hardly with any electric power consumption.

Title: Method and measuring instrument for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground
Inventor: HUEBNER HANS-JOERG DIPL KFM
IPC: G01N33/00
Filed: 1982-11-25
Abstract: In a method for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground, in which a measuring instrument is used for measuring the respective characteristic quantity, the measurement value, after the characteristic quantity has been measured, is normalised in accordance with a predeterminable normalisation function to one or several parameters in the measuring instrument - triggered manually or automatically, and thereafter the normalised and possibly also the absolute measurement value is displayed and stored, a normalisation function which can be handled mathematically in the simplest possible way and requires only little storage space can be used under all circumstances in that a progression approximating the normalising function is calculated and is used as normalising function. If the characteristic quantity is measured with a measuring error which is greater than the mathematical error occurring during the calculation of the normalisation function, the number and/or the width of the progression sections of the progression are to be predetermined on the basis of the magnitude of the measurement error so that the approximation of the progression of the normalising function is not unnecessarily accurate which would lead to increased storage space requirement.
