Abstract: The filter comprises two high pass units (8,9) and one low pass (10), coupled in series. The one high pass filter (8) has a damping which decreases at the rate of 24 dB/octave to a break point of 300 Mz. The damping in t-e other such filter (9) reduces at the rate of 6 dB/octave to a break point of 1600 Hz. The low pass filter (10) damping increases at the rate of 12 dB/octave from a break point of 3400 Hz. Interference noise in a vehicle comprises, inter alia, engine noise, bodywork noise, tyre noise, and to a certain extent that from fans or from wind drag. Such noise is dominated by a low frequency level, the strength of which decreases at frequencies up to some thousand Hz, after which it is constant, or re-increases somewhat. Damping in the frequency band 300-3400 Hz decreases in the same way as the expected strength of interference noise occurring in the vehicle decreases pro rata to the increase in frequency.

Abstract: In a top part for a sanitary shut-off valve which, within a housing, comprises a fixed control disc and a control disc which can be rotated relative to the first control disc, the valve spindle is connected in terms of its drive to a motion brake. In this way, excessively fast turning of the rotatable control disc into the closed position, which could give rise to water hammer in the connected pipes, is prevented. The motion brake comprises a piston which moves backwards and forwards in an essentially closed space and divides this space into two subspaces. The subspaces are connected to one another via a displacement path. A viscous fluid medium fills the two subspaces of the essentially closed space and, when the piston moves, is forced backwards and forwards between these spaces. The motion brake can be designed as a lubricant pump which brings about forced lubrication in the gap between the two control discs. <IMAGE>

Abstract: An ion plasma electron gun for the generation of large area electron beams with uniform electron distribution. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid into a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid and the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and a uniform electron distribution which is substantially the same as the ion distribution of the ion beam impinging upon the cathode. Control of the generated electron beam is achieved by applying a control voltage between the wire and the grounded housing of the plasma chamber to control the density of positive ions bombarding the cathode.

Abstract: Overload protection device for torque measuring transducers comprising a measuring axle (1) intended for a certain maximum measurement range. According to the invention the device is surrounded by a housing (3) which is preferably journalled riding on the measuring axle, but being prevented from rotating by means of a link to a fixed point. A certain length of the measuring axle in the housing is used as measuring distance and at either end thereof a larger gear wheel (4,5) is attached free of backlash. These gear wheels are in engagement, with a well-defined backlash, with respective smaller gear wheels (6,7) which are each fixed to one end of a second axle (2) journalled in the housing. When applying a torque on the measuring axle which with a certain margin exceeds said measurement range, the twist of the measuring axle between the larger gear wheels will arrive at such a value that the backlash between the teeth is eliminated, thus causing the takeover of overload by the second axle 2. The input torque on the measuring axle is geared down to the second axle, which is therefore insignificantly twisted upon additional overload, thus effectively protecting the measuring axle against excess overload.

Abstract: The innovation concerns a construction of an instrument for analysis of trace elements in samples with a dimension in the size of mm with the use of X-ray-induced X-ray-fluorescence. The instrument consists of a microbeam of monochromatic X-rays and an X-ray detector (10) for detecting the fluorescent radiation from the sample (9). As X-ray source an X-ray tube (1) is used with a line focus (2) and the radiation is guided out to the sample by a capillary (3). By utilizing the total reflexion of X-rays which can take place inside the capillary (3), high intensity as well as an efficient suppression of high energy X-rays as compared with low energy X-rays, can be achieved. At the same time, by utilizing the selective absorption which occur for low ''take off'' angles (the angle between the capillary and the anode plane), the radiation both below (lower energy) and above (higher energy) the characteristic radiation from the anode can be effectively suppressed.

Abstract: A digital wireless subscriber telephone unit for wireless connection with a base station. The subscriber unit has a baseband processor which is coupled to storage device for the baseband functions. The baseband processor is direct access coupled to a modem processor whereby the two processors may communicate with each other. The modem processor generally acts as the master in the system, although lock-out circuit may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified. The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal. On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode. In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with a looped-back signal to produce correction constants to compensate for undesirable variations in the IF, these constants being stored for use in correcting actual received signals. During demodulation, the modulated digital signals are fed to the modem processor in the form of time multiplexed I and Q samples and are demultiplexed. The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.
