Title: Local dose monitoring in nuclear plant surroundings - having compensation of zero effect on scale for increasing background radiation
Inventor: FICKERT WOLFGANG DIPL PHYS
IPC: G21C17/00
Filed: 1974-09-27
Abstract: An activity measuring point for a flowing medium, e.g. gas or air in a nuclear power station, comprises a scintillation counter or counting tube with a given calibration factor K, which can vary slowly (e.g. over months) with changes in background radition. A dose meter integrates the count in a specific period and provides a logarithmic indication on a scale. The beginning of the scale can be adjusted by at least one decade. A pulse generating device is used for supplying a count adjustable through the range 10-3 to 102 impulses per second; this count is subtracted from the count given by the detector, to give a residual zero effect (N1); thus the product of N and K, which determines the scale, can be adapted to the background radiation by setting it to a desired value. Pref. the measuring instrument comprises a decadic scaling-down unit giving infinite adjustment of the start of the scale over two decades. Typically, for monitoring circulating air inside the secondary shield of a nuclear power plant. The scales of a number of different instruments can be easily adjusted from time to as the background reactivity increases.

Patent DE-2449342-A1 (DE)
Title: Tuning circuit for superhet radio receiver - has variometers or rotary capacitors to give exponential tuning function
Inventor: HANSEN JENS DIPL ING
IPC: H03J3/28
Filed: 1974-10-17
Abstract: The tuning circuit, for a superheterodyne radio receiver, uses variometers or rotary capacitors to tune the frequency. The frequencies of the various tuning circuits are altered according to an exponential function. The exponential tuning is achieved by winding the variometers' coils such that their core movement results in an exponential change in frequency. If rotary capacitors are used then their plates are shaped to give the exponential change. The advantage lies in avoiding errors that arise because the curves produced by frequency changes and the tuning device are not identical.

Title: Analyser for toxic gases in flue gases - absorbs gases into liquor, detects gas conc. and controls liquor flow
Inventor: ESSERS KARL-HEINZ ING GRAD
IPC: G01N27/416
Filed: 1974-12-07
Abstract: System for continuous determination of HF or HCl concns. in flue gases using an absorption cell through which a sample stream is passed and also through which a stream of absorbent liquor (esp. water) flows. The HF or HCl concn. in this is measured by a probe and the liquor flow adjusted to keep this constant, using a control signal to a metering pump. This control signal gives a measure of the HF or HCl present in the original gas sample. The cell has an integral probe which leads to a controller, the output from which is split, one way to an indicator the other to the metering pump. The cell has an overflow to maintain a constant vol. of liquid. Esp. for use on exhaust gases from garbage incinerators. Existing methods have numerous disadvantages e.g. conductivity and other probes are liable to several interfering factors. The method described is of simple construction, gives simple linear signal and cross sensitivity is largely excluded.

Title: Motion reversal unit for printer ink ribbon - has powered toothed wheel mounted on arms swivelable to engage with one or other ribbon roller
Inventor: TUERK EUGEN
IPC: B41J17/14
Filed: 1975-06-30
Abstract: The direction of motion of a printing ink ribbon which passes between two rollers (1, 2) can be reversed by a simple gear mechanism mounted on a swivelable pair of arms. Both rollers have toothed drive wheels (3, 4) on their ends. The drive wheel (4) for the take-up roller is engaged with a gear wheel (5) whose axle runs between the elongated arms (6, 7) of a friction coupling. A further gear wheel (8) located between the arms meshes with the lower wheel (5) and has its axle (9) forming that of the motor unit. The two arms are connected by assuring (10). When the motor axle reverses its direction of motion, the arm pair is swivelled about the motor axle by the friction coupling until the lower gear wheel (5) meshes with the drive wheel (e.g. (4) of the roller. Reversing the direction of motion again causes the arm pair to swivel and engage the lower wheel (5) with the other roller drive wheel (e.g. 3).

Title: Call alloting system for telephone exchange - limits forward moves of calls which are held in cyclic waiting registers
Inventor: OTT GERHARD DIPL ING
IPC: H04M3/523
Filed: 1975-07-30
Abstract: The call allotting and stacking system, for a telephone exchange, allots calls by considering priority and waiting time. Incoming calls are assigned a priority and are held in call and waiting registers in the order in which they arrive. They are read out of the registers in the same order as they were written in. The object of the invention is to limit the number of 'forward moves' in the cyclic waiting register and not to initiate such a forward move for all complete calls but only for some. This is achieved by making the forward move of a call waiting in the call register conditionally dependent on a new incoming call's finding no room in the call registers.
