Patent DE-3427010-A1 (DE)
Title: Method for detecting and evaluating acoustic detonation signals, and an arrangement for carrying out the method
Inventor: SCHUHMACHER ALBERT DIPL PHYS
IPC: G01H3/12
Filed: 1984-07-21
Abstract: In order to detect and evaluate acoustic detonation signals which are subject to interference and occur when a round leaves the barrel mouth or strikes a target, the interference signal which occurs at the same time is subjected to formation of an average value by means of an average-value forming device, especially a median-value forming device. The median of the amplitude values occurring within a time interval  DELTA  tau  corresponds to the interference signal level existing in the received signal and is used for calculating an adaptive threshold. If this threshold is exceeded by the detonation signal which is subject to interference, for a predetermined time interval  DELTA tau , then this received signal is interpreted as the real detonation signal. Detection of the length of the detonation signal allows the analysis interval to be shortened without loss of information. Furthermore, received detonation signals which occur shortly after one another in time can still be resolved and evaluated.

Title: Method and device for error detection in measuring devices
Inventor: HUBER MARTIN DIPL ING
IPC: G01D5/244
Filed: 1985-03-18
Abstract: In such a measuring device, in order to measure the relative position of two objects the periodic scanning signals (S1, S2) obtained during scanning of the grid division (la) of a grid scale (1) by means of the grid divisions (2a, 2b) of a grid scanning plate (2) are fed to an evaluation device (W) for determining the measured values for the relative position of the two objects. At the same time, the two periodic scanning signals (S1, S2) are supplied to an error detection device (F) which transmits an error signal in the event of defective signal parameters of the two scanning signals (S1, S2). The amplitude levels of the two scanning signals (S1, S2) are each checked on both sides of their zero line in the error detection device (F) for an upper limiting value and for a lower limiting value, this checking being performed periodically in an alternating fashion. In the error-free state, the error detection device (F) supplies a periodic detection signal (ES), and in the defective state an aperiodic detection signal (Figure 1). <IMAGE>
Patent DE-3515505-A1 (DE)
Title: Moulding plant
Inventor: FISCHER KURT
IPC: B22C15/00
Filed: 1985-04-30
Abstract: The invention proposes a moulding plant for the production of foundry moulds, in which the load-bearing supporting elements are designed in such a way that the centre of gravity of the plant lies in the region of the mould combination. This proposal is achieved by means of shorter supporting columns and by the fact that the final crossmember is not arranged above the pressure chamber or filling container but is moved essentially into the plane of the bottom opening of the filling container. This arrangement ensures that the plant can be converted at any time and without great expense to taller or larger pressure vessels. There is no upper limit to the overall height in relation to the moulding machine. In addition, there is a not inconsiderable weight saving as regards the material and this has a positive effect on the overall price. The vibrational effects in the surroundings are furthermore reduced.

Title: Variable connecting pieces for handle spars with different mitring on the rig for a sailboard
Inventor: BLECH SIEGFRIED
IPC: B63B35/79
Filed: 1985-06-05
Abstract: The connecting pieces of the handle spars of a wishbone of a known type of construction are designed in such a way that end pieces with different mitre angles are required for wishbones of different shapes. For the multiplicity of shapes about eight different end-piece fittings are required. A producer therefore requires sixteen tools in order to be able to manufacture eight end-piece fittings. The situation is similar for the user. Most surfers use three to four sails, the profiles of which are very different and therefore wishbones bulged to different degrees have to be used. The object of the invention is therefore to save substantial costs for the producer. This is achieved in the case of the subject according to the invention by the two ends of the two U-shaped end pieces being designed to be movable. The four movable ends now available enable the producer to build all desirable wishbone shapes with one end-piece fitting. It follows from this that the producer only needs two tools instead of sixteen. With a wishbone end-piece fitting movable at the ends, the user could combine from any number of handle-spar fittings a corresponding number of wishbones.

Patent DE-3543432-A1 (DE)
Inventor: KUNZ PETER DIPL ING
IPC: C02F3/00
Filed: 1985-12-09
Abstract: To purify waste water a process is proposed in which, in addition to physical pre-clarification (5) with the formation of a biological primary sludge, a biological pre-treatment (8) is envisaged in which conversion of the material is controlled in order to adjust the loading in the following treatment stages. The sludge accruing in the biological pre-treatment is separated by filters (23) from the waste water and fed to the primary sludge. As a result of the biological pre-treatment, suspended inorganic and organic matter is removed from the waste water, as well as easily convertible and dissolved organic compounds, so that they do not overload the subsequent processing stages. By controlling the conversion of material it is possible to vary in a specific manner the loading of the subsquent processing stages, for example to hold it constant irrespective of the inflow conditions in the pre-clarification stage. If a biological post-treatment is effected, it is possible to adjust the balance of nutrients in the post-clarification stage by controlling the conversion of material in the pre-clarification stage.
