Patent DE-3235385-A1 (DE)
Title: Optical reader with light pen
Inventor: MOORTGAT-PICK WALDEMAR DR
IPC: G06K7/10
Filed: 1982-09-24
Abstract: Known embodiments of optical readers with a hand-guided light pen for scanning alphanumeric or bar-coded printed or written characters are generally used in connection with devices for acknowledging and checking the data read in in the form of displays. In the arrangement proposed here, the light pen is mechanically connected to a coloured marking pen in such a manner that the written or printed characters scanned during the scanning process are given a coloured background and in this manner the reading-in of the information items is confirmed. Time-consuming checks in detail can thus be omitted within certain limits of the required protection against errors. Developments of the proposal relate to constructional details of the arrangement and holder for the sensor area of the light pen and of the marking pen with the aim of high protection against errors during the scanning. Further measures relate to the quality and type of colour of the marking pen and the influence on the contrast of the goods to be read. Furthermore, simple constructional proposals are made in order to enable the coloured marking of certain parts of the goods to be read to be optionally omitted in rapid change.
Patent DE-3238717-A1 (DE)
Title: Unbalance vibrator
Inventor: PETER ROLF DIPL ING
IPC: B06B1/16
Filed: 1982-10-19
Abstract: To obtain an optimum oscillation emission for the vibration of a mixed concrete mass to be shaped, the centre of gravity of the unbalance flywheel has to be selected according to the particular state of this mixed concrete mass or always adjusted for this purpose. So that the work cycle does not always have to be interrupted again for this, there is an unbalance flywheel consisting of two parts 5, 6. These are provided in an unshiftable rotatably mounted drive shaft 2 so as to be rotatable together with this and be radially displaceable relative to one another therein. At the same time, at their free ends 12 they are supported in a spring-prestressed manner on the inside 14 of a displaceable limiting ring 7. By adjustment means which can act on the limiting ring 7 from outside, the adjusting ring and with it the unbalance flywheel parts 5, 6 can now be displaced relative to the fixed rotatable drive shaft 2 even during the rotation of the latter. The centre of gravity S1 of the unbalance flywheel 5, 6 can thereby be adjusted continuously relative to the centre of gravity S2 of the drive shaft 2 from a neutral position (S1 and S2 coincide) within the possible adjustment travel X up to a maximum unbalanced position (S1 and S2 have been shifted as far as possible apart from one another). <IMAGE>

Title: Circuit arrangement for generating axle counting pulses for axle counting systems
Inventor: BAUER FRANZ-LOTHAR ING GRAD
IPC: B61L1/16
Filed: 1983-01-28
Abstract: In order to generate axle counting pulses in axle counting systems, a track device is used having two AC-fed transmitting circuits (SS1, SS2) and receiving circuits (ES1, ES2) assigned thereto. The useful reception voltage of the respective receiving circuit (ES1 and ES2, respectively) is modulated when a vehicle wheel passes by. The level change of two transmitting and receiving circuits arranged one next to the other in the direction of travel is evaluated to form axle counting pulses which are dependent on the direction of travel. For each receiving circuit (ES1, ES2), a bandwidth is provided which is at least as large as the maximum repetition frequency of a steeply edged interference voltage. Between the respective receiving circuit (ES1 and ES2) and a device (Z) which evaluates the useful reception voltage of the receiving circuit a temperature compensation element (TK1 and TK2, respectively) and a bandpass filter (BP1 and BP2, respectively) are connected. The bandwidth of this band pass filter has larger dimensions than given by double the repetition frequency of the axle counting pulses. In addition, the bandwidth of this band pass filter (BP1 and BP2, respectively) is smaller than the bandwidth of the associated receiving circuit (ES1 and ES2, respectively). By means of these measures, undesired interference signals are largely suppressed. <IMAGE>

Title: Ship for scooping up oil
Inventor: WAAS HEINRICH DR ING
IPC: B63B35/32
Filed: 1983-08-01
Abstract: The invention relates to a ship for scooping up oil floating on the sea, which ship moves abeam when in service and as a result impounds a carpet of oil and scoops up this oil through slots in the side wall of the ship. Since such a ship moving abeam will possibly roll to a considerable extent in a swell, the two ends of the ship are to be connected according to the invention to the midship section by one joint each in such a way that they can be swung through 90 DEG  from the longitudinal axis of the ship during service. The rolling is thereby reduced and the capacity of the ship to scoop up oil is improved.
Patent DE-3332449-A1 (DE)
Title: Electrostatic spray process and rotary atomiser
Inventor: PETRICK PAUL DR
IPC: B05B5/04
Filed: 1983-09-08
Abstract: The apparatus is for electrostatically assisted spraying of an electrically conductive liquid, especially an aqueous plant protection liquid. So that the liquid supply container and the liquid feed system can be at earth potential in spite of electrical charging of the sprayed liquid, the liquid is fed to the atomiser disc, which consists of electrically insulating material, at its axial centre and at earth potential and is only brought to a high voltage once at the spraying edge of the atomiser disc, by means of a contact electrode. The liquid to be sprayed is spread out into such a thin film, by a high rpm of the atomiser disc, that because of the very small cross-section of the liquid film, its electrical resistance value between the spraying edge of the atomiser disc and the feed point of the liquid bridges over the potential difference between the high voltage potential and the earth potential with a loss current of at most 2 mA.

Title: Arrangement for stabilising the frequency of a pulsed IMPATT oscillator
Inventor: WIPPICH HEINZ-GEORG DIPL ING
IPC: G01S7/282
Filed: 1984-03-20
Abstract: This oscillator is used as transmitting oscillator in a transmitting/receiving device, particularly in a radar sensor, in which received signals are mixed down to an intermediate frequency by means of the frequency-stabilised signal of a local oscillator in a receiving mixer. The transmitting signal generated by the IMPATT oscillator (Imp. Osz.) partly crosses over into the receiver circuit where an IF signal is generated at the output of the receiving mixer (Mischer). The IF signal is conducted via a low-noise preamplifier, on the one hand to a high-pass filter and on the other hand to a low-pass filter. The passband characteristic of high-pass and low-pass filter is selected in such a manner that it in each case covers the top and bottom boundary area of the IF band width. A pulse-shaped control signal present at the output of one of the two filters (high-pass filter, low-pass filter) when the actual IF frequency is too high or too low is supplied to a controller which corrects the basic setting of a modulator (Imp.-Mod.) allocated to the IMPATT oscillator (Imp. Osz.). <IMAGE>
