Patent DE-3133269-A1 (DE)
Title: Seed monitoring device
Inventor: STEFFEN DAVID EUGENE
IPC: G01V8/20
Filed: 1981-08-22
Abstract: The subject-matter of the invention is a seed monitoring device for a sowing machine with a seed sensor which consists of a housing forming a tubular line and a light source attached thereto and three light-sensitive elements arranged as a triangle. The light source and the triangular photosensor arrangement are arranged in such a manner that a seed grain passing through the tubular line interrupts the light incident on the photosensor arranged at the tip of the triangle before it intersects the light beam incident on one of the two phototransistors forming the base of the triangle. The monitoring circuit contains two signal paths in which different counting methods are used so that different numbers of pulses are generated from the signals output by the three photosensors. One or the other of the two signal paths is automatically selected in dependence on the seed density detected. One of the signal paths contains a delay circuit connected into the connection to the phototransistor arranged at the tip of the triangle whilst the other one contains a single-pulse circuit or monostable multivibrator which is also connected into the connection to the phototransistor arranged at the tip of the sensor triangle. Additionally, a focusing detector generates a particular number of additional pulses or of additional counting pulses for seed grains detected simultaneously or almost simultaneously by the photosensors arranged at the base of the triangle.

Title: Device for controlling the clearing and shunting unit in the entry section of a train-formation track
Inventor: LANG MARTIN DIPL ING
IPC: B61L17/00
Filed: 1981-09-21
Abstract: In train-formation tracks equipped with clearing and waggon-hauling devices there is provision for cleared and shunting units which are moving forward to be reordered chronologically in such a way that the traction force of the drive is, in a borderline case, just sufficient for a clearing and shunting unit in order to transport onwards the compartments which have entered the entry section of the respective track-formation track since the last clearing operation. This is achieved by logically connecting the humping sequences, indicated in the humping memory of the shunting system, for the individual track-formation tracks with the lengths and weights and the running properties of the compartments which are being humped. By utilising the maximum traction force of the clearing and shunting units, longer transport times are available for the individual clearing operations than in the past; at the same time, it continues to be ensured that the entry sections are actually cleared even in the case of an unfavourable humping sequence. <IMAGE>

Title: Method and device for manufacturing moulded confectionery products
Inventor: MEINERS KARL-FRED
IPC: A23G3/02
Filed: 1982-05-08
Abstract: Method for manufacturing moulded confectionery products, in which moulding beds, and beyond these recesses which have approximately a hemispherical shape, are impressed, with moulding-bed stamps, into the moulding powder of powder boxes. The powder boxes are subsequently moved from a moulding-bed impression position, in which they were stopped, into an adjacent position, in which they stop again. In this adjacent position, confectionery balls are introduced into the recesses, which balls are subsequently moulded into the confectionery mass in the moulding station. To this end, the work is carried out with a special ball dispenser which allows the confectionery balls to fall into the recesses from a height of a few centimetres. <IMAGE>
Patent DE-3218062-A1 (DE)
Title: Method for introducing liquids into containers such as bottles, cans and the like
Inventor: KAUTZ RALF-DIETER DIPL ING
IPC: B67C3/28
Filed: 1982-05-13
Abstract: In a method for introducing liquids into containers such as bottles, cans and the like, in which the start of the filling is initiated with approximately equal pressure in the liquid container and the container to be filled and the further supply of liquid is set simultaneously and/or with a delay when a probe which determines the filling level is reached, according to the invention use is made of the liquid level or the respective filling height to determine and transmit a delaying and/or correcting pulse. Using this method, the advantage of utilising all factors arising during the filling operation or influencing the filling operation directly for correcting the filling phase is afforded. Since corresponding changes do not appear directly from one bottle to another, it is possible in this way to evaluate the established parameters during the filling of a bottle and to transfer and use them for the filling operation of the bottle following next during a rotation of the filling machine. Overall, this results in excellent adaptation to the particular beverages to be bottled, it being possible to make appropriate corrections from as early as the initial phase of the bottling operation up to the final phase.

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M57/02
Filed: 1982-07-28
Abstract: The invention proposes a fuel injection nozzle for internal combustion engines which has a differential piston (50, 116) as a pressure-increasing device and can be operated at a reduced pressure by an injection pump. The high-pressure cylinder (66, 126) of the differential piston (50, 116) is formed by a bellows-like tubular body (62, 114) which can be compressed resiliently in the axial direction and the internal cross-sectional area of which corresponds approximately to the smaller piston surface of the differential piston and one end of which is attached, preferably centrally, to the differential piston. The resiliently compressible tubular body (62, 114), which is preferably a corrugated tube, simultaneously acts as a return element for the differential piston (50, 116) and as a seal for the high-pressure cylinder (66, 126) relative to the differential piston. As a result, various manufacturing tolerances can be made less narrow and means for discharging leakage oil can be omitted. <IMAGE>

Patent DE-3236205-A1 (DE)
Title: Device for compatible single-sideband modulation
Inventor: KLAAS LOTHAR DIPL ING
IPC: H03C1/60
Filed: 1982-09-30
Abstract: The invention relates to a single-sideband modulation system in which the modulated signal only occupies the bandwidth of the transmitted information whereas its envelope curve contains the information itself within the information band and some spectral components (distortions) above the maximum information frequency. Distortionless recovery of the information is possible by linear envelope curve demodulation with subsequent low-pass filter. The spectral components contained above the maximum information frequency have such little power that the system is suitable for compatible single-sideband modulation for long-, medium- and short-wave broadcasting. Such a signal is generated by connecting in front of an exponential modulator a digital real-time computer which generates an envelope curve with the said characteristics from the information function with the aid of an iteration method.
