Patent DE-3124737-A1 (DE)
Title: Multi-row sowing machine, especially seed drill
Inventor: KIRCHBERGER FRANZ
IPC: A01C7/20
Filed: 1981-06-24
Abstract: The invention relates to a multi-row sowing machine, especially a seed drill, of which the seed insertion elements engaging into the soil are pressed more or less firmly against the soil during the seeding by means of an adjustable prestressing force as a function of the soil state, in order to make the sowing furrows, on the bottom of which the seed grains are deposited. The seed depositing depth has already hitherto been maintained relatively accurately, but without taking into account whether the particular set depositing level adjoins the moisture-carrying capillary soil layer or not. But seed grains need moisture so that they can germinate. The invention guarantees that the furrow bottom (5) adjoins the moisture-carrying capillary soil layer (71), in that, during seeding, the seed insertion elements (16, 160) are set in vertical vibrations by at least one vibration generator (60). As a result of these vertical vibrations of the seed insertion elements (16, 160), the usually relatively loose soil under the furrow bottom (50) is additionally compacted to such an extent that a "capillary bridge" to the lower moisture-carrying soil layer (71) is made. The invention is mainly used for cereal sowing. <IMAGE>

Patent DE-3144334-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: H03M1/22
Filed: 1981-11-07
Abstract: An incremental path measuring instrument is disclosed which includes a plurality of reference marks R1 . . . Rn which are interposed between respective code marks C1 . . . Cn. The reference marks and code marks are applied alternately and serially to the reference track included on the measuring scale. A scanning unit is included in the measuring device for scanning in series the reference marks and the code marks. Each of the code marks is unique, and only one of the two adjacent code marks and the respective reference mark must be scanned by the scanning unit in order to identify the reference mark unambiguously. When absolute position values are allocated to respective individual reference marks, the incremental path measuring device can operate in a quasi-absolute mode of operation, since then the position of each of the reference marks is established with respect to a predetermined zero point. Preferably, the code marks each contain beginning of block and end of block symbols in addition to the identifying information needed to identify the respective reference marks. The disclosed path measuring device includes an evaluation circuit which includes a circuit which automatically adapts the trigger threshold required for signal evaluation to the actual amplitudes of the signals.
Patent DE-3146174-A1 (DE)
Title: Punching press having an open frame
Inventor: MUELLER SIEGFRIED
IPC: B30B15/04
Filed: 1981-11-21
Abstract: In punching presses having an open frame, the frame spring occurring under load makes itself felt in a disadvantageous manner by the top part of the frame deflecting elastically both upwards and rearwards under load. In the known constructions, the guide for the ram in the frame is fixed so that the frame, during its deflection caused by the loading, carries the guide for the ram with it to the rear and thus pivots it against the table accommodating the bottom die so that the top and bottom die tilt against one another during the cut. The impairment which this causes in both the cut and the life of the dies is removed by the guide being arranged independently of the frame on the table and being connected to the latter in a flexurally rigid manner.

Title: Device for producing an image by means of one or more streams of droplets
Inventor: BLUME ROBERT DIPL PHYS DR RER
IPC: B41J2/03
Filed: 1981-12-08
Abstract: In a device for producing an image by means of one or more streams of droplets, the ink serving for imaging flows out of a nozzle opening (3a) at high pressure. During the flowing-out, the stream is divided up into individual droplets whose mutual spacing corresponds to the wavelength ( lambda ) of the hydrodynamic oscillations produced during the flowing-out process in the nozzle chamber (3) or in the emerging stream or imposed from the outside. In order to obtain a uniform droplet size and uniform droplet spacing ( lambda ) without bulky external oscillation exciters, the nozzle opening (3a) has a slightly elliptical cross-section which causes the ink stream, which, due to the surface tensions, attempts to form a circular cross-section with a central radius (aO), to oscillate hydrodynamically with a uniform wavelength ( lambda ). <IMAGE>

Patent DE-3242997-A1 (DE)
Title: Position indicating system
Inventor: ROTHER DIETRICH DR ING
IPC: G01S5/14
Filed: 1982-11-20
Abstract: In the position indicating system, a user's position is calculated in a user station (N) from the distances to several parent television transmitters (S1, S2) and/or fill-in television transmitters (FS11, ..., FS21,...) and the positions of these television transmitters which are known in the user station. The distances to the television transmitters are determined by means of one-way range measurements. The time markers needed for one-way range measurement are derived from the television signals of these television transmitters. The television transmitter which has radiated the television signal is identified with the aid of the frequency of the received television signal. To synchronise all stations of the system, a ground control station (K) is provided which operates in conjunction with a transponder (T) arranged on a satellite. The transponder signals are also received by receiving stations (E) which are allocated to the parent television transmitters (S). In the receiving stations, correction values are determined for the parent television transmitters and these are transmitted to the users. The fill-in transmitters are in each case coupled to the associated parent television transmitter. <IMAGE>
