Title: Ground-working appliance having oscillating coulters and a cutter roller
Inventor: EGGENMUELLER ALFRED DR ING
IPC: A01B49/02
Filed: 1984-02-10
Abstract: The invention relates to a ground-working appliance having oscillating coulters 6, driven transversely to the direction of travel, and a cutter roller 12 which cooperate directly one behind the other. By means of the drive from the power take-off shaft, the coulters have only a slight traction resistance and peel the ground intensively. The cutter roller 12 engages into this loosened ground before it falls back, mixes it and throws it rearwards. It also sweeps over the coulter holders 25, so that clogging is prevented. If the cutter roller 12 is raised by means of a spindle 31, it works only on the surface and mulches in the organic substances deposited there. Finally, it can also be put out of action completely. The working results can be varied by varying the frequency and amplitude on the coulters 6 and the rotational speed on the cutter roller 12. The press roller 32 ensures that the ground is closed over. <IMAGE>

Title: Circuit arrangement for inputting an analog voltage value at zero potential into a digital evaluating circuit
Inventor: POSCHMANN WERNER DIPL ING
IPC: H03M1/00
Filed: 1984-02-11
Abstract: A circuit arrangement is specified which enables an analog voltage value to be input at zero potential into a digital evaluating circuit with the least possible complexity. For this purpose, an A/D converter circuit operating in accordance with the dual-slope method and exhibiting an integration section and a control section is used. The potential isolating circuit means (relay, optocoupler) are then arranged in such a manner that the potential is isolated between integration section and control section. Since there are only three DC connections between the two circuit sections at this point, the expenditure of potential-isolating circuit means is much lower than when the potential is isolated at the digital output of the A/D converter circuit. <IMAGE>

Title: Process for the preparation of  omega -functionalised aldehydes by reductive ozonolysis of unsaturated fatty acid esters or unsaturated fatty alcohols
Inventor: MAJMUDAR SURESH DR
IPC: C07C29/48
Filed: 1984-11-07
Abstract: The invention relates to a process for the ozonolysis and subsequent reductive cleavage of unsaturated fatty acid esters and/or unsaturated fatty acid alcohols to give  omega -formyl-substituted esters and/or alcohols by treatment in a protic solvent or solvent mixture with ozone of the unsaturated material used and subsequent hydrogenolytic cleavage with hydrogen on metal catalysts. The distinguishing feature of the novel process is that at least the catalytic hydrogenolytic cleavage is carried out in the presence of added water. In the particularly advantageous embodiment of the novel process, the ozonisation is carried out without addition of water, while the water added according to the invention is additionally added to the reaction mixture obtained from the ozonolysis step and the subsequent hydrogenolytic cleavage is carried out with hydrogen on metal catalysts in the presence of the aqueous phase. Preferred protic solvents are lower carboxylic acids, in particular propionic acid, optionally mixed with glycol hemiethers, preferably methylglycol.

Title: Forwards viewing mirror, especially for motor vehicles
Inventor: AMBROS RICHARD
IPC: B60S1/04
Filed: 1985-03-28
Abstract: The invention relates to a forwards viewing mirror which is combined with a rear view mirror and by means of which a glance of a driver directed through the windscreen in the moving out direction is deflected to the side of the vehicle in the direction of travel. The mirror assembly is mounted on a holder so as to be pivotable by means of a driver's door and on the side on a front mud guard so as to be pivotable outwards over the holder, the rear view mirror being viewable via a side window, as usual. A glass wiping blade which is mounted so as to be pivotable about a vertical axis is provided for a curved viewing glass of the forwards viewing mirror, wipes the entire viewing glass clean and is held in a contact-free manner in its rest pivot position by means of a trough moulded onto the edge of the glass, which prevents freezing of the wiping lip to the glass at low temperatures. The glass wiping blade remains in constant contact with the glass during wiping. A pump which has a water reservoir and is accommodated in the mirror assembly between the forwards viewing mirror and the rear view mirror ensures that the viewing glass is supplied with water, a double-walled dismountable canopy being arranged above the said viewing glass.

Title: Wind-collecting vane for horizontal turbines which can rotate about a vertical axis
Inventor: HERTER ERICH
IPC: F03D3/06
Filed: 1985-05-17
Abstract: The wind-collecting vane is intended for horizontal turbines which can rotate about a vertical axis. It consists of two vane profiles which are arranged next to one another with a radial spacing, are joined by webs, have a slim cross-section and delimit a throughflow channel. In order, given that the strength design requirements can be fulfilled, to lend such a wind-collecting vane self-starting properties, on the one hand, but also as small as possible an "internal" resistance, on the other hand, the wind-collecting vane is constructed in such a way that the two vane profiles (1, 2) are constructed with their external surface contours (3) as parts of the external surface contour (4) of a thick, self-starting vane profile (5). In this arrangement, the vane profiles (1, 2) delimit the throughflow channel (7) by means of their internal flanks (6), which extend rectilinearly in the throughflow direction and parallel, or approximately parallel, to one another. <IMAGE>

Title: Directional antenna
Inventor: HILSE WOLFGANG DIPL ING
IPC: H01Q19/02
Filed: 1985-07-17
Abstract: In the case of a parabolic reflector antenna which is supplied at the focus directly from the primary radiator (4), influencing of the reflection (which influencing acts independently for two orthogonal linear polarizations) for compensation of the feedback reflection from the parabolic reflector (3) on to the primary radiator (1) can be achieved in that, in addition to a vertex plate (8) which is optimized for one polarization plane with respect to the reflector separation and diameter and whose surface forms a first reflection plane (1), a second reflection plane (2) of identical dimensions is introduced at a suitable distance in front of said first reflection plane (1) which second reflection plane (2) acts exclusively in the other polarization, that is to say in the orthogonal polarization. A directional antenna constructed in accordance with the invention can be used as a satellite or directional-radio antenna for double-polarization operation. <IMAGE>

Title: Path-dependent synchronous pressure control for double-acting presses, in particular laminating presses
Inventor: AENGENEYNDT WOLF DIPL ING
IPC: B30B15/24
Filed: 1985-07-19
Abstract: The invention relates to a synchronous pressure control for laminating presses in which in each case a pressure balance with a pressure gauge is connected between pressing cylinders and control valves. Furthermore, between a pump unit for the pressing cylinders and the control valves, a differential pressure regulator is connected which maintains a constant differential pressure predetermined in dependence on the pressure measured downstream of the control valves. A simple and functional synchronous pressure control is thus provided which operates with relatively low energy losses, irrespective of whether a low pressure is set only for traversing the pressing carriage or a high pressure is set for the pressing operation. <IMAGE>

Filed: 1986-02-08
Abstract: The circuit arrangement according to the invention is intended for monitoring large glass areas, for example shop windows, which consist of a number of assembled part-panes. The glass breakage detectors, which are in each case functional independently of one another, with their own clock generators and frequency generators are interconnected in such a manner that the individual evaluating circuits are driven in parallel via a common clock line fed from a single clock generator, and the transmitters, in each case connected individually, are fed from a single frequency generator by a common frequency line. A further embodiment of the circuit arrangement provides for the glass breakage detectors to operate in time-division multiplex mode so that only a single glass breakage detector is always active at one time.
Patent DE-3606483-A1 (DE)
Title: Cable reel device
Inventor: STETTNER GERHARD DIPL ING
IPC: H02G11/02
Filed: 1986-02-28
Abstract: A cable reel device has a cable drum 1, 2 for an electrical cable (4), which cable drum (1, 2) is supported such that it can rotate about a stationary journal (3) which has sliprings (5) arranged thereon. Sliding springs (6) which are electrically connected to the cable are located inside a hub (2) of the cable drum, the support (7) which holds the sliding springs (6) being held displaceably in an opening in the casing (10) of the hub. In order to achieve simple, screwless installation and strain relief for the carrier and cable, the carrier (7) is inserted into the hub such that it can be displaced radially, and the cable (4) is guided away from the carrier (7), approximately in the insertion direction (14) and is guided through a perforation (15) in the hub (2). The cable (4) in this case rests against the casing (10) between the perforation (15) and an annular eye, which is provided remotely therefrom on the carrier (7), even when the cable (4) is unwound to some extent. In consequence, the only tensile forces on the cable (4) are those which fix the carrier (7) in its operating position in the hub, the frictional lock between the cable sheath and the hub casing contributing to the strain relief. <IMAGE>
