Patent DE-3440157-A1 (DE)
Title: Sensing system
Inventor: ROTHE ERNST
IPC: G02B26/10
Filed: 1984-11-02
Abstract: A sensing system is described, with a light source (1), with a collimator objective (2) which collects the light of the light source, with a sensing objective (3) which images the light collected from the collimator objective (2) on a surface (4) to be sensed, and with a mirror (5) which is arranged between collimator objective and sensing objective, which mirror, in order to obtain smaller sensing movements on the surface (4) to be sensed, can be swivelled about the position in which it deflects the beam path of the sensing system by 90 DEG . Sensing systems of this kind are used for example in video disk players. According to the invention, the collimator objective has a maximum of only two lenses with a positive refractive power, the shutter 6 of the sensing system being arranged in the sensing objective 3. The sensing objective according to the invention has a consciously introduced spherical aberration and coma which compensate the spherical residual aberration of the collimator objective, which is non-correctable due to the selected structure, for all the positions of the mirror. The spherical aberration of the collimator objective actually acts in specific positions of the mirror like an additional asymmetry error. The sensing system according to the invention can be used in a virtually diffraction-limited fashion for all positions of the mirror 5 occurring during operation. <IMAGE>

Title: Device and measuring arrangement for indirectly determining plate thicknesses
Inventor: ROEHRER RALF DIPL ING
IPC: G01B7/06
Filed: 1985-02-19
Abstract: In order to determine the plate thickness of ferromagnetic plates, it is advantageous to use measuring arrangements having a magnetic circuit and which determine the thickness of the plate via the level of the magnetomotive force. The disadvantages of the known arrangements consist in that it is necessary to use permanent magnets which can damage the plate to be tested by their continuously acting force, and in that it is also impossible thereby to measure different sorts of plate and large plate thicknesses. These disadvantages are eliminated by the use according to the invention of an electromagnet whose inductance, which varies with the plate thickness, is used to determine the plate thickness. <IMAGE>

Title: Machine for electrical pressure welding or pressure soldering
Inventor: MOSBACHER ALBERT
IPC: B23K11/31
Filed: 1985-11-11
Abstract: Two electrodes (11, 12) which can cyclically be moved together and apart have clamping surfaces (15, 16) facing one another, which serve to clamp the workpieces which are to be welded and for feeding in the current required for this process. To reduce, especially in the batchwise welding or soldering of small articles, the frequency of wear resulting from heat, build-up, and hence to reduce the frequency of the requisite replacement of the electrodes (11, 12) or of the electrode inserts (18) which carry the clamping surfaces (15, 16), the clamping surface (16) of one electrode (12) is constructed larger than the clamping surface of the other electrode (11), and means (44, 42, 36, 35, 32, 27) are provided in order to shift the one electrode (12) with respect to the other (11) between successive cycles. As a result, in successive cycles, different portions of the area of the larger clamping surface (16) face the clamping surface (15) of the other electrode (11). <IMAGE>

Title: Process for vibratory shaping, and vibratory compressor (compacter) for carbon compositions
Inventor: WILKENING SIEGFRIED DR ING
IPC: B30B11/02
Filed: 1985-11-14
Abstract: In the prior art processes, a heavy covering weight is required, which rests as a top load on the carbon composition. The moulding box is coupled to the oscillating weight of the vibration table, so that the oscillation amplitude is reduced or a vibrator of greater drive power has to be employed. If the compression (compaction) is to take place in vacuum, a hood, below which the covering weight is located, is placed on the moulding box in the prior art processes. This imposes an additional load on the vibrating table and because of the sequence of operations different positions must be provided for filling the moulding box and for compacting the carbon composition. The characteristic feature of the compressor (compacter) according to the invention is that the moulding box itself serves as the top load. To release the compacted body, the moulding frame (8) is lowered. Vacuum connection is made via a suction nozzle (25) in the removable cover plate (23) of the moulding box. In this process, the covering weight and the vacuum hood can be dispensed with and a vibrator of lower drive power can be used. Since the filling and compaction is possible in one and the same position of the moulding box, the working cycle is shortened and hence the productivity is increased. Moulding and compression (compaction) of green carbon compositions. <IMAGE>

Title: Drive band for gun ammunition
Inventor: HEINRICH HANS-JOERG DIPL ING
IPC: F42B14/02
Filed: 1985-12-19
Abstract: A continuous drive band (9) which is constructed as a supporting element has the property, in order to compensate for tolerances between the barrel (1) and the ammunition (2), that it can be expanded elastically by ram pressure, inertia force or by centrifugal forces in the case of spinning ammunition, and this increase in diameter produces the tolerance (clearance 12) between the barrel (1) and the projectile or between the barrel (1) and the sabot (2). The arrangement of the drive band (9) in the front region of the ammunition reduces the oscillation of the projectile in the weapon barrel. <IMAGE>

Title: Electrolysis with vibratory agglomeration for preferably gypsum-containing residues in the scrubbing solution
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-02-15
Abstract: The main application P 3546112.8 relates to a method of operating electrolysis for the simultaneous separation of SO2 and NOx from flue gases, in which the conductivity of the scrubbing solution is kept in a particular range. It has been shown that the conductivity of the scrubbing solution is influenced by solids which are present in the scrubbing solution. Moreover, encrustation on the membranes of the electrolysis cells negatively influences the process. In order to avoid these disadvantages, according to the invention it is proposed that the scrubbing solution and/or the electrolysis cell itself and/or the housing is stimulated by ultrasound and/or is stimulated to vibrate alone and/or additionally by vibrators. The cleaning of the electrolysis cells and the membranes and the agglomeration of the solids in the scrubbing liquid is preferably achieved by ultrasonic excitation alone.
