Title: Method and arrangement for compensation of current fluctuations resulting from sudden motor-data changes
Inventor: HEILMANN GERHARD DIPL ING
IPC: B60L15/00
Filed: 1985-01-17
Abstract: In order to compensate for current fluctuations as a consequence of sudden motor-data changes in converter-supplied three-phase control drives with a DC voltage intermediate circuit and current regulation, which is influenced additively by a stator frequency as the sum of the measured rotation frequency of the motor and a preselected motor slip frequency which determines the torque, the following method is proposed according to the invention: the stator frequency (F1) is corrected by means of a slip-magnitude supplement ( DELTA F2) which is obtained from the low-frequency voltage fluctuation ( DELTA Uc) in the DC voltage intermediate circuit (2) and, by phase shifting, is brought into anti-phase with the current fluctuation ( DELTA i) in the motor (1). An arrangement for carrying out the method is described. <IMAGE>

Patent DE-3511768-A1 (DE)
Title: Electromagnetic transducer
Inventor: LUHN ERNST DIPL ING
IPC: G01N29/24
Filed: 1985-03-30
Abstract: The invention relates to an electromagnetic transducer for exciting and receiving ultrasonic waves in testing electrically conductive material without the use of coupling means, chiefly in the testing of workpieces made from steel. Whereas to date printed conductors have been arranged on flat printed circuitboards and could be connected there to form coils, the invention provides magnetising windings in association with pin-shaped RF cores. The latter form the base elements of a multiple arrangement in which they must exhibit specific spacings prescribed in accordance with the invention. They can then be operated as singular point or line emitters or in a linear or planar array, and as planar emitters, and facilitate an improved signal-to-noise ratio in ultrasonic testing, specifically in particular with the use of very high transmitter frequencies. The crosstalk sensitivity is reduced in this case in such a way that the error detection is substantially improved.

Title: Cooling device for a tubular film produced by extrusion
Inventor: RENK PAUL
IPC: B29C48/10
Filed: 1985-06-08
Abstract: A blown film system is described in which the output capacity is significantly increased by a specific stabilizing and post-cooling device for the film bubble (4). This device consists essentially of a post-cooling cylinder (17) arranged, so as to be height-adjustable, at a distance above the air blowing nozzle (24) of the cooling ring (5) and possible air guide rings (6, 15). A constricting ring (23) follows said post-cooling cylinder (17) at an axial distance. Between the last air guide ring (6) and the post-cooling cylinder (17) there is an expansion zone (16) which permits an air exchange between the heated cooling air stream which flows axially out of the air guide ring (6) and disperses radially and the ambient air. The expansion zone (16) is delimited in the radial direction by a filter cylinder (10) which on the one hand is supported on the cooling ring (5) and on the other hand is axially closed off at its upper end by a flange ring (13). Upstream of the constricting ring (23) there is located a wall region which, by contrast with the radially impermeable post-cooling cylinder (17), is air-permeable so that a part of the cooling air can flow out radially upstream of the constricting ring (23), while cooler ambient air is sucked in downstream thereof. <IMAGE>

Title: Rivet press for setting functional haberdashery elements, such as snap fastener parts, on backings
Inventor: HERTEN ERNST
IPC: A41H37/00
Filed: 1986-01-04
Abstract: In a rivet press for setting functional haberdashery elements, such as snap fastener parts, on backings by means of deformable fastening elements, apart from the lower tool a two-part upper tool with lifting movement is used. The latter comprises tongs for positioning an upper element and a pneumatically operable upper ram. Furthermore, a finger guard device is provided on the tongs which prevents a downward movement of the upper ram down to a particular safety distance if an obstacle arises in the movement path of the tongs. In order to achieve a simple and reliable finger guard device and, in this case, to guarantee satisfactory riveting, it is proposed to provide the lifting movement of the tongs via a pedal, but the lifting movement of the upper ram via a pneumatic piston/cylinder drive, a pulse valve which can be operated pneumatically by means of alternative control pressure being reversible between two operating positions and thus providing at least the piston-side end of the cylinder with compressed air and causing the downward movement of the upper ram. In this case, the tongs are provided with a pair of cams which move along with them and act on associated control valves which supply the alternative control pressure for reversing the pulse valve. However, the second cam and its control valve also form the finger guard device when the significant cam surface is set back relative to the active end of the tongs to the extent...

Title: Machine for fitting a brush body with bristles
Inventor: THOMA PIUS
IPC: A46D3/06
Filed: 1986-05-12
Abstract: The bristles (19) are often inclined in the transverse and longitudinal directions of the brush. Corresponding to this inclination, during the brush manufacture the brush body (18) and tool (7) have to be inclined relative to one another. The inclination in the longitudinal direction of the brush is brought about by inclining (6) the tool (7). The inclination in the transverse direction of the brush is brought about by inclining (22) the brush body (18). The brush can be moved horizontally by a transverse and longitudinal support (12 and 11 respectively), and both supports are height-adjustable (15). The tool (7) has an axial feed movement (9). The axis of inclination (26) of the tool and the axis of inclination (23) of the brush intersect. Inclination of the tool (7) and inclination of the brush (18) thus only result in inclination of the tool and the brush body relative to one another. The transverse and longitudinal feed movements of the brush relative to the tool are carried out from hole to hole in the brush body by the transverse and longitudinal slides (12, 11). The vertical feed movement of the brush relative to the tool is carried out from hole to hole by the vertical adjustment (15). By dividing the inclination movements onto the tool (7) and the brush (18) and using straight supports (11, 12), a compact machine can be achieved. By inclining the brush in an axis which lies at right angles to the axis of inclination of the tool, the tool tip lying at the intersection of the two axes, the spacings of...

Patent DE-3627830-A1 (DE)
Title: Line release
Inventor: DECKERT ARNOLD
IPC: A01K91/10
Filed: 1986-08-16
Abstract: The novelty of the line release shown in the drawing and description resides in the fact that, when the catch bites, the fishing line (p), which is guided through the lower line ring (o) via the release (b), is tightened. As a result, the release is drawn forwards and, because of the weight of the counter-weight (c), falls completely downwards. The stop (g) is then released by the stop fixer (f) so that it abruptly swings out from a torsion rod or helical spring to the stop limiter and so automatically or independently pulls the fishing line (p) so as to attach the catch more securely to the hook. <IMAGE>
