Title: Electronic thread monitoring device for embroidery machines
Inventor: HUBER KURT
IPC: D05C13/02
Filed: 1981-07-03
Abstract: The electronic thread monitoring device for embroidery machines comprises a switch (1) which is operated periodically in time with the embroidery by the machine, and by said machine, and which opens and closes a control circuit (20) and a signal circuit (30). A pilot signal (6) is produced by the control circuit (20), which is controlled by the switch contact (1a). This pilot signal (6) represents an input signal (13) for a threshold-value switching stage (11). The output signal (14) from this threshold-value switching stage (11) is interrogated periodically, via the switch contact (1b), by means of a sampling pulse in an interrogation switching state (15). Since, as a result of these measures, the interrogation can take place at any time with respect to the preceding measurement interval, time-linked precise setting at the contacts is no longer necessary. <IMAGE>
Patent DE-3126859-A1 (DE)
Title: Soil-working device
Inventor: KNELL KARL DIPL ING
IPC: A01B11/00
Filed: 1981-07-08
Abstract: A soil-working device has at least one share (3) which is mounted on a support frame (1) and which, during travel, executes a periodic working movement which breaks up the soil in sections. In order to achieve such a loosening of the soil, while reducing the tractive power required, in such a way that coarse, strong clods forming cavities are produced in the lowermost layers and, above these, finer soil particles, in such a way that obstructing areas of compaction are avoided or, if appropriate, are broken up, in such a way that plants or plant parts situated on the soil are worked in or mixed in to the desired depth, and, finally, in such a way that a restructuring of the upper soil area is optionally achieved, a spade (13, 14) or the like is arranged behind the share (3) or each share (3). This spade (13, 14) or the like rotates at the same rhythm as the share (3) in a vertical plane lying in the direction of travel (4) and plunges the share (3) into the broken-up gap at the end of each breaking-up movement. <IMAGE>
Patent DE-3132158-A1 (DE)
Title: Spectacles (glasses) for patients after cataract extraction (cataract lenses) having two-lens optical systems
Inventor: TUEFFERS LOTHAR J
IPC: G02C7/08
Filed: 1981-08-14
Abstract: Cataract lenses have the following disadvantages: strong magnification, narrowing of the field of view (visual field), bringing the subject and obstructions very close, shallow depth of focus etc. These disadvantages are countered here by means of a two-lens optical system which consists in practice of two spectacles, near-eye spectacles and spectacles for normal distances. The dioptric number of the lenses required for the wearer is split between front spectacles and rear spectacles approximately in the ratio of 1:3. As an example, using these spectacles a car driver who has undergone a cataract operation sees in a sharply defined fashion from the dashboard to infinity, something which otherwise requires bifocal spectacles with gaps or trifocal spectacles with discontinuities, which lead to great uncertainties in distance measurement. The rear spectacles can be transferred from one spectacle frame to another by means of a wire bow or similar. In the case of declining visual faculty, it suffices to adapt the front spectacles. This renders these spectacles economic as well, because it is not necessary in every case to exchange the expensive cataract lenses, but only reading spectacle lenses, which are used in massive numbers.
Patent DE-3132922-A1 (DE)
Title: Special grinding machine
Inventor: SCHIEBELHUT MARTIN
IPC: B24B3/55
Filed: 1981-08-20
Abstract: A special grinding machine for machine blades, in particular mowing blades, has a cross slide (14) which can move about a vertical pivot axis (9) and a horizontal pivot axis (13) and, furthermore, can be displaced transversely with respect to a longitudinal guide (2) of the special grinding machine. A connecting rod connects a pin (24) of the cross slide (14) to a machine slide (3), which carries the cross slide (14), such that, when the cross slide (14) pivots about its vertical pivot axis (9), the cross slide automatically also pivots about its horizontal pivot axis (13). The connecting rod has a slot into which the pin (24) engages, with the result that the cross slide (14), by its dead weight, can pivot out to both sides, from a dead-centre position, until it reaches a stop, as achieved from the movement of the cross-slide securing means (10). <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/08
Filed: 1981-10-02
Abstract: A fuel injection nozzle for internal combustion engines is proposed, which has a nozzle body (10) with a valve seat (20) and a valve needle (30), which is pressed by a closing spring (36, 72) against the valve seat (20). The closing spring (36, 72) is integrally connected to the valve needle (30) and formed by a hollow shaft shoulder (36) of the valve needle (30) being shaped by means of a helically running recess (70) into a helical spring element with spring coils (72). Between the spring coils (72) an element (74) of soft elastic material is advantageously inserted so that it can adhere for the purpose of lift damping. The arrangement according to the invention is characterised by an especially low mass of the moving parts and by a reliable connection of the spring coils (72) producing the closing force to the other part of the valve needle (30). <IMAGE>

Title: DC chopper having a turning-off bridge circuit
Inventor: KAHLEN HANS DR DR ING
IPC: H02M3/155
Filed: 1981-10-22
Abstract: The invention relates to a DC chopper having a turning-off bridge circuit, consisting of a main thyristor (T1) and four turning-off thyristors (T2, T3, T4, T5), connected to one another in a bridge circuit. The commutating capacitor (CK) is arranged between the common connecting points (A, B) of the turning-off thyristors. A charging and voltage maintaining circuit is proposed for the commutating capacitor (CK), having the following features: the two connecting points (A, B) of the commutating capacitor (CK) are connected on the one hand in each case via charging resistors (R1, R2) to the positive line of the supplying DC voltage source, and on the other hand in each case via protection resistors (R3, R4) and transistors (V1, V2) to the negative line. The transistors (V1, V2) are in each case driven via base resistors (R5, R6) and the protection resistors (R3, R4). The charging resistors (R1, R2) may be replaced by transistors (V3, V4), in order to reduce the charging time of the commutating capacitor (CK). <IMAGE>

IPC: G09F11/295
Filed: 1981-12-16
Abstract: This rolling tape is moved by a motor past a display window by being rolled up and rolled off, each destination being associated with a destination-specific binary code word by lateral point and line markings, the passing code words being detected by means of reflection-type light barriers and compared with the code word set by means of coding switches in accordance with the desired destination, a comparator determining the direction of rotation of the drive motor when the code words are not equal and stopping the drive motor when they are equal, according to Patent... (Patent Application P 3113124.7). It is characterised by the fact that the destination is selected during the fast mode of the drive motor (106) until the code words are equal in the comparator, an overflow being compensated for by reversing and running the drive motor (106) back at creep speed. <IMAGE>
Patent DE-3200715-A1 (DE)
Title: Arrangement for suspending a facade panel
Inventor: HAEUSSLER ERNST DR ING
IPC: E04F13/08
Filed: 1982-01-13
Abstract: The invention relates to an arrangement for suspending a facade panel in front of a building outer wall. Included in the arrangement are fastening bolts which are inserted into the building outer wall, connection devices arranged on the facade panel and pendulum hangers. The fastening bolts and the connection devices are arranged on either side of the central axis of the facade panel. The pendulum hangers are connected, on one side, to the fastening bolts and, on the other side, to the connection devices. Furthermore, they are adjustable in length with the aid of an adjusting-screw connection. On one side of the facade panel, the pendulum hangers form a combination of two pendulum hangers which extend obliquely towards one another and obliquely with respect to the vertical. On the other side, the pendulum hanger is, in a known manner, arranged vertically. By adjusting the length of the pendulum hangers in combination, said substantially vertically arranged pendulum hanger can be deflected relative to the vertical. Consequently, the facade panel can be aligned, by length adjustment of the pendulum hangers, both with respect to the horizontal and also with respect to the vertical. <IMAGE>

Title: Weighting resistor arrangement for heater sensors
Inventor: GOTTFRIED GERD-ULRICH DIPL ING
IPC: G01K7/22
Filed: 1982-02-04
Abstract: A weighting resistor arrangement for matching measurement circuits containing detectors and comparative sensors to the heating power of heaters, for floor heating systems or similar heat-generating devices has a carrier plate (7) which contains resistors (2, 3, 4, 5, 6) whose resistance values correspond to prescribed stages of the heating power. The resistors (2, 3, 4, 5, 6) are bridged by easily breakable short-circuit lines (11, 12, 13, 14). Furthermore, at least a portion of the resistors (4, 5, 6) are connected at the terminal ends (17) via easily breakable lines (18, 19, 20, 21, 22) to a common output line (23). An additional, easily breakable line (24) is arranged between the start of the series-connected resistors (3, 4, 5, 6) and the terminal (17), which is further from the series circuit, of a resistor, of the series, which follows the first resistor. By breaking short circuit lines and/or the other breakable lines (18, 19, 20, 21, 22, 24), it is possible to select combinations of resistors such that sensitive matching to prescribed heating power stages is possible. <IMAGE>
