Title: Seat, especially a motor-vehicle seat
Inventor: MUHR DIETER
IPC: B60N2/62
Filed: 1981-10-08
Abstract: In a seat, especially a motor-vehicle seat having a backrest and a seat cushion connected to this, a thigh support is arranged pivotably in the front region of the seat cushion on the seat-cushion carrier and is vertically adjustable via a manually actuable setting mechanism. In order, with the thighs of the seat user raised, to bring the thigh support to selectable height automatically by one-handed actuation and lock it in this position, the setting mechanism possesses locking tabs vertically displaceable automatically on both sides during setting and coupled to the thigh support. For blocking, these locking tabs can be locked fixedly on the seat-cushion carrier at one of a plurality of selectable heights. At the same time, as is evident especially from Figure 2, the thigh support is connected rotatably to the locking tab via supporting tabs, there being arranged at the point of articulation between the locking tab and supporting tab a blocking bolt which is axially displaceable by means of a central hand lever and which, for blocking, engages into one of a plurality of blocking receptacles in a bearing cheek of the seat-cushion carrier.

Title: Cylindrical body made of easily breakable material
Inventor: WOERDER HANS
IPC: A61J1/06
Filed: 1981-10-24
Abstract: In order to improve the breakage of cylindrical glass bodies which are embedded in a flexible sleeve, the glass body has one or more intended breakage points which are formed by circumferential constrictions on the cylindrical body. If the cylindrical body has the shape of a circular cylinder, the cross-section of the circular cylinder can be tapered conically at one end. The circular cylinder can also have different diameters, the larger diameter extending over approximately 2 DIVIDED 3 and the smaller diameter over approximately 1 DIVIDED 3 of the height of the cylindrical body. In this case, the smaller diameter of the cylindrical body is identical to the diameter of the circular cylinder in the region of a constriction. The cylindrical body filled with a cleaning liquid is inserted in a plastic sleeve which is provided with a flexible stopper. During use, the cylindrical body is broken so that the cleaning liquid can be absorbed by the stopper and cleaning can take place by dabbing a soiled place.

Title: Internal clamping mandrel
Inventor: WIDMANN KARL
IPC: B23B31/40
Filed: 1981-11-20
Abstract: Provided at the front end of a mandrel shell (6) is a clamping head (4) with a clamping shell which is formed from one or more clamping jaws (7) and in which a wedge body (11) engages which can be displaced by a clamping screw (5) in the longitudinal direction of the mandrel shell (6) and thereby expands the jaw shell in such a way that it clamps a hollow body, such as a broken-off thread end of an installation line, from the inside and carries it along or screws it out of an external thread by turning the mandrel shell (6) in the release direction. The mandrel shell (6) has a hexagonal external surface run up to the shoulder (10) of the clamping head, so that a spanner can be inserted tightly against the clamping head on the shell. Provided clamping jaws (7) are made in one piece with the mandrel shell (6), grooves or other weakenings of the cross-section can be made at the shoulder point (10) in order to increase the possible deflection angle. In addition, two or more clamping jaws can be loosely inserted and, just like a C-shaped expandable ring bush, can be attached to the mandrel shell (6) by coupling means. <IMAGE>

Patent DE-3203856-A1 (DE)
Title: Contact system for single-column pantograph disconnectors
Inventor: SCHULZ KLAUS
IPC: H01H31/36
Filed: 1982-02-03
Abstract: In a contact system for single-column pantograph disconnectors a pair of moving main contacts (3, 4) fitted to the ends of the pantograph interacts with a mating contact (1) mounted on the high-voltage line. Fitted to both main contacts (3, 4) in a projecting manner are initial contacts (5, 6) which close during switching on before the main contacts (3, 4) and open during switching off after the main contacts (3, 4). In order to achieve a snapping movement between the mating contact (1) and the initial contacts (5, 6), a magnetic body (7a, 7b) is provided whose retaining force presses the initial contacts in the switched-on position against the mating contact, each of the main contacts (3, 4) with its associated initial contact (5, 6) being coupled via a spring (9) which is braced in the opening direction and counteracts the retaining force of the magnetic body (7a, 7b). <IMAGE>
Patent DE-3209204-A1 (DE)
Title: Winder for receiving a tube package
Inventor: DREIER JUERGEN ING GRAD
IPC: B65H49/32
Filed: 1978-11-21
Abstract: The winder (H1) has a spool (4) which can be rotated about a first axis (18) and onto which a tube package (24) can be fitted. The spool (4) is mounted on a spool carrier (3) which, in turn, can be rotated about a second axis (14) which runs perpendicular to the first axis (18). The bearing (11), in which the spool carrier (3) is mounted, can be rotated about a third axis (10) which runs perpendicular to the first axis (18) and to the second axis (14). Due to the rotatability of the spool carrier (3) about the second axis (14), twisting of the tube (26) unwound from the package is avoided. The winder can also be used without the third axis (10). The third axis affords the additional advantage that the spool can be set to the drawing-off direction of the tube (26). <IMAGE>

Patent DE-3217986-A1 (DE)
Title: Circuit for cross-monitoring of multi-core control lines in intrinsically safe circuits with half-cycle control
IPC: G05B9/02
Filed: 1982-05-13
Abstract: In intrinsically safe installations which operate using half-cycle technology in order to guarantee accident-proofing, and in which the central control unit is controlled by a plurality of command transmitters, supplied from a common power supply, via multi-core lines, hazardous operating situations occur when cores of different circuits are short-circuited as a result of an external mechanical influence on the line. This is prevented by the following safety circuit: in each case two optocouplers (4-5, 6-7), which are connected in reverse parallel are connected in series with the contact in front of and behind each command transmitter (1) with a changeover contact and diode (2, 3) connected in reverse parallel (positive half-cycle = on, negative half-cycle = off) so that the corresponding phototransisters and EXOR gates (8, 9) connected to their emitters are selected in every switch position, with the consequence that a quiescent current for a relay (13), whose tripping initiates a switching-off process in the controller, is connected via an AND-linking (10) of the EXOR gates and a transistor amplifier (12). This circuit guarantees that no inadvertent self-starting takes place in the event of line defects of any type or, however, that already running drives are stopped. <IMAGE>
Patent DE-3227569-A1 (DE)
Title: Pulse-duration modulation method
Inventor: MOSCHETTI ARMANDO DR ING
IPC: H02M7/529
Filed: 1982-07-23
Abstract: This pulse-duration modulation method is used for the purely digital formation of phase-potential nominal values (R*, Y*, B*) for driving an inverter, having a DC voltage intermediate circuit, for the generation of a three-phase system which is variable in terms of its frequency, amplitude and phase. It is possible to supply, for example, an asynchronous machine used for traction purposes, by means of such a three-phase system. In order to form the phase-potential nominal values (R*, Y*, B*), phase angles ( phi ) which progress as a function of the frequency (K x f1) are produced for a sinusoidal nominal-value voltage (Unom). A computer forms the sine values corresponding to the phase angles ( phi ) at equal time intervals (2 DELTA  T), and multiplies said phase angles by a predetermined drive value (a). The computer uses the instantaneous values (av) obtained in this way for the phase-potential nominal values (R*, Y*, B*) to form the time intervals (T1 nu , T2 nu , T3 nu , T4 nu ) for the pulse duration of the nominal values which run in a rectangular shape. In addition to this, the implementation of non-synchronised pulses is described. <IMAGE>
