Title: Electromotively driven window lifter having a safety circuit
Inventor: STUDLEK GEORG
IPC: H02P7/03
Filed: 1983-02-03
Abstract: What is described is an electromotively driven window lifter which contains a safety circuit against the pinching of fingers and the like during the window-closing movement. The safety circuit comprises a data memory, in which the power/path diagram of an undisturbed window-closing movement cycle is stored. The circuit also contains means which determine the instantaneous power requirement in the initial phase of each closing movement. By means of these data, the stored power/path diagram is corrected in a computing unit. This power/path diagram is assigned a preset tolerance, and the computing unit is programmed in such a way that the drive motor is stopped or its polarity reversed when the power exceeds the tolerance limit, the tolerance limit being set so high for the last phase of the path that the power increase caused by the butting of the pane against the upper window frame causes no reversal of polarity of the motor.

Title: Lidded box
Inventor: DOSSMANN WILHELM
IPC: B65D5/66
Filed: 1983-11-11
Abstract: A lidded box is proposed which is folded from a single-part cardboard blank, has a label stuck over it and whose lid is connected to the bottom part via a fold hinge and, in the closed state, grips over a neck on the bottom part and is placed flush on a peripheral edge strip, the blank for the bottom part consisting of a bottom plate, side parts, front and rear parts and strip portions which are linked thereto and are partially bonded to one another after folding and erecting. In this case, strip portions of the peripheral edge strip are linked in each case to the double-layered foldable side, front and rear parts forming the neck and a backing strip is linked in each case to the narrow sides of two opposite parts linked directly to the bottom part. As a result, a cardboard blank is achieved which is virtually symmetrical to an imaginary longitudinal axis, such that the machine-operated erection operations can be carried out relatively easily by means of devices which are not too bulky. No later separation cuts on the cardboard need to be carried out. The cardboard blank results in an extremely dimensionally stable lidded box with the desired case-type appearance.

Inventor: KIPKE WINFRIED
IPC: H01R39/40
Filed: 1983-12-23
Abstract: A brush assembly for an electrical machine has a holder having a pair of generally parallel side walls having confronting inner faces, a guide wall extending along and between the inner faces and in turn having an inner face defining with the faces of the side walls a passage extending in a longitudinal direction and having a longitudinally forwardly open front end, and an angled surface adjacent the front end. The brush in the passage has a longitudinal guide face longitudinally slidable on the inner face of the guide wall but out of contact with the side walls, an opposite longitudinal face turned away from the guide wall, and axially opposite front and rear ends. A coil spring has a coiled part engaged between the angled surface and the opposite brush face at the front end of the brush to transversely urge the brush against the inner face of the guide wall and a free end extending longitudinally back along the opposite face longitudinally past the rear end of the brush. A pusher block is carried on the free end in the passage longitudinally behind and engaging the rear end of the brush. The rear end of the brush and the pusher block have flatly engaging pusher faces extending obliquely of the direction. Thus as the spring seeks to coil up it pushes the brush longitudinally forward in the passage and transmits transverse force between the pusher block and the brush by means of the oblique pusher faces.

Title: Rucksack made of rigid material
Inventor: LANGER DIETER DIPL ING
IPC: A45F4/02
Filed: 1984-01-21
Abstract: When travelling with rucksacks made of rigid material, in order to be able to carry special articles (valuables, photographic equipment, etc.) during transport by air, train, etc. as well as generally as a separate item of luggage, the rucksack is composed of a plurality of individual cases. The individual hand-held cases can be used as a photographic bag or as hand luggage in the aeroplane, whereas the rucksack case and the other hand-held cases are checked in as luggage or left at the hotel. Nevertheless, the individual cases can be combined to form a rucksack in order to have the hands free on hikes and expeditions and to carry the luggage in an ergonomically favourable manner on the back. In this case, optimum load distribution is ensured by enlarging the storage space in or above the shoulders and by fitting-on additional matching hand-held cases, the intention being for the dead weight of the rucksack to be as low as possible, i.e. light construction, which is possible due to the use of a harness which surrounds the rucksack and secures it at the same time against inadvertent opening.

Title: Screwing clutch with warp spring
IPC: B25B23/00
Filed: 1984-07-17
Abstract: The invention relates to a screwing clutch as an auxiliary clutch for portable electric drills which disengages at an adjustable screwing depth and uncouples the screwing insert from the drive and thus enables the screws to be screwed in to a precise depth without damaging the screw head and the screwing insert. Compared with the known screwing clutches, which mostly use balls as coupling members, the coupling member here is a warp spring (6) which, as a result of the reduced surface pressure, needs only surface-hardened cylindrical parts and requires a lower axial control force, which controls the warp spring via a conical friction clutch (2) (13). <IMAGE>

Title: Modulator for a satellite base band
Inventor: OBERLAENDER DIETMAR ING GRAD
IPC: H04N5/46
Filed: 1984-11-09
Abstract: A modulator for a satellite base band is proposed which comprises a composite-colour signal and two sub-carriers of different level. In order that the received signal contains no interference products and the sub-carriers have the specified level separation from the video carrier, the composite-colour signal and the sub-carriers (TT1, TT2) are, according to the invention, transferred separately and passively coupled into the intermediate-frequency level. For this purpose, the sub-carriers are filtered out of the base band separately by means of in each case one bandpass filter (27, 30) and are set to the desired level separation from the video carrier by means of in each case one level controller (28, 31). The sub-carriers are mixed with an oscillator frequency in a mixer (33). The composite-colour signal is filtered out of the base band and modulates the said oscillator frequency in a modulator stage (21). A bandpass filter (24) filters the video carrier intermediate frequency out of the modulated signal, which video carrier intermediate frequency is passively coupled together with the audio carrier intermediate frequency. <IMAGE>
