Title: Interior lighting fixture with rocker switch
Inventor: STOECKEL-MENZEL WERNER
IPC: B60Q3/02
Filed: 1983-09-07
Abstract: An interior lighting fixture, in particular for motor vehicles, has a rocker switch whose operating rocker interacts via latching cams or similar profiles with corresponding grooves or the like of a switch spring. At the same time, the rocker switch is provided with operating cams which can press contact springs against this switch spring. The switch spring therefore has three functions: It keeps the operating rocker mechanically in its bearing and in its switch position and simultaneously ensures the electrical contact to the lamp. For use in motor vehicles, in particular, it is preferred to provide three switch positions, it being the case that in one of these switch positions the lamp is permanently switched off, in a second switch position the lamp is permanently on, and in a third switch position the lamp is switched on only if a door contact is closed.

Title: Printed-circuit board assembly
Inventor: TUERK WILFRIED DIPL ING
IPC: H01R12/55
Filed: 1983-09-30
Abstract: The invention relates to a printed-circuit board assembly which consists of a printed-circuit board (8) fitted with integrated modules, of a plug connector part (6, 7) and of a pressure component, for example a cooling device, which exerts a pressure on a printed-circuit board surface. In order to prevent bending of the printed-circuit board by means of the pressure component or by means of insertion or withdrawal processes causing lead fractures or the like, an opposing pressure is produced on the printed-circuit board and an elastic connection is produced between the plug connector part and the printed-circuit board. To this end, the elements of the plug connector part which make contact are distributed uniformly over the area of the printed-circuit board. Said elements in each case consist of a spring shaft (5) for holding a contact pin and of a connecting tab which rests in a sprung manner on the printed-circuit board and whose end which rests on the contact guide surface (1) is constructed as a straight sheet-metal strip (2) and presses with its end surface (3) onto the surface (1) which makes contact, and its other end is connected to the spring shaft (5) via a leaf spring part (4) which is bent into a wave shape. <IMAGE>

Title: Float-type flow meter
Inventor: KOBOLD KLAUS DIPL ING
IPC: G01F1/22
Filed: 1983-11-17
Abstract: The invention relates to a float-type flow meter having a vertical, essentially tubular housing, through which the medium to be measured is to flow from the bottom to the top, and having a float which can be raised in a main flow channel, formed by the housing, by the flow of the medium, possibly against the action of a spring and possibly with continuous enlargement of a free flow cross-section, and is guided axially inside the housing. In order to reduce the influence of the temperature and thus viscosity of the medium to be measured, the float-type flow meter is distinguished by a bypass channel which connects the inlet and outlet of the housing, which are separate from the main flow channel accommodating the float, and which has a valve arrangement which opens the bypass channel below a prescribed temperature of the medium to be measured and closes it above a prescribed temperature of the medium to be measured.

Patent DE-3346012-A1 (DE)
Title: Method and device for stopping a DC intermediate-circuit converter
Inventor: HASHII MAKOTO DIPL ING
IPC: H02M7/515
Filed: 1983-12-20
Abstract: If it is desired to stop the converter in a converter having a current [sic] intermediate circuit, by reducing the frequency to zero, then the commutating capacitors must be adequately charged in the correct polarity for starting operation again. To this end, if the frequency falls below a predetermined frequency limit, on the one hand the intermediate circuit current is limited to a constantly predetermined value, and on the other hand the invertor is operated at an increased commutating frequency until a predetermined phase angle in the commutation cycle is reached. When this predetermined phase angle is reached, the commutation cycle is stopped and the converter is blocked. There is then so much energy stored in the invertor that the commutation cycle can be started again at any time at this predetermined phase angle. <IMAGE>

Patent DE-3425100-A1 (DE)
Title: Fitting for fixing the pivotable legs of folding tables in the end positions
Inventor: HILLER ROLF
IPC: A47B3/08
Filed: 1984-07-07
Abstract: To improve the standing rigidity of the pivoted-out legs of folding tables, the latch strut 5, the link rail 10 and leg columns 4 form, via the additional bearing 11, a closed triangle of forces which removes internal forces from the table top 1 and the attachments of pivot bearings 2 and link rail 10. The mushroom-shaped catch spring 12 in the form of a pressure point engagement takes on the securement of the pivoted-in legs against dropping out. The fitting contains devices for reducing noise in the form of a spring 15 or in the form of a twisting of the latch strut 5 produced by staggered guide grooves 8a. Together with the noise-reduction base 14 of the catch spring 12, the rattling of loose fitting parts during the actuation of the mechanism is ruled out due to tensioning. In the collapsed position, the individual parts of the catch mechanism are covered by the latch strut 5 which is pivoted in flatly above the link rail 10. <IMAGE>
Patent DE-3430730-A1 (DE)
Title: Detector for detecting the flow of a current through one or more conductors
Inventor: BALLADA ROMANO
IPC: G01R19/15
Filed: 1984-08-21
Abstract: The invention is concerned with a detector for detecting the flow of a current in conductors, to be precise by a toroidal-core transformer which detects the flowing of a current in a conductor and operates a signal generator if a preset threshold value for the current is exceeded. For this purpose, a first circuit, which has a rectifier which may be in connection with a voltage amplifier, a capacitor and a second circuit are provided between the transformer and the signal generator in such a way that a signal on the secondary side of the transformer effects a discharge of the capacitor via the first circuit upon reaching a suitable voltage value at the ends of the capacitor, which voltage value corresponds to the current value for which a detection is desired, the capacitor suddenly discharging via the second circuit to the signal generator.
Patent DE-3437000-A1 (DE)
Title: Sewage pipe with automatic return-flow barrier
Inventor: DALLMER JOHANNES ING GRAD
IPC: E03F7/04
Filed: 1984-10-09
Abstract: The sewage pipe has a housing with an inlet stub (11), an outlet stub (12) and a box-shaped upper housing part (10) which is located between the stubs and forms a cleaning opening shut off by a cover (15). In order to close the inlet stub, a flap (20) is attached which is held in a horizontal opening position by spring force. A rubber bubble which has a flat, plate-like form is fastened beneath the cover. The cover also receives a level regulator (35) with two electrodes which are located somewhat higher than the top of the outlet stub (12). In the case of return flow, water passes into the region of the electrodes and the regulator starts up an air supply to the bubble, with the result that the bubble inflates and pneumatically blocks off the through-passage cross-section for the return flow. At the same time, the bubble also presses the flap into its closed position. When the return flow eases off, the bubble is deflated, it assumes its flat shape, moves the flap automatically upwards and the through-passage is released. In addition, the flap can also be brought into its closed position by hand. <IMAGE>

Title: Pipe cleaning device with striking pins in the nozzle head for removing hard encrustations in pipelines
Inventor: SCHUBERT WERNER DR MED
IPC: B08B9/053
Filed: 1984-12-29
Abstract: A very effective process for removing hard interior deposits which are often deposited in a layered manner from industrial pipelines is striking. For this purpose a simple-to-produce device is described which can be employed efficiently and by remote control in pipelines and can be used analogously to the pipe cleaning tubes having a nozzle head at the front. The nozzle head contains, in its sturdily designed side wall, radial bores or sliding surfaces, arranged perpendicular to the longitudinal axis, for striking pins having a relatively broad baseplate which is also fitted in, so that upon application of intermittent fluid externally, striking actions, which are now controllable, can be achieved in the encrusted pipeline. Further tools such as a steel brush can simultaneously be moved by means of intermittent fluid laterally at the front of the nozzle head, longitudinally by means of a hydraulic cylinder or by means of a simple linear motor. By receiving the sound waves caused by the striking, a practised skilled worker can control this device externally and use it efficiently. Continuous fluid can also be used in a conventional manner for this device for advance or flushing and the like. A tool/tools such as one or more hammers simultaneously can be used with this device with intermittent fluid. <IMAGE>

Patent DE-3521246-A1 (DE)
Title: Elastic support
Inventor: LOCHNER KASPAR
IPC: F16F13/20
Filed: 1985-06-13
Abstract: The invention relates to an elastic support, in particular for internal combustion engines, with a carrying element and a supporting element between which are provided in parallel at least one rubber-elastic body and a hydraulic damping system. Known supports of this kind must be tuned exactly to the respective damping application and have the grave disadvantage of transmitting noise in the case of high-frequency small vibrations. According to the invention, this is avoided by the fact that a pneumatic bellows under a predetermined internal pressure is built into the hydraulic damping system in parallel with the rubber-elastic body and, in the support, the said bellows forms a softer spring than the rubber-elastic body and can be used to decouple, to a great extent at least, static loads to be transmitted from the carrying element to the supporting element from the rubber-elastic body. Since the pneumatic bellows removes a preload on the rubber-elastic body under the static load, the rubber-elastic body can absorb high-frequency small vibrations without transmitting noise. The support is universal in application since it can be adapted to different conditions by means of the internal pressure of the pneumatic bellows.

Title: Connection of two pipe ends by means of a corrugated pipe
Inventor: WINZEN WILFRIED DR ING DR
IPC: F01N13/18
Filed: 1985-07-24
Abstract: A connection is specified for the free ends of two pipes of a pipeline for hot media, especially the exhaust gas pipeline of motor vehicles, which free ends are aligned coaxially with respect to one another, by means of a corrugated pipe or bellows having cylindrical connecting ends, the pipe ends engaging over one another axially by means of inner protection pipes, inside the corrugated pipe, which are attached to said pipe ends or are integrally connected to them, and the cylindrical connecting ends of the corrugated pipe being connected at least indirectly, in a media-tight manner, to the pipe ends. At the same time, the arrangement is configured such that at least one of the welded connections of the ends of the corrugated pipe is separated from the wall part of the pipe end and inner protection pipe, which wall part is located radially inside and bounds the media, by means of at least one air gap or air intermediate space which forms a circumferential annulus.
Patent DE-3533656-A1 (DE)
Title: Top for a sanitary shut-off valve
Inventor: KRESS HERMANN
IPC: F16K47/02
Filed: 1985-09-20
Abstract: In a top part for a sanitary shut-off valve which, within a housing, comprises a fixed control disc and a control disc which can be rotated relative to the first control disc, the valve spindle is connected in terms of its drive to a motion brake. In this way, excessively fast turning of the rotatable control disc into the closed position, which could give rise to water hammer in the connected pipes, is prevented. The motion brake comprises a piston which moves backwards and forwards in an essentially closed space and divides this space into two subspaces. The subspaces are connected to one another via a displacement path. A viscous fluid medium fills the two subspaces of the essentially closed space and, when the piston moves, is forced backwards and forwards between these spaces. The motion brake can be designed as a lubricant pump which brings about forced lubrication in the gap between the two control discs. <IMAGE>
