Patent DE-3110046-A1 (DE)
Title: Electrical invertor circuit having self-commutation
Inventor: WINKLER JIRI DIPL ING
IPC: H02M5/45
Filed: 1981-03-16
Abstract: The invention relates to an electrical invertor circuit which is supplied from an electrical power source (1 DEG ), has self-commutation and contains a supply rectifier block (3 DEG ), an invertor block, a supply capacitor block (4 DEG ) and an auxiliary storage block (6 DEG ), as well as overshoot reactors (7 DEG , 8 DEG ), a recharging source, a block (9 DEG ) of commutation pulses and a recharging inductor (10 DEG ). For switching relatively low and medium power, three-stage commutation is used, the switching-off of the invertor thyristors and the current commutation being isolated in the phases, and the stored energy of the invertor capacitors being dissipated without losses into the electrical power source and thus into the invertor load. The invention can be used advantageously for both single-motor and multi-motor drives having asynchronous motors and synchronous motors and, furthermore, also for other types of load impedances. <IMAGE>

Title: Optical sensor arrangement
Inventor: EIFFERT KARL LUDWIG DIPL ING
IPC: G01B11/02
Filed: 1981-08-05
Abstract: The invention relates to an optical sensor arrangement for measuring displacement or the relative speed of a moving part (1), particularly of a magnetically supported rotor. According to the invention, one light source (6, 7) is in each case arranged oppositely located, for example at the front ends of the rotor, the light rays of which are incident on the reflection surfaces (2, 3) via lenses (22, 23) and are reflected from these surfaces to sensors (8, 9). The intensity of the light incident on the sensor is different depending on the distance of the respective reflection surfaces from the associated sensor. The output signal of the sensor, which is constructed, for example, as photo transistor, represents a measure of the distance or the displacement of the reflection surface. The signals of the oppositely located sensors are combined in a differentiating element (15). <IMAGE>

IPC: B65G65/06
Filed: 1981-08-29
Abstract: The invention relates to a device for recovering bulk materials, in particular from round bulk-material dumps, having at least one clearing dozer with which the stored bulk material can be drawn off on a discharger arranged in the centre of the bulk-material store. Arranged below the discharger is a conveying means via which the material can be led off from the region of the store surface. The clearing dozer is arranged in the region of the base of the bulk-material store on a hollow column, driven by a motor, with a vertical axis of rotation so that it can be pivoted with the column about the axis of rotation thereof. The discharger is located inside the column. Above the clearing dozer, the column is provided with a conical or frustoconical covering. The covering is preferably mounted so as to be rotatable on the column. The column can be extended up to beyond the highest level of the bulk material and can bear at its upper end a tipper which is rotatable relative to the column. With such an extended column, a tubular casing is preferably mounted rotatably on the column, which tubular casing surrounds the column on the outside with spacing. Additionally, a clearing dozer is expediently provided, which conveys essentially radially inwards and extends essentially over the radius of the base of the conical dump. This clearing dozer can be supported at least partially directly or indirectly on the column. However, it can also be arranged on a full or half portal which is rotatable about the axis of the column. A clearing wheel can be provided on the column as the clearing dozer. However, operation can also take place with an essentially radially extending spiral conveyor or with an essentially radially extending scraper. If a clearing wheel is used, the latter can be attached to the column with spacing therefrom, an intermediate conveyor which is located below the covering then being arranged between the clearing wheel and the discharger in the column. <IMAGE>

Title: Aeration and ventilation device with recovery of the outgoing-air heat
Inventor: RAETZKE URSULA
IPC: F24F12/00
Filed: 1982-03-04
Abstract: The invention describes an aeration and ventilation device with recovery of the outgoing-air heat for living rooms and lounges, two radial blowers (10, 11) being provided for the separate supply and removal of the air flows. An accumulator pack (2, 3) is in each case used as a heat exchanger for incoming air and outgoing air. The sheets (4) of the accumulator packs (2, 3) are, according to switching position, in direct contact with the incoming air or the outgoing air. The change of direction of the air flows according to the thermal state of the accumulator packs (2, 3), with continuously operating radial blowers (10, 11), takes place via a drivable air flap (8). Constant changes of the speed vector of the air flows inside the accumulator packs (2, 3, 4) in the boundary layer region lead to an improvement in the heat transfer between the accumulator packs (2, 3) and the air flows. <IMAGE>

Title: Multi-channel, combination, directional antenna having dipoles loaded with reactances
Inventor: LINDENMEIER HEINZ PROF DR ING
IPC: H01Q5/49
Filed: 1982-03-15
Abstract: The invention relates to a dipole antenna array which is preferably used as an end-fire array for the reception of broadcast radio and television transmissions. With the exception of the dipole containing the antenna connecting point, the dipoles of the antenna are connected individually or all together to interruption points, by means of frequency-dependent complex impedances. The spatial arrangement of the dipoles and of the interruption points on said dipole are suitably defined and the frequency-dependent complex impedances are implemented in such a manner that the antenna in each case has a virtually maximum directional effect which can be achieved with the specified array arrangement in at least two frequency channels, which are separated in terms of frequency, in one predetermined spatial direction. A significantly smaller directional effect and front-to-back ratio are obtained in this case in the frequency band between the frequency channels. The complex impedances, which as a rule consist of low-loss reactive elements, are preferably constructed such that the reactance level and the number and frequency positions of the poles and null points of the reactance functions of these circuits are selected in such a manner that the desired directional effect is obtained in the frequency channels. The reactive elements are preferably implemented by printed circuits whose artworks are produced with the aid of a digital computer installation.

Filed: 1982-09-30
Abstract: A logic card comprises a printed circuitboard equipped with integrated modules, a plug connector and a contact pressure component, for example, a cooling device, which exerts a pressure against a surface of the printed circuitboard. In order to prevent sag of the printed circuitboard which could result by the contact pressure component, or to prevent line ruptures and the like caused by plug-in and pulling events, a counterpressure is generated against the printed circuitboard and an elastic connection is produced between the plug connector and the printed circuitboard. To this end, the contacting elements of the plug connector are uniformly, planarly distributed over the printed circuitboard. Each comprises a spring shank for receiving a contact pin and a terminal lug for resiliently pressing against the printed circuitboard.

Filed: 1983-02-09
Abstract: An axial fan is described, especially for the cooler of a water-cooled internal combustion engine for commercial vehicles, which comprises a hub with fan blades and an air duct device enclosing this, which widens towards the outlet area. The widening begins in the area of the intake edge of the fan blades and the external contour of the fan blades is adapted to match the internal contour of the air duct device. The air duct device is at the same time designed as a fixed fan body, inside which the fan blades rotate. In another embodiment the air duct device forms part of the fan wheel comprising the hub and the fan blades and is connected fixedly to the ends of the fan blades as a ducting ring. A further variant provides for the attachment of an annular disc to the hub in the area of the outlet edge of the fan blades, the diameter of which disc is at least 30% greater than the hub diameter. All these measures contribute to a reduction in the noise level of the axial fan.
