Patent DE-3521519-A1 (DE)
Title: Power converter circuit
Inventor: KNAPP PETER DIPL ING
IPC: H02M1/12
Filed: 1985-06-15
Abstract: Undesirable network interference occurs when operating power converters (4, 5), as a result of harmonics. Power converter circuits are specified in the case of which, using one or two additional AC sources (Q), approximately the same reduction in the harmonic content can be achieved as in the case of a converter circuit having double the number of poles P. The frequency of the additional AC source (Q) is selected to be equal to fN.p/2, while fN = frequency of the alternating current which supplies the power converter (4, 5). The additional DC source (Q) with an impressed additional AC component (ih) is connected in parallel with an inductor (6) via whose centre tap a load (L) is connected to neutral conductors (N2, N3) of transformer secondary windings (2, 3). <IMAGE>
Patent DE-3522443-A1 (DE)
Title: Solid laser or solid laser amplifier having a slab as the active medium
Inventor: EICHER JOCHEN DIPL PHYS
IPC: H01S3/02
Filed: 1985-06-22
Abstract: In zigzag slab-laser systems, high beam qualities with respect to the local structure and beam divergence, and hence high power densities at the focus can be achieved if the slab is homogeneously optically pumped and cooled by the polished side surfaces. This is achieved by means of combined gas-liquid cooling, the slab being located in a special slab holder between two pumping chambers which contain the flashlamps. In this arrangement, the slab holder makes possible stress-free attachment of the slab and, at the same time, efficient and homogeneous cooling of the active medium by means of cooling-gas layers of minimum thickness between the slab side surfaces and the liquid-cooled optical side windows. The sandwich construction of the laser head having two pumping chambers on both sides of the slab holder result in high flexibility and maintainability of the system. The special liquid circuit in the pump chambers ensures effective and uniform cooling of the flashlamps, slab, reflectors and housing. A long life of the flashlamps inter alia, is thus also achieved as well as homogenous cooling of the slab.

Title: Device for controlling the amounts of exhaust gas recirculated in internal combustion engines
Inventor: MAISCH WOLFGANG DIPL ING DR
IPC: F02M25/07
Filed: 1985-07-23
Abstract: A device is proposed which serves for controlling the amount of exhaust gas recirculated to the intake side by the exhaust system of an internal combustion engine. The device comprises a pneumatically functioning control element (9) with a diaphragm (8) defining a working chamber (11), which diaphragm actuates a valve closing element (7) of an exhaust recirculation valve (6). By way of a control pressure line (14) a flow line (15) to the atmosphere and a connecting line (17) to the intake pipe (2) downstream of a throttle valve (5) are connected to the working chamber (11). A non-return valve (18) opening towards the intake pipe, an accumulator (20) and a restrictor (19) are arranged in the connecting line (17). A bypass line (21) with a bypass valve (22) designed as electro-fluid converter of the nozzle-deflection plate type bypasses the restrictor (19). In the flow line (15) a control valve (16), likewise designed as an electro-fluid converter of the nozzle-deflection plate type, is arranged, by means of which a certain pressure drop between the atmosphere and the pressure in the working chamber (11) can be set, controlled by an electronic control device (23) as a function of characteristic operating variables of the internal combustion engine.   <IMAGE>

Title: Light guide connector having a central guide at least of the core of a light guide
Inventor: SCHOCH JAKOB
IPC: G02B6/38
Filed: 1985-09-19
Abstract: The connector is distinguished by two clamping devices each having a collet (26, 16). The front collet (26) is inserted into a cap (27), and the jaws (162) of the second collet (16) are located in the bore of an inner sleeve (14). The shaft (264) of the front collet (26) is plugged from the front into the inner sleeve (14), and the jaws (261) are situated with their cams (263) on the end face (144) of the inner sleeve (14). The result of axially displacing the cap (27) is firstly to bring the front collet (26) into pressing position, and given further pressure the inner sleeve (14) is pushed onto the second collet (16) which is thereby likewise brought into pressing position. As a result, an optical fibre can be clamped in place on the mechanical protective cover, in order in this way to centre the fibre in the connector. In addition, the core is simultaneously centered and fixed. Due to the flat end face (276) of the cap (27), the core can easily be ground flat, and no abrasive flour can penetrated into the rear parts of the connector and possibly impair the function. <IMAGE>

Title: Device for driving dowels into dowel holes of workpieces
Inventor: HOFFMANN HERBERT
IPC: B25C1/04
Filed: 1986-01-29
Abstract: The device has a ram (11) which is movable along a guide and is intended for driving in each case one dowel fed by a dowel-feeding device individually in front of the ram out through a driving-out opening (17). The driving-out position of the ram is defined by one of the end positions of the piston (13) such that the ram end is flush with the driving-out opening of the dowel guide or at a precisely defined distance from this driving-out opening. The ram is assigned a centring pin (20) which is guided coaxially with the latter and in the driving-out position of the ram protrudes from the driving-out opening (17) of the dowel guide with its pin end (23) remote from the piston (13) and is axially movable by a dimension which is at least equal to the distance of the pin end (23), remote from the piston, from the front ram end when the ram is in the driving-out position. The device makes it possible to drive dowels into receiving holes of workpieces in a flush manner or protruding from the surface of the workpiece by a predetermined dimension. <IMAGE>

Title: Wiping device for windows and headlight lenses for motor vehicles
Inventor: KUEHBAUCH GERD DIPL ING
IPC: B60S1/08
Filed: 1986-06-13
Abstract: A device is proposed which serves for wiping windows and headlight lenses on motor vehicles. The wiping device comprises an elongate wiper arm which is driven in an oscillating fashion by an electric drive motor via an oscillating gear mechanism and on its end which is remote from the oscillating spindle there is arranged a wiping element lying on the windows and headlight lens. The wiper arm has a guide piece which is penetrated by the oscillating spindle and on which a lifting element is guided displaceably in the longitudinal direction of the wiper arm and carries the wiping element. The lifting element is fed a lifting motion derived from the flow of motion from the drive motor to the wiper arm. A compact wiping device with a simple body, which can be easily seen over, and with a high degree of efficiency results if the drive motor is arranged on the guide piece of the wiper arm and to produce the oscillating movement interacts via gear means, which are driven by it, with gear means which are fixed to the vehicle body. A further particular advantage of this arrangement is the uncomplicated layout of the device in accordance with the particular customer requirements which owing to the different shapes of the window and headlight lenses to be wiped are extremely diverse. <IMAGE>

Title: Electric motor having a housing and an armature shaft
Inventor: BOHN ROLAND DIPL ING
IPC: H02K5/167
Filed: 1987-01-14
Abstract: An electric motor is proposed which is used for adjusting devices, especially headlights (head lamps) on motor vehicles. For this purpose, the motor is frequently accommodated at points which are subjected to intensive water spray. The electric motor comprises a housing and an armature shaft which are preferably connected at their output-drive end to a step-down transmission and whose other end passes through a bearing plate, which belongs to the motor housing and supports the armature shaft, in a central recess. This end of the armature shaft which is located outside the motor housing has a handle for manual rotation of the armature shaft, so that, in an emergency, the device can be adjusted by hand in the necessary manner if the electric motor fails. In order that the central recess in the bearing plate is protected against water spray, which central recess can be sealed only at great expense and through which the armature shaft passes, the central recess is located closer to this end of the armature shaft than the outer edge region (which is connected to the further housing parts) of the bearing plate, and the handle (which is preferably constructed in the form of a pot) engages over the bell-shaped region of the bearing plate thus formed. <IMAGE>
