Patent DE-3502932-A1 (DE)
Title: Automatic transmission for motor vehicles
Inventor: NITESCU GHEORGHE PROF DR
IPC: F16H3/66
Filed: 1985-01-30
Abstract: The automatic transmission for motor vehicles has a hydrodynamic torque converter (2) driven by an input shaft (5) and consisting of a pump impeller (6), a turbine rotor (7) and a stator (8), a multi-speed planetary gear set (4) with shifting elements which can be actuated to engage the individual gear stages, and a planetary power divider (3) which is connected to the input of the planetary gear set and, for its part, has a first input (14), connected to the input shaft, and a second input (13), connected to a turbine shaft (12) connected to the turbine rotor (7) of the torque converter (2). In order to achieve a wider range with a larger number of gears in a transmission arrangement of this kind, the planetary power divider (3) is to be designed to provide an additional transmission stage in at least one of the gear stages of the planetary gear set (4). This is accomplished by the fact that at least one of the inputs, preferably the first input, formed by the ring gear (14), of the planetary power divider (3) can be separated by a clutch (17) from the shaft (11) connected to it and can be fixed by a braking device (18). <IMAGE>
Patent DE-3503232-A1 (DE)
Title: Method of controlling a strip having a magnetic toting, in particular an audio or a data tape, and an apparatus for carrying out the method
Inventor: MOSER CHRISTIAN
IPC: G11B15/02
Filed: 1985-01-31
Abstract: The method and the apparatus are used for controlling or precisely setting a read head with respect to an audio or data tape in order to prevent dropouts of individual syllables or data owing to tape displacement. This is particularly important for example in the case of repeated broadcasts of information in air traffic or in the transmission of data. A further area of application is the protection of bank information, in order to ensure that it is retained strictly and is not passed on to unauthorised persons. For accurate setting of the read head with respect to the tape, provided with two or more tracks, a correction of the tape position is carried out by means of one track, for example for every 500th oscillation. For this purpose, use is made, inter alia, of a counter and of a frequency or phase change, which ensure a correct setting. Set up in this way, the apparatus is easy to operate to carry out the method and requires virtually no initial instruction. <IMAGE>

Title: Optical probe device for photometric analysis of fluids flowing in lines
Inventor: RIESS SIEGFRIED
IPC: G01N21/53
Filed: 1985-02-02
Abstract: The invention makes it possible to design an optical probe device in such a way that it causes only a small pressure drop in the associated line section, that it is easy to clean, particularly with throughflow, and that it permits the measurements of high turbidities of the fluid to be analysed under constant measurement conditions. These advantages are achieved, inter alia, by a measuring duct running parallel to the axis of the line section being formed in the bottom of the probe device housing, and by providing an optical path which crosses the measuring duct only once (Figure 1). <IMAGE>

Patent DE-3505737-A1 (DE)
Title: Electrical installation switch
Inventor: WITTWER GUENTER
IPC: H01H23/00
Filed: 1985-02-20
Abstract: The invention relates to an electrical installation switch, by means of which it is possible to carry out two different switching functions, specifically the rocker-switch function and the push-button switch function. To this end, a switching segment in the form of an angle and a pivoting shaft for support in a supporting plate are located on the underneath of an operating device. The switching segment is constructed in the form of an angle and has a straight limb which points downwards and on which a second is integrally formed in a bent manner. Depending on the intended switching function, one limb or the other is operatively connected to a U-bracket which is supported on a switch housing such that it can pivot and which, during a switching operation, operates a sprung switching plunger on the switch housing. The change in function is in each case carried out by releasing the operating device from the supporting plate, rotating the operating device through 180 DEG , and subsequently inserting it into the supporting plate again. This rotation results in either the straight limb or the bent limb interacting in a specified manner with the U-bracket in order to carry out the selected switching function. No structural changes are required for carrying out the one switching function or the other.

Patent DE-3525313-A1 (DE)
Title: Degassing valve for a container seal
IPC: F15B21/044
Filed: 1985-07-16
Abstract: In containers intended for liquids it is often required that the container seal have a degassing valve in order to prevent a damaging excess pressure from arising, that is, in order to enable air or gases to escape to the outside. The degassing valve comprises a diaphragm which is only permeable to air and which repels liquids and does not allow them to pass. To protect the diaphragm against the damaging effect of the liquid, which attacks the diaphragm in a disadvantageous manner over a prolonged period and destroys it, the diaphragm is arranged inside a protective holder which consists of a cap and a diaphragm support located inside the cap. The diaphragm itself is held between the cap and the diaphragm support by clamping. The protective holder has an inlet opening inside the cap and an outlet opening in aligment with it inside the diaphragm support. The inlet opening is selected to be so small that no liquid can pass through it to the diaphragm.

Patent DE-3530738-A1 (DE)
Title: Device for controlling polarisation
Inventor: NOE REINHOLD DIPL ING
IPC: G02F1/01
Filed: 1985-08-28
Abstract: Particularly in the case of optical heterodyne receivers, there is the problem that before the superposition of the received light and the light generated in a local laser it is necessary to bring the polarisations of the two into agreement. This requires an arrangement for controlling polarisation which compensates temporal variations in the polarisation without the occurrence of variations in optical intensity, and thus without signal failures, during the control process. For this purpose, five elements are provided which have adjustable birefringence and are realised, for example, by relays whose movable armatures exert a more or less intense pressure on an optical fibre having a circular cross-section. <IMAGE>

Title: Arrangement for regulating a motor
Inventor: BECKER GERHARD
IPC: H02P27/02
Filed: 1985-09-18
Abstract: The current regulation for the windings (1, 2, 3) of a motor is carried out by coarse regulation using a two-point regulator (5, 11), and fine regulation using a PI regulator (8, 15). Fine regulation is in this case switched to two-point regulation as a regulating variable. This current regulation is carried out in an identical manner for both windings (1, 2) of the asynchronous motor. The third winding (3) of the asynchronous motor is regulated by means of two-point regulation, using evaluation of the control errors (A, B) of the PI regulators (8, 15) of the other motor windings (1, 2), and evaluation of an actual value sum signal (14) from the two other motor windings (1, 2). <IMAGE>

Patent DE-3544101-A1 (DE)
Title: Infrared coagulator
Inventor: LAMPE GERHARD
IPC: A01M21/04
Filed: 1985-12-13
Abstract: Weeds are predominantly removed with the aid of pesticides in agriculture and horticulture. The negative consequences are known. Attempts to use gas-fired flame throwers for removing weeds are certainly a step in the right direction, but they are excessively expensive in terms of energy and time. The infrared coagulator adopts a new approach. It permits infrared radiation to be used to coagulate the protein in the leaves of weeds and thereby causes them to die.

Title: Valve for controlling a hydraulic cylinder, in particular in shield-type support in mining
Inventor: MATEJA ERNST DIPL ING
IPC: E21D23/16
Filed: 1986-11-14
Abstract: A valve for controlling a hydraulic cylinder, in particular in shield-type support in mining, has in a housing body (1) a closing body (7) which is acted upon by a spring (13) at its rear side and by the hydraulic pressure in the closed position. The closing body (7) can be lifted from its sealing seat (6) by means of a plunger (34) directed towards its front side and sitting on a piston (31). The piston (31) has an axial passage leading to a return line (28) for the hydraulic medium and is actuated by means of a further piston (38) closing the passage in the process. The closing body (7) also has an axial passage (8) which can be closed by a further closing body (18) acted upon by a spring (18) at its rear side and by the hydraulic pressure in the closed position. This further closing body (18) can be lifted from its sealing seat before the first-mentioned closing body (7) by means of the said plunger (34) via a bolt (19) projecting through the passage (8). The advanced lifting of the further closing body, especially together with further measures, leads to a reduction in the hydraulic pressure on the closing body so that it is easier to lift the latter. <IMAGE>
