Patent DE-3742241-A1 (DE)
Title: Piezocontrol valve for controlling fuel injection via an injection valve in internal combustion engines
Inventor: SCHWERDT PAUL
IPC: F02M51/00
Filed: 1987-12-12
Abstract: A piezocontrol valve, in particular for controlling fuel injection by means of an injection valve is described, which consists of a piezoactuator which is arranged in a housing and a valve. By means of a hydraulic play compensating element within the control valve, on the one hand, possible changes in length of the reference system are automatically compensated as a result of piezoceramic creep processes in the piezoactuator so that with the same working stroke of the piezoactuator an identical stroke at the valve is also always ensured. In addition, by means of hydraulic stroke transmission within the control valve, on the other hand, a valve stroke which corresponds to a multiple of the working stroke is achieved.

Title: Circuit for controlling the luminous flux of fluorescent lamps
Inventor: MALY JAN DIPL ING
IPC: H05B41/392
Filed: 1988-04-12
Abstract: The invention relates to lighting technology and can be used in different branches of the national economy, such as for example in agriculture, in the health service etc. The circuit under consideration solves a continuous control of the luminous flux of fluorescent lamps in applications where the use of existing illumination systems is not advantageous, or where in some cases it is even impossible to use them because the animals shy (for example in large-scale breeding of commercial stock which due to the flashing of fluorescent lamps become restless). The invention consists in connecting, on the one hand, the circuit 60 and, on the other hand, the pulse generator 90 in parallel with the fluorescent tube element 5. The output 91 of the pulse generator 90 is in this case connected to the control input 61 of the circuit 60. <IMAGE>

The second limbs (20, 21) which face away from one another contain openings (24) for accommodating guide bolts (80) which are intended for cabinet mounting. The mounting rack is preferably suitable for use in cable television installations. The drawing shows a perspective view of a mounting rack which is fitted with assemblies and is intended for wall mounting. <IMAGE>

Title: Method and appliance for switching a burner on or off
Inventor: SCHUMACHER KLAUS DIPL ING
IPC: F23K5/00
Filed: 1988-07-28
Abstract: The invention relates to a method for switching a burner on or off. If a burner is switched on or off simply by opening or interrupting its combustion gas (fuel gas) supply, undesirable processes may take place in the turning-on and turning-off phase, e.g. flash-backs in the case of turning off, or flames being produced in unpredictable ways in the case of ignition. In order to achieve controlled turning-on and turning-off operations it is therefore proposed that, for the purpose of turning-on and/or turning-off the burner, there is introduced, into the supply lines equipped with a non-return valve and downstream thereof, an inert gas in such a way that the inert gas has a higher pressure than the combustion gas supplied in the supply line in question. According to this method, when the burner is turned on, the inert gas supply is terminated after a short time and the combustion gases then flowing are ignited, and when the burner is turned off, the inert gas flow through the burner is terminated after the flame has gone out.

Title: Fluid coupling
Inventor: HAYASHI MASAHARU
IPC: F16D35/02
Filed: 1988-09-28
Abstract: A fluid coupling comprises three-stage control of torque transmission. The coupling has two slots (11, 13). One slot (13) is opened when the temperature reaches a first set value. The other slot (11) is opened when the temperature reaches the second set value. The latter slot (11) has a shape, the opening of which gradually rises in accordance with the movement of a valve element (15), with the result that the torque transmitted rises gradually from the second torque transmission condition to a third torque transmission condition. <IMAGE>

Filed: 1989-03-30
Abstract: The invention relates to an arrangement for light detection in a light scanning microscope. Preferred area of application are the variants of the light scanning microscopy, in which the available amount of light is limited and a minimum constructional size of the arrangement is important. In the arrangement, the photodetector 4 and/or 5 is designed as a component 3 or 10 (a diaphragm) which constricts the light flux of the primary light through the optics 2 or is connected to such a component. The result of coupling diaphragm 3 or 10 and photodetector 4 or 5 is, that the highly-corrected central part of the optics 2 is still available with the full transparency. <IMAGE>

Title: Measuring path differences of anisotropic transparent objects - using circular polarisation device with second quarter wave retarder replaceable by compensator
Inventor: BERGNER JOACHIM
IPC: G01N21/21
Filed: 1989-09-07
Abstract: An object (O) is arranged with any orientation of its main oscillation directions in a circular polarisation device after a first quarter wave retarder (Q1).  The polarisation device consists of two parallel linear polarising elements and two, pref. achromatic, quarter wave retarders lying between them.  The oscillation ellipse of the object is rotated until maximum contrast is reached. A second retarder (Q2) is then exchanged for a compensator (K) with its main oscillation direction at 45 deg. to the polar retarder oscillation directions and with a measurable, variable path difference.  The object's ellipse is rotated by 45 deg. so that its oscillation direction coincides with that of the compensator and the compensation device operated to null the object path difference which can then be derived. ADVANTAGE - Measures path differences of anisotropic transparent objects with any azimuthal orientation and path difference magnitude.

Patent DE-3934974-A1 (DE)
Inventor: PRZYBYLA BERND ING GRAD
IPC: G01R31/00
Filed: 1989-10-20
Abstract: A device is useful for monitoring the functions of a plurality of control units (10-13) in a motor vehicle by means of a single control display (20). Each control unit (10-13) comprises means for generating a control signal as a function identification, from which data for triggering the control display (20) are derived. The control units (10-13) are interconnected by at least one diagnostic and/or bus line (16, 17, 30). The control signals can be transferred to the control unit (10) by the switching means for triggering the control display (20) and the signal for the control display (20) can be influenced in function of these control signals. Hence, only one control display (20) is required and switching means (18) are required in only one control unit (10-13). As the existing diagnostic and/or communication lines (16, 17, 30) are used, minimal additional hardware is necessary even when a large number of control units (10-13) are to be monitored.
