Patent DE-3738925-A1 (DE)
Title: Segmental orifice plate for through-flow control and through-flow measurement of a pulsating intake air current on an internal combustion engine
Inventor: WALDHELM FERD DIPL ING
IPC: F02D11/10
Filed: 1987-11-17
Abstract: Instead of the otherwise customary throttle valve for intake air through-flow control on an internal combustion engine, a segmental orifice plate is used which also at the same time permits through-flow measurement of the intake air. The through-flow value is determined from the sensor signal for the difference in pressure and from the segmental orifice plate position signal in conjunction with a microcomputer. In this, the other signal inputs of the microcomputer are taken into account by means of sensors for absolute pressure, temperature and possibly also moisture for determining the density of the intake air.   The segmental orifice plate drive consists of two drive levers which are rotatably mounted on the drive axle and, moved in parallel, guide the segmental orifice plate, mounted at their end, in a seal on each side. In the event of pulsations of the intake air, the measuring principle permits the return flow to be determined by technical measuring means and to be eliminated during the evaluation of the through-flow measurement.

Title: Locking of the piston rod within a cylinder
Inventor: LEHR ADOLF DIPL ING
IPC: F15B15/26
Filed: 1987-11-28
Abstract: The invention relates to a locking of the piston rod within a cylinder for a hydraulic chucking device and for the chucking of workpieces, shapes and the like on machine tables. A clamping device is arranged movably within a housing. The clamping device possesses different bores, one matched to the diameter of the piston and one to the diameter of the piston rod. The clamping device is widened conically at its end relative to the piston rod, and seated on the piston rod is a wedge, the outer face of which is made conical and is matched to the widened cone. This wedge is provided with slots and can therefore be pressed onto the piston rod. This pressing-on takes place by sliding the conical faces of the clamping device and of the wedge on one another, as a result of which a pressure acting perpendicularly to the movement is also exerted on the wedge. The locking device takes effect irrespective of incorrect operations and can be released for loading with compressed air by means of two pulses transmitted simultaneously.

Title: Motor-driven chiselling or drilling hammer
Inventor: WANNER KARL DR DR ING
IPC: B25D11/12
Filed: 1987-12-21
Abstract: For aeration and deaeration of the piston space (8) during the no-load operation of a chiselling or drilling hammer, the piston (5) has a lateral air passage (10) and the hammer tube (14) has an air passage (18). During the transition into the no-load operation, the hammer tube (14) is displaced axially towards the tool holder (3) and simultaneously turned, so that the air passages (10 and 18) coincide. The turning of the hammer tube (14) is effected by a bolt (21) which is fixed therein and is guided in a groove (22) in the housing (1), running obliquely to the axis of the percussion mechanism. As a result of the turning of the hammer tube (14), a considerable shortening of the no-load travel is achieved, thus making the hammer much more user-friendly. In no-load operation, the percussion member (11) is held in the space (33) in a manner free from wear by means of an air spring. <IMAGE>

Title: Method for protecting IR-detectors against laser radiation
Inventor: ARNOLD MICHAEL DIPL PHYS DR
IPC: H01L31/0232
Filed: 1988-02-12
Abstract: A method which protects IR-detectors against intensive laser radiation, in that radiation above an intensity threshold value is at least weakened by means of an optical device arranged in the beam passage direction in front of the detector. Here, in order to achieve an improvement of the protection function above all for short laser pulses of higher intensity and for long pulses or continuous-wave operation at lower intensities, the protection-triggering mechanism is brought about by means of at least two different devices, inserted in the manner of a cascade circuit into the beam path and having different insertion thresholds and reaction times either passively, i.e. simply by internal interaction of the radiation with the optical material of the device, or actively, i.e. by means of external physical effects on the material of the devices.

Title: Rotation viscometer
Inventor: KAERMER REINHARD DIPL ING DR
IPC: G01N11/14
Filed: 1988-08-02
Abstract: The invention relates to a rotation viscometer having an extended range of application for the determination of the flow properties of flowable media, especially fluids which are used as output products and intermediate products during processing in spinning processes, coating processes and other shaping processes in the material conversion industry. The inner cylinder of the rotation viscometer is formed as a stationary test body and is arranged so as to be able to be displaced in the axial direction relative to the rotating outer cylinder. Both the cylindrical and also an additional shearing gap, which is between the end of the test body and the bottom of the outer cylinder and can be varied in its thickness, are connected to a pressure measuring device via a chamber arranged in the inner cylinder. The rotational movement of the outer cylinder acts against the measuring torque caused by the medium and the device dimensioning, the torque being detected and fed to a converter as information about the purely viscous properties of the material being measured. At the same time, by means of the shear in the additional shear gap, a pressure difference between the free surroundings and a measuring chamber is brought about, which is used with a pressure measuring device for determining the elastic properties of the fluid.
