Patent DE-4314147-A1 (DE)
Title: Machine tool esp. lathe - has motorised linear movement drive for headstock located movable in bed guide in housing provided with mounting for centring tip and signal transmitter for controlling linear movement
Inventor: BINDER ROBERT ING
IPC: B23Q17/00
Filed: 1993-04-29
Abstract: The linear movement drive is controlled depending on the pressure loading of the centring tip (9). The mounting (8) for the centring tip is either arranged in an axial direction at a force pick-up in the headstock housing (7), or the headstock (2) is supported at a force pickup for axial pressure forces. The pickup is arranged in the drive connection between the headstock (2) and the motor (3) of the linear drive (5). The force pickup as a signal transmitter is connected to the actual value input (17) of a regulating unit (18). The regulating unit controls the linear drive (5) depending on the difference between the specified desired value input (19) and the actual value input (17). This actual value of the axial pressure loading of the mounting (8) for the centring tip, is determined across the signal transmitter. ADVANTAGE - Simple construction so that specified adjusting force of centring tip at workpiece can be ensured, independent of outside interference. Gives exact and stable workpiece location.

Patent DE-4337150-A1 (DE)
Title: Process for carrying out ships' engine standing tests by means of a braking wheel
Inventor: BEGLER WOLFGANG
IPC: G01L3/16
Filed: 1993-10-30
Abstract: In the case of engine standing tests on ships, which are carried out in the fitting-out dock, a hydrodynamically acting braking wheel is used to load the drive engine installation instead of the propeller, to avoid propeller thrust and the propeller jet. A braking wheel which has previously been able to be used only for a previously calculated torque-rotational speed characteristic curve because of the hydrodynamic dependency, is designed according to the invention in such a way that the hydrodynamic braking covers only part of the required power and the remaining part is provided by a controllable braking system, in order to be able to use the braking wheel in a wide torque-rotational speed range. For the purpose of ensuring the dissipation of heat it is advantageous to arrange the controllable braking system as a mechanical friction brake on the circumference of the braking wheel. Water pressure or air pressure from the on-board mains is expediently used as the effective force for this brake.
Patent DE-4337827-A1 (DE)
Title: Device for tensioning a camshaft drive
Inventor: TRZMIEL ALFRED DIPL ING
IPC: F02B67/06
Filed: 1993-11-05
Abstract: The camshaft drive of the device has two camshafts, connected to one another by means of an endless drive, and two tensioning shoes which bear against the inside of each strand of the endless drive and are fastened to a piston in each case. At least one of these pistons is acted upon by hydraulic medium for the purpose of tensioning the endless drive of the camshaft. The design of the camshafts leads to accelerations and decelerations in the loose strand and in the stressed strand of the endless drive, which accelerations and decelerations result in the endless drive slackening and hence in the components being subject to a high degree of wear. In order to avoid premature wear of the parts of the device, the two pistons are mounted in an elastically compliant manner counter to the tensioning force. This double-action design prevents slackening in the endless drive and hence wear of the primary-side drive element. The device is suitable for use in motor vehicles.

Patent DE-4411127-A1 (DE)
Title: Ceramic substrate, and process for the production thereof
Inventor: YAMADE YOSHIAKI
IPC: C03C10/08
Filed: 1994-03-30
Abstract: The ceramic substrate comprising a glass and a crystal is characterised in that the glass comprises a glass based on MgO-Al2O3-SiO2-B2O3-R2O (R = alkali metal) and contains, as crystal, a 2MgO.2Al2O3.5SiO2 crystal (cordierite). As a consequence of the composition, the softening point of the glass is lower than 720 DEG C, and the porosity drops so that the substrate can be impermeable. As a result thereof, the coefficient of thermal expansion can be close to that of silicon, the specific induction capacity can be low and the substrate can be excellent with respect to transverse strength, moisture resistance, water resistance, etc. As a consequence of the reduced softening point, a ceramic substrate having the above properties can be produced even by sintering between 800 DEG C and 1000 DEG C, and a ceramic substrate having an internal circuit interconnection produced from Ag or Cu etc. can be produced.

Abstract: In a process controller 32 for on-line control of a printing press, a feedforward process control model 52 which controls the process is only updated if a disparity between the desired and actual process results 44, 48 is not due to a known cause or condition 78, 46, 82, 84.

Inventor: KLEINHANS JOSEF
IPC: G01F1/68
Filed: 1987-01-16
Abstract: Process and circuit for measuring the air flow in the inlet manifold (100) of an internal combustion engine. In order to obtain an output signal which can easily be processed in digital control devices, the diagonal voltage of a measurement bridge (RH, RK, RM, RZ), which is thermally coupled with a flow measurement unit (RS), is applied after possible amplification to a voltage-frequency converter (20), the output of which provides a frequency which is proportional to the diagonal voltage of the bridge circuit and is available for further processing. At the same time, this frequency is used for triggering a monostable trigger circuit (5) which cyclically connects the flow measurement unit (RS) with a voltage source (6).
