Patent DE-3810805-C1 (DE)
Title: Cooling device
IPC: B60K17/02
Filed: 1988-03-30
Granted: 1989-05-18
Abstract: A cooling device for clutches has air inlet and air outlet openings in the clutch housing, these openings being fitted with deflection devices which divert the cooling air from an axial direction at the air inlet into the circumferential direction of the rotating parts of the clutch and vice versa. The cooling air is conveyed through the clutch housing by exchange of momentum between the vortices that form at the uneven surface of the clutch disc and the flow at the guiding devices. This exchange of momentum furthermore has the effect of better cooling of the clutch components owing to better heat transfer.
Patent DE-3817416-C1 (DE)
IPC: D03D39/16
Filed: 1988-05-21
Granted: 1989-07-06
Abstract: In a double lift open shed Jacquard machine (4) for a double shed loom (1) comprising a reading-in mechanism (8) for program carriers (12) and a shed forming mechanism with double roller means (25) which after each reading-in operation can be positioned in three positions, a respective harness (5) and two control units comprising for example thrust needles (11), main needle (18) and hooks (20), operatively associated with each double roller means (25) and arranged in rows in juxtaposed relationship, in superposed relationship and in succession in the warp direction, the distribution of the control units (11, 18, 20) in relation to the width and the longitudinal direction of the machine is such that the number of juxtaposed rows of control units is substantially reduced, preferably halved, in relation to the number of juxtaposed rows of control units in a conventional Jacquard machine of that kind while the number of rows of control units arranged in succession in the longitudinal direction of the Jacquard machine (4) is correspondingly increased. <IMAGE>
Patent DE-3820206-C1 (DE)
Title: Process for monitoring of automatically operated plate filter presses
IPC: B01D25/00
Filed: 1988-06-14
Granted: 1989-08-10
Abstract: Operatives have previously monitored the operation of the filter press and only intervened if the filter cake is not correctly discharged or transport of the filter plate is disturbed. According to the invention, the operatives' workload can be reduced by furnishing the filter press with a transit control mounted beneath the filter plates and a time scanner corresponding to the opening cycle of the filter plates. If the transit control does not receive a pulse within the time scan, an alarm is triggered and/or the transport mechanism is stopped. Furthermore, the transit control is made dependent on the transport verification. The transport verification can also receive a time scanner which triggers an alarm and/or terminates the transport if the transport fails.

IPC: F01D5/04
Filed: 1989-03-14
Granted: 1990-06-07
Abstract: In a turbine wheel of an exhaust turbocharger for an internal combustion engine with radial and/or mixed-flow gas feed to the turbine wheel through a double-entry turbine housing, it is proposed to avoid [sic] the flow behaviour of the gas inside the turbine wheel and thereby a flow separation in the case of mixed-flow gas feed. For this purpose radially shorter secondary blades are arranged in the inlet side mixed-flow area of the turbine wheel between the main blades extending over the entire axial and radial length respectively.

Patent DE-4013626-C1 (DE)
Title: Semiconductor component - with weakly-doped N(-) and more highly-doped N partial zones
IPC: H01L21/322
Filed: 1990-04-27
Granted: 1991-05-29
Abstract: Semiconductor component (I) is produced having a semiconductor body (II) contg. an n-conducting zone which comprises a weakly-doped n(-)partial zone and a more highly-doped n-partial zone.  The (II) used contains thermally activatable donors.  The semi-conductor structure required for the function of (I) is produced in (II) without the n-partial zone; then the thermal donors are activated in the total (Ii) so the doping of the weakly-doped n(-)-partial zone is increased; and then the thermal donors in the area of the n-conducting zone, which is to form the n(-)-partial zone of (I), are de-activated whilst the remaining areas of the n-conducting zone remain as more highly doped n-partial zone. ADVANTAGE - The n-partial zone is not epitaxially deposited, nor are long-lasting deep diffusions required for its prodn.

Title: Integrated optical sensor for refractive index measurement esp. of liq. - has Mach-Zehnder interferometer formed from two arms of optical waveguide, and acousto=optical mode converter with continuously variable frequency
IPC: G01N21/45
Filed: 1991-11-21
Granted: 1992-12-24
Abstract: The integrated optical sensor determines the absolute index of refraction of a substance, esp. a liq., with a substrate body of lithium niobate. A single mode doubly refracting optical wave conductor is provided which extends along its surface between the two endfaces (7,10) of the substrate body (2). At a part of its length it is split into two arms of equal length. One arm on part of its length has a layer (19) of proton exchanged lithium niobate, insufficient for leading to a mode, and across a specified length makes optical contact with the substance, and these arms form a Mach Zehnder interferometer. The inlet face of the wave conductor is radiated with polarised light from a light source, and a light detector is acted upon with the measurement light radiated from the outlet endface of the wave conductor. The part of the optical wave conductor (6) split into the two arms (8,9) forming the Mach Zehnder interferometer is placed in the region (4) facing the outlet endface (10) of the surface of the substrate body (2). An acoustic-optical TM/TE mode converter (13) is integrated in the interferometer w.r.t. the transmission direction of the light, in a region (3) of the surface of the substrate body (2) connected to the inlet endface (7). The acoustic frequency of the TM/TE mode converter (13) is continuously alterable in a specified range. USE/ADVANTAGE - Integrated optical sensor allows determn. of absolute index of refraction of substances esp. of liquids with greater accuracy. Dispersion can be detected with help of this sensor.

Title: Signalling device for turbomachines (fluid-flow engines, fluid-kinetic machines)
Inventor: ZIELINSKI MICHAEL DR
IPC: G01H9/00
Filed: 1993-12-24
Granted: 1995-01-26
Abstract: A signalling device for turbomachines is specified which when the turbomachine is running delivers signals exactly at the instants at which the moving (rotating, rotor) blades pass through a defined circumferential position relative to the housing of the turbomachine; an optical probe is provided which emits in the direction of the rotor a focused illuminating beam through which each moving blade passes. The signals are obtained from the light reflected by the blades. The chief aims are that:   - the probe should be fixed radially on the housing with its head end and in a manner spaced from the end faces of the free blade ends, - the probe should have optical fibres for transmitting and receiving light, a cylindrical lens and a partially scattering cover plate, - the lens should focus a light bundle emerging divergently from an optical fibre in a plane such that the illuminating beam is generated with an elliptical cross-section, - the major axis of the ellipse should be aligned essentially parallel to the pressure-side or the suction-side edge of the relevant blade end faces, - a portion of the light reflected from the blade end faces should be lodged (coupled) via the cover plate into the optical fibres provided for the light to be received.
