Patent DE-3630124-A1 (DE)
Inventor: FAHL CHRISTOPH DIPL PHYS
IPC: G01B11/30
Filed: 1986-09-04
Abstract: To permit the testing of surfaces which have constricted access, such as grooves, bore holes and the like, a housing retains a laser light source, a collimator, a beam splitter and light detector. Light is reflected from the collimator, by a parallel offset dual parallelogram prism into an elongated hollow arm (8) which is pivotally mounted by a pivot axis (12) in the housing. The housing retains a positioning element (15) positioning the arm accurately with respect to the housing. A position transducer or sensing means senses repositioning of the housing to maintain the light spot from the laser, which is projected into the arm and outwardly thereof at right angles through an objective lens in focus. If the profile changes, the reflected light spot changes position on the light detector which controls the positioning system (15) to reposition the arm to maintain focus. The repositioning movement is detected by the position sensing or deflection transducer, which provides an output signal, representative of the change in profile on which the light spot is focussed.

Patent DE-3639139-A1 (DE)
Inventor: WEISS HARDY P DR SC TECHN
IPC: B05D1/06
Filed: 1986-11-15
Abstract: In a powder coating system wherein the powder is introduced via a feed conduit from the feed point to a mixing chamber, a pressure gradient oriented against the chamber is produced along the feed conduit by acceleration of a gas jet in the mixing chamber, and pressure recovery is obtained by retarding the powder-gas stream, in order to feed the powder-gas stream through a conveying line to a coating unit. For increasing the quantity of powder dispensed per unit time to the powder coating system, the pressure drop in the powder-gas stream along the conveying line is at least in part compensated for by raising the pressure at the feed point.

Title: Internal combustion engine, especially for motor vehicles
Inventor: GROSS RAINER
IPC: F02M26/36
Filed: 1987-04-16
Abstract: An internal combustion engine, especially for motor vehicles, has a throttle valve arranged in an air intake system, an idling air line connected parallel to the throttle valve, the through-flow cross-section of which line can be varied by an idling charge control device, controlled by engine parameters, a so-called vacuum regulator serving for actuation of the idling charge control device, and an exhaust gas recirculation line emerging from the exhaust system and opening into the idling air line, in which return line an exhaust gas recirculation valve is arranged, controlled as a function of the engine load and speed. Upstream of the idling charge control device, a reversing valve, actuated as a function of the engine load and speed, is arranged in the idling air line, which valve together with the idling charge control device serves to actuate the exhaust gas recirculation valve in the event of a certain throttle valve angle or a certain engine parameter being exceeded. Not only does the said device advantageously fulfil the function of an idling charge control, rather the actuator for the idling charge control (external air inlet) is converted into a vacuum governor for actuation of the (separate) exhaust gas recirculation valve once a certain (calibratable) throttle valve angle or engine parameter is exceeded.

Title: Arrangement for monitoring multi-digit subscriber numbers for telecommunications exchanges, especially telephone exchanges
Inventor: BRAUN HEINZ M DIPL ING
IPC: H04M3/38
Filed: 1987-07-29
Abstract: In the case of the arrangement for monitoring multi-digit subscriber numbers for telecommunications exchanges, especially telephone exchanges, a memory is provided which is constructed in the form of a matrix and can be addressed word by word, whose lines are addressed by a line address and whose columns are addressed by the respectively dialled digit of a subscriber number. The addressing of a first line to be selected for monitoring of the first dialled digit is carried out as a function of the authorisation class and/or group association of that connection from which a desired connection is set up. Each word assigned to a specific digit within a line contains either a command for completely enabling further digits, a command for breaking the connection or for further monitoring of a line address. A specific next line is addressed by this line address, the contents of which indicate the manner in which the next dialled digit is intended to be monitored. In this way, new memory lines are addressed and selected until a line is found in advance which contains no further line address in the word assigned to a dialled digit.

Title: Displacement machine for compressible media
Inventor: AHRENS JOERG
IPC: F04C18/02
Filed: 1988-01-15
Abstract: A displacement machine for compressible media is described, which has at least one displacement chamber arranged in a stationary housing and designed in the manner of a spirally running slot, strip-like or rib-like spiral-shaped housing walls of essentially constant radial thickness being formed between a number of displacement chambers. The displacement machine also has displacement bodies (3, 4) designed as spiral-shaped strips or ribs of essentially constant radial thickness which in each case are assigned to and engage in a displacement chamber and which are held essentially vertically on a disc-shaped rotor (1) which can be driven eccentrically in relation to the housing. In order to achieve a greater dimensional stability of the strip-like or rib-like displacement bodies (3, 4) or housing walls, the radial thickness thereof is to be increased in the region of their ends (9-12) lying in the circumferential direction. In this case, the radial strengthening is to be provided on one side towards the side facing away from the adjacent displacement bodies or housing walls and for example pass continuously from a starting value which is constant over the majority of the circumference to an end value which constitutes approximately 1.1 to 2 times, preferably 1.3 to 1.5 times, the starting value. <IMAGE>

Title: Temperature-dependent, electromagnetically controlled diaphragm water pump for motor vehicles
Inventor: MEINHARD WOLFGANG
IPC: F01P7/16
Filed: 1988-04-20
Abstract: When the ignition of the motor vehicle is switched on, the temperature-dependent, electromagnetically controlled diaphragm water pump is preheated via line (1) to the thermoswitch (2) via line (5) by means of heating rod (3) in the water-filled chamber (4) up to a temperature of approximately 80@C. At the same time, the engine has been started and is warming up. When the cylinder cooling water has reached the temperature of 80@C, the solenoid switch (27) is supplied with voltage which comes from the terminal 1 of the ignition coil via the thermoswitch (31). Voltage is applied to the solenoid valves (11) and (12) in the same period and also from terminal 1 via the line (8) which comes from the thermoswitch (31). By attracting the solenoid switch (27), the diaphragm (15) of the water pump is activated. The movement of the diaphragms takes place in a four cylinder engine four times per rotation of the engine since it is dependent on the cam of the distributor. <IMAGE>

Title: Method for the transmission of signals between a control-technology central processing unit and a drive unit for a power converter valve which can be switched on and off
Inventor: PEPPEL MICHAEL DR
IPC: G08C25/02
Filed: 1988-08-04
Abstract: For driving a GTO thyristor (5, 7), a separate valve drive unit (3, 6) is provided which is connected via optical waveguides (2, 9) with a control-technology central processing unit (1). The drive unit (3, 6) receives coded control commands (EAC) via a forward channel (2) and sends coded check-back signals (RMC) via a reverse channel (9). The coding is carried out by superimposing periodic marking pulses (MP) on the base logic level of the signals to be transmitted. The periodic marking pulses (MP) correspond to an equidistant succession of pulses, the duration (TB) of which is shorter than their temporal separation (TA). In the case of a low base logic level, the coded signals (EAC) are identical to the succession of marking pulses (MP), and in the case of a high base logic level the coded signals (EAC) are the logical inversion of the succession of marking pulses (MP). An at least 3-concept check-back is possible: "GTO thyristor blocking and drive unit O.K." "GTO thyristor conducting and drive unit O.K." and "all other conditions". <IMAGE>
