Title: Laser diode/laser Doppler anemometer
Inventor: DOPHEIDE DIETRICH DR
IPC: G01P5/00
Filed: 1984-02-21
Abstract: The invention relates to the field of flow measurement engineering by means of laser Doppler anemometry. The application concerns a laser Doppler anemometer of miniature design based on laser diodes of tunable wavelength with wavelength stabilisation. Different optimised possibilities are described for using laser diode anemometers, and arrangements are explained for single- and multi-component anemometers, in particular for 3 orthogonal velocity components. A temperature-controlling element 12 of the laser diode 1 enables wavelength tuning and, in conjunction with a current-regulating device 13, stabilisation of wavelength and output. A current modulation device 14 and 14a can be used to produce frequency mixing of the Doppler frequency and the modulation frequency, so that it is possible to shift the Doppler frequency. The invention enables the construction of miniature laser Doppler anemometers of the very smallest dimensions and lightest design for all purposes of flow measurement engineering. <IMAGE>

Patent DE-3429990-A1 (DE)
Title: Floating device for rescuing and saving persons at risk of drowning
Inventor: SCHAEFER LUTZ
IPC: B63B7/08
Filed: 1984-08-16
Abstract: Floating device for rescuing and saving persons at risk of drowning by persons instructed in lifesaving. For various reasons, lifeboats cannot be used at many beaches, coasts and inland stretches of water. The device described here enables a rescuer to approach a person at risk of drowning even at rough shoreland and in the face of higher breakers and enables the person to be transported to the shore, in the course of which his head is held safely above water and the overstretching of his cervical vertebral column can lead to resuscitation. This not only increases the chances of success of the measure for the person to be rescued but also serves to protect the rescuer. The device is unsinkable and maintains its stable position even in a heavy swell. Manipulation is simplicity itself; risk to the user from the type of propulsion is impossible. The speed can be increased if the rescuer lying on the device at the same time uses flippers. Finally, it may be mentioned that, in contrast to other floating aids, it is completely irrelevant for the speed of the rescue measure and for the expenditure of force required whether and to what extent the rescuer and the person to be rescued wear clothing.

Title: Tandem head drive for belt conveyors
Inventor: POHLE HELMUT
IPC: B65G23/14
Filed: 1984-10-30
Abstract: The belt conveyors used in underground mining and tunnel construction are equipped with structurally simple and versatile head drives, the latter having a longitudinally displaceable tail pulley between the two driving pulleys mounted in the base frame. The said tail pulley is assigned to a tensioning trolley, which is movable in its turn in an intermediate frame which has a variable length and structure and is supported between the two outside frames which are arranged at the ends and support the driving pulleys. The tensioning assembly which exerts a load on the tail pulley is a hydraulic cylinder with a hydro-pneumatic accumulator, so that the necessary pretensioning can be continuously applied without special drives. Furthermore, a rubber belt reserve is kept in readiness between the two driving pulleys and facilitates the repairs which become necessary by dispensing with the need to patch intermediate pieces. Furthermore, application of the necessary prestressing is significantly facilitated once such a connecting seam has been produced. <IMAGE>

Title: Method and arrangement for the program control of a washing machine
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F34/18
Filed: 1984-12-19
Abstract: Method for the program control of a washing machine with a water inflow of regulated water level, in which the water quantity which flowed into the tub at the start of the washing program is detected by a measuring device, and in which different washing-process criteria, such as the water level, number of washing or rinsing cycles, washing-agent metering and the like, can be fixed in dependence on this inflow quantity. The measured values detected by the measuring device and dependent on the water level are fed to an evaluator and are processed by this in such a way that the measured level fluctuations per filling cycle (filling step) in the tub and the number of counter-recorded tub water refillings per washing stage are communicated to a computer. The communicated measured and signalled values are a measure of the absorbency of the type of laundry entered in the program control. The individual washing-program parameters for the particular type of laundry introduced are then determined from these in the computer.
