Patent DE-3902765-A1 (DE)
Title: Device for transmitting plane waves from a vibration transmitter with periodic excitation (generation of plane waves) in a fluid, cylindrical guidance system onto the object surface
Inventor: BOEHRINGER VOLKER ULRICH
IPC: B08B3/12
Filed: 1989-01-31
Abstract: The device for transmitting plane waves in a fluid represents the coupling system between the vibration transmitter (power source) and the object surface (power sink) to be treated. This is normally performed in liquid-filled spaces having power distributions which are unequal because of standing waves (natural resonance (self-resonant frequency)), i.e. dead regions on the nodal lines and gas-filled cavity shadows as a fixed position function (eigenvalues of the solution of the wave equation in tightly limited spaces). It is possible using the device developed (coupling system) to clean relatively large surfaces of high coating quality by means of continuous power (fixed cavitation) and in so doing to treat the entire surface. The power distribution (natural resonances) which is not spatially fixed permits adaptation to the power output even in the case of change in the coating during the working operation.

Title: Cooling drum for stuff-crimping devices
Inventor: RUNKEL WALTER DR ING
IPC: D02G1/12
Filed: 1989-04-11
Abstract: It is known, in the case of stuff-crimping, to cool down the hot thread plug emerging from the stuffer box, before it is disentangled, first of all with the aid of a cooling drum whose surface exhibits wedge-shaped guide grooves with a perforated groove base for receiving the thread plugs. The drum interior is connected to a suction-extraction means via a lateral suction-extraction cross-section. It has been shown that, due to the suction extraction on one side, the cooling action decreases as the distance from the suction-extraction cross-section increases. The novel cooling drum is intended to change this. Provided in the interior of the cooling drum are air guides which, with the greatest possible radius of curvature in each case, are guided from the guide grooves to the suction-extraction cross-section. They have the same effective length and the same cross-sectional progression. The configuration of the air guides can take place by arranging correspondingly shaped rotationally symmetrical inserts in the drum. The novel cooling drum results in identical flow conditions, in the case of all guide grooves, and thus to uniform cooling of the thread plugs.

Patent DE-3919183-A1 (DE)
Inventor: MAEDER ROLF
IPC: G06F1/30
Filed: 1989-06-12
Abstract: An energy store (C) for temporarily supplying loads (MC1 to MCn) during switching over of the power supply devices (GR1, GR2) in the event of a disturbance and for briefly supplying the monitoring circuit is provided. When energy is taken from the energy store (C) as a consequence of a voltage interruption, a voltage drop occurs on a component (D2 to D5) which is sensitive to the current direction, to switch through an electronic switch (OPK0). Within a few microseconds, this switch triggers a disturbance report (55) and hence informs computers (MC1 to MCn) which are connected to the supply voltage of the disturbance which has occurred. A changeover relay (UR), located in the supply circuit of the electronic switch, permits the switching over of the power supply devices and is self-latched to maintain the disturbance report. The circuit is provided with test contacts (PT/1) for functional testing and with resetting contacts (RT/1) for returning to the basic position of the circuit. Said circuit is used for detecting dynamic voltage reductions in the power supply of computer systems. <IMAGE>
