Title: Overload protection arrangement in a device for applying ultrasound to liquids
Inventor: KOLLER WILHELM ING GRAD
IPC: A61H23/02
Filed: 1981-05-09
Abstract: The invention contains an overload protection arrangement in a device for applying ultrasound to liquids, which comprises a sound generator (source), to which an oscillating circuit is applied and which is to be protected against running dry, in a container which is to be filled with the liquid. There is a sensor which responds when the liquid level in the container drops below a prescribed value. It is provided to use the arrangement in inhalation apparatuses, in particular. In contrast to the state of the art, in which a minimum liquid level is maintained by float controllers or by turn-off electrodes bridged by the liquid, in accordance with the invention turning off is performed when there is a rise in the circuit quality of a resonant circuit, containing the sound generator, of the oscillating circuit. The mode of operation of this arrangement is independent of the possible corrosion of components, and thus very reliable. In addition, easy cleaning of the container to be filled with the liquid is enabled, since only the sound generator is arranged in the latter. <IMAGE>

Title: Winding apparatus for web-like material for the production of winding rolls without a winding core
Inventor: SANWALD MANFRED
IPC: B65H18/00
Filed: 1981-07-16
Abstract: The winding apparatus for web-like material possesses, for the production of winding rolls without a winding core, a winding cage (2) consisting of driven winding members (3) which are arranged externally on a cylindrical enveloping surface which defines the winding axis (5) and winding diameter and in which they bear on the roll circumference of the winding roll and drive the winding roll. Provided axially on each of the two sides, outside the winding width required for the winding roll, but still in the winding cage (2), is in each case a winding mandrel (12) which is coaxial with the winding axis (5) and which can be driven about its axis in the winding direction independently of the winding members (3). Furthermore, the mandrels (12) are provided on the outside with thread flights (12.2) which, with their thread direction, result in an axial displacement of the winding mandrels (12) towards the middle of the winding cage (2), when the winding mandrels bearing on the winding members (3) have on the contact surfaces a higher circumferential speed than the winding members (3). Finally, the mandrels (12) can each be supported axially, outside the winding cage (2), on a traveller (16) which can follow displacements of the winding axis (5) in a plane perpendicular to the winding axis. During the winding operation, the mandrels (12) screw themselves into the innermost turn of the winding roll and thereby also drive from inside the winding roll which consequently cannot come loose by itself. <IMAGE>

Title: Paint-spray cabin with integrated device for heat-recovery from the exhaust-air streams
Inventor: HERBOLD GOETZ PETER
IPC: B05B14/46
Filed: 1981-07-31
Abstract: The invention relates to the technical field of systems for coating surfaces (for example with paints). Specifically these are systems in which the coating material is sprayed and the cabin exhaust-air is scrubbed with water. In the known paint-spray cabins, the heat-recovery from the exhaust-air stream (for preheating the colder fresh air) can be carried out by the installation of heat-exchanger systems downstream of the device for exhaust-air scrubbing. In this case the soiling of the heat-exchanger surfaces by the paint droplets not separated out is unavoidable. The device for the heat-recovery is arranged directly downstream of the device for mixing the exhaust air with the water (scrubber system) in such a manner that the heat-exchanger surfaces are also acted on by the water then contained in the exhaust air. The separating-out device for separating the water droplets from the exhaust air is arranged downstream of the heat-recovery device. The accompanying drawing (Fig. 1) shows the exhaust-air stream: the individual items are:     1) heat-recovery system   2) additional scrubbing device for heat-exchanger surfaces   3) painting zone   4) scrubber system   5) water basin 6) zone in which the paint droplets and water droplets are present in the exhaust air   8) exhaust-air pipeline   9) exhaust-air fan 10) overflow tank for producing the rear wall down which water constantly flows.   The fresh-air stream also flows through the heat-exchanger and is completely separate from the exhaust-air stream. <IMAGE>

Title: Hose or pipe coupling
Inventor: MOMBERG WOLFGANG DIPL ING
IPC: F16L37/32
Filed: 1981-09-12
Abstract: The invention relates to a hose or pipe coupling which is of large nominal width and is intended for large valve forces to be overcome, having a self-shutting valve body (10) and having an annular piston (9) which is spring-loaded in the closing direction of the valve and, acted upon by a pressure medium, raises said valve body from its seat, and having a shut-off ball locking mechanism (16/17/23) with a locking sleeve (19) on one coupling half (1), the annular piston (9), independently of the throughflow medium, being acted upon, from outside, by a pressure medium via a line which can be attached by means of a quick-acting coupling (31/32), and a locking member which fixes the locking sleeve (19) in the coupling position being provided. In order to simplify the construction and improve the operating reliability, the invention proposes that the locking member be formed from one coupling half (32) of the pressure-medium connection quick-acting coupling which, being transversely directed, is arranged in the opening displacement path of the locking sleeve (19) which is locked in its opening position against advancement into its basic position, and that the catch be disengageable from a control surface (38) of the other coupling half (4). Separating the coupling half (1) from the associated coupling half (2) is thus possible only after removing the coupling half (32) of the pressure-medium connection coupling. <IMAGE>

Filed: 1981-09-17
Abstract: Control unit for an electric vehicle, preferably for disabled people. The control unit contains a first and a second pair of inputs and a first and a second control output. At one of the inputs it receives a certain number of digital input signals as a function of the selected actuation of a transmission unit. It supplies analog output signals to its control outputs, which output signals form control signals which influence the drive and a device for changing the direction of travel. The said control signals can be varied as a function of the state of the inputs of the control unit. The value of one output signal constitutes a selected speed in the forward direction or reverse direction whilst the second output signal constitutes the selected direction of travel to the left or to the right.

Title: Circuit arrangement for inductive transmitters
Inventor: KNOEDLER JUERGEN DIPL ING
IPC: G01D3/036
Filed: 1982-03-25
Abstract: An evaluating circuit for inductive transmitters, particularly short-circuit ring transmitters, is proposed which has high accuracy. For this purpose, the temperature is sensed by means of a temperature sensor and used for compensating for temperature errors. Furthermore, a distance-dependent signal is formed. The distance-dependent signal is also used for correcting the characteristic of the inductive transmitter. A suitable mixing results in that temperature errors which are additionally dependent on distance can also be compensated for. <IMAGE>
