Title: Process for detecting the water quantity which has flowed into the tub of a drum-type washing machine
Inventor: GRAF RICHARD DIPL ING
IPC: D06F39/08
Filed: 1981-10-21
Abstract: A process for the exact detection of the water quantity which has flowed into the laundry-filled tub (1) of a drum-type washing machine, by means of a high-resolution level sensor (9) responding to the pressure in a hose line (8) connected to the tub, is sought, so that metering devices for powdery or liquid washing agents in drum-type washing machines can supply a dose of washing agent exactly coordinated with the water quantity which has flowed in. In such a process, when an upper level value (NO) is reached the water inflow (5) is shut off and, during the drop to a lower level value (NU), the water inflow is opened again, and a specific first period of time after the upper level value (NO) is reached for the first time the drum is stopped, and a specific second period of time after the drum is stopped the measurement of the true level (N2) of the water quantity which has flowed in is carried out. <IMAGE>

Title: Valve, especially for corrosive media
Inventor: STAEHLE KURT ING GRAD
IPC: F16K31/06
Filed: 1982-04-22
Abstract: A valve is described which is especially suitable for corrosive media and consists of a controllable valve body with a sealing plate which is pressed in a spring-loaded manner via a compression element which engages centrally on it against a flat sealing seat with an annular sealing surface. In this case, the sealing plate is constructed as a small sealing plate which is bent elastically by the spring force, and a stop, which limits the movement of the compression element and absorbs the spring force when the valve body is lifted off, on the valve body is allocated to said compression element. The advantage of the novel design is that the machining accuracy can remain considerably less than known types. The sensitivity to contamination of the novel valves is also less.

Title: Electric motor with automatically operating brake
Inventor: HAVERKAMP HANS
IPC: H02K7/102
Filed: 1982-05-11
Abstract: An electric motor is equipped with an automatically operating brake which has a brake element which can be displaced on the rotor shaft against an energy store, such as especially a helical spring, is constructed like a pot and is raised by the magnetic field of the rotor. A disc, which moves independently of an armature plate, is guided axially inside the brake element by said brake element, which is closed towards the rotor by the armature plate, inclined tiers being arranged symmetrically with respect to the axis on said disc, which tiers have the shape of annular segments, run around the rotor shaft, rise in both rotation directions of the rotor shaft, face the rotor and are pressed against a starting pin, which is inserted into the rotor shaft, by means of a pretensioned spring which is located between the base of the brake element and the disc. In order to increase the braking force of the automatic brake, whose braking effect is limited by the relatively small diameter of the brake element, a multi-plate brake is connected upstream of the brake element, is operated by said brake element and consists of brake rotors which move axially on the rotor shaft and rotate with said rotor shaft, and of brake discs which are opposite said brake rotors, are likewise guided so that they move axially with respect to the rotor shaft, but are impeded from making rotating movements.

Title: Endlessly circulating conveying belt with drivers
Inventor: HARTMANN KARL
IPC: B65G15/42
Filed: 1982-12-23
Abstract: The present invention relates to endlessly circulating conveying belts with drivers between corrugated edges, in particular those which are used for conveying heavy, adhesive materials. In the case of said conveyor belts, the bulk materials tend to become attached, in particular on the drivers, which is intended to be prevented according to the invention in that at least the surfaces O, of the drivers M, pointing in the conveying direction F are covered by means of a flexible apron S. This apron S may be connected to the driver M, in a movement-compensating manner P, at the borders R and, in addition, be charged with materials of high relative density. This results in a high self-cleaning effect. <IMAGE>
