Abstract: A breastpump for expressing human breastmilk comprises a housing, a pump chamber with a driven pump membrane for producing a vacuum, and a breast shield with an interior for receiving a mother's breast. Expressed milk flows from the interior into the pump chamber through a milk channel, said pump chamber having an outlet opening through which expressed milk flows from the pump chamber into a milk collection container. The breastpump comprises a multipart hygiene module comprising a first part with a flow opening for connecting to the interior, a valve body with at least one valve and a second part with a rigid cup for forming the pump chamber. The valve body is arranged between the first and second part and the hygiene module as a whole is connectable to the housing of the breastpump in a sealing and detachable manner.

Abstract: It is provided an adjustment device for a vehicle seat, comprising an output element to which a drive torque can be transferred, and a brake assembly for locking the output element and absorbing, via at least two brake elements adjustably mounted in a brake housing of the brake assembly, forces applied to the output element on the output side, wherein locking, provided via the brake assembly, of the output element can be released in order to rotate the output element in a direction of rotation when a drive torque is applied on the drive side, and, in order to lock the output element, the brake elements are in a locking position in which, when forces are applied on the output side via the output element and are acting in a direction of rotation, at least one of the brake elements bears frictionally against a brake surface of the brake housing.

Abstract: A method is described for detecting brightness signals from a multiplicity of light-sensitive sensor elements, in particular CCD lines or arrays, in which the brightness signals are amplified in such a way that an A/D converter which digitizes the amplified brightness signals works in its permissible working range. For the brightness signal of a predetermined sensor element, the gain is reduced in steps, preferably in binary steps, from a maximum gain factor down to a working value at which the A/D converter works in the permissible working range. For each following sensor element, the working value of the respective preceding sensor element is used as the maximum gain factor. The number of changeover operations of the amplifier is considerably reduced and thus the detection time is shortened.

Abstract: A coated abrasive material comprising a textile backing--in the form of fabric, webbing, fleece and/or laminated material, base binder, abrasive particles and optionally size coat which is characterized in that the textile backing is extensible and that on the particle side an elastic intermediate layer is applied which lies between the textile backing and the usual base binder. This intermediate layer may contain caoutchouc latex and/or polyurethane and/or polymers, which contain butadiene and/or acrylic acid ester. The flexible and extensible coated abrasive may be used for profile grinding, sanding or polishing.
