摘要:
An apparatus for detection of the accuracy of format of a web of corrugated cardboard moved in a conveying direction comprises a light source which emits a light band to the surface of the web of corrugated cardboard in a direction crosswise of the conveying direction and at an angle to the web of corrugated cardboard. A measuring camera detects the different light intensities of the light reflected by the plane portions and the profiled patterns of the web of corrugated cardboard. This electronic image in the camera is evaluated by an evaluation device for determining the distance of the profiled patterns from each other.

摘要:
A recording device is for recording the switch state of an electromagnetic switch device. In at least one embodiment, the recording device includes a housing, in which a plunger is movably mounted. The plunger may be moved between two mechanical end positions, wherein the end positions of the plunger correspond to the switch states of the electromagnetic switch device. A sensor device is arranged in the housing by which it may be recorded in which of the end positions the plunger is and from which a corresponding electrical signal may be emitted. The sensor device is designed to be able to record the position of the plunger without contacting the plunger.

摘要:
A molding composition which is essentially composed of a mixture of at least two polymers based on vinyl chloride and at least one water-soluble surfactant is described. One of the polymers is a sinterable vinyl chloride/alkyl acrylate copolymer which can contain, in addition, polymerized units of vinyl acetate and ethylene. At least one further polymer is a vinyl chloride polymer which can contain up to 5% by weight of polymerized units of vinyl acetate and ethylene. The molding composition is suitable for the production of sintered, porous, flexible moldings, in particular separator compartments for electric cells.
