Abstract: An electromagnetic brake with a housing body and a coil unit, wherein the coil unit has a positive connection to the housing body, wherein the coil unit is positively connected to the housing body by means of a snap-fit connection, wherein at least one snap hook of the coil unit is supported on a web of the housing body.

Abstract: An electromagnetic brake having a housing body, a friction disk, and at least one compression spring provided in the housing body, wherein the friction disk has a bayonet-type connection to the housing body, wherein the friction disk is secured against rotation relative to the housing body.

Abstract: An electromagnetic brake with a housing body and an armature disk, wherein the armature disk is guided axially via a groove-lug connection in the housing body, and wherein at least one guide groove and at least one associated guide lug are provided, wherein the respective guide groove is preferably arranged in the housing body.

Abstract: A textile insert consists of two layers (S.sub.1, S.sub.2) composed each of at least one partial layer (S.sub.1a, S.sup.1b, S.sub.2a, S.sub.2b). These layers are made of woven warp threads (1.sub.1a, 1.sup.1b, 1.sub.2a, 1.sub.2b) and woof threads (2.sub.1a, 2.sup.1b, 2.sub.2a, 2.sub.2b). Intermediate layers (Z.sub.1, Z.sub.2, Z.sub.3) made of standing threads (4.sub.1, 4.sub.2, 4.sub.3) that extend at least in the longitudinal direction X lie between the partial layers. The whole system is held together by straight or curved connecting threads (3.sub.1, 3.sub.2). A stable textile insert is thus obtained that allows fibrous composite materials to be produced without distortion by a pultrusion process. Sections made of such fibrous composite materials are in addition highly resistant in all three directions.

Abstract: An ironing machine with a computer-assisted control device for the advancing pressure and the pressing time between an upper and a lower shaping board (10, 16) which are movable relative to one another both vertically and horizontally, the ironing machine has a differential-pressure regulating device (1 to 6, 11) which, during the computer-controlled application of pressure to the article to be ironed, takes into account the dead weight of the movable shaping board, as a rule the upper shaping board (10). A substantially higher ironing quality, especially where sensitive textiles are concerned, can be achieved by the invention, because the ironing pressure can be preselected reproducibly within very fine steps.

Abstract: An ironing machine provided with a pair of press plates are juxtaposed with respective elastic webs on tensioning frames which can stretch the webs with the article to be pressed between them so as to tension the article outwardly from the center on both sides, the tension being maintained during pressing.
