Abstract: An inexpensive lamination for use in transformers and/or other static or dynamic electric machines has a metallic layer one side of which is provided with a coat of hardenable adhesive and the other side of which is provided with a coat of insulating material. At least the adhesive coat can contain particles of sand, glass, a metallic oxide or a synthetic plastic material; such particles act as distancing elements between the respective side of the metallic layer and an adjacent metallic layer. The two coats are applied simultaneously between an unwinding station for a web or strip of coherent metallic layers and a winding station for the freshly coated web or strip of coherent metallic layers.

Abstract: Laminated iron core for transformers, choke coils and the like includes a plurality of core parts overlying one another at respective mutually opposing abutment locations, the respective mutually opposing abutment locations defining a space of varying width between one another, the core parts being disposed so as to form a relatively short closed inner path and increasingly longer closed outer paths for magnetic force lines, the space having a region of relatively greater width across which the relatively short closed inner path extends.

Abstract: A stepped iron core formed of sheetmetal laminations for a static or dynamic electric machine, such as a transformer, having yokes and legs and intermediate parts of at least one thereof including stacks of the sheetmetal laminations mutually held together forming individual steps of the yokes and the legs, the yoke stacks and the leg stacks being joinable with one another at respective abutment joint locations formed thereon, and means located at the respective abutment joint locations for achieving a varying magnetic reluctance therebetween so that a longer path of lines of force passes through the respective abutment joint locations in the region thereof of lower magnetic reluctance.

Abstract: In an automatic towel dispenser having a housing containing a washing and a drying chamber for an endless towel passable therethrough and having a cleaned section available for use extending outside the housing between a delivery slot and an inlet slot, respectively, formed in the housing, the endless towel being movable from the inlet slot to the washing chamber and from the drying chamber to the delivery slot, the housing also containing a first supply chamber for variably stacking a plurality of soiled towel sections of the endless towel therein, the first supply chamber being located between the inlet slot and the washing chamber, as viewed in travel direction of the towel, and the housing further containing a second supply chamber for variably stacking a plurality of cleaned towel sections of the endless towel therein, the second supply chamber being located between the drying chamber and the delivery slot, as viewed in travel direction of the towel, the soiled towel sections, after emptying of a given q

Abstract: An automatic towel dispenser whose housing contains a washing and a drying chamber for an endless towel which can pass therethrough and has a cleaned section available for use and extending from the housing between a delivery slot and an inlet slot of the housing. The towel is movable from the inlet slot to the washing chamber and from the drying chamber to the delivery slot, and the housing also contains a first supply chamber for variably stacking a plurality of soiled towel sections and a second supply chamber for variably stacking a plurality of cleaned towel sections. The washing chamber has at least one wash and at least one rinsing tub through which the towel can pass in the form of loops. The dispenser is further provided with a water feed valve and a water discharge valve connected to the washing chamber. The water feed valve is actuatable at the start of a washing cycle and the water discharge valve is actuatable on completion of the washing cycle.

Abstract: Automatic towel dispenser has a box-shaped housing provided with a washing chamber and a drying chamber for an endless towel to be guided therethrough, the towel having a cleaned partial length thereof available for respective use and being guidable over a locking device for limiting the clean partial length of the towel to be withdrawn and guided outside the housing between an outlet opening and an inlet opening formed in the housing, a first storage chamber located in the housing between the inlet opening and the washing chamber for variably piling up therein a plurality of used partial lengths of the towel, and a second storage chamber located in the housing between the drying chamber and the outlet opening for variably piling therein a plurality of cleaned partial lengths of the towel, and means being activatable, upon the emptying to a given extent of the cleaned partial lengths of the towel in the second storage chamber, for passing used partial lengths of the towel through the washing and drying chambe
