Abstract: The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.

Abstract: The present invention relates to a high-speed controlling device (8), suitable for displacing a switching element (6) between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature (19), with a driven coupling to the switching element (6), is arranged. According to the invention, said armature (19) contacts the first electromagnet in the first position of the switching element (6) and contacts the other electromagnet in the second position of the switching element (6). In order to obtain particularly short switching times for the switching element (6), the armature (19) can be firmly secured to a shaft (21), which is rotatably mounted about its longitudinal axis and to which said switching element (6) is also fixed in an axially offset manner in relation to the armature (19).

Abstract: A wound dressing comprises a chemically modified polymer which has a free radical activity in the DPPH Test in the range 15-80 percent. It may comprise a chemically modified polymer which carries at least one chemical group which is a persistent free radical or a precursor therefor. It may comprise a chemically modified polymer which carries at least one chemical group capable of reacting with molecular oxygen in a wound environment to form hydrogen peroxide. It may comprise a chemically modified polymer capable of stimulating the activity of macrophages or the proliferation of fibroblasts or both in a wound environment.

Abstract: A vending machine for fast food articles such as warm burgers comprises a freezing store, a microwave oven and handling and control device for successively transferring a paper wrapped article from the store to the oven and, thereafter, from the oven to a delivery position. The oven has a bottom hinged door, the rear side of which is provided with an article carrier plate having a shape suitable for receiving the articles when the lid is partly open and for bringing the articles into the oven in response to the door being closed. Moreover, the carrier plate serves to guide the heated articles out of the oven into a dispensing receptacle in response to the door being opened to a fully open, downwardly inclined position.
