Abstract: Personal protective equipment includes an information display area, wherein the information display area comprises an information carrier for displaying information of a first application and a second application of the personal protective equipment, wherein the information display area in a first of at least two states exclusively displays information relating to the first application and in a second state exclusively displays information relating to the second application, and wherein the display of the information display area is switchable back and forth between the at least two states a plurality of times. Furthermore, the invention relates to a method for changing a state of an information display area of a personal protective equipment.

Abstract: A buckle arrangement has a first buckle and a second buckle connectable to the first buckle. The first buckle has a first locking device and a first locking hook, and the second buckle has a second locking device and a second locking hook. The first locking device and the second locking device are formed such that, when the first buckle is connected to the second buckle, the first locking device locks the second locking hook and the second locking device locks the first locking hook.

Abstract: The invention relates to a buckle arrangement, having a first buckle (1) and a second buckle (2) connectable to the first buckle (1), wherein the first buckle (1) has a first locking device (5) and a first locking hook (6), and the second buckle (2) has a second locking device (7) and a second locking hook (8), the first locking device (5) and the second locking device (7) are formed such that, when the first buckle (1) is connected to the second buckle (2), the first locking device (5) locks the second locking hook (8) and the second locking device (7) locks the first locking hook (6), such that the first buckle (1) is connected to the second buckle (2), and the first locking device (5) and/or the second locking hook (8) are formed identically and/or symmetrically, particularly point-symmetrically, to the second locking device (7) and/or the first locking hook (6), at least in respect of the locking.

Abstract: A catching ribbon for catching and holding a thread on a thread support, such as a thread wind-up bobbin rotating at high speed, is provided at its circumference with catching elements. These catching elements comprise thread engaging portions, such as hooks. The space between two thread engaging portions of two immediately adjacent catching elements are positioned to allow a single thread passage therebetween but precluding thread retro-movement. The catching elements comprise miniature pins provided with heads configured to form the thread engaging portions, such as semi-circular heads or anchor-like heads similar to kedge anchors. Catching elements with a single thread engaging portion, such as a single hook, also may be provided. Successive rows of the single-hook catching elements or successive rows of the double-hook catching elements may be arranged in staggered relationship.
