The guide strips guide the sheet material between and around the rollers. Exemplary rollers have a plurality of grooves spaced across the width of the path, and the guide strips are received in respective grooves. The guide strips may be connected by a crossbar to form a guide member.

Abstract: The bottom tier (24) of a conveyor belt (22) arranged in a spiral stack (26) is supported by and driven by inner and outer drive chains (28) and (30). The inner and outer drive chains are supported on and ride along support rails (32) and (34). The inner and outer drive chains are driven by a drive system (35) composed of inner and outer drive systems (36) and (38), each including a drive motor with a drive gear engaged with the inner and outer drive chains. Each of the motors is controlled by a separate variable frequency drive unit (114) and (116) which in turn are controlled by a control system (44). The control system (44) also controls the operation of a lubrication system (40) that supplies lubricant to the drive chains.

Abstract: The invention at hand relates to a tracheal applicator for enabling administering high flow therapy to tracheotomy patients, as is known from transnasal insufflation by means of TNI devices and has proven successful. This is attained by an optimized physical simulation of the conditions as available when performing transnasal high flow therapy at the nostril with an inserted prong. The flow of inspiration and expiration flowing through the tracheal applicator is conducted nearly free of turbulences and vortexes owing to further constructive measures while simultaneously preserving an open ventilation system.

Abstract: A screw connector for medical hose systems is configured for catch engagement in a half-open sterilization position. The connector includes a first connecting element having a first lumen and an outside thread, and a second connecting element having a second lumen, and an elastically deformable union nut having an inside thread. The inside thread and the outside thread are configured to be screwed together, with the outside thread having a first formation and the inside thread a second formation, with deformation of the nut via the first formation in a predetermined first angle-of-rotation range without engaging the second formation. The inside thread and the outside thread, and the first formation and the second formation, are configured for catch engagement of the first formation in the second formation when the inside thread and the outside thread are screwed together in a predetermined second angle-of-rotation range to provide the half-open sterilization position.
