Abstract: A foldback door system for at least partially closing an opening having at least one plane, the system including at least two mutually pivoted panels movable between a closed condition relative to a frame having at least one jamb relative to which the at least two mutually pivoted panels are hung, the at least two panels including a lateral panel located closer to the jamb and an inner panel hinged relative to the lateral panel and the frame, the lateral panel being of a first dimension and the inner panel being of a second dimension different to the first dimension, the closed condition in which the at least two panels are in substantial alignment to at least partially close the opening and a fully open, foldback condition in which the at least two panels are substantially parallel with one another and lie at an angle of greater than 90° with respect to the at least one plane of the opening in which the at least two panels lie in the closed condition.

Abstract: A diagnosis method for identification or localization of errors in tempering devices for tempering of systems includes providing tempering devices each comprising one or more first sensors and one or more components for securing an operation of the systems with the tempering device, and one or more second sensors for measuring a state of the tempering device or ambient conditions around the tempering device, determining the tempering device to be checked with a diagnosis procedure, decoupling the tempering device from the system, connecting the tempering device to a defined consumer, and conducting the diagnosis procedure for the tempering device by using a diagnosis program, where the diagnosis program checks the components and the first and second sensors of the tempering device in a pre-determined sequence stored in the diagnosis program until the error in the tempering device is identified or localized.

Abstract: A pull across screen assembly has a flexible screen member (e.g. flymesh) wound about a vertical rod positioned at one side of the opening. A line member arrangement is attached to the front of the screen member and part of the line member winds about a tapered drum which is positioned on top of rod and which rotates with rotation of the rod. The arrangement allows the screen member to be tensioned and also to be balanced as it is pulled across the opening.

Abstract: A carrier hinge assembly is used to suspend adjacent hinged panels from a track. The assembly has a carriage which travels along the track, and a hinge dependent from the carriage. The hinge is formed by a hinge pin having an upper portion threaded into a boss on the carriage, and hinge leaves which are pivotable about the hinge pin. The hinge leaves are fixed, in use, to opposing edge faces of the panels. The height of the panels may be adjusted by rotation of the hinge pin. A locking mechanism includes a retractable lock tongue located in an axial slot in a stop at the bottom of the hinge pin. The lock tongue is biased by spring to engage an axial slot in hinge leaf, to key the hinge pin to the hinge leaf and prevent relative rotation.

Abstract: A carrier hinge assembly is used to suspend adjacent hinged panels from a track. The assembly has a carriage (30) which travels along the track, and a hinge (34) dependent from the carriage (30). The hinge is formed by a hinge pin (35) having an upper portion (39) threaded into a boss (32) on the carriage (30), and hinge leaves (36, 37) which are pivotable about the hinge pin (35). The hinge leaves (36, 37) are fixed, in use, to opposing edge faces of the panels. The height of the panels may be adjusted by rotation of the hinge pin (35). A locking mechanism includes a retractable lock tongue (40) located in an axial slot (42) in a stop (38) at the bottom of the hinge pin (35). The lock tongue (40) is biased by spring (50) to engage an axial slot (58) in hinge leaf (37), to key the hinge pin (35) to the hinge leaf (37) and prevent relative rotation.

Abstract: A combination carrier and hinge assembly (10) for track-mounted adjacent panels comprises a butt hinge (11) having hinge leaves (14, 15) edge-fixed to adjacent panels (12, 12a). The hinge 11 also has a hinge pin (17) which extends above the hinge and is threaded into a carriage (13) which travels along a track (20). The fixing of the hinge leaves (14, 15) to the panels (12, 12a) is concealed when the panels are closed. A guide hinge (25) is provided at the bottom of the panels (12, 12a). The guide hinge (25) is a non-mortise butt hinge having leaves (26, 27) edge-fixed to the panels (12, 12a). The guide hinge (25) also has a hinge pin extending below the panels, and locating in a guide channel (23).
