Abstract: A divided flexible covering (1,2)serves to expose any desired region of a surface or opening while masking the other regions. Two gripping slats (3,10) are located respectively at the beginning of a length of fabric (1 or 2) or at the beginning and end of at least one or two strips (4 or 8), each of which is guided endlessly over four rollers (5,9) or sliding blocks (47). Each length of fabric (1 or 2) is provided with an end piece (7 or 12). The length of the lengths of fabric (1 or 2) is approximately half that of the strips (4 or 8). The end pieces (7, 12) are mutually offset and are provided with a slot (14a) or are attached to a rod (43) provided for the other length of fabric, so that when a covering part (1), for example, is pulled down over the center of the cupboard, the covering part (2) is pulled simultaneously because one end piece (7) entrains another end piece (12) upward in the direction of traction. The operations are indentical in the opposite directions.

Abstract: A door structure including a retractable cover which has a rolling up section which is rotated so as to roll up and unroll a portion of the cover. Generally an upper edge of the cover portion is fixedly mounted to a roof portion of a door structure and the lower edge is free. The rolling up section is non-rotatably connected to the cover portion along a center line. Rotation of the rolling up section in one direction rolls up the cover portion and rotation in the other direction unrolls the cover portion. The rolling up section moves up and down respectively with the rolling up and unrolling of the cover portion. The rolling up section can be caused to rotate by toothed wheels at one end engaging with spaced rollers mounted on a framework associated with the cover. The cover portion extends, in a particular arrangement, between two end portions, although only one end portion may be provided.

Abstract: A vehicle window screen assembly selectively and alternately operable to cover or uncover a vehicle window. The assembly includes a first flexible screen for blocking at least a portion of light impinging thereon, and a spring-loaded, generally cylindrical roller about which the screen is wrapped with a free end exposed, the roller being mountable at its ends on a side of the window to be covered so that when the free end of the screen is pulled toward the opposite side of the window, the roller rotates to unwind the screen and when the free end is released, the roller retracts and rolls up the screen. A screen positioning device is attached to the free end of the screen and is controllable to selectively pull the screen toward the opposite side of the window to substantially cover it, or to release the screen to allow it to be retracted and rolled up on the roller.

Abstract: A window cornice assembly including two spaced cornice terminals, two shade retaining brackets, and a tapestry cover assembly including a replaceable spring-loaded cartridge and a tapestry cover. The tapestry cover is an elongated sheet of material having two ends. The first end is attached to the spring-loaded cartridge and can be rolled up around the cartridge. The second, or free, end includes a fastening member. One of the cornice terminals includes brackets for rotatably receiving the spring-loaded cartridge. The other cornice terminal includes a receiving member to which the fastening member can be attached. The cartridge is inserted in the brackets and the tapestry cover pulled around the terminals until the fastening member is attached to the receiving member. The cartridge is easily removable from the brackets so that different cartridges containing different designs can be substituted as desired. The shade retaining brackets are attached to each terminal.

Abstract: Two rolling bands, meaning windable and unwindable bands, are affixed to a carriage or slide which is reciprocatingly movable along a guideway. The rolling bands are each arranged to be rolled-off from a respective drum journaled at each end of the guideway. A respective wheel is rigidly coupled to each one of the drums. Two belts interconnected by a tension spring are each arranged to be wound-up upon a respective one of the wheels in opposite direction to the winding direction of the rolling band on the related drum. Without itself being subjected to substantial loading and elongation differences, the tension spring continuously holds both of the rolling bands under tension.

Abstract: An insulating device reduces heat transfer through a barrier--such as a wall, window, door, floor, or ceiling of a building--and into an area adjacent to the device. The insulating device includes at least one flexible sheet supported from an area above the section of the barrier to be insulated and is attached at its free end to the barrier above that section. Accordingly, the flexible sheet is doubled back upon itself and forms an insulating air space. A second flexible sheet can be attached to the support and disposed around the exterior of the first flexible sheet and attached to the barrier above the section to be insulated. Where two flexible sheets are doubled back upon themselves in such a manner, three insulating air spaces are provided. Accordingly, the insulating device impedes conductive heat transfer across the device. At least one flexible sheet includes a material having a low emittance to reduce radiant heat transfer across the device.

Abstract: A fiber bale opener includes a truck arranged for back-and-forth displacement along a travelling path, an opening mechanism carried by the truck and arranged for removing fiber from the top of fiber bales positioned along the travelling path and a suction apparatus for carrying away, by an air stream, fiber removed from the bales by the opening mechanism. The suction apparatus includes a suction duct extending in the direction of the travelling path and a throughgoing slot on one side of the duct, extending parallel to the travelling path. The suction apparatus further has a flexible cover belt which extends over the slot for sealing the inside of the duct from the environment and which defines an interstice within the truck. The interstice travels with the truck and provides a passage for the fiber from the opening mechanism to the inside of the suction duct.

Abstract: Two components, for example, conveyors, are interconnected by the intermediary of a connecting portion. The component connected to the connecting portion is shiftable along an alongate opening in the other component. The elongate opening is closable by means of a flexible web length which extends in the longitudinal direction of the elongate opening and in a loop about the connecting portion of the movable component. The connecting portion has guide means for successive lifting-out and laying of the web length respectively away from and towards the elongate opening on shifting of the connecting portion therealong.

Abstract: A door comprises two flexible door panels or sections wound on tubes on opposite sides of a door frame. Uprights at the free edges of the door sections are supported and driven in opposite directions by toothed belts driven by a driving shaft extending through one of the winding tubes, the other tube having a similar shaft driven in the opposite direction by a reversing mechanism, the tube of each flexible door section being connected to its shaft by a spring barrel maintaining the door section under tension.
