Cord tensioning systems are provided for top down/bottom up coverings to prevent entanglement of lift cords about associated wrap spools by correlating rotation of the wrap spools with translating threaded nuts mounted on threaded shafts rotating in unison with the wrap spools whereby abutment of nuts associated with lift spools prevent over movement of rails associated with the spools and thus entanglement of the lift cords associated therewith.

A horizontally retractable covering for an architectural opening includes a headrail supporting a collapsible panel of material, a fixed rail securable to a side of the architectural opening and to a side edge of the panel, and a movable rail secured to the opposite side of the panel while being movable along the length of the headrail. An improved trolley connecting the top end of the movable rail to the headrail is provided so as to permit uniform gathering of the panel material along the horizontal extent of the trolley for improved aesthetics when the panel is fully extended across the architectural opening. A stabilizing cord system maintains a parallel relationship of the movable rail to the fixed rail to assure desired movement of the movable rail while permitting the aforenoted uniform gathering of the panel material.

A control system for a top down/bottom up covering for an architectural opening includes a common drive shaft for raising and lowering a middle rail and a bottom rail between which a flexible shade material extends. A control element operates a spool lift system and a roller lift system, with the spool lift system being associated with the middle rail and the roller lift system being associated with the bottom rail. The lift systems are sequentially operated when the drive shaft is driven in either direction by the control element.

A system for suspending a free-hanging shade material in an architectural opening includes a panel of shade material and brackets that can be mounted to the top edge of the framework around the architectural opening even when the top edge is not straight or horizontally disposed. The top edge of the panel has reinforcement strips operatively connected thereto which are releasably connected to the brackets. The system is useful in conventional rectangular architectural openings or openings of unusual shapes and sizes such as semi-circular or having an inclined top edge.

Flowable, pressure-compensating material compositions are provided. The compositions are directed toward improving one or more aspects of the flowable material, such as by providing/improving flame retardancy and/or the homogeneity of the composition over time. For instance, one composition includes a liquid, a viscosity-increasing material, and beads having a preselected coating thereon to provide for a coupling interaction with at least one of the liquid and the viscosity-increasing material.

A flame-resistant, flowable, pressure-compensating composition is provided. The composition can include a flame retardant such as boric oxide, boric acid, borax, bicarbonate of soda, epsom salt or mixtures thereof. The remainder of the composition can include silicone oil, glycerin or a wax/oil material.
