Abstract: A suspended ceiling system in which the grid runners are largely concealed by the panels to produce a distinctive high quality appearance. In various illustrated embodiments, the visual effect is produced as a result of the panels being separated by a relatively narrow gap in two perpendicular directions or by a narrow gap in one direction and essentially no gap in the perpendicular direction, and the grid being recessed above the main face of the panels. The panels are accurately positioned on the grid by metal clips, normally permanently attached to the panels, which engage upstanding flange portions of the grid runners. The accurate positioning afforded by the clips assures that visually distracting variations in the size of the narrow gaps are avoided. The clips can also serve to avoid accidental dislodging of the panels.

Abstract: This method and apparatus contemplate the making of pocketed springs for mattresses and cushions by inserting compressed springs at intervals along and between the plies of a folder two-ply strip of sheeting, maintaining the springs compressed therein while seaming the edges of the plies to form a sleeve about the compressed springs as the strip is drawn lengthwise toward a release point at which each spring is free to expand to spread the plies. This transposes the edge seaming to mid-height of the spring. A previously made cross seam incorporating the transposed edge seaming limits the forward movement of the spring and a further such cross seam made behind the spring encloses the spring within an individual pocket of the sleeve. The repetition of spring release and cross seaming behind each spring released produces a string or chain of pocketed springs with the closing seam of the sleeve at mid-height of the springs.

Abstract: A quick coupler for coupling an implement to a work machine is provided with a control system that substantially prevents inadvertent and unintended release of the implement from the machine. Inadvertent and unintended release of the implement is prevented by requiring two separate switches to be actuated to release the implement. Actuation of one switch supplies pressurized fluid to a fluid circuit connected to an actuator operable to release the implement from the machine. However, the pressurized fluid supplied in response to actuation of the one switch is not sufficient to activate the actuator. Concurrent actuation of a second switch raises the pressure of the fluid supplied to the actuator fluid circuit to a level sufficient to activate the actuator, thus releasing the implement.
