An access panel for an opening in a duct is provided. The access panel includes an exterior and an interior. The access panel further includes a section positioned on the interior and having a profile substantially corresponding to the opening in the duct. A plurality of fasteners is positioned about the section. Each fastener has a dip configured to move to a position defined to extend away from the profile of the section on the interior. When the access panel is positioned with the section on the interior against the opening in the duct and the fasteners are moved to the locking position the clips rotate to extend over the profile and secure a portion of the duct adjacent to the opening against the interior of the access panel.

A trash container locking apparatus includes a housing which is secured to a surface of a trash container. The housing includes a pivot member rotatably mounted in an outer wall of the housing for rotation about a pivot axis and having an inner portion inside the housing and an outer portion outside the housing. A latch member is secured to the pivot member inside the housing. A swing arm secured to the pivot member outside the housing and associated with a locking bar which extends over a lid of the trash container. A latch paddle is pivotally mounted in the housing to hang vertically in a latch engaging position when the housing is mounted on the trash container. The latch member and latch paddle have interengaging formations which engage in a locking position to prevent the latch member and associated swing arm from rotating.

Structure for maintaining a sliding window sash at an intended position with respect to a frame within which the sash moves. The structure serves to retain the sash at a position along an axis generally perpendicular to a plane defined by the window frame. An inwardly facing surface of the frame has formed therein an elongated trough which extends generally parallel to a direction of intended sliding movement of the sash. A blade is mounted within a cavity in the sash and disposed for pivotal movement between a first position, wherein the blade is retracted within an outwardly facing surface of the sash, and a second position, wherein the blade is extended through the outwardly facing surface of the sash into the trough defined within the inwardly facing surface of the frame. The blade is normally biased to the second position, but it can volitionally be retracted to the first position to enable tilting inward or removal of the sash from the window frame.

A lock for a container lid which comprises a retractable U-shaped handle secured for movement within apertures in a side of a container and a U-shaped handle which is fixed to the container lid. In closing of the container lid, the lid is closed with the fixed U-shaped handle straddling the retractable U-shaped handle in a retracted position. When the lid is in place, the retractable U-shaped handle is pulled outwardly and the retractable U-shaped handle is secured by some lock means to the U-shaped fixed handle. Thus, the container lid cannot be opened until the lock is removed.
