A magnetic track assembly including an elongate channel having an open side, an end wall, and two parallel side walls; a first magnet disposed within the elongate channel near an interior side of the end wall; a compartment defined within the elongate channel spaced from the first magnet; and a screen receiver disposed within the compartment and including a second magnet arranged facing the first magnet. In the magnetic track assembly, the first and second magnets are of opposite polarity and the screen receiver is loosely disposed within the compartment such that a magnetic bond is intact between the first and second magnets when the first and second magnets are close together and the magnetic bond is broken when the first and second magnets are pulled apart.

An improved door lock mechanism is a door locking device having heavy plates that sandwich the door frame above or below the door knob of a door with bolts passing through the plates to secure it to the door frame, and a barrel lock accessible through the outside plate with a barrel key. The locking mechanism is attached to a locking bar on the inside that is attached to a lock shaft rotatable on the door frame side which rotates downward into a slot formed in a plate that is attached to the inside of the door adjacent the frame plates. Together the frame plates, the door plate, and the rotating bar function as a door bar.

An embodiment of the invention provides a barrier support assembly for use in supporting a temporary safety barrier for rapid deployment in environments such as metro rail tunnels or construction. Further embodiments provide a barrier system and a method for deploying the barrier.

Protective glazing systems, apparatus, and associated methods for the protection of structural openings against impacts from projectiles from any cause, including nature or man. In some embodiments, the system may comprise a substantially unbreakable and clear or opaque panel, which may be at least substantially the same size (length and width) as the visible glass being protected, and may be anchored to the original glazing via standoff and/or anchor elements. Another embodiment may comprise a substantially unbreakable, ballistic-tolerant panel cut slightly larger than the visible original glazing being protected, said panel being attached to the structural opening via standoff and/or anchor means.

The invention concerns a cutting device (1) for reducing the width of a ready-made roller blind blank (28) comprising a roller tube onto which a fabric has been wound. The cutting device (1) comprises a mandrel (13), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel (13) such that the width of the ready-made roller blind blank (28) is reduced. The invention also concerns a ready-made roller blind blank (28), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device (1) according to the invention. For this the roller blind blank (28) comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank (28).

A system and method of training or modifying the behavior of pets and, in particular, dogs is disclosed and may include using scratch-resistant protector having adhesive and/or additive to protect the integrity of a door or other object. The adhesive may generally provide a securing or coupling relationship between an object and protector. The additive may provide a material that canines find unpleasant to smell, taste, touch, and/or scratch. In some implementations, the additive may be reapplied (e.g., if it wears off and/or otherwise diminishes in strength, quantity, quality, and/or overall effectiveness).
