Abstract: Films having a structured surface with an engineered feature, such as prism grooves, to be used in displays having a backlight. The films can be arranged in a stack having one or more of the following: birefringent brightness enhancement films, non-birefringent brightness enhancement films, polarizers, diffusers, birefringent turning films, and non-birefringent turning films. Those films can be arranged in any order from the backlight to a viewer.

Abstract: A rotary bristle tool having a backing with a plurality of bristles extending therefrom. The bristles have a cross section and preferential orientation to control deflection during rotation of the tool. One embodiment is well suited for refining the inside surface of two-way and three-way corners. The backing and bristles are preferably integrally molded. The rotary bristle tool is molded from a moldable polymer such a thermoset polymer, thermoplastic polymer, or thermoplastic elastomer. The rotary bristle tool can include an attachment member molded integrally with the backing. Also disclosed is a method of making a rotary bristle tool and a method of refining a workpiece surface with a rotary bristle tool.

Abstract: An adjustable socket-forming device (10) is disclosed that is adapted for use with a ratchet (26) or other tool to form an adjustable socket wrench. The socket-forming device includes a body (12), a movable gripping member (60) slidably mounted by the body, and a screw (80) for securing the movable gripping member at a selected position with respect to the body. The body includes a fixed gripping member (30) shaped so as to define a first group of faces (34, 36) of a polygonal socket, and the movable gripping member is shaped so as to define a second group of faces (66, 68) of the polygonal socket. The movable gripping member is slidably mounted by the body such that the first and second groups of faces are opposed, and such that the movable gripping member is movable with respect to the body to vary the distance between the groups of faces. Securing the movable gripping member at a selected position with respect to the body thereby defines a socket of a selected size.

Abstract: A mechanical security device for preventing disconnection between first and second objects. The first and second objects include a nut rotatable with respect to the objects in one direction to connect the objects and in an opposite direction to disconnect the objects. In one embodiment, the security device comprises a guard collar and a locking bar. The guard collar is adapted for positioning around the nut to prevent it from being accessed for rotation. The locking bar is adapted to prevent substantial rotation of the guard collar with respect to the first object, and to limit axial movement of the guard collar to a degree sufficient to prevent the nut from being accessed for rotation. The security device is particularly suited for preventing removal of a regulator from a compressed gas cylinder.
