A method for providing an animated art experience to a user includes a user device receiving an image of an art piece selected by the user. The user device obtains information about the art piece. The user device presents a three-dimensional (3D) animated image that corresponds with the selected art image. Upon receiving an action by the user caused by a rotation or tilt of the user device, the user device provides a depth perspective view in correlation with the action and associated viewer angle of the art image such that further portions of the art image become visible. A background and a foreground of the image appear to move naturally as actions and associated viewer angles change.

A multilayer circuit board consisting of multiple circuit layers supported on sheets of PTFE or PTFE containing a fibrous stiffening agent, said circuit-bearing sheets being joined in fixed relative positions by means of separating layers of a adhesive unsintered tetrafluoroethylene resin.

Tetrafluoroethylene fine powder resins are described which have surprisingly high extrusion pressures and molecular weights which make them useful in post-paste extruded stretching operations. The resins are made by using a manganese triacetate/selected reducing agent polymerization initiator and controlling its rate of addition.

A claw hammer having a protective cushion attached to the hammer head so that during normal usage it is in a resting position which will not interfere with the nail driving (or pounding) function of the hammer but at least a portion of the protective cushion is movable into a working position over the bell end of the hammer in order to prevent or minimize damage to the nail bearing surface when the claw end is used for nail pulling. The means facilitating movement of at least a portion of the protective cushion may be either a slide mechanism or a pivot point, such as a hinge, fold or bend. The protective cushion may be made of leather, rubber, synthetic rubber, plastic or other materials.

It has been discovered that if a selected water-soluble aluminum, magnesium or zinc salt of a monovalent anion is added to an aqueous dispersion of a non-melt-fabricable tetrafluoroethylene polymer wherein the dispersion has a pH of 4 or less, the resulting dispersion will flow well on a woven fabric substrate, such as a woven glass fiber fabric, and will fill and cover the interstices of the weave without the necessity of having filler particles present.

A flanged wedge having a wedge body of conventional design with two to four flanges extending from the parallel planar surfaces of the wedge body. The wedge is used to separate the kerf of a board being cut to prevent binding of the saw. The flanges keep the wedge in position during the cutting and support the sides of the board at the cut end until the sawing is completed. Various flange sizes and shapes may be used.
