Abstract: An apparatus for reinforcing door jambs to prevent forced entry through the doorway by strengthening the composite materials of the door jamb with the addition of the apparatus, which is attached with threaded fasteners that go through the door jamb and are anchored into the framing studs. The device is made of 14 gauge ASTM, A-36, Mild Steel with holes through which the latching and locking mechanisms of the door may pass, as well as smaller beveled holes to pass screws through to attach the device to the door jamb and framing studs. The device is also formed so as to facilitate latching mechanism closure. This device can also be used to assist in the repair of damaged door jambs by holding together the damaged portions once they are placed back in position.

Abstract: A String Alignment Plate for stringed instruments to reduce the excess friction in that portion of the string in the head region, generated at the nut of the instrument as a string passes through a notch of the nut and then bends in order to align with the tuning pin or machine head. The additional friction is created at the point of the bend where the string rubs excessively against the nut. This friction impedes tuning and results in differential tension of the string on either side of the nut. The String Alignment Plate is affixed to the head of the instrument and keeps the portion of the string in the head area in-line or parallel with that portion of the same string as it extends from the bridge to the nut, thus removing the bend. Once the string reaches the String Alignment Plate, the string curves around the Peg on the String Alignment Plate to the tuning peg or machine head.
