Abstract: Disclosed is a brace bar attached to an inner surface of a sound board of a guitar to prevent the sound board from being distorted, which has a modified shape to improve the flexibility of the sound board while maintaining the strength of the sound board, thus improving the resonance of the sound board and reducing a weight of the sound board. The brace bar includes a narrow portion having a cross-section with a profile of which at least one side extends vertically upward to a position of a predetermined height, thus forming a lower base part, and is bent inward at the position toward a center of the brace bar, and, thereafter, extends upward while being inclined at a predetermined inclination angle to form a tapered upper part.

A shell ram having a loading tray is disposed on a free end of a shell transfer arm that is pivotable between a raised position, in which the loading tray is aligned with the gun bore axis, parallel to a plane of elevation, and a lowered position, in which the tray is essentially vertical. A gripping mechanism on a shell transport arm grasps a vertical shell stored in at least one ammunition magazine for supplying a shell from a shell transporter, to the loading tray, in the lowered position of the shell transfer arm. The ammunition magazines and transporter are disposed in the housing ahead of a trunnion. The loading tray is pivotable about a pivot axis, which is essentially vertical in the lowered position of the shell transfer arm, by at least 180° between a receiving position opening ahead of the trunnion, and a delivery position opening behind the trunnion.

Abstract: A motor-driven power steering unit comprising an electric motor for producing an auxiliary steering force in a steering system coupling a steering wheel to two wheels of a vehicle. The steering system provides assistance, based on steering information, to a rotation of the steering wheel by control of an electric current fed to the electric motor. A steering angle detection device is provided, wherein the steering system regulates the assistance as a function of a steering angle detected by the detection device. The assistance, or current, is reduced after a pre-set or pre-definable angle is reached or exceeded prior to reaching a respective end position. The reduction of the assistance or current is cancelled as soon as signs of steering force and the steering angel no longer coincide.
