Abstract: A locking assembly (20) that mechanically locks an attach- ment bolt (11), such as one used to secure a missile launcher (10) to an aircraft, for example, thus preventing the bolt from vibrating loose as a result of vibration experienced during flight. The lock- ing assembly has a spring loaded locking nut (23) that mechanically engages a hex head (24a) of an extension shaft (24) that is coupled to the attachment bolt. Transverse pins (22) permit axial movement of the locking nut but prevent rotation thereof. A socket is used to push the locking nut away from the hex head of the extension shaft, so that the attachment bolt can be loosened or tightened. When the socket is removed, a spring (25) pushes the locking nut over the hex head of the extension shaft, locking the attachment bolt and preventing it from turning.

Abstract: In a transmission for automobiles, the shift feeling is improved by smoothly transferring the operational load between a shift rod and a reverse shift fork. This is accomplished by cam faces formed on a reverse shift fork which shifts a reverse idle gear between a neutral position and a reverse position , and cam faces are formed on a drive cam which moves integrally with a shift rod. When the drive cam is moved from a neutral position to the reverse position, one of the cam faces presses against another of the cam faces moving the reverse shift fork in a circular manner in an anticlockwise direction, and the reverse idl e gear moves to the reverse position. When the drive cam member is moved from the reverse position to the neutral position, another of the cam faces presses against still another of the cam faces moving the reverse shift fork in a circular manner in a clockwise direction, and the reverse idle gear moves to the neutral position.

Abstract: A self-contained mapping and positioning system for underground mining is provided that is capable of mapping the topography of a region, such as a mine tunnel, and further being able to use the mapped data to determine the position of an object, such as a mining vehicle, within the mine tunnel. The system includes an inertial navigation system, a central processing unit, a three-dimensional database, a three-dimensional camera system, an operator console and a survey system having a three-dimensional laser scanner. The survey system using the three-dimensional laser scanner produces point cloud data, i.e., a set of data points representing the topography of the region. The point cloud data is stored within a storage device until the entire region is mapped and then transmitted to the operator console to be post processed.  After post processing, the data is exported to the three-dimensional database and the indexed for ease of use by the central processing unit. To determine the position of the object within the region, the system of the instant invention initializes the object in its current position.   The object is then either remotely or directly guided to another position from the current position where it is brought to an estimated position by the inertial navigation system or is remotely controlled for performing work, e.g., drilling a mine heading.  After a predetermined time of moving the object, there is an error in the position of the object and the operator console makes a call to the central processing unit on board the object to automatically calculate the true position based on the point cloud data stored within the database to update the position of the object. This is done by approximating a search range for the database according to t:he estimated position. A subset of data corresponding to the search range is removed from the database. The three-dimensional camera system then scans images of the surface in proximity to the object and converts the images to a patch of point cloud data. The patch of point cloud data is then matched against the subset of data corresponding to the search range of point cloud data removed from the three-dimensional database until there is less than a predetermined minimum error distance. At that point, the true position of the object is known. This new position is then put back into the inertial navigation system and the positional data of the object is updated with the correct positional data.

Abstract: Disclosed is an optical attenuator capable of increasing its dynamic range and reducing the temperature-dependence of the dynamic range.

Let x be an angle which is formed between the plane of polarization of a single incident light to the garnet single crystal, or the plane of polarization of one of two lights, whose planes of polarization intersect at right angles, and the direction of the magnetic field orthogonal to the optical axis, and let y be an angle which is formed between the polarizer and the analyzer, then the angle x is set to satisfy [(-z/2) + 90 x n] - 12 x [(-z/2) + 90 x n] + 12 (n = 0, 1, 2 or 3), where z y ~ 90; z is the angle of rotation of the plane of polarization caused by the Faraday rotational angle variable device.
