Inventor: KLEIN KEVIN JOSEPH
IPC: B06B3/00

Abstract: A horn for coupling high frequency vibrations from an electroacoustic converter unit to a workpiece, such as is used for welding thermoplastic workpieces by ultrasonic vibrations, is constructed by machining sections (10a, 10b) of the horn and welding the sections (10a, 10b) together using electron beam welding or laser beam welding. The respective sections (10a, 10b) can be made from bar or plate stock. This construction eliminates the machining of deep, inaccessible slots, and as most of the surfaces to be machined are accessible, a fine surface finish can be provided, thus eliminating tool marks which cause the existence of areas of high mechanical stress concentrations when the horn is rendered resonant. Also significant economic advantages are achieved when manufacturing large, massive slotted horns in this manner.

Abstract: Over tightening of the threaded rods (36, 38, 40, 42) used to engage and remove the cement for prosthetic joints is avoided by measuring the depth of the passages into which the rods (36, 38, 40, 42) are threaded and providing sleeves (28, 30, 32, 34) on the rods (36, 38, 40, 42) which serve as visual indicia of the extent of penetration of the rods (36, 38, 40, 42) into the cement. A depth gauge (20) calibrated in both units of length and screw thread turns is provided for the measuring function. The sleeves (28, 30, 32, 34) are slidably received on the rods (36, 38, 40, 42) and proportioned to engage the edges of the passages into which the rods (36, 38, 40, 42) are threaded. In use, the sleeves (28, 30, 32, 34) slide toward a marker as the rods (36, 38, 40, 42) are threaded into place

Abstract: An interactive computer graphics display system processing method is disclosed for identifying a displayed primitive that intersects an operator selected area (30) of the display screen (32). Pursuant to the method, the operator selected area (30) of the display screen (32) is reverse mapped to world coordinate space (34); data representative of displayed geometric primitives is then clipped against the reverse mapped selected area (36) in world coordinate space (34); and clipped data representative of displayed geometric primitives that intersect the reverse mapped selected area are identified for operator defined application processing. Further processing steps include mapping of the identified data to screen coordinate space (32) and rasterization of the data for display in the screen monitor. A zoom processing method is also provided wherein an original operator defined zoom window (30) is transformed from screen coordinate space (32) to world coordinate space (34) and the boundaries of the transformed window in world coordinate space (36) are utilized as data clipping boundaries. After clipping, data representative of a displayed geometric primitive outside the inverse mapped zoom window is discarded, thus preventing the rerasterization of geometric primitives outside the zoom window. Further processing includes mapping of the identified data to a defined zoom window in screen coordinate space (32) for operator viewing and selection of a particular geometric primitive for application processing.

Abstract: The invention relates to a subwarhead which is arranged to be separated from a missile, for example a carrier shell or the like, over a target area. The subwarhead comprises an active part, a target detector and an arrangement which imparts a rotation to the subwarhead for scanning of the target area in a helical pattern during the descent of the subwarhead towards the target area, the target detector being arranged displaceably in order to allow a free view at the side of the active part. Two diametrically situated aerofoils (1, 2) are arranged to be pivotable, each on its own shaft (4, 5), which shafts are situated in a plane which is at right angles to the axis of symmetry of the active part, from a folded-in position, in which the aerofoils connect with the outer surface of the subwarhead, to a position folded out by 90°, in which the two aerofoils form a braking area for the rate of descent of the subwarhead.

Abstract: A radiation source (12, 216) rotates around a patient on a patient couch (30, 212) as the couch is advanced through an examination region (14, 214). Radiation detectors (24, 230) detect radiation that has passed through the patient along rays of a plurality of fan shaped views. Each view is identifiable by its angular position φ around the examination region and its longitudinal position R in the spiral and each ray is identifiable by its angular position β in the fan. An interpolator (46) interpolates views collected over more than two revolutions of spiral path using an interpolation function (62, 94). A set of interpolated views is reconstructed (54, 250) into a series of image representations representing parallel planar slices through the imaged volume. In some reconstructions, particularly reconstructions in which a 180° based reconstruction algorithm is used or the energy of the x-ray beam is varied, the filter function (82, 84, 86, 116, 118) is varied from ray to ray within each view. A projection filter can also be varied from view to view in order to emphasize structures along various axes of a subject. A cardiac or other physiological condition monitor (90) monitors for movement of the subject so that one or more of the rotational speed of the x-ray source (12, 216), movement of the patient couch (30, 212), energy of the x-ray beam, or filter function can be varied accordingly.
