Abstract: A superimposing apparatus and method for broadcasting a 3DCG image can calculate and superimpose additional information such as characters and figures expressed by a 3DCG image on a TV frame in real time by means of combining a general three-dimensional graphics accelerator board and a conventional TV broadcasting hardware and devising a software processing. The superimposing apparatus for broadcasting a 3DCG image includes a rendering process for rendering a 3DCG image datum by a three-dimensional graphics accelerator and a mixing process for mixing a 3DCG image and an input TV signal by a superimposer. The rendering process is carried out concurrently with the mixing process. A frame to be mixed is a previous frame advanced by one frame from a frame to be concurrently rendered. A system memory to be read out is changed to even frames and odd frames in accordance with an input TV signal so as to avoid an interference of rendering and superimposing.

Title: A bushing including a terminal ear and a method of manufacturing the bushing
Inventor: SULLIVAN TIMOTHY A
IPC: C03B37/09
Filed: 2001-03-16
Granted: 2010-06-29
Abstract: A bushing (10) including a terminal ear (100, 102) and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body (11) which can include side plates (12, 14), end plates (16, 18), a bottom plate (20), and terminal ears coupled to the bushing body. Clamps (200) are attached to the terminal ears to supply electrical current to the bushing to maintain the glass inside in a liquid state. Each terminal ear includes an upper portion (110) and a lower portion (120). The upper portion is coupled to a side plate of the bushing. A clamp is attached to the lower portion of the terminal ear. The upper and lower portions are oriented at an angle with respect to each other. Support portions (130, 132, 134, 136) are provided along the side edges of the upper portions of the terminal ears. Support portions stiffen the terminal ear, thereby increasing its resistance to bending and fatigue stresses. Support portions do not contact the bushing and therefore do not directly conduct current to the bushing. Accordingly, the temperature of the support portions during operation of the bushing will be lower than the conducting portion of the terminal ears. Since the support portions operate at a lower temperature, the thermal degradation of the terminal ear is reduced.

Abstract: A combined degassing and flotation tank for separation of a water influent containing considerable amounts of oil and gas. A rotational flow is created in the tank which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall where they coalesce and rise to the surface of the liquid and are removed via the outlet (3) whereas the heavier parts are forced down where the heavy particles sink to the lower part where they may be removed as a sludge. The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gasses from water streams before the water is returned to the sea.

Abstract: An imaging system uses 'RF daylight' created by an RF illumination source, such as a television broadcast tower, to passively generate RF scattering coefficients for multiple points within a prescribed three-dimensional volum e being illuminated by the RF transmitter. The scattering coefficients provide a complex interference pattern having amplitute and phase components that contain all information necessary to recreate a three-dimensional monochromatic image of the illuminated scene. Coherent complex correlation provides scene information content that is only a function of scene scatteri ng and collector geometry.
