Patent EP-0040158-B1 (EP)
Title: A scanning grid apparatus for suppressing scatter in radiographic imaging
IPC: G21K1/02
Filed: 1981-05-13
Granted: 1986-04-23
Abstract: A scanning grid apparatus exhibiting high primary and low secondary X-Ray transmission of X-Ray radiation emitted from an X-Ray source defining a focal spot, including at least one scanning grid provided with top and bottom pairs of opposed grid slat retainers disposed in parallel planes. Pivotably attached between the top pair of retainers is a plurality of radiopaque linear or wavy grid slats separated at predetermined distances in the plane of the top pair of retainers. The bottom pair of retainers includes spacers for maintaining the grid slats separated predetermined distances within allowable limits in the plane of the bottom pair of retainers. The separation distances provided by the bottom pair of retainers is chosen as the geometric projection of the separation distances in the plane of the top pair of retainers from the source focal spot to the plane of the bottom pair of retainers, such that each of the grid slats is focused on the focal spot of the X-Ray source. The pairs of grid slat retainers are mechanically coupled to the source focal spot by means of a slotted linkage arm capable of moving the pairs of grid slat retainers linearly in the direction transverse to the plural grid slats to blur out and render invisible slat shadows which would otherwise appear on an image receptor, while nevertheless maintaining the grid slats focused on the source focal spot to reduce primary radiation cut-off. A pair of scanning grids in which the grid slat retainers of the respective grids are arranged orthogonally may be staggered between a subject and an X-ray image receptor to further suppress secondary radiation.

Abstract: Boron rich cubic boron nitride suitable for use in electroplating processes (e.g. nickel plating) has been made by an acid leaching process. Boron rich aggregated cubic boron nitride grinding grits are leached in a mixture of nitric and sulfuric acids, the following conditions being typical; (a) volume ratio of 67% nitric acid to 98% sulfuric acid of 10:20; (b) temperature of 250 DEG  C; and (c) for a time of 1 hour. The process removes sufficient free surface boron to reduce the conductivity at the surface, resulting in an abrasive which does not overplate. FIG. 1 is a photomicrograph of a typical plated surface containing the improved CBN grinding grit of this invention, and FIG. 3 is an X-ray diffraction pattern characteristic of this new product.

Abstract: Configurable semiconductor integrated circuits as-made each have a plurality of logic circuits formed at discrete sites (10S). For each logic circuit, direct selectably conducting/non- conducting connection paths (14A,B,C,F) extend from its output to input of a first set of other logic circuits and to its inputs from outputs of a second set of other logic circuits. All of the sets for all of the logic circuits are each different. Other direct connection paths (50R,50C) are selectably connectable to inputs (14D,E) and outputs (52G,H) of the logic circuits. Selection can be irreversible (Figure 8) or reversible (Figures 9, 10, 11, 18) and involves coincident signal addressing (22R,C) of the sites (105) and coded configuring ofthe paths at that site. Reversible selection can beviafield effect transistors or bipolar transistors and can be at or near normal logic signal levels and speeds (Figures 11 and 18). Versatile configurable input/output arrangements are described (Figures 13-16), also reconfigurable data processing systems using the reversible transistor provisions (Figures 20-23).
