    Abstract: A real time computer image generation system incorporating comprehensive distortion correction in which a predistorted image is computed and placed on a projection raster prior to projection onto a view screen in order that the image as seen by a viewer appears correct. A method for implementing comprehensive distortion correction in real time utilizes fixed transfer characteristics of a projection lens coupled with scene by scene translation of each of a plurality of predetermined points from a projection raster to a location on a view screen. Each image is divided into a plurality of spans and the span corners are mapped from the projection raster to the view screen. The location of image vertices on the view screen are determined with respect to the viewer and the vertices are mapped to corresponding locations on the projector raster. An image is then generated by locating the spans within which each of the vertices is positioned and constructing an image on the projection raster using the map span corners in viewer space and the mapped vertices in projector space. The reconstructed predistorted image is then projected onto the view screen so that it appears correct to a viewer.

    Abstract: A first annular form (4) used for making a transformer core is wound from a strip of amorphous ferromagnetic material and is thereafter cut. The resulting laminations are then arranged in a second annular form (10) with distributed gap joints in region (17), each joint involving a plurality of superposed lamination. The second annular form (10) is then formed into a rectangular shape core and is then annealed. Then a bonding agent (26) is applied to the transverse edges of the laminations over a region of the core removed from the joints. The joints are then separated to open the core, allowing displacement of unbonded regions of the core. Thereafter, preformed coil structure (28) is inserted into the window of said open core to surround a portion of the core. Then the unbonded regions of the core are returned to their original positions to remake the joints.

    Abstract: Chloroformate compositions, particularly bischloroformate compositions, are prepared by the reaction of phosgene with a hydroxy compound, preferably a dihydroxy compound such as bisphenol A, in a heterogeneous mixture, while adding a hydrogen chloride scavenger comprising aqueous base as necessary and maintaining a pH of 0.5-8 during the phosgene addition. When a polyhydroxy compound is employed and the temperature is above 30oC, the phosgene addition rate is maintained at a level high enough to effect rapid and complete reaction with dissolved hydroxy compound. This method uses substantially less phosgene than methods involving a higher pH.

    Abstract: A gun capable of operating at relatively higher temperatures. The barrel of the gun is made up of at least two layers. The inner layer (22) is of a refractory material which may be a metal refractory or a non-metal refractory. The liner (28) is bonded to an outer jacket material formed of an alloy of nickel, aluminum and molybdenum. The coefficient of expansion of the liner (28) and of the jacket are relatively low so that the gun does not expand extensively when heated by intensive use. The jacket metal is of higher strength at elevated temperature than is the conventional gun barrel steel.
