Inventor: LEWIS J HARRY
IPC: E01C19/20
Filed: 1994-06-16
Abstract: A salt spreader mounting assembly that attaches to the rear of a utility vehicle such as a conventional pick-up truck is described.   The salt spreader mounting assembly includes a frame, a means for attaching said frame to the vehicle, and a pivoting means such that the frame can swing horizontally thereby permitting access to the rear of the vehicle, without interference with the tailgate.  The frame supports a compatible salt spreader/hopper unit.  The assembly allows a combination spreader/hopper to be swung away from the vehicle from at least one of its sides, thereby allowing direct access to the rear cargo area via the tailgate.  The assembly is easily installed or removed and requires limited modification to the vehicle.

Title: Method for determining the line-of-sight rates of turn with a rigid seeker head
Inventor: ZACHARIAS ATHANASSIOS
IPC: F41G7/22
Filed: 1994-11-08
Abstract: ABSTRACT         Output signals from a seeker head rigidly mounted on the missile are used to make a gimbal suspended and gyro-stabilized virtual seeker head track the line of sight.  The virtual seeker head represents the mathematical model of a gimbal mounted and gyrostabilized seeker head in the computer.  The virtual seeker head's follow-up simulation taking place at the same time as the motion of the missile permits determination of the rate of turn of the missile/target line of sight.  Azimuth and elevation deviation angles of the target, measured in the rigid seeker head, are converted to the azimuth and elevation deviation angles of the virtual seeker head.  The virtual seeker head tracks the line of sight with a first-order (or higher) time response.  The motions of the virtual seeker head calculated by the software yield the rates of turn of the virtual seeker head in the inertial system or, with earth-fixed application, in the geodetic system which enter the guidance algorithm.  From the rates of turn of the virtual seeker head one also determines the particular attitude angles of the virtual seeker head, i.e. its angular position in the inertial system, this is required for converting the attitude angles from the rigid to the virtual seeker head.  The missile follows the guidance commands, changing its position and attitude, which in turn changes the deviation angles in the rigid seeker head.  These angles are converted to the virtual seeker head again.  This closes the loop.

Patent CA-2141718-A1 (CA)
Inventor: SERAFINI TITO T
IPC: C07D209/48
Filed: 1995-02-02
Abstract: A method for forming a homogeneous, concentrated, prepolymer composition, and a method of using the concentrated prepolymer composition to uniformly coat fibers is described. The prepolymer mixture is formed by dissolving a dialkyl, trialkyl, or tetraalkylester of biphenyltetracarboxylic acid in a solvent comprising ethyl acetate and methanol in a molar ratio of from about 1:3 to about 1:60, to form an ester solution. Diamine and end cap compound are added to the ester solution to form a monomer mixture solution. The end cap compound is a divalent compound characterized by (i) at least one unsaturated moiety, (ii) capable of reacting with the diamine or the ester to form an end cap radical that precludes further reaction of the diamine with the ester, and (iii) capable of undergoing addition polymerization. A portion of the solvent is evaporated from the monomer solution to form the substantially homogeneous, concentrated, prepolymer composition. The concentrated prepolymer composition is used to uniformly coat fibers by heating the composition to an elevated temperature to form a prepolymer melt and applying the prepolymer melt to fibers. An article of manufacture comprising fibers and polyimide can be formed by heating the prepolymer coated fibers to the cross-linking temperature of the prepolymers.

Abstract: Method and apparatus for a filtered stream buffer coupled to a memory and a processor, and operating to prefetch data from the memory. The filtered stream buffer includes a cache block storage area and a filter controller. The filter controller determines whether a pattern of references hasa predetermined relationship, and if so, prefetches stream data into the cache block storage area. Such stream data prefetches are particularly useful in vector processing computers, where once the processor starts to fetch a vector, the addresses of future fetches can be predicted based in the pattern of past fetches. According to various aspects of the present invention, the filtered stream buffer further includes a history table, a validity indicator which is associated with the cache block storage area and indicates which cache blocks, if any, are valid. According to yet another aspect of the present invention, thefiltered stream buffer controls random access memory (RAM) chips to stream the plurality of consecutive cache blocks from the RAM into the cache block storage area. According to yet another aspect of the present invention, the stream data includes data for a plurality of strided cache blocks, wherein each of which these strided cache blocks corresponds to an address determined by adding to the first address an integer multiple of the difference between the second address and the first address. According to yet another aspect of the present invention, the processor generates three addresses of data words in the memory, and the filter controller determines whether a predetermined relationship exists among three addresses, and if so, prefetches strided stream data into said cache block storage area.
