Abstract: Abstract Diffuser For Gas Turbine Engine A diffuser system for a gas turbine engine includes a prediffuser and a piping system that diverts the flow into two streams.  One stream captures the prediffuser discharge air at the center of the gas path where the total pressure is at its highest level and provides an additional stage of diffusing before dumping it around the burner to supply liner cooling air, turbine cooling air and if necessary, small amounts of dilution air to trim radial temperature profile.  The other stream is ducted directly into the burner avoiding the typical dump diffuser losses.

Abstract: ABSTRACT OF THE DISCLOSURE    An internal seal is provided for a universal joint, which seal is more effective in retaining lubricant and in preventing the ingress of water and contaminants.  More specifically, the universal joint includes a cross having a body and trunnions extending therefrom. Each trunnion is received in a bearing cup having an open end with an internal annular shoulder near the open end.  The universal joint seal comprises a resilient sealing member having at least two inner circular lips which engage the trunnion near the cross body and at least two outer circular lips which engage the internal surface of the bearing cup between the open end and the annular shoulder.  The sealing member further includes an additional lip which engages the annular shoulder and a spaced additional lip or ridge which engages the body of the cross adjacent trunnion.  The latter two lips serve to position the sealing member with respect to the cross and bearing cup with the sealing member being substan-tially enclosed by the bearing cup, which minimizes the possi-bility of damage to the sealing member.  The internal universal joint seal provides a total of at least three seals between the sealing member and the cross and also between the sealing member and the cup to contain lubricant in the cup and to prevent the ingress of water and contaminant.  In one form, the sealing member also has a longer lip which extends over upper ends of needle bearings located between the trunnion and cup to aid in retaining the needle bearings in place when the cup is separated from the trunnion.

Abstract: ABSTRACT OF THE DISCLOSURE      A parallel vector processor is disclosed.  In order to increase the performance of the parallel vector processor, the present invention decreases the time required to process the elements of a single vector stored in a vector register.  Each vector register of a plurality of vector registers is subdivided into a plurality of smaller registers. A vector, stored in a vector register, comprises N elements; however, each of the smaller registers store M elements of the vector, where M is less than N.  An element processor is associated with each smaller register for processing the M elements of the vectors stored in the smaller register and storing a result of the processing in a result register.  Each of the smaller registers of the vector registers, and its corresponding element processor, comprise a unit.  A plurality of units are connected in a parallel configuration.  The element processors, associated with each unit, have been loaded with the result, the result being stored in a result register.  Each of the results are processed in parallel fashion, as a result of the parallel configuration of the plurality of units. Therefore, the time required to process the elements of a single vector, stored in a vector register, is decreased.

Abstract: METHOD AND APPARATUS FOR KNIFE AND BLADE SHARPENING          ABSTRACT       An apparatus for sharpening knives, and the like where fixed abrasive elements on an orbiting surface in contact with the knife cutting edge facet move in a mechanically generated uniform cyclic orbit of circumference less than about one inch and through that motion provides the work and energy to sharpen the knife or blade edge.  The apparatus provides a circumferential velocity of the abrasive element of less than 800 feet per minute and restrains motion of the abrasive surface to less than + .005 inch in a direction perpendicular to the intended plane of the knife or knife edge facet.  The apparatus contains novel magnetic and other means to steady, guide and control position and angle of the face of the blade relative to the orbiting abrasive elements, to realign any burr or sharpening debris on the knife edge, to control in part the abrading forces, and to remove sharpening debris from the abrasive surface and sharpening zone.  A means used to create the orbital motion of the abrasive surface utilizes a pair of synchronously driven eccentric cranks that engage an orbiting drive plate that supports the abrasive surface or surfaces, where the eccentric cranks are mounted on or are an integral part of the shafts of two gear pulleys driven syncronously by means of a motor-driven timing belt, and where the supporting drive plate is constrained to orbit in a prescribed principal plane by means of fixed bearing support points.
