Abstract: Abstract An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by the extraction or insertion of spaced apart rows and lines of picture elements, at positions which are the closest approximation to the newly scaled base, whether smaller or larger.  In reproducing a given image, for example, the image may be concurrently or successively scanned by an array of photo detector elements and a plurality of digitally valued picture elements corresponding to grey scale values across the image, and distributed with a given resolution, may be generated. These values may be processed in real time, or stored in a comparable array for subsequent processing.  In either event, the number of rows and lines in the array are modified in accordance with the desired scale factor, and these discrete changes are introduced at the closest approximation to optimum positions.  In enlargement, the added lines are duplicative of the next adjacent line, whereas in reduction the lines are simply deleted and subsequent lines of picture elements are shifted to close the gaps and provide a continuous image.  A dot generator array, such as an ink jet array, responsive to the digital values of the picture elements, operates in scanning fashion across a copy sheet and generates the image, at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued picture data to a different loca-tion.  However, other conventional image reproducing systems such as a cathode ray tube, electrostatic or thermal recording system may be utilized.

Abstract: SKIN-FLOW CONTROL RAZOR        ABSTRACT      A shaving assembly is provided with skin-flow control means posi-tioned in advance of the blade edge to control the effective exposure and blade-to-skin angle of the blade edge so as to greatly minimize or eliminate nicking.  The skin-flow control means serves to minimize or eliminate the skin bulges which may otherwise be created in the unsup-ported space between a razor guard element and the blade edge.  The skin-flow control means is provided by extending the skin-supporting surface of the guard element into such close proximity with the blade edge that the formation of a skin bulge therebetween is substantially prevented.  A plurality of small holes may be provided in the guard element near the blade edge for allowing water flow therethrough to rinse shaving debris from the region of the blade.

Abstract: ABSTRACT OF THE DISCLOSURE A hollow gas turbine vane is shown enclosing, in spaced relation, a vane insert for receiving cooling air. The insert has a plurality of apertures for selectively directing jets of the cooling air against the internal walls of the vane.   A portion of the air is discharged from within the vane chamber through a slit in the trail-ing  edge  which  contains  cooling pins  extending  trans-versely  thereacross  to maintain  the  slit  dimensionally stable and also induce turbulence in the exhausting cool-ing air to  improve its cooling effectiveness.   Certain apertures in the insert adjacent the trailing edge are selectively directed to cause jets of the cooling air to impinge at the base of certain of the pins in the inlet area of the slit to promote turbulence in the air entering the slit and adjacent the internal  face,  thereby maxi-mizing heat transfer from the slit walls to the air.

Abstract: ABSTRACT       In an assembly, for use in transducer type instruments such as accelerometers, having a position sensing movable member including a pick-off element, wherein the movable member is secured to a support member by a flexure or hinge and the support member in turn is cantilevered between two stator members, instrument bias errors resulting from the securing of the non-cantilevered portion of the support member between the stator members can be reduced by aligning the edges of the surfaces of the stators that contact the support member with the centroid of the pick-off element so that the axis of cantilever rotation passes through the centroid of the pick-off area.  In transducers having electrical leads on the movable member, the flexure and the support member for electrically connecting the pick-off element to the support member, bias errors can be further reduced by including the area of the electrical leads in calculating the centroid.
