Abstract: Abstract An acoustic surface wave signal processor comprises a substrate for propagating acoustic waves at a surface thereof.  A first transducer launches an acoustic wave along a first propagation track at this surface.  First and second spaced apart reflectors disposed at opposed ends of the first propagation track define a first resonator. A second transducer receives an acoustic wave along a second propagation track at the surface.  Third and fourth spaced apart reflectors disposed at opposed ends of the second propagation track define a second resonator.  Fifth and sixth reflectors respectively cooperating with the first and second resonators form a third propagation track along the surface intersecting the first and second propagation tracks whereby acoustic wave energy is coupled between the first, second, and third propagation tracks. Seventh and eighth spaced apart reflectors at opposed ends of the third propagation track define a third resonator. This arrangement provides an improved technique for forming surface wave resonators on temperature stable media, hence aiding the construction of multi-pole filters with improved frequency response.

Title: Means for scale-changing raster scanned  data
Inventor: JUDD IAN D
IPC: H04N1/393
Filed: 1979-12-14
Granted: 1982-04-27
Abstract: ABSTRACT     Data manipulation apparatus is described for converting raster-scanned data received for example from a scanner 2 at a first picture element (pel) resolution to a second lower pel resolution for display for example on a CRT terminal 4. The apparatus includes a scale-changing means 3 which operates on receipt of the image data from the scanner 2 to perform a scale-change operation on the pels, first in the image row direction and then in the image column direction. The row scale-change operation is performed by scale-change projector 5 which functions to replace sub-groups of pels in the input image rows by single pels at its output.  The number of pels in the sub-groups are determined by the degree of compression required to convert to the lower pel resolution.  The significance of the output bits replacing the sub-groups is determined in accordance with predetermined algorithms having regard to the significance of pels in a selected horizontal 'window' of pels which includes the sub-group of pels under consideration.  The image data emerging from projector 5, consolidated in the row direction, is further processed by a second scale-change projector 6 which performs the column scale-changing operation.  The projector 6 operates in a similar fashion to projector 5 except that in this case sub-groups of pels in the image column direction are replaced by single pels at its output. Again, the size of the sub-groups are determined by the degree of compression required to convert to the lower pel resolution.  The significance of the output pels replacing the sub-groups is determined as in the previous step in accordance with predetermined algorithm having regard to the significance of pels in a selected vertical 'window' of pels which includes the sub-group of pels under consideration.

Abstract: ABSTRACT OF THE DISCLOSURE       A slide slidably mounted on an arm secured to an indexing plate has a slider seat for supporting thereon a slider body with its pull tab inserted in a slot defined between the slide and the arm.  The slider pull tab is immovably held in the slot by a ball mounted in the arm and spring-biased into an aperture in the pull tab.  Upon holding of the pull tab, the slide is slightly moved under the resiliency of a spring to lift the slider body until a locking pawl to which the pull tab is connected is withdrawn out of a slider guide channel.  A block mounted on a fixed frame contains a spring-biased presser which, upon lateral alignment with the spring-biased ball, forces the ball into locking engagement with the pull tab in the slot, thereby locking the slider for applica-tion to a pair of slide fastener stringers.

Abstract: Abstract of the Disclosure A clutch device for holding together two articles such as earrings, pins, necklaces, or other small parts.  The clutch comprises a tubblar hous-ing closed at both ends except for a small central opening in each end.  A coil spring is mounted in the housing.  Each end of the spring is turned in-wardly toward the axis of the spring so that a sharpe edge at the end of the spring presents itself to a pin entering the openings.  The sharp edge of the spring grips the pin and holds it against removal. In an alternative construc-tion only one end of the housing is provided with the pin entry, and both ends of the spring are turned inwardly to grip the pin.  In both cases the pressure of the inturned sharp edge is enhanced by the action of the spring coils. The second part of the clutch is thus a pin having a diameter slightly less than the internal diameter of the spring. The pin may, for example, be attached to a piece of jewelry such as an earring. The pin can also be provided with one or more transverse grooves adapted to receive the sharp inturned end of the spring for a more positive grip and lock. The tube and spring can be made ex-tremely small and can be sunk into a part of various items.  With the tube in one part and a pin in the other, two parts can be joined by a frictional grip-ping action of the inturned sharp edge of the spring on the post.
