Abstract: DISPENSING PUMP HAVING      COLLAR-TO-BODY ANTI-ROTATION INTERLOCK     Abstract of the Invention Serrations on the upper end of the pump body are  disposed  for  interlocking  engagement  with depending portions of the pump collar so that when the  plunger  is  rotated  in  a  counterclockwise direction to unlock the same from the collar in preparation for reciprocal operation, the collar is held securely by the body against rotation to assure unlocking.  The serrations take the form of a plurality of equally circumferentially spaced ramps which are inclined upwardly in the direction of locking rotation of the plunger to thereby permit the collar to yieldably override the serra-tions when the locked plunger and collar are rotated as a unit in the locking direction rela-tive to the body to orient a spout of the plunger in a desired location for factory packaging effi-ciency.

Abstract: METHOD AND SYSTEM FOR IMPROVED RECONSTRUCTION OF VIDEO IMAGES IN LINE SEQUENTIAL CHROMA FORMAT                   ABSTRACT A method and system for reconstruction of chroma component segments in a line sequential chroma format television system.  Filtering of a received line sequential chroma signal is employed to reconstruct missing chroma components and to attenuate phantom fre-quency components greater than one half the spatial sampling rate.  Digital and analog filters are dis-closed for implementation of such post filtering.  The luminance component of the line sequential signal is delayed at the transmitter to synchronize the recon-structed chroma segment with its corresponding lumi-nance segment with the use of minimal hardware at the receiver.  Horizontal offset chroma sampling is used along with such post filtering to decrease transmission bandwidth requirements without sacrificing horizontal resolution at the receiver.

Abstract: PROTECTIVE COATINGS FOR ASPHALTIC CONCRETE SURFACES AND METHODS FOR FORMING THE SAME         Asphaltic concrete surfaces are protected from unde-sirable changes by applying a composition comprising a dior-ganopolysiloxane containing rod-shaped styrene-n-butyl acrylate copolymers which are obtained from the free-radical copolymeri-zation of said monomers in the presence of the diorganopoly-siloxane onto an asphaltic concrete surface and thereafter crosslinking the diorganopolysiloxane composition to form an elastomeric coating thereon.  The asphaltic concrete surface may be coated with a primer prior to the application of the cross-linkable diorganopolysiloxane composition in order to improve the adhesion of the resultant crosslinked elastomer containing the rod-shaped copolymers.  These asphaltic concrete coatings are especially useful in, for example, hydraulic engineering.

Abstract: ABSTRACT:            A decoding device for code words which are pro-tected against the occurrence of several symbol errors per code word by means of a Reed-Solomon code is provided with a word buffer which comprises a space for the storage of an erasure indication per symbol received.  For correction of the code word, first the syndrome symbols are formed by multiplication by the parity check matrix.  The sum of twice the number of error symbols and once the number of erasure symbols may not be larger than the number of syn-drome symbols.  First the syndrome symbols are modified so that the syndrome symbols which could possibly relate to error symbols (non-erasure symbols) are no longer influ-enced by the erasure symbols.  The key equation and error locator equation for the non-influenced syndrome symbols can then be separately solved, so that the locations of error symbols can be found.  The latter syndrome symbols are then modified, when necessary, for calculated error locations, while the error values or erasure values are determined from a set of mutually independent syndrome symbols whose number equals the sum of error symbols and erasure symbols.  There is provided an arithmetic unit for the Galois-field which, for the sake of simplicity, per-forms the calculations on the exponents of the symbols which are written as powers of the basic symbol of the Galois-field.
