Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a doppler navigational radar antenna with automatic land-sea correction utilizing the production of two somewhat differently inclined mutually overlapping labe groups each having four lobes.  The antenna comprises a plane radiation array group having individual radiators disposed in parallel rows.  Each radiator having two ends which have respective feed points.  Each radiator is either actually fed or fed by way of radiation at the feed points by a first pair of feed lines extending transverse to the rows of radiators and coupled thereto at the respective feed points at one end thereof and a second pair of feed lines extending transverse to the rows of radiators and coupled thereto at respective feed points at the other end thereof.  One feed line of each pair has a different phase delay than the other feed line of the same pair. The different phase delay is set correspondingly small so as to obtain the overlapping of the lobe groups.

Abstract: A B S T R A C T           The invention relates to polymeric laminates for packaging.  According to the invention, such laminates contain an oxygen barrier layer which is composed of a hydrolysed olefin/vinyl ester copolymer, preferably a hydrolysed ethylene/vinyl acetate copolymer.  Other layers in the laminate protect the oxygen barrier layer from moisture and provide a heat-sealable surface layer. The laminates withstand the temperatures of 80-125°C employed in pasteurisation and sterilisation procedures, and are therefor of value in the preparation of pasteurised and sterilised packages of oxygen-sensitive foodstuffs.

Abstract: ABSTRACT OF THE DISCLOSURE    A cassette for holding a stack of cards, paper or the like sheets to protect the stack and to enable removal of one more sheets or of the entire stack.  The cassette is of an extremely simple and thus inexpensive, unitary, flat struc-ture having a bottom wall, peripheral walls for protecting the edges of structural sheets and a spring tongue on top, the spring tongue being unitary with the rest of the structure.          The spring resiliently urges the stack against the bottom wall.          The bottom wall has an opening for pressing the stack within the cassette against the spring when removing one or several of the sheets.  The advance over prior art is not only in an inexpensive structure but also in convenient handling of the sheets, whether in re-filling or in removal of the entire stack or of only few sheets, as the spring tongue is maintained in contact with the stack during the removal of the sheets thus preventing accidental spilling of the cards or the like.

Abstract: APPARATUS AND METHOD FOR PRODUCING STEREO-REGULAR POLYMERS     ABSTRACT OF THE DISCLOSURE     Stereo-regular polymers are produced by forming a moving stream of gaseous monomer having an electric dipole moment, irradiating the monomer with monochromatic light of a wavelength suitable for activating it, and orientating the activated monomer in an electric field.          The activated, orientated monomer then polymerizes to form a stereo-regular polymer.         Alternatively, a monomer of the general formula   can be used, where at least one of the R groups, the resonating R group, forms an electric dipole moment with the remainder of the monomer.  The monomer is then irradiated with a monochromatic light beam having a fre-quency which resonates with a harmonic frequency resulting from the bond between the resonating R group and the remainder of the monomer.  Activation of that particular bond on that particular type of monomer results in a stereo-regular polymer.         For best results, however, the two methods are combined.
