Abstract: A method of producing a wall or ceiling covering that is dry-stripable from the wall, is flexible and has good opacity, and will fully retain an embossed pattern even when the sheet is soaked with a water based adhesive. A sheet is provided containing 10 to 90% by weight of cellulose pulp fibres and 10 to 90% by weight of discontinuous fibres of two different synthetic thermoplastic polymeric materials. Staple fibres may also be added. The sheet is then heated to a temperature intermediate the temperature of plasticity of the two different thermoplastic materials so that the fibres of one of the thermoplastic materials are rendered plastic and fused together, the other thermoplastic material retaining its fibre structure.

Abstract: Production of a wall or ceiling covering comprising an embossed laminate of a first printable embossable ply, and a second supporting ply. The first ply consists of a paper sheet containing 60-100% by weight of cellulose wood pulp fibers and 0-40% discontinuous fibers of a synthetic thermo-plastic polymeric material. The second ply consists of a sheet of 10-60% cellulosic wood pulp fibers, and 40-90% of thermoplastic fibers (either the same as or different than those in the first ply). A fused three dimensional network is formed by heating the laminate to a temperature at which the thermoplastic fibers are rendered plastic.

Abstract: Members of a particular class of magnetic garnet compositions show characteristics useful for incorporation in magnetic memory devices which depend for their operation on the positioning of single wall domains ("bubbles"). Such compositions, ordinarily in the form of a supported layer, manifest high limiting bubble velocity, thereby making possible high record and access rates. Tetrahedral iron sites in the concerned compositions are occupied by non-magnetic ions in amount such as to result in magnetically balanced iron sub-lattices so that the magnetic moment contribution is made primarily by dodecahedral site ions. Europium is a necessary dodecahedral site occupant. High limiting velocity is attributed to the high value of the gyromagnetic ratio (g value) associated with europium.
