  • Patent number: 4041204
    Abstract: A photosensitive sheet product which enables dry transfer sheets to be made very simply by a process involving photographic exposure, water-washing to remove unexposed parts of the photosensitive material and drying. The photo-sensitive material itself contains the resin or other adhesive present in the letters or other transferable images and the problem of the adhesiveness which would be apparent in the transferred characters or pictorial matter in the product is solved by making the dry transfer sheet with a temporary keycoat which transfers with the characters or pictorial matter and remains as a protective layer on the finished product. Another advantageous feature of the dry transfer sheets described is that they can be formulated so as to be pressure-transferable in the normal way or alternatively can be heated or solvent-treated to exhibit a permanently increased adhesiveness, making broad-area transfer possible using much lower transfer pressures than required in normal use.

  • Patent number: 4039006
    Abstract: A carbon filament wound hollow cylinder comprising at least two carbon filament layers, an inner axial direction-wound layer and an outer circumferential direction-wound layer, characterized in that the modulus of longitudinal elasticity in the circumferential direction of the inner layer is lower than that of the outer layer. Such a cylinder is capable of preventing possible crack formation after shaping owing to its much reduced residual stress exerted due to thermal expansion of a mandrel during shaping and capable of being stably employable as a rotary drum for, ultracentrifugation because compressive stress is exerted effectively to cancel tensile stress caused by thermal stress for causing interlaminer delamination during high speed rotation.

  • Patent number: 4035547
    Abstract: A technique for bonding plastic materials includes placement of minute particles at the interface, either between the interface surfaces or within one or both of the interface materials. A particle-moving field, such as an alternating magnetic field where magnetic particles are employed, is created across the interface to directly and correspondingly impress the alternating magnetic field on the magnetic particles while the interface is in a generally movable or yielding state. The alternating magnetic field continuously moves the particles and by proper orientation causes them to oscillate, rotate or otherwise move within the fluid interface material to move and intermix the plastic material and thereby produce an improved interface bond between the materials. The magnetic particles may be selected to also respond to a radio-frequency magnetic field to rapidly generate heat and thus simultaneously create the fluid material at the interface with the material agitation.

  • Patent number: 4035539
    Abstract: A panel of spaced, parallel, translucent, outer sheets of set plastic material with an inner sheet of corrugated sheet plastic disposed therebetween with the crests of the corrugations at the opposite faces of the corrugated sheet being engaged with, and secured in fixed relation to, adjacent outer sheets, respectively. Each corrugation has alternate show areas and shade areas. The show areas are coated with material which reflects light or impedes the passage of light therethrough. The shade areas are generally uncoated so that, relative to the show areas, their reflectivity is less and their light transmission is greater. The corrugations are so related to the outer sheets that, in the panel cross section, they define with the outer sheets right angle triangles with one side of each corrugation at a right angle to both outer sheets. The resultant panel is thus a truss structure, having high strength, desirable controlled light transmitting characteristics, and high heat insulating properties.
