Abstract: Disclosed is a novel paper sheet adapted for the electrostatographic reproduction of images on both sides thereof. The paper bears a surface sizing material having dispersed therein a plurality of microcapsules comprising water or a hydrated salt encased in an impervious capsule wall of a solid material. As the paper is subjected to the electrostatographic fusing operation, water is released from the microcapsules to replenish that lost due to the heat of fusing. In this manner, the paper can be imaged on its other side without encountering the problems associated with dehydration of the paper.

Abstract: This invention relates to an improved multifilament bundle which is made of thermoplastic polymer and usable without twisting and represents a linen-like touch. The multifilament bundle comprises a plurality of monofilaments of the same kind of thermoplastic polymer, said monofilaments being bonded thermally and partially together with neighboring at separated places thereof, each of said bonded places extending short distance along and in the longitudinal direction of monofilament, so as to make the constituent monofilaments coherent with each other into a non-torqued, non-bulky continuous yarn. This yarn can be fabricated, without sizing, into a textile fabric. This yarn can be used in various fields requiring untwisted yarns including sewing machine yarn. This yarn can be manufactured by passing a multifilament as spun at underfeed condition through a passage zone where heated fluid flows are brought into collision with each other.

Abstract: A unitary, heat and pressure consolidated laminate comprising at least one paper sheet, a decorative sheet and a coating on said decorative sheet, said paper sheet and said decorative sheet being impregnated with an acrylic resin-melamine/formaldehyde resin composition and said coating comprising an acrylic resin-alkoxymethylated melamine composition.

Abstract: A self-tracking recording tape is disclosed. The invention is primarily directed to thin base magnetic recording tape. However, the concepts of this invention are equally applicable to other recording tapes or film. Instead of a flat base tape, the tape of this invention is corrugated to form a plurality of V-shaped tracks across the width of the tape. The tape reels, the transport mechanisms, and the playback-reproduce heads utilized with the tape of this invention are all designed to accommodate the V-shaped grooves in the tape. In this manner, the tape becomes essentially self-tracking. That is, no auxiliary or additional guide means such as the edge guides normally used with magnetic tape recorders, are required to properly guide the tape across the head. In addition to the self-tracking feature, tapes designed in accordance with this invention can accommodate a large number of tracks across a given width of tape.

Abstract: A pad is provided made from resilient sheet material and of single sheet thickness or cross section. The pad is, in general, in the overall form of a frustum having a socket for receiving an article to space it from its outer box, the pad being positioned angularly at the box corner. Further, the pad is flexibly deformable to cushion the article on impact. In use in a box, four pads are placed in the bottom corners of the box; the article is then guidedly slid into seated engagement with the sockets of the pads; and then, the top four pads are placed on the top of the article, after which the top of the box is closed. The pads are stackable in nested condition, thereby facilitating storage and shipment to the point of use.

Abstract: A unitary, heat and pressure consolidated laminate comprising at least one paper sheet, a decorative sheet and a coating on said decorative sheet, said paper sheet and said decorative sheet being impregnated with an acrylic resin-melamine/formaldehyde resin composition and said coating comprising an acrylic resin-alkoxymethylated melamine composition containing pyrophyllite, andalusite or mixtures thereof.

Abstract: A projectile energy absorbing protective barrier comprising a blanket formed of multiple layers of woven cloth and a rigid supporting layer is disclosed. Each cloth layer comprises a plurality of tapes, each tape formed of high tensile strength, continuous filaments having a low modulus of elasticity. The cloth layers are each woven in a manner such that relative sliding movement between the tapes is permitted. The rigid backing layer supports the multiple cloth layers in a corrugated configuration such that the longitudinal axes defined by the corrugation nodes lie at an angle relative to the direction of the weave pattern. The corrugations, and the weave pattern, allow the cloth layers to instantly move without resistance upon impact by a projectile, in the direction of projectile travel. Subsequent to impact and achieving the speed of the projectile, the filaments wrap partially around the projectile and contain it by reacting in tension.

Abstract: There is provided a laminate of at lest two thermoplastic films which has a plurality of embossed parallel ribs running in at least one direction, said films being blocked together at spaced apart spots along each rib. Such laminate is prepared by passing at least two thermoplastic films in a superimposed and contacting engagement with one another through the nip of a pair of rollers. One roller is provided with a plurality of parallel raised ribs running in one direction and the other roller is provided with a plurality of parallel raised ribs which run in a direction angled to the direction of the ribs on the first roller. At the locations where the ribs on each roller cross at the nip, the films in the laminate are blocked together but otherwise remain unattached. Such laminates have exceptionally high tear strength and added stiffness and are adapted for various uses, including heavy duty bags and grocery sacks.

Abstract: The product is a laminar composite of two or more adhesively bonded layers of sheet material, one of which has a corrugated surface contour at the interface between the layers. The layers are bonded together at the ridges of the corrugated surface of the one layer, and the bond on each ridge consists essentially of a series of relatively localized spots of a plastically deposited but adhesively set adhesive material. The spots are located at intervals spaced apart from one another lengthwise of the ridge, and are characterized with oblate cross sections in planes normal to the interface between the layers, resulting from the fact that the spots undergo compression in the plastic state thereof during the process. The bonding operation is accomplished by causing relative motion between the corrugated web and a series of spaced parallel lines of adhesive material which are disposed crosswise of the ridges of the web and contacted with the ridges so as to deposit the spots thereon.
