Abstract: An improved flying pet toy is formed of a suitable matrix material and an attractant for enhanced retrievability and wear resistance, including a circular crown portion having a center, an intermediate circular surface area surrounding the center, a circumferential portion surrounding the circular area. A projecting ridge extending outward from the top surface of the circular crown may also be included. Various other embodiments of the improved pet toy are also disclosed.

Abstract: A method of binding a book which includes gathering and binding a plurality of signature pages into a book block, connecting first and second upper end pages by a buckram hinge strip, connecting third and fourth lower end pages by a buckram hinge strip, sewing the hinge strips, top and bottom end pages and the inner portion of the book block together and then gluing a cover to the exterior of the top and bottom end pages, hinge strips and spine of the book block.

Abstract: This invention relates to an improved chewable object or toy formed from a polyurethane resin having an aqueous based flavor or odor incorporated therein after the object or toy has been formed. The object or toy is particularly suitable for domestic animals such as dogs and cats.

Abstract: A chewing toy for dogs and a process for its preparation, wherein a nylon piece, preferably having the shape of a bone, has an impregnated layer of caramelized sugar adjacent but below its surface to impart a dark brown color and a flavor to the near-surface region of the toy. The chewing toy is prepared by placing a piece of water-absorbent nylon into an aqueous solution of caramelized sugar at a temperature of about 250.degree. C. and an applied pressure of about 30 psi for a period of at least about 8 hours, so that the aqueous solution penetrates into the surface of the piece to impart the dark brown color to the near-surface region of the piece. The coloring and sweet taste provide an initial appeal to the animal, increasing its initial acceptance of the toy. The heat treatment also anneals the as-formed nylon to impart greater strength, reduce brittleness, and improve its resistance to shattering.

Abstract: A method for bookbinding on a continuously-moving, constant-speed conveyer belt operation with the case or back-strip being centrally located on the axis of motion. As the case is formed between opposing rotary irons, glue or paste is then applied to the upper insides of both sides of the case. A book block is next dropped on one side of the case, the book block is aligned to register with the case; and the other side of the case is folded over to fasten to the upper side of the book block to form the book and prepare it for pressing and crimping of the building-in operation, without any interruption of the motion of the book along the conveyer system.

Abstract: A method for binding a book wherein the backbone of printed and folded signatures receives a heat activated glue. A short reinforcing cover whose inner surface is also covered with a heat activated glue is applied to the backbone. The outer portions of the short cover are then bonded to the outer pages of the signatures, under sufficient heat and pressure to form a strong bond. A hard cover of suitable size and shape is then glued to the outside of the short cover and the signatures.

Abstract: A process is provided for binding a plurality of papers arranged together in signatures using an adhesive without requiring the spines of the signatures to be trimmed in order to allow adhesive applied from a single source to contact all of the papers to be bound. A linear array of apertures is cut into each of a plurality of papers. Each paper is folded back on itself to form a signature having two layers of paper with the apertures in each layer at least partially aligned. The signatures are positioned side by side and adhesive is applied concurrently to the spines of all of the signatures, thereby introducing adhesive into the apertures and bonding all of the layers of paper to each other. A backing is contacted with the spines of the signatures to form a cover, thereby providing a bound publication.

Abstract: There is disclosed a method for binding books utilizing a plurality of signatures which are glued together along a spine. First and second additional signatures or covers are thereafter glued to such spine. The outermost of said special signatures is glued to the interior surface of a hard cover.
