Abstract: ABSTRACT     A method of manufacturing an edge element, which is a laminate and comprises a porous core layer (9) and a hard surface layer (8).  A non-stretchable layer (6) is placed on a foldable mold (1,2,3,4,5) on a support.  A hardenable layer (8) is sprayed on the non-stretchable layer (6).  The porous core layer (9) is placed on the hardenable layer (8) and the mold with the non-stretchable and the hardenable layer are folded around the core layer.  The non-stretchable layer contributes to making the hardenable layer come very close to the surface and the edges of the core layer.  Crack formation, curved rather than sharp edges and wrinkle formation are prevented in the finished laminate.

Abstract: ABSTRACT OF THE DISCLOSURE   A vibration damped rotary disk is provided and includes a pair of circular disk panels disposed in side-by-side superposed relation.  The panels include shallow concentric and opposing annular recesses formed therein of a radial extent greater than one-half the radial extent of the panels and spaced inwardly of the outer marginal portions of the panels. A filler of mechanical vibration dampening and absorbing material is disposed in and fills the recesses and the outer marginal portions of the disk panels disposed outwardly of the recesses are secured together.  Preferably, circumferentially spaced rivets are utilized to secure the outer marginal portions of the disk panels together and those opposing surfaces of the disk panels disposed radially outwardly and radially inwardly of tile recesses have a thin layer of Teflon interposed therebetween, the disk panels being constructed of metals.  The opposing inner surfaces of the recesses may be finely or coarsely roughened, to provide intimate stabilization of the filler material relative to the disk panels.  Such roughening may be in the form of fine concentric circular grooves formed in the recess inner surfaces or by more coarse texturing of the recess inner surfaces.

Abstract: Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure. Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings. The loading apparatus is pivotally mounted. Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded. The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: Abstract of the Disclosure A substrate for an alkaline battery separator is made of a light weight, porous, heat bonded, synthetic organic sheet material having a basis weight of less than about 35 gsm and a thickness of less than about 200 microns.  The major fibrous component is synthetic pulp comprising thermo-plastic polyolefin fibers having a prefused microfibrillar structure similar to wood pulp.  The minor fibrous component is a high tenacity polyamide fiber having a fiber length greater than about 6 mm.  The heat bonding by partial fusion of the microfibrillar polyolefin is sufficient to impart to the sheet material a wet tensile strength of at least 400 g/in. width while permitting retention of air permeability of about 100 liters per minute and more.  The substrate ex-hibits excellent receptivity to impregnation by pore-form-ing battery separator coatings and is particularly well suited for use in nickel-zinc batteries.

Abstract: HEAT BULKABLE POLYESTER YARN     ABSTRACT OF THE INVENTION     The present invention relates to a process and product for directly producing a latent heat-bulkable yarn from the same polymer composition in the same spinning process.  The self-crimping yarn is produced from polyethylene terephthalate compositions which are melt spun at high speeds to form a plurality of spin oriented filaments. The filaments are divided in the spinning column into at least two groups and the two groups of filaments are subjected to different heat conditions, recombined, and taken up as a fully drawn yarn.  The high spinning speed and differential heat treat-ment are selected to produce highly spin oriented yarn of relatively high spun birefringence with the conditions of spinning speed and heat treatment being controlled to produce a desired shrinkage differential between the two groups of filaments of up to 60 per-cent.  The yarn is self-crimped by subsequent heat treatment to effect shrinkage, preferably after being formed into fabric, such as occurs in the hot dyeing and/or scouring of the fabric.

Abstract: ABSTRACT       Macromolecular reconstituted collagen is prepared by treat-ing natural insoluble collagen with an aqueous solution comprised of an alkali sulfate salt and an alkali metal hydroxide for at least 48 hours to saponify fats suspended within the natural insoluble collagen.  The fat free collagen is then treated with an aqueous solution comprised of an alkalie metal sulfate for at least four hours to stabilize the interfibular bonds between individual polypeptide chains.  The collagen is then dis-solved in an aqueous acid solution and frozen at a rate of -20°C/hour. The frozen collagen is vacuum dried at 10-3 to 10-5 torr for at least 16 hours to produce a biologically active collagen article.  Various bio-logically active materials may be added to the aqueous acid solution prior to freezing.  The collagen product may then be implanted into an animal or the like and the medication slowly released.  The article can remain within the biological system and it will slowly dissolve due to enzymatic digestion and through other biological processes.
