Abstract: A support assembly for facilitating the hanging or display of a picture, preferably provided in the form of an unassembled kit, includes a plurality of separate relatively rigid elongate channel-like grid members preferably identical in construction and a plurality of attachment members preferably in the form of double-sided, acid free adhesive strips for attaching the grid members to the back of a picture. Each grid member has a plurality of slots defined at uniformly spaced locations therealong for facilitating the breaking off of an end portion thereof to provide the grid member matched in length to a dimension, such as the length of width, of the picture. A plurality of spaced apart rupturable webs are provided which span each slot and integrally interconnect portions of the grid member that define opposite sides of each slot so as to reinforce the grid members at the locations of the slots.

Abstract: A method of forming fibers from a flowable thermoplastic forming material wherein the fiber forming material is fed onto an outer surface of a spinning element which tapers inwardly to a terminal point and sweeping the fiber forming material with a flow of heated fluid along the surface of the spinning element and spinning the fiber forming material from the terminal point into congealed fibers under the continued influence of the sweeping fluid, cooling the uncongealed fibers to form a uniform suspension in the sweeping fluid and collecting the congealed fibers.

Abstract: A precision thermoplastic filament winding process for forming into pipe or similar articles by winding strands comprised of semi-hardened thermoplastic material on a rotating mandrel to form a layer thereon.Single or multiple component, unreinforced and/or continuously reinforced filament wound cylindrical products are continuously produced by winding, at least an inner layer of thermoplastic material upon a rotating cooling mandrel which reciprocates axially in timed relation with moving guiding means and a rotary stripping means.Timing sequence provides a dwell relationship between the cooling mandrel and the hot semi-molten applied material so that at least the inner surface of the freshly applied material is rendered non-sticking and strong enough to enable it to be moved along the surface of the mandrel an incremental distance determined by the planned sequence and pattern required to give the desired specific properties.
