Abstract: Surgical sutures are protected from damage in shipment and handling by providing holders having foamed plastic shapes that are adapted to receive the point and cutting surfaces of a needle in an edge portion of the foamed plastic shape and retain the suture in a manner so that the suture can be easily removed from the holder without the need for undue manipulation of the holder. The holders may also serve as a support to facilitate the manipulation of the needle or suture by operating room personnel, to organize and provide access to selected lengths of surgical thread, and to provide an identifiable repository for used needles. The foamed plastic protective handling devices of this invention are particularly suitable for use in cooperative relationship with selected packaging materials to permit the storage of needles and sutures under sterile conditions.

Abstract: Apparatus and method for forming hollow articles from plasticized materials are disclosed. A preform is partially formed under substantially no pressure on a preform core by introducing the core into a void-free charge of plasticized material that is placed in a preform cavity from a source of the plasticized material. After the preform core and preform cavity have moved together to define a preform mold space, the charge of plasticized material is subjected to a pressure forming step to form a completely packed preform on the core. The preform is then blow-molded in a blow cavity by introducing blowing gas into the preform through the preform core. Neck mold structure that strips and releases the formed article from the core is also disclosed.

Abstract: Apparatus and method for the continuous manufacture of structural shapes are disclosed. Mineral fiber material in the form of continuous strands, webs, or mats, impregnated with a heat-hardenable resin, is passed through a dielectric heater. The material is shaped as it passes through metallic dies that are disposed within the dielectric heater. The electric field between the electrodes of the heater is reduced or shunted at the location of the dies. The heater is arranged so that the maximum electrical field occurs adjacent the entrance to the heater.

Abstract: Apparatus and a method for forming a uniform film of plastic material, having good optical characteristics, on a substrate are disclosed. The plastic material is supplied to and maintained under pressure in a distribution channel and is fed from the distribution channel through a narrow slot to the substrate. A forming member subsequently forms the plastic material into a uniform film on the substrate. The level of the plastic material in front of the forming member is limited to a range of values based upon the thickness of the film being formed.

Abstract: A fireplace is disclosed in which the ash dump is utilized to supply combustion air to the fireplace so that air will not be drawn by the fireplace from the room in which the fireplace is located. This is accomplished by locating an air diffuser over the ash dump in combination with an ash pit clean-out door that can be adjusted to control the flow of air through the ash dump and into the fireplace. The ash pit clean-out door may be located either on an outside wall to draw in outside air or it may be located in a non-living area of a home, such as the basement.

Abstract: Method and apparatus for the continuous production of transparent films, sheets, or plates of high optical quality are disclosed. Material in liquid form flows onto a substrate comprising a plurality of discrete, distortion-free panels, disposed in end-to-end abutting relationship and moved continuously beneath a flow head from which the material flows onto the panels. The panels move on a conveyor system that progressively slows the speed of the plates, so that leading and trailing edges of successive panels abut to form a continuous surface as the panels pass beneath the flow head. Yieldable, elastic sealing strips are placed between the panels to form a part of the continuous surface and to cushion jolts as succeeding panels are moved from the upstream end of the conveyor and come into contact with the continuous line of panels passing beneath the flow head.

Abstract: A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.
