Abstract: There is disclosed a novel electrode assembly or package for two or more electrode devices, and also a novel method of fabricating not only the overall assembly, but also the devices in conjunction therewith. The electrode assembly as contemplated by the disclosure includes a carrier member in generally strip form having one or more openings therein, the number of said openings depending upon and being equal to one-half of the number of electrode devices to be employed in said assembly. A medical electrode device is secured in overlying relation to each opening, on opposite sides of the carrier member, with the gel pads of each said electrode device being disposed within the periphery of the opening and in face-to-face contact with the pad of the opposed electrode device. The electrode devices may be pre-gelled, if desired. It is contemplated that the assembly may then be packaged in a suitable container, such as a plastic or foil envelope.

Abstract: An easy and quick method of placing a stiffening heading to draperies without the use of a sewing machine and the help of pins or staples. The invention discloses the use of any drapery stiffening or heading with at least one and preferably two fine lines of adhesive or glue having a low melting point positioned on the heading parallel to the longitudinal side edge thereof. The drapery fabric or crinoline is joined to one line by heat sealing and then the stiffening is turned inside of the upper end of the fabric and the second line is heat sealed whereby the drapery stiffening is secured in a straight and accurate manner to the top of the fabric whereby the pleats can subsequently be sewn therein.

Abstract: A sheet material is initially formed into a flat and quadrilateral bag, the four sides of which are sealed. Each of the front and back sheets of the flat bag is pinched up and folded in two parts at each corner region along a line running through a point placed at a selected distance from the corner such that two imaginary and symmetrical lines drawn on the inner surface of the sheet meeting at this point and terminating respectively at the two adjacent sides of the corner region are overlapped each other, and then a joint is formed in the folded region of the sheet along the overlapped lines.

Abstract: A method for automatically producing bib aprons from a continuous web of nonwoven fibrous material. The web is unwound from a supply roll, and beads of adhesive are applied adjacent its longitudinal edges as it is advanced along a feed path. The edges are then folded over the adhesive to provide longitudinal reinforcements, and the web is cut in a direction transverse to its direction of movement to form rectangular blanks. As the blanks continue along the feed path, additional beads of adhesive are applied to each blank in spaced areas adjacent a pair of opposed corners. To produce the neck loop and tie elements for the apron, a single narrow strip of nonwoven fibrous material is positioned over the blank in a direction transverse to its direction of movement, and the center of this strip is pulled in the direction of movement such that the strip forms both the neck loop and the tie elements. The opposed corners of the blank are folded over the adhesive areas to hold the strip in place.

Abstract: An air filter of the type having a porous filter medium body layer supported in a complementary unitary frame has a perforated panel supportingly engaging one face of the layer with folded up narrow panels along the edges of the layer, narrow retainer panels overlying the margins of the opposite face of the layer from the perforated panel, and each of the retainer panels being provided with spaced extensions which overlap adjacent the corners of the layer and are secured together as by means of adhesive, there also being anchoring adhesive securing two of the retainer panels to the filter layer. The overlapping extensions are perforated.An efficient method of making the air filter is provided.

Abstract: A structure suitable for in vivo implantation as a tension member to substitute for tension members such as ligaments and tendons. The structure includes an elongate member which is a biocompatible film, a biocompatible fabric which has a weave having substantially no permanent yield in one direction after said film is formed thereon and a biocompatible porous material which promotes the ingrowth of living tissue and such material is either bonded to the exterior of the elongate member or is contained within and exposed to the exterior. Also disclosed is a structure having a fabric with a film formed thereon and porous ingrowth material bonded to one or both sides threof to form a patch for in vivo implantation. The film used on the patch may be porous or solid depending on whether the patch is to be permeable to body fluids.

Abstract: A container is provided formed from a blank made of a laminate which includes nonbrowning paperboard and at least an inner layer of substantially amorphous polyethylene terephthalate bonded to the paperboard by its own substance. A method of making this laminate is provided including the steps of heating an uncoated surface or both surfaces of the paperboard to a temperature of at least about 285.degree.F. and extruding the polyethylene terephthalate layer onto this surface or these surfaces. A method of cooking is provided including the steps of forming a container from the blank, placing food in the container and cooking the food at a temperature of up to about 400.degree.F.
