  • Method of making filter cell having sealed periphery
    Patent number: 4347208
    Abstract: A method is provided for making a filter cell comprised of two cellulosic fiber containing filter media having a sealed periphery. The method comprises compressing the peripheries of each filter media, to form a flange. The media are then aligned to provide intimate face-to-face contact between the flanges. A spacer means is provided between the media to cause each to dish outwardly from the other media. The two media and spacer means are then placed into a mold surrounding the flanges. The mold has a means for providing a recompression force to the inner portions of the flanges. A thermoplastic polymer is then injected into the mold to form a seal around the flanges. The recompression force is sufficient to maintain the flanges in intimate face-to-face contact with each other and to prevent seepage of the polymer between the flanges when the polymer is injected into the mold.

Each leg has two outwardly and upwardly extending arms at each side of the leg. The free ends of the first arms at each end of the aperture are resilient and capture a tab on a metal housing of the slide switch thereby releasably holding the switch to the adapter. The free ends of the second arms at each end of the aperture face the periphery of the aperture and snap under the edge of the aperture to hold the plastic adapter in the frame.

  • Ear lobe clip with heart beat sensor
    Patent number: 4334544
    Abstract: A pair of generally parallel spaced plastic arms are pivoted to each other at their central portions by interleaved pairs of tabs having a pivot pin extending therethrough.

The one pair of opposite ends have a pair of hollow bosses formed thereon, with heart beat sensors positioned in each boss. Electric wires connected to the sensors extend therefrom along the arms through channels formed in the arms. The pivot pin has heads formed at its opposite ends. Apertures are formed in these heads and an elongated strip of plastic material has its opposite ends positioned in the apertures so that the remainder of the strip of material comprises an open loop for hanging the arms off the ear of the lobe to which the arms are clipped.
