  • Publication number: 20220313495
    Abstract: Dressing or bandage for protecting a wound accidentally incurred, surgical incision deliberately made in the skin, epidermal delivery of medication, or musculotherapy of a human being or animal, said bandage/dressing having the primary characteristic of being significantly atraumatic upon removal of same by virtue of a novel stringlike member that is intentionally incorporated into or debossed into the construction of said parent bandage/dressing in a multi-spiral geometry, said stringlike member firstly being pulled gently and progressively in multiple turns around the wound site or epidermal treatment area to in effect significantly reduce the area of remaining/undisturbed adhesive between the bandage/dressing and patient's skin before the bandage/dressing is peeled away from the skin in conventional manner and thus affording the patient a significantly less traumatic experience.

  • Patent number: 7165461
    Abstract: A pressure gauge comprising a stem having an inlet at which pressure is sensed. A Bourdon tube is coupled to the stem and is displaceable in response to pressure changes at the inlet. A movement comprising a movement plate conducts displacement of the Bourdon tube to a pointer shaft. A circuit board comprising an inductor is fixed relative to the stem. The movement plate comprises an integral flag connecting the movement to the Bourdon tube and an integral inductive target operatively positioned relative to the inductor.

  • Patent number: 3952598
    Abstract: A pressure gauge of small size and type suitable for fire extinguisher use. Comprising the gauge is a dial plate secured in keyed registration onto the front face of the casing. A tubular stem extending laterally from the inside face of the viewing crystal is axially slotted to embrace a radial portion of a wound Bourdon tube supporting a pointer opposite the dial plate. Rotating the crystal prior to securing it to the casing enables the tube slot to zero position the pointer at the zero graduation on the dial plate. When secured to the casing the distal end of the crystal stem compresses an O-ring washer for effecting an internal pressure seal between the casing and Bourdon tube thereat.
