Abstract: A foam earplug for reception at least partially within the ear canal and including a body portion formed of resilient foam plastic material having a multiple open cell structure and having a size and shape for at least partial reception within the ear canal. A transdermal material having a particular beneficial action, and with an outer layer of the foam earplug infused with the transdermal material so that the benefits of the transdermal material is in transdermal contact with the ear canal. One example is a humectant material and, specifically, a moisturizer/lubricating material, for providing an increase to the lubrication and moisturizing in the car canal. A second example is where the beneficial action is provided by systemic distribution such as a sleep aid, i.e., Melatonin, so that when the earplugs are worn during sleep, the earplugs will provide a sleep aid to the wearer.

Abstract: An apparatus and a method of making a corded earplug, including a flexible cord material having a particular cross-section. An earplug having a nose portion for insertion into the ear and a handle portion extending from the nose portion and lying outside of the ear when the nose portion is inserted into the ear. The handle portion including at least two openings physically displaced from each other. At least one of the openings extends within the handle portion and with at least one of the openings having a cross-section different than the cross-section of the cord material. An end portion of the flexible cord material is inserted into the at least one opening extending within the handle portion.

Abstract: An earplug dispenser for manual operation by a user includes a bottle member to receive a plurality of earplugs. A dispensing mechanism is located at an open end of the bottle member so that when the bottle member is turned upside down, the dispensing mechanism projects downward and the earplugs fall by gravity to the dispensing mechanism. The dispensing mechanism includes an impeller member having a plurality of impeller openings to have individual earplugs located within the impeller openings by gravity and additionally includes a knob member projecting downward from the impeller and including a ratchet mechanism so that the rotation of the knob provides for rotation of the impeller and any individual earplugs captured in the impeller openings in only one direction.

Abstract: A wireline conveyable device for a fluid operable borehole tubing assembly comprising a tubular body having a first end intended to form the upper end when in the borehole and a second open end intended to form the lower end. The tubular body includes at least one aperture in a wall thereof to facilitate passage of fluid through the tubular body. Electrically actuable outwardly moving anchoring means are attached to the tubular body for positively locating the tubular member at a predetermined position within the borehole tubing, in use. An electrically actuable sealing means attached to the tubular body and arranged, in use, for selectively sealing the space between the borehole tubing and the tubular body to divert fluid through the tubular body to bypass the sealing means for driving fluid actuable means located adjacent said second lower end of the tubular body.
