  • Patent number: 5752280
    Abstract: An eyeshield removably attached to a headgear. The eyeshield manually rotates from a normal viewing position to an out of viewing position above the forehead by means of two sets of pivotal arms attached to a unique bistable tensioning pivotal mechanism. This mechanism applies tension to keep the eyeshield held firmly in place in the normal viewing position, and when the eyeshield is manually lifted toward the out of viewing position above the forehead, tension is applied in the reverse direction to keep the eyeshield held firmly in the out of viewing position. The position of the eyeshield may also be adjusted with respect to the face of the user.

  • Patent number: 5476664
    Abstract: A method of treating a patient having one or more warts includes the steps of: applying to the wart an amount of a composition consisting essentially of an anthralin active ingredient and a pharmaceutical carrier; covering the wart and skin areas peripheral to the wart with an adhesive tape, such that the adhesive tape adheres to peripheral skin areas, whereby the adhesive tape provides an occluding environment for the wart treated with the composition. The occluding environment is maintained for a desired period of time, and the adhesive tape is removed. For a number of times as desired, a fresh amount of anthralin-containing composition is applied, and a fresh piece of adhesive tape is applied to recreate the occluding environment.

  • Patent number: 5280176
    Abstract: A system is disclosed for performing x-ray photoelectron emission analysis which uses a collimated x-ray beam directed to an optically polished sample at a small grazing angle of incidence, a fixed sample/electron spectrometer geometry, and an x-ray detector for detecting x-rays reflected off of the sample. With the system, an enhancement of the x-ray field at layer interfaces in a multilayer sample can take place. The system permits depth profiling of an over layer on a substrate, such as a metal or metal oxide on a metal substrate. The enhancement permits absolute calibration of depth-dependence. The system reduces lineshape distortions due to inelastic electron scattering of exiting photoelectrons and eliminates energy distortions due to changes in the sample position relative to the focal point of the electron spectrometer.

  • Patent number: 4960018
    Abstract: A method for recording and playing back telephone conversations is provided. In the method, a unitary microphone/speaker is positioned near the listener's ear so that the unitary microphone/speaker will be in the sound chamber defined by the air space between the telephone earpiece and the ear of the listener when the earpiece is pressed against the listener's ear. The unitary microphone/speaker is connected to an audio recorder/player, and the conversation is recorded. The telephone earpiece is removed from the listener's ear, and the recorded telephone conversation is played back by the recorder/player. The telephone conversation may be played back through the unitary microphone/speaker directly into the listener's ear. In accordance with another aspect of the invention, a method is provided for enabling the conversion of an ear mounted speaker into a unitary microphone/speaker for use in the sound chamber between the earpiece and the listener's ear.

  • Patent number: 4862509
    Abstract: A portable system for recording telephone conversations from a telephone and also for recording face-to-face conversations includes a portable, battery-powered audible sound recorder carried by the user, a microphone connected to the recorder, and a microphone support which is supported by the ear of the user for retaining the microphone between the telephone earpiece and the inner portion of the auditory meatus of the user. By locating the microphone near the auditory meatus or in the outer portion of the auditory meatus of the user, sounds of the face-to-face conversation and sounds of the telephone conversation from the earpiece are recorded on the recorder. With the recording system of the invention, there is no physical contact between the microphone and the telephone earpiece. A microphone holder is also disclosed for retaining a small microphone near or in the auditory meatus of the user.

  • Patent number: 4816235
    Abstract: A method for obtaining silver and manganese metal from a silver-manganese ore includes the step of leaching the ore with acidified thiourea. More specifically, the method includes the step of leaching the ore with an acidic thiourea solution to form a leach liquor containing compounds of silver and manganese and an insoluble ore residue. The leach liquor is contacted with a quantity of activated carbon to adsorb the silver thiourea complexes on the carbon and to form an extract solution containing the manganese compounds. Next, the carbon which contains adsorbed silver thiourea complexes is contacted with an eluant to desorb the silver complexes from the carbon. The silver metal is recovered from the silver complexes obtained from desorbing the carbon. The manganese metal is recovered from the extract solution. The ore subjected to acidic thiourea leaching is selected from the group consisting of in situ ore, mined ore, comminuted ore, and ore concentrate.

  • Patent number: 4778519
    Abstract: A method is provided for recovering gold and silver from precious metal bearing materials including ores, leaching residues, flue dust, electronic scrap, jewelry scrap, etc. In the method, the gold and silver are extracted from the precious metal bearing materials with a thiourea solution to form a thiourea leach, and the thiourea leach is contacted with carbon to adsorb the gold and silver and provide loaded carbon. The method is characterized by the step of contacting an alkaline solution of thiousulfate ion with the loaded carbon thereby desorbing the precious metals form the carbon. In one modification of the method, an additional step includes adding a salt to the aqueous thiousulfate solution. When needed, the method includes the step of protecting the thiousulfate ion from oxidizing agents. This is done by adding a reducing agent such as sodium sulfite to the thiousulfate solution.

  • Patent number: 4552676
    Abstract: A lubricating composition and method are disclosed for lubricating the inner wall of a hollow conduit and the outer surface of an insulated flexible electrical conductor installed in the conduit. The lubricating composition is a powder comprised of the following powdered ingredients: lubricant such as talc; drying agent such as a micron-mesh silica; surfactant such as calcium stearate; odorant such as sassafras; and colorant such as a nontoxic food or cosmetic dye. The lubricating method first includes the step of blowing a quantity of a powdered lubricating composition into a hollow conduit resulting in the deposition of powdered lubricant on the inner wall of the conduit. In the next step of the method, an insulated flexible electrical conductor is inserted into the pre-lubricated conduit whereby powdered lubricant on the inner wall of the conduit rubs off onto the outer surface of the insulation of the electrical conductor thereby lubricating the insulation as it advances through the conduit.
