Abstract: A transportable container for a medical specimen, preferably in the form of a Coplin jar. The container includes a jar molded from a thermoplastic material having an open top, with the lid hingedly coupled to the top of the jar for movement between open and closed positions. The top of the jar includes a rim projecting upwardly therefrom, with the lid having a recessed inside surface including a sealing ring therein shaped like the projecting rim. The sealing ring contacts the rim and seals thereagainst when the lid is closed. A snap lock latch is coupled to the lid and releaseably snap locks to a keeper on the jar to positively lock the lid to the jar to prevent leaks. The container can be used with a kit which includes a tray which receives the container in sideways fashion only.

Abstract: A method of and apparatus for generating superoxides and other free radicals for cleaning and sterilizing contact lenses tonometers and other poorly oxidizing objects in an electrolytic solution which may optionally include an antiseptic such as hydrogen peroxide enzymes and soaps and for neutralizing the above agents by using electrolysis to decompose the peroxide and to generate free radicals that neutralize the enzymes and soaps and sterilize. The apparatus includes a timer for controlling the process and indicating when sterilization and neutralization are taking place and when they have been completed.

Abstract: An apparatus and method for rapidly identifying the chemical compositions and concentrations of solutions and for discriminating among solutions of different chemical compositions and concentrations of the solution is monitored by applying across a predetermined volume of the solution a predetermined voltage for a predetermined time after which the application of voltage is terminated and the voltage time characteristic measured across the solution as the voltage decays is compared with an empirically obtained voltage versus time characteristic for a solution having a standardized composition and/or concentration.

Abstract: A lens and method of fabrication thereof for increasing depth of focus where the lens power can be a constant but the amplitude and phase of the wave across the pupillary aperture are variables. The lens can be constructed by shading regions thereof in accordance with a mathematical function, e.g., a Gaussian distribution or Bessel function over a predetermined geometry, such as e.g., concentric, parallel or radial. The lens may be of single power or multiple power, e.g., of the bi-focal type.

Abstract: A system and method for applying a disinfectant solution which may include a salt and a buffer to an instrument, object or mass wherein the solution is selectively rendered disinfecting and neutral by impressing a voltage across it to ionize an unstable salt which yields toxic ions only while the voltage is applied. The system can be used to disinfect both metallic and plastic instruments.

Abstract: An interactive video system has a video display for displaying camouflaged information which is discernible only when viewed through a partially transparent viewing screen having zones with light transmission characteristics corresponding to the characteristic of respective displayed image regions. The user of the system is required to input information which can be derived only by recognizing the camouflaged information with the aid of the screen.

Abstract: A novel aqueous solution for use in electrochemical cleaning and disinfecting is disclosed. The aqueous solution comprises hydrogen peroxide, a blend of a first ionizable salt and second ionizable salt, and a buffer, with the first ionizable salt being sodium chloride and the second ionizable salt including a metal of Group IA or IIA of the Periodic Table. Preferably a surfactant is included which is a non-ionic surfactant. Also, the preferred buffer is a phosphate buffer system. The preferred second ionizable salt is disclosed as being sodium sulfate.

Abstract: A lens and method of fabrication thereof for improving reading vision while maintaining normal vision wherein the diopter power of the lens varies inversely with the radius of the lens.

Abstract: A safety disposable needle has a shroud with a canted bore region slidably mounted thereon. A face of the shroud directed to engage the skin has an adhesive coating for fixing the shroud to the skin as the needle is withdrawn and its tip enters the shroud after which the shroud is separated from the skin as it engages an enlargement on the needle and is then canted to entrap the needle tip.

Abstract: Apparatus for applying a disinfectant solution which may include hydrogen peroxide, a salt and a buffer to an instrument wherein the instrument can be inserted into an opening in the wall of a vessel containing a disinfectant normally at a level below the opening. A floatation plunger is urged downwardly to displace the disinfectant to a level in engagement with the instrument and the electrodes are energized to activate the disinfectant. A magnetic latch holds the floatation plunger in place during disinfection and the disinfectant level is sensed to enable energization of the electrodes only when the level is sufficient to engage the instrument.
