Abstract: A system and method for cleaning, disinfecting, storing and wetting rigid gas permeable contact lenses is provided. The system includes a cleaning, disinfecting and storing solution and a separate wetting solution. Both solutions contain hydrophilic disinfectants or preservatives which do not inhibit proper wetting of rigid gas permeable contact lenses. The lenses are stored in the cleaning, disinfecting and storing solution during nonwearing periods. This storage also acts as a secondary or backup cleaning treatment to help remove any residual contaminants after the primary cleaning with this solution.

Abstract: A method is provided for locating non-aqueous phase liquid in an aquifer. An aqueous solution having the capacity to solubilize the contaminating liquid to concentrations greater than the solubility of the contaminant in water is injected and produced through a well. Chemical concentrations in produced fluid samples are interpreted to locate the contaminating liquid. Produced fluid samples are chemically analyzed to determine composition of the contaminant.

Abstract: A method of disinfecting a contact lens is disclosed and comprises placing the contact lens to be disinfected into a liquid electrolyte containing chlorine dioxide precursor, e.g., stabilized chlorine dioxide, and forming a disinfecting amount of chlorine dioxide in the liquid electrolyte by passing an electric current through the liquid electrolyte.

Abstract: Process for sterilizing a contact lens using an aqueous solution of a sterilant which may be a peroxygen disinfectant, an inorganic hypochlorite compound or a hypochlorite precursor compound. The process involves the steps of contacting the lens with the aqueous solution for a period of time sufficient to effect sterilization of the lens; and thereafter contacting the resultant aqueous solution and lens with an amount of activated carbon and for a period of time sufficient to decompose substantially all of any residual sterilant to ophthalmologically innocuous by-products.

Abstract: A cell cultivating device comprising superposed, separate partition wall members forming mutually spaced partition walls, which define superposed chambers for containing a cell cultivating medium therebetween. The superposed partition wall members each comprising said partition wall and an upstanding peripheral wall extending transversely thereto, are arranged within a closed outer container having a flat bottom wall and a flat end wall. A liquid cultivating medium may be introduced into the outer container through a filling opening while the container is in an upright position in which it is supported by the end wall. The liquid may then substantially uniformly distribute itself within the cultivating chambers via a tunnel extending along the end wall and interconnecting the cultivating chambers.

Abstract: An air freshener device is disclosed herein of multilayer construction which, when laminated or joined together, provides a strong reinforced unitary structure for holding a scented member between two snap-locked layers defining an internally closed cavity that provides a moisture barrier for at least a message or picture card forming a part of the unitary structure. The device includes a pair of thin members having preformed islands, receptacles and pins which, when aligned, may be snap-locked together. A scented member is held in the central cavity defined between the snap-locked members and a plurality of passageways interconnects the central cavity with peripheral vents to release the fragrance exteriorly of the device. Message, photographic or graphic representations are carried on display cards secured to the opposite sides of the snap-locked members which are isolated from the moisture of the scent carried on the scent carrier.

Abstract: A micropositioner has a platform supported on balls positioned by inclined planes machined on plungers. The plungers are adjustable in horizontal bores in a frame which has a vertical portion with adjusting screws for horizontal positioning of the platform and rotation about a vertical axis. The micropositioner provides four degrees of freedom with four adjustable screws in one embodiment, five degrees of freedom in an alternative embodiment, and six degrees of freedom in yet another embodiment.

Abstract: There is disclosed a method and an apparatus for easily controlling the advancing direction of an excavating machine without causing the excavating machine to largely trace in a zigzag way. The direction control is done by the steps of mounting a reflector on a head portion of a shield body so as to receive a light beam directed along an imaginary reference line, mounting a target on a tail portion of the shield body so as to receive the reflected light beam from the reflector, controlling means for correcting the direction so that the reflected light beam may be irradiated at an objective position within the target, and thereby controlling the advancing direction of the excavating machine so that a subjective portion at the front end of the head portion may follow along the reference line.

Abstract: A thermal conductivity detector includes a thin diaphragm, a heat-generating portion, and a pair of boundary holes. The thin diaphragm is obtained by forming a space in part of a base. The heat-generating portion is formed in the diaphragm. The boundary holes are formed to surround the heat-generating portion.

Abstract: Rotatable circular plates are stacked apart to form thin air layers therebetween. Rotation of the circular plates moves air over an air treatment material: catalyst or adsorbent. In one embodiment, the air treatment material is affixed to the surface of the circular plates. In another embodiment, the circular plates are formed from the air treatment material. The increased velocity of air relative to the circular plates causes separation of laminar flow, promotes boundary-layer turbulence near the plate surfaces, and promotes propagating stall in the air layers. These phenomena enhance the contact between the flowing air and the air treatment material.

Abstract: A refrigerator includes a thawing compartment in which food is to be thawed through the aid of a heater. An odor absorbing member mounted along a ceiling of the compartment comprises a porous plate which carries a platinum catalyst. The catalyst absorbs odors which are decomposed upon being heated to more than 100.degree. C. by the heater. Upon being heated greater than 250.degree. C. the odors form a platinum-sulfur compound which attaches to the porous plate.

Abstract: Contaminants in an aqueous stream are oxidized with minimal use of an added oxidant by diffusing the oxidant through a fixed porous element followed by cyclical photolytic treatment of the stream with at least two different wavelengths of light. The porous element is preferably formed in one piece of a durable sintered ceramic material. The photolytic treatment preferably involves the sequential use of ultraviolet light having two different wavelengths, by which complementary oxidizing reactions occur within the stream being decontaminated.

Abstract: A method is provided to determine the concentration of an amorphous material such as blast furnace slag in a slurry such as drilling fluid, completion fluid fluids. A sample is annealed at a temperature between about 800.degree. C. and about 1000.degree. C. for a time period of about six hours to form crystals from the amorphous material, and the sample along with a known amount of a standard is then analyzed by X-ray diffraction. This method is particularly useful in determining the amount of blast furnace slag in a drilling fluid prior to conversion of the drilling fluid to a wellbore cement slurry by addition of additional blast furnace slag.

Abstract: In a diagnostic method wherein steam condensate is evaluated, the proportion of condensate water from one steam source, versus other steam sources, is determined by adding at an addition point a tracer that is selectively carried over into the steam.
