A two-piece, adjustable width merchandising tray for the organized display of multiple product containers. Two L-shaped tray sections, formed of plastic material. The bottom portions of the two L-shaped sections are provided with laterally extending, interengaging fingers that enable the width of the tray to be adjusted for different product sizes while maintaining substantial continuity to the surface of the bottom structure for containment of product leakage. An asymmetrical side wall arrangement with a forwardly projecting hand grip at the front of one of the side walls enables individual trays to be removed and replaced from a closely packed array of trays arranged in side-by-side fashion. The trays can be conveniently lifted and carried for product restocking, reorganizing, tray cleaning, etc. A simple pull strip and paddle arrangement enables product to be fronted at all times. Double stacking of product containers is also accommodated. Densely stacked, attractive, and efficiently serviced product displays are facilitated.

An improved biopsy kit for the collection, storage, transportation, and processing of biopsy tissue samples is disclosed. The disclosed biopsy kit consists of a typical specimen container and an improved tissue cassette with adhesively attached polyvinyl alcohol foam pads on both the base and lid portions. An excised tissue sample is sandwiched between the pads upon cassette closure, simultaneously isolating and securing the sample in its original orientation. Superior wicking, absorbency, and moisture retention rate of these polyvinyl alcohol pads allows maximum tissue fixation as well as maintains sample integrity. Once the tissue is placed by the physician at the patient's side, it remains there until the tissue is ready to be processed. This eliminates transfer errors as well as tissue loss.

A vertical cellular blind includes a headrail having first and second tracks; a fabric carriage including a trolley translatable along one of the tracks and a fabric stem releasable connected to the trolley; a cellular fabric panel connected to the fabric stem; a vertical rail bracket translatable along the other of the tracks in the headrail and including a component angularly adjustable relative to the headrail; a vertical rail attached to the panel and connected to the vertical rail bracket; a cord having ends secured in the headrail and extending through the panel and the vertical rail; and a locking handle in the vertical rail having the cord extended therethrough and releasable pinching means in the handle for engaging the cord.

A purification apparatus, kit and method for purifying DNA, RNA, proteins, antigens, antibodies and cells. The apparatus has a wand and a reservoir tube. The wand is made of a cap, a sample collection assembly and an elongated shaft connecting the cap to the sample collection assembly. The sample collection assembly has a series of microstructures on its surface, or microparticles enclosed within it for increasing the surface area of the sample collection assembly. The increased surface area permits maximum exposure to and binding of target molecules thereto. The reservoir tube associated with the wand has one end defining an opening and a second end that is closed and preferably cone or cylindrical shaped. The cap of the wand securely and sealingly fastens to the open end of the reservoir tube with the shaft and the sample collection assembly fitting easily inside the reservoir tube. The apparatus, kit and methods can be used for protein and nucleic acids detection by calorimetric, luminescent, fluorescent or electrochemical means through attachments for detecting such signals. The apparatus, kit and methods can also be used in conjunction with an attachment for thermal regulation to perform nucleic acids amplification. The apparatus, kit and methods can further be configured for integrated, high throughput purification and detection of proteins and nucleic acids.

When exposing a same resist layer of a wafer a plurality of times, at least in one exposure of the plurality of exposures, by filling a space between a projection optical system, which projects an exposure light on the wafer, and the wafer with water by a liquid supply/drainage unit, a substantial wavelength of exposure light that reaches the wafer is made to differ from a substantial wavelength of exposure light in another exposure. Accordingly, exposure with high precision and high throughput can be achieved.

A controlled-release dosage form of azithromycin having an improved side effect profile; a process for preparing the dosage form; and a method of treating a microbial infection, comprising administering azithromycin in such a controlled-release dosage form to a mammal, including a human patient, in need of such treatment.

A wind turbine for generating electricity is configured as a drum with a housing that has adjustable shutters to control the amount of wind reaching the turbine blades. Alternatively, the turbine blades can be pivotably mounted and opened and closed using a cam follower, cam track system to minimize wind exposure to downstream turbine blades.

A rotisserie convection oven including a rotatable drum assembly which allows cooking of food items therein without added cooking oils is disclosed. The present oven is designed for cooking of pre-prepared or frozen foods with minimal ingestion of cooking oils and residual oil byproducts of concern to the health-conscious consumer. The present oven provides a countertop appliance having an enclosed cooking chamber with tubular heating elements wherein a rotatable drum containing foodstuffs is coupled to a rotisserie drive assembly. An integrated control chamber protects electrical components and encloses a convection fan assembly which is disposed in air transfer communication with the cooking chamber to enable circulation of air across the heating elements and through the rotatable drum during the cooking cycle. In one embodiment the rotatable drum is constructed of wire mesh to permit the continuous circulation of heated air therein to reduce cooking temperatures and shorten the cooking cycle.

A method of treating a subject is provided. The subject is placed in a garment or the garment is placed on the subject so as to cover a portion of the surface area of the subject with the garment. The garment is substantially transparent to a predetermined range of wavelengths. The subject is then exposed for a period of time to a light source that includes light having all or a portion of the predetermined range of wavelengths. A therapeutic clothing apparatus consisting of a blanket or hat is provided. The blanket or hat is made from a fabric that is substantially transparent to visible wavelengths.

A male and female sexual enhancing device for enhancing a flaccid penis and providing sexual stimulation to a vagina. The sexual enhancing device permits for a minimal coverage of a penis surface area, while also allowing enhanced sexual stimulation for both the male and female through the utilization of a rigid, extended assembly that enhances the flaccid penis. The components that create the enhanced erection include a bulbous distal member for extending and widening the penis. Also, two annular members receive and support the penis and reduce blood flow to the penis. A longitudinal stiffening rod provides perpetual rigidity to the penis, and a plurality of convex stimulators positioned onto the erection enhancing device maximizes sexual stimulation. Vaginal stimulators such as clit ticklers and vibrators attach along the shaft base for stimulating the vagina. The sexual enhancing device is utilized by the male and the female together or alone.

Systems and methods are presented for acquisition and processing of spectrally dispersed illumination optical coherence tomographic data. Light from a source is distributed spectrally on the sample, and each acquisition simultaneously provides partial spectral interference information from multiple locations in the sample. Thus for a given spatial point, a single observation will be of a partial spectrum A-scan. When multiple partial spectrum A-scan observations are made at the same point by shifting the spectrum of light on to the tissue, the point can be observed by the entire broadband spectrum of the light source, thereby making it possible to create a full axial resolution A-scan.

The invention is aimed at providing a method and apparatus to prepare cold brewed beverage from contaminated water. This invention is very useful for people engaged in outdoor activities like hiking, camping or backpacking who find it extremely difficult to either find a supply of potable water or carry pre-packaged beverages.
