A nail polish removal system (310) broadly comprises a hollow applicator handle (316) having an applicator end (318) with an absorbent material (320) attached thereto. The handle (316) has an opening (326) at the applicator end (318). The handle (316) contains a breakable capsule (328). Adjacent to the breakable capsule (328) and opposite to the opening (326), the handle (316) has a seal (330). The breakable capsule (328) is filled with up to one ounce of the nail polish removal solution. The breakable capsule (328) is broken releasing the nail polish removal solution. The released nail polish removal solution saturates the absorbent material (320) by flowing through the opening (326).

Disposable collection devices for human waste formed substantially of light weight, flexible polymeric sheets, are designed to slidingly fit over a standard, open ring toilet seat, most preferably forming an envelope which receives the toilet seat between upper and lower portions. A collection portion is disposed between portions of the envelope such that when the device is positioned on a toilet seat, the collection portion will extend downwardly permitting collection of human urine and/or feces from a patient. The collection portion preferably extends downwardly sufficiently to avoid splashing or other unnecessary contact between the patient and the waste being collected. Embodiments of the present invention advantageously comprise at least one removable collection portion. Embodiments of the present invention also comprise structures for substantially closing the collection portion after the waste has been deposited therein.

A smoke-free roaster includes a roaster body having a bottom to which a grease collection tray is mounted, a roasting grating mounted on a top of the roaster body, and a heating structure mounted inside the roaster body. The roasting grating includes grating bars, between which solid sloping plates are formed and gently inclined downward from front and rear side edges in a direction along the grating bars toward a central portion of the roaster body and the heating structure comprises reflector assemblies, which includes heating modules respectively mounted below the sloping plates and respectively receive therein carbon fiber heating tubes that irradiate and thus heat the roasting grating and comprise electrical terminals forming power supply connection modules. The sloping plates increase the surface area on the two opposite sides of the roaster body for heat transfer and heat accumulation thereby raising roasting temperature on the two side portions.

A sample, which has a mesa portion having a pattern thereon, is placed on a Z table. Light is irradiated to the mesa portion through an optical system and light reflected by the mesa portion is received to measure a height of the mesa portion. A height map of the mesa portion is created based on a height of a corner position. A height using the height map is corrected based on a deviation of a measured value from a target value, and a temporal variation of a focal position of light irradiated to the mesa portion. An optical image of the pattern is obtained while controlling the Z table based on the corrected height of the mesa portion. The optical image is compared with a reference image and a defect is determined when a difference value between the optical image and reference image is more than a predetermined threshold value.

A disposable food container forms a pouch or pocket having a closed ends and sides, as well as a mouth or opening. A substantially rigid member forms the opening of the mouth to provide support to the container, and to permit only a desired amount of food to extend out of the mouth of the container. A user can easily control the amount of food that protrudes out of the container by applying pressure to the outside of the container and pushing only a desired amount of food out of the mouth of the container. The remainder of the food remains enclosed within the container, thereby preventing unwanted touching of such food and spillage.

Plant material for ensilage is harvested using at least one harvesting vehicle in the field, is hauled to a silo and is compressed using a compression device. The compression output of the compression device is compared to the harvesting output of the at least one harvesting vehicle, and a command to increase the harvesting output or to decrease the harvesting output of the harvesting vehicle (1) to a non-vanishing value is generated when the harvesting output deviates significantly from the compression output.

A hair coloring applicator may include a handle portion and an applying portion. The applying portion may include a first applying element and a second applying element. In one aspect, the hair coloring applicator may be scissor-shaped. In another aspect, the hair coloring applicator may be clamp-shaped. The hair coloring applicator in the present invention is advantageous because it is much easier for the user to control the applicator to apply the dye(s) on the hair, and more importantly to a specific strand of the hair, even including the portion closed to the root of the hair to cover grey roots effectively. Also, the dyes or the hair treatment materials are unlikely to spread out to other portions of hair. Moreover, the hair coloring applicator can eliminate unnecessary contact between the scalp and the dyes.

The invention relates to a high-efficiency purification electrostatic dust collector, aiming at solving the problem that the dust removal efficiency is reduced, caused by reverse corona and secondarydust rising. The high-efficiency purification electrostatic dust collector comprises a gas inlet, a gas outlet, a dust collection plate, a discharging wire and an ash bucket, wherein the dust collection plate is provided with an ash cleaning device; ash cleaning boxes with a special design are adopted and are used for squeezing dust swept by an ash cleaning brush at the top of the box body, so that the secondary dust rising is avoided; two ash cleaning boxes form one group, and form a loop through a rope; when one ash cleaning box is ascended, the other ash cleaning box is descended to clean ash. The ash cleaning brush is designed to keep vertical with the dust collection plate in an ash cleaning process; when the ash cleaning brush is ascended to be reset, a brush head is folded, so thatthe service life is prolonged. According to the dust collector provided by the invention, the disadvantages of a conventional electrostatic dust collector that the specific resistance is high, ultrafine dust and high-viscosity dust are difficult to collect and clean, the secondary dust rising is easy to cause and the like are overcome, and the defects of a bag dust collector that the equipment resistance is great, the operation cost is high, the working amount of daily maintenance is great, high-temperature and high-humidity flue gas is difficult to treat and the like are also made up; the high-efficiency purification electrostatic dust collector is simple in structure, high in ash cleaning efficiency, low in cost and easy to maintain.
