Abstract: A new UVC sterilization device for elevator buttons, which comprises of several UVC LEDs on an enclosed polymer body, equipped with an infrared sensor to provide signals when an object comes within a certain distance, along with a controller printed circuit board that drives the unit by providing a constant current for the disinfection LEDs, as well as a battery. The infrared sensor is connected with the MCU control unit in the main body through the infrared detection unit. The MCU control unit is connected with the LEDs through the LED control unit. The main body is mounted on the elevator wall by two brackets. These brackets mechanically hold the main body in place and align the LED rays towards the buttons. The product is small and compact, easy to carry and install, and proven to be effective against microbes which would ultimately reduce bacterial and virus transmissions.

Abstract: Presented is an ergonomic wristband or a watchband for a wrist wearable device such as a smartwatch. The proposed wristband is structurally designed in a way to position the face of the wrist wearable device in a natural line of sight or convenient line of sight for a wearer. The proposed wristband when worn by the wearer would require no rotation or least rotation of the wearer's hand while viewing the face/display portion of the wrist wearable device mounted over the wristband.

Abstract: A birdfeeder that is easy to disassemble and clean and re-assemble. The birdfeeder further having a configuration such that it can be affixed to like birdfeeders to increase the amount of birdfood being offered.

Abstract: A receptacle suspended from a support member having a hollow housing and a lid to enclose the interior thereof. A cable secured to the housing extending though a locking mechanism affixed atop the lid so that the lid may be moved from a closed to an open position.

Abstract: An illumination device comprising: (a) a substantially spherical and semi-transparent gazing ball having a base with a sidewall; (b) a base cap with a channel corresponding to the sidewall of the base of the gazing ball; (c) an LED device within the base cap; (d) a battery in electrical communication with the LED device and (e) a switch for establishing and removing the electrical communication between the LED device and battery.

Abstract: The present invention discloses an innovative hummingbird feeder. The feeder of the present invention is comprised of a main body, a stopper for the main body and several feeding port assemblies. The present invention allows the consumer to engage stoppers at each feeding port assembly, these stopper prevent spillage during refilling of the nectar reservoir. Additionally, the feeding port assemblies allow access to hummingbirds but prevent access by pests, while presenting a flower-like appearance to the birds.

Abstract: A centerpiece assembly comprising: (a) a base unit capable of supporting a plurality of illumination devices; and adapted to receive ornamentation; (b) at least one imitation candle; wherein the imitation candle includes a light source; a cavity; and a power supply; wherein the power supply is a replaceable battery; and wherein the power supply is adapted to be operationally coupled to an external electronic device via a DC socket; and (c) a support receptacle for each imitation candle; wherein the receptacle is attached to the base unit and is adapted to receive the artificial candle.

Abstract: A coal preparation plant separates a low specific gravity clean coal fraction from a high specific gravity refuse fraction, and separately processes those fractions. Run of mine coal having particle sizes up to about 4 inches is mixed with a slurry of water and magnetizable particles, and is introduced into a heavy media cyclone to separate the high and low specific gravity fractions. The high specific gravity refuse fraction is delivered to a first magnetic separator to extract the magnetizable particles, while the low specific gravity clean coal fraction is delivered to a second magnetic separator to remove the magnetizable particles. The system is highly efficient and has a high processing capacity.

Abstract: An automatically operated soap dispenser for use in washing the hands of a user is provided in a housing. Enclosed in an intermediate portion of the housing is a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof. Residing in the upper portion of the housing is a disposable liquid soap container having extending from the bottom thereof a resilient elongated tubular member with a self-sealing nipple valve on the lower end thereof which is positioned in the opening on the upper wall of the cylindrical chamber. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of liquid soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the open front of the cylindrical chamber.

Abstract: An automatically operated soap dispenser and hand dryer are provided in a single housing. The housing encloses a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof opposite which a self-sealing nipple valve on the end of a tubular member of a disposable liquid soap container resides. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the cylindrical chamber The automatic hand dryer located in the housing below the cylindrical chamber provides for automatically discharging warm air through an outlet thereof in response to the hands of the user being positioned adjacent thereto.

Abstract: A magnetic separator to separate fine particles or ferrosilicon of magnetite from water. A drum is provided which rotates counter to flow of water past the drum. Magnets are provided within the drum to attract magnetite or ferrosilicon in the water to the drum.

Abstract: Methods and apparatus for drying fine coal including a heating member within a drying chamber, tumbling and agitating the coal, and allowing dried coal to escape from a drying zone through screens.

Abstract: A bouyant hanger unit comprises an elongated body molded of plastic to provide a clip on the bottom end thereof for holding a dental film chip in the plane of the hanger unit. The hanger unit has a circular projection on one face thereof axially aligned with a circular recess on the opposite face thereof. Such a construction enables a plurality of hanger units to be assembled face-to-face while permitting any of the hanger units to be pivoted away from the remaining hanger units in the assembly for the purpose of examining the dental film chip clipped on the bottom thereof. When the individual hanger units or an assembly of the hanger units with dental film chips clipped on the bottom thereof are placed in a solution they float in an upright position with the upper end thereof extending above the surface of the solution.
