摘要:
A two or more part dispenser is provided having an elongated flexible housing which defines an interior chamber. A disc(s) is contained within the chamber and is movable from a closed to an open position. In its closed position, the disc(s) divides the chamber into two or more subchambers, each of which contains a different liquid. A collar is slidably mounted to the housing and coaxially disposed around each disc to maintain the disc in its closed position. Upon displacement of the collar away from the disc, a finger on the collar compresses the housing an displaces the disc to its open position thus allowing the two or more liquids in the subchambers to intermix together. A dispensing nozzle assembly having an outlet is fluidly connected by a fluid passageway to the housing chamber. A normally closed valve is positioned in series with this passageway so that, when the valve is moved to its open position, liquid within the housing chamber is dispensed out through the nozzle outlet.

An apparatus for field testing anemometers which utilizes an uncalibrated industrial hand blower powered by a constant pre-determined voltage is shown and described.A method of calibration against a standard anemometer and a method of field testing anemometers by use of an apparatus using an industrial hand blower are described.
摘要:
An interconnect includes a first set of connector pads, a second set of connector pads, and a continuous central portion. A first plurality of legs extends at a first angle from the continuous central portion. Each leg of the first plurality of legs is connected to a connector pad of a first set of connector pads. A second plurality of legs extends at a second angle from the continuous central portion. Each leg of the second plurality of legs is connected to a connector pad of the second set of connector pads. Gaps are defined between legs. The gaps enable movement of the first set of connector pads relative to the second set of connector pads.
摘要:
A solar powered lamp configured to function more efficiently at elevated temperatures. The solar powered lamp comprises an electrical storage device disposed in heat transfer proximity to a solar cell array. The electrical storage device is adapted to increase its acceptance of charge, provided by the solar cell array, at elevated temperatures. The solar powered lamp is also configured to permit flow of air through the lamp and to be assembled and disassembled with ease.
摘要:
A solar powered lamp utilizing cold cathode fluoresecent illumination and means for facilitating same. The solar powered lamp is powered through the utilization of photovoltaic cells which charge a battery for providing power to a cold cathode fluorescent bulb in the absence of sunlight. The cold cathode fluorescent bulb provides increased illumination and a longer lamp life. The solar powered lamp comprises circuitry for converting the low power provided by the battery into an alternating current voltage sufficient to operate the cold cathode fluorescent bulb in order to facilitate a longer lamp life and provide increased illumination. In a preferred embodiment, a lens configured with vertically disposed ribs about its inner surface is disposed about the cold cathode fluorescent lamp, which is vertically disposed within the lamp, to further enhance illumination.
摘要:
A self-contained solar powered marking light. The marking light may be utilized to delineate certain predetermined boundaries without effectively illuminating the areas. The marking light automatically illuminates when output power from the photovoltaic cells contained therein fall below a predetermined level and automatically extinguishes when the voltage from the photovoltaic cells reaches a predetermined level. The marking light includes a lens which is closely coupled to a source of light and which includes a textured surface for diffusing the light to cause the lens to appear to glow when the source of light is illuminated. An electrical circuit is coupled between the photovoltaic cells and a battery and includes the source of light and switching means for automatically illuminating the light dependent upon the relative relationship between the voltage of the photovoltaic cells and the battery voltage.
