  • Patent number: 8952780
    Abstract: The present invention is a self contained, portable security case or container. The case is secure in its locked condition by locks which are preferably operated by an electronic key. The electronic key can be programmed to open the case or container dependent upon various different conditions, for example, location, time, identification of operator, etc. In addition to the electronic key, a biometric identification device can be employed. The exterior of the case or container is made from different materials which are impermeable and resistant to heat, drilling and ballistic impact. A GPS type of location device located within the case enables the case to be tracked from remote locations.

  • Patent number: 8887642
    Abstract: A cart is movably engaged with a flow control track by a pair of different height cam followers. An end track segment between parallel side leg track segments of the track contains inner and outer end channels. An intermediate wall in the end track segment forms the outer and inner end channels and cooperates with the height of the cam followers to direct one cam follower on each cart into one of the inner and outer end tracks and the other cam follower on the cart into the other of the inner and outer end channels to smoothly control the movement of the cart around the end segment between the ends of the first and second side leg track segments.

  • Publication number: 20140334127
    Abstract: The present application is directed to an illumination device comprising a recycling cavity defined by recycling surfaces and a light emission surface; a light source within the cavity. A spectrum modifying layer is on a portion of the recycling surface, the spectrum modifying layer producing a spectral response different from the spectral response of the recycling surface. In some embodiments, the spectrum modifying layer shifts the spectral properties of the light being emitted from the light emission area from the spectral properties of the light source. In some embodiments, the spectrum modifying layer selectively absorbs a portion of light along the light source spectrum. In some embodiments, the spectrum modifying layer re-emits light at a wavelength longer than the wavelength it absorbed.

  • Publication number: 20140151393
    Abstract: An article dispenser accumulates and dispenses a required correct number of articles from a supply of loose articles to complete a work operation. The articles are picked one at a time from the supply of articles and deposited on a pivotal chute for collection in a ladle at an outlet of the chute. When the correct number of articles are deposited in the chute, the chute pivots from a first article accumulation position to a second position allowing removal of the articles from the ladle.

  • Patent number: 8677849
    Abstract: A sprocket unit comprising: a damper mounted on the first shaft with a first face defining a recess and a second face defining chambers for receiving spring loaded weights; a sprocket mounted to the first shaft with a hub defining an aperture and a slot; a front end plate mounted on the shaft with a hub defining an aperture aligned with the aperture of the sprocket; and a spring received within the aperture of the sprocket, the aperture of the front end plate, and the recess of the damper. When the first shaft rotates and firing frequency of the engine coincides with a resonant frequency of the first shaft, the spring loaded weights slide in the chambers of the damper, dampening out the resonant frequency in the first shaft and when the sprocket rotates the spring compresses and extends, reducing torsional load of the first shaft on the second shaft.

  • Patent number: 8668812
    Abstract: Disclosed are examples of apparatuses for evaporative purification of a contaminated liquid. In each example, there is a first vessel for storing the contaminated fluid. The first vessel includes a surface coated with a layer of superhydrophobic material and the surface is at least partially in contact with the contaminated liquid. The contaminants do not adhere to the surface as the purified liquid evaporates, thus simplifying maintenance of the apparatus.

  • Publication number: 20130328239
    Abstract: An external covering and method of making an external covering for hiding the internal endoskeleton of a mechanical (e.g., prosthetic) device that exhibits skin-like qualities is provided. The external covering generally comprises an internal bulk layer in contact with the endoskeleton of the prosthetic device and an external skin layer disposed about the internal bulk layer. The external skin layer is comprised of a polymer composite with carbon nanotubes embedded therein. The outer surface of the skin layer has multiple cone-shaped projections that provide the external skin layer with superhydrophobicity. The carbon nanotubes are preferably vertically aligned between the inner surface and outer surface of the external skin layer in order to provide the skin layer with the ability to transmit heat. Superhydrophobic powders may optionally be used as part of the polymer composite or applied as a coating to the surface of the skin layer to enhance superhydrophobicity.
