  • Patent number: 6817951
    Abstract: An improved novelty item is disclosed. The novelty item has a container that receives a solid piece of carbon dioxide when the solid carbon dioxide contacts water vapor in the container a fog is created. As the solid carbon dioxide sublimates, the water vapor is emitted from the container as a visible fog. The container may be in the shape of any number of designs for which the visible fog streaming from the container creates a pleasing illusion.

  • Patent number: 6751685
    Abstract: The present invention is primarily directed to rail car communication system and in particular communication system used to transfer data and voice communications from one car to another. The present invention has particular applicability for use in subway cars. A communication system using an E1 protocol is provided with an interface device which translates data received from a hardware device having, inter alia, a microprocessor and a universal asynchronous receiver transmitter (UART) used for serial communications such as COM 1-4. The asynchronous UART data is interfaced with the E1 channel. UART data transfers are usually done on a byte (8 bits) by byte basis but the present invention uses E1 timing and bit by bit communications. Additionally, data is normally sent at the data rate of the E1 channel not some other unrelated speed such as those used by a UART during serial communications. Also, the data is usually sent synchronously, like the E1 channel, not asynchronously, as with a UART.

  • Patent number: 6488427
    Abstract: An applicator for dispensing a product comprises an exterior top surface, an exterior sidewall, and a base. The applicator has a chamber which constitutes a reservoir for holding the product to be dispensed. The reservoir has top wall, a bottom wall and a side wall. The applicator has an orifice for dispensing product, and the orifice connects the top surface to the top wall. The chamber has a disk capable of traveling through the chamber forcing product through the orifice as it travels through the chamber. The disk has a product contact surface that contacts a major portion of the top surface when the travel of the disk is complete so that product remaining in the chamber is minimized.
