  • Replaceable signal cable making a sound-controlled or externally dialed hand-free system universally compatible with all types of cellular phones
    Patent number: 6411823
    Abstract: A replaceable signal cable for connection of a specific type of cellular phone to a sound controlled or externally dialed hand-free system enables the hand-free system to be adapted for universal use on all types of cellular phones by simple selection of a proper signal cable in use. In other words, it relates more particularly to a signal cable for a hand-free system, which can be selectively replaced with ease so as to make all types of cellular phones universally adapted to one single hand-free system. The signal cable is equipped with a first connecting plug coupled with a cellular phone and a second connecting plug connected to a hand-free system. A dial-decoding IC or circuitry housed in either the first connecting plug for a cellular phone or the second connecting plug for a hand-free system is adopted according to codes set by a standard communication protocol for each type of cellular phone.

  • Eutectic mixtures in cosmetic compositions
    Patent number: 6410036
    Abstract: The present invention relates to a liquid, substantially anhydrous eutectic mixture comprising a principal acid component, such as a hydroxy acid, and at least one other component selected from the group consisting of a carbohydrate, a polyol, an amino acid, and a carboxylic acid. The mixtures remain liquid at room temperature, are relatively non-irritating, and can be used to deliver higher levels of the principal acid than would ordinarily be possible. The invention also provides a method of making such a mixture comprising heating the component having the lowest melting point to the temperature at which it melts, dissolving the remaining component or components in the melted component, and allowing the mixture to cool.

  • Methods of dispensing liquids from pouring heads
    Patent number: 6409046
    Abstract: Methods of pouring liquids from bottles have the steps of providing a pouring head with at least two functionally different modes of pouring, i.e. electronically timed pouring with automatic shut-off, and free pouring either with or without an annunciator signal, and the step of selecting one of the modes at the time of dispensing. Further, the steps of providing a normally open magnetically latched valve, and momentarily de-magnetizing to drop the valve and terminate pouring, and the steps of shaking the valve back on to magnetic and electrically sensing the presence of the valve and electrically starting a subsequent pour while the bottle remains inverted. A further step has free pouring with sensory annunciation of the completion of pouring, with the preferred annunciation being a blinking light signal.

  • Control valve for extreme temperatures and pressures
    Patent number: 6405996
    Abstract: A valve capable of controlling fluid flow at high temperatures and high-pressures. The valve can shut off or regulate flow and combines a small compact shape with the ability to be remotely operated and the ability to process a diverse variety of fluids including polymer melts at extreme temperatures and pressures including two phase fluids. The valve includes a process diaphragm that deflects to seat against a valve seat, a control diaphragm that deflects to contact against a stop surface, and a cylindrical actuating button therebetween. The actuating button has respective end surfaces that contact against the process diaphragm and the control diaphragm. The button end surfaces on the button are spaced apart by a button length. When assembled, the distance between the valve seat and the stop surface is greater than the button length by about the sum of the deflections of the diaphragms.
