Abstract: A composition of certain dyes with a category-2 hair bleach can simultaneously lighten hair up to seven levels and deposit various shades of color in a single step. The dyes are bleach-stable derivatives of azo, triarylmethane, thiazine, or nitro dyes. When linked at the ortho- and/or para-positions relative to the chromophoric centers and auxochrome groups located on or attached to the aromatic rings of these dyes, deactivating or weakly activating chemical groups enhance the dye stability in the alkaline bleach. The absence of ortho and/or para positioned deactivating or weakly-activating substituents, or the presence of strongly activating groups in these positions render the dye molecule susceptible to attack by the bleach and the eventual destruction of these dyes. These deactivating and protective chemical groups may be nitro, halogen, cyano, carboxyl, sulfonic, alkyl or aromatic groups, but not amino, hydroxy, alkoxy or alkylamide groups.

Abstract: A storage unit for storing a bicycle or the like has an overall vertical dimension greater than an overall horizontal dimension, such that the storage unit provides an enclosed area for storing the bicycle in a substantially inclined position. Specifically, the storage unit stands upright or "on end" for storing the bicycle in the inclined position. As such, ground surface area usage is minimized. The storage unit includes an inclined ramp within the enclosed area for providing lift to a wheel of the bicycle as the bicycle is moved into the enclosed area and into the substantially inclined position. A tire-stop cross member is disposed within a lower portion of the enclosed area for providing support to a wheel of the bicycle for retaining the bicycle in the substantially inclined position. The storage unit comprises a plurality of modular panels and may be combined with other storage units such that a common wall is shared between any two adjacently joining storage units.

Abstract: In accordance with the present invention, there is provided a single-step process and composition of a category-2 hair bleach which can simultaneously lighten the hair up to seven levels, and effectively neutralize any undesirable warmth that accompanies the lightening process. This is achieved by including in the bleach composition disperse dye molecules which the present invention has found to be both, stable in the bleach, and capable of depositing the desired amount of various permanent tones on the hair. These disperse dyes do not stain the scalp of the client or the hands of the hairdresser, but are substantive only to the hair fibers. The dyes fall into the classes of anthraquinones and azo compounds.

Abstract: This invention describes a process for the removal of exogenous minerals which have become attached to human hair or keratin fiber which include the steps of contacting at least one chelating agent to the human hair or keratin fiber, the chelating agent selected from the group consisting of amino acid-type, polyphosphate-type and phosphonate-type agents, maintaining contact with the chelating agent and the human hair or keratin fiber for a period of time sufficient to permit the chelating agent to complex with the exogenous minerals, thereby removing at least a portion of the attached minerals, and rinsing the chelating agent. The process is enhanced with the pH is adjusted to a range of between 4 to 9, preferably 5 to 8. The chelating agent is added at a concentration of 4% by weight to 25% by weight, preferably 5 to 20% by weight.

Abstract: An electronic combination lock is disclosed which allows access to a closed or secure location wherein the lock includes a locking mechanism for operating between a locked condition and an unlocked condition. A rotatable cam wheel has a circumferential surface portion defining a slot such that rotation of the cam wheel moves the slot. A movable lever is coupled to the locking mechanism for changing the condition of the locking mechanism from the locked condition to the unlocked condition and is pivotably movable into and out of engagement with the cam wheel. The movable lever engages the cam wheel such that rotation of the cam wheel changes the condition of the locking mechanism. A cantilever and detent on the lever releasably maintain the lever in a position disengaged from the cam wheel.

Abstract: An electronic lock for a safe door is provided with a digital keypad entry device, a mechanical bolt works and associated handle for retracting the door bolts, and a spring biased rotary bolt which engages and precludes operation of the bolt works, such that upon entry of the predetermined code into the entry device, an electric signal causes a solenoid to energize and retract its armature from a blocking position relative the rotary bolt, further enabling the rotary bolt to rotate against its bias in response to mechanical manipulation of the handle by the user to retract the door bolts. Unauthorized operation of the safe handle causes the rotary bolt to be locked into a fixed position, preventing entry into the safe.
