An improved wrapping lotion and permanent waving process is disclosed. The improved waving process produces hair styles characterized as bouncier, more full bodied with an open/looser pattern of curls. The waving process is a step-by-step procedure involving the addition of a rearranger, a wrapping lotion, and a neutralizer, with intermittent rinsing between. The improved quality and setability of the hair is believed attributable to the improved wrapping lotion composition that comprises a homogenous mixture of a guar component and a salt of thioglycolic acid. A preferred wrapping lotion composition includes between about 0.2 and about 2.5% by weight of a nonionic hydroxypropylated guar and between about 0.3 and about 7.0% ammonium thioglycolate. The wrapping lotion composition should also be pH adjusted to between about 7.0 and about 10.5 and have a viscosity in the range from about 500 cps to about 12,000 cps.
The present invention provides a process by which smoothness, body and a permanent wave pattern can be imparted to multi-textured hair of all types, from hair having an excessively tightly curled appearance, such as Negroid hair, to hair having a straight appearance, such as Caucasian hair, with substantially less damage to the hair. The process of the present invention uniquely combines the use of two hair structure altering chemicals--an alkaline hydroxide (such as sodium hydroxide) and a thioglycolate reducing agent (preferably ammonium thioglycolate)--to harmoniously bring about a desired wave pattern in the hair. Using the Wave Balance Scale (a hair reference scale) of the present invention, a sodium hydroxide formulation is chosen based on the type and natural curl level of the hair. The sodium hydroxide formulation is applied to the hair for a time sufficient to relax the natural curl in the hair by breaking some of the sulfide bonds in the hair. Then, after rinsing but prior to any neutralization, the ammonium thioglycolate formulation is applied to the hair and the hair is placed on curling rods for a time sufficient to rearrange the wave pattern of the relaxed hair. The hair is then rinsed and neutralized, while still rodded, for a time sufficient to lock in the new wave pattern by reforming the sulfide bond linkages. After neutralization, the hair can be shampooed, conditioned and styled either curly or straight as desired by the patron.
5438723 - Collapsible bed and panel hinge - Owned by Carroll Equipment Sales Corporation (London,CA) [*] Notice:The portion of the term of this patent subsequent to November 2, 2010 has been disclaimed.
A hospital bed, particulary suitable for home use comprises a plurality of sections which can be releasably connected together, and can be assembled for delivery and storage with head and foot sections, and head and foot boards stacked on a seat section. When thus assembled the bed can be put into a box and for ease of movement wheels project through the bottom of the box. The various sections and parts are releasably connected by pairs of brackets which clip together, the brackets held together by a clip which prevents disengagement. Power means are provided for raising the head section panel and the foot section panel. The bed has fixed legs which are provided with wheels. Movable legs can also be provided, extendable and retractable. When the movable legs are extended the fixed legs are raised, the wheels clear the floor. Head, foot and seat panels are joined together for articulation by means of a novel hinge.
