Abstract: The present invention is a topical film-forming composition comprising; (a) a non-toxic volatile solvent, (b) a cellulosic material having at least one hydroxyl group on a side chain of a cellulose backbone, (c) an esterification agent capable of reacting with said hydroxyl group on the side chain of said cellulosic material to form an ester, and (d) a glycerol monolaurate crosslinking agent. Various medicinal, antibiotic, anitfungal, anesthetic, analgesic and virucidal agents may be included within the composition.

Abstract: There is disclosed a method for treating skin along with a novel skin care composition comprising the following components in a suitable carrier:(a) from about 1 to about 10 weight percent of a cyclodextrin material; and(b) from about 1 to about 15 weight percent of an acid material selected from:alpha hydroxy acids, beta hydroxy acids, alpha keto acids, beta keto acids, and combinations thereof.The skin care composition includes a cyclodextrin material to reduce the irritation and stinging caused by the presence of the aforementioned acid materials.

Abstract: The present invention is a skin care composition which provides a high degree of moisturization without leaving a "tacky" residue on treated skin. The subject composition comprises; (a) from about 2 to about 10 weight percent of a quaternary ammonium compound having the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each alkyl groups having from about 16 to about 22 carbon atoms, R.sub.3 and R.sub.4 are each lower alkyl groups having from about 1 to about 3 carbon atoms, and X is a salt-forming anion, (b) from about 1 to about 40 weight percent of a humectant, and (c) from about 0.01 to about 5 weight percent of non-irritating hydrophobic polymeric microspheres having an average particle size of less than about 50 microns.

Abstract: A oil-in-water emulsion for treating the skin comprising from about 2 to about 10 weight percent of a cationic emulsifier such as dimethyl distearyl ammonium halide, a substantially nonionizable humectant such as glycerine and a weakly acidic material having a disassociation constant of about 1 to 6. The amount of weakly acidic material is such that the pH of the finished emulsion is about 2.5 to 4.5. Also disclosed is a method of preparing the emulsion.

Abstract: The present invention is directed to a method of forming an oil-in-water emulsion containing water-insoluble components, a water-soluble humectant, a weakly acidic component such as an alpha-hydroxy acid and a quaternary ammonium cationic emulsifier. The emulsion is used as a stable skin care cream.

Abstract: An off-center NMR image is produced using an EPI pulse sequence. The offset along the readout gradient axis is achieved by shifting the frequency of an RF reference signal used to demodulate the received NMR echo signals. Phase errors produced by the NMR system and by the shifts in reference signal frequency are corrected in "real time" by also shifting the phase of the RF reference signal.

Abstract: A motion encoder includes a code member that extends along the route of the object whose movement is to be encoded, an energy emitter, and a modulated energy detector assembly. An incremental movement modulation track and two index modulation tracks are positioned on the code member for modulating the emitted energy in response to movement of the object along its route. The energy detector assembly includes an incremental movement energy detector and two index energy detectors. The two index modulation tracks are positioned on opposite sides of, and are each spaced a substantially equal distance from the incremental movement track. Similarly, the two index energy detectors are positioned on opposite sides of, and are each spaced a substantially equal distance from the incremental movement energy detector.
