Abstract: There is provided a high precision device for measuring the color of non-self-luminous or self-luminous objects having interchangeable optical geometries for conversion from one optical geometry to another. The device interchanges a plurality of modules, each having at least one optical geometry for directing illumination from an illumination source and for collecting sample light reflected from a measured object or sample. Such optical geometries include a 45/0 geometry, sphere geometry, specular included geometry, and specular excluded geometry. Each module is removably attached to the device when measurement of the color of the sample is desired and may be separated from the device when measurement of the color of the sample is not desired. Also, each module may include removable filters for absorbing certain types of light, such as ultraviolet visible light, and blocking elements to determine the source of any reference signal.

Abstract: A method for construction of a scaleable font database comprised of data stored in a compact form for retrieval in one of several usable forms common in digital typography. The method comprises the steps, for each text character of a font collection of: generating a digital representation of the character and identifying it with respect to character code and typeface design, determining segment endpoints and associations within a model of the character, measuring actual dimensions for the associations, and determining segment descriptors for each contour segment comprising the complete outline of the character.

Abstract: A scanning apparatus providing separate fixed focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The resolution of the digitized representation of the scanned original document can be determined by rotation of at least one lens about an axis substantially perpendicular to its optic axis.

Abstract: An homogenization valve design yields improved homogenization efficiency. The length of the valve surface relative to the valve seat or land is controlled so that the overlap is limited. This allows convergence between turbulent mixing layers and a homogenization zone. Preferably some overlap is provided, however, to contribute to the stability of the valves and avoid destructive chattering.

Abstract: A cosmetic composition is provided which includes ascorbic acid (Vitamin C) stabilized by dimethyl isosorbide in a pharmaceutically acceptable carrier. Among the preferred carriers are polyols such as polyethylene glycol, propylene glycol and mixtures thereof. Aesthetic properties are improved by the presence of a crosslinked non-emulsifying siloxane elastomer and a volatile siloxane.

Abstract: This invention is directed to L5 shuttle phasmids capable of delivering foreign DNA into mycobacteria and to methods of producing L5 shuttle phasmids. In addition, this invention is directed to a method of generating mycobacterial mutations and to a method of producing mycobacterial vaccines.

Abstract: The present invention relates to liquid detergent compositions comprising substantially linear, water soluble, highly salt-tolerant non-adsorbing, ionic polymers of MW 10,000 to 1,000,000 Daltons which, when added in defined minimum levels to structured heavy duty liquids, make the liquids highly shear thinning without decreasing pour viscosity of the composition or increasing it to a point where it is too thick. The compositions are also stable.

Abstract: A tape is disclosed including a flexible substrate having a first zone and a second zone, a first layer of adhesive disposed at the first zone and a second layer of adhesive disposed at the second zone. The tape can be permanently affixed to one surface and readily removable from another surface. An attachable protective sheet arrangement includes at least one piece the tape and a protective flexible sheet. The first zone is permanently affixed to the flexible sheet and the second zone is available for attachment to a surface.

Abstract: A color mascara composition comprising from about 1 to about 99 wt. % of a natural wax modified with a C.sub.1 -C.sub.60, preferably a C.sub.20 -C.sub.40 alkanol to substantially esterify C.sub.12 -C.sub.60 free fatty acids of the wax to form an esterified wax; from about 0.001 to about 20 wt. % of a colorant; and an effective of a cosmetically acceptable carrier.

Abstract: The present invention relates to novel hydroxy-containing alkyl glycamide surfactants and detergent composition comprising said surfactants. Since they surprisingly provide low foam, these surfactants can be used as cleansing surfactants in applications where low foaming is desirable.

Abstract: The present invention relates to a dentifrice that is capable of generating heat upon use in the oral cavity. The dentifrice contains an effective amount of a heat of hydration generating hydratable inorganic or organic salt. A preferred salt is anhydrous sodium carbonate.

Abstract: An amide of a hydroxy fatty acid amide in combination with either retinol or retinyl ester resulted in a synergistic repression in keratinocyte proliferation. The effects of the retinol or retinyl esters in combination with hydroxy fatty acid amides were analogous to treatment with retinoic acid.

Abstract: An encapsulated bleach particle is provided, comprising(a) 1-30% by weight of a coating including a gelled polymer material (as herein defined);(b) 99-70% by weight of a core material selected from the group consisting of a peroxygen bleach compound, a bleach catalyst, and a bleach precursor.This particle was found to have both favourable storage stability and good solubility characteristics. Furthermore, a process for producing encapsulated particles having said composition is provided.

Abstract: The present invention relates to pretreater or compositions in stick form which remove stains. The compositions contain 30 to 80 wt. % of a nonionic surfactant, 1 to about 20 wt. % of an anionic soap, and 0.1% to 10 wt. % of a hydrophobically modified polar polymer.

Abstract: A platesetting method and apparatus provides for dimensional and/or exposure sensitivity changes in a printing plate to be imaged in a platesetter. A condition sensor senses the temperature of the plate prior to exposure so that a control unit can adjust the control commands to the scanning exposure mechanism of the platesetter in order to compensate for any thermal expansion or exposure sensitivity shifts. An image to be recorded onto the plate material has a standard size at a standard plate material temperature. When the plate material is at a non-standard temperature, as determined by the thermal sensor, a program, stored in memory, calculates a new image size based on the non-standard temperature and the thermal characteristics of the plate material which are also stored in memory. The imagesetter electronic controller then exposes an image having a size which will be the standard size when the plate material returns to the standard temperature.
