Title: Cosmetic composition comprising thermal mineral water
Inventor: HEINRICH STEPHEN DE
IPC: A61K8/14
Filed: 2009-10-02
Abstract: A cosmetic preparation comprises at least 75% of thermal mineral waters within the aqueous portion of the formulation. The mineral content within the thermal mineral water may be rendered more bio-available by pre-fermentation with microorganisms, preferably the yeast saccharomyces cerevisiae, wherein the fermentation process leads to incorporation of the mineral within, or associated with, organic molecules that are more able to penetrate into the skin cells. The microorganisms are then lysed following their culture and cell debris is filtered from the water before use, leaving only the soluble organics with their associated minerals. Preferably, at least a portion of the thermal mineral water is incorporated into phospholipid liposomes. The cosmetic preparation may be a moisturising cream, serum or exfoliant and provides skin enhancing properties when applied topically.

Title: An improved process and machine for the grinding and/or the polishing of glass
IPC: B24B7/24
Filed: 1951-04-30
Abstract: 690,657. Grinding and polishing sheet glass. GLACERIE DE LA SAMBRE SOC. ANON. April 30, 1951 [April 28, 1950] , No. 10087[51. Class 60. A process for grinding and/or polishing the two faces of a continuously-moving glass sheet 1 comprises subjecting the sheet to the action of pairs of grinding or polishing rolls 2, the rolls in each pair being rotated at different speeds to produce a resultant frictional force in the direction of travel of the glass sheet. The grinding rolls are formed by groups of discs of cast iron or abrasive material while the polishing rolls are similarly formed by felt or felt-lined discs. The rolls of each pair, which may rotate in the same or in opposite directions, are mounted on shafts 3, driven by chains 11, and gearing 9, from motors 8, mounted on carriages 23, 26 supported on the machine frame. A link 17 pivotally connected to the machine frame and to a worm wheel driven by a worm 12 fast with the lower shaft 3 causes the latter to reciprocate axially, a lever 28 effecting equal and opposite axial reciprocation of the upper shaft. To compensate for reduction in diameter of the rolls due to wear, the speed of the motors 8, may be adjusted. Wear of the lower rolls 2' is also compensated by means of jacks 31, and a hand wheel 32 which enables the axis of the rolls to be lifted from time to time. The pressure between the rolls and the glass'is adjusted by a handwheel 5 acting through a spring 7. When a number of pairs of rolls are employed, the upper rolls of adjacent pairs are reciprocated in opposite directions to balance the transverse forces on the glass. Grinding or polishing discs mounted on bearers may be interposed between the pairs of rolls.
