Abstract: The present invention is directed to a method of applying a pasty composition for cleaning and/or deodorizing a sanitary ware, wherein the composition is suitable for direct application to the surface of the sanitary ware.

Abstract: The present invention relates to a cleaning and/or deodorizing pasty composition for sanitary ware, wherein the composition comprises a detersive surfactant and further comprises dispersed water soluble particles capable of absorbing water.

Abstract: A method of cleaning the interior surfaces of a non-loaded washing machine or a non-loaded automatic dishwasher with a liquid composition, by forming in said washing machine or automatic dishwasher an aqueous liquor comprising water and said liquid composition, wherein said liquid composition comprises an acid system comprising formic acid and an acid forming a slightly water soluble calcium salt.

Abstract: The present invention relates to a method of cleaning the interior surfaces of a non-loaded washing machine or a non-loaded automatic dishwasher with a particulate composition by forming in said washing machine or automatic dishwasher an acidic aqueous liquor comprising water and dissolved or dispersed therein said particulate composition, wherein said particulate composition comprises an effervescence system and sufficient acid to form an acidic aqueous liquor having a pH of below about 4.

Abstract: The present invention describes a method of removing soap scum from a hard-surface comprising the step of applying a liquid aqueous acidic composition onto the hard-surface, wherein the composition comprises phosphoric acid and a nonionic surfactant. The above composition when used according to the method of the present invention, exhibits improved cleaning performance on soap scum while delivering also excellent limescale removal performance.

Abstract: The present invention describes liquid aqueous acidic cleaning compositions suitable for removing limescale, comprising an acid system, wherein said acid system comprises formic acid and an acid forming slightly water soluble calcium salts. The compositions of the present invention deliver excellent limescale removal performance as well as outstanding greasy soap scum cleaning on hard-surfaces.

Abstract: A device for gluing together two disc halves which are each provided with a central hole, to produce a disc, for example an optical data carrier, such as a DVD, includes a rotatable carrier provided with a mandrel on which the disc halves can be accommodated, in such a manner that the mandrel fits through their central holes. Furthermore, there is a radially displaced light radiation source which emits a light beam which can be displaced in the radial direction with respect to the mandrel.

Abstract: An apparatus for the automated production of ophthalmic lenses, particularly compound lenses having a plastic coating on a plastic lens is described. A mold, after rotational orientation, is placed in a gimbal assembly to provide for the proper tilt. This gimbal assembly forms part of a fixture attached to an indexing means which moves for complete assembly of a molding fixture and then moves the molding fixture through a chamber to cure the resin. A preform, after rotational orientation, is held, by a preform gripper placed above the mold, and with sufficient clearance between the mold and the preform to allow the correct resin thickness during the curing portion of the process. The fixture is also provided with members to firmly grip the preform gripper so as to maintain its orientation throughout the curing process.
