Abstract: Dental cream in contact with a polyolefin resin surface of a package such as a laminate tube, a mechanical dispenser or a flexible sachet. The dental cream contains a dentally acceptable water-insoluble alkaline earth metal salt, a liquid vehicle, a gelling agent and an additive which prevents syneresis. The liquid vehicle contains water, glycerine and sorbitol. The additive which prevents syneresis due to contact between the dental cream and the polyolefin resin is a nonionic block copolymer containing moieties of polyoxyethylene and polyoxypropylene.

Abstract: Cordierite compositions having increased porosity and improved thermal expansion characteristics are disclosed. The cordierite compositions comprise from about 0.025 to about 1.5 percent by weight germanium dioxide and exhibit reduced CTE. The cordierite compositions are made by heating a mixture of kaolin, talc, alumina, kyanite and germanium dioxide to temperatures of between 1350.degree. and 1475.degree.C. The cordierite compositions are preferably made from a mixture which includes a calcined material, such as calcined talc, so that the mixture is more easily processed and the resulting cordierite compositions are more porous, and thus, more easily coated.

Abstract: Dental cream in contact with a polyolefin resin surface of a package such as a laminate tube, a mechanical dispenser or a flexible sachet. The dental cream contains a dentally acceptable water-insoluble alkaline earth metal salt, a liquid vehicle and a gelling agent. The liquid vehicle contains water, glycerine and sorbitol and, as an additive to prevent syneresis due to contact between the dental cream and the polyolefin resin, polyethylene glycol of average molecular weight or about 200-1000.

Abstract: Dentifrice containing a compound which provides fluorine, amorphous silica polishing agent and an additive which supplies calcium ions. The dentifrice is compatible with an unlined aluminum container.

Abstract: Dentifrice composition comprising sodium monofluorophosphate and compatible polishing material, at least a major portion of which is dicalcium phosphate dihydrate having a particle size such that all particles are above 3 microns in size at at least 65% of the particles are about 3-10 microns in size.

Abstract: Dental cream suitable for use in an unlined aluminum container comprising between about 35% and 60% of abrasive containing alumina as the major abrasive component and as agents to render the dental cream compatible with an unlined aluminum container, calcium carbonate present as minor abrasive component in amount of at least about 1% of the dental cream and a dissolved or dispersed silicate present in amount of about 0.05%-0.25%. The composition also desirably contains a water-soluble monofluorophosphate salt in amount which provides 0.01-1% fluoride in the dental cream and when the dental cream contains the monofluorophosphate salt and more than about 5% calcium carbonate, an alkali metal tripolyphosphate in an amount up to about 1.5% is also present.

Abstract: Dentifrice containing a compound which provides fluorine, amorphous silica polishing agent and an additive which supplies calcium ions. The dentifrice is compatible with an unlined aluminum container.

Abstract: A covered book comprises: a stack of aligned sheets, including a front and back cover, providing an edge surface; a first protective sheet located adjacent the outside of the front cover; a second protective sheet located adjacent the outside of the back cover; and a binding strip fixed to the edge surface, to an area on each of the covers, and to an area on each of the protective sheets. The first protective sheet is wrapped around the unbound edge of the book and is fixed with a pressure sensitive adhesive to the second protective sheet, thereby providing a protective cover for the book. Each of the protective sheets is scored to permit removal of at least part of the protective cover when it is no longer required.

Abstract: A method for manufacturing a book having a security cover comprises the steps of: (a) aligning a stack of sheets to provide an edge surface; (b) locating a first kraft paper sheet adjacent the first sheet of the stack; (c) locating a second kraft paper sheet adjacent the last sheet of the stack; (d) fixing an adhesive binding strip to the sheets along said edge surface and to the outside of the protective sheets; and (e) fixing the first protective sheet to the second protective sheet with an adhesive.
