Abstract: A bag-on-valve aerosol valve system in acontainer. Propellant is pressure filled around the valve stem, outwardly over the stem gasket and down into the container space outside the bag. Product is filled through the valve stem into the bag. The valve stem has an exterior intermediate frusto~-conical annular surface and the valve housing has an interior frusto-conical annular surface, with both surfaces engaging in annular sealing contact to block propellant access to the bag when the valve stem is deeply depressed to a first predetermined position for propellant pressure filling. A stem exterior surface indent interacts with radially-biased spring-loaded slides to lock the stem in a second less depressed predetermined position for product filling through the stem down into the bag. The propellant and product may be pressure filled in either order using essentially conventional pressure filing equipment, after the valve is mounted on the container and the bag is mounted on the valve.

The foamed films of the present invention are thin (generally from about I to 10 mils thick), and have an MD tear strength of a t least about 160 grams for a 3 mil film as measured by ASTM D 1922. The foame d films of the present invention are preferably made at least in part from blends which comprise from 10 to 95 percent by weight of LLDPE having a relatively high (1.5 to 6) MI and from 5 to 90 percent of an LDPE resin havi ng a relatively low MI (0.5 to 2.0).

Title: Process for chemical etching of parts fabricated by sterolithography
Inventor: LUAN BENLI
IPC: G03F7/32
Filed: 2006-02-28
Abstract: A process for chemically etching a stereolithography resin involves chemically etching a shaped object of the resin at a temperature in a range of from about 20°C to about 30°C for a time of from about 30 seconds to about 60 seconds with a saturated aqueous solution of permanganate, for example potassium permanganate. The process is faster, simpler and uses less environmentally harmful chemicals than previous etching processes for SLA parts. Etching is also more thorough and can reach hard to access places that sand blasting cannot. The etching process may be part of a process for metallization of a rapid prototyping part fabricated by stereolithography. Excellent etch coverage leads excellent coverage by the coating metal and to stronger metal layers.
