Abstract: A device for consolidating compositions contained in partially filled dual chamber dispensing cartridges includes a body having a pair of passages, and first and second couplers for connecting the body to first and second dual chamber dispensing cartridges. Once the device is connected to two cartridges, an applicator is connected to one of the cartridges and is used to expel any remaining compositions in such cartridge to chambers of the other cartridge. The contents of several partially empty cartridges can be consolidated in this manner so that a subsequent dispensing operation need not be interrupted to replace cartridges.

Abstract: A lead-free alloy for joining and sealing which is useful as a plumbing solder comprises from 0.08 to 20% by weight of bismuth, from 0.02 to 1.5% by weight of copper, from 0.01 to 1.5% by weight of silver, from 0 to 0.10 percent by weight of phosphorus, from 0 to 0.20% of a rare earth mixture and the balance tin, together with incidental impurities. The alloy has a similar pasty range (i.e. melting temperature and melting range) to the traditional tin-lead plumbing solders.
