Abstract: Disclosed are binary azeotrope-like compositions consisting essentially of 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,3,4,4,5,5,5-decafluoropentane (HFC-43-10mee) or nonafluoromethoxybutane. The present invention further includes ternary or quaternary azeotrope-like compositions consisting essentially of 1,1,1,3,3-pentafluorobutane and 1,1,1,2,3,4,4,5,5,5-decafluoropentane or nonafluoromethoxybutane, and additionally trans-1,2-dichloroethylene, n-propyl bromide, acetone, methanol, ethanol or isopropanol.

Abstract: A dispenser apparatus (36) permits dispensing from different model machines sheet material from a standard size supply roll (40), mounted as part of a supply roll member (38) on a support bar (46) having a locator (48a, 48b) which adapts the dispenser apparatus (36) to be mounted on any one of a variety of models of under-stencil wipe fixtures (26). Support bar (46) has a plurality of radial bores (52a-52d) to enable positioning supply roll member (38) at a selected longitudinal position in support bar (46) to permit aligning the supply roll (40) with a given cut-out pattern (18) on stencil (16). Supply roll member (38) comprises a supply roll (40) mounted on a core member (42) having a core member extension (42a) which protrudes beyond supply roll (40) and has a radial bore (42b) for mounting supply roll member (38) on support bar (46) by screw fastener(54).

Abstract: A nozzle (10) which is mountable on conventional aerosol dispensing valves comprises an electrically conductive extension tube (18) situated to receive discharge from the outlet of an aerosol product dispenser. The nozzle also includes an actuation member (28) which is electrically connected to the extension tube (18) and which is dimensioned and configured so that the user can dispense aerosol product by depressing the actuation member (28). Optionally, the extension tube (18) comprises a detachable discharge region (24) to allow the use of a variety of differently configured tube outlets.
