    摘要： A liquid jet gas pump (10) providing suction to recover vapor through a line (25) connected to dispensing nozzle (27), the pump having chambers (32, 34) for collecting liquid carried by returning vapor and a float (82) therein so that the float, when the amount of liquid collected in the chambers becomes too great, blocks the suction path through the pump thereby shutting off the dispensing nozzle (27). The pump (10) also has an internal connection (92) from a diaphragm chamber (90) to an internal area (33) which is substantially at atmospheric pressure during pump operation thereby eliminating the need for an access vent from the diaphragm chamber (90) to the atmosphere.

    摘要： It is discovered that a liquid dispersion of polymer powder particles, predominantly of polyvinylidene fluoride, simultaneously: (a) can suspend electrical property additives, such as crystalline, hard, dense particles of generally spherical shape, uniformly in desired concentrations; (b) while containing a useful concentration of any of a wide range of such particles, can be deposited by high shear transfer to a substrate in accurately controllable thickness and contour; (c) when so deposited can be fused into a continuous uniform film which has low absorptivity, e.g., of moisture, and acts as a barrier film; (d) where desired, can, as one layer, be fused with other such layers, containing other electrical property additives, to form a monolithic electrical component; and, (e) in general, can meet all requirements for the making of any useful electrical circuit components, including electroluminescent lamps, by printing and coating techniques with a high degree of accuracy and controllability.
