Title: Liquid sprayer

Filed: 1972-09-22
Abstract: 1389702 Liquid spraying devices THIOKOL CORP 22 Sept 1972 [14 Feb 1972] 44029/72 Heading F1A A liquid sprayer 10 comprises a liquid container 11 on which is rotatably mounted a spray cap 13, relative rotation between container 11 and tap 13 serving to charge a pressure chamber 33 from which liquid can be discharged through a spray nozzle 19 by depressing a button 24. Container 11  comprises a fitting 42 for filling of the container with a removable plug 41 therein, a one way air inlet valve 44, a one-way valve 43 for permitting liquid flow from the container 11 to chamber 33, and a conduit 32 for conducting liquid to chamber 33. Cap 13 has a piston 9 slidably, but non-rotatably, mounted therein, a central part of the piston entering chamber 33 and cam members 29 thereof co-operating with cam recesses 30 in container 11 such that, upon rotation of cap 13 relative to container 11, cam members 29 ride up cam recesses 30, thus moving piston 9 away from container 11. Passages 38, 16 serve to lead liquid from chamber 33, via a valve 17 operated by button 24, to the nozzle 19. A spring 15 tends to urge piston 9 towards container 11. In use, the container is rotated relative to cap 13, the piston 9 thus being forced away from container 11 by the cam action so that liquid is sucked from container 11 into chamber 33. The chamber 33 is thus charged, flow back into container 11 being prevented by valve 43. Depression of button 24 pushes down valve member 20 so that an orifice 8 thereof, normally closed by seal 21, communicates with the charged chamber 33 and, due to the spring load on piston 9, said piston is forced down thus forcing liquid up passages 38, 16, through valve 17 and out through nozzle 19.

Apparatus for density gradient electro-phoresis comprises a vertically positioned tube of electrical insulating material for receiving density gradient liquid, means including a reversible pump for pumping a displacing liquid into and out of the tube through the lower end thereof to vary the position of the density gradient liquid within the tube, and means establishing an electric field across axially-spaced points within the tube comprising electrodes connected to a source of D.C. voltage and immersed in buffer solutions contained in chambers having communication with the tube at the axially spaced points through openings covered by semi-permeable membranes. In the embodiment shown the tube for containing the density gradient liquid comprises tubes 11, 11' positioned end to end and separated by a quartz ring 21 at opposite sides of which are positioned a lamp 16 and photo-cell 24, respectively, forming a photo-metric scanning system. By pumping displacing liquid into and out from the tube via fitting 67 the fractionated zones of the sample may be passed by said scanning system and the light absorption, and hence the concentration of the fractionated zones, may be measured, which scanning process may be repeated as often as desired. The upper end of the tube 11 abuts a tube 27 having appertures 38 covered by semipermeable membranes, which appertures connect with chambers 31 and hence with trough 34, the chambers 31 and trough 34 containing a buffer salt solution wherein is positioned an electrode 36. Similarly the lower end of the tube 11' abuts tube 47 having apertures 51, covered by semipermeable membranes, contacting openings 52 and 53, an inner trough 56 and an outer trough 60, the openings 52, 53 and the troughs 56, 60 containing a buffer salt solution, the troughs being inter-connected via openings 57 covered by semi-permeable membranes 58, and the outer trough containing a counter-electrode 46. The tubes 27, 11, 11' and 47 are contained within the concentric tubes 40, 44, 64 which provide a cooling jacket, cooling fluid being passed therethrough between hose nipples 42 and 65, the cooling jacket spaces being inter-connected by passages 45 and 66. The density gradient fluid may be passed into the tube via the lower opening 67 or may be pipetted therein via the upper opening 43.
