Abstract: 1435374 Discharging liquids by gaseous pressure MICROMEDIC SYSTEMS Inc 25 April 1973 [1 May 1972] 19565/73 Heading F1R [Also in Division G1] Liquid is transferred from a vessel 18 through a dip tube 22 by applying air-pressure to the vessel through an opening 82 so that the flow of air passes over the dip tube to clean it. Air is supplied to a chamber 78 in a head 54 and through which the tube 22 passes and flows to the opening 82 and also to an opening 74. The vessel 18 is mounted on a guide which is raised to cause the mouth of the vessel to seat on a seal 62 in the head 54. Further raising causes the mouth of the opening 74 to engage a seal 72 on a plate 70 and the dip tube to enter the vessel. The quantity of liquid discharged may be controlled by a solenoid actuated valve (26) Fig. 6 (not shown) controlled by a timing device (108) started when a rise in pressure in the vessel due to closing of the opening 74 is detected. In a modification, Fig. 5, a crank mechanism 146 operates a slide 142 round which the dip tube 152 is looped so that the tube is inserted into the vessel 120 in a separate operation. As described the apparatus comprises pairs of vessels and duplicate discharge arrangements.
