Abstract 837,720. Siphons. TECHNICON CHROMATOGRAPHY CORPORATION. June 6, 1958, No. 18202/58. Class 69 (1). Liquid measuring and delivery apparatus for automatically discharging a predetermined quantity of liquid from a supply receptacle 10 comprises a siphon tube 12 having its up leg 18 provided at its inlet portion with an integral joint element 22 adapted to be releasably connected by a spring clamp 24 to a companion joint element 16 at the outlet of the supply receptacle 10 for movement about : horizontal axis A-A for predetermining the discharge operation of the siphon in accordance with the liquid level in the receptacle 10. The down leg of the siphon comprises an upper part 28 terminating in a socket portion 30, in movable fluid-tight relation with a lower discharge portion 34 of the down leg so that adjustment of the siphon can be made without displacement of the discharge portion from an upright vertical position. In a modification shown in Fig. 4, the joint in the down-leg is omitted. Specification 689,079 is referred to.
