ne object ofthe invention is .to insure 125 the'unifoim treatment of all portions of the' liquid as 1t' passes through the apparatus. Another object of the invention. is to produce apparatus adapted to be used in pasteurizing and comprising in combination a., series of liquid holders, a valve mechanism' operating to successively lill sucliholders, to empty the holders and to transfer a portion of -the liquid yof one holder for the einptying thereof to another holder.; and
procedure consisting in filling and emptying .liquid holders in a series progressively, and
transferring a portion of the liquid'in a filled holder to 'an empty holder. and more 40 specifically in making such transfer prior lto the filling of the latter holder.
'Another object of the invention is to provide, in apparatus of this character,l a bypass or liquid connection, whereby a porportions ofthe liquid delivered by the valve to each holder may he conducted 'ito another "holderf Anothervobject of the invention is to pro'- vide, in' apparatus of this character, a va'lve of which is formed vwith a by-pass to couductliquid from one conduit or liquid connection to an other conduit or liquid connection.'

The lower end of the pipe section 21 rotatably lits into an opening formed in a coupling of the ports of the ducts 14", 11. successively-l wit-h the openings 15. During the time that the port of the duct 14. is in registry with theralvc opening 15n 'for a holder or' vessel 9, as the' valv'e member 14" rotates,
liquid .will flow -from the chamber. 1'2. through the duct l-l" to the holder 9 to fill the same, the speed of the valve member ll'f -and` the size of the openings 149,15, heilig' `s1iigoliortined so that during. the registry' thereof suiicient liquid will flow through the valve elements to substantially fill the holder the ,rotary movement of the valve member 14: -until the.' receiving port of the discharge duct 14 registers with the opening 1 5?,-
whereupon the liquid will flow hygravity fromlthe holder through the valve opening lc'and duct 14 to the discharge vpipeor conduit 20. As the .ducts i4", 11, and the' id oo valve, ports thereof are of substantiallythe I same size, and the valve member 14" rotates-A unifoi-mly, it will b e undeistoodtlnit sub-4 stantially the same quantity of liquid may fion' ont of each holder as flowed into' it iii the same time interval. As the holders 9 are arranged around the valve seat member 15 and each-'is connected tol the adjacent port i 15", provision-is made for filling' and emptying the holders progressively.
The receivingport of'th'e outlet duct 14.
of the valve mechanism 1 4 may be arranged I at any predettamined point angularly of the axis of the i'alveunen'iber 14' relative to the discharge port of theinlet duct 14" so that the distance of` travel voli-the valve'meinber Hf from "'theposition for'filling to the po sition for emptying may'be of proper length.
