E., 39, Melrose Road, Birchfield, all in Birmingham. Dec. 10, 1932, No. 35047. [Class 49.] Pasteurizing apparatus for treating liquids in bottles or other containers consists of a tank 8 having a common feeding and delivery point, regularly spaced charges of the containers being carried through the tank on a rotating table beneath a plurality of dripping devices 23, the lower portion of the tank being divided into two parts A, B from one A of which water is supplied to feeders for variable temperature zones and from the other part B to feeders for a constant and maximum temperature zone and to the feeders for the variable temperature zones, and mixing valves 28 for controlling the mixing of water from the two parts to obtain the required temperature in the water to be fed to the variable - temperature zones. The tank 8 is supported on adjustable feet 9 and divided into the sections A, B, by an upwardly pressed portion 8<a> of the bottom. The bottles are disposed on perforated trays 17 which are inserted in turn on a roller conveyer 18 which takes them into the apparatus in which they are supported on the rotatable circular table which is formed of ribs 12 attached to a boss 11 rotatably mounted on a column 10 and having supporting rollers 14 which run on a circular track 15 fixed to the vertical wall of the tank. The frame is rotated step by step by a handle 32 through gearing and a sprocket chain. At each step a tray of treated bottles is removed and replaced by a tray of untreated bottles, the ribs 12 having rollers 16 on which the trays run. Within the tank the trays pass through sprays of water from perforated drip trays 23, the temperature of the sprays increasing to the constant temperature zone B and then diminishing up to the discharge point. Water is supplied to the trays 23 by two pumps 19, 24, one 24 of which takes hot water from zone B in which it is maintained at constant temperature by a steam coil 25 and feeds it through pipes 27, 27b to the trays over that zone and also where required through mixing valves 28 to the trays above the other zone A to which trays water is also supplied through pipes 20, 20<a>, 21, from the zone A by the pump 19. A cold water supply is provided for the last drip tray before the discharge point.
