Abstract: The invention discloses a novel type of bag threading device to be used in an automatic bag loading apparatus for rotary bagging machines, and substantially comprises a stationary vertical support frame (10) holding a swinging arm (12) bearing at the other end the pincers (13) associated with a system of connecting rod (14) and crank (19) having the function of rotating the pincers (13) in order to position them in the picking phase axially aligned with the bag (3) to be picked and subsequently with the nozzle (2) of the bagging machine, said arm being able to carry out an angular displacement between to bag positioning device (6) and the nozzle (2) of the rotary bagging machine (1) to be fed in that moment, effected by a cam (15) in order to carry out its angular displacement, acting on a roller (17) arranged on said swinging arm (12), the cam (15) being rotated around its shaft by a motor with reduction unit, the cam shaft and that of the bagging machine being rotated in a synchronous way through known mean

Abstract: A bag placer apparatus having a number of improvements which, in combination, significantly increase the rate of placing valve bags upon a plurality of filling spouts to fill the bags with a flowable material. The apparatus comprises a pair of magazine apparatus for stacking the bags, a transfer apparatus for removing one bag at a time from the stack, a presenter apparatus for aligning the bag with the valve portion thereof in a precise location, and a picker-spouter apparatus which picks up the aligned bag, opens the valve and places it upon any one of one, two or three filling spouts. Each magazine supports a plurality of vertical stacks of horizontally positioned bags. The transfer apparatus alternatively de-stacks one bag at a time from each magazine and transfers it laterally to the presenter apparatus. The presenter apparatus includes means including a novel tilt arm for automatically transfering and registering each bag in precise position and alignment relative to the picker-spouter apparatus.

Abstract: In an apparatus for preserving different kinds of reagents to be selectively delivered for performing different test items in an automatic chemical analyzer, the reagents are contained in respective vessels which are placed on a turntable rotatably arranged in a compartment inside of which is kept at a low temperature, beside each reagent container is movably arranged a plug plate having an elastic plug secured thereto and a movable lever is arranged to engage with any one of the plug plate so as to remove the plug out of an opening of the reagent vessel only when a probe of a delivery device is moved through the opening.

Abstract: A method of discharging material from a rotary furnace is disclosed, which method comprises the steps of feeding the material from a preheater into the rotary furnace under gastight conditions, subjecting the material to heat treatment within the rotary furnace, connecting the inlet port of a container to the discharge opening of the rotary furnace, discharging the material from the rotary furnace while maintaining gastight conditions, and thereafter detaching the container from the rotary furnace.

Abstract: An apparatus for aseptically filling premanufactured, presterilized, flexible containers, connected in a continuous web, includes a chamber with an inlet mouth for receiving empty containers seriatim, and an outlet mouth for dispensing filled containers seriatim. The inlet and outlet mouths have respective seals for sealing to the surface of the containers to prevent entry of contaminants into the chamber. This chamber is partitioned to form a spraying compartment, adjacent to the inlet mouth, and a filling compartment, adjacent to the outlet mouth, with a drying compartment therebetween. A sterilizing agent is continuously sprayed, as a mist, into the spraying compartment to coat the exterior of the containers with the sterilizing agent as they are serially advanced through the chamber. This mist also provides an aseptic barrier between the inlet mouth and the drying compartment.
