There is disclosed an article treating apparatus particularly apparatus for pressure-impregnating or vacuum impregnating porous articles such as metal castings. A holder for the articles or a metal basket containing them is disposed in an autoclave and can be rotated about a horizontal axis. It has a horizontal through-passageway so that articles to be treated can be simultaneously loaded at one end of the passageway and unloaded at the other end of the passageway by an indexing mechanism. The indexing mechanism has a plurality of pusher arms which can be moved laterally into the path of the articles and then moved horizontally to push the articles along rails into and out of the passageway. The holder is stopped at a predetermined rotary position in which a longitudinal slot is opposite the pusher arms so that unloading and loading may be effected simultaneously with a single movement of the indexing mechanism, a pusher arm passing completely through the slot. The lower part of the pressure vessel contains liquid impregnant and the holder can be rocked between an upper loading and unloading (and spin) position and a lower immersed position.
The invention relates to a rotary drum structure for a sterilizer. The structure includes: four beams (30, 32, 34, 36) disposed parallel to said axis and defining a rectangular parallelepiped volume; a plurality of spacer elements (52, 54, 56) disposed in the four faces defining said parallelepiped volume and forming triangulated structures; a second end part (60) fixed to second ends of the beams to define an inlet opening (64) into said drum; and a circular running path (62).
A machine for packaging is a non-germ atmosphere according to the present invention comprises a container sterilization means which sterilizes containers, and a fill-end-pack means which fills the food in the containers and seals them with lids. At least a pair of rails runs through the container sterilization means and the fill-and-pack means. The containers are hung by the rails and they are intermittently carried by a first intermittent carrying means and the container sterilization means and by a second intermittent carrying means in the fill-and-pack means. The machine is arranged such that it is readily adjustable for different sized containers without allowing germs in the atmosphere to enter into the machine. The container sterilization means for further comprises an air current control means to control the flow of the sterilization agent and to fully sterilize the containers.
A transmission assembly capable of driving a dishwasher conveyor at different speeds to accommodate different needs, without requiring a multiple speed motor. Moreover, speed adjustments can be made without stopping the conveyor and without any risk of damage to the motor. Adjustments are effected by varying the radial distance between a driven member and an axis about which the drive assembly pivots. A detent arrangement provides a positive indication that the speed is set at a particular setting corresponding to a particular radial distance.
A machine for impregnating a die cast metal part with liquid impregnant comprises an impregnation chamber having liquid impregnant in a lower portion, an opening for ingress and egress of the parts being defined in a side wall of the chamber above the liquid impregnant, a door for sealing the opening, a part holder in the chamber and an elevator for positioning parts above the liquid impregnant during evacuation of the chamber and then immersing the parts in the liquid impregnant during subsequent pressurization of the chamber.
