Abstract: An automated system for handling concrete pipe and for handling and cleaning the components used in the manufacture of the pipe. Once concrete pipe has cured, the system automatically removes the bell and spigot forming rings from the pipe, and cleans and oils them for reuse. At the ring removal station, the pipe is properly positioned and oriented and the rings are pulled from each end of the pipe and transported to cleaning and oiling stations where all critical surfaces of the rings are cleaned by pulverizing, chiseling and brushing the concrete residue from the rings which are then coated with oil. The automated system is designed to handle rings of different sizes without any intervention by an operator, and the system will handle rings of different diameters that are intermixed.

Abstract: A continuous and automatic process for molding chocolate blocks each having an ornamental relief pattern of one color and a body portion of different color carrying the relief pattern is provided. Also, there is provided apparatus for continuously and automatically producing such ornamental chocolate blocks. A first chocolate material for forming the ornamental relief pattern is cast into a first mold and scraped to scrape off the excess chocolate material. A second mold is then placed on the first mold and a second chocolate material for forming the body portion is cast into through-openings of the second mold. The second chocolate material inevitably oozing into the interface between the first and second molds adheres only onto a rough surface portion formed around and surrounding the through-openings of the second mold without the second chocolate material adhering onto the first mold. It is thus not necessary to remove the oozing chocolate material from the first mold.

Abstract: A method and machine for producing a configurated and specified weight food product in die cavities of a rotary die roll, each of the die cavities being defined by a configurated side wall and a porous bottom wall. During each revolution of the roll a batch of the product is forced into each cavity as the cavities pass beneath a hopper. Upon continued rotation of the roll, the bottom walls of the cavities are moved outwardly so as to force the configurated products from the die cavities. Tempered air at a controlled temperature and at a pressure above that of the atmosphere is directed through the porous bottom walls while the bottom wall is extended so that the configurated product is forced off of the wall and onto a conveyor located beneath the die roll. To facilitate cleaning of the porous dies, the die roll is so constructed that hot water may be directed through the air flow passage during cleaning and the porous bottom wall dies of the drum may be easily removed from the drum without drum disassembly.
