Title: Sorter for large dish washer unit - uses weight of items in circulating water flow to determine separation
Inventor: KERN RAINER
IPC: B07C99/00
Filed: 1975-10-23
Abstract: Large scale industrial dish washing unit includes a sorting system for the cutlery dishes and waste. The articles to be separated from each other are tipped by a supply chute into a water bath in which they pass into a further chute which is formed by baffle plates. Circulating water flows up out of this chute at a speed which is faster than the rate at which the dishes fall, but slower than the rate of fall of the metallic cutlery items so that these heavy and light items are separated on one side above and on the other below the chute. The metal cutlery items fall down through the chute onto a cutlery conveyor belt which takes the cutlery out of the bath. The lighted crockery items which are still heavier than water, are passed up over the crest baffle plate towards the intake point of the circulating pump. The waste floats on top of the water and is drawn by the water flow to a filter plate where it can be removed.

Title: Waste compactor with hydraulic precompression - performs precompression and main compression in same cycle which is initiated by proximity switch
Inventor: BERGMANN HEINZ
IPC: B30B9/30
Filed: 1976-03-18
Abstract: A waste compactor (1) has flaps which accept the waste in the open position. They close hydraulically and precompress the waste. The compression piston moves upwards under hydraulic power and moves the precompressed material in the direction of the container opening and thus effects a further precompression. The pressure piston moves hydraulically downwards and effects the main compression at the precompressed material. With the aid of the compression piston, it then delivers the intensely compressed waste into the container. Specifically, the waste compacter compresses bulk material up to one thirty sixth of its initial volume while the pre- and main compression are effected after each other and in one work cycle in the waste compactor. More specifically, the waste is filled into an opening at 1200mm. x 1200mm. An electronic proximity switch automatically switches on the hydraulic system at a given filled level and the system starts it work cycle.
