Hopper Fields as an Aid to Automation (Design and Application of the Automatic Feed Devices in the Machine Shop) (Machinery's Yellow Back series, No. 39)
68pp booklet with numerous black and white illustrations, in orange textured card covers. 8vo. Covers very lightly rubbed at edges, perhaps a tad faded. A couple of tiny black spots inside front cover, else internally neat, clean, bright and tight. Chapters on General Types of Hopper Feed and Selector Mechanisms; Hopper Feeds for Nuts and Feeds for Bottle Caps; Applications for Hopper Feeds in Production and Inspection etc. Now a very hard to find title, giving valuable insight into the state of automaton in the mid 1960s.
