...that two musicians were responsible for the invention of color print film? Fascinated by photography, Leopold Godowsky and Leopold Mannes worked together to produce an easy-to-use, practical color film. They worked full time as music teachers and gave concerts while experimenting during their off hours in Mannes' kitchen. Their success earned them full-time, well-paying jobs at Kodak and their efforts resulted in Kodachrome film, which was introduced in 1935.

AbstractDisclosed is a process which produces precision ground articles such as tungsten carbide burs without the use of skilled craftsmen. An automatic apparatus is described which is capable of performing the motions necessary to produce a machined given object and includes a control system for automated bur grinding. The process also converts geometric bur definitions into instructions that will produce the proper actions by the automated grinding. | InventorsAssigneeApplicationNo. 06/556157 filed on 11/29/1983US Classes:451/5, Computer controlled451/140, Work rotating451/141, Helical blade451/48, Drill, thread, thread cutter, reamer, or rotary cutter abrading451/6, By optical sensor700/164, Grinding700/182, Including CAD, CAM, or CIM technique700/185Prompting techniqueExaminersPrimary: Whitehead, Harold D.Attorney, Agent or FirmUS Patent References3851563, 4064657, Machine for machining spiral cutting edges on cutting toolsIssued on: 12/27/1977 Inventor: Habib4115956, Programmably controlled machine for grinding end cutting tools and the like Issued on: 09/26/1978 Inventor: Huffman4136390, Grinding control system for forming non-circular punching tools Issued on: 01/23/1979 Inventor: Farrell , et al.4163345, Arrangement for the grinding of rotary profile cutters Issued on: 08/07/1979 Inventor: Meili4461121Program-controlled grinding machine, particularly for sharpening of rotatable cutting tools Issued on: 07/24/1984 Inventor: Motzer , et al.
