Joseph Rogers Brown

Died 23 Jul 1876 at age 66 (born 26 Jan 1810).American inventor and manufacturer who made numerous advances in the field of fine measurement and machine-tool production. He perfected and produced a highly accurate linear dividing engine in 1850, and in the succeeding two years he developed a vernier caliper reading to thousandths of an inch and also applied vernier methods to the protractor. Brown's micrometer caliper, widely used in industry, appeared in 1867. He also invented a precision gear cutter in 1855 to produce clock gears, a universal milling machine in 1862, and, perhaps his finest innovation, a universal grinding machine (patented in 1877), in which articles were hardened first and then ground, thereby increasing accuracy and eliminating waste. Cofounded J.R. Brown & Sharpe in 1853.[Image: Brown's universal milling machine]

Hospital Trolley

A beautiful young girl is about to undergo a minor operation. She's laid on a hospital trolley bed with nothing on, except a sheet over her. The nurse pushes the trolley down the corridor towards the operating theatre, where she leaves the girl on the trolley outside, while she goes in to check whether everything is ready. A young man wearing a white coat approaches, lifts the sheet up and starts examining her naked body. He puts the sheet back and then walks away and talks to another man in a white coat. The second man comes over, lifts the sheet and does the same examinations. When a third man does the same thing, but more closely, she grows impatient and says: "All these examinations are fine and appreciated, but when are you going to start the operation?"
The man in the white coat shrugged his shoulders: "I have no idea. We're just painting the corridor."
