JCB (company) photography. The logo was designed by Leslie Smith, and is off-set at 18 degrees from the horizontal and 22 degrees from the vertical—the angles Joe Bamford liked. To demonstrate his faith in the hydraulic fail safes on JCB machines (which lock the arms in the event of a loss of hydraulic pressure, preventing them from crashing to the ground), Joe Cyril Bamford arranged to have several backhoes raise themselves up on their arms, and drove his car beneath them. This has since developed into a world-famous demonstration of the versatility of the backhoe configuration. The JCB display team (JCB Dancing
Bamford–Stevens reaction Bamford–Stevens reaction The Bamford–Stevens reaction is a chemical reaction whereby treatment of tosylhydrazones with strong base gives alkenes. It is named for the British chemist William Randall Bamford and the Scottish chemist Thomas Stevens Stevens (1900–2000). The usage of aprotic solvents gives predominantly Z-alkenes, while protic solvent gives a mixture of E- and Z-alkenes. As an alkene-generating transformation, the Bamford–Stevens reaction has broad utility in synthetic methodology and complex molecule synthesis. The treatment of tosylhydrazones with alkyl lithium reagents is called the Shapiro reaction. The first step of the Bamford–Stevens reaction is the formation of the diazo compound 3. In
