Sleeve couplings are also known as box Couplings. The coupling terms are called vibronic couplings. Commonly keyed components include gears, pulleys, couplings, and washers. It also used homokinetic shafts instead of rubber couplings. The mine damaged the fuel tank, propeller shaft couplings, and fire control equipment. Gear couplings and universal joints are used in similar applications. The different styles of hose couplings have influenced fireground tactics. His patents from 1905 covered both fluid couplings and torque converters. Many driveline upgrades were incorporated due to previous failures in the couplings. Peak splittings due to J- or dipolar couplings between nuclei are also useful. The 1920s saw some vehicles fitted with automatic couplings and steel bodies. Notable differences include voltages, loading gauge, couplings, signalling and control systems. The Standard Model generates fermion masses through their couplings to the Higgs boson. There are two basic approaches available for dealing with mutual couplings and active components. European modellers tend to use scale hook and chain couplings.
