In 1928 Smith & Nephew of the UK acquired the licence to market and produce the Elastoplast range of bandages. Beiersdorf bought the brand in 2000. In some countries in Europe Hansaplast, a brand name started by Beiersdorf in 1922, is used instead. [2] A third trademark, named Curitas, is used in parts of Latin America.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...

The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. [1] It was slowly migrated into the 4000B buffered series after about 1975. [ 2 ] It had a much wider supply voltage range than any contemporary logic family (3V to 18V recommended range for "B" series).

The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz). The rotating parts of a turbo generator are subjected to high mechanical stresses because of the high operation speed.
