Abstract: Disclosed are a process of and an apparatus for producing paper webs coated on both sides, in particular so-called LWC-papers, in a paper making machine. Firstly, one side of the paper web (1) is coated in a first coating station (8) and then dried. Subsequently, the other side of the paper web (1) is coated in a second coating station (25) and then dried. Each coating station (8, 25) includes an application role (10), an opposing roll (11) and an application unit (13) arranged on the application roll for indirectly coating the paper web. The metering of the coating mass on the application roll (10) takes place by means of a smooth roll doctor. The coated paper web (1) is calendered by means of an on-line calendering unit (60).

Abstract: An appliance switch for an electric shaver is equipped with a safety device guarding against accidental operation, which device is slidable coplanar with the appliance switch, is arranged in a housing and is equipped with positive engagement members which are adapted to be slipped over a latch member of the appliance switch and prevent the latch member from being movable out of its locking position. In this manner, a reliable safeguard is provided preventing accidental operation of the shaver.

Abstract: A cordless portable hand held hair dressing appliance has a housing provided with a pistol-grip handle and containing a battery operated electric fan arranged to draw air into the housing through an air inlet for flow through a heat structure to be heated prior to discharge from a housing air outlet. The heater structure includes air elongated heat accumulator member of high specific heat penetrated in the longitudinal direction by a plurality of air ducts each having an intake communicating with the housing inlet and an outlet communicating with a mixing chamber connected to the housing outlet. The heat accumulator member is formed of a ceramic, e.g., Al.sub.2 O.sub.3 and MgO, and is adapted to be heated to store heat therein by an electrical heating conductor structure formed by a layer of electrical resistance material on the wall of each duct.
