  • Patent number: 4105493
    Abstract: The invention concerns a method for producing foils for dry shavers.The method of the invention includes forming a layer of photosensitive material on each side of a metal plate, exposing each side to light to produce a pattern of exposed and unexposed areas, corresponding to perforations at one side and recesses in the backs of the bars of the foil on the other side, etching each side, them removing photosensitive material from the front side and carrying out further etching until the foil is completely perforated.The invention is especially suitable for forming foils for battery operated dry shavers.

  • Patent number: 4100397
    Abstract: An electrical heater assembly comprising a heat generating element and a temperature regulating device supported by a heat conducting core of electrically insulating material is constructed to provide a thermal path for conducting heat from the heat generating means to the temperature regulating device with minimum thermal resistance, whereby temperature fluctuation is minimized. The temperature regulating device is substantially encircled by terminal means electrically coupling the temperature regulating device in circuit with the heat generating element. The temperature regulating means is disposed substantially entirely within a cavity in the core so that substantially all of the outer peripheral surface of the terminal means is in friction contact with the surface of the cavity.
