Abstract: An electric lamp including a light source, a lamp cap having a shell and a base, a housing connected to the light source and to the lamp cap, and a ballast which is electrically connected to the light source for operating the light source and which is arranged at least partly in a space surrounded by the housing and the lamp cap. The lamp cap includes contacts electrically connected to the ballast at least during lamp operation, one of said contacts being provided on the base and a further one on the shell. The further contact is formed by a band of conducting material around the lamp cap, which band directly adjoins the base at one side and adjoins a band of insulating material around the lamp cap at another side. This suppresses the interference generated in the supply mains, due to capacitive coupling between the ballast and the further contact, to a considerable degree.

Abstract: Low-pressure mercury vapor discharge lamp having a discharge vessel sealed in a gas-tight manner and filled with mercury and a rare gas. The discharge vessel comprises four parallel extending straight tubular portions positioned in a square which are connected together by means of coupling joints to form a discharge passage. Two electrodes arranged at the ends of two tubular portions (4, 6) and are positioned side-by-side on one end of the discharge vessel. A discharge arc is maintained between the two electrodes through the discharge passage during lamp operation. A supporting member the four outer walls of the tube parts located between the four table parts engages the four outer walls of the tube parts near the ends of the tube parts remote from the electrodes.

Abstract: There is provided a shaving apparatus comprising an external cutting element and an internal cutting element cooperating with and drivable relative to the external cutting element with a reciprocating movement. The internal cutting element is secured to the external cutting element by means of a connecting element which is flexible in the direction of driving and is rigid in directions extending substantially transversely of the direction of driving. The external cutting element is formed as a U-shaped part from a sheet material. The internal cutting element together with the connecting element constitutes a strip also made of a sheet material and positioned between the legs of the U-shaped part. The internal cutting element is situated at the end of the strip near the transverse portion of the U-shaped part; and the other end of the strip is connected to the legs of the U-shaped part.

Abstract: There is provided an epilation apparatus comprising a drivable member having a hair-gripping wall, and a stationary complementary member having a confronting wall spaced from the hair-gripping wall of the drivable member to provide a hair gap therebetween.
