The electric lamp has a glass lamp vessel (1) having seals (3) from which an external metal wire (6) extends. A bare corrosion resistant contact wire (7), having a specific resistance of less than 0.8 .mu..OMEGA.m and a hardness of 50-300 HV is welded, e.g. butt-welded to the external metal wire (6). The contact wire (7) has an axial free end portion (8). An transversally extending intermediate portion (9) may be present between the seal and the free-end portion (8). The lamp allows secure elect...

An electric motor comprises a stator having a plurality of conductive windings radially spaced about a central axis. The motor includes a rotor located radially inward of the stator and rotationally fixed with respect to a shaft disposed along the central axis. The rotor defines an area in which, upon rotation of the rotor, a low pressure vacuum is created drawing air radially outward, with respect to the rotor, from the area. The rotor also includes an annular plate disposed at a transverse end...

An electric vehicle that includes a drive train system that propel the electric vehicle, an electrical system that powers the drive train system, and a steering system that steers the electric vehicle. The electrical system includes a battery charger that is at least one of an off board A.C. charger in which the battery pack is selectively plugged into a socket in the off board A.C. charger by a plug, and wheel generators in which the battery pack is in selective electrical communication therewi...

An electric furnace includes a heating element which is a hollow element made of a lanthanum chromite ceramic having an interior with two open ends in an longitudinal direction, terminal portions at the two ends, and a heat-generating portion between the terminal portions. The terminal portion has a cross-sectional area larger than that of the heat-generating portion on a plane perpendicular to the longitudinal direction. The heating element is provided with high-temperature electrodes and metal...

The application describes an electric motor with a pressure compensation device. This device consists of a BTFE membrane that is arranged in a connecting channel between the interior of the electric motor and the external air. The membrane is arranged in the shield of the electric motor. Since the shield consists of plastic, the membrane can be sprayed on during the manufacture of the shield such that the membrane is inseparably connected to the shield. However, other fastening methods can be co...

An electric lamp according to the invention comprises a lamp vessel (10) which is closed in a gastight manner, which has an end portion (11), and which surrounds a light source (12). The lamp vessel supports a cylindrical collar (30) with an axis (31) at its end portion (11). One or several projections (33a, 33b, 33c) of a first coupling member (30) which each grip into a respective recess (41a, 41c) of a second coupling member (40) couple the collar (30) to a mounting member (40) for fastening ...

An electric fan comprises: a radial impeller for expelling the air trapped therein out of the impeller; a diffuser having a multiplicity of air passages separated by air guides, the air passages adapted to receive the air expelled from the impeller; a fan case for covering the impeller and the air guides; at least one throughhole which is formed in the fan case for each of the air passages; and a silencer equipped with a multiplicity of silencer cavities each having a predetermined volume and co...

A grill for cooking food is provided that has an inclined cooking surface with diagonally positioned ribs projecting therefrom. The ribs have a rounded elongated configuration that all point toward a liquid drain. The ribs have liquid flow channels there between to facilitate liquid flow down the incline into a collection vessel. The cooking surface is surrounded by a retaining wall for holding food in position during a cooking operation.

An electric motor comprises a flange at one end, the corner portions of the flange projecting over the outline of the stator. A ventilator is provided at the opposite end, having outlets which are in alignment with the corner portions. The ventilator does not project over the borderline of the flange.

The invention is directed to an electric toothbrush having a brush section and a drive shaft received in the brush section. The brush section includes a first bristle supporting structure operatively coupled to the shaft for motion about an axis essentially perpendicular to a longitudinal axis of the shaft, and a second bristle supporting structure operatively coupled to the shaft for substantially transverse oscillating motion of the entire second bristle supporting structure relative to the lo...
