  • Electrical cooking unit and electrical cooking apparatus provided with this unit
    Patent number: 5021636
    Abstract: The electrical cooking unit has a housing (1) accommodating an electrical IR lamp (10). The lamp (10) has a lamp vessel (11) which is bent according to an n-gon with several bent portions (14) interconnected by straight portions (15). End portions (12) of the lamp vessel (11) are passed through openings (4) in the side walls (3) of the housing (1) to the exterior.

  • Electrodeless low-pressure gas discharge lamp
    Patent number: 4645967
    Abstract: An electrodeless low-pressure gas discharge lamp includes a glass lamp vessel (1) which is provided with a sealing member (6) connected to the wall of the lamp vessel by means of a suitable sealing material, and which has on its inner wall a conductive layer (7), at least part of which is transparent, that extends beyond the connection to the sealing member (6), the member being slightly recessed into the lamp vessel. The inner conductive layer can thus be connected in a simple manner to an electrical conductor, which during operation of the lamp is connected, for example, to one of the supply wires of the mains.

  • High pressure discharge lamp
    Patent number: 4642520
    Abstract: High-pressure discharge lamps generating UV radiation are provided with an internal safety switch, that interrupts the current circuit through the lamp upon fracture of the outer lamp envelope. In lamps according to the invention the safety switch is a member of a material selected from the group consisting of zirconium-aluminum alloys, sintered zirconium powder and sintered mixtures of zirconium powder and nickel powder.

  • High-pressure discharge lamp
    Patent number: 4380714
    Abstract: An oxidation-sensitive element electrically connected in series with the discharge vessel of a high-pressure discharge lamp extinguishes the lamp when the element, upon fracture of the outer envelope of the lamp, is oxidized and prevents damage as a result of emission of UV radiation.In a high-pressure discharge lamp according to the invention, the oxidation-sensitive element (7) consists of an electric insulator (20) on which two spaced conductors (21, 22) are provided which are interconnected electrically by a vapor-deposited layer (23) of an oxygen-gettering metallic, evaporating getter. Opposite to the insulator (20) is present a holder (8) from which the getter was previously evaporated on to the insulator.
