  • Patent number: 5472721
    Abstract: A process and apparatus for grilling and/or reheating a food product by subjecting the product, for an operating time T, to infrared radiation from at least one electrically operated unit for producing infrared radiation, the process comprising: setting a preestablished value for a frequency f; and varying, during at least part of the time T, the electrical supply to the electrically operated unit in a discontinuous manner between a first supply level during a time T1 and a second supply level, different from the first level, during a time T2 in cycles having the preestablished frequency f in order to generate infrared radiation of variable wavelength, wherein 1/f=T1+T2 whereby the product is heated by the infrared radiation.

  • Patent number: 5085136
    Abstract: A toaster having a bread holder (17) mounted to slide vertically in the toaster, has a mechanical device (25) for locking and unlocking the bread holder (17). This device (25) enables the holder (17) to be locked in a low position, and a return spring is provided for raising the holder (17). The mechanical device (25) comprises an upper connecting rod (56) articulated with a lower connecting rod (57) by a common articulation (59), an end of the upper connecting rod (56) opposite the common articulation (59) being articulated at a fixed point (58) and an end of the lower connecting rod (57) opposite the common articulation (59) being articulated with the holder (17). An intermediate lever (42) is articulated with the upper connecting rod (56), and a spring (63) acts on the intermediate lever (42) for retaining the holder (17) in the low position. An end of the intermediate lever (42) comprises a tip (24) which is engageable with a retaining catch (45) when the holder (17) is moved into the low position.
