Abstract: The present invention relates to an apparatus for toasting of bread etc. comprising a housing (2) with a slot (3) which issues into a toasting space (4) into which products to be toasted can be introduced, while heater elements (5) are arranged on both sides of this space (4) which each cooperate with a reflector (7) for reflecting radiation in the direction of the toasting space (4), and the housing (2) is made at least partly of a transparent material. In order to obtain an evenly distributed browning and a good view of the products in the toasting space (4), the reflectors (7) cover the whole area of the toasting space (4) and are made of a transparent material.

Abstract: An apparatus for toasting bread, includes a housing (2) with a slot (3) which leads into a toasting space (4). Heater elements (5) are arranged on both sides of this space which each cooperate with a reflector (7) for reflecting radiation in the direction of the toasting space. Grille elements (8) are located to center the bread in the toasting space. A bread support element (9) is provided for moving the bread up or down. The grille elements (8) and the support element (9) are moveable in a coordinated way. The grille elements (8) and/or the heater elements (5) are arranged on two pairs of arms (6) which are hinged (14) to a base part (1), while the support element (9) cooperates with a lever (19) which is also hinged (18) to the base part (1), the arms (6) and the lever (19) cooperating with openings (17) in a slide (10) which is movable in the base part (1).

Abstract: A hot-gas engine in which the supply of fuel to the burner device is controlled by means of a control signal which is derived from a differential pressure signal which represents the volume flow of combustion air and which is corrected for variations in temperature and pressure of the ambient air.

Abstract: A rotary heat-exchanger comprising a control device which is controlled by the variable pressure of one of the two hot and cold gas flows, the control device exerting a force on the rotor which force is proportional to the resultant gas flow pressure, in order to maintain a fixed axial position of the rotor with respect to the rotor housing.

Abstract: An engine including a combustion chamber having connected thereto a combustion-air inlet duct in which a first restriction is incorporated, and a flue-gas return duct incorporating a second restriction connected to a part of the combustion air duct which is situated between the combustion chamber and the first restriction.
