Title: Electromagnetic display device
Inventor: KOGLER WOLFGANG
IPC: G09F9/37
Filed: 1999-04-09
Granted: 2007-06-26
Abstract: The invention relates to an electromagnetic display device, comprising a panel which consists of a number of substantially square pixels which are divided into two parts. Each pixel is provided with a rotatably-mounted, bistable tilting flap which is asymmetrical in relation to its rotational axis. Said tilting flap covers one of the two portions of the panel surface in the pixel zone when the flap lies in each of its two stable positions. The side of the tilting flap facing the front side of the panel and the portion of the panel in the pixel zone which is covered by the tilting flap in this position has a first colour and the other side of the tilting flap and the other portion of the panel in the pixel zone has a second colour. A permanent magnet is fitted to the tilting flap in close proximity to the rotational axis. The tilting flap is displaced from a first position into a second position by an electromagnet which is located on the reverse side of the panel and is allocated to the pixels and which has a coil body and a core. The display device panel is connected to a base plate which faces the reverse side of said panel and has at least one opening in one section of each pixel. A pin which is located on the base plate is allocated to each opening and is directed towards said opening. The pin contains a recess on the side facing the panel, in which a light-emitting diode is inserted.

Abstract: A rapid preheat control system, provided in a cooking appliance having an oven cavity, bake and broil elements for heating the oven cavity and a fan for developing an air flow current within the oven cavity, functions to actuate the broil element a higher percentage of time than the bake element during a preheat operation in order to decrease the required time to preheat the oven cavity for a baking operation, while specifically avoiding the need to increase the overall power rating of the cooking appliance. In one preferred embodiment, 100% of the heat emanates from the broil element, while the convection fan is operated either continuously or in a pulsating manner to quickly establish an even heat distribution in the oven cavity. In other embodiments, a portion of the preheat can come from the bake element, but simply in a much lower percentage than the broil element.

Abstract: The present invention relates to an improvement in filtering apparatus including a filter device externally hitched on a wall surface of a aquarium for breeding aquarium fishes. In the outside-type filtering apparatus including a filter device (F) and detachably supported in an externally hitched manner on a wall surface of a aquarium (V), and a water pump (P) for pumping water stored in the aquarium (V), the filter device (F) is formed so that the water pumped from the water pump (P) is divided into a first flow which is returned into the aquarium (V) as remaining unfiltered, and a second flow which is filtered through a filter element and then returned into the aquarium (V) in dependence on a siphon effect. Thus, it is possible to enhance the filtering action provided by the filter element of the filter device and the organically purifying function provided by aerobic microorganisms, and to suppress the clogging of the filter element to reduce the maintenance frequency of the filter element.
