Patent DE-3942732-A1 (DE)
Inventor: MOHRING FRITZ
IPC: B60H1/22
Filed: 1989-12-22
Abstract: A motor vehicle storage heater comprises a heat-exchanger (8) which is lodged in an outer housing (12). The heat-exchanger divides the hot-gas chamber (4), which is connected to the combustion chamber, from a heating medium channel (10) formed by the wall (8) of the heat-exchanger, the outer housing (2) and ribs (14) on the wall (8) of the heat-exchanger. In the event of malfunctioning, e.g., failure of the heating medium to circulate, the outer surface (F) of the heat-exchanger (8) heats up. A temperature sensor (201) lodged in the outer housing (12), which has a contact head (16) that touches the wall (8) of the heat-exchanger, shuts down the electrical system of the storage heater, and hence the storage heater itself, in the event of overheating. To ensure good contact between the contact head (16) and the wall of the heat-exchanger, even if the heat-exchanger (8) is unavoidably deformed, the temperature-monitoring element (201), which is designed, for example, as a safety fuse or an overheating switch, is slidingly mounted in the outer housing and pretensioned against the outer surface (F) of the wall (8) of the heat-exchanger.

Title: Digital correction of movement in static scintigrams - using gamma camera for static acquisition to lessen movement blurring structures
Inventor: BOCKISCH MARIANNE
IPC: G06T5/50
Filed: 1990-01-23
Abstract: A process is described for the assimilation of static scintigrams that have been corrected in respect of their movement.  This requires a gamma camera, to which a digital input computer is attached, whose operational storage records at least 2 to 4 pictures with the desired resoltuion of the definitive scintigram.  Static scintigrams are accumulated sequentially in many short chronological intervals subdivided into one or several intermediate data stores. At the end of the relevant chronological interval the picture from these stores or store is added to the total picture gathered from all intermediate pictures that have been added up to that time so that the focal points of the intermediate and total picture coincide. With this, physiological movement in an organ under examination, as well as undesurable shifts in the patient are compared. USE/ADVANTAGE - Improves resolution of static scintigrams.  Reduces image distortion caused by movement in liver and osseous thorax.
