Title: Centrifugal-force switch for limiting or switching-off an internal-combustion engine
Inventor: STIPEK THEODOR DIPL ING DR
IPC: H01H35/10
Filed: 1982-09-03
Abstract: A centrifugal-force switch for limiting or switching-off an internal-combustion engine has, on or in a shaft (1), a flyweight (3) which is guided such that it can move in the radial direction and is held, originating from its inner position, over a first subregion of its full lifting movement under a smaller spring pretension than in the second subregion of its full lifting movement. When the full lifing movement takes place, the flyweight (3) operates an electrical switch (16) when said flyweight reaches its outer position. Such a spring characteristic can be achieved using two springs (7, 8) of different spring force, the spring (7) having the smaller spring force engaging on the flyweight (3) over the full lifting movement, and the spring (8) having the larger spring force not engaging with said flyweight (3) until the first subregion of the full lifting movement of the flyweight (3) has been completed. <IMAGE>

Patent DE-3244188-A1 (DE)
Title: Warning device for monitoring windows and doors on buildings
Inventor: MAGER THEO DIPL ING
IPC: G08B21/18
Filed: 1982-11-30
Abstract: For monitoring windows and doors, proximity switches mounted at a particular distance above one another are activated by metal angles or magnets in the door frame or window frame, in such a way that, with the windows or doors tilted for ventilation purposes, after an adjustable time interval corresponding electronics trigger an attenuated acoustic signal which acts as a reminder to close them (ventilation monitoring). The device is changed over by displacing the housing top part of the electronics, so that both windows or doors tilted for ventilation purposes, as well as closed elements, are monitored, in that improper opening triggers a non-attenuated acoustic signal (break-in monitoring). These functions are initiated by the proximity switches mounted one above the other. Thus, the proximity switch mounted at the top, at a particular distance from the tilt axis, is responsible for ventilation monitoring, whilst the proximity switch mounted at the bottom, as near as possible to the tilt axis, is responsible for the break-in monitoring. The size and shape of the warning device are such that it can receive the electronic part and the proximity switches at the necessary mutual distance and can be mounted directly on frames or cases.

Title: Avalanche self-protection device
Inventor: KOELSCH MICHAEL
IPC: A62B99/00
Filed: 1983-01-12
Abstract: A compressed element enclosed in a container and firmly connected to the body of its wearer is released in an emergency, for example by means of a release cord, and unfolds (due to the dimensionally stable toughness of its material) automatically to a multiple of its original volume. The specific gravity of the accident victim is reduced and permits him/her to "swim on the avalanche". He/she is partially protected against mechanical effects and, in the case of being buried, against suffocation due to the absorbed ambient air, and in the latter case there is a hollow space available so that the accident victim can free himself/herself. The device can also be used for various leisure or other purposes. <IMAGE>

Patent DE-3308688-A1 (DE)
Title: Method for the rapid supercooling of organs and tissues
Inventor: MARTIN ERICH DIPL ING
IPC: A01N1/02
Filed: 1983-03-11
Abstract: The method for the rapid supercooling of organs and tissues permits uniform supercooling over the entire cross-section of bodies with hollow cavities allowing flow through them, this being not achievable with any of the conventional cooling methods. Suitable bodies of this type are, in particular, organs with their vascular network. These not only contain channels allowing flow through them but they are also of such a nature that every part of the organ is uniformly flushed. In biological tissue without vessels helium gas is capable, due to its small atomic dimensions, to flow through this tissue up to certain thicknesses. The better dissipation of heat as a result of compression of the helium gas can be implemented in a method in practice, because pressure acting upon all sides does not cause any irreversible damage to biological tissues.
