Title: System for transmission of a report from mobile system users to a central station with little delay, particularly for traffic emergencies
Inventor: NUESSGEN MANFRED DIPL ING
IPC: G01S5/04
Filed: 1977-09-13
Abstract: Particularly in emergencies involving motor vehicles (1), there is the problem of locating such an emergency quickly and reliably, and initiating rescue procedures. This system includes a reporting system, which can monitor a whole urban area, for example, at acceptable cost. The given area is covered by a network of relay stations (2 - 5), which are connected to a central station (6) via the public telephone network. Mobile system users (1) have a radio transmission device. The density of the relay stations (2 - 5) is chosen so that in normal reception conditions at least two of the relay stations receive a report. Reports are stored in the relay stations until they can be securely transmitted to the central station (6). The relay stations have an identification generator, and a system for finding the direction of the system user who is sending the report. Using this and the transmission of the relay station identification, the location of the reporting system user can be quickly and exactly determined in the central station. The number of relay stations can also be kept low in this way. As a useful extension of the system, a speech connection between the central station (6) and the mobile system user (1) can be made. <IMAGE>

Granted: 1971-11-12
Abstract: The mfr. of sausages, as well as rolled joints of meat and bacon, involves the tight tying of the products by means of string, this has hitherto been done by hand. The new machine gives the same results but is entirely automatic. The machine comprises means for clamping the pieces of meat which are rotated at a constant speed and means for pushing the meat to allow a piece of string, attached to the meat, to be wound around the latter in a spiral path along the length of the meat, to be wound around the latter in a spiral path along the length of the meat. The pusher is driven along guides and is connected to an endless screw with right and left-hand threads, so the pusher can be moved backwards and forwards while the screw continues to turn in the same direction. While the string is being-wound around the rotating piece of meat, the latter advances under the action of the pusher so that the string follows a spiral path in the traditional manner. Operation is extremely simple and automatic.
