Title: Rescue tools of all types for people who are trapped or locked in
Inventor: ZURELL ARNOLD
IPC: A62B3/00
Filed: 1992-12-15
Abstract: Unfortunately, the fire service only has costly special rescue tools for people who are trapped or locked in. The rescue tools, shears and spreaders may only be used by trained firemen. When there is a risk of fire or explosion, every vehicle road user has to be able immediately to intervene and perform a rescue using the legally prescribed rescue tools of all types. Solution: using a sledge hammer or mallet covered with rubber or plastic, screw-shaped rescue tools of all types are knocked into the crushed body panel or door panel tip first, up to the beginning of the thread. The hammer handle, mallet handle, a tube, spanner or metal rod are used to grasp the eye, hooks, toggle-shaped or cross-toggle-shaped rescue screws and are simply turned until said screws fit absolutely tightly. The tow-cable is fastened in the eye, hooks, toggle or cross-toggle and then the locked-in or trapped people are very rapidly freed by pulling by hand or using a vehicle. Special training is, of course, not required. The rescue tool is very inexpensive and can be used or put away very rapidly in all locations. Rescue tools of all types, like the first aid box, have to be present in every vehicle by law.

Patent DE-4316098-A1 (DE)
Title: Interference microphone
Inventor: KUEPER MARTIN DIPL ING
IPC: H04R3/02
Filed: 1993-05-13
Abstract: A microphone arrangement is provided which is called an interference microphone and by means of which it is possible to reduce the feedback hazard in sound systems in large rooms beyond a measure which is otherwise not possible using known electronic means together with the directional microphones usually used. Due to its design, the microphone arrangement additionally utilises the curvature of wave fronts for suppressing feedback. In rooms with highly reflective boundary surfaces such as are frequently used for large auditoria, long reverberation times and little capability of modulating the sound system because of the feedback hazard normally lead to poor intelligibility. Since, as a rule, it is not easily possible to change the acoustic properties of the room in such a manner that existing sound systems can be modulated more without problems, it is attempted to improve the sound system with respect to feedback attenuation. The basic principle is that the useful sound to be transmitted, which is generated in the immediate vicinity of the microphone, exhibits greatly curved wave fronts. In contrast, sound waves, the origins of which are far distant from the microphone, have virtually plane wave fronts.

Title: Method for digital signal transmission
Inventor: LUDSZUWEIT AXEL DIPL ING
IPC: H04L25/49
Filed: 1993-06-24
Abstract: A method is indicated for digital signal transmission, with which bits of a binary data stream are transmitted using a converter as a pulse amplitude-modulated transmission signal with at least four amplitude stages via a line with metal conductors. To convert the binary data, bit combinations in each case of n >/= 2 temporally consecutive bits of the binary data stream are initially converted by a coder into one of 2<n> addresses corresponding to 2<n> amplitude stages of the transmission signal. Depending on the respective current bit combination, an address is then transmitted from the coder to a memory in which a number of pulse strings with different keying ratios corresponding to the number of amplitude stages of the transmission signal are stored. One of the pulse strings is assigned in each case to one of the amplitude stages. According to the respective address of the coder, one of the pulse strings is then loaded in each case into a parallel/serial converter. The contents of the converter are continuously read out and fed to a forming unit whose output signal is forwarded to the line as a transmission signal.

Patent DE-4325842-A1 (DE)
Title: Fuel injection valve
Inventor: STROHSCHEIN HEINRICH
IPC: B01D35/02
Filed: 1993-07-31
Abstract: In fuel injection valves which are already known, fuel filters are press-fitted into a fuel inlet stub and thereby fixed therein. This method of fixing gives rise to the risk of abraded particles and shavings, which can lead to malfunctioning of the fuel injection valve. In addition, holding collars for upper sealing rings are designed as separate components. The new fuel injection valve has a fuel filter (61) which is of one-piece configuration with a holding collar (60). The holding collar (60) extends radially beyond the fuel inlet stub (2) and has a protruberance (65) outside the fuel inlet stub (2). Together with the groove (66) on the outer circumference of the fuel inlet stub (2), the encircling protuberance (65) on the holding collar (60) forms a snap-in connection by means of which the fuel filter (61) is fixed in a defined manner. Between the main body (67) of the fuel filter (61) and the inner wall of the fuel inlet stub (2) there is only a clearance fit and any formation of shavings in the interior of the fuel injection valve is thus avoided. The fuel injection valve is suitable, in particular, for use in fuel injection systems of spark-ignition engines. <IMAGE>
