Title: Railway system for combined road - rail traffic - uses double car transporter, which has double wheel sets, to move on two adjacent railway tracks
Inventor: PERDOLT GOTTFRIED
IPC: B61B13/00
Filed: 1992-12-04
Abstract: The system uses a route, which may have at least two parallel standard gauge tracks. Each track may have two or more rails. It has a road vehicle transporter (2), with at least two neighbouring wheel sets (12,13) on both sides. The wheel sets are located on bogies (9,11), and move on the rails. The transporter has at least one level, on which road vehicles (46) are parked at an angle to the direction of travel. Both side walls of the transporter are shaped to permit vehicles to move on and off. The end walls are angled from the centre towards the side walls. The transporter is a double-decker, and the top storey is for transportation of cars or passengers. USE/ADVANTAGE - Giant rail transporter wagon for road vehicles increases use of railway lines, eases loading and unloading of road vehicles, removes traffic from roads and may use existing double track or four-track railway line with little modification.

Title: Mitred corner connection
Inventor: HUSTADT ACHIM
IPC: E06B3/976
Filed: 1993-02-22
Abstract: The invention relates to a mitred corner connection for frame parts made up of hollow profile bars, in particular for windows, doors and the like with corner angles inserted in the mitred corner regions. The aim of the invention is to design a mitred corner connection such that it can be produced cost-effectively and joining of the frame parts to be connected is simplified. In addition, the intention is to achieve, over the greatest possible leg length, a sufficiently uniform abutment of the corner-angle part-legs against the inner walls of the frame parts. This object is essentially achieved in that each corner angle is designed as a single-piece, extruded hollow-chamber profile angle which exhibits a longitudinal slot which runs parallel to its leg abutment surfaces and terminates in front of the free leg ends, in doing so forming bridge webs. In addition, by mechanical deformation, clearances, which each also contain a sub-region of the longitudinal slot, are pressed directly into the corner angles. Consequently, the advantages of a multi-part mitred corner connection are combined with the advantages of a single-piece extruded corner angle, but, at the same time, disadvantages thereof are avoided. <IMAGE>

Title: Device on the lock of the belt of a motor vehicle seatbelt for detecting whether the seatbelt has been put on
Inventor: NITSCH ERIK DIPL ING
IPC: B60R21/01
Filed: 1993-08-20
Abstract: The invention relates to a device on the lock (8) of a motor vehicle seatbelt for detecting whether the seatbelt has been put on, which device comprises according to the invention a circuit (2) with two parallel line branches (3, 4) with in each case resistors (R1, R2) which are of different sizes and are arranged therein. On both sides of the line branches (3, 4) change-over switches (5, 6) are arranged which are actuated mechanically in such a way that depending on whether the belts have been put on either the one line branch (3) or the other line branch (4) is connected into the circuit (2). The respective resistance value, and thus whether or not the belts have been put on, is determined in an evaluation unit (7). When a change-over switch (5, 6) fails, this corresponds to a break in the line which is detected by the evaluation unit (7) so that simple functional monitoring of the change-over switches (5, 6) is possible with the arrangement. <IMAGE>

Title: Decarburising and degassing of steel melts in converter
Inventor: CHOUDHURY ALOK DR
IPC: C21C5/28
Filed: 1994-02-18
Abstract: A method for decarburising of steel melts is novel in that a melt to be treated is treated in a first step by adding oxygen at atmospheric pressure and in a second step by adding oxygen under vacuum. Both steps are carried out one after the other in the same treatment vessel.  Also claimed is a similar method to the above, but where the second process is carried out solely under vacuum with no oxygen addition.  The treatment is a decarburising and/or degassing process to set the C, S and H2 values of the melt.  A converter is used as the treatment vessel, the converter having a dust protection lid and a vacuum lid and being fitted with nozzles within the melt.  Through the nozzles, oxygen, a mixt. of oxygen and inert gas or inert gas can be introduced into the melt.  Pref. the converter has an oxygen blowing lance.  At the end of the first process step at atmospheric pressure, the carbon content in the melt is greater than 0.2%.  The carbon content after the end of the second process step under reduced pressure is less than 0.08%.  The melt comprises structural, high grade or special steel.  The pressure in the treatment vessel during the decarburising in the vacuum process step is 20-200 hPa.  The pressure in the treatment vessel during the degassing in the second process step is less than 2 hPa.

Title: Separating returning radio signal sections from composite sum signal, for use in e.g. mobile radio network
Inventor: WANIERKE OTMAR DIPL PHYS
IPC: G01R23/167
Filed: 1994-09-01
Abstract: A process for separating high-frequency radio signals from multi-layered composite signals operates on the principle of Fourier transformation. E.g. two signals (1,2) operating within the same predetermined frequency band and sent from two different transmitters (4,5), and are received as a composite signal (3) at a receiver (6). The received signal passes through an analogue/digital converter (7) and I-Q demodulator (8) to digital filters (9). The digital values are then converted with reference to their respective time zones, where the distance (T) between neighbouring time values is used in a Fourier transformation processor, where (T) is greater than the sampling interval. The DFT processor, preferably a special high-speed Fourier transformer based on the Cooley-Tukey-Radix or a Prime-Factor-FFT, changes the digital time zone reading into a spectrum, which is input direct into a data memory, before further processing. The signal sections are accumulated at difference frequency portions in the spectrum, enabling separation of the sections.
