Abstract: Prodn. of o-benzyltoluenes (I) of the formula A-B (in which A has the formula and B has the formula the R gps. are independently H or halogen and The R' gps. H, halogen or aliphatic or aromatic gps.) involves reacting o-xylyl halides (II) of the formula A-X (in which X is halogen) with benzenes (III) of the formula H-B in the presence of O-contg. cpds. (IV) of Al and Si. Reaction can be carried out (dis)continuously at 50-250 degrees C and press. up to 15 bar. It is pref. to operate without a solvent. (IV) pref. is an aluminosilicate with 1-95 mole Al2O3 per mole SiO2 and is used in amt. of 0.1-15 wt.% w.r.t. (II). (I) are valuable starting materials for the prodn. of anthracene, anthraquinone and their derivs. The process is simple and cheap, free from trouble and corrosion problems and gives (I) in good yields and purity, even at low reaction temps. Readily available starting materials are employed and no multistage syntheses are need for their prodn. The formation of sulphonation prods. is avoided and the protection of the environment is improved. In an example an o-benzylchlorotoluene isomer mixt. was obtd. in 87% yield from chloro-o-xylyl chlorides and benzene by heating 4 hrs. at 145 degrees C and 11 bar in the presence of Al silicate (10 wt.% Al2O3).
Patent DE-2549093-A1 (DE)
IPC: G07D5/08
Filed: 1975-11-03
Abstract: The method and the device are used to monitor sound-conducting media. Sound vibrations are transmitted to the medium (1) by a sound generator (31). At the same location, sound vibrations are retransmitted by the medium. The transmission of the sound vibrations to the medium is performed periodically during specific frequency sweep periods (S), and the reception of the sound vibrations by the medium is performed during the successive intermediate times (R) between the periodic frequency sweeps (S). The amplitude or phase variation in the recorded sound vibrations during a total period (S+R) is compared with the variation in one of the preceding periods. If specific deviations occur in the two periods, an alarm signal is triggered. The method and device are particularly suitable for protection against burglary, i.e. for example for monitoring glass panes for damage. <IMAGE>

Title: Multilayer optical waveguide - produced by flame hydrolysis of doped silicon compound on half substrate rod periphery and wire drawing
Inventor: LANGHEINRICH WERNER DR RER NAT
IPC: B23K26/12
Filed: 1976-04-17
Abstract: A multi-layer optical waveguide for use in broadband in formation transmission systems for light signals is produced by depositing the optically active layers on the surface of an optically inactive substrate such as a cylindrical rod. The optically active layers cover half of the rod periphery. In a final drawing operation, the cross-section is reduced and an optical light guide fibre is produced. This is a simple and inexpensive process for the mfr. of optical light guides with a very low attenuation. The plateau in the refractive index curve in the centre in the case of concentrically coated rods and the occurrence of a minimum in the case of internally coated tubes have been eliminated.
