Patent DE-2342814-A1 (DE)
Title: Flue gas washer in horizontal duct - with liquid esp. calcium hydroxide sprayed transversely to gas flow
Inventor: JUN ALEXANDER WEIR
IPC: B01D53/50
Filed: 1973-08-24
Abstract: An apparatus for purifying chimney gases, comprises a long, horizontal chamber with gas inlet at one end and outlet at the other; the entire chamber is of uniform unobstructed cross-section throughout its length. A device for introducing a liquid reagent into the chamber, esp. a spray unit or several successive spray units, introduces the liquid reagent substantially perpendicularly to the flow of gas. The continuous unobstructed cross-section and the absence of contra-flow lead to reduced pressure drop. No materials which can become clogged occur in the gas path. A number of different reagents can be introduced in successive stages.

Title: Direction-finding system determining angle of incidence - involves phase comparison of low-frequency voltage with reference voltage
Inventor: EICHEL KLAUS DIPL ING
IPC: G01S3/14
Filed: 1974-06-05
Abstract: Between the direction-finding aerials (1, 2) and the heterodyne element (35) there are mixers (31, 32) in which the aerial signals are mixed with a low-frequency voltage of frequency f. This ensures that when all aerial signals are superimposed in the heterodyne element the voltage of one aerial is added to the voltage of the auxiliary aerial in the period corresponding to the first half period of the vibration of frequency f and it is subtracted from it during the following half period. A receiver in the component (36) is used to produce the low-frequency voltage whose phase relationship corresponds to the angle of incidence.

Abstract: In the homogeneous doping of a weakly n-conducting Si semiconductor with P, in which a Si semiconductor, which is undoped or doped only so slightly that any inhomogeneity in this doping is not noticeable after P-doping, is irradiated with thermal neutrons until sufficient 30Si is converted to P to give the required P concn., the radiation damage in the Si crystal lattice is healed, after decay of the radioactivity, by tempering briefly above 1000 degrees C. This treatment permits subsequent diffusion of a Gp. III element pref. Ga, to be carried out successfully.

Title: Cephalosporins from penicillin S-oxides - by treatment with ion-exchange resin in inert solvent
Inventor: CIESLAK JERZY PROF DR
IPC: C07D501/10
Filed: 1974-11-26
Abstract: Conversion of a penicillin sulphoxide (esp. of formula (I)) into a cephalosporin (esp. of formula (II)) comprises treatment with an ion-exchange resin in the presence of an inert solvent.

IPC: F16L27/12
Filed: 1975-06-11
Abstract: The two pipes for conveying away burnt gases are flexibly connected. The connection is temperature resistant and can be used in vehicle exhausts. One pipe (2) is of greater diameter than the other (1) and encloses its end. A cylindrical section (3) of greater diameter than the wider pipe (2), tapers down to the smaller pipe diameter, and is welded (5) to the smaller pipe (1) to sandwich the larger pipe end in between.
