Title: Di:methyl-formamide prepn. from di:methylamine and formic acid - comprises bubbling di:methylamine through formic acid and DMF mixt.
Inventor: ZADORSKY VILIAM MIKHAILOVICH
IPC: C07C233/00
Filed: 1977-05-09
Abstract: Dimethyl formamide is pred. by reacting HNMe2 vapour with liq. HCOOH, heating the formate-dimethylamine-contg. liq. phase obtd. and recovering the end prod. Improvement comprises bubbling the HNMe2 vapours at 0.3-3 m/sec. through a mixt. contg. HCOOH and DMF. An upward-flowing vapour-liq. concurrent stream of reagents is formed. Formate-dimethylamine is produced in this stream. The steram is maintained for a time sufficient to convert 70-85% of formate-dimethylamine to DMF. The liq. and vapour phases are then sepd. The liq. phase is contacted, in countercurrent, with a new HNMe2 vapour stream at boiling temp. of reaction mixt. The prod. vapours formed contg. excess HNME2 vapour stream at boiling temp. of reaction mixt. The prod. vapours formed contg. excess HNMe2 combine with the previously recovered vapour phase and are discharged to separate the DMF by rectifying. DMF is used in refining ethylene and butadiene; in acetylene sepn. from olefins; H2S and S cpds. removal from C -contg. raw material and rubber; for aromatic hydrocarbon extn.; in working up synthetic resins, prodn. of lacquers, paints and pigments and in refining mineral oil.

Title: Precise angular tracking of radar target - utilises direction and bearing error signals to control aerial positioning servo-mechanisms
Inventor: BEGUIN DANIEL EDMOND
IPC: G01S13/68
Filed: 1977-06-03
Abstract: Precise angular tracking of an objective is obtained from a radar receiver which does not require very precise mechanisms in the aerial control system. A moving target is tracked using monopulse aerial producing bearing and direction signals and a sum signal. Signals are processed identically and passed to phase loop with phase discriminator to obtain differences in phase. These processed signals are converted to digital signals. Direction and bearing error signals are obtained and decoded to analogue signals to control antenna position servomechanisms.
