Inventor: METZGER CARL DR
IPC: C07C307/02
Filed: 1976-10-16
Abstract: Sulphuric acid diamides of formula R-C6H4-NH-SO2-NME (I) (where R is H, Me, F or Cl) are prepd. by reacting dimethylamino-sulphochloride having formula Cl-SO2-NMe2 (II) with an aniline having formula R-C6H4-NH2 (III), in the presence of inorganic reducing agents, (IV), and of acid binders, at pH 3-5, 40-80 (45-70) degrees C, in water as diluent. (I) are intermediates in synthesis of pesticides, plant-protective fungicides and dyes. (i) Addn. of (IV) gives a smooth, quicker reaction. (ii) Highly pure (I) is obtd., requiring no further purificn., the moisture content being low. (ii) Cooling may take place by using warm industrial recycle water. In an example, use of NaHSO3 as (IV), in prepn. of PhNH-SO2-NME2 from (II) and aniline, increases yield from 82- to 92%; reduces reaction time from 30- to 20 hrs., increases purity to 99% and reduces moisture content from 25- to 8%.

Title: Plastics foil sheeting frame tent or green house - has one-piece foil section with arcuate cuts for snug fit round gables without excessive gathering
Inventor: BECKMANN GERHARD
IPC: A01G9/14
Filed: 1977-07-29
Abstract: The support frame is covered by a one-piece sheet of foil (9) which fits over the sides of the gable where on the side remote from the access door it is cut straight where the side edges of the gable are straight and curved where the side edges are curved so that the cut edges can be attached to a ridge (4, 16) fitted in the vertical or if required inclined centre axis of the gable side. The curved cut edges which are associated with the curved edges of the gable side can then be placed in folds which provide a neater appearance and requires less foil material than in those constructions where the foil is gathered up. The gable side remote from the access door is thus designed as a gable wall with a central ridge assembly which takes up both cut edges of the foil whilst the folds only occur where the side edges curve.
