Title: Magnetic recording tape - using binder comprising polyester with sodium sulphonate gps. and polyurethane prepolymer
IPC: G11B5/702
Filed: 1980-07-03
Abstract: Magnetic recording material comprises a substrate coated with a magnetic layer consisting of (a) a magnetic powder and (b) a binder comprising a polymer (I) with -SO3Na gps. and a polyurethane prepolymer (II). The (I) is pref. a polyester contg. -SO3Na gps. The binder may also contain other polymers such as thermoplastic polyurethanes, nitrocellulose, vinyl chloride-vinyl acetate copolymers, polyesters contg. no -SO3Na gps., etc. The magnetic layers can be cured e.g. with a polyisocyanate crosslinking agent. Use of polyesters contg. -SO3Na gps. in the binder compsn. promotes good dispersion of the magnetic component without the necessity for incorporating additional surface active agents, as in prior art materials. The prods. are esp. useful as video recording tapes with excellent physical and electromagnetic characteristics, including good wear and durability, good frequency response and high signal/noise ratio.

Title: An oxidative biological purification process for waste water
IPC: C02F3/12
Filed: 1980-08-05
Abstract: An oxydative biological purification process for waste water, comprising passing the waste water through an oxidation space containing aerobic activated sludge at such a rate, that the residence time in the oxidation space is between 0.3 and 20 h and a space load of COD of 4-50 kg/m<3> day and of nitrogen of at most 2.5 kg/m<3> is achieved, maintaining in the oxidation space a pH between 5 and 9 and substantially completely separating the purified waste water flowing out of the oxidation space from aerobic activated sludge and recycling the separated sludge into the oxidation space, the aerobic activated sludge being attached to a carrier and being separated from the waste water leaving the oxidation space by settling. 
<??>According to a preferred embodiment the settling tank is placed at a higher level than the oxidation space in order to avoid special provisions (e.g. recycle lines with pumps) and to save the floor space. 
<??>Preferably the aerobic activated sludge is attached to sand having an average granular size between 0.1 and 2 mm. 
<??>The purification is preferably carried out at a temperature of 10-60 DEG C. 
<??>The process enables a reliable waste water purification, even when the COD of the waste water is strongly varying and even when varying amounts of waste water are available, and supervision by skilled persons is practically not necessary.

Title: Process for preparing asymmetric hydantoins
Inventor: URBAN FRANK JOHN
IPC: C07D491/107
Filed: 1985-08-19
Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.
