Title: Determination of correlation characteristics of binary series - uses sequential comparisons of pulse trains in two digital memories
Inventor: DAHM HANS-HENNING DIPL ING
IPC: G06F17/15
Filed: 1975-03-27
Abstract: A method for checking the complete correlation characteristics of digital pulse trains, in which n successive values of a first train fed into a digital memory (SR1) are compared with a value in a second memory (BS) to determine autocorrelation values and thence the parity with values from a second train. After each n operations of comparison in each memory a single successive pulse value is entered and a further n comparisons made. After N comparison series, where N determines the accuracy of the result, the results are used to step a binary counter forwards for parity and backwards for non-parity (Z1), with the numerical values fed after each step to a third memory (SR2, SR4) used to reset the first counter (Z1). The final result is extracted from the third memory (SR2, SR4) and related to the number of comparison series N.

Title: External control for cine camera drive motor - provides normal single-shot and accelerated photography
Inventor: AMPENBERGER WALTER ING GRAD
IPC: G03B19/18
Filed: 1975-04-22
Abstract: The device (2) connects to the remote-control terminals of a cine camera and provides a switch (relay 20, 21) through which the relay that starts the camera motor can be energised. It contains two monostable flip-flops (14) in tandem, the one (13) determining the time that will elapse before the next exposure, the other (14) the length of the shot. For a normal shot (a) (ganged switches (23, 22, 17) the time delay is fixed (time constant set by 25 and 26) and the length of shot variable (26' with 27). For a single-shot there is no delay and the length of shot is fixed. For speed-up photography (c) the delay is variable (29 with 26) and again the length of shot is fixed - but in this case the third of the ganged switches (17 at 19) couples the second flip-flop (14) back to the first (13), so that single exposures continue to be made with the set delay between until the device is switched off (main switch (16).

Title: Prolonged release amino cpds. prodn. - by reacting (meth)acrylic acid ester or amide reaction products with amino acids and copolymerizing
Inventor: DROBNIK JAROSLAV DR
IPC: C08F8/30
Filed: 1975-06-10
Abstract: New process converts active substance with an NH2 group into polymeric form, intended for prolonged release of the active substance by enzymatic cleavage. A substd. amide or ester of acrylic or methacrylic acid having a chain of is not 3 atoms in the side-chain terminating in the C-atom of the carboxyl group is condensed with the alpha-amino group of an L-amino acid. The active cpd. is then bound via its NH2 group to the carboxyl group of the amino acid. The resulting monomer is copolymerized with a hydrophilic monomer based on N-alkyl-(meth)acrylamide, or N, N-dialkylacrylamide ('alkyl' being 1-6C). The hydrophilic monomer may contain 1-3 OH groups or glycol (meth)acrylate ('glycol' being ethylene, propylene, butylene, diethylene or triethylene glycol, or homologous 2-6C polyglycols). The copolymerization can be carried out in the presence of smaller amts. of further monomers, which can act as crosslinking agents. The polymers permit regulation of the physical and biological behaviour of the active substance by variation of the character and molecular weight of the polymeric carrier. Rate of enzymatic cleavage can also be regulated by the length of the side-chain. The active substance is protected against premature excretion and against inactivation (e.g. histamine can be protected against the action of histaminase). Examples of L amino acids which can be used are phenylalanine, tyrosine, alanine, citrulline and ornithine. In an example, a copolymer contg. 97.6 mol. % N-(2-hydroxypropyl)-methacrylamide and 2.4 mol. % N-methacryloylglycylphenylalanyl nitroanilide is produced by direct copolymerization. The copolymer is used as a substrate for enzymatic cleavage by chymotrypsin.

Title: Contact-free tension measurement for steel strip cold rollers - features voltage converter in form of two separate coils set on same yoke
Inventor: WEBER ERNST ING GRAD
IPC: B21B37/48
Filed: 1975-07-24
Abstract: Contact-free tension measurement between the individual roller frames during cold rolling of strip steel is claimed. The strip tension measurement is taken to achieve a constant strip thickness at the output of the last roller frame of a tandem- or continuous strip roller line at constant roller speed or at constant rotary speed of the roller pairs of the individual frames. The resultant measurement series is a criterion for the roller gap regulation. The measurement is carried out by continuous measurement of the magnetic conductivity (permeability during tension oscillations in conjunction iwth a voltage converter. Specifically, the converter is in the form of the separate coils which are spaced widely apart and set on the same connecting yoke. This yoke comprises a material of good magnetic conductivity and connects two neighbouring frames of a line on the top side, simultaneously acting as support yoke.

Title: Flavonoids separation from impurities, e.g. tannins - by gel filtration in alcohol, ketone and/or ester solvents
Inventor: HIERMANN ALOIS DR PHIL
IPC: C07G3/00
Filed: 1975-11-05
Abstract: Sepn. of flavonoid aglycones and flavonoid glycosides, in drugs and plant extracts, is carried out in soln. in solvent, (I), selected from 1-4C alcohol, a lower aliphatic ketone and/or a lower alkyl ester of a lower aliphatic monocarboxylic acid. The soln. is separated into fractions by gel filtration and the flavonoid-contg. fraction is separated off. Eluant is solvent (mixt.) (I). The elution is carried out with a 1-4C alcohol, a lower aliphatic ketone or a lower alkyl ester of a lower aliphatic monocarboxylic acid, or with a mixture of such solvents. Gel filtration allows the major part of unwanted substances to be removed from the plant extract before the isolation and separation of the flavonoids contained in the extract. Method avoids interference withe adsorption chromatography procedures employed by contaminants such as tannins. In an example, a methanol extract of hawthorn fruit is subjected to gel filtration on a 'Sephadex LH 20' (RTM) column using methanol/ethyl acetate 1:2 as eluant.
