  • Publication number: 20250092474
    Abstract: The application relates to compositions based on maple sap, fruit juice and/or vegetable juice having a high added value. In particular, said compositions have high concentrations in polyphenols, phosphorus, magnesium, calcium and potassium, for example. These concentrations are higher than those in maple sap made by previous traditional or commercial processes and higher than those in fruit or vegetable juices or syrups. Furthermore, said compositions have an antioxidant effect that is also higher than that in commercial maple sap made on an industrial or small scale and higher than that in commercial fruit or vegetable juices or syrups. The application also relates to processes for making such compositions.

  • Patent number: 5174479
    Abstract: A shirt having a longitudinally extending body with a front and a back, a collar at a top end of the body, sleeves projecting from sides of the body, and buttons on the front of the body, is folded by first orienting the shirt flat with the body and arms generally coplanar and then folding side parts of the body inward along longitudinal fold lines and folding the sleeves down to lie on the folded-in side parts. Then a bottom part of the body is folded up against the back of the body along a transverse fold line such that a portion of the bottom part projects upward past the collar and some of the front buttons are positioned on the back of the folded-up bottom part. The projecting portion of the bottom part is then tucked between the folded-in side parts and the back of the body to impart to the shirt a generally rectangular shape.

  • Patent number: 4071517
    Abstract: A double salt comprising a material obtained by heating a mixture of equi-molar proportions of a theophylline alkanoic acid having the formula:R.sub.1 -- (CH.sub.2).sub.n -- COOHwherein R.sub.1 is a theophyllyl group which may be substituted by a halogen atom and n is an integer from 1--4; an aminocarboxylic acid containing sulphur having the formula: ##STR1## wherein R.sub.2 represents a hydrogen atom, a methyl group, or a --CH.sub.2 COOH group; n' is an integer equal to 1 or 2; R.sub.3 represents a hydrogen atom or a --COCH.sub.3 group; R.sub.4 represents a hydrogen atom and when sulphur and nitrogen are in a heteromonocyclic ring, n' is 1, and R.sub.2 and R.sub.4 represent a methylene group and ethylene-diamine. The compounds have remarkable effects in the treatment of respiratory complaints.
