Patent WO-0224484-A1 (WO)
Inventor: KAZMIERCZAK HARALD
IPC: B60R16/02
Filed: 2001-08-28
Abstract: The invention relates to an inductive transformer for transmitting measuring data and/or electrical energy between two components (1, 2) which can move in relation to each other, comprising a primary and a secondary transformer part (4, 5), a gap being formed between the movable components (1, 2) . A sliding ring (6; 7) consisting of a plastic with imbedded ferromagnetic metallic parts is located in said gap. The metallic parts are so inhomogenously distributed in the plastic that their proportion is high at the end with which the ring is fixed on one of the components (1, 2) and becomes relatively low towards the end with which it rubs on the other component (1, 2), respectively.

Title: Continuous preparation of sorbic acid
Inventor: GERHARD KUENSTLE DIPL-CHEM DR
IPC: G09F15/00
Filed: 1969-03-14
Abstract: Continuous preparation of sorbic acid Ketene is reacted at 60-102 degrees with an excess of crotonaldehyde, containing as stabilising agent 0.01-1% sterically hindered phenol, in the presence of a catalyst. The catalyst consists of tetra-alkyl titanates and a co-catalyst comprised of one or several acid compounds. The polyester formed is hydrolysed with mineral acid, after removal of excess aldehyde, to form sorbic acid. The crude acid undergoes a complementary heating for 1-5 hours at 70-90 degrees followed by washing out of the mineral acid and neutralising of the last traces of the acid.

Title: Control of density of syrups
Inventor: VALENTIN PETER
IPC: C13B25/00
Filed: 1969-05-13
Abstract: Control of density of syrups (syrup solutions obtained by multistage evaporation of water from thin syrups, particularly of sugar) comprises measuring the density of the thin syrup, and from this calculating a first value for water evaporation, and assuming a definite value for the density of the thick syrup. The syrup passes through a series of evaporators, and if there are deviations between the calculated (first) value of water evaporation and the value found, this is adjusted by means of a valve in an overflow stream for evaporating liquid, placed between two of the evaporation stages.
Patent DE-1924710-A1 (DE)
Title: Cryptoaescin prodn
Inventor: JOSEF WAGNER DR RER NAT
IPC: C07H15/256
Filed: 1969-05-14
Abstract: An alpha-aescin-contg. aqs. soln. of pH 4.8-6.0 is treated with finely powdered cholesterol in suspension at 90-100 degrees C until the haemolytic aescin isomers are bound to the cholesterol and cryptoaescin is recovered from the filtrate either in non-haemolytic solid form or, after partial re-isomerization to alpha-aescin, as an isomer mixture of constant haemolytic activity. The starting alpha-aescin-contng. soln. may, instead of a pure saponin soln., be a horse chestnut extract. The process represents a method of simultaneously removing beta-aescin and converting alpha-aescin into cryptoaescin or into a mixture of crypto- and alpha-aescin.
