Title: Polyphenylene ethers
IPC: C08G65/44
Filed: 1976-11-09
Abstract: 1527669 Polyphenylene ethers GENERAL ELECTRIC CO 9 Nov 1976 [11 Nov 1975] 46674/76 Heading C3R In a process for the preparation of polyphenylene ethers which comprises passing elemental oxygen into a solution of a monovalent phenol in the presence of an aminemetal salt complex catalyst, there is added to the reaction mixture a compound of general formula wherein R<SP>1</SP> and R<SP>2</SP> may both be alkyl groups having 6-22 carbon atoms, alkenyl groups having 10-22 carbon atoms or one of R<SP>1</SP> and R<SP>2</SP> may be -(CH 2 CH 2 -O-) x H; x is an integer of from 1 to 40 and X- is an anion of a strong acid, e.g. Cl, Br, SO 4  and PO 4 . Depending upon when it is added the compound increases the reaction rate, aids catalyst removal and aids separation of the solvent from the non-solvent used to precipitate the polymer from the reaction mixture. Suitable compounds of Formula I are methylbis(2- hydroxyethyl)octadecyl and oleyl ammonium chlorides, methylbis(2 - hydroxyethyl)cocoammonium chloride, methyl polyoxyethylene dicocoammonium chloride containing 15 mols of ethylene oxide. These compounds may be used together with quaternary ammonium compounds having no hydroxyethyl groups. Compounds of Formula I may be used in amounts of from 0À01-0À2% by weight based on the monovalent phenol when added at the beginning of the reaction or from 10-200 p.p.m. of the solvent when added after the reaction. In a typical example oxygen is passed into a toluene solution containing 2,6- xylenol, a cupric chloride-di-n-butylamine complex catalyst and sodium bromide, at 30 C., for 75 mins.; 38% aqueous solution of the trisodium salt of ethylenediamine tetraacetic acid is then added; the mixture centrifuged; the upper layer decanted and methanol added to precipitate the polymer which had a copper content of <5 p.p.m.

Title: Process for producing salts of l-asorbic acid-2-sulphate
IPC: C07C303/06
Filed: 1974-10-29
Abstract: For the preparation of mono- or di-alkali metal salts or alkaline earth metal salts of L-ascorbic acid-2-sulphate, L-ascorbic acid is first protected with a ketone or an aldehyde in the 5- and 6-positions. The resulting product is then sulphated in dimethylformamide using a sulphating agent. The sulphating agent used is either sulphur trioxide, alkali metal chlorosulphonate or sulphuryl chloride, or chlorosulphonic acid in the presence of pyridine or urea. The reaction mixture is then neutralised with an alkali metal hydroxide or an alkaline earth metal hydroxide and the protective group is removed. High yields are achieved in this procedure. The mono- or di-alkali metal salts and alkaline earth metal salts of L-ascorbic acid-2-sulphate can be used as a poultry feed additive. They lead to an improvement in the strength and thickness of the eggshells.

Title: Agricultural haulm roller-type baling press
IPC: A01F15/07
Filed: 1977-11-11
Abstract: The roll-baling press is equipped with a pick-up device (4) and with an approximately cylindrical press space (1) following the latter. The cylindrical press space (1) is formed by a plurality of driven conveying rollers (2) which are arranged on its circumference and which are lined up next to one another. A drawing-in gap (3) is present between the conveying rollers (2) after the pick-up device (4). To increase the conveying effect in a circumferential direction, the conveying rollers (2) are designed in such a way that their surfaces have height differences in relation to their cylindrical enveloping circle. These height differences can be formed, for example, so that the conveying rollers are provided with a polygonal cross-sectional surface, for example a hexagon. However, the cross-sectional surface can, for example, also be elliptical. The cross-sectional surface can also be circular, in which case the axes of rotation of the conveying rollers are eccentric relative to their centre axes. <IMAGE>
