Title: Bis-anhydrides and realted compounds
IPC: C07D307/91
Filed: 1972-03-08
Abstract: 1388712 Bis-anhydrides; derivatives thereof RAYCHEM CORP 8 March 1972 [10 March 1971] 10735/72 Heading C2C [Also in Division C3] Novel compounds have the Formula Ia wherein each of the identical radicals Z is -O-, -S- or >N-Y, Y is an alkyl radical, A is a divalent polynuclear aromatic radical, other than a linear polyarylsulphone radical, whose valence bonds stem from nuclear carbon atoms and R 1  and R 2 , which may be the same or different, are trivalent aromatic radicals. The invention also comprises the tetraacids and diacid-anhydrides corresponding to the bis-anhydrides of Formula Ia. The compounds of Formula Ia are prepared by reacting at least two molar equivalents (e.g. 2 to 4) of at least one compound of Formula II  wherein X represents halogen, or of the corresponding acid halides where the -O- radical is replaced by -S- or >N-Y, with one molar equivalent of a compound of formula by a Friedel-Crafts reaction under conditions disfavouring the acylation of the anhydride, &c. moieties. The reaction is preferably effected using FeCl 3  as catalyst and in the molten state. In a modification of the process, the free monocarboxylic acid acid anhydride is used as starting material in place of compound II and the catalyst is a polyphosphoric acid or trifluoromethane sulphonic acid. Polyimides, polyamic acids and polymidazopyrrolones are prepared from the bis-anhydrides of Formula Ia. The examples describe the preparation of (1) 4,4<SP>11</SP>-bis-(benzophenone-3<SP>1</SP>,4<SP>1</SP>-dicarboxylic acid) dianhydride, (2) 4,4<SP>11</SP>- oxybis - (benzophenone - 3<SP>1</SP>,4<SP>1</SP> - dicarboxylic acid) dianhydride, (3) 4,4<SP>11</SP>-isopropylidenebis(benzophenone - 3<SP>1</SP>,4<SP>1</SP> - dicarboxylic acid) dianhydride, (4) 4,4<SP>11</SP> - ethylenebis - (benzophenone - 3<SP>1</SP>,4<SP>1</SP>- dicarboxylic acid) dianhydride, (5) 4,4<SP>11</SP>-(fluorene - 2<SP>1</SP>,7<SP>1</SP> - dioyl)diphthalic acid dianhydride, (6) 4,4<SP>11</SP> - (dibenzofuran - 3<SP>1</SP>,6<SP>1</SP> - dioyl)diphthalic acid dianhydride and (7) 4,4<SP>11</SP>-(anthracene- 9<SP>1</SP>,10<SP>1</SP> - dioyl) - diphthalic acid dianhydride via the corresponding tetra-acids.

Title: Animal handling apparatus
IPC: A01K15/00
Filed: 1963-03-19
Abstract: 960,804. Animal handling devices. W. R. C. GEARY. March 19, 1963 [March 19, 1962], No. 10747/63. Heading A5R. Apparatus for the handling and treatment of animals, such as sheep, comprises a plurality of carriers 50, having means 56 for suspending an animal by its legs, the carriers being mounted for intermittent rotation around a central support 10. The carriers 50 comprise four pneumatically actuated leg clamps 56, two of which are mounted on curved arms 54 secured to one end of a box section girder 51 while the other two are on arms 58 mounted on a carriage which is adjustable along the length of the bar 51. The hub assembly 24 is supported on the column 10 by means of ball bearings and is rotated intermittently by a pawl arrangement actuated by a pneumatic piston and cylinder 33. Operation of this mechanism auto. matically couples the hub assembly to a pneumatic dashpot 43 which retards forward motion of the carriers and ensures that they stop promptly at each station. A loading unit 70 is located at the loading station and comprises a trough shaped holder 71 in which the animal is placed with its feet uppermost. This mounted on pivoted, parallel links 72 (see also Fig. 11 (not shown), so that it can be raised, by a pneumatic jack 77, to the position shown dotted where the animal is in the position for having its feet placed in the clamps 56. At the unloading point the animal is released and drops into a similar trough 80. In this case, however, the rear wall 85 and bottom are pivoted to a supporting frame 83 and the front wall 86 is pivoted to the bottom so that, as a pneumatic jack 90 is lowered, the whole assembly is first tilted outwards and then the front wall 86 is lowered on to a guide plate 84 so that the animal rolls over and slides to the ground, feet first. If it is desired to support an animal's back, at an intermediate treating station, so that it is held straight, a channelshaped member 101 on a pneumatic jack 103 may be used.

Title: Improvements in the saponification of filaments, fabrics, films and the like of organic esters of cellulose
IPC: D01F2/28
Filed: 1937-04-15
Abstract: Filaments, ribbons, &c. having a basis of organic esters of cellulose are saponified by N-alkyl or N-aralkyl derivatives of cyclohexylamine.  The cellulose esters may be simple esters such as cellulose acetate or ether-esters such as ethyl cellulose acetate and oxyethyl cellulose acetate, or mixed esters such as cellulose acetate propionate and nitro-cellulose acetate.  The cyclo-hexylamine derivative may be a mono- or di-alkyl or aralkyl cyclohexylamine and is preferably applied to the cellulose ester materials in an aqueous bath, but non-aqueous baths may be used. A swelling repressing agent of the type mentioned in Specification 453,302 may be used or it may be a salt formed during the saponification such as methyl cyclohexylamine acetate.  The cellulose ester materials, which may have previously been stretched and optionally afterwards shrunk, may be treated by drawing them continuously through the saponifying bath or they may be treated in fabric, hank or package form.  The saponification may be carried out at high temperatures or at super-atmospheric pressures and it may be allowed to proceed to any desired stage.

Abstract: 527,328. Saponifying cellulose ester materials. BRITISH CELANESE, Ltd. April 6, 1939, No. 10764. Convention date, April 6, 1938. [Class 2 (ii)] Textile materials such as filaments, yarns, fabrics and the like containing an organic ester of cellulose are saponified in the presence of pine oil defined as an oil obtainable from pine trees which oil comprises as essential constituents terpene alcohols, mainly α- and #- terpineols. The saponifying agent employed may be an alkali metal hydroxide or carbonate, ammonium hydroxide or an aliphatic amine such as diethanolamine or triethanolamine. The saponification may be effected by the winch method even when the materials treated, for example, crepe fabrics, contain high twist cellulose ester yarn. The saponification may be incomplete but sufficient to impart an affinity for cotton dyes to the cellulose ester materials. Cellulose esters mentioned are cellulose acetate, cellulose propionate and cellulose butyrate and these may be present in admixture with other textile materials, for example, regenerated cellulose, cotton, wool and silk.
