Title: Ester resins
IPC: C08G63/46
Filed: 1947-04-28
Abstract: Resinous esters are produced by heating to a reacting temperature a polyhydric alcohol, an aliphatic dibasic acid or anhydride and a fatty monobasic acid containing from 12 to 22 carbon atoms or oil thereof in the presence of a common solvent, the process being characterised in that the aliphatic dibasic acid contains not more than 5 carbon atoms and that the solvent is a diether of a mono- or poly-ethylene glycol having the formula R1-O(CH2.CH2O)n-R2, where n is an anteger from 1 to 4 and R1 and R2 are alkyl groups containing from 1 to 4 carbon atoms, the diether being present in an amount to secure a homogeneous mixture at said reacting temperature.  Specified are, solvents: lower alkyl diethers (methyl, ethyl, propyl, or butyl) of mono-, di-, tri-, and tetra-, ethylene glycols or the cyclic diethers, e.g. dioxane; polyhydric alcohols-glycol, glycerol, pentaerythritol, sorbitol; dibasic acids-maleic, succinic, malic, tartaric, citraconic, or itaconic acids; fatty acids-lauric, myristic, palmitic, stearic, linoleic, linolenic, oleic, ricinoleic, or clupadonic acids, obtainable by hydrolysis from oils, e.g. linseed, castor and dehydrated castor, soya, perilla, other vegetable and fish oils, or the oils themselves or the mono-and diglycerides of the acid may be used. Rosin may be added to the reaction mixture. Part of the aliphatic dibasic acid may be replaced by phthalic acid. The polyhydric alcohol and fatty acid may be reacted in the solvent before the dibasic acid is added.  The solvent may be miscible with the polyhydric alcohol only on heating, and even then not necessarily in all proportions.  In examples the following mixtures are heated: (1) succinic anhydride, glycerol, linseed oil fatty acids and tetramethylene glycol dimethyl ether; (2) maleic anhydride, glycerol, soy bean fatty acid, diethylene glycol di-ethyl ether; (3) as in (2) but the maleic anhydride is added to the previously reacted glycerol, soy bean fatty acid and solvent.  Succinic anhydride may be substituted for the maleic anhydride; (4) dioxane is substituted for the solvent of (2) and the reaction is performed at 300 lbs. pressure and 220 DEG  C.  In each case some solvent is left in the resin to act as plasticiser.

Multiple machines; raising, lowering, and positioning sound-boxes; tool arms and mountings; tone-arm joints. -The sound-box of a disk talking- machine is automatically lifted at the completion of one record and is carried to the starting position of a record on another turntable, thus enabling a continuous reproduction to be given. As shown in Fig. 1, two record tables are provided mounted on spindles 9, 11 and geared together by a belt 14 or by other mechanism. Preferably one of the turntables overhangs the other. The tone-arm 4 carries a clamp 16 to which is pivoted a bracket 18 pressed down by a spring 19 on the pivot 17. The end of the bracket towards the spindle 11 of the second turntable carries an arm 20 pivoted on a pin 22 which may be adjusted along a slot 23. One end of this arm 20 has a flexible connexion 27 to an upstandmg arm 32 on the gooseneck 7 carrying the soundbox 6. One face of the arm 20 is covered with a strip 34 of rubber or like frictional material, and the upper end of the spindle 11 is provided with a rubber sleeve 35. Upon the completion of the first record, the arm 20 engages the spindle 11 and turns on its pivot 22, causing the sound-box 7 to be raised. The rotating spindle 11 then drags forward the arm 20 and places the sound-box over the rim of the second record, upon which it is gradually lowered as the bevelled end of the arm 20 moves over the spindle 11. The initial adjustment of the arm 20 is obtained by placing the needle in the final groove of the first record. The bracket 18 and arm 20 may be arranged below the turntables, and by providing a second bracket and arm, a third record may be reproduced. The frictional engagement of the arm 20 and the spindle 11 may be maintained magnetically, and both may be provided with teeth to give a rack and pinion action. In order to permit of the use of larger record disks, a short tube with bayonet connexions may be interposed between the sound-box 6 and the gooseneck 7. The sound-box may have two stylus arms, spaced apart circumferentially, and one shorter than the other, the shorter stylus coming into action on the higher turntable owing to the tilt of the gooseneck.
