Patent GB-455922-A (GB)
Title: Mixed ester derivatives of glycol and compositions containing the same
Filed: 1935-04-27
Abstract: Waxy or viscous esters which are not thermohardening are obtained by reacting an aliphatic dicarboxylic acid with a slight excess of a glycol while moderately heating to produce esters of the formula HO--R2--O--(--CO--R1CO--O--R2--O--)nH, where R1 is an alkylene group or a simple bond and R2 the radical of an alkylene or polyalkylene glycol, and arresting the reaction when the value of n is between 2 and 10 by esterifying the terminal OH groups with a saturated aliphatic monocarboxylic acid containing not more than 6 carbon atoms or its anhydride. The fact that n has reached the desired value is determined by the amount of water liberated.  The dicarboxylic acid may be succinic, oxalic, or adipic and the monocarboxylic acid acetic, propionic or butyric.  Ethylene glycol succinate acetate has been prepared in which n has a value of 8, 5 or 3.  The esters are plasticizers and solvents for cellulose derivatives and synthetic and natural resins and gums used in coating and impregnating compositions, films and moulded articles.  Thus films may be obtained by dissolving equal parts of diethylene glycol succinate acetate (M.W. 1950) and nitrocellulose in the usual lacquer solvents.  80 parts of acetone soluble cellulose acetate and 20 parts of the same plasticizer may similarly be used.  In an example, ethylene glycol and succinic acid are reacted in the presence of sulphuric acid at 140 DEG  C. and 350 mm.  Acetic anhydride is added and heating continued at 100--110 DEG  C.  The purified product has a molecular weight of 1340.  Triethylene and diethylene glycol succinate acetate are made in somewhat similar manner, the molecular weight varying between 1000 and 2000 according to temperature and time of reaction. British Specifications 24254/12, 22544/13, [both in Class 2 (iii)], and 388,367, and U.S.A.  Specification 1,922,646 are referred to.ALSO:Esters obtained by reacting an aliphatic dicarboxylic acid with a glycol to form an ester of the formula HO--R2--O--(--CO--R1--CO--O--R2--O--)nH, where R1 is an alkylene group or a simple bond and R2 the radical of an alkylene or polyalkylene glycol, and arresting the reaction when the valve of n is between 2 and 10 by esterifying the terminal OH groups with a saturated aliphatic monocarboxylic acid containing not more than 6 carbon atoms or its anhydride, are plasticizers and solvents for resins and gums used in coating and like compositions.

Title: Improvements in and relating to Adding Machines.
Inventor: WHITE ALFRED ERNEST
IPC: G06C23/06
Filed: 1916-09-13
Abstract: 109,118. White, A. E., (Burroughs Adding Machine Co.). Sept. 13, 1916. Adding-apparatus; operating by motors: dashpots.-In motor-driven adding-machines of the Burroughs type wherein the depression of a starting-bar closes a clutch between the constantlydriven motor shaft and the machine, as described in Specification 12083/07, the manually-operated switch is replaced by one which is closed on the depression of the starting-bar, and the motor circuit is broken after a definite interval, the delay being effected by a dash-pot or its equivalent. The knife switch 36, Figs. 2 and 4, is carried by a lever 37 which is held out of engagement by a spring-controlled catch 48 carried by a lever 66 pivoted co-axially with the switch lever 37. Upon depression of the starting-bar, the catch 48 is lifted from the projection 49 of the switch lever by the upward movement of a washer 52 on the rod 27 which is raised by the starting-bar, thus allowing a spring 46 to close the switch. A cam 53 on the motor-driven shaft depresses a spring-retracted bell-crank lever 55, to which is pivoted the pistonrod 58 of a dash-pot 60. Towards the end of the movement, a pin 70 on the lever strikes a downwardly projecting arm 71 of the lever 66 and rocks it to raise the catch 48 again into engagement with the projection 49 of the switch lever. A catch 72 engaging the lower end of the arm 71 serves to retain it in this position after the return of the lever 55 when released by the cam. Upward movement of the dash-pot piston causes the release of the arm 71 through a slotted link 77, which is carried by the piston-rod 58 and engages a pin on the catch 72. Unless the catch 48 has been lifted prior to this by the washer 52, the lever 37 is moved to break the motor circuit through the catch 48 by means of the spring 67 which overcomes the resistance of the spring 46. Hand operation 'of the machine may be effected in the usual manner by the attachment of a handle, and to prevent accidental operation by the motor, means are provided whereby, on the insertion of the handle, a slide 85, Fig. 4, is depressed, the forked end of which engages a pin 83 on an arm 81 secured to the hub of the switch lever and serves to rock and retain the switch in the open position. A handle 102 on the arm 81 projects outside the casing and allows the arm to be moved to the inoperative position and locked there apart from any action of the hand operating-device. Specification 27874/03 also is referred to.

Title: Improvements in the colouration or treatment of textile materials made of or containing cellulose esters or ethers
Filed: 1931-02-11
Abstract: Cellulose esters or ethers, dyeing; printing; aniline-black dyeing.--The penetration into fabrics made of or containing cellulose esters or ethers of substances having affinity therefor is improved by applying such substances by printing, hand-stencilling, padding or pin roll padding in conjunction with an organic liquid which is a solvent for the cellulose derivative and has a boiling point above 100 DEG  C. and thereafter evaporating the solvent without steaming. Specified solvents are ethyl lactate, diacetone alcohol, diethyl tartrate, dibutyl tartrate, benzyl alcohol and the esters or ether-esters of glycols, e.g. methyl or ethyl glycol monoacetates. The process is particularly applicable for improving the penetration of (a) dispersed insoluble colours, e.g. S.R.A. colours and those sold under the registered Trade Marks "Cellitone" and "Duranol," and (b) aromatic amines suitable for the production of anilineblacks.  It is also applicable in the production of coloured discharges either by oxidation or by reduction.  In the treatment of a delustred fabric the solvent relustres the parts to which it is applied (cf. Specification 259,265, [Class 2 (ii), Cellulose &c.].  The printing or stencilling pastes used may contain thickeners such as gum arabic, starch, British gum, soluble cellulose ethers or cellulose esters and assistants such as glycol, diethylene glycol or ethylene thiodiglycol.  The following examples are specified. (1) A fabric made of cellulose acetate yarn is printed with an aqueous paste containing a suitable dyestuff, ethylene thiodiglycol, ethyl lactate, gum arabic and colloresine, dried at 70-75 DEG  C. to evaporate the ethyl lactate, washed with lukewarm water, soaped at 50 DEG  C. and rinsed.  (2) A fabric made of cellulose acetate yarn is printed with an aqueous paste containing Diphenyl black base, aniline, ethyl lactate, glacial acetic acid and a thickener dried rapidly at 60-70 DEG  C., passed through a bath containing dilute sulphuric acid and sodium bichromate, rinsed, passed through a dilute solution of sodium carbonate, scoured in a soap bath at 80 DEG  C. and washed.  The dyeing is a very bright black, fast to rubbing.  The subject-matter claimed in Specification 360,896 is disclaimed.
