Title: Polyester resins
Inventor: NISCHK GUNTHER
IPC: C08K3/22
Filed: 1963-06-11
Abstract: A curable polyester mixture comprises a mixture of an unsaturated polyester containing ether groups and carboxyl groups which is the reaction product of an a ,b -unsaturated dicarboxylic acid component with a polyhydric alcohol component which contains from 10 to 100 mols. per cent based on the amount of said component, of a polyhydric alcohol containing oxygen-ether bridges, which polyester has an acid number of between 5 and 75, with 10 to 100% by weight, calculated on the amount of unsaturated polyester, of magnesium oxide and 1 to 6% by weight, calculated on the amount of unsaturated polyester of an organic peroxide having a decomposition half-life period at 100 DEG C. of at least 10 hours, there being no polymerizable monovinyl compound present. A polyester resin may be made from the curable mixture by heating to a temperature of 130 DEG  to 200 DEG  C. Additional ether oxygen atoms may be introduced into the unsaturated polyesters by condensation of dicarboxylic acids which contain ether groups, e.g. diglycollic acid; g ,g 1-dipropyl ether dicarboxylic acid and alkoxy-succinic acids. To increase the impact strength of the finished resin, longchained unsaturated ether dicarboxylic acids may be condensed with the above unsaturated polyesters.  In the examples the polyesters in the curable mixtures are formed from (1) diglycol, glycol and maleic anhydride; (2) 1,3-butylene glycol, diglycol, anthracene and fumaric acid; (3) dipropylene glycol and fumaric acid; (4) triethylene glycol and maleic anhydride; (5) o ,o 1-dihydroxydibutyl ether and fumaric acid, and (6) b ,b 1-di -(b -hydroxyethoxy)-butane and fumaric acid.  Sheets may be formed from the compositions and fillers added before curing.

IPC: C08F251/00
Filed: 1948-09-06
Abstract: Polymers and copolymers of vinyl esters are made by polymerizing one or more vinyl esters, with or without one or more other monomers, emulsified in an aqueous solution containing from 0.1 to 10 per cent by weight of "a water-soluble cellulose ether," i.e. any hydroxy cellulose ether or carboxy-cellulose ether, or mixture, soluble in hot and cold water without gelling, and in which the hydroxy groups of the cellulose molecule or some of them are esterified with a hydroxyalkyl compound or with a mixture of alkyl or hydroxyalkyl compounds or with carboxyalkyl compounds or salts or esters thereof. Specified esters are vinyl chloride, acetate, propionate, butyrate, and crotonate.  The other monomer may be selected from acrylonitrile, acrylic esters, e.g. methyl methacrylate, acrylic acid chloride, maleic anhydride, butadiene or vinyl alkyl ethers.  The monomers may be added to the polymerizing emulsion at about the same rate as the monomers are being polymerized and the polymerization may be carried out at a temperature between the reflux temperature and 20 DEG  C. above.  The composition may include polymerization catalysts, e.g. potassium persulphate and hydrogen peroxide, other emulsifying agents such as acids and sodium salts of sulphonated oils, alkyl sulphonates, aryl sulphonates, alkyl aryl sulphonates, alkyl ester sulphonates, e.g. sodium salt of sulphonic acid of dioctyl succinic ester, or alkyl pyridinium halides and buffering agents, e.g. sodium acetate, sodium bicarbonate, sodium monobasic phosphate and sodium pyrophosphate.
Patent GB-360058-A (GB)
Title: Manufacture of mixed cellulose esters
IPC: C08B3/16
Filed: 1930-08-05
Abstract: Organic esters of cellulose containing more than two dissimilar ester groups are formed by dissolving and digesting an organic ester of cellulose in a bath containing two or more organic acids each having an ionization constant greater than that of the acid corresponding with the starting ester, or by dissolving and digesting a mixed ester in an organic acid having an ionization constant greater than that of an acid corresponding to one of the acid groups in the mixed ester. Simple starting esters include cellulose acetate, benzoate, propionate, &c., hydrolysed or not. With cellulose acetate suitable treating acids include tartaric, racemic, malic, glycollic, pyruvic, a -keto-butyric, a -keto-valeric, a -keto-caproic, levulinic, toluic, benzoic and mandelic.  Suitable mixed esters include cellulose aceto-lactate, cellulose aceto-pyruvate or cellulose benzo-pyruvate which may be prepared as described in Specifications 338,201, 338,202, [both in Class 2 (ii), Cellulose, &c.], and 360,417.  Where necessary, the displacing acid may be dissolved in a suitable solvent, e.g. dioxane, ethylene dichloride, propionic acid, or water. A suitable temperature for the reaction is about 100 DEG  C.; but, in general, it should not exceed 150 DEG  C. to avoid degradation of the cellulose.  The multiple esters show enhanced solubility properties, e.g. esters containing both acetyl, lactyl and pyruvyl groups are soluble in acetone, in 50 per cent ethyl alcohol, in methanol and in water.  Examples are given of the treatment of cellulose aceto-lactates with pyruvic acid, and of the treatment of acetone-soluble cellulose acetate with a mixture of pyruvic and lactic acids.

Patent GB-483961-A (GB)
Title: Improvements relating to variable pitch propellors
IPC: B64C11/36
Filed: 1937-09-01
Abstract: 483,961. Screw propellers. BERLINER, H. A. Sept. 1, 1937, No. 23861. [Class 114] A variable-pitch screw propeller has a pitchvarying mechanism driven off a ring which in turn is driven by a roller from a ring on the propeller shaft, such roller being adjustable in order to obtain higher or lower speeds of the driven roller compared with the driver. A bevel wheel 9 fixed to the hub of the propeller is geared to a number of pinions 11 carried by axles 14 supported on a framework 12 connected with a fixed part such as the fuselage. The pinion 11 in turn gears with another bevel wheel on a member 15 freely mounted on the propeller hub. This member is urged by a spring 16<1> toward the blade axis, and is continued to form an arcuate friction surface 17. Freely mounted on the hub is a ring 23 having a similar arcuate surface 22 and having on its periphery a thread adapted to gear with the pinion which is on a shaft that is coupled by a pinion gearing 25, 26 to the propeller blade root. Engaging both the arcuate surfaces is a roller 18, or series of rollers, freely supported on a spindle 19 which is capable of being tilted. When the roller engages the two friction surfaces normally the rings 15, 23 rotate at the same speed and the pitch remains constant. When the roller 18 is tilted, the ring 23 is driven at a rate different from 15 and there is the resultant movement of the blade gearing 25, 26 whereby the pitch is adjusted. Tilting of the ring may be effected automatically by connecting the spindle 19 through links 27, 28, 29 with a governor 32 driven off the propeller shaft by gears 33. The governor may be adjusted by a hand cable 31 and may be uncoupled from the shaft by operation of the clutch 34 through a second hand cable 35. The pinion 26 on the blade root also gears with a rack 41 which, through a rod 38 and a ball interconnection 42, operates a member 43 connected to a pitch indicator 45. This same rod 38 carries abutments 39 which are adapted in the required extreme pitch positions of the blade to contact with a member 36 on the linkage 27, so as to return the rollers to the neutral position and prevent further adjustment of the blades. In a modification, the arcuate surfaces on the discs 23 and 15 are provided with ring grooves 52 in the position of no action so that the rollers 18 are then not in contact with the arcuate surfaces. In a modification, the contacting roller may be a plain cylindrical member contacting with reversely disposed conical surfaces, the axis of the roller being parallel to those surfaces and control being effected by sliding the rollers on its axis instead of by tilting. In a further modification, whereas the driven member remains arcuate the driving effort is obtained by prolonging the roller spindle to carry a bevel wheel which engages positively with a bevel wheel fixed to the hub.
