Patent GB-482400-A (GB)
Title: Improvement in adhesive layers and their production
IPC: C09J161/14
Filed: 1937-02-08
Abstract: Adhesive layers are prepared containing hardenable alkali metal derivatives of phenolaldehyde condensation products, if desired in admixture with natural resin soaps, softeners such as oils, fats or glycerine or thickeners such as carbohydrates, or precipitation products thereof.  Adhesive layers include thin sheets such as veneers coated with the adhesive or sheets of paper or fabric coated with the adhesive.  The alkali metal derivatives are the products obtained by treating substantially condensed phenols and aldehydes with an alkali.  The condensation products may be precipitated on the surface of the layer by treatment after applying the alkali metal compound with a precipitant such as a metal salt solution, dilute acid or solutions of resins immiscible with water or by applying the alkali metal compound to a layer pretreated with the precipitant. The alkali metal derivatives are applied to the layers by any known glue-spreading process and the products used in the manufacture of multi-ply products.  In examples the alkali metal derivative is prepared by condensing cresol and aqueous formaldehyde in the presence of a condensing agent such as hexamethylenetetramine, soda, oxalic acid or salicylic acid until the product separates into two layers, removing and drying the condensate and heating with aqueous caustic soda to obtain a solution.  The product may be used alone to treat peeled veneers which are then laminated before or after drying; to treat paper, fabric or other absorbent material for use wet or dry between layers of wood and wood, wood and asbestos-cement composition or wood and metal (the metal if desired being also treated) in the preparation of laminated materials; to treat veneers in association with treatment with a precipitant.

Abstract: 112,547. Imray, O., (Bosch Magneto Co.). March 17, 1917. Magneto-electric machines for igniting in mul. tiple-cylinder internal-combustion engines. To produce four or more flux changes per revolution of the armature, two or more magnets 6, 7 are arranged side by side with the long limb of one magnet adjacent the short limb of the other so that the pole-shoes 8<1>, 8<11>, 9<1>, 9<11> are displaced circumferentially around the armature 2; the pole shoes have the same axial width as their respective magnets so that the fluxes are kept separate. The magnet 6 is wider than the magnet 7 so that it may surround the armature cover 15 and condenser. An interrupter 11 with four cams and a distributor 16 are mounted on the armature shaft; a brush 14 engaging the cover 15 connects the armature core with the magnet frame. To prevent flux leakages, the magnets may be separated by non-magnetic material 20 and the armature core may be in two parts separated by non-magnetic material 19. In a modification for producing six impulses per revolution, three magnets are arranged side by side with their pole-shoes 60 degrees apart. Fewer sparking voltages may be obtained per revolution by providing fewer cams on the interrupter. Distributors of the ordinary type, or main and auxiliary distributors, may be employed.

Title: Process and device for further preparing cocoa-beans after fermentation
IPC: A23G1/02
Filed: 1929-02-08
Abstract: 329,015. Muller, B. Feb. 8, 1929. Cocoa manufacture.-A process for the preparation of cocoa beans after the alcoholic fermentation comprises subjecting the beans to a heating process in a stagnated atmosphere in a closed room at a temperature not exceeding 50‹ C. to produce a swelling of the beans and a loosening of the tissues, the beans being then subjected to a drying process in the same room by a stream of dry air at a temperature not exceeding 60‹ C. whereby the internal moisture of the beans is expelled. During the drying of the beans, the internal fermentation of the beans is stated to continue. The beans are then subjected to continuous ventilation in another chamber until required for use or shipment. The beans after an alcoholic fermentation are stacked in trays b in a drying chamber a provided with vertical shafts c for circulating dry air forced from a heating chamber f through a channel d and pipes g by a fan c. The beans are first warmed to the desired temperature by heating pipes, the air inlet and air outlet being throttled and the valve l remaining open only slightly to permit the moist vapours to increase in the chamber. After the beans have assumed the requisite bulgy swollen shape, the valve l is opened wide and a continuous pre-warmed stream of air swept through the chamber until the beans become uniformly brown and lose their bitterness. This operation may be completed by using the outside warm air admitted through a valve q in a pipe p, the valve o being then closed. The beans are stacked in wooden trays b permeable by the air and arranged on portable frames arranged on trollies, as shown. The beans are dried subsequently and stored in a receptacle s, Fig. 3, in which pipes t made of wooden laths are supplied with fresh air by means of a fan n, regulating slides v being provided on the frant wall of the receptacle. The fan is also employed to remove by suction through the pipes w the moisture which may have collected in the chamber, the slides v then being open.

Title: Improvements in the manufacture of cellulose esters
IPC: C08B3/12
Filed: 1953-02-20
Abstract: A dicarboxylic acid ester of cellulose or of a cellulose derivative is obtained by treating the cellulosic material under substantially anhydrous conditions with a dicarboxylic acid anhydride in the presence of a lower aliphatic carboxylic acid, containing 1-4 carbon atoms in the molecule, as solvent and of an acid-soluble salt which exhibits basic properties in non-aqueous solution.  The cellulosic material may be cellulose, a cellulose ether or a cellulose ester. The anhydride may be phthalic, nitrophthalic, succinic or maleic anhydride, and the acid-soluble salt may be an acetate of an alkali metal, alkaline-earth metal or organic amine.  It may be sodium, potassium, ammonium, calcium, magnesium, methylamine or pyridine acetate, or trisodium phosphate.  The proportion of the salt may be within the range of 5-350 per cent by weight of the cellulosic starting material. The esterification may be carried out at 60 DEG C. up to the reflux temperature of the reaction solvent. Precipitation of the ester may be effected by adding sufficient water to the reaction mass to cause precipitation at 55-95 DEG  F.  The solution may be neutralized, before precipitation, by the addition of an acid such as hydrochloric or sulphuric acid.  In an example, regenerated cellulose is soaked in water and then the water is removed by means of glacial acetic acid.  The cellulose impregnated with acetic acid is introduced into a bath containing acetic acid, pyridine acetate and phthalic anhydride.  The mixture is maintained at 100 DEG  C. until the cellulose has dissolved.  The cellulose phthalate formed is precipitated by pouring the solution into acidulated water.  In another example, cellulose acetate containing free hydroxyl groups is mixed with phthalic anhydride, sodium acetate and propionic acid.  The mass is heated on a steam bath for 6 hours and the product is precipitated from the solution by the addition of water.  Butyric acid or acetic acid may be used as solvent instead of propionic acid.  In other examples, the starting material is ethyl cellulose containing free hydroxyl groups and it is reacted with nitrophthalic anhydride, succinic anhydride or maleic anhydride in presence of sodium acetate and acetic acid.
