Filed: 1953-07-31
Abstract: Aceituno meal (Simarouba glauca press-cake-obtained by extracting the oil from fruit kernels of Simarouba glauca by pressure) is extracted with water to obtain a new substance of formula C25H36O10 having antiamebic properties. The meal may be soaked in the water to disintegrate the cake, the mixture heated to about 70 DEG  C. with agitation, filtered and washed with hot water.  The filter cake is again extracted with water (containing if desired a small quantity of acetic acid), filtered and washed.  The filtrates and washings are combined and concentrated and any tar or gum which may separate is removed by decantation.  The liquid is further concentrated and a crystalline product allowed to separate.  The crude crystals so obtained are slurried in methanol, refluxed and filtered and the solution concentrated until crystals separate.  The crystals may be further purified by re-dissolving in methanol, filtering the solution through active charcoal and re-crystallizing.  A detailed summary of the complete procedure is given.ALSO:Aceituno meal (Simarouba glauca press-cake-obtained by extracting the oil from fruit kernels of Simarouba glauca by pressure) is extracted with water to obtain a new substance of formula C25H36O10 having antiamebic properties.

Abstract: 505,275. Shaping wood by heat and pressure. I. G. FARBENINDUSTRIE AKT.-GES. Aug. 3, 1937, No. 21391. Void. Convention date, Oct. 31, 1936. [Class 145 (i)] [Also in Group VIII] Wood is consolidated by subjecting it to the action of volatile nitrogen bases, e.g. ammonia or methylamine, if desired in the presence of organic solvents such as alcohols, at temperatures between 50 and 100‹ C. and under a pressure of at least 20 atmospheres. It may be subjected to a mechanical treatment while in the swollen state. Removal of the base may be effected by evaporation at atmospheric or reduced pressure. The wood may be treated with impregnating agents, e.g. waxes, oleic acid, urea and triethanolamine during the action of the bases or before or after their removal. While in the plastic state it may be bent, pressed between flat plates or in moulds or separated into fibres and pressed. Prolonged mechanical treatment e.g. by calendering, converts the wood into a flexible product similar to leather, which may be impregnated with rubber emulsions or emulsions solutions or melts of plastic condensation or polymerization products, e.g. polyvinyl chloride. The surface may be dyed or coated with lacquers. Examples 'describe the treatment of oak and ash with liquid ammonia or methylamine.
Patent GB-214591-A (GB)
Abstract: 214,591. Friedrichs, W. April 19, 1923, [Convention date]. Franking-machines.-In feeding letters in postmarking and franking-machines, effective feed is ensured by providing means for reciprocating the machine table which permit the table to accommodate itself for the thickness of the letter presented. Counter-pressure rollers 6, coacting with a stamping roller 1 and feed rollers 2, are spring- mounted in a table 3 attached to a plate 4 slidable in vertical guides 5. The table is depressed by means of a cam 21 engaging a lever 19 pivoted at 18 and jointed to an arm 16 connected by a pin 14 and slot 15 to a member 13 fixed to the plate. 4, and is raised by springs 11 connected at one end to a stationary member 12 and at the other to a bar 10 fixed to the plate 4. The height to which the table 3 rises is limited by the thickness of the letter, the pin and slot allowing additional motion of the arm 16 under the action of a spring 22. A pin 23 on the arm is caused to engage during the additional movement one arm of a bell-crank 24 mounted on the plate 13 so that a tooth 26 on the other arm engages a rack 27, thus preventing further rising of the table 3 when the letter is released. In the case of a succession of thin letters, the mechanism may be put out of action by disconnecting the drive to the cam shaft 31, a rod 33 being simultaneously moved to the left to prevent the tooth 26 from engaging the rack.
