Title: A process for the production of esters from olefines
IPC: C07C51/14
Filed: 1934-09-01
Abstract: Esters are produced by reacting a carboxylic acid in the presence of a condensing agent such as sulphuric acid with an excess of olefine or olefinic mixture containing organic compounds capable of acting as solvents for the ester formed, then allowing the reaction mixture to stratify without addition to or dilution of the mixture, and recovering ester from the solvent phase. Suitable olefines are ethylene, propylene, butene-1, butene-2, secondary amylenes and hexylenes and mixtures thereof; mixtures of olefines and paraffins are particularly suitable.  Preferably mixtures obtained by condensation or cracking are first fractionated so as to obtain fractions containing the same number of carbon atoms, such as butane and butylene or pentane and amylene.  Tertiary olefines and diolefines may be selectively removed from the initial mixture before use, for instance by polymerization, sulphonation, etherification with an alcohol (see Specification 393,753), chlorination, hydrochlorination, solvents, &c.  Suitable carboxylic acids are acetic, propionic, butyric, isobutyric, benzoic, succinic, and a -chlorpropionic acids, and the condensing agent may be zinc chloride, benzene sulphonic acids and their homologues, alkyl hydrogen sulphates, sulphoacetic acid, or chlorsulphonic acid.  Examples describe the treatment with acetic and sulphuric acids of a mixture containing amylenes and pentane, and of a mixture containing propylene respectively.

IPC: G03B35/00
Filed: 1958-08-13
Abstract: 897,363. Optical projection systems. HARRIES TELEVISION RESEARCH Ltd. Aug. 12, 1959 [Aug. 13, 1958], No. 26040/58. Class 97(1). In an optical projection system for projecting a two-dimensional image of an object on to the surface of a three-dimensional model of the same object, there is provided in the light path to the model a device having at least one surface which varies in slope and comprises several facets separated by lines of discontinuity of slope, the gradient of each facet being chosen to displace the points of arrival of the rays at the surface of the model by the amounts necessary to correct keystone distortion. This device which is described in the Specification 897,361 may also correct for pincushion and barrell distortions and, by giving each facet a lenticular surface, for defocusing. Focus may also be improved by providing for the mounting surface (e.g. film, transparency or television phosphor) or upon which the two-dimensional image is produced to be curved or tilted about the optical axis. As shown in Fig. 1, a cinematograph film 11 bearing coloured images of a person's face, is projected through a correcting element 15 on to the back projection screen 10 having part thereof in the form of a three dimensional model of the same person's face. In this way different combinations of, for example, cosmetics and hair colouring can be demonstrated. The film may have a synchronized sound track and there may be a loud-speaker 24 fed from a pick-up 23. In another form, several projectors, each with a keystone distortion correcting device, project images from different directions on to the single three dimensional model, the projectors operating synchronously (Fig. 3, not shown). Television projectors may be used instead of cinematograph projectors, in which case the video signals supplied to the projectors, the audio signal supplied to a loudspeaker and the synchronizing signals and scanning pulses may be provided by tape recorder. The model may also be moveable in synchronism with movements which appear successively in the two dimensional image which is projected thereon; alternatively, the projector may move in simulation of the camera movement during recording of the two dimensional image. The model and the two dimensional image may be produced from the same object, in which case the movements of the model may be made to follow those by the object as by servo mechanisms and recording tape.

Title: Process for treating cellulosic raw materials
IPC: D21C1/02
Filed: 1946-08-29
Abstract: The process of the parent Specification in which cellulosic raw material is treated with water under pressure in an autoclave at a temperature ranging from 160-210 DEG  C. to obtain a cellulosic pulp and a solution containing organic matter including sugars, is modified in that the duration of the treatment is between 1 1/2 and 4 1/2 hours at 160 DEG  C., and the temperature of treatment and duration are so related that for each 10 DEG  C. rise above 160 DEG C. the time is reduced by at least one half.  Within these conditions, the intensity of the treatment may be varied according to the nature of the raw material and the nature of the products to be obtained.  The amount of water present must be sufficient continuously to immerse, sprinkle, or wash the cellulosic material, so that in addition to the pulp there is obtained a solution containing sugars and other organic matter. For obtaining pulp suitable for making cardboard, straw may be treated with water at 160 DEG  C. for 3 hours, at 170 DEG  C. for 1 1/2 hours, or at 180 DEG C. for 1/2 hour.  Green phragmites may be treated at 170 DEG  C. for 50-60 minutes; ripe yellow phragmites would require 1 1/4 -1\ba1/2 hours at the same temperature to produce similar pulp and old phragmites cut after the winter would require 1 3/4 -2\ba1/4 hours. If desired, the spent liquor may be used for treating a further quantity of raw material.  Wash-water recovered from the washing of the treated material may also be utilized.  In both these cases, the time of treatment may be reduced.  The time may also be reduced by adding a very small proportion of acid to the treating water, the pH being adjusted to a value which must be higher than 2.5 before the treatment.  Sulphuric, hydrochloric, nitric, phosphoric, acetic, oxalic, formic, or citric acid may be added. In the case of strong acids the normality should be less than 1/100 and in the case of weak acids it should not be more than 2/10.  Straw may be treated for 30 minutes at 175 DEG  C. with acidified water equivalent to 1/250 normal sulphuric acid.  The pulp obtained gives a paper of good strength.  Sodium or calcium phosphates may be added to the water instead of acids.  The acidity of the treating water may be controlled or reduced by the addition of neutralizing salts such as calcium carbonate.  The materials may be pretreated with hot water. Following the main treatment, the cellulosic products may be malaxated with milk of lime, and may be bleached with calcium hypochlorite solution. Specification 19621/07, [Class 5], is referred to.
