Title: Process for the working up of mixtures containing vinyl ethers of aliphatic or cycloaliphatic alcohols containing four or more carbon atoms and these alcohols themselves
Filed: 1955-05-10
Abstract: Vinyl ethers of aliphatic or cyclo-aliphatic alcohols having at least 4 carbon atoms are separated from mixtures containing the vinyl ethers and the alcohols themselves by subjecting the mixture to an elevated temperature in admixture with substantially sufficient of an alkali metal alcoholate of an alcohol which contains per molecule fewer carbon atoms than, has a lower boiling point than and does not form an azeotrope with the higher alcohol component of the initial mixture, in solution in the alcohol of lower boiling point, to convert the higher alcohol to its alkoxide and then distilling off the lower-boiling alcohol present and formed in the reaction and finally a vinyl ether fraction substantially free from the corresponding alcohol.  The ether mixtures treated may be those formed by reacting the higher alcohols with acetylene in the presence of an alkaline catalyst. The alcoholate of the low boiling alcohol may be used in excess up to about 20 per cent of theory.  In examples: (1) an azeotrope of n-octyl vinyl ether with n-octanol is heating while methanolic sodium methylate is added; methanol is distilled off and thereafter the residue is distilled in vacuo to recover pure n-octyl vinyl ether from a residue of the sodium alcoholates of octanol and methanol, which residue is dissolved in water, neutralized and the octanol recovered; (2) the azeotrope of 2-ethyl-n-hexyl vinyl ether with 2-ethyl n-hexanol is separated in like manner; (3) a ternary mixture of 1-methyl-n-heptyl vinyl ether, methyl n-hexyl ketone and 1-methyl-n-hexyl carbinol is treated as in (1) yielding a final distillate of vinyl ether containing substantially no alcohol, but which contains the ketone which may be removed by conversion thereof into its oxime; (4) the azeotrope of cyclohexyl vinyl ether with cyclohexanol is treated as in (1) and the recovered vinyl ether fraction (98 per cent pure) is retreated in the same manner for further purification.  The mixtures of isoamyl vinyl ether, hexyl vinyl ether, ethyl butyl vinyl ether, dodecyl vinyl ether and cetyl vinyl ethers with the corresponding parent alcohols may be separated in like manner.

Abstract: 779,962. Dipsticks. MARTIN, R. B., and WHITING, B. T. May 10, 1956 [May 10, 1955], No. 13451/55. Addition to 729,849. Class 123 (1). In a dipstick 4 which extends coaxially of a carrier 1 and sleeve 2 and is retained in its retracted position, Fig. 1, by a compression spring 8 disposed between a shoulder 7 at the lower end of a tubular extension 6 of the stick and the bottom of the carrier 1, as described in the parent Specification, the stick is secured in its depending operative position by a pawl 13 which is pivoted at the inner end of a plunger 10 projecting from the upper end of the tube 6. Normally the pawl 13 extends through a slot 17 in the wall of the tube 6, under the action of a spring-pressed piston 15 slidable within said tube, but when the stick is depressed, relatively to the carrier 1 and sleeve 2, into its operative position, the pawl, after passage through a nut 3 at the upper end of the carrier 1, will be projected through said slot 17 into engagement with the underside of the nut. Disengagement of the pawl 13 and nut 3, to permit retraction of the stick, is effected by depressing the plunger 10, Fig. 3, within the tube 6. The lower end of the stick has a flat graduated face 5 and, similarly, the bore of the lower end of the sleeve 2 is of D- section.
Patent GB-134865-A (GB)
IPC: H01C10/02
Abstract: 134,865. Brown, S. G. Aug. 13, 1918. Microphones and variable-resistance transmitters; telephonic non-contact-making re ays.-An electrolyte is divided into two portions each containing an electrode, 3, 4, Fig. 1, by an insulating partition 5 having a constricted passage 6, the flow of the current through which is varied, for example by a valve 9 operated by the diaphragm 7 of a telephone transmitter. The valve 9 is bored at 10 to form an air cushion. The diaphragms 7 may transmit vibrations directly, or through a rod and second diaphragm, to the electrolyte and may constitute one electrode, the disturbance set up in the liquid varying the resistance. In the form shown in Fig. 4, the diaphragm 41 forms one wall of a passage through which current passes between electrodes, the other wall being formed by a rigid corrugated surface 43. Rubber tubes 44 are arranged in the corrugations to form air cushions. The device may be operated electromagnetically so as to form a relay. The electrolyte may be copper sulphate with copper electrodes, mercury nitrate with mercury electrodes, or other combination in which no change in chemical constitution takes place, and no gases are generated on passage of current. Alternatively, electrodes and electrolyte may be employed in which a reversible change takes place, in which case the direction of the current is reversed at intervals. Or the electrodes of an accumulator may be used. The resistance may be varied by the heat generated by the passage of the electrolyte through small holes. The flow of the current may alternatively be affected by a variable magnetic field. The pressure on the surface of the liquid may be registered by the alterations caused in the current. Instead of speaking directly against the diaphragm a telephone receiver may be employed, enabling the instrument to be used as a telephone relay. The invention may be applied to the detection of submarine sound waves. According to the Provisional Specification, a vertical strip of material may be movable transversely to act as a shutter and vary the size of the opening in the diaphragm, and may be moved by being connected to the movable coil of a siphon recorder.

Title: Improvements in or relating to the purification of sugar-beet diffusion juices
IPC: C13B20/06
Filed: 1963-04-05
Abstract: In a process for purifying sugar-beet diffusion juice comprising defecation with lime and intermediate, main and final carbonations, and filteration or sedimentation, a predetermined amount of the calcium carbonate precipitated during final carbonation to about pH 9.0 is mixed with the diffusion juice to render it stable.  The stabilized juice is then mixed with 500 to 1000% of its weight of unfiltered juice from subsequent main carbonation, and the mixture is briefly oversaturated with carbon dioxide gas to bring its pH below 10.  An amount of lime equivalent to 1.0 to 1.5% CaO, computed on the weight of sugar-beet, is added to the oversaturated mixture, which is then carbonated approximately to pH 10.8, to precipitate colloidal impurities.  The resulting mixture is then filtered. An amount of lime equivalent to 0.5 to 1.0% of GaO, computed on the weight of sugar-beet, is mixed with the filtrate, which is then warmed and subjected to intermediate carbonation to a pH between 10.8 and 11.4, so that colour and non-sugars are removed.
