Filed: 1934-05-11
Abstract: 438,359. Filters ; softening water. ELECTROLUX, Ltd., and HAFNER, J. C., Luton, Bedfordshire. May 11, 1934, No. 14291. [Class 46] [See also Group XXIX] A portable filter or water softener of the base-exchange type is provided with a valve which enables water from the main supply to pass directly to the outlet of the apparatus when only unfiltered or hard water is required or to be mixed in any proportion with water which has passed through the apparatus. In one position of the valve the water is caused to pass entirely through the apparatus but in no position is the outlet closed. The filter or softener is thus never subjected to the full pressure of the water in the main. Fig. 2 shows a portable water softener in which the valve 21 is in a position to cause all the water from the main supply 20 to enter the inlet pipe 11 of the softener, the softened water passing through the pipe 12 to the outlet 18. Fig. 4 shows the position of the valve in which no water passes through the softener, the main supply being diverted entirely into the outlet 18. In an intermediate position of the valve a part of the main supply passes directly to the outlet 18 and a part enters the softener and is discharged through the pipe 12 and mixes with the unsoftened water in the outlet 18.

Title: A new manner of and apparatus for ascertaining the mean length and/or the mean weight per unit of length of cotton or like fibres
IPC: G01N33/36
Filed: 1934-05-14
Abstract: 420,960. Measuring the mean length and/or mean weight per unit length of cotton or like fibres. INDIAN CENTRAL COTTON COMMITTEE, Vulcan House, Nicol Road, Ballard Estate, Fort, Bombay, India. May 14, 1934, No. 14513. Convention date, May 19, 1933. [Class 120 (iii)] The mean fibre length of raw cotton or other textile fibres is obtained by taking a representative sample of the fibres, combing it out, selecting therefrom a bunch of fibres with aligned ends, cutting off a measured length from the aligned end and from the centre by dividing the bunch at two points and thereby forming three groups, calculating the average length of the uneven ends in the third group by comparing its weight with the weight and known length of the fibres in the first group and adding the calculated length to the known length of the first and middle groups to give the mean length of the fibres in the bunch. A sliver of the cotton under test is engaged in the combs 1 and a number of groups of fibres are nipped by the jaws 5 of tweezers 3 having springs 3<a> and supported on a slide bed 4 and are thereby withdrawn from the sliver and discarded until all the projecting ends are in alignment. A test sample bunch is then detached and stray fibres removed by combing. The screw 7 is then released and the tweezers rotated through 180‹. The projecting ends are now gripped by the tweezers 14 on the carriage 8 and the latter moved back until the fibres are straightened over the bridge piece 9. The cutter 12 comprising blades 11, 18 separated by a distance piece 19 is then lowered by the handle 17 to cut the bunch of fibres into three portions. The length of the first portion is read on a vernier scale while the width of the plate 19 is known. The three portions are then weighed and the average length of the fibres in the third group calculated by comparison with the readings of the first group, thus avoiding any inaccuracies due to the fibres being thicker at about the middle of their lengths. If desired the mean fibre weight per unit length may be found by dividing the total weight by the number of fibres and the ascertained mean length.

Abstract: 577,840. Extractive distillation of hydrocarbons. SHELL DEVELOPMENT CO. Sept. 6, 1943, No. 14594. Convention date, Aug. 14, 1942. Drawings to Specification. [Class 32] Two unsaturated hydrocarbons with close boiling points but different degrees of unsaturation are separated by subjecting a hydrocarbon mixture containing them to an extractive distillation with a solvent which does not form constant boiling mixtures with the components of the mixture; the distillation being conducted under superatmospheric pressure, e.g., between 4 and 8 atm., when the solvent is selective for the lower boiling of the two hydrocarbons to be separated, and under subatmospheric pressure, e.g., between 760 and 200 mm., when the solvent is selective for the higher boiling hydrocarbon. Butadiene (b.p.-4.5‹C.) and cis beta butylene (b.p.+3.73‹C,), present in narrow boiling fractions predominating in hydrocarbons of four carbon atoms, may be separated by distilling the fraction under superatmospheric pressure in the presence of a solvent selective for butadiene; but by distlling at a reduced pressure when a solvent is employed which is selective for cis beta butylene. In the first mode of operation butadiene is recovered upon regeneration of the solvent, in the second it is obtained as overhead during the extractive distillation. The separation of butadiene from alpha butylene is also referred to. A non-polar solvent is employed when the hydrocarbon to be extracted is more saturated than the other component, while a polar solvent, to which water may be added, is used in the separation of diolefines from mono-olefines. Lists of non-polar and polar solvents suitable for use in the process are included in the Specification.
