Title: Lower alkanols as aids in surface active agent recovery
IPC: C11B1/10
Filed: 1973-04-30
Abstract: 1394139 Recovery of surface active agents from aqueous solvents PROCTER & GAMBLE CO 30 April 1973 [1 May 1972] 20379/73 Heading C2C [Also in Division C5] A surface active agent is isolated from an aqueous solvent by adding sufficient of a monohydric C 2 -C 7  alkanol to form an azeotropic mixture with the aqueous solvent, and removing the azeotropic mixture by evaporation or distillation, leaving the surface active agent isolated. The surface active agent may be a detergent, e.g. the sodium salt of a fatty acid, a wetting agent, e.g. a soap or alcohol, or an emulsifier, e.g. a monoglyceride. The invention is exemplified by a preferred extension of the process for the isolation of a monoglyceride from a mixture of glycerides, as follows: the glyceride mixture is subjected to liquid/liquid extraction (countercurrent) between aqueous solvent (90% methanol) and an alkane (hexane or pentane), di- and tri-glycerides being removed with the alkane and the monowith the wet methanol; the alkanol may then be added to the monoglyceride/wet methanol solution for azeotropic separation as above, but in practice much of the solvent is distilled or evaporated off before adding the alkanol (n-butanol, sec-butanol, npropanol or isopropanol) and taking off the azeotrope to isolate the monoglyceride.

Abstract: 1468927 Testing rod-like articles HAUNI-WERKE KORBER & CO KG 9 May 1974 [12 May 1973] 20410/74 Heading A2C Apparatus for inspecting rod-like articles of the tobacco-process industry comprises a rotary drum conveyor 40 with holders 41 for receiving articles 42 with their axes at right angles to the direction of conveyance, and including at least at one side thereof sealing means 64 for sealing engagement with a respective end of each article while permitting a negative or positive air pressure to be applied, the sealing means being carried rotatably about an axis inclined with respect to the axis of rotation of the conveyor 40 so as to cause relative movement together and apart during rotation. As shown in Figs. 2 and 3 articles 42 are deposited by an intermediate drum 29 in recesses 38 at the instant when inspection rings 58 have moved apart and away from conveyor 40 owing to their inclined position. During rotation of conveyor 40, when the inspection rings 58 are entrained by the coupling pins 74, the latter move towards each other so that the sealing means 64 act upon the ends 71 of the articles 42 with the required sealing pressure. In this position inspection air which leaks and alters the reading on gauge 78 is indicative of an unsatisfactory wrapping.

Abstract: 419,620. Embossing celluloid or similar sheets. MICHAEL, A., Landhaus, Heideck, near Eilenburg, Germany. July 20, 1933, No. 20511. Convention date, July 21, 1932. [Class 100 (ii).] Celluloid or similar material is embossed while plastic, with a surface pattern, e.g. imitating the grain of leather, by means of a matrix made of paper, fabric, or similar thin material which has previously been impressed with the required pattern. The matrix may be coated on its embossing face with gum arabic or other readily soluble substance so as to prevent it adhering to the celluloid, or a paper sheet coated with the substance may be interposed between the celluloid and the matrix for the same purpose. A filling of gypsum mixed with glue or woodmeal may be applied to the back of the matrix so that it presents a flat surface to the pressureproducing device. Also, a dressing of casein may be applied to the matrix to prevent it from being flattened when pressed against the celluloid. When the matrix is made of fabric, it is impregnated with starch and kaolin to obliterate the pattern of the fabric. A number of celluloid plates with matrices between them may be placed in a press and embossed simultaneously. The softening of the celluloid may be effected by heating or by the application of solvents such as amyl-alcohol, amyl-acetate, acetone; or alcohol.

Filed: 1943-12-16
Abstract: 573,650. Adjustable seats. WRIGHT, R. N. Dec. 16, 1943, No. 21088. [Class 52 (ii)] The under frame 31 of a seat is supported by crossbars 17, 18 engaging in slots 32 therein, the slots 32 allowing for horizontal sliding adjustment, the crossbars 17, 18 being vertically adjustable in vertical slots 16 in uprights 11 &c. to get vertical or tilting adjustment. One, or both, of the crossbars 17, 18 are adjusted up or down by moving them endwise against the pressure of springs 33 thereon so that cross pins 24, fixed in the crossbars, can be moved from one to another of notches or depressions 25 in the sides of the slots in the uprights 11 &c. The horizontal position is locked by projections 44 on a lever 43 carried by the ends of both crossbars 17, 18 the projections fitting into the required holes 45 in the sides of the frame 31, the lever 43 being movable outwards by hand against spring pressure to disengage. The axial movement of the crossbar 17, 18 to allow vertical or tilting adjustment may be effected by a hand lever 35 pivoted at 37 to a plate 38 secured to the crossbar 17. The plate is slotted at 39 to receive a pivot 36 on the crossbar 18. Movement of the lever 35 in one direction causes it to pivot about 36, the crossbar 18 being unable to move axially in one direction, whereby the pivot 37 is moved to one side carrying with it the plate 38 to which is attached the crossbar 17. Movement of the lever in the other direction causes the lever to pivot about 37 and as the crossbar 17 is unable to move axially in that direction, the crossbar 18 is moved axially to free the pins 24 from their depressions and allow vertical adjustment. In a modification the frame may be located below the floor of a vehicle, and the upright would be adjustable and be attached to the seat.
