Title: Process for the detoxication of the tubercle bacillus and other germs, for the preparation of vaccines
IPC: A61K39/02
Filed: 1920-01-23
Abstract: 161,341. Thomson, D. Jan. 23, 1920. Vaccines.-Non-toxic vaccines are prepared from germs by separating the alkali-, acid-, and alcohol-soluble portions by successive precipitations. Tubercle bacilli, gonococci, or Pfeiffer bacilli are treated with an alkaline solution and the solid residue removed. The solution is treated with acid, and the resulting precipitate is neutralized and then treated with alcohol to form a precipitate A. The acid solution is treated with alcohol to yield a precipitate B. The residue of the germ substance not soluble in alkali is treated with acid, and the solution obtained is rendered alkaline to give a precipitate C, and then treated with alcohol to give a precipitate D. The residue of germ substance not dissolved by the alkali or bv the acid is treated with alcohol to give a solution from which a precipitate E is obtained by the addition of salt solution, and the final residue of germ substance is treated with chloroform to obtain an extract which is evaporated to dryness and washed with alcohol to yield a residue F. The substances A, C, E, and F, with or without Band D, are emulsified with normal saline solution and standardized for use as vaccines. Specification 136,036 is referred to.

Title: Improvements in apparatus for applying cigar, cheroot or the like wrappers
IPC: A24C1/30
Filed: 1933-01-26
Abstract: 396,631. Cigar-making machines. KJAER, J. W., 1A, Morlenesvej, Holte, Denmark. Jan. 26, 1933, No. 2510. Convention date, Jan. 26, 1932. [Class 130.] Wrappers are conveyed by suction or other holders 86 mounted on a wheel 85, and applied by the rotation of rollers 42, 43, 82. The bunches are advanced between a belt 8 and an overlying plate 14, the rollers 42, 43 beipg alternately lifted as the bunch is required to pass between and the wrapped cigar beyond them. The band 8 rune in a bed half-cigar shaped in transverse section, the smooth roller 82 providing the complementary halfshape during rolling and wrapping. Each conveyer 86 is mounted rotatably on a hollow pin 88 projecting radially from the shaft 85; its face conforms to the cylindrical shape of the " wheel," and is wrapper-shaped. The sleeve 87 secured rigidly to the holder 86 but rotatably to the pin 88 by a union 92 carries a toothed wheel 94 engaged by a sector 95. Linkwork renders the movements of the sector responsive to the form of a fixed cam-ring 104. As the shaft 85 rotates to bring the end of one of the holders 86 over the roller 82, the engagement of the sector 95 and pinion 94 causes the rear end of the holder to be swung outwardly. A resilient needle 107 acting in conjunction with the notch 106 presses the end of the wrapper against the roller 82. As the wheel 85 rotates the pressed end is slipped between the rollers and wrapping proceeds as the leaf is peeled from the holder 86. The swinging movement of the holder produces the requisite helical winding and tucking of the ends. If the mouth tip of the cigar is similarly shaped to the bunch top shown, the top of the holder is formed with a lug similar to the lug overlaid by the part 109, and during the wrapping of the tip the wheel receives an axial displacement. In wrapping cylindrical cigars the swinging arrangements for the holders are omitted. Specification 382,207 is referred to.

Title: Improvements in or relating to the interchange of heat between liquids
IPC: F28C1/02
Filed: 1925-01-30
Abstract: 251,344. Soderlund, O., Gram, T., and Techno-Chemical Laboratories, Ltd. Jan. 30, 1925. Liquids, treating with gases.-Heat is transferred from one liquid to another by circulating a mixture of gas and vapour between a hotter and a cooler chamber so that the amount of the gas is varied in order to maintain a more or less constant temperature difference between itself and the liquid, the volume of gas passing different temperature regions of a chamber being varied in accordance with its heat-carrying capacity. Two vertical 'towers a, b filled with transverse plates on edge and spaced apart are connected by ducts, and the tower a is traversed by a hot liquid to be cooled; this liquid at a temperature of 90‹ C. enters by a pipe a<2> and leaves at a temperature of 50‹ C. by a pipe a<3>. The cold liquid to be heated is supplied by a pipe b<2> at a temperature of 40‹ C. and is withdrawn by a pipe b<3> at a temperature of 80‹ C. A fan c draws the gaseous medium from the top of the tower b through duct b<1> and delivers it to the bottom of the tower a. This medium rises in tower a absorbing vapour from the hot liquid and passes by ducts d, d'. d<2> , a<1> which connect the parts of the towers of corresponding temperatures to tower b wherein the vapour is condensed in stages. In one modification, each tower can be divided into two sections of different crosssectional area. In another modification, in which liquid such as a colloidal solution is heated at high temperature for destroying its slimy properties, the process is carried out in apparatus comprising a warm and cool tower situated side by side, and a warm and cool tower arranged one above the other; the lower temperature exchange takes place at atmospheric pressure, and the higher temperature exchange in the superimposed towers is under increased pressure.
