Title: Improvements in or relating to the separation of rosin acids from rosin and tall oils
IPC: C09F1/00
Filed: 1947-11-20
Abstract: Rosin acids are separated from rosin or tall oil by dissolving in an organic solvent in which rosin acids are soluble but their cyclohexylamine salts are not, treating the solution with cyclohexylamine and separating off the salt at a temperature at which it is solid, e.g. room temperature.  Specified solvents are naphtha, mineral spirits, petroleum ether, acetone and alkyl alcohol white the concentration of rosin in the solution preferably varies up to 40 per cent.  The material to be treated may comprise disproportionated rosin or pine oleoresin and the separated salt may be hydrolysed, e.g. by means of hydrochloric or sulphuric acids to give pure rosin acids.  The process is particularly applicable to the separation of the rosin acids and fatty acids in tall oil.  Specification 652,370 is referred to.

Abstract: 465,888. Glass manufacture. DICHTER, J. Nov. 15, 1935, No. 31722. Convention date, Nov. 15, 1934. [Class 56] Relates to the manufacture of small bottles or vials from glass tubing by a machine of known type in which uniform lengths of tubing 2 are conveyed transversely past a number of heating and shaping devices. According to the invention, the machine is provided with a device for automatically turning each tube end for end during its passage through the machine so that one end of each tube is shaped in one series of operating stations I-V while the other end is shaped in a second series of operating stations I<1>-V<1>. The glass tubes 2 enter the machine from a receptacle 1 and are conveyed stepby-step by means of transfer bars 3. In the working-positions, the tubes rest on and are rotated by pairs of rollers 4, and the axes of the rollers may be inclined to the horizontal in order that the tubes may be kept in contact with an abutment. The same result may be obtained by making the outer rollers of slightly larger diameter than those nearer the abutment. When a tube with one end shaped leaves position V, it is received on a trough 6 which is raised and is then rotated horizontally through 180‹ to turn the tube end for end. After the trough is lowered, the tube is conveyed past positions I<1>-V<1> with its shaped end in contact with the abutment while the other end is heated and shaped.
