Title: Improvements in or relating to apparatus for the transference of designs
IPC: B41F19/06
Filed: 1959-03-07
Abstract: 867,287. Transferring designs. FORTI, A. March 7, 1959, No. 1658/61. Divided out of 867,286. Class 100(2) Apparatus for transferring designs comprising thermoplastic resins based on metallic strips to objects of thermoplastic materials comprises  a  support of regulable height for the objects, a pad of elastic material disposed on a movable arm for pressing the metallic strip against the objects, a reel with the strip wound thereon, and a reel for re-winding the strip after the designs have been transferred. A thermoplastic article 4 to be decorated is placed on an adjustable support 1, and a pedal depressed to start a motor 13 and through a cam 12 lower an arm 7, whereupon an elastic pad 2 through which cooling water flows presses a metal strip 3 carrying the design in thermoplastic resin against the article. An electric current passed through the strip above the article raises the temperature and the transfer takes place. The arm is then raised, and a cam 14 actuates a group of switches 15 to stop the motor 13 and start a motor 10 to feed the strip from a supply reel 5 towards a take-up reel 6. An electric current through the strip and a sensing element 11 is used to establish a holding circuit for the motor 10 as soon as the next design on the strip has moved away from the element 11. When the circuit is broken by the next design, the motor 10 is stopped, and the machine is ready for the next transfer.

Title: A process and apparatus for the production of ultra-pure 1,3,5-trioxane
Inventor: DANKERT GERHARD
IPC: C07D323/06
Filed: 1966-01-13
Abstract: 1,137,054. Production of pure trioxane. FARBENFABRIKEN BAYER, A.G. 13 Jan., 1966 [13 Jan., 1965], No. 1688/66. Heading C2C. Pure trioxane is obtained by distilling a mixture having a pH of from 1 to 3 of formaldehyde or paraformaldehyde, water, an acid and a trioxane organic solvent which is immiscible with water, separating out a solution of trioxane in the organic solvent from the vapours distilling over and, after the removal of the formic acid contained therein by means of an ion exchanger, separating the organic trioxane solution by fractional distillation into substantially pure trioxane and the organic solvent containing the impurities. The process is advantageously effected by distilling the initial mixture and introducing the vapours which distil over into the middle portion of a first distillation column, drawing off a substantially trioxane free aqueous formaldehyde solution from the sump of this column (which solution can be returned to the process after having been passed through an ion exchanger and optionally after having been concentrated), completely condensing in a reflux condenser the product forming at the head of the first distillation column, separating the organic and aqueous phases which are thereby formed, returning the aqueous phase to the head of the first distillation column, and feeding the organic phase containing the trioxane, after passing the organic phase through an ion exchanger into the middle portion of a second distillation column, such that the water-immiscible solvent, water and formaldehyde distil over at the head of said second column, while pure trioxane is obtained in the sump, the trioxane preferably being discharged in an inert gas atmosphere. Suitable solvents which are immiscible with water are, for example, methylene chloride, chloroform, benzene and cyclohexane. A suitable form of apparatus for carrying out the above process is described.
