Title: Process for the manufacture of fluorocarbon waxes
IPC: C08F8/50
Filed: 1958-05-14
Abstract: In a process for the manufacture of fluorocarbon waxes by the degradation of polytetrafluoroethylene (P.T.F.E.) the P.T.F.E. is heated at 300 to 600 DEG C., preferably 400-500 DEG C., in a salt melt having a melting point below 327 DEG C.  The melt may consist of a single salt, e.g. potassium pyrosulphate or an alkali metal nitrate or nitrite; or of a mixture of salts forming a homogeneous melt e.g. potassium and cupric chlorides or potassium pyrosulphate and copper or cobaltous sulphate.  Zinc chloride is not very suitable when used alone since the degradation is accompanied by carbon formation but may be used in admixture with other salts e.g. cupric chloride. Examples describe the degradation of 100 parts (by weight) of P,T.F.E. at 450 to 480 DEG  C. in the following salt melts:-(i) 170 parts CuCl2/200 parts KCl; (ii) 270 parts ZnCl2/30 parts CuCl2; (iii) 240 parts ZnCl2/60 parts FeCl3; (iv) 300 parts ZnCl2; (v) 300 parts K2S2O7; (vi) 290K2S2O7/10 parts CuSO4; (vii) 300 parts KNO3.

[Also in Divisions G3 and H2] In a photographic type-composing machine, at least two stepping motors are coupled to a common output member so that each input pulse applied to one motor produces a larger displacement than each pulse applied to another. Trains of pulses 20 for positioning output member 41 are divided by twenty-five at 21, the quotient being amplified and applied to motor 26 while the remainder are similarly applied to motor 27. The motors are coupled to the member 41 via a differential 30 whose gearing is such that each step of 26 produces twenty-five times the movement that 27 produces. As shown, the member 41 is a rack connected to mirrors 14 in apparatus for producing a line of characters on film 16 photographically from master characters 12 selected by a magnetic or punched tape programme 11. The tape controls selection of characters, spacing and point size, the latter controlling a multiplier 19 which produces the trains of pulses from information contained in a character width store 17. Alternatively, the member 41 is coupled to the lead screw of a machine tool to position a member according to a numerical value.
