Patent DE-2004643-A1 (DE)
Title: Diammonium terephthalate purifn
IPC: C07C51/42
Filed: 1970-02-03
Abstract: Disporportionation of PhCO2K and isomerisation of C6H4(CO2K)2 gives crude diK terephthalate which on addn. of NH3 and CO2 or (NH4)2CO3 crystallises out di NH4 terephthalate. This is dissolved in water, insoluble impurities are filtered and pure diNH4 terephthalate crystallises on addn. of NH3 and CO2. The 2nd batch is recycled with the 1st stage product. Excess NH3 and CO2 are thermally desorbed from the mother liquors and reused, and the soln. containing K + is used to prepare PhCO2K and C6H4(CO2K)2 for subsequent conversion to di-potassium terephthalate. This is a cheap process for pure terephthalic acid suitable for polyester fibres.

IPC: C07C51/41
Filed: 1970-03-11
Abstract: Prepn. of solid quaternary ammonium salts of amines and 2,4-dichlorophenoxyacetic acid is effected by dissolving the acid in a solvent substantially immiscible with water but miscible with the amine, which does not react with the amine or the acid and in which the quaternary salt is insoluble and reacting the solution with the amine and collecting the quaternary salt by filtration. The quaternary salts are water-soluble, non-corrosive herbicides which are stored and transported more economically than the usual aqs. solutions. The process is suitable for batch or continuous operation.

Patent DE-2138531-A1 (DE)
Title: Foundry sand cooler - with vertical shaft
Inventor: TUTZSCHKY RUDOLF
IPC: B22C5/08
Filed: 1971-08-02
Abstract: The cooler comprises a vertical or near vertical rectangular cross section shaft through which the sand is gravity passed with cooling inlet and outlet opening on two opposite sides through which a horizontal cooling air stream is passed. In the prefd. working the sand is still or nearly so when the coolant air is passed, so that it does not pick up excessive amounts of dust. The fact that little dust is picked up by the coolant air means that no elaborate dust extraction provisions have to be made for its cleaning prior to its being passed to atmosphere.

Patent DE-2157037-A1 (DE)
Title: Fuel element cladding defect location - by increased fission product activity
Inventor: GOLLY WERNER DIPL ING
IPC: G21C17/04
Filed: 1971-11-17
Abstract: Detection of fuel elements cladding detects by measurement of the increased fission product activity induced either by a reduction in coolant pressure or by power raising to increase fuel temp. The fission product activity response curves are significantly different for cladding defects in the region of the fuel compared with those in the fuel element plenum chamber. Examination of the curves enables a positive evaluation of the defect location to be made and aids decisions on fuel changes with consequent advantage to reactor availability and fuel economics.

Title: Programming data carriers e.g. plastic foils - metallic layer is applied and vaporised for data input
Inventor: BUEHL HERMANN DIPL-ING
IPC: G06K1/12
Filed: 1973-10-19
Abstract: The process and arrangement apply to the programming of data carriers, such as foil material of e.g. plastic to which a thin layer of metal e.g. aluminium, copper etc. is applied. The blank carrier is then moved along a path by a driving cog past a contact roller connected to a high tension source. This is connected through individual switches to a number of electrodes which are controlled by a logic switch so that heat is applied through the electrodes to particular points on the carrier. The heat is sufficient to remove the metal layer at these points, so that subsequently they can be read, optically or electrically by a reader.
