Patent DE-2143262-A1 (DE)
Title: Blow moulding double walled vessel - from injection moulded parison
Inventor: KNIPP KARL
IPC: B29C49/06
Filed: 1971-08-28
Abstract: Moulding a double-walled hollow thermoplastics object uses enjection moulding to produce a parison, and then blowing to form the final object from this parison. The parison is made in a multi-part mould comprising two coaxial cores entering from opposite directions one of which contains the sprue for injection moulding; after the mould components have moved laterally sideways and one core has been withdrawn, the blow moulding assembly is brought into contact around the parison, thus closing the previously open end left by the withdrawn core. Blow moulding is then completed in this posn.

Title: Recognition and printing process for words and letters - compressions and rarefactions converted to positive and negative potentials
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/00
Filed: 1974-04-09
Abstract: When pronouncing a word or letter the resulting positive and negative tensions to the nought line are decided independently from each other. The bias of the circuit is a signal for the previously recorded letter or word and can be printed through the signal. The same sounds spoken loud or soft have a large or small amplitude but the bias of the circuit is approximately the same, so sound integration is not necessary. The equivalent a.c. is made visible on an oscillograph and the letters are printed from a store. The appropriate letter is released and printed on the basis of comparison with the given example.
