Title: Shoe manufacturing apparatus for full automatic production - comprises moulding last and sole mould for finishing preshaped upper
IPC: B29D35/10
Filed: 1973-12-04
Abstract: The moulding last is associated with one or more holding clamps for the shoe upper so that after the upper has been shaped it is held down by these clamps on the moulding last so that the sole can be attached. This means that the upper cannot slide about on the last but is correctly aligned so that the edge of the upper can be kept relatively narrow, thereby saving material. The clamps are designed to move down vertically onto the front part of the last and horizontally against the side parts of same whilst the upper is held down by its edge which protrudes beyond the sole of the last. This dispenses with the need for attaching a welt and the manual, time-consuming processes associated therewith so that the shoe production is rationalized.

Title: Nitrogen-fixing blue algae cultivation - in fesh water or its mixts with sea water opt with addition of trace elements
Inventor: POHL PETER DR
IPC: A01G33/00
Filed: 1973-12-17
Abstract: Nitrogen-fixing blue algae, such as Anabaena or Nostoc are cultivated in fresh water or its mixts with sea water, opt. with addn of trace elements, esp. salts of Fe, Mn and Mo. The blue algae can be used for prepn of human or animal food. Since the blue algae assimilate nitrogen from air, there is no need to introduce into the cultivation medium nitrates or ammonium salts (as in the case of green algae cultivation); only cpds of other nutrient elements, such as P,S,Na,K,Ca,Mg,etc. and trace elements have to be supplied, and only in reduced quantities if sea water is used, as it contains considerable amts of nutritives. Thus, the costs are considerably reduced, esp if blue algae cultivation is carried out near sea-coast.

Title: Transmission system causing nonlinear distortion - has distortion correcting element with characteristic similar to that of the system
Inventor: KIESEL KURT DIPL ING
IPC: H04B3/06
Filed: 1973-12-24
Abstract: The correcting element is in series with the transmission system. In order to achieve a complementary transmission characteristic, its output signal is added in opposite phase to a signal part branched off before the correcting element, so that original amplitude relations are restored. The correcting element is connected before the transmission system to be corrected. The addition with opposite phases of the correcting element output signal, at first cophasally predistorted, to the non-distorted original signal is done after the latter has passed through a suitable delay line. Restoration of the original signal amplitude relations is done without amplification of distortion components in the correcting element output signal.
