Patent DE-2207638-A1 (DE)
Title: Addn of colouring matter to plastic granulates - using a dry process
Inventor: HITZLER ALFRED
IPC: B29B7/88
Filed: 1972-02-18
Abstract: The kinetic energy of pneumatically fed granulate is used to govern the addn. of dry colouring matter. A jet of granulate is directed upwards to a loose sieve which is the base of a container holding the colour powder. Energy of the jet agitates the sieve, so that colouring matter falls through and mixes with the granulate sufficiently homogeneously for immediate use in many applications. If the granulate is alternatively a fine powder an upper plate over the sieve prevents it from entering the colouring mass.

Title: Welding steel or aluminium plates - using metal-inert gas combined with hot wire process for heavy root passes
Inventor: KAEMPNY HANS-HUBERT DIPL ING
IPC: B23K9/173
Filed: 1973-12-20
Abstract: The inert gas welding process is esp. for joining thick plates using seam-edge prepn. and a root welding pass followed by a filling pass or passes, the novelty being that the root pass is made by metal inert gas welding (MIG) using high current and the filling pass(es) made by the hot wire process. The hot wire pref. follows the MIG electrode wire, using the same molten bath, the MIG wire using a current density above 250 A/mm2 of the wire cross-section and a wire dia. of 0.8-2.4mm. Alternatively, an MIG wire of 1.6-4.0mm may be used with a current of 400-900 amps. The MIG- or the hot wire electrode may be cored. The term hot wire means the use of a wire carrying A;C. or D.C. where the wire is permanently immersed in the molten metal and melted primarily by resistance heating. Used for container and ship welding of steel plate 5-50mm thick, also Al plate. Avoids submerged arc-welding, tack welding, the use of a pad under the seam, and turning the plates over; the process can be applied by machine.

Title: Measurement of volume flow in air-channel - is simply achieved using vane mounted across airflow
Inventor: SEPPAENEN OLLI ANTERO DIPL ING
IPC: G01F1/28
Filed: 1974-07-15
