Patent DE-2253385-A1 (DE)
Title: Synthesis gas - from oil using temp modifying gas to displace combustion from burner tip
Inventor: MARION CHARLES PARKER
IPC: C01B3/36
Filed: 1972-10-31
Abstract: Synthesis gas is mfrd. by the partial oxidn. of a normally liquid hydrocarbon oil at 1800-3500 degrees F with free O2 in the presence of H2O or CO2 as a temp. moderating gas (TM gas). The free O2-contg. gas is introduced into the reaction zone through the central nozzle of a triple orifice burner, a stream of the oil carried as a fog in the TM gas is introduced through an outer coaxial nozzle whilst a stream of the TM gas issues through an intermediate, annular coaxial nozzle as a sheath of uniform density and volocity. That sheath separates the free O2 from the oil for a substantial distance downstream of the nozzle and so prevents the O2 from reacting with the oil or recirculating synthesis gas close enough to the nozzle tips to damage them.

Title: Impurities removed from extruder material - by fitting curved scrapers on perforated discs at the nozzle end
Inventor: TENNER HELMUT
IPC: B29C48/693
Filed: 1973-05-16
Abstract: Scrapers of involute curved shape lie between the end of the screw and perforated discs so that impurities are moved towards the centre by the scrapers which rotate with the screw. There they pass through a hole in the discs and into a radial bypass channel fitted in the nozzle housing. This bypass has its own heater and a control to maintain the internal pressure at a higher level than at the main nozzle area. The device thus operates continuously and selection of hole size in the perforated discs determines the grade of filtration achieved.
Patent DE-2340182-A1 (DE)
Title: Data storage using a magneto-optic memory layer - made of matl. with a magnetic phase transition in working temp. range
Inventor: UNGER WILLIBALD DIPL-PHYS DR
IPC: G11C13/06
Filed: 1973-08-08
Abstract: The layer is made of a matl. with a coercive force (Hc) which drops sharply when a temp. rise occurs in the prescribed working range. The laser beam only heats a spot on the layer to a temp. slightly above the working temp., i.e. to the read-in temp. which is below the Curie temp. At the read-in temp. a low Hc occurs (X) and a magnetic field is simultaneously applied, the field-strength of which is larger than (X) but lower than the Hc of the unheated part of the layer. The pref. matls. for the layer are FeRh or FeRhXy where X is Pd, Ru, Ir; or Cr2S3, Cr5S6, Mn1-xLixSe, Mn1-xLixTe or Mn2-3CrzSb. The advantages are that as the temp. rises for read-in is 30 degrees C., only a low-intensity laser beam is required, and the applied magnetic field is always Hc at room temp.

Title: Metallised plastic moundings prepd in two stages - have appearance of all metal object
Inventor: VOSS FERDINAND
IPC: B29C37/00
Filed: 1973-09-18
Abstract: Plastic mouldings metallised on the surface are prepd. in two stages (1) deposition of a thin layer of metal-powder filled thermoplastic on the mould surface, and (11) before layer (1) is hardened, filling the mould with thermoplastic or thermosetting material. Stage (1) uses polystyrene, ABS or SAN dissolved in its monomers, or PVC dissolved in methylene chloride, and mixed intimately with polymerisation catalysts and powdered Cu, Sn, Al, bronze or brass. Stage (11) uses a thermoplastic as a viscous mass or as sheet, or an unsaturated thermosetting resin, sprayed or pressed onto the first layer. Such metallised objects reflect mould surfaces accurately, look like real metal objects andwithstand subsequent operations e.g. polishing.

Title: Treatment of hyperlipaemia with vitamin B12 - administered orally or locally
Inventor: KOEHLER VALENTIN DR MED
Filed: 1973-11-16
Abstract: A medicament for the curative or prophylactic treatment of hyperlipaemia, for oral or local (on the skin or mucous membrane) administration, comprises vitamin B12 in a suitable vehicle. Oral or local administration of vitamin B12 reduces or normalises serum lipid levels (cholesterol, beta-lipoproteins, triglycerides) in a relatively short time, e.g. 2 weeks; parenteral administration does not have this effect. The daily dose is pref. 750-1000 mug vitamin B12. The medicaments can be formulated as solns., syrups, suspensions, tablets, capsules, creams, ointments, etc. The effect of the vitamin B12 can be potentiated by including folic acid in the medicament in a dose below that which raises the cholesterol level; this further reduces triglyceride and lipoprotein levels.
