Patent DE-2524596-A1 (DE)
Title: Reaction vessel for melt synthesis of cpds - has reservoir closure for volatiles with mechanical-liq. seal
Inventor: MENASHI WILSON POUR
IPC: B01J19/24
Filed: 1975-06-03
Abstract: Reaction vessel for the melt synthesis of an inorganic cpd. from elemental reactants, one of which is non-volatile and another of which is volatile at elevated temp., comprises an enclosure defining a reaction chamber contg. a molten mass of the non-volatile reactant and the inorganic cpd. and a closure for an access opening in the enclosure defining a reservoir for the volatile reactant. A channel around the access opening contains a liq. sealant which forms with the closure a liq. mechanical seal which prevents liq. sealant entering the reaction chamber but allows the diffusion of high press. gases. The closure has in its base a removable plug with a channel for the flow of the volatile reactant as a gas into the reaction chamber. The vessel is used for the mfr. of polycrystalline GaP ingots. Since the liq-mechanical seal allows diffusion of high press. gases the press. within the outside the reaction chamber can be maintained the same. Thus a thick walled vessel can be eliminated and large batches can be handled.

Patent DE-2526033-A1 (DE)
Title: Plastics printing block having embossed picture points on one surface - using thermoplastics foil provided with hot embossed picture elements
Inventor: RITZERFELD GERHARD
IPC: B41N1/12
Filed: 1975-06-09
Abstract: The parent patent described mfr. of a printing block provided with raised picture points applied by embossing, using a thermoplastics foil provided with picture point embossings by the action of heat. In this addn., the thermoplastic foil is one that has a printing (obverse) side with the embossed picture points, and a reverse side that is unembossed and flat. In the parent patent, the foil has even thickness even after the embossing, the reverse side having depressions associated with the raised embossings on the obverse (printing) side. As a result, contact of the reverse side with an under-lying original copy is imperfect and heat transfer from heated image zones of the original to the printing block foil impeded. This renders excessive heating of the image zones necessary and impairs accuracy of image reproduction. The present improvement eliminates these shortcomings. The thermoplastics foil may be of PVC, thickness (in non-embossed state) 0.06-1 mm.
Patent DE-2526168-A1 (DE)
Title: Stoneware prodn. from clay flour filled with hardened granules - which are prepd. from the same clay and adhesive, to eliminate shrinkage difference
IPC: C04B33/16
Filed: 1975-06-12
Abstract: Prodn. of stoneware (pipes or other shapes) is improved by adding to the clay flour granules produced from the same clay sprayed with an adhesives soln. and dried. Stoneware such as pipes, plates, parts of chemical appts., electric insulators, or other refractory articles can be produced by this method. The shrinkage of the granules during the firing is the same as that of the matrix so that cracking is eliminated. The spherical form of the filler eliminates stresses and voids which arise when clay filled with e.g. jagged particles of crushed chamotte is moulded and fired. The compressive strength of the product, the density, the abrasion resistance, and the resistance against corrosion and attack by chemicals are greatly increased (the compressive strength is doubled). The products are resistant to infiltration and dissolution by liquid slags.

IPC: B01D53/34
Filed: 1976-09-29
Abstract: Methods of, and appts. for purifying by decomposition at 800-1000 degrees C., waste gases contg. organic or mineral substances, in which the flow of gas varies between wide limits is claimed. The concn. of O2 and of combustible substances varies so that the explosive limit is sometimes exceeded; supplementary combustible is added to maintain the decomposition temp. According to the invention, air or waste gas which contains no combustible substances, is added to the waste gases, the flow regime is made laminar and the gas mixt. is sent to the combustion chamber, with no boundary layer on the wall of the inlet duct. The quantity or combustible-free waste gas is added in a constant proportion which maintains the rate at a value defined on a curve determined experimentally, between 3 and 20% of the max. flow rate of the waste gases. The invention ensures direct combustion of flammable waste gases in a burner which prevents propagation of a backward flame and reduced explosion risk, to a greater extent than is possible with existing methods, and without incurring the high capital and running costs associated with existing methods.
