Abstract: The disclosure relates to a granular, refractory mineral elasticizing granulate for refractory products, in particular for basic refractory products. The minerals consist of mono-phased sintered spinel mixed crystal of the ternary system MgO—Fe2O3—Al2O3 of the composition range MgO: 12 to 19.5, in particular 15 to 17 wt.-%, Remainder: Fe2O3 and Al2O3 in a quantity ratio range of Fe2O3 to Al2O3 between 80 to 20 and 40 to 60 wt.-%. Starting from an MgO content between 12 and 19.5 wt.-%, the respective mixed crystals have an Fe2O3 and Al2O3 content in a solid solution out of the limited ranges respectively indicated thereof, such that a total composition of 100% is obtained. In addition, the invention relates to a method for production of the elasticizing granulate and to the use thereof.

Abstract: Glass containers are taken to a high temperature in an annealing furnace and removed from the annealing furnace belt by grips of a gripping device. The gripping device is then moved by a handling device first vertically upwards, then horizontally above a fluidized bed and then downwards into the fluidized bed in order to coat the glass containers with a powder, it is then taken upwards out of the fluidized bed and finally moved horizontally over a conveyor belt. There, the glass containers are released from the gripping device and set down on the conveyor belt which takes the powder-coated glass containers through a second curing region in which the powder coating is cured to form a substantially duroplastic layer.

Abstract: Glass containers (3) are taken to a high temperature in an annealing furnace (7) and removed from the annealing furnace belt (5) by grips (16) of a gripping device (12). The gripping device (12) is then moved by a handling device (13) first vertically upwards, then horizontally above a fluidized bed (18) and then downwards into the fluidized bed in order to coat the glass containers (3) with a powder; it is then taken upwards out of the fluidized bed (18) and finally moved horizontally over a conveyor belt (22). There, the glass containers (3) are released from the gripping device (12) and set down on the conveyor belt (22) which takes the powder-coated glass containers (3) through a second curing region (27) in which the powder is cured to form a substantially duroplastic layer.

Abstract: Glass containers having a coating of a plastics material over at least a portion of their exterior surface are disclosed. The coatings are duroplastic powder lacquer or acrylic resin lacquer applied by a process including the steps of heating the containers, moving them into a vessel containing a coating medium, allowing the coating to adhere, transferring the containers onto a conveyor and moving the containers through a setting zone. The containers have volumes ranging between 1 liter and 0.33 liters and the ratio V, which is defined as the ratio of the glass mass of a glass container coated in accordance with the aforementioned process to the glass mass of an uncoated glass container having the same filling volume and same filled product, ranging between 0.64 to 0.87.
