Patent DE-3820611-A1 (DE)
Title: Device for manufacturing components made of ceramic or refractory material with at least one incorporated slot-shaped through-duct
Inventor: BENDER GUENTER
IPC: B28B7/18
Filed: 1988-06-16
Abstract: The invention relates to a device for manufacturing components made of ceramic or refractory material with at least one incorporated slot-shaped through-duct, in particular for manufacturing a gas circulating brick for metallurgical vessels. To produce the through-duct, use is made of a mould core (3) which corresponds to the shape of the through-duct to be produced. The mould core is immersed in a molten lubricant which, after the mould core (3) is drawn out, adheres thereto by solidifying. The mould core coated with the solidified lubricant is inserted into a mould (1) in such a manner that at least one core end projects from the component to be manufactured subsequently. The raw material for the component is then introduced into the mould and, after the solidification of the component, heat is supplied to the mould core. After the lubricant layer has melted, the mould core (3) is drawn out of the component. In order to facilitate or render superfluous the clamping in of the mould core, the mould core (3) consists of at least one sheet-metal strip (4) with an arc-shaped profile which has sufficient rigidity so that the mould core becomes self-supporting. <IMAGE>

Patent DE-3843088-A1 (DE)
Inventor: CORKE GORDON L
IPC: F16J15/48
Filed: 1988-12-21
Abstract: A seal mounted in a connector 34 housing which is adapted to be connected to a conduit 17 and has a generally outwardly projecting seal receiving recess formed therein. The seal is sized on three sides to make a close fit in the seal receiving recess and comprises a central core 12 formed from an elastomeric material; the remaining surface of the seal makes a sealing contact with a surface on a duct 17. The three sides may be covered by two plys of silicone impregnated fiberglass, the fiberglass fibers forming passageways which lead to the outer periphery of the seal. In this way gas pressure in the conduit is transmitted to the outer periphery of the seal inside the recess where it exerts an inwardly directed force on the seal to cause the work engaging surface of the seal to make a sealing engagement with a surface on the duct. <IMAGE>

Title: Element for identifying chemical-fibre, flat-fabric lifting bands and/or slings provided for moving loads
Inventor: DOLEZYCH UDO
IPC: B66C1/18
Filed: 1989-02-14
Abstract: In elements for lifting or moving loads, the demand has essentially been for markings which indicate lifting capacity. To protect manufacturers as well as consumers or users in accordance with product-liability provisions as well as authorised use and maintenance, it is necessary to supplement the identification of the elements by adding further details such as, for example, type of material, refinement state, suitability for special conditions of use. For this, the invention proposes a separate identification bearer (3) which, to identify the specific features of the lifting band (1) or sling to be identified, has symbols (5) in at least two separate symbol zones (4a, 4b) and is connected to the band (1) in such a way that in each case the one area (6a) of the identification bearer (3) with the one symbol zone (4a) is arranged on the one flat side (7a) of the band (1), and the other area (6b) of the identification bearer (3) with the other symbol zone (4b) is arranged on the other, antipodal flat side (7b) of the band (1). <IMAGE>
