Title: Plant for ladle metallurgy treatment - with several individual lances and porous bottom brick for ladle
IPC: C21C7/00
Filed: 1980-12-01
Abstract: A metallurgical treatment such as deoxidation, desulphurisation or alloying of molten steel directly in the ladle uses at least three lances which can be raised and lowered independent of each other on a lance carrier, and a chute for the admixture of alloying components. One lance has a head to measure the temperature and oxygen potential and for attachment of a sampler, the second introduces deoxidising agents (aluminium, calcium, silicon) through a steel tube with little burn-up loss, and the third is a refractory sheathed tube for the addition of desulphurising agent. A porous brick in the ladle bottom is used to introduce an inert purging gas. This is a simple method of achieving the final steel analysis in the ladle and to correct the oxygen and sulphur content of the melt, as well as its temp.

Title: Pipe support and connecting means for the connection of the pipe support and devices and process for the production thereof
Inventor: VOGEL RUDOLF DR ING
IPC: E04B1/58
Filed: 1981-03-12
Abstract: As pipe supports for projecting load-bearing structures loaded essentially by flowing media - water, air - use is made of thick-walled, large-diameter pipes which are fitted together largely by operationally loaded weld seams and are connected to one another to form load-bearing structures. As a result, the weldings are problematic and there are high flow loadings. As solution according to the invention, the pipe-support cross-sections are formed in a lamellar manner by thin-walled pipes which are pushed one into the other and have a large packing density, external diameter and overall cross-section being considerably smaller in comparison. For force transfer of the support ends, these are slit in accordance with the drawing, turned up, made solid by the introduction of means such as plastic and, while avoiding any load-bearing weld seams, are connected in a positively locking manner to other supports or structural parts, and secured, by clamping jaws which are mounted with a press fit within the frictional self-locking means. Owing to the dominance fraction of flow forces on the loading of load-bearing structures in the sea, the use of pipe supports according to the invention is particularly advantageous here in terms of safety and costs. <IMAGE>

Title: Skittle erecting system with automatic cord-length compensation
Inventor: SCHMID AUGUST
IPC: A63D5/08
Filed: 1981-04-16
Abstract: In skittle erecting systems with skittles fixed on cords, the cords stretch after a certain period of operation. In order to be able to compensate for this, the cord stock drums (6) can be twisted somewhat from time to time in the winding-up direction of rotation by a drive mechanism. This is achieved by a double toothed coupling (36, 40; 60, 66). A belt drive (22, 23, 24) connected to the chain drive drives a toothed wheel (44). This engages with a coupling toothed wheel (36), but not until, by means of an electromagnet (48), a cam disc (40) connected thereto and an untoothed sector (A) have been displaced and teeth of this coupling toothed wheel (36) have been moved into the engagement position. The shaft (38) connected to the latter in a manner proof against rotation drives, via a toothed segment, the cord stock drum (6) through a partial rotation in the winding-up direction of the cord. <IMAGE>

Title: Process for the heat treatment of carbonate suspensions
Inventor: BILDJUKEVIC VIKTOR
IPC: C13B20/04
Filed: 1981-04-27
Abstract: The technology of heat treatment of mineral suspensions with production of lime and carbon dioxide-containing gas, in particular a process for the heat treatment of carbonate suspensions, is described. The process comprises the division of the suspension (1) into a first and second fraction, the spray drying of the first suspension fraction, the calcination of the product obtained from both fractions of the suspension (1), the cooling of the lime produced from the calcination, feeding the waste gas from the calcination zone for spray drying of the first fraction of the suspension (1) and carrying off the waste gases (15) from the spray drying for carbon dioxide utilisation. Simultaneously with a spray drying of the first suspension fraction, the separate spray drying of the second suspension fraction is carried out; the product produced from the spray drying of the second suspension fraction is calcined simultaneously with the product obtained from the spray drying of the first suspension fraction. The product is calcined by the heat of a heat carrier, which heat is required for the calcination of the said product and for the drying only of the first suspension fraction, and waste gas (15) which is produced from the drying of only the first suspension fraction is carried off for the carbon dioxide utilisation. The invention can be used in sugar production for the processing of filtration deposits and also in other industrial areas.   <IMAGE>
