Patent DE-3415722-A1 (DE)
Inventor: FISCHER HERBERT
IPC: C01B17/04
Filed: 1984-04-27
Abstract: The feed gas is partially burnt with oxygen-containing gas in a thermal Claus process plant, in which temperatures in the range of 850 DEG  to 1350 DEG  C. is maintained. Product gas which has been produced is passed through a catalytic Claus process plant (Claus catalysis plant), from which sulfur is withdrawn. The exhaust gas from the Claus catalysis plant is supplied to a desulfurizing plant. The sulfur compounds in the exhaust gas of the desulfurizing plant are converted to SO2 in a thermal aftertreating unit. When the rate of the H2S-containing feed gas is below a limit, which is between 20 to 35% of the total rate of feed gas permissible for the thermal Claus process plant, then recycled exhaust gas from the desulfurizing plant (recycle gas) is admixed to the feed gas at such a rate that the rate of the mixed feed and recycle gases exceeds that limit. The recycle gas is suitably heated to 200 DEG  to 400 DEG  C. before it is mixed with the feed gas.

Title: Method and apparatus for producing foundations by embedding precast members, in particular pillars, in the end base
Inventor: ESTERS KLAUS DIPL ING
IPC: E02D5/44
Filed: 1984-05-05
Abstract: A method and apparatus for producing foundations by embedding precast members 4 in the end base 1 are proposed. The end base 1 is produced on or in load-bearing subsoil by use of the vibratory method or the soilcrete method. In the process, the borehole 2 lying above the end base 1 is supported and kept open by a supporting liquid, in particular a cement suspension 3. Instead of the method practised hitherto on the construction site by inserting a reinforcing cage and filling this cage with ready-mixed concrete, the precast member used in the novel method is produced in batches remote from the construction site. By appropriate design and reinforcement of the precast member 4, the absorption of the vertical and horizontal forces in the foundation can be calculated in advance, controlled and loaded and is thus also to the greatest extent independent of critical soil boundary zones 5, such as, for example, peat and bog layers. The precast member is transported from the plant to the construction site and is let there into the borehole 2 (filled with cement suspension 3) until it strikes the end base 1. The cement suspension 3 displaced by the precast member 4 penetrates into the soil boundary zone 5 and compacts the soil layers. The precast member 4 is frictionally connected to the end base 1. Use is made for this purpose both of mechanical aids such as anchors 8 as well as of the subsequent grouting of the contact zone between precast member 4 and the end base 1 by means of ...

Filed: 1984-05-17
Abstract: Process for the subsequent treatment of domestic refuse. The domestic refuse is compressed. The compressed domestic refuse is converted into a gaseous component and a solid residue. At least the gaseous component is used for the production of heat. The ram extrusion process is used for compressing the domestic refuse. During this, a domestic refuse rod is extruded from a ram extrusion cylinder and forced into a distillation cylinder which has at least one heating zone. In the heating zone, the domestic refuse rod is subjected to dry distillation. During this, the gaseous component is formed and the domestic refuse rod is coked to form a coke rod. The gaseous component, together with the coke rod, is transported to the end of the distillation cylinder. The gaseous component is taken off there.
Patent DE-3430713-A1 (DE)
Title: Slide fasteners: single-sided or two-sided coating of slide fastener stringer tapes with a synthetic adhesive, which melts under heat or steam, or a contact adhesive
Inventor: WECHSLER MANFRED
IPC: A41D27/24
Filed: 1984-08-21
Abstract: When including slide fasteners in garments, e.g. skirts, dresses, jackets, etc. (even in tents or similar articles), considerable difficulties arise in free-hand sewing-in, even if the slide fastener has previously been pinned. Oblique tension, stretching or even undulations occur on the upper material. Additionally, the sewing-in is very time-consuming. When using a coated slide fastener, the latter can be glued in using an electric or steam iron, which can be carried out quickly and without problems (even by non-experts). The subsequent final sewing of the slide fastener using a sewing machine requires less time and results, above all, in a smooth appearance of the surface of the processed articles (skirts, blouses, dresses, etc.). The drawing shows a slide fastener coated with polyamide as well as a glued-in slide fastener in a jacket. <IMAGE>

Title: Actuating device for pull-push cables or the like
Inventor: MAIER KONRAD
IPC: G05G7/02
Filed: 1984-09-08
Abstract: A description is given of an actuating device for push-pull cables or the like, in which a slide is displaced with the attached push-pull cable by means of a double-armed actuating lever. On its working side, the double-armed actuating lever has at least two working arms, each of which bears a pin. Each of the pins interacts with an upwardly open slot in the slide in such a way that, when the actuating lever is rotated, one of the pins emerges from its slot when the other is just entering its associated slot. In comparison with prior-art actuating devices operating with pin/slot connections, this provides an enlargement of the displacement travel of the slide by the extent of the spacing of the slots.
Patent DE-3433450-A1 (DE)
Title: Laminate stack for electrical machines having closed slots
Inventor: BORRECK HERBERT
IPC: H02K1/16
Filed: 1984-09-12
Abstract: Closed slots in the region of a winding strand result in a closed outlet surface being available to the lines of force which occur. In consequence, the flux of the lines of force over the path of the winding strand is largely homogenous. On the other hand, the closed surface over the slots of the winding strand conducts the magnetic flux which occurs to all the slots, even when the flux is inserted on one side, as is generally the case with rotating machines. The induced voltage response in the winding strand is improved as a result of the more uniform magnetic flux.

Title: Process and plant for heat-treating mineral raw meal, in particular carbonate-containing raw meal
Inventor: BAUER CLAUS
IPC: C04B7/43
Filed: 1984-09-14
Abstract: In a process for heat-treating carbonate-containing raw meal, which is preheated in suspension with hot carrier gas, precalcined while passing through a reaction section of a calcining zone, burnt in a burning zone and the burnt material is cooled in a cooling zone, solid fuel and fuel gas being added to the meal for covering the heat requirement of the calcining reaction, difficulties arise due to insufficient calcination when fuels are used which are difficult to ignite or burn out sluggishly. As a remedy, it is suggested that the fuel used is a fuel which is difficult to ignite, in particular has high ignition temperatures and/or burns off sluggishly, and that, in the intake region of the reaction section, the fuel but only a part quantity of the preheated raw meal are charged at a first raw meal-charging point and that, at at least one second raw meal-charging point located downstream of the first raw meal-charging point, at least one further part quantity of raw meal is charged to the reaction section. A plant for carrying out the process has a raw meal-dividing device (16' 17', 18', 21) connected by means of proportioning lines (16'', 17'', 18'', 19'') to raw meal-charging points (16, 17, 18) located on the calciner (7) at intervals in the direction of flow. <IMAGE>
