Patent DE-3114154-A1 (DE)
Title: Planetary gear with elastically deformable planets and roller chain mechanism
Inventor: STEUER WILLI DIPL ING
IPC: F16H9/26
Filed: 1981-04-08
Abstract: The invention relates to a planetary gear with one or more elastically deformable planets distributed on the circumference of a gear stage, which elastically deformable planets deviate from the circular shape and are adapted in oval to sausage-shaped form to the annular cylindrical cavity between sun gear and peripheral gear (zenith gear) and transmit movement and force, as can be seen from the drawing in Figure 1. In this way an improved load distribution, greater force transmission and smaller loading per tooth is achieved on the circumference of the driving gear and of the driven gear. Possible elastically deformable planets are closed, radially stabilised V-belts or closed, radially stabilised elastic roller chains. The roller chains are designed in such a way that they can transmit force by pushing and pulling. On account of the deformability of the planets, the latter can be introduced into the circumferential space from outside, through an opening in the circumferential gear, which opening can be closed with a cap, as a result of which an easy assembly and straightforward replacement in the case of repair work are made possible. <IMAGE>

A mortar (19) is arranged so that it can be lowered (can be lifted) from the driving piston "T" (firing position "F") into the firing position "F" (driving position "T") along a straight-line direction of an arrow (60, 58), by means of a device (46). The barrel of the mortar (19) is divided, an upper part (26) being connected to a housing (24) (which can be elevated via (50)), while a lower part (28) (with a spherical joint (30) at the rear end (29)) can be pivoted by means of a tilting device (52) so that it can be aligned with the opening (16) (arrow 66) for loading or can be aligned with the barrel part (26) (arrow 68) for firing, and in this way carries out the function of a tilting seal. During pivoting for loading, a firing bolt spring is cocked, which can be released for firing after pivoting in the direction of the arrow (68). Loading is carried out from the interior (14) through the opening (16) in the barrel part (28) aligned therewith. <IMAGE>

Patent DE-3128429-A1 (DE)
Title: Device for separating components, which under normal conditions are gaseous, from a gas mixture
Inventor: MUELLER MARTIN DIPL ING
IPC: B01D53/14
Filed: 1981-07-18
Abstract: In a separating device for separating a component, which under normal conditions is gaseous, from a gas mixture by spraying with a liquefied inert gas, the gas mixture is, for its intensive precooling, guided through a gap between an outer stator and the rotor outside, a great heat transmission to the rotor plate, and thus an intensive precooling, taking place as a result of the high relative speed between gas and rotor. The gas flowing off flows through the gap between rotor inside and an inner stator, a good heat transmission to the rotor plate, and a further cooling, also taking place here.

Title: Process and apparatus for the preparation of metabolic products using microorganisms
Inventor: BRAUER HEINZ PROF DR ING
IPC: C02F3/12
Filed: 1981-12-23
Abstract: The invention relates to a process for the preparation of metabolic products using microorganisms in aqueous medium, which is particularly suitable for biological purification of waste water, to a bioreactor (10, 14) for carrying out this process, and to a multistage biological waste-water purification plant with at least one of this type of bioreactor (10, 14). The microorganisms are exposed in the bioreactor (10, 14) to mechanical stress, which does not lead to their dispersion but significantly increases their metabolic rate. Several embodiments of bioreactors (10, 14) are indicated, in which the microorganisms are activated by supplying energy via the aqueous medium. The multistage waste-water purification plant has at least one stage with a bioreactor (10, 14) suitable for activating the microorganisms. This makes it possible greatly to reduce the residence time of the substances to be converted in the bioreactor (10, 14) and in the waste-water purification plant. <IMAGE>
Patent DE-3202955-A1 (DE)
Title: Process for producing ready-mixed masonry mortar for lime-sandstone masonry
Inventor: EDELMANN ALBERT PROF DIPL ING
IPC: C04B18/12
Filed: 1982-01-29
Abstract: The invention relates to a process for producing ready-mixed masonry mortar for lime-sandstone masonry. Lime-sandstone masonry is very avid for water and very intensively absorbs the incorporated ready-mixed masonry mortar's own water which it needs for its own long-term setting. In the known ready-mixed masonry mortars, this water removal effected by the lime-sandstones leads to a deterioration in the quality of the mortar, i.e. to a reduction of its compression strength. The invention is based on the object of diminishing this disadvantage and at the same time proposing aggregates, which arise as waste materials at no cost and up to now have caused transport costs on the way to the landfill and, at the latter, an evolution of dust which pollutes the environment. This is achieved by adding powdered rock of greywacke and/or basaltoid rocks such as, for example, basalt, tephrite, andesite, dacite, latite or basanite as an aggregate or filler, which are removed as waste products from the air classifiers (cyclones, extraction devices, filters and the like) used in the comminution of natural rocks to give ballast.

Patent DE-3212697-A1 (DE)
Title: Pressure monitor for washing or rinsing machines
Inventor: BAADER HELMUT DIPL PHYS DR
IPC: D06F39/08
Filed: 1982-04-05
Abstract: In a capsule (10), a movable wall (20) separates a switch chamber (24) from a measuring chamber (26) which is connected via a conduit piece (28) to a space to be monitored. The conduit piece (28) contains a screw plug (34) which bears only with its thread crowns (36) against the smooth inner wall (30) of the conduit piece (28) and thus forms a throttle channel (38). The throttle channel (38) has a highly vibration-damping effect because of its great length in relation to the length of the conduit piece (28) and thus keeps random air-pressure fluctuations away from the measuring chamber (26). <IMAGE>
Patent DE-3215404-A1 (DE)
Title: Process and apparatus for the biological purification of waste water
Inventor: REIMANN HANS DR
IPC: C02F3/06
Filed: 1982-04-24
Abstract: A process and an apparatus are described for the biological purification of phosphate-containing waste water, in which the waste water is aerobically treated in a reaction zone in the presence of an activated sludge at least in part fixed to a support material and then an essentially phosphate-free waste water stream is withdrawn. In order to achieve, by simple and economic means, high purification values, especially with regard to the phosphate removal, it is proposed to treat the waste water in at least two reaction zones and to carry out the treatment in a time cycle under aerobic, anaerobic and, possibly, anoxic conditions. During this, the biomass fixed to the support material remains in the particular reaction zone and is subjected, in a specific time cycle adapted to the particular conditions of the waste water, to aerobic and anaerobic and, if nitrification or denitrification is carried out, to anoxic conditions.
