Title: Grab for wood
Inventor: KINSHOFER ALFRED
IPC: B66C3/04
Filed: 1987-12-28
Abstract: A grab is used preferably for grasping stacked logs or logs to be stacked. It has two U-frame-shaped grab arms which are mounted on a central supporting frame so as to be pivotable towards and away from each other in a tongue-like manner about mutually parallel axes, which form, together with upwardly projecting actuating levers to which are linked pressure-medium piston-cylinder units and/or synchronising linkages, two-armed levers and which comprise two sickel-shaped curved lateral legs the free outer ends of which are connected to each other by plates forming grab edges. The legs of a grab arm are bent off inwardly by two mutually opposing bends in such a manner that the outer ends of these legs reach through between the legs of the other grab arm in the closing region. The supporting frame comprises a yoke-like transverse beam having mutually parallel beam-like bearing plates at the ends, which bearing plates are provided, at their end regions, with bearings having mutually aligned bearing balls for mounting the grab arm. So that trunks loaded with such a grab onto a transport vehicle or the individual trunks of a woodstack can be aligned in a simple manner with one another in such a way that the cut edges of the trunks lie essentially in one plane, the unbent legs (4, 4') of the grab arms ... with the parts, located above the bends (10, 10'), of the other ...

Patent DE-3820773-A1 (DE)
Title: Process and apparatus for the compressed-air emptying of retention tanks
Inventor: STAHN ROLF
IPC: E03F5/10
Filed: 1988-06-20
Abstract: In residential-area water management, bottlenecks and emergency relief operations often occur in the area of sewage discharge, in particular in the case of combined-sewage systems. In order to avoid contamination of the receiving channels, retention tanks are arranged which, in the case of a predetermined volume, necessitate, due to lack of space, deep tank bottoms such that the tanks cannot be emptied by free-fall and water-delivering pumps have to be used. The pumping installations necessary for emptying the tanks additionally necessitate expensive undergroundengineering work. In order to reduce construction and operation costs, the invention proposes to empty the tanks by compressed air. The compressors necessary for this purpose can be set up above the ground, with the result that cost-intensive underground-engineering work is dispensed with. The air lines leading from the compressors into the tank are expediently arranged such that rising air emerging from the lines triggers a rotational flow in the tank and causes the sediment to be cleared away. In the emptying procedure, solids are automatically conveyed out of a sump, via a pressure pipeline, back into the sewage duct. The process air required for this process is used for sewage ventilation.

Title: Laying aid for leading pipelines through floors, and apparatus for securing a service-water distributor arranged beneath a concrete floor in the region of a pipeline-laying aid, and process for laying flexible pipelines
Inventor: BUERLI KURT
IPC: H02G3/12
Filed: 1989-05-22
Abstract: A pipe support (12), which exhibits an arcuate supporting portion (12a) for receiving and guiding a flexible plastic pipe, projects, with one foot (12b), into the opening of a base plate (7). The foot (12b) is mounted rotatably in the base-plate bore, with the result that the pipe support (12) can rotate to all sides and can be fixed in any position on the attachment (16) of a further foot (15), on the shuttering (5). Due to integrally formed coupling members, the base plate (7) can be connected to others in a mosaic-like manner. This ensures that the pipelines bear on the shuttering (5) at the spacings predetermined by the distributors and can thus be connected without difficulty. By means of a load-bearing rod, the distributor can be suspended on a downwardly open cap (11) which is integrally formed on the base plate (7). <IMAGE>
Patent DE-3918321-A1 (DE)
Title: Gulley with an odour-seal insert
IPC: E03F5/04
Filed: 1989-06-05
Abstract: Gulley with an odour-seal insert (18, 22, 30) which is inserted into a housing (1) such that it can be removed therefrom. Known gulleys can be connected either to horizontally running or to vertically running discharge ducts. Consequently, a relatively large amount of stock has to be kept. Known gulleys also have a relatively large overall height with a relatively low water level. In order, in the case of a gulley with a particularly high water level, to simplify the outlay for production and stock-keeping, the wall (26) which delimits the flow-deflection housing (22) on the discharge side reaches as far as the sealing flange (18) and forms an overflow edge (27) there, and the top wall (30) which covers the remaining cross-section of the sealing flange (18) is designed such that it is arched upwards, in doing so leaving free a flow-over cross-section above the overflow edge (27), and the housing (1) is designed in at least two parts, and a housing part (2, 7) exhibiting the inlet opening (3) is connected, by means of a sealed connecting flange (10, 10') which is arranged obliquely with respect to the inlet opening (3), to a housing part (8) which exhibits the gulley opening (9) which is likewise arranged obliquely with respect to the connecting flange (10, 10'), and the two housing parts (2, 7; 8) can rotate with respect to one another through 360@ by means of the connecting flange (10, 10'). The gulley is suitable for the connection of sanitary devices to a duct system. <IMAGE>

The engaging gear has a freewheel (8), whose inner race (9) with the starter pinion (10) is arranged in relation to the outer race (7) with the drive bush (5) via an additional axial springing system. During meshing and slippage, especially in the case of tooth-on-tooth contact, the inner race (9) is so unstably engaged with the starter pinion (10) that the starter pinion (10) can more easily enter the next tooth-in-recess position in the starter ring gear (28) of the internal combustion engine to be started.
Patent DE-3933326-A1 (DE)
Title: Biological removal of phosphorus and denitrification of waste water - by addn. of easily degradable organic acids during denitrification-anaerobic stage
Inventor: DOR AUGUST
IPC: C02F3/12
Filed: 1989-10-06
Abstract: In the biological elimination of P, combined with nitrification and denitrification of waste water, easily degradable organic acids are added to the denitrification/anaerobic stage, these acids being liberated during the anaerobic treatment of the raw waste water. The space loading for N breakdown is 30 vols.% for denitrification and 70% for nitrification, with 300% recirculation of the activated sludge resulting from the aerobic stage of the denitrification stage, at the same time as the P elimination. Later clarification and removal of excess sludge are carried out by the process of an activated sludge plant; excess sludge may be removed before the settling step in the later clarification, to avoid unwanted recycling of P in the later clarification. The ratio of recycled sludge is 80%. The sludge level in the pre-clarification is held constant at 0.6 m, when easily degradable organic acids are liberated in an anaerobic process (acid fermentation). The sludge is mixed by means of a plate or propeller pumps. Excessive thickening of the sludge is prevented by briefly pressing in air, e.g. through a sand trap jet, before withdrawal of the sludge. ADVANTAGE - Eutrophication of watercourse is limited, in a cheaper, simple process.
