Title: Process and apparatus for the biological purification of waste water
Inventor: FUCHS UWE ING GRAD
IPC: C02F3/12
Filed: 1983-07-07
Granted: 1987-03-05
Abstract: In the treatment of wastewater, the mixture of wastewater and the sludge is transported through a treatment zone, and then through a filter zone containing a bed of support particles, e.g., particles of polyurethane foam, to deposit the biomass onto the support particles. The loaded support particles are subsequently regenerated within the filter zone by means of a regenerating means in the same area as the filter zone, e.g., by strong aeration or by being compressed between press-rolls, whereby the system requires neither additional land for regeneration of the support particles nor a secondary settling tank.

Title: Method of and tool for bending the marginal sections of sheet metal
Inventor: JONSSON FINN LENNART
IPC: B21D5/02
Filed: 1983-11-08
Granted: 1987-06-11
Abstract: For bending the edge of a thick sheet of metal a tool comprising a yoke with a long and a short leg with plate-engaging bars in the opening between the legs is used. The tool is placed on a sheet so as to straddle the edge to be bent with one bar on each side of the sheet. An extensible member, for example a hydraulic cylinder, bears against the sheet to tilt the yoke so that the bars are pressed against the sheet to bend it. The tool may be provided with transport wheels and drive equipment for automatically moving the tool on the sheet.

Title: Leakage detector for the barrage of a nuclear pool
Inventor: SIMON ANDRE
IPC: G21C19/07
Filed: 1983-03-01
Granted: 1987-12-10
Abstract: System for partition doors used in underwater storage facilities for nuclear reactor fuel rods comprises a double seal extending around the periphery of the door so that a dead space is formed between the two seals.  This space is connected by a pipe to a remote level-detecting system comprising two level detectors mounted at different elevations. A branch pipe connects the dead space also to a pump.  In the event of leakage into the dead space, the fluid passes to the first level detector which triggers an alarm.  If no corrective action is taken and the level reaches the second detector, the pump is automatically started to clear fluid from the dead space.  The time taken between triggering the two alarms gives a measure of the rate of leakage.  The seal assembly comprises two continuous, resilient, seal tubes extending around the door periphery.

Patent DE-3484777-D1 (DE)
Inventor: HANSEN ECKARD
IPC: A47C1/032
Filed: 1984-10-29
Granted: 1991-08-08
Abstract: The chair has a seat plate (2), which is mounted rotatably on the seat support (1) at the attachment point (3). The backrest support (4) is connected in an articulated manner by an arm (5), extending below the seat plate (2), on the one hand to the seat plate (2) and, on the other hand, by means of a double-jointed lever (10') also to the seat support (1). A gas spring (7), which can be arrested in any desired positions, acts on the backrest support (4) and has the tendency to bring it into the position drawn in continuous lines. When the chair is moved out of the latter position into the position drawn in dot/dashed lines, the seat plate (2) swivels only approximately half as far as the backrest support (4). In this case, it is essential that, despite the synchronous movement of the seat plate (2) and the backrest support (4), no effects arise which cause the shirt to be pulled out. The path of the gas spring increases progressively as a function of the rearward movement of the backrest, with the result that the force acting on the backrest due to the gas spring (7) is likewise greater with the increased inclination of the backrest. <IMAGE>

Abstract: 57 The invention relates to a new process for producing titanium IV and zirconium IV pyrophosphates, certain of which are new compounds, and their uses. The pyrophosphates are prepared by reacting a metal tetraester with phosphorus pentachloride, with or without the addition of an hydroxyl compound, such as an alcohol or a phenol.

Abstract: In filters for cleaning the exhaust gases from diesel engines having openpored foam ceramic bodies, the deposited soot particles are burned up at temperatures of between 550 DEG  and 700 DEG  C. at periodic intervals. In order to lower the inflammation temperature of the soot in the regeneration phase of the filter, the ceramic bodies are catalytically coated. The region of the openpored foam ceramic body first subjected to the flow of the exhaust gases of the diesel engines has at least partly a denser pore structure than the remaining foam body so that the inflammation temperature can be lowered since temperature peaks occur in these regions on account of increased soot deposits, which temperature peaks lead to inflammation of the soot located there and consequently burn up all the soot deposited in the filter.

Abstract: The web (W) is reeled by supporting the roll (30) from its outer circumference by means of at least two supporting units (10,20), of which the first one, in the direction of arrival of the web (W), is a carrier roll (10) provided with a mechanical rotating drive (10a), over which the web (W) is passed to reeling. The carrier roll (10) forms a reeling nip (10/30) supporting the roll (30) from below. Above the roll (30), a press roll (21) is used, by means of which the roll (30) is kept stably in its reeling position. The roll (30) is grown around a core (31) under a nip support between the carrier roll (30), a belt roll (12) and the upper press roll (21). When the roll (30) grows and becomes larger, the reeling goes on further under the nip support between the carrier roll (10) and the upper press member (21) and, in addition to this supporting, on a belt supporting zone placed as a direct extension of the nip support zone of the belt roll (12). The final stages of the reeling are carried out up to full roll (30) by extending the belt support zone and, at the same time, by adjusting the tensioning (T) of the support belt or belts (15) so that the linear loads in the various supporting nips of the roll (30) remain within suitable limit values in view of the progress of reeling and of quality of roll (30).
