Title: Process and apparatus for the aerobic stabilisation of sludge
Inventor: REIMANN HANS DR RER NAT
IPC: C02F3/12
Filed: 1983-05-24
Abstract: The invention relates to a process for the aerobic stabilisation of sludge, in which the sludge, during a degradation process, is treated with air and/or oxygen as treatment gas in at least one gas treatment reactor 1, during which the sludge is circulated and kept within a mesophilic or thermophilic temperature range. To utilise the heat produced from the metabolic activity of the microorganisms, after the degradation process, the sludge is expanded in an expansion vessel 6 to subatmospheric pressure, and the vapours produced in the expansion are incorporated via a vapour line 7 directly into a sludge stream, preferably into the raw sludge incoming via a sludge feedline 2. In this case, the raw sludge is expanded by means of a vacuum pump 9 in a mixing vessel 8 connected to the vapour line 7 to the same subatmospheric pressure as the treated sludge in the expansion vessel 6. In addition, the heat transferred during the degradation process in the gas treatment reactor 1 to the exhaust gas can be utilised by connecting the exhaust gas line to a gas input device 12 arranged in the sludge feedline 2 and introducing the exhaust gas into the raw sludge (Figure 1). <IMAGE>

Title: Guiding device, used for cable ploughs, for warning strips
Inventor: SCHMIDBAUER JOSEF
IPC: H02G9/02
Filed: 1983-09-30
Abstract: The guiding device, which is used for cable ploughs, for a warning strip ensures by means of guiding elements and at least one deflection element that the warning strip is guided along in such a plane, which extends in the ploughing direction but not at right angles to the ploughing direction, within a protective chamber which is located in the ploughing direction behind the share which ploughs up the ground, as a result considerable space can be saved.

Title: Circuit arrangement for driving two-winding rotation-angle actuators
Inventor: JANETZKE HELMUT DIPL ING
IPC: H01F7/18
Filed: 1983-11-09
Abstract: A circuit arrangement is proposed for driving two-winding rotation-angle actuators, which allows both windings (1, 2) of the rotation-angle actuator to be driven alternately by driving the circuit arrangement in the form of pulses, in order thus to achieve a minimum thermal power loss from the complete circuit arrangement. When the circuit arrangement is not being driven, for example in the event of an interruption in the control line (40), the same current flows through both windings (1, 2) at the same time. In order further to reduce the thermal power loss, it is possible to insert dead times between the end of the drive period of one winding and the start of the next drive period. <IMAGE>

Title: Coloured, anodised object based on aluminium and process for the production thereof
Inventor: HANAZIMA YASUHIRO
IPC: C25D11/12
Filed: 1984-01-23
Abstract: The invention relates to a coloured, anodised object based on aluminium, with a substrate based on aluminium and disposed thereon a first and a second anodised aluminium oxide film. The inner, first film has a hardness of approximately 330 Hv or more, while the outer, second film is more porous than the first film and has a hardness of approximately 270 Hv or less. The second film is coloured with a colorant. Said design of the object is achieved in that the aluminium base substrate is anodised in an electrolyte bath at a temperature from 20 to 40 DEG C, and subsequently at a temperature of not over 10 DEG C, as a result of which the substrate thus pretreated has the two different anodic aluminium oxide films, and is then subjected to the colouring treatment.

Patent DE-3406858-A1 (DE)
Inventor: ODENTHAL HEINZ P
IPC: B65B29/00
Filed: 1984-02-25
Abstract: The invention relates to a method for introducing into packaging containers flexible foil packages filled with an amorphous product, in which a group of bags made up of foil packages (6) lying one on top of the other in overlapping formation is conveyed horizontally and introduced vertically into the packaging container (1) over a curved conveying section (4). According to the invention, the foil packages are conveyed flat on a conveyor belt (5) without overlap and following one another in series and transferred to an intermediate belt (7) driven at a slower transport speed, thus forming a bag group of imbricated foil packages. After a predetermined number of foil packages assigned to the packaging container (1) have been received, the intermediate belt (7) is accelerated for a short period, a bag- group section with a subsequent gap being formed. The bag-group section is introduced over the curved conveying section (4) into the packaging container (1). After the filling operation is complete, during the time interval given by the gap, the deflection element (12) is withdrawn from the packaging container (1), the packaging container (1) is transported away and the deflecting element (12) is inserted into a following, empty packaging container. <IMAGE>

Title: High-pressure, long-stroke press with cable drive
Inventor: PANTELAKIS NILOS
IPC: B30B1/30
Filed: 1984-05-23
Abstract: The fact that a cable pulled tight with a force of P will move the stationary roller and the deflection roller towards one another at 2 . P (double the force) is the basic idea behind a high-pressure surface press. The rollers are converted into jaws. In similar fashion to a multi-roller system, the said press can endlessly increase its closing force, without increasing the tensile force of the cable or the drive, if the coils enclosing the jaws are multiplied.

Title: Closure of the reactor core integrated in the small rotary closure of a fast nuclear reactor
Inventor: CAI GIULIO
IPC: G21C13/073
Filed: 1984-09-05
Abstract: The subject matter of the invention is a closure of the core of a fast reactor which is constructed to be integrated with the "small" rotating closure. In the known state of the art, the reactor core closure is mounted in the interior of the "small" rotary closure, which is rotatably mounted, as its name implies, in an eccentric position in the interior of the "large" rotary closure. 
<??>According to the invention, the core closure (20) of the reactor is constructed in one piece (10) with the "small" rotary closure, thus permitting a reduction in the end diameter of the small rotary closure on one side, and of the large rotary closure on the other side. The solution proposed by the invention is aimed at a substantial contribution in the production of fast nuclear reactors of integrated type which although fitted with a smaller and therefore economically efficient unit nevertheless have an output equal to that of the conventional reactors having a detachable core closure that is separate from the small rotary closure (Fig. 3).
