Title: Liquid-cooled nuclear reactor
Inventor: CONRADS HERMANN-JOSEF ING GRAD
IPC: G21D1/02
Filed: 1984-05-09
Abstract: It is generally the case that a primary coolant pump (4) is situated in the coolant pipe (1) of a liquid-cooled nuclear reactor between two sections (2, 5) at different levels, because the section (2) assigned to the suction side of the pump (4) leads into the pump (4) from below and is thus situated lower than the section (5) assigned to the pressure side. Arranged between these two sections (2, 5) is an auxiliary line (14) which is situated lower and at the lowest point (26) of which a drain connection (28) is provided. The invention comes into consideration, in particular, for pressurised-water reactors. <IMAGE>

Title: Weatherproof-roof structure
Inventor: BRUYN JAN WILHELMUS DE
IPC: E04F10/00
Filed: 1984-05-15
Abstract: Hollow, essentially closed weatherproof-roof element which is made up of two shell-type individual parts and has two fastening members, each in the form of an extension, and an angled-off fastening flange at one end, the weatherproof roof having, on the rear side, two plug-in slots by means of which, once the extensions have been fastened onto the facade, it can be plugged onto the extensions. The extensions (6, 6'; 7, 7') are produced from an angle profile and the principal surface (2') of the upper shell (12) of the weatherproof roof merges, at the two sides, by way of a transition part (10), the width dimension of which is smaller than the dimension of the angle material from which the extensions are produced, into the upright border (5), such that, after the fastening, a border region of the principal surface (2') can come to bear, on both sides, on a web (7, 7') of the extension. On one side of the weatherproof roof, on the underside of the principal surface (2') of the upper shell (2), directly next to the transition part (10), there is preferably provided a strip of filling material (11), preferably plastic. The height of said strip is such that, if the weatherproof-roof element rests, with said filling-material strip at this point, on one extension (6', 7') and it rests, on the other side (12), directly with the underside of the principal surface on the other extension (6, 7), a desired gradient of the principal surface is obtained. <IMAGE>

Patent DE-3418470-A1 (DE)
Title: Elongate composite element for forming prefabricated building parts
Inventor: QUICKER HERBERT
IPC: E04B1/94
Filed: 1984-05-18
Abstract: An elongate composite element for forming prefabricated building parts, such as door and window frames, wall elements and the like, comprises metal profiled rails (2, 3) which are thermally insulated at least with respect to each other and which are fastened on each other via a non-metallic intermediate element (6) held between them in a positively locking manner. In order to avoid the profiled composite unit bursting apart as a result of the excessive, unbalanced thermal expansion of one of the profiled rails (2, 3) in the event of a fire, the positively locking connections are formed as sliding connections which can be displaced independently of one another in the longitudinal direction (8) of the profiles and which, in the temperature range below 300 DEG C, are retained in the non-displaced desired position by a sliding attachment (adhesive-bonding connection 9, screw connection 10). <IMAGE>
Patent DE-3420609-A1 (DE)
Title: Process for the separation of rubber and components fully or partially included therein
IPC: C08J11/20
Filed: 1984-06-02
Abstract: In a process for the treatment of parts which comprise rubber and components fully or partially included therein, separation of these constituents can be achieved by treating the part with mineral oil in the liquid or vapour phase at a temperature of above 150 DEG C, preferably between 180 and 320 DEG C, and subsequently mechanically separating the components made from other materials from the liquid phase and/or weakly adhering rubber residues. In a procedure in the liquid phase and the use of high-boiling mineral oils, for example used oil, increasing the temperature to from 300 to 600 DEG C allows the rubber to be converted in its entirety into a liquid, highly viscous product which can be reused in a similar way to conventional bitumen. This allows, in particular, used rubber, such as vehicle tyres, to be processed.
Patent DE-3429848-A1 (DE)
Title: Screw extruder
Inventor: KRIEGER UWE DR DIPL ING
IPC: B30B11/24
Filed: 1984-08-14
Abstract: A screw extruder having a drivable and approximately conical screw which is mounted so as to be rotatable in an extruder barrel and has a screw core and, surrounding said screw core, a screw flight, the external diameter of which decreases from the extruder feed zone towards the extruder discharge zone, and having a stationary screen casing or strainer casing adapted to the screw shape and closely surrounding the screw flight, is to be designed such that it can be used for extruding liquid-containing suspensions, in particular suspensions of fibrous material, with high efficiency. This is achieved in that the screw core is also approximately conical, the angle of inclination of the core casing and of the strainer casing approximately correspond to one another. By this means, with a short overall length and therefore low energy consumption, good values for the pressure increase necessary for extrusion and for the throughput can be obtained. It is of particular importance if a counterpressure is generated in the region of the discharge end of the screw which is close to the extruder discharge zone. It is also favourable if there is disposed between the conical screw and a pressure medium for generating the counterpressure an approximately cylindrical second screw which is preferably separate from the conical screw and rotates more slowly. This can prevent the extruded material being pressed solid and can achieve a smaller total power consumption.

Title: Method for accumulating particles and taking seawater samples in situ down to any sea depth
Inventor: KROEBEL WERNER PROF DR
IPC: G01N1/10
Filed: 1984-11-26
Abstract: In order take samples of seawater from defined or measured depths and geographic sea locations, so-called water scoops have been used for more than a 100 years. They usually have a volume of 2 l, to allow for substances contained therein still to be filtered out in suitable amounts on board ship. This method is very laborious and, if such water scoops are carried together with other probes for measuring profiles, permits the use of an only a small number of these. The present invention, in contrast, provides the possibility of using very different "samplers" in large numbers by disclosing a method with which, by underwater welding in situ, applying to a wide range of opening widths, to close containers of virtually any size and shape under water. The method consists in being able to seal the volumes, which are to be closed and which contain the water samples, by means of readily weldable sheets. Welding is effected in the process via a heating current surge through a welding wire which is covered at the points to be closed by preferably a plastic sheet, after the closure point has been firmly covered by a further sheet. The method can be used under widely varying closure conditions and also permits filtering of the seawater even under water, so that even for very low-volume sampling ... Original abstract incomplete.

Title: Instrument for monitoring the dust content of gases
Inventor: TRUEMPER-BOEDEMANN EHRHARD
IPC: G01N15/06
Filed: 1985-01-25
Abstract: An aliquot is drawn from the gas stream to be monitored via a probe having a replaceable mouthpiece. The entrained dust load is precipitated in a filter chamber onto a belt filter, as a result of which the resistance of the latter is increased. Said resistance is monitored by a contact manometer. The amount of dust associated with the operating point of the manometer was determined empirically and can be checked by removing coated pieces of filter. The amount of gas delivered during a measuring cycle terminated by the contact manometer is measured and transmitted to a microprocessor. The specific dust load calculated there can be printed, compared with a limit value or processed further in any manner required. A simple version of the instrument intended only for monitoring tasks compares, at a constant pump delivery rate, the duration of the measuring cycle with a predefined minimum time.

Title: Control device for the feed of the wheelhead of a grinding machine
Inventor: EBERMANN JOACHIM DIPL ING
IPC: B24B49/04
Filed: 1985-03-04
Abstract: The invention relates to a control device for the feed of the wheelhead of a grinding machine during grinding, having a numerical control assembly and a measuring control assembly. The object is achieved of configuring the control device such that, during reduced machining times, it automatically achieves a uniformly high accuracy of the finished dimensions irrespective of the change in diameter of the workpieces. The invention consists in interconnecting control elements, storage elements and logic elements such that initially a numerically controlled, position-controlled machining phase is carried out, and that thereafter a change into a dimensionally controlled, position-controlled end machining phase takes place as soon as the overmeasure corresponds with the slowing down path, or falls below the latter, in the feed position control circuit. During both machining phases, a summator is effective in a respectively associated, different operating method, and loads a position controller which activates the feed drive. The invention can be used for feed controls for grinding machines in order to reduce the amount of time wasted in different operating phases.

Title: Circuit arrangement for voice-controlled attenuation of two signal paths with transmission devices operating in opposite directions
Inventor: MOSES KLAUS
IPC: H04M9/10
Filed: 1985-08-13
Abstract: In the loudspeaker and hands-free device of a telephone set, voice-controlled attenuation or blocking of a first signal path is carried out depending on a signal of a second signal path, one signal path serving to transmit and the other signal path to receive signals, and the signal of the one signal path being removed upstream of the controllable amplifier looped into the signal path, equalised and fed to the controllable amplifier looped into the other signal path. An analog delay circuit is in each case looped into the signal path between the signal tapping point and the amplifier or the attenuator. Through selection of an appropriate delay time which corresponds to the transit time of the signal which initiates the attenuation or de-attenuation of the attenuators, the signal to be attenuated or de-attenuated does not reach the relevant attenuator until the attenuation or de-attenuation has been activated in the latter.
