Patent EP-0331958-A2 (EP)
Inventor: BRUNNER RUDOLF
IPC: F15B11/16
Filed: 1989-02-20
Abstract: In a control device with at least one directional control valve connected upstream of a consumer, a pressure balance, a control-line circuit with several control lines, of which one is connected to a load-pressure tapping connection of the directional control valve, two restriction points which are arranged in the control-line circuit and the input pressures of which are transmitted to both sides of the pressure balance, and a non-return valve forming the second restriction point, the supply pressure is raised above the consumer pressure. 
<??>An essentially uniform pressure rise is obtained via the flow resistance and spring loading of the non-return valve, which pressure rise is geared to the maximum demand. At a low consumption quantity, this means an unnecessary excess of capacity in the pump line. In the novel control device, the pressure rise is to be continuously adapted automatically to the demand. In order to obtain a specific adaptation, the spring (18) of the non-return valve (19) can be preloaded in proportion to the stroke movement and infinitely at least over part of the stroke of the control member (4) of the directional control valve (3). With the infinite preloading of the spring (18), the pressure rise is adapted to the demand. 
<??>On account of the continuous adaptation, the control device is especially suitable for sensitive control systems.

Abstract: An improved decay heat removal system and apparatus for a nuclear boiling water reactor. The apparatus includes an isolation condenser shell (100), water coolant (102), and heat exchange surfaces (54, 64, 74) that are immersed in the water coolant and are sized for shutdown cooling duty. The apparatus is time shared for both isolation cooling and shutdown cooling duty. The invention re­duces the total number of heat exchange surfaces and heat exchanger shells required for dissipating heat generated by the reactor core as compared to conven­tional, separate isolation cooling and shutdown cooling systems. In addition, the amount of reactor building space which must be reserved for isolation cooling and shutdown cooling requirements may be significantly reduced.

Abstract: Louvres for light fittings serve as a mask for the light-emitting surface and as an anti-glare device in the case of elongated light fittings, and are known in several embodiments. They are mostly composed of two or more longitudinal webs and a multiplicity of thin cross-slats. With regard to specular louvres in particular, this assembly requires a substantial, overwhelmingly manual expenditure. The aim is therefore to indicate a method to enable high quality specular louvres to be produced and assembled in a largely automatic fashion. Using the method, annularly self-closed, parabolically curved louvre chambers (5) are formed as individual components which are subsequently joined to one another on a holding device (6), being juxtaposed to form several rows. A louvre for a light fitting produced in this way is suitable in particular for masking the light-emitting surface of elongated light fittings. <IMAGE>

Abstract: The invention concerns an extrusion die assembly, especially for use where accurate centering of a mandrel is important. The assembly includes the first member having a mandrel (20) projecting therefrom and an extrusion passage (22) generally in line with the mandrel (20), which extrusion passage is, at one end, of cross-section to conform with a passage carrying extrudate for the extrusion head and which merges, over its length, into an extrusion passage at the other end, at least partially surrounding the root of the mandrel. This member (20) is adjustably located in an outer member (12), which together with the mandrel defines an extrusion nozzle. Since the extrusion passage passes through the first member, it is possible to provide positioning means for the first member and the mandrel without interfering with extrudate's flow.

Abstract: The production of integrated optoelectronic modules for optical communications requires a number of difficult process steps, particularly for the passivation and the electrical isolation of the individual components. In the present method for the production of monolithic integrated optoelectronic modules, the passivation and the electrical isolation of the individual components is achieved by an epitaxially deposited semi-insulating (SI) indium phosphide layer. Instead of an SI substrate, a conducting substrate can therefore be used and this results in an improved lattice structure in the deposited layers.
