Patent EP-0296357-A1 (EP)
Inventor: HANNERZ KARE
IPC: F22B21/30
Filed: 1988-05-18
Abstract: Steam generator for a pressurized water reactor comprising means for supply and return of hot water from and to the re­actor for heating of feed water for steam generation, and means for supply of said feed water and removal of the steam generated. According to the invention bundles of U-shaped tubes (1) are arranged to be traversed by feed water, which bundles are located around a riser (8) for hot water from the reactor. The hot water for heating the feed water is adapted to be supplied from above (3) at one of the upper ends of the tube bundles, and, after flowing along the tubes (1), the hot water is led away from the other upper end of the tube bundles via at least one vertical gap (6) extending downwards between the tube bundles the lower end of said gap being connected to a passage way back to the reactor. The design facilitates inspection and repair because servicing of the steam generating tubes can be fully performed with access from one side only to the steam generator.

Abstract: A safety device (1) for pneumatic suspensions (2) comprises a flange (14) fixed under a sprung mass (4) and having an opening (15) around which is tightened the edge (8b) of a membrane (8) interposed between the sprung mass (4) and an unsprung mass (3), forming thus an enclosure (9) filled with a fluid under pressure. 
     A movable cap (19) is slidably guided vertically in the opening (15). A sealing element (22) is provided between the cap (19) and the flange (14). During normal working conditions the cap (19) is pushed towards the sprung mass (4) by the fluid pressure, against a spring (28) placed between the cap (19) and a plate (18) fixed to the sprung mass (4). Should the membrane burst, the cap (19) would be pushed by spring (28) against a checking element (11a) connected to the unsprung mass (3).

Abstract: The invention relates to a weft insertion device for pneumatic looms having flush-disposed main insertion nozzles, a funnel-shaped alignment aid and a guide channel along the reed. In contradistinction to existing devices of this kind, the invention provides that only the insertion nozzles be pivoted together with the reed in the course of the beating-up of the weft thread, whereas the alignment aid is fixed and its funnel-shaped, tapered opening for the weft thread is constructed as a slot which extends over part of the pivot path of the guide channel provided at the reed and which is also open in the direction of the weft thread shears. Since the components are close together in the weft direction, the weft thread drop is kept to a minimum. The effectiveness of the weft thread shears is in no way impaired and the time available for weft insertion is increased or the weaving rate of the loom can be increased. …<IMAGE>…

Abstract: The machine comprises K different signal channels. The signals are converted into the form of digital samples by K analogue-digital convertors (81 to 8K) connected respectively to each one of the channels. N monolithic elementary processors (11 to 1N) are connected by means of a sample-acquisition bus (7) which is common to all K analogue-digital convertors (81 to 8K). They are also connected by a ring bus (2) common to all the processors (11 to 1N) in order to allow results from computation carried out on the samples received by each processor to be circulated among the latter. A control unit (3) and at least one transfer controller (6), which are synchronised by a common clock signal, control respectively, on the one hand, execution of the computations to be performed by the processors (11 to 1N) on the samples which they receive, as well as on the other hand, transfer of the samples to the acquisition bus (7) and transfer of the computation results between processors over the ring bus (2). …<??>Application: radio receivers. …<IMAGE>…

Abstract: A transporter (102) for use in a weaving shed divides into two driving units (1a,1b) and a carrying unit (2). The carrying unit is on the one hand slidable and sinkable relative to the driving units and on the other can be rigidly coupled to the driving units (1a,1b). During movement of the transporter, the three units (1a,1b,2) are rigidly connected to one another, while, prior to loading with a cloth beam (50) from a loom (500), the carrying unit (2) is released from the driving units (1a,1b) to such an extent that it can be set down on the floor of the weaving shed. This achieves a precise working position of the carrying unit (2) relative to a loom (500) without the entire transporter (102) having to be exactly guided during its movement. In addition, the sinking of the carrying unit (2) onto the floor of the weaving shed results in higher stability on the extension of props (30a,30b) when an eccentric load, for example the cloth beam (50), is being removed by the carrying unit (2) from the loom (500) by means of gripper arms (40a,40b). <IMAGE>

Abstract: La machine à rotors hélicoïdaux décrite comprend une paire de rotors (3) s'engrenant, qui comportent des faces hélicoïdales et des rainures interposées, et un logement présentant un espace utile généralement composé de deux alésages s'entrecoupant renfermant chacun l'un des rotors (3). Chaque rotor (3) comprend une partie saillante cylindrique (9) qui traverse un trou (8) ménagé dans une paroi terminale (5) à l'extrémité sous haute pression de la machine pour entrer dans une chambre d'appui. Afin d'empêcher les fuites de gaz depuis l'espace utile vers la chambre d'appui, on prévoit un élément annulaire (15; 23) qui entoure chaque partie saillante (9) des rotors et qui est fixé de façon non rotative au logement. L'élément annulaire est pourvu d'une surface d'étanchéité axiale (19; 24) et d'une surface d'étanchéité radiale (20; 21) dont l'une (19; 21) coopère avec le logement et l'autre (20; 24) coopère avec la partie saillante (9) des rotors avec une force de contact légère ou égale à zéro. L'élément annulaire (15; 23) se déplace presque sans friction dans la direction de cette force de contact. Etant donné que l'élément annulaire (15; 23) n'est pourvu que d'une surface d'étanchéité radiale (20; 21), qui coopère avec la partie saillante (9) des rotors ou avec le logement, l'élément annulaire assure une fermeture étanche efficace même si l'axe du trou (8) ménagé dans la paroi terminale (5) et l'axe de la partie saillante (9) des rotors ne sont pas alignés.

Abstract: Analysis of the content of certain elements in a continuous flow of bulk materials by neutron bombardment and measurement of the gamma radiation emitted by these elements, which makes it possible to distinguish between the capture radiation and the activation radiation. The neutron source is a neutron-generating tube (7) which is activated periodically. The signals from a single gamma radiation detector (10) are considered only after neutron emission has ceased, during distinct intervals corresponding respectively to the phenomena of capture and radiation of the activated elements. The respective signals are treated in two distinct measurement routes and the results are then combined automatically. A third measurement route can be provided for gamma radiation resulting from inelastic shocks. The source (7) and the detector (10) are grouped in a probe (6) lodged in a polyethylene protective tube (5) inside the flow of the materials (1). The installation is used to analyse large flows of minerals without taking samples, in particular in the mining, coal mining, cement, and aluminium industries.

The resonance circuit of the Power Supply contains a transformer (Tr), the secondary side of which is connected to the magnetron (M) via a voltage multiplier in the shape of a rectifier and voltage doubler circuit (C3, C4, D3, D4). In order to obtain a feed-back signal, which is a measure of the power fed to the magnetron in order to enable regulation of this power, a current transformer (ST) is connected in series with one of the diodes (D3) in the rectifier and voltage doubler circuit. The output signal of the current transformer (ST) is compared with a reference signal and the result of the comparison is used to control the switch frequency and thereby the power.
