Patent EP-0451066-A1 (EP)
Inventor: VIOLI RAYMOND
IPC: F22B1/28
Filed: 1991-04-02
Abstract: The steam generator according to the invention is characterised by the presence of an intermediate duct (17) which admits the drain water into the lowest central part of the enclosure (1) of the generator and is connected to a vane pump (19), the output (20) of which delivers into an output duct (21) which rises to an upper elbow (28) and then descends to a drain duct (22). Heating tubes (8, 9, 10) bring about the evaporation of the water which they contain and the steam escapes into a horizontal upper duct (6) and then into a steam conduction duct (4). The generator finds application in particular in food cooking ovens.

Abstract: Solutions of linear aromatic poly(imideamide)s which are, on the one hand, clear at room temperature (23 DEG C) and stable in storage at the same temperature and, on the other hand, are suitable for producing especially films or varnishes exhibiting little colour. More precisely, these solutions consist: a) of  gamma -butyrolactone as solvent and b) of a particular poly(imideamide) which is prepared by reaction of an aromatic diisocyanate, a monoanhydride of a tricarboxylic acid and optionally of an aromatic diacid, while taking care, on the one hand, to use 2,4-diisocyanatotoluene and/or 2,6- diisocyanatotoluene as diisocyanate and, on the other hand, to conduct the polycondensation in the presence of a chain limiting agent consisting of benzoic acid or phthalic anhydride. The concentration of the poly(imideamide) in the  gamma -butyrolactone, expressed as weight of polymer relative to the total of polymer plus solvent, is between 5 and 40%.

Abstract: A method and apparatus allows to accurately detect voice presence on a digitized communication line even in the presence of tone signals. 
     The method includes analyzing digitized communication input signal by current blocks of 20ms (step 20), to define the stationary or non stationary state of any current block (step 21). Then an analysis on the states of the M last 20ms blocks (step 22) allows to give the final decision on voice presence or not.

Abstract: The present invention refers to a new type of leakage-proof container for ice-cream or any other product, in various capacities, made in paperboard eventually treated on one side to be resistent to the penetration of water, oil or grease, depending upon the type of products contained in it. 
     The container is made of a single paperboard blank cut and folded into a container body and a dependant hinged lid. The sides (3, 4, 13) of the container body are interconnected by gusset folds (2) in order to make them leakproof.  The lid (10) is provided with three side flaps (8, 9) which are glued to the corresponding side pannels (3, 13) of the container body and are severable therefrom along precut tearing strips (11) to gain access to the contents.  After the first opening, the container can be reclosed using a tong (12) insertable into a slit (7).

Title: Solder fluxes bearing oxide removers generated by light.
Inventor: LANDRETH BOBBY DEAN
IPC: H05K3/34
Filed: 1991-08-13
Abstract: Fluxing compositions containing compounds that generate acids upon photoinitiation from a light source such as Hg/Xe ultraviolet (UV) light sources are described. The acids clean oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water. The compounds that release an oxide removing agent, sometimes called a "photoacid" include metal and organic onium salts and furyl compounds bearing a carbonyl group. Such fluxing compositions can be used mixed with typical solder formulations, such as lead/tin solders, or applied topically thereto; both techniques permit the assembly of PCBs more easily and with high quality bonds.

Abstract: Selon un procédé de détermination des contraintes internes, on reproduit au moyen de faisceaux laser la surface de l'objet à mesurer, puis on perce à un ou plusieurs endroits déterminés un ou plusieurs orifices ayant des diamètre et profondeur déterminés et on reproduit à nouveau avec des faisceaux laser la surface pourvue d'un ou plusieurs orifices. On réunit finalement les deux images de manière à former une image holographique par interférence, à partir de laquelle on détermine les axes principaux de distribution des contraintes internes. Selon l'invention, on perce un ou plusieurs orifices jusqu'à une profondeur égale au maximum à la moitié du diamètre de l'orifice ou des orifices et on y ajoute dans un rayon égal à quatre diamètres des orifices une déformation élastique ponctuelle, par exemple en perçant un trou avec un pointeau dans la surface de l'objet à mesurer, puis on reproduit une troisième fois au moyen du faisceau laser la surface de l'objet à mesurer et on réunit l'image ainsi obtenue aux deux images précédentes, formant une image holographique commune.

Abstract: In the acquisition of marine seismic data using towed streamers, only a relatively narrow underground strip is covered. Detecting the underground without gaps therefore requires sailing over many closely neighbouring profile lines. In the measuring arrangement according to the invention and in the method, as wide as possible an underground strip is detected by means of a single sail along a profile by providing that at least one streamer (3, 5) is held at an acute offset angle ( alpha ) between its longitudinal axis and the bearing of the ship (1) and is moved through the water essentially parallel to the bearing (4), the offset angle ( alpha ) being controlled from the ship (1) in a wide angular range in order to evade obstacles. The invention is suitable for the rapid and cost-effective 3-dimensional coverage of the marine seismology of relatively large measurement areas, in particular in coastal areas and around drilling platforms. <IMAGE>

Abstract: In a chair, a seat-part support (11) and a backrest support (12), which is adjustable in inclination, are connected movably to effect a synchronous adjusting movement taking place relative to the frame (10). The backrest support engages at its lower end (12a) below the seat-part support and is connected to it for simultaneous movement by means of at least one connecting element. In a transfer movement initiated by the motion of the body of the chair-user, the backrest support is lowered while the seat-part support is simultaneously moved forwards and lowered at least in its rear part (11b). Due to the fact that the backrest support (12) and the seat-part support (11, 111, 211) transmit their movement onto the connecting means and onto one another at points on the connecting means which are spaced apart and are guided on the frame despite being bound to paths which are independent of one another, the backrest support being lowered at least slightly further than the seat-part support in the connection region to the seat-part support during the transfer into the rest position, a high-quality chair is produced in a cost-effective manner, which chair can be transferred into a rest position which is as comfortable as possible. <IMAGE>
