Abstract: This invention relates to a device for the sealed connection of two pipe elements, wherein it comprises in projection on the pipe elements two members capable of being moved towards each other by at least one clamping means and of which the contiguous faces defined opposite grooves for housing a crushable seal comprising an inner toric ring of which the convexity is directed outwardly and an outer toric ring of which the convexity is directed inwardly. According to the invention, the seal is constituted solely by such rings, which abut on each other opposite the annular crests of their convex parts and the circular groove of each connecting member presents convergent bearing surfaces pressing the edges of said rings.

The invention overcomes such difficulty by adjoining on both sides of the elements a generally parallelepipedic relay metallized on at least two (12,13) of its adjacent faces to transpose one connection face (7) situated in plane which must be curved into one connection face (13) which is perpendicular and of which the orientation remains unchanged and parallel to a same plane during the curvature operation. As a result, the connection is simplified.

Abstract: Direct reaction of polyisocyanates and polyamines occurs vigorously and uncontrollably. It is therefore necessary to use the polyisocyanate in blocked form. In previously known processes, it has not been possible to obtain the desired semi-blocked adducts; instead, relatively large portions of completely blocked product in addition to unreacted polyisocyanate were obtained. The further reaction with polyamines was unsuccessful. 
<??>The preparation of blocked, urea-containing polyisocyanates has been made possible by using semi-blocked polyisocyanates, which are formed by the addition of blocking agent to a manifold excess of polyisocyanate, followed by thin-film distillation and subsequent reaction with polyamines in an NCO/amino group ratio of 1 to 1.3:1 to 1.1. 
<??>The blocked, urea-containing polyisocyanates are used in particular for PUR paints.

Abstract: A thermal blanket (10) includes an inflatable covering with a head end (12), a foot end (14), two edges (15) and an undersurface. The covering is inflated through an inlet (16) at the foot end (14) by a thermally-controlled inflating medium. An aperture array on the undersurface of the covering exhausts the thermally-controlled inflating medium from the covering. Exhaust port openings (23) are provided at the edges (15) of the covering to vent the inflating medium, which enhances circulation of the thermally-controlled medium through the cover. An uninflatable section (22) is provided at the head end (12), together with an absorbent bib (24) attached to the covering, adjacent the uninflatable section (22). When inflated, the thermal blanket (10) self-erects and provides a bath of thermally-controlled inflating medium to the interior of the erected structure. The enhanced circulation of the medium through the covers maintains a relatively high average temperature under the blanket (10) and a relatively uniform distribution of temperature in the inflating medium which is exhausted through the apertures into the structure's interior. When the structure covers a patient, the uninflatable section (22) provides a relatively unobstructed view of the patient's face, while the absorbent bib (24) maintains a relatively sanitary environment in the area beneath the patient's head.

Abstract: The mixed crystal layer (C, D) of metaloids on a workpiece, applied by means of reactive physical coating, has an incorporation ratio of metaloids which changes continuously in the thickness direction. The mixed crystal layer (C, D) is present on a separation layer (A) of the workpiece. For the production of the metal layer (C, D), titanium is evaporated in a crucible, which is moved to and fro in front of the workpiece surfaces to be coated, in a vacuum chamber, and two gases which have different affinities to the vaporised titanium are passed in. To produce a first part layer (C) of the mixed crystal layer (C, D), the incorporation ratio of the gases is continuously changed. During coating, the workpieces rotate so that their surface sometimes faces the crucible and sometimes faces away. The coated workpieces are distinguished by high flank wear resistance and crater wear resistance. <IMAGE>

Abstract: For determining the presence of free light chains (Bence Jones protein) in the urine there is proposed a method which calls for reacting the sample with an anti free light chain antiserum reagent where the presence of said free light chains is revealed by the turbidity of the reacted sample. By comparison with the turbidity of calibrators having predetermined concentrations it is possible to find quantitative analysis values. A kit for performance of the analysis includes anti free light chain antiserum reagent, calibrator and reagent without antiserum.

Abstract: The station, in particular a terminal, comprises an oscillator (OS) having a feedback loop (1) and a station inductor element (L10) suitable for conferring a working frequency to the oscillator which varies relative to a rest frequency. The station also includes a station processor connected to the oscillator and capable of processing variations in the working frequency of the oscillator. The portable object, in particular a memory card, includes an electronic circuit which is switchable between an inactive state and an active state in which it sets up a resonant circuit tuned on a frequency which is distinct from the rest frequency while remaining suitable for being coupled inductively with the feedback loop (1) at the rest frequency. The portable object also includes an object processor capable of switching the electronic circuit as a function of the information to be transmitted to the station. The variation in the operating frequency of the oscillator as induced in this way by the switching enables the station processor to deduce the information.
