The receptacle connector comprises a moulded insulating cover (1) which receives a moulded insulating base (36) carrying electrical contacts (60) for engaging contacts of a plug connector (100) inserted into a cavity (2) in the cover (1). To enable the connector to be mounted on a circuit board with the contacts (60) connected to circuitry (not shown) on the board, the contacts (60) have lead portions (64) which project beneath the base (36), the bottom of the cover (36) being open to receive the lead portions (64). Rails (48) on the base (36), which engage in grooves (82 and 88) in the cover, being provided on the sides of the base (36) and having thereon latches (50) for engaging shoulders (52A) defined by the grooves (82 and 88). In the manufacture of the connector, the contacts (60) are selectively plated with gold stripes (not shown) for engagement by the contacts of the plug (100).

The invention relates to the use of a composition comprising a chlorinated polyester resin in which the polyester satisfies formula (I) below: together with a crosslinking catalyst and a crosslinking accelerator in order to plug a crack affecting the wall of a metal device intended to contain a radioactive acid material. It is especially applicable in the maintenance of metal equipment of nuclear installations, in particular equipment that is for irradiated nuclear fuel reprocessing.

The present invention is intended to provide a glass article with a metal member joined thereto in which an electroconductive coating film is formed on at least a part of the surface of the glass article by baking a silver paste that includes Ag particles and a glass frit, a joining plane of the metal member is fixed onto the electroconductive coating film with a lead-free solder alloy containing Sn as a main component, and the lead-free solder alloy contains at least 1.5 mass% ofAg, which prevents the appearance of the electroconductive coating film and the bonding strength from degrading. Furthermore, in the present invention, when using a metal member having at least two joining planes, the total area of the joining planes is set within a range of 37 mm<2> to 50 mm<2>, which allows high bonding strength between the glass article and metal member to be maintained while using the lead-free solder alloy. Moreover, in the present invention, the volume of the lead-free solder alloy to be provided on each joining plane is set to be 1.0 to 2.0 times the product of the area of the joining plane concerned and the thickness of the lead-free solder alloy, which prevents cracks from occurring in the glass article.

The invention relates to a material for sealing porous construction surfaces against damp. The material exists in the form of plaster. Said plaster consists of a composition made of sand, cement, lime hydrate, water, metal soap, air entraining agents and a mixture of mineral substances.

The present invention concerns a means for controlling and/or measuring the flow of a running fluid, wherein the throttling of the flow is controlled utilizing the fluid's own differential pressure arising from the flow. The valve comprises a cover provided with a flow aperture, a main valve disc and control means consisting of a cylinder volume/piston assembly, the movement of said piston being connected to the main valve disc, and wherein the cylinder volume has been connected by a first opening (d1 min ) to the high pressure side and by a second opening (d2 min ) to the low pressure side so that the ratio of the areas of the openings is adjustable. The means comprises at least one sensing member by the aid of which the position of a part of the cylinder volume/piston assembly moving axially in the direction of the flow is measured; a data processing unit, to which the signal from the sensing member is conveyed after appropriate processing; a memory unit, in the first part of which have been stored data concerning the characteristic curve of the valve or equivalent, from which based on the signal from said sensing element, with the aid of the data processing unit, the variations of volumetric flow and or pressure can be calculated, and in the second part of said memory unit being stored the desired values of the volumetric flow and/or pressure, with which the calculated values mentioned before are compared; and at least one actuator by the aid of which the ratio of areas of the openings (d1 min , d2 min ) is adjustable for realizing the desired volumetric flow and/or pressure.

The invention relates to a leaky coaxial antenna (10) comprising an inner conductor (1), a dielectric (2) around the inner conductor (1), and a first shield conductor (4) disposed around the dielectric (2), the first shield conductor having openings (41) distributed in longitudinal direction of the inner conductor (1) and being adapted in that electromagnetic energy passes through the openings (41). A second shield conductor (5) is disposed around or underneath the first shield conductor (4), the second shield conductor (5) being adapted to cover or mask at least a number of the openings (41) of the first shield conductor in a shielded section (S1 - S12). The second shield conductor (5) is arranged discontinuously in the longitudinal direction of the antenna (10) defining uncovered or unmasked portions (AS1 - AS12) of the first shield conductor (4) in the longitudinal direction of the antenna which are adapted in that electromagnetic energy passes through the uncovered portions (AS1 - AS12). Thus, the present invention suggests a two-layer shield for improving the properties of a leaky coaxial antenna with respect to e.g. aerospace applications.

A device that may be applied in particular to shutters and similar and that will allow, by means of the rotation of the sole handle (28), the opening of the shutter, the orientation of movable blades (6) and the determination of the blocking in a plurality of different positions by moving rods (18) with the possibility of different interposition of metal plates (55, 56, 63, 66, 66 min ).
