Abstract: Une antenne à micro-ondes à rapiècement comprend des sous-ensembles espacés formés chacun d'une pièce d'alimentation (1) et d'au moins une paire de pièces parasites (3a, 3b) alimentées par des bords non rayonnants (selon la définition ci-incluse) de la pièce d'alimentation (1); dans un deuxième mode de réalisation, l'agencement comprend une deuxième paire de pièces parasites (3c, 3d) alimentées par les bords rayonnants, de façon à former une croix à cinq éléments. L'écart entre les pièces qui forment un groupe est maintenu au-dessous de lambda/15 et les groupes sont mutuellement écartés d'au moins deux fois cette distance. L'écart entre les groupes P est maintenu au-dessous de 2lambda, mais peut être supérieur à lambda si des lignes de pièces alternées sont décalées de P/2, de sorte qu'aucun lobe de diffraction axial n'apparaisse dans le motif de rayonnement.

Abstract: A drain value activator assembly for a container such as a bathtub (10) is disclosed. In one embodiment, there is an overflow plate mountable (17) on a side wall of the tub at the overflow outlet (21). A stem (23) is positioned through the plate so as to rotate on its own longitudinal axis, so as to have one end extending into the bathtub, and so as to have one end extending out of the bathtub. A solenoid (53) is provided outside the tub with a holding member such as a leaf spring (47). Upon activation, the solenoid (53) pulls the leaf (47) spring away from the stem. Normally, the leaf spring is biased towards the stem. The holding member and a stem end are configured so as to be able to interfit and inhibit stem rotation when the leaf spring abuts against the stem. A torsion spring (42) stores the rotational energy used to manually open the valve, and then uses that energy to drive the valve to the closed position in response to the solenoid operation.

Abstract: 2.1 To fasten expanding anchors, conventional mounting tools are used which can be put onto a drill chucked in a drill chuck of a drilling machine. …<??>2.2 So that a mounting tool which is simple in construction and manipulation can be used, a mounting unit is proposed which has a mounting tool which can be chucked directly in a drill chuck. A polygon arranged on the end face of the mounting tool engages in an inner bore adjoining the internal thread and having a reduced diameter. The expanding sleeve is thereby pushed onto the expanding body of the expanding anchor, and rapid anchoring of the expanding anchor in the drilled hole in masonry is made possible.

Abstract: The exhaust gas-driven turbocharger comprises a radial turbine (4) and a gas flow housing (3), which is divided into a main duct (10) and an auxiliary duct (11). This division is maintained right up to the outlet of a turbine guide device (14) to directly in front of the turbine rotor. By means of a shut-off device (17) the auxiliary duct (11) can be steplessly closed upstream and its cross-section is thereby withdrawn from the gas flow. In this way a reduction of the effective turbine cross-section is achieved, which leads to an increase in the turbine energy, converted on the compressor side (6) into an increase in charging pressure. <IMAGE>

Abstract: Process for concentrating an aqueous liquid containing organic compounds which are volatile or capable of being entrained with steam and optionally sugars, characterised in that it comprises a pervaporation stage which consists in bringing the said liquid into contact with the upstream face of a membrane consisting of a water-insoluble polymer absorbing water and containing from 20 to 80% by weight of polymerised and/or grafted carboxylic acid monomer units, the carboxyl groups carried by these units being wholly or partly in salt form, and maintaining, on the side of the downstream face of the membrane, a pressure lower than the partial pressure of water vapour of the said aqueous liquid to be concentrated at the temperature at which it is brought into contact with the said upstream face, so that the water in the aqueous liquid is transferred, in preference to the said organic compounds and sugars, from the upstream face to the downstream face to obtain, on the side of this downstream face, a permeate in the form of vapour essentially free from the said organic compounds and sugars and, on the side of the upstream face, a liquid aqueous retentate enriched in the said organic compounds and sugars. This process can be employed in particular for concentrating fruit juices or musts.
