Inventor: ASHEIM HARALD ARE
IPC: E21B43/34
Filed: 1986-09-17
Abstract: Dispositif permettant de collecter des bouchons de liquide dans un pipe-line transportant du gaz (collecteurs de bouchons), notamment dans le contexte de l'exploitation de gisements pétroliers et gazeux offshore. Le pipe-line mène le long du front marin à une unité d'admission au-dessus de l'eau, en général une plate-forme. Le pipe-line est également relié à une seconde colonne montante (14) qui présente une section inférieure à celle du pipe-line principal (12). Ce dernier aboutit à une boucle (15) le long du front marin à partir de la jonction de sorte que la longueur est suffisante pour loger un bouchon et le retarder. La colonne montante (14) est équipée d'un étrangleur de régulation (22) qui peut fournir une contre-pression pour vider le liquide dans le pipe-line principal.

IPC: H01R13/658
Filed: 1987-01-27
Abstract: In order to prevent electromagnetic waves penetrating into a connector part, as interference radiation, before or during the connection of the connector parts (C1, C2), the opening of this connector part (C2) is sealed with a protective wall (18) which opens automatically when the connector parts are plugged into each other, once the housings (2,11) have overlapped each other. It is not possible to open the connector part (C2) until the external screening of the electrical parts has been completed by the housings (2,11) engaging in each other. In this way, interference signals in the leads from scattered electromagnetic waves are avoided. <IMAGE>

Abstract: This memory consists of the memory cell array (zf) with the n signal branches (b1...bn), in each one of which the m storage cells (c...) are provided. The first, second or, respectively mth storage cells (c..1, c..2, c..m-1, c..m) are in each case associated with the first, second, mth clock driver (tt1, tt2, 'ttm-1, ttm) which are selected by the fundamental clock signal (g1) and other signals. This FIFO memory makes it possible to guide an input data stream occurring at an input data rate (g2) through the FIFO memory in such a manner that the output data stream to be picked up at the output (da) can be picked up at an output data rate (g3) which is instantaneously different from the input data rate (g2), the two data rates, however, being equal averaged over time so that the FIFO memory can be read and loaded at the same time at different data rates. …<IMAGE>…

IPC: G01S3/32
Filed: 1987-02-26
Abstract: In a direction-finding antenna system comprising an array of elements (1-8) mutually spaced in at least one direction and feeder means for forming sum and difference radiation patterns, the contribution of outer elements (1,5;4,8) lying beyond the phase centres of the sub-arrays from which the sum pattern is formed, relative to the contribution of inner elements (2,6;3,7), is less to the difference pattern than to the sum pattern, in order that the magnitude of the difference pattern should exceed that of the sum pattern except in the region of the central null in the difference pattern. The invention is particularly applicable to a curved array of relatively small aperture, such as an IFF array mounted on a parabolic radar antenna reflector operating at a much higher frequency.

Abstract: A process is disclosed for the production of high quality benzene (12) and a desired xylene isomer, prefer­ably paraxylene (29), from a mixture of C₇-plus alkylaro­matic hydrocarbons (1). The desired xylene isomer is recovered by separation (28) from a stream (20) of two or three xylene isomers. the resultant isomer-depleted stream (30) is passed into an isomerization/transalkylation zone (6) together with both feed and recycled toluene and C₉ aromatic hydrocarbons (31,27,3) instead of being passed into a xylene isomerization zone. Benzene (12) and xylenes (16) are fractionated (8,11,14) from the iso­merization/transalkylation zone effluent stream (7), with the xylenes (16) being passed into the separation zone (28). A nonmetal catalyst is employed in the isomerizat­ion/transalkylation zone, which must be operated at high severity (high temperature) conditions.

Abstract: The invention relates to a device for positioning an exploratory probe in space, for example an ultrasonic probe. This device comprises an essentially rigid arm (20) whose first end (21) is articulated relative to a support holder (10) by two perpendicular articulation spindles (24, 26) and the exploratory probe (2) is mounted on a support element (30) connected to the second end (22) of the arm by at least two articulation spindles (32, 34). The support element (30) of the exploratory probe is connected to the second end (22) of the arm by means of a set of four articulation spindles (32, 34, 36, 38) which are successively disposed perpendicular to each other and in space in such a manner as to occupy a limited volume in the immediate vicinity of the exploratory probe. This device thus offers an ability for unlimited positioning in space of the exploratory probe within a space or volume which is limited or confined, which constitutes an essential technical advantage for locating targets such as concretions, renal or biliary calculi with a view to their destruction. <IMAGE>
