Abstract: Un système et un procédé de forage dirigé contrôlé utilise une approche systématique permettant de concevoir le matériel de forage selon un plan de puits. L'angle d'inflexion (a) d'un logement (21) dévié de la verticale, relié entre le trépan (15) et un moteur de fond (25), le diamètre d'une pluralité de stabilisateurs (19, 29, 31 et 33) et le positionnement de ces stabilisateurs par rapport au trépan (15) sont sélectionnés et prédéterminés sur la base d'un plan de puits désiré. La mise en oeuvre d'un système de contrôle durant le forage (MWD) permet de suivre depuis la surface la direction du trou de sonde en cours. Les changements de direction nécessaires sont commandés depuis la surface simplement par la commande de la rotation du train de tige (27). Dans le cas d'un forage curviligne, seul le moteur de fond (25) est mis en rotation, amenant le trou de sonde (13) à suivre la courbe déterminée par l'angle d'inflexion (a) dans le logement (21) dévié de la verticale et le diamètre et l'emplacement des stabilisateurs concentriques (19, 29, 31 et 33). Dans le cas d'un forage rectiligne, le moteur de fond (25) et le train entier de tige (27) sont mis en rotation, annulant effectivement l'effet de l'angle d'inflexion (a) dans le logement (21) dévié de la verticale.

Abstract: The outside frame of a shower enclosure having a folding door (13) made of two V-shaped foldable door elements (14, 15) has a vertical frame panel (4) which is constructed as a plate-shaped fixed element, holds the folding door (13) at a distance from the adjoining room wall in the folded opening state, and also reduces the width of the folding door elements (14, 15) so that these project less far into the shower cubicle in the opening state. Furthermore, supports for bathing utensils and the like can be attached to the plate-shaped fixed element (4) and leads (11) - for example for a shower head mounted at the upper end of the fixed element - can be passed through the hollow fixed element (4). <IMAGE>

Abstract: During the laying of a marking line with the aid of at least one paint spray gun (2), profile particles (5) are introduced by means of a profile particle dispenser (4) into the marking composition (3) and thereby enveloped all round by the latter. The dimension of the profile particles (5), which are preferably reflective beads, is greater than the layer thickness of the bare painted line, so that profile elevations are formed. Subsequently, reflective beads (8) which also adhere to the profile elevations are scattered onto this profiled painted line (6), which beads thus ensure a good night visibility in wet conditions and when a water film is present, from which they project. The profile particles (5) can either be directly introduced into the jet of paints emerging from the paint spray gun (2) or, subsequent to the application of a painted line, be scattered thereon and then completely covered with marking composition by means of renewed spraying of a thin film of paint.

Abstract: The invention relates to a folding leaf which can be assembled from a rectangular blank by means of multiple folding edges (1, 1', 2, 2', 3, 3', 4, 10) intersecting at right angles and cuts (1, 2', 2'', 3'), starting from the sides (3, 4) with a rectangular central part which is surrounded by folding sections in the direction of the edges and corners. In the unfolded state of such a folding leaf, different folding sections can be assigned to each other, some of which belong to the front and some to the back of the folding leaf. In order to increase these possibilities of assignment, the invention provides that the central part possesses folding edges (1, 2), intersecting in the middle thereof, between two opposing cuts (1', 2'), and that one of the two folding edges of the folding sections (3') near the corners is cut open. In this manner, book-like foldings can be formed, in which the individual leaves can be combined with each other in an alternating, and hence varied, manner by appropriate folding and refolding.

Inventor: CAMPBELL ARTHUR LEE
IPC: C07F7/22
Filed: 1988-06-06
Abstract: This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as epoxide addition. The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex. This process permits the  in situ  preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction. Higher order cuprate complexes derived from the reaction of a cuprate complex with 1,2-bis-tri-n-­butylstannyl ethylene are particularly useful for the addition to epoxides to form vinyl tin intermediates useful for preparing omega side chains of prostaglandins.
