Abstract: By means of a device for connecting pipes of water-soluble material which can be inserted into wells and filled with bentonite or the like, with a coupling receiving element at one pipe-section end and a coupling engagement element, corresponding to the coupling receiving element, at the other pipe-section end, a solution is to be provided with which problem-free insertion of drilling sections of this type in the well bottom is possible with simple means. This is achieved in that both elements (7, 8) are essentially of pot-shaped design with one cylindrical casing each which projects into the interior of the pipe section (5) and can be secured in position there, and in that the pot base (9 or 10) has at least one passage opening (11 or 12, respectively). <IMAGE>

Abstract: A papermaking fabric has a reinforcement against attrition in the marginal edges in the form of a plastic composition which is applied to the running surface and which partially covers the edge region of the fabric. The plastic composition (3) is applied in an irregular net-shaped pattern with an open area of about 30% to the running side. To apply the plastic composition (3), a molten plastic rope extruded from a die is pulverised and atomised by air jets impinging from the side and thus sprayed onto the running side of the papermaking fabric. <IMAGE>

Abstract: Un dispositif (10) servant à stériliser des verres de contact (22) ou des objets similaires comprend un appareil de réaction (12) contenant les verres de contact et les maintenant, pour les stériliser, en contact avec une solution de peroxyde d'hydrogène (18) et deux éléments catalytiques (44, 46) utilisés pour décomposer le peroxyde d'hydrogène pendant la stérilisation des verres de contact. Le premier élément catalytique (44) décompose une partie de la concentration initiale de peroxyde d'hydrogène dans la solution, pendant la stérilisation des verres de contact. Le second élément catalytique (46) accélère la décomposition combinée de la concentration réduite de peroxyde d'hydrogène dans la solution résultant de la décomposition effectuée par le premier élément catalytique (44). Ce système permet d'obtenir une concentration de peroxyde d'hydrogène terminale, c'est-à-dire à la fin du processus de stérilisation des verres de contact, suffisamment réduite pour que lesdits verres puissent être mis en contact avec les yeux de l'utilisateur sans risque, même si des résidus de peroxyde d'hydrogène, à la concentration terminale, adhèrent aux verres de contact stérilisés.

Abstract: A multiple-pulse RF pulse sequence reduces homonuclear dipolar coupling more efficiently relative to other known pulse sequences and is relatively insensitive to inhomogeneous RF fields, pulse imperfections and transmitter misadjustments so that it can be used on less sophisticated instruments and does not require long setup times. 
     More particularly, the inventive RF pulse sequence is constructed from selected sets of known six-pulse cycles called dipolar decoupled inversion pulses or composite inversion pulses. The dipolar decoupled inversion pulses are, in turn, constructed from standard solid echo pulse pairs. The six-pulse cycles are selected so that zero-order term of the average dipolar Hamiltonian is zero.

Abstract: A method and apparatus performs detection of an edge and detection of holes or other data patterns on a tape or other magnetic or optical medium. An array of photodetectors in an integrated circuit chip senses the intensity of light illuminating the chip with the tape running between a light source and the photodetectors. The holes or the other data patterns are sensed on the tape based on a comparison between detected light intensities with a programmable reference level. In addition, areas which may normally be sensed as a hole are discarded if these areas fall within a specified tolerance.
