IPC: A61K9/00
Filed: 1985-04-17
Abstract: Procédés contraceptifs pour des animaux vivants (y compris les êtres humains) où un capuchon ou disque (10) à base de matériau cellulaire forme une matrice porteuse inerte pour soutenir des préparations contraceptives, le capuchon ou disque (10) pouvant s'engager avec l'os externe du canal cervical. La préparation contraceptive contenant des cations métalliques bivalents ou trivalents et de l'acide N-ascorbique et/ou de la neuraminidase amène le mucus cervical entrant en contact avec la dose à passer d'une structure cellulaire ouverte trouvée au milieu du cycle de la période menstruelle à une structure cellulaire fermée formant une barrière impénétrable pour les spermatozoïdes. Cette préparation contraceptive peut en outre comporter de l'asialoglycoprotéine servant d'accepteur pour l'acide sialique des spermatozoïdes afin d'empêcher la pénétration et la fertilisation des ovules par les spermatozoïdes. Ces préparations ont une autre propriété contraceptive: elles peuvent être spermotoxiques, provoquant la reformation du plasma séminal afin de piéger les spermatozoïdes, entraînant leur mort en raison de l'acidité du vagin (16).

Abstract: Molded bodies of SiC ceramic can be firmly bonded to each other or to molded bodies of other ceramic material or to metal workpieces by the establishment of diffusion-welding conditions when a metal alloy layer is interposed between cleaned and polished surfaces that are to be joined. The alloy metal of the layer is MnCu or MnCo or multi-component alloys containing the foregoing as a base and additions of other metals to a total percentage not exceeding 70% with each single other metal being present in the range from 2 to 45% by weight. Such other metals constitute 1 or more of Cr, Ti, Zr, Fe, Ni, V and Ta. The Mn, Cu alloy or alloy base has a Cu content from 10 to 90%, preferably 25 to 82% and the MnCo alloy or alloy base has a cobalt content of 5 to 50% by weight. MnCuFe eutectic compositions containing 5 to 30% by weight Fe and 10 to 90% by weight Cu and MnCoCr eutectic compositions with chromium content from 2 to 45% by weight are preferred, especially 50:40:10 MnCuFe and 60:30:10 MnCoCr. Preferred alloy metal layer thickness is from 5 to 200  mu m, especially about 10 to 50  mu m. In the case of SiSiC bodies, a preliminary treatment to convert free silicon at or near the surface to be joined into silicon nitride or silicon carbide is desirable. The provision of the alloy metal layer between the surfaces to be joined may be performed by interposing an alloy metal foil between the surfaces or by sputtering or vapor-deposition of the alloy on a silicon carbide surface to be joined. The diffusion welding is performed at a temperature lower than the melting point of the alloy layer by 20 DEG  to 300 DEG  C. while the surfaces to be joined are pressed together with a force of from 0.5 to 60 MPa.

Abstract: A sampled synchronous transmission signal Vt is represented by a series of samples J at equidistant sampling instants. A computing circuit 5 computes the po­sitions R of the sampling instants relative to the rising edges of a virtual reference clock Cref which is phase-­locked to the channel clock. For each sampling instant the position R is determined on the basis of the position R of a preceding sampling instant and a measure Q of the dif­ference in time between the sampling interval T and the period L of the virtual reference clock Cref. From the values of the successive samples J an interpolation circuit 2 derives the positions N of the detection-level crossings by the transmission signal Vt, which crosssings represent a fixed phase position of the channel clock. After each detections-level crossing the measure Q of the time diffe­rence is corrected by means of circuit 3 and 4 depending on the difference between the positions N and R. A data recovery arrangement recovers the data depending on the values determined for the positions R.

Abstract: By using an electrostatic magnetic dispersing field adapted for that purpose in a measuring space in an electron microscope it is possible to detect sub­stantially all the electrons liberated by a primary beam from a surface of an object to be examined in which the measuring field can be increased without any error by using a variable-axis lens system at the area. Auger electrons can be detected selectively by an adapted field strength variation of the magnetic field and superposition of an electrostatic retarding field. A magnetic lens for generating the magnetic field may also be used with only small adaptations as an objective lens for the elec­tron microscope.

Abstract: A pillar tap has a main water chamber 4 and a control chamber 10 housed within the main chamber 4. The control chamber 10 has two different sized openings. The smaller opening which is located opposite the main outlet valve seat 8 of the main chamber supports a membrane 12. The membrane 12 in turn supports a valve member 14 for movement into and out of engagement with the valve seat 8. 
     The larger of the two openings is closed by a resilient diaphragm 32. A pair of control valves 15 and 22 control the admission and release of water to and from the control chamber 10. 
     By controlling the control valves 16 and 22 the pressure differential between the main and control chambers 4 and 10 can be varied and so used to control the degree to which the valve member 14 is opened. 
     Once the flow rate through valve seat 8 has been set, the diaphragm 32 responds to pressure variations in the main chamber 4 to alter the position of the valve member 14 in a sense to maintain a substantially constant flow rate irrespective of the pressure variations.
