Abstract: The present invention relates to a heterologous, completely framework-free mitral valve substitute for use in the mitral or tricuspid position which ensures an improved haemodynamic effect. This mitral valve substitute takes account of the specific requirements of cardiac flow and contractility and thus extends the durability. The heterologous, completely framework-free mitral valve substitute of the present invention comprises a sutured ring (1), valve leaflets and a subvalvular apparatus which possesses new tendinous thread insertions fixed on or between two heterologous pericardiac flaps. This heart valve substitute can be obtained from heterologous mammals, e.g. pigs, sheep or cows. The pericardiac flaps used may also be made of a synthetic material. <IMAGE>

Abstract: A bump structure for bonding leads to a semi-conductor, in which the bump has a thin lower portion (32) which overlaps and seals the edges of the passivation layer (18), and a thicker upper or stem portion (38) of smaller lateral dimensions to fit within the margins of the opening in the passivation layer. Thus, during bonding, downward compressive forces are applied primarily through the bump stem directly to the metal termination pad (14) beneath the bump, and very little force is applied to the edges of the passivation layer. This reduces the likelihood of passivation layer cracking, increasing device reliability. Because the bump stem is formed within the margins of the passivation layer opening, it has a flat top, resulting in better lead bonding. <IMAGE>

Abstract: In a device for coating printing screens (16), the squeegees (13) and (14), which are each displaceable over the front surface or the rear surface of the printing screen (16) to be coated, are held in the central region of their longitudinal extents in each case by a carriage (11) and (12) respectively. The end regions of the two squeegees (13) and (14) are free. The squeegees (13) and (14) can be inserted in a holder (27) which is displaceable along guide paths (43) around the front edge of the corresponding squeegee (13) or (14). The guide paths (43) are arranged in pivotable levers (36) which are held pivotably in the carriage (11) or (12). The squeegees (13) and (14) can thus be engaged against or disengaged from the printing screen (16) and can be pivoted up. <IMAGE>

Abstract: A heat exchanger has a core assembled of integrally formed modules (11). Each module encloses channels (17) separated by strengthening webs (16) and its large, flat, external faces carry respective arrays of fins (18, 19). By stacking the modules, with facing arrays of fins interleaving, further channels (20) are formed. The enlarged surface area of channels (20) compared with channels (15) (preferably these surface areas are in a ratio of over 7:1) makes the stack of modules suitable for heat exchange between parallel counterflows of fluids of differing heat capacities. Preferred apparatus has air fan-forced, via straight manifolds, through channels (20) - the interleaved fins serving to even out air temperatures and speeds across the channels' widths - whilst the ends of channels (17) are closed and a liquid (or liquids) enters and leaves channels (17) at right angles thereto although once in the channels (17) the liquid flows in parallel counterflow to the air flow.

Abstract: On détecte le raté d'allumage des cylindres individuels d'un moteur thermique (10) en surveillant la pression d'échappement pendant chaque cycle de fonctionnement du moteur. Un signal de pression est généré par un système (20) de transducteur de pression qui est relié à un tuyau (11, 12, 13) pour les gaz d'échappement. Le signal de pression est échantillonné et numérisé pendant chaque cycle pour former un vecteur d'entrée destiné à un classificateur de configurations. Les coefficients internes prédéterminés d'un classificateur (24) qualifié permettent au classificateur de discriminer en temps réel et avec une grande précision les cylindres assurant l'allumage et les cylindres présentant des défauts d'allumage. On réduit le coût global du système en utilisant un seul transducteur de pression qui sert également dans le système de remise en circulation des gaz d'échappement du moteur thermique.

Abstract: A series of horizontally extending drainage pipes forming a grid system are located at or below the level of a plume of liquid contamination. The drainage recovery pipes skim off the surface of the water table, along with the plume of contamination. This minimizes the time required for removal of water that needs to be pumped from the ground and cleaned. Once the contaminant is pumped from the ground, it is delivered to a conventional treatment system where it is cleaned and then the cleaned water is returned back to the ground water table. This cleaned water is reintroduced over the grid system and is drawn through the soil to flush out any remaining contaminants in the soil. Once the treated water reaches the water table, the liquid contaminants are usually less dense than water and rise towards the surface of the water table. The contaminants are then removed by the grid system for treatment.

Abstract: PCT No. PCT/PL93/00012 Sec. 371 Date Dec. 18, 1995 Sec. 102(e) Date Dec. 18, 1995 PCT Filed Aug. 12, 1993 PCT Pub. No. WO95/00583 PCT Pub. Date Jan. 5, 1995This invention relates to a process for preparing ceramic-like materials with specific properties by binding an inorganic filler in the form of a dry composition with a grain size of up to 25  mu m containing in the volume ratio 1:0.-1.52 a waste phosphogypsum and magnetite or glass-forming oxides, with an unsaturated polyester resin in an amount of 46-220 volume parts per 100 volume parts of the filler. The use of magnetite makes it poisible to prepare materials with magnetic properties, while glass-foming oxides enable preparing materials effective to absorb an X-radiation of 45-55 keV and a hard radiation of 0.6-125 MeV. When an expanding agent is added to the raw composition according to this invention, an expanded material is obtained, having completely closed pores, particularly useful in the building industry. The resultant ceramic-like materials are characterized by good adhesion to metals, plastics, glass, wood, concrete and can be easily joined with them both at the stage of polymerization and after its termination by using a prepolymerized resin as a binder.

Abstract: A gamma radiation dosimeter comprises a polyester film substrate 10, of which a central circular region 12 is coated with a gamma-radiation sensitive layer 14 which is covered by an overlayer 16. The radiation-sensitive layer 14 is formed from styrene-acrylonitrile copolymer and contains 1-bromoadamantane and a leuco dye. The overlayer 16 is formed from an acrylic resin binder containing a UV-absorber. The central region 12 is surround by an annular region 18 which is divided into six equally-sized sections 18a.....18f. Each section 18a.....18f is printed in a colour which corresponds to the colour developed in the central region 14 when it has been exposed to successive increasing amounts of gamma radiation. After exposure of the device, the amount of radiation to which the device has been exposed can be determined by comparing the colour generated in the region 14 with the colours of the sections 18a.....18f. The colour of the section most closely corresponding to that of the central region indicates the dose of gamma radiation which the device, and any other object similarly exposed, has received. <IMAGE>
