A joint prosthesis having a femoral element (16), a tibial element (12) and a bearing (20) for articulation therebetween is disclosed to further include an intermediate element (22). The intermediate element permits rotation of the bearing with respect to the tibial element and longitudinal translation of the bearing with respect to the intermediate element. Transverse translation of the bearing w...

The disclosure relates to an apparatus for the ultrasonic sealing of thermoplastic materials and comprises a vibration generator (2) of a so-called giant magnetostrictive powder composite (GMPC) which is secured in a jaw and has been given a cross-sectional area which progressively reduces seen from the anchorage point and whose free end displays a narrow working surface. The vibration generator (...

A modular plastic conveyor belt with a plurality of modules (12) with interfitting link ends (14,16,18), connected by pivot rods (22) has a rod-retention system with a slidable pivot rod hole blocking member (30) which is inserted from the bottom of the outermost link end (28) of an edge module and is captured in the edge module after insertion while being slidable to blocking and non-blocking pos...

A method is disclosed for heating pre-expanded foundry pattern molding beads of polystyrene or the like in a stream of hot air to reduce the vapor-forming expansion agent content for the purpose of producing more dimensionally accurate, molded foam bead casting patterns.

The present invention provides a non-rusting unitary co-extruded article, which may be used for a variety of purposes, including a seal. The co-extruded article includes at least two dissimilar discrete parts such as a rubber component, referred to herein as the "rubber extrudate," and a thermoplastic component, referred to herein as the "plastic extrudate." A particular advantage of the invention...

A check of the observance of prescribed transmission bit rates in an ATM switching equipment occurs using counter devices (RAM1, ALU) working according to the "leaky bucket" principle. These are individual allocated to virtual connections via the switching equipment (VA). The momentary counter readings of these counter devices are respectively decremented by a variable count value only upon arriva...

The present invention relates to mineral fibre composition which can dissolve in contact with a physiological medium. The composition of these fibres includes the following components, in accordance with the following proportions by weight: - SiO2 48 to 67% - Al2O3 0 to 8% - Fe2O3 0 to 12% - (total iron expressed in this form) - CaO 16 to 35% - MgO 1 to 16% - Na2O + K2O 0 to 6.5% - P2O5 0 to ...

A hollow rotor 10 is provided, with its axis A of rotation vertical that forms inside it a sealed chamber 11 for centrifuging the product; in the chamber 11 is placed a number of conical discs 12, parallel to each other, coaxial and attached to the rotor 10, working together to separate the phases of the product; the rotor 10 and the conical discs 12 are caused to rotate about the axis A of the ro...

In the production of ceramic shells from aqueous suspensions the combination of products which are already known in the field of ceramic shells (but not intended for the production of microcrystalline or monodirectional metal components), together with a special coating sequence and special drying and sintering procedures, makes it possible to achieve significant reductions in overall production t...

The composition provides for use of the trimethyl ester of phosphoric acid as a release agent for cast acrylic sheets for sanitary articles.

The device constructed, which forms a single part with weightlifting belt C, or which is separate and can be fitted on the said belt, comprises a structure 1 equipped with inclined evaginations 2, 3 and 4 which act on the spinal apophysis A and transverse apophysis AT.

The composition of a mixture based on methyl methacrylate (MMA) is cast in flat or cylindrical containing cells in order to obtain sheets and/or cylindrical pipes of polymethacrylate (PMMA) which exhibit a dual opal and transparent effect at the same time. The said sheets and pipes have application in the manufacture of lighting schemes and fittings, luminous signs, warning signs and objects obtai...

The process makes it possible to produce wood/concrete and light alloy manufactures impregnated with methyl methacrylate MMA and its comonomers by predrying performed using a mixed hot air/microwave system with polymerisation under the pressure of an inert gas (CO2) with high temperature catalysts so as to obtain stabilised manufactures having a high impregnation coefficient and much superior chem...

The process uses methacrylate polymer known as an organic acrylic glass to make flat sheets of glassy appearance of synthetic thermoplastic material similar to inorganic silicate sheets having transparent and opal polychrome effects.

The intravenous administration if a bolus of 3-5 grams L-carnitine or a pharmacologically acceptable salt thereof followed by 3-5 grams of L-carnitine or salt thereof vis slow infusion in about 12 hours, dramatically restore to normal the arterial pressure and respiratory frequency in a patient exhibiting serious cardiogenic or septic shock conditions.
