A hybrid oven (10) for cooking by both hot air impingement and microwave cooking includes a housing (14) defining a cooking chamber (16) adapted to receive a food product (12) for cooking, a hot air plenum (18) configured and dimensioned to hold a large volume of air relative to the cooking chamber (16), and a conduit (24) for selectively providing gaseous communication therebetween. Associated wi...

Prodn. of interlocking metallic parts, which slide over each other under pressure, comprises mixing a non-metallic molecular material in powder or granular form with the metal powder of the metallic particles produced in powder spray casting. This material is inert towards the metal and is resistant to temps. up to 900 degrees C. A ceramic, e.g. BaSO4 or TiO2, or C60 fullerene is added to the meta...

The proposed method involves the following steps: a loose material, preferably an expanded vermiculite with particle sizes of at least 0.05 mm, is mixed with a silicate and/or phosphate binder and consolidating agent; the mixture thus obtained is shaped into a sheet which then undergoes hot pressing at a sufficiently high temperature and pressure, and for a sufficiently long duration, to eliminate...

An image of external radiation is recorded onto an amplifying microchannel plate (3) connected to a supply voltage source (4) and is read from the side opposite the record side by scanning with an electron beam at current strength, providing the introduction of the plate channels in the saturation condition, and the recording of the image on a flat collecting electrode (5) made as a fine-structure...

A plug is provided for securing two components of an orthopedic implant where at least one of the components is formed of material softer than the material of the plug. In a preferred embodiment the components comprise concentric cups rotatable with respect to one another about an axis. The components are fixable using a plug to prevent rotation of the components with respect to each other. The in...
