A method of making self-supporting ceramic composite structures having filler embedded therein includes infiltrating a permeable mass of filler with polycrystalline material comprising an oxidation reaction product obtained by oxidation of a parent metal such as aluminum and optionally containing therein non-oxidized constituents of the parent metal. The structure is formed by placing a parent met...

An optical head device has a light source (8) for emitting a light, a polarizing element (110A) for converting the linearly polarized emitted light into a concentric-circle polarized light or a radially polarized light, a concentric grating coupler (4B) through which the polarized light is introduced into a wavegudie layer (100), and another polarizing element (110B) for converting the light radia...

A working fluid comprising tetrafluoroethane, difluoroethane and at least one fluorinated hydrocarbon having a boiling point of not higher than -40 DEG C under atmospheric pressure selected from the group consisting of methane derivatives and ethane derivatives which consist of one or two carbon atoms, hydrogen atoms and fluorine atoms, which has very small influence on the ozone layer in the stra...

A working fluid comprising tetrafluoroethane and at least two fluorinated hydrocarbons having a boiling point of not higher than -40 DEG C under atmospheric pressure selected from the group consisting of methane derivatives and ethane derivatives which consist of one or two carbon atoms, hydrogen atoms and fluorine atoms, which has very small influence on the ozone layer in the stratosphere and is...

The supporting walls (2,3) of the mounting shaft (1) are made of metal and the second shuttering section contains at least one heat insulating component (5a,5b,6,7,8,11). A heat insulating component of the second shuttering section (B) is pref. adhered to the outside of the rear wall of the mounting shaft. An L-shaped profiled wall part and a flat wall part are assembled to form a U-shaped mountin...

A method of producing self-supporting ceramic bodies (12) having a polymer component, which includes first providing a self-supporting ceramic body (12) comprising (i) a polycrystalline oxidation reaction product formed upon oxidation of a molten parent metal with an oxidant, and (ii) interconnected porosity (13) at least partially accessible from one or more surfaces of said ceramic body. The pol...

In a container (1) of flexible material and including a tube-shaped blank divided into two opposite side walls (5) and two intermediate pairs of gusset walls (6) by means of gussets (2, 3), and having at least one block bottom (8, 9), a tightly sealed, outwardly folding discharge valve (11) is provided in the block bottom (8), said discharge valve being resealable and provided with a gripping mean...

Hydraulic actuating unit (4), in particular for raising a load, such as a hospital bed, comprising a reservoir (13) for hydraulic fluid and a hydraulic piston cylinder device (10), the cylinder of the latter having its end connected to the reservoir (13) through a supply conduit (11) containing a hydraulic plunger pump (12) with section and pressure valve means (12a, 12b) and through a return cond...

A feed accelerator system for use in a centrifuge, the system comprising a conveyor hub rotatably mounted within a rotating bowl, the hub including an inside surface and an outside surface. At least one feed slurry passageway is disposed between the inside surface of conveyor hub and the outside surface of the conveyor hub, and at least one helical blade having a plurality of turns is mounted to t...

Telephonist workstations are included in a telephone exchange 6, telecommunications station, etc., where connection apparatus functions are comprised in or are connected to computer equipment 15.

An antimicrobial composition for topical use or for incorporation into a coating or structural composition comprises an antimicrobial silver compound, preferably silver chloride, deposited on a physiologically inert oxidic synthetic particulate support material. A preferred support material is titania containing one or more of the crystalline forms anatase, rutile, and brookite.

A hydraulic elevator buffer includes a fluid container 16 containing a piston 12 which is pushed down within a cylinder 18 into a volume of hydraulic fluid. The buffer has no seals separating its interior from the atmosphere. As the piston 12 is pushed down, the displaced liquid is forced through ports 18a in the cylinder 18 which gives rise to a restricting force. The displaced liquid escapes int...
