Patent EP-0246856-A2 (EP)
Inventor: ARISTODIMOU EMILIOS
IPC: E04F15/02

Abstract: A tile for flooring or wall cladding has a relatively thin stone layer (11) bonded to a substrate made up from three sub-layers (13A, 13B and 13C) each of substantially the same shape and size as the stone layer (11). The sub-layer (13A) adjacent the stone layer (11) is aligned with the latter, the intermediate sub-layer (13B) is displaced in two directions to define two projecting tongues (16,17) from two edges, and two grooves on the opposed edges. The outer sub-layer (13C) is displaced in one direction to define a projecting tab (22) provided with fixing holes (23). The aligned sub-­layer (13A) may be omitted, if not required. 
     The tiles may be much thinner, and hence much lighter, than conventional stone slabs for flooring or wall cladding, on account of the strength imparted by the substrate. The tiles allow for invisible fixing, with the projecting tongues interlocking in the grooves of the adjacent tiles.

Abstract: A device for indicating whether a rise in temperature above a predetermined value has occurred includes a support member (3), such as a label, on which a temperature-sensitive material (1) is deposited. The material includes a large number of fracturable microcapsules containing a medium which changes from a solid state to a liquid state at the predetermined temperature value. The viscosity of the medium in its liquid state and the material of the support member are chosen such that the distance d₁ by which the medium flows across the support member after the fracturing of the microcapsules so as to activate the device is indicative of the time between activation of the device and cooling of the device to below the predetermined temperature value. If the temperature is subsequently allowed to rise above the predetermined value, the medium will again assume its liquid state and will flow further across the support member, reaching a distance of, say, d₂, thus indicating that the rise in temperature has occurred. The material may be printed on the label as a bar code, so that any rise above the predetermined temperature level will be indicated by distortion of the bar code which renders it unreadable.

Abstract: Disclosed is a vehicle wheel structure in which a tubeless pnumatic tire (3,13,23) is fitted over a wheel (1,11,21,31) and at least two walls (9,19,29,34) project in substantially radial directions from an outer circumferential surface of the wheel into the annular chamber defined between the tire and the wheel. These walls prevent the generation of standing waves or air column resonance inside the tire and thus contribute to the overall reduction of the road noise of the vehicle. The inner ends of the walls (9,19,29,34) may be either bonded to an annular member which surrounds the wheel or pivoted to a similar annular member and biased into their radial or upright positions by a spring member (37), in such a manner as not to interfere with the replacement of the tire. Alternatively, the walls (29) may consist of inflatable bags which may be inflated into radial positions and deflated into flat positions.

Abstract: Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200°C or greater. However, by utilizing the catalyst system of the present invention condensation polymers can be synthesized at much lower temperatures. These catalyst systems are comprised of (1) a silicon-phosphorus composition which contains at least one divalent oxygen atom which is bonded directly to a tetravalent silicon atom and a trivalent or pentavalent phosphorus atom; and (2) at least one acid acceptor. For example, P(OSiR₃)₃ wherein R can be an aliphatic or aromatic hydrocarbon radical, can be used in conjunction with a basic solvent as a catalyst system. Polymeric agents having pendant diphenylphosphine dichloride groups can also be used in conjunction with an acid acceptor as a catalyst system.

Abstract: A poly-Si film (53, 54, 55) is formed on a first insulating film (52) overlying a semiconductor substrate (51). A second insulating film (56) is formed on the poly-Si film (53, 54, 55). The poly-Si film (53, 54, 55) comprises a layered structure of a non-single crystal silicon film (53) having a phosphorus concent­ration of less than 5 × 10²⁰ cm⁻³ or containing no phosphor, a poly-Si film (54) having a phosphorus concentration of over 5 × 10²⁰ cm⁻³ and a poly-Si film (55) containing a phosphorus concentration of over 5 × 10²⁰ cm⁻³ or containing no phosphorus. Since non-single crystal silicon film (53) adjacent to the first insulating film (52) and poly-Si film (55) adjacent to the second insulating film (56) are made lower in their phosphorus concentration, the phosphorus in the films (53) and (55) are not diffused toward the insulating films (53) and (56), respectively. It is thus possible to improve the breakdown voltage across the first and second insulating films.

Abstract: Sample atomization for atomic absorption spectrophotometry is effected by passage through a heated, axially displaceable capillary tube (26) of a thermospray device; at least a fraction thereof is vaporized so that it emerges from one end of the capillary tube as a jet. A carrier liquid is forced through the capillary tube by a high pressure pump. In a retracted position, the outlet end of the capillary tube is disposed in a vacuum exhaust chamber (18). The sample is contained in a sample loop adapted to be connected into the flow path of the carrier liquid through an inlet valve. The capillary tube (26) then advances so that said end (28) is projected into a furnace (24) pre-heated to drying temperature. The sample is thus deposited on the inner wall of the furnace (24) whereas the vaporized carrier is drawn off. The furnace (24) is then heated to atomization temperature and subsequently cooled to the drying temperature.

Abstract: An active sub-munition part, a flechette warhead and flechettes for this are to be designed to the effect that the active part (90) transportable by means of a carrier (75) on the one hand has as low a weight as possible in the interests of transport over relatively long distances and on the other hand covers a predeterminably large target sector, in which it will be possible still to fight effectively actions against various and also semi-hard- to hard-armoured targets, even when they are in the concealed position of a natural or artificial state of protection. For this purpose, the active part (90) consists of a plurality of sub-munition warheads (51) with flechettes (60) which are first accelerated axially together with the warhead (51) by means of a rocket propulsion unit (70) and set in rotation about the warhead axis (57), whereupon a further acceleration, with the flechettes (60) being ejected from the warhead housing (52), takes place. To achieve an increased secondary effect, the flechettes (60) can have an axial cavity (95) filled with an incendiary compound (94). Flechettes (60) designed for combat against take-off runways or as ground mines have as a penetration brake a rear extension (68) projecting radially from the shank (66), in order to position elements disrupting traffic or an ignition sensor at the shank rear (59) in the vicinity of the surface. <IMAGE>

Abstract: The invention relates to a power transmission element which can be moved along an adjustment path and has one or more inertia-sensitive trigger mechanisms. This adjustable power transmission element is preferably used for motor vehicle seats which have to be securely blocked in their present position in the event of a crash. The force transmission element has two load carriers (6; 7) which can be displaced linearly with respect to one another and a sensor mass (2) which in the event of decelerations loads laminas (1) counter to the force of a sensor spring (3) in an inertia-conditioned manner. The laminas are tiltably arranged adjacent to one of the load carriers (6; 7) and upon being loaded become jammed in a non-positively engaging manner in an inclined position counter to the respective load carrier (6; 7). In normal use, the load carriers are freely displaceable with respect to one another. In the event of a crash, the two load carriers are locked with respect to one another in such a way that the forces from the first load carrier are transferred directly into the second load carrier. When in use with vehicle seats, this means that the inertia forces from the mass of the seat with the vehicle passenger are transferred into the vehicle cell without loading the seat adjustment elements. …<IMAGE>…

Abstract: A method is disclosed for determining color information in a computer image generated display in which the display is divided into a plurality of spans and each span comprises a matrix of pixels, each of the pixels being further divided into a matrix of subpixels, which method (or apparatus for performing it) allows overlapping and inner penetrating faces appearing in an image to be resolved without conflict. Faces of objects appearing in an image are resolved by a range ordering process for each span in an image. The faces are reordered into range separable groups in which a range separable group is defined as faces in which the maximum range to the most distant face in a group does not overlap the minimum range of the nearest face in another group. Each range separable group of faces is then processed on a per pixel basis for determining the color contribution of that face or group of faces to each subpixel within a pixel. In one form, the process of identifying the colors contributing to a pixel may be terminated at the end of processing of one group of faces when at least a minimum number of   subpixels within a pixel have been identified as covered by faces in the processed group. Where groups of faces cannot be divided into range separable groups, forced separation of groups can be implemented by establishing a predetermined maximum number of faces in a group or by inserting a pseudo-face within a group and breaking the groups at the pseudo-face.
