Date Jan. 26, 1989.It is well known that the use of the blowing agent monofluortrichlormethane, also called Freon 11 or R-11, for the production of polyurethane foam is highly disadvantageous in that R-11 has a decomposing effect on the ozone layer around our p...

A device for detecting differences in color of a material to be inspected, which device comprises a first light source emitting light of a first color and a second light source emitting light of a second color, an optical system adapted to project portions of the light emitted both by the first and the second light source onto first and second spaced apart measuring regions respectively, each meas...

Apparatus comprises a rotatable member 2 situated in a pressurized or evacuated chamber, means for generating an electric field at the edge of the member e.g. ring electrode 5 having sufficient strength to overcome the surface tension of the metal, and liquid metal delivery means 14 directing liquid metal onto a surface 3 of the member over which the metal flows toward the edge as the member is sp...

A seal for bearings of the hubs of vehicle wheels comprises a central body (14) rigidly connected to a metal insert (15) driven onto the outer race (11) of the bearing; extending from the body is a projection (16) which is compressed on the outer race to form a static seal thereon; also extending from the body (14) are: a dirt guard lip (17) which creates a labyrinth seal with the toroidally shape...

A seal for bearings of the hubs of vehicle wheels comprises a central body (14) having a seating recess for a spring (15), from which there extends an appendix (16) rigidly connected to a metal insert (18) driven onto the outer race (11) of the bearing; projecting from the appendix (16) is a lip (19) which provides a static seal against the outer race of the bearing, whilst two further lips (22 an...

A tile or other building product is manufactured by firing a green product from a coarse component such as metallurgical slag or crushed rock and a fine component such as fly ash, with sodium silicate or other alkali metal compound which reacts with at least the fine component to form a binding matrix.

A process and composition for applying and bonding an amine curable polymer or prepolymer at ambient temperatures to the surface of a cured elastomer substrate. The elastomer article or substrate is treated with an organic oxidant such as an N-halohydantoin, N-haloamide, or an N-haloimide, for example, the various isomers of mono-, di-, and trichloroisocyanuric acid. A polyisocyanate is applied th...

A resource allocation system for indicating the optimum allocation of a resource between a series of demands iteratively processes the probability data for each demand to determine for each of a range of amounts of resource available the optimum distribution of the resource between the demands and the resultant probability of successfully overcoming all the demands. The system may be used to predi...

A method is provided for making measurements in geological formations from a horizontal borehole or a borehole with limited slant with respect to the horizontal, formed in the wall of an underground way. It includes essentially a probe containing measuring instruments, adapted to be introduced and pushed into the borehole at the end of an elongate element such as a semirigid tube which is wound of...
