Abstract: An apparatus and method for making a mold or mold face includes a container having at least one opening. The apparatus also includes a flexible membrane that is retained to the container that extends across the opening of the container. The apparatus for making a mold further includes support media that is disposed within the container along with a vacuum valve that is connected to the container.

Abstract: A method for improving isomerization properties of ferrierite catalysts by the use of an aqueous method treatment is disclosed.

Abstract: A watering device includes a sprinkler member having a plurality of sprinkling orifices configured to distribute a fluid over a coverage area during a sprinkling mode and at least one setup orifice configured to direct a stream of the fluid substantially along a boundary of the coverage area during a setup mode. A valve member operates between a first position to direct a supply of the fluid to the setup orifice during the setup mode and a second position to direct a supply of the fluid to the sprinkling orifices during the sprinkling mode.

Abstract: A screen assembly for partially obstructing a doorway or opening in an office cubicle comprises a screen member formed of flexible laminar material. A spring-loaded roll assembly retractably stores the screen member in a rolled fashion about its vertical axis. At least one non-marring fastener is secured to the roll assembly for releasably securing the roll assembly to the vertically extending edge of one of the upstanding walls of the office cubicle. A latch is operably associated with the screen member for selectively securing the screen member across the opening.

Abstract: Reaction injection molded (RIM) members and a method for forming such members are provided. The members can be formed in a mold cavity defining a contour that corresponds to the desired contour of the members. A foam material, such as a combination of polyol and isocyanate is injected into the cavity with a blowing agent so that the foam material expands to form the low density member. The average density of the member can be less than about 6 pounds per cubic foot.

Abstract: A mobile platform interior panel is provided that includes a body formed by a low pressure injection process and at least one of a duct and a layer of insulation integrated with the body. The low pressure injection process allows the duct and insulation to be integrated with the body simultaneously with the forming of the panel. More specifically, the duct is integrated with the panel by forming at least one internal cavity within the panel as the panel is formed. Additionally, the insulation is integrated with the panel by forming the panel using a low pressure injection material having desired insulative properties.

Abstract: Ligands for radiopharmaceutical use are capable of chelating radiometal species and of being bound to biological targeting molecules. The ligands have formula (a) and (b), where A, A'=--SZ or Y, B.dbd.O or S, Y.dbd. (c), Z.dbd.H or a thiol protecting group, m=2 or 3, n=2 or 3, q=0 or 1, R.dbd.H or unsubstituted or substituted hydrocarbon and pharmaceutically acceptable salts, provided that at least one CR.sub.2 group represents CO and forms, together with an adjacent N atom, a --CONR-- amide group.

Abstract: A continuously variable control device, e.g. a volume control in an amplifier, is so designed that after being set to a desired condition by means of the user's finger it reverts to its normal (unset) condition, means being provided to memorize or store the position to which the control was set.

Abstract: A process for the dehydrohalogenation of a 7-halo- or a 1,7-dihalodihydrocodeinone dialkyl ketal of the general formula (I): ##STR1## in which R represents an alkyl group containing from 1 to 6 carbon atoms, X represents hydrogen or chlorine or bromine and Y represents chlorine or bromine which comprises subjecting the ketal to the action of a base in the presence of a polar aprotic solvent. The process has utility in facilitating the production of codeine.
