Abstract: Techniques are described for monitoring and determining the influence of a donor on a target organization using blockchain technology. In an example embodiment, a system, comprises a memory that stores computer executable components; and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise: a communication component that receives donor information over a period of time and a recording component that records the donor information in a blockchain stored on a blockchain network as the donor information is received over the period of time.

Abstract: Polyolefins, especially polypropylene, can be made flame retardant by the incorporation therein of a synergistic mixture of a selected hindered amine substituted by an alkoxy, cycloalkoxy or hydroxyalkoxy moiety and a selected organic or inorganic brominated and/or phosphorus containing flame retardant, such as ammonium polyphosphate or decabromodiphenyl oxide wherein the amount of organic or inorganic flame retardant required to achieve an acceptable level of flame retardancy is significantly reduced compared to that needed when the hindered amine is not present.

Abstract: Hindered amine compounds containing a group of the formula where G1 and G2 are independently alkyl of 1 to 4 carbon atoms or are together pentamethylene, Z1 and Z2 are each methyl, or Z1 and Z2 together form a linking moiety which may additionally be substituted by an ester, ether, amide, amino, carboxy or urethane group, and E is alkoxy, cycloalkoxy, aralkoxy, aryloxy, —O—CO—OZ3, —O—Si(Z4)3, —O—PO(OZ5)2 or —O—CH2—OZ6 where Z3, Z4, Z5 and Z6 are selected from the group consisting of hydrogen, an aliphatic, araliphatic and aromatic moiety, when added to a wide variety of polymeric substrates, particularly polyolefins and styrenic polymers, surprisingly bestow flame retardant properties to such compositions.

Abstract: A moisture barrier bag for containing semiconductor wafers. The bag includes at least one opaque panel made of moisture barrier material, and at least one window panel made of at least partially transparent material. The window panel is joined in sealing relation to the opaque panel. The opaque panel and window panel are capable of defining a volume for receiving semiconductor wafers therein. The window panel permits optical inspection of semiconductor wafers received within the volume. The moisture barrier material has a moisture transmission rate which is sufficiently small to permit storage of semiconductor wafers within the volume for an extended period of time without damaging the wafers by moisture attack.

Abstract: A three-part valve means is used in an electromagnetic fuel injector to control fuel flow out through a metering orifice, defined by the valve means in an open position relative to an associated valve seat, to an injector discharge orifice located closely downstream of the metering orifice. The three-part valve means includes a valve member provided with a flat surface on one end thereof and a semi-spherical seating surface at its opposite end for seating engagement with the valve seat; a movable armature having a flat at one end thereof for abutment against the flat surface of the valve member; and, a valve retainer operatively connected to the armature for supporting the valve member with its flat surface in abutment against the flat of the armature for movement therewith, the valve retainer permitting the flat surface of the valve member to move transversely relative to the flat of the armature.

Abstract: An electromagnetic fuel injector has a guide pin for axial alignment of a movable armature. The guide pin is provided with an abutment shoulder thereon for engagement with a surface of the armature whereby to serve as an abutment so as to establish a predetermined minimum working air gap between the opposed surfaces of the armature and the pole piece of the associated solenoid coil.

Abstract: In an electromagnetic fuel injector at least one and preferably the physically softer one of the opposed working air gap surface of the pole piece and armature of the injector solenoid assembly has a roughened surface texture thereon with an average surface roughness rating value of the order of 16 to 32 microinches.
