摘要:
A tactical illuminating system for weapons. The tactical illuminating system for weapons has a grip body with a joystick button. The grip body has at least first and second illumination sources and at least one laser emitter. The grip body mounts onto a rail member of a quail rail hand guard. The tactical illuminating system also has an electrical system and at least first and second side illuminator housings with third and fourth illumination sources respectively. The at least first and second side illuminator housings mount onto the quail rail hand guard. The at least first and second, and third and fourth, illumination sources are positioned on both sides of a weapon, and are independently controlled by the joystick button to provide light sources on strong and/or advantageous sides of the weapon when cornering without having to change grip, sight picture, an angle of said weapon, or stance.

摘要:
The present invention comprises a process of mixing a luminous substance in powder form to a transferable grade molding compound in a pelletized or powder form, such as a clear epoxy, to derive a homogeneous mixture that can be pressed and sintered into solid pellets. The solid pellets are further processed so as to permit their deposition on and around a light emitting semiconductor driver so as to obtain a white light emitting semiconductor device. This white light emitting device can be used in a variety of lighting applications.
摘要:
System and method is provided for adding addressing information to an indicium printed by a closed system metering device. A scanning device is coupled to a closed system postage meter for scanning addressing information printed on a mailpiece. The addressing information is combined with other information relating to the postage payment for the mailpiece to obtain postal data relating to the mailpiece. The postal data, including the addressing information is used to generate an indicium for the mailpiece. The indicium includes cryptographic evidencing of postage payment. The closed system metering device prints the indicium on the mailpiece.

Temporary wet strength resins, more particularly, temporary wet strength resins comprising a polymer backbone, wherein the polymer backbone comprises a co-crosslinking monomeric unit, preferably a reversible co-crosslinking monomeric unit, especially in the presence of water, a homo-crosslinking monomeric units and a cationic monomeric unit, fibrous structures comprising such temporary wet strength resins, sanitary tissue products comprising such fibrous structures and processes for making such fibrous structures and/or such sanitary tissue product. Such fibrous structures and sanitary tissue products exhibit high initial wet tensile strength and improved flushability properties.

A compound of formula (I): where R1 is alkyl or alkenyl, Y1 and Y2 are independently selected from oxygen or sulphur, n is an integer of from 1 to 5, A is an optionally substituted phenyl or an optionally substituted cycloalkyl ring, X is a direct bond, a C1-4alkylene, a C2-4alkenylene, an acetylene, —CO(O)— or a group of sub-formula (i): where X1 and X2 are independently selected from a direct bond, a C1-4alkylene, a C2-4alkenylene, an acetylene, —CO(O)— and R2, R3 and R4 are independently selected from hydrogen, halo or cyano, provided that no more than one of R2, R3 and R4 is hydrogen. These compounds have a high dipole moment and may be used as dopants in liquid crystal mixtures.
摘要:
System and method are provided for selecting and accounting for value-added services with a closed system metering device. A scanning device coupled to the closed system postage meter scans information, including recipient address, printed on a mailpiece. From the scanned information or manual selection, a selection of value-added services is made and the closed system metering device performs accounting related to the selected value-added services. The recipient address is combined with other information relating to postage payment for the mailpiece to obtain postal data relating to the mailpiece. The postal data is used to generate an indicium, which includes cryptographic evidencing of postage payment. A graphical representation of the selected value-added services is added to the generated indicium to generate a value-added indicium, which is then printed on the mailpiece.
