Abstract: A sanitizing system for sanitizing currency bills at a retailer has a sanitizing apparatus that has an inlet for the insertion therethrough currency bills by a customer, the sanitizing apparatus including a reader for reading the currency bills to establish the total monetary value thereof, and for issuing a receipt to the customer reflecting the total monetary value. A reader located adjacent a cash register at the retailer reads the receipt and accepts the total monetary value as cash tender for merchandize being purchased. A counterfeit detector tests the currency bills and rejects currency bills that do not meet predetermined genuine criteria.

Abstract: A sanitizing apparatus for sanitizing sheets, typically currency bills, has a housing defining a sanitizing chamber with an inlet and an outlet for the ingress and egress, respectively, of the currency bills. An intake conveyor conveys the currency bills into the sanitizing chamber into the sanitizing chamber and an outlet conveyor is arranged in the sanitizing chamber along a conveying direction and spaced away from the intake conveyor across a gap therebetween. An upper ultra-violet (UV) lamp is located above the gap and a lower UV light is arranged below the gap. An electrical system causes the upper UV lamp and the lower UV lamp to direct UV light onto an upper surface and a lower surface of the currency bills they are conveyed into the sanitizing chamber and travel across the gap, the UV light being selected to have an intensity to sanitize the currency bills as they pass through the sanitizing apparatus.

Abstract: A stacked marker is formed by stacking individual stackable markers where each stackable marker is a fully functional marker and each stackable marker can be selected for use and then reassembled to store the restackable marker. Each stackable marker is originally assembled as an otherwise ordinary marker, but with a temporary utility cap, which, upon being inserted into a rear receptacle in another marker, is left therein to form the permanent cap for other markers. When fully assembled, the stacked marker becomes a multi-unit final assembly that affords one the use of a plurality of different types of markers that are snapped together during non-use and taken apart to select individual markers during use.

Abstract: An ink composition or system for writing instruments constructed with a polyester fiber reservoir and a porous oriented fiber nib. This ink system will write on both black and white surfaces. On black surfaces, it will reveal itself as being opaque and metallic almost iridescent in appearance. On white surfaces, a tint of color is observed with distinct flecks of silver. The ink system is composted of water as a carrier, a permanent water-based binder, a colored pigmented permanent water-based dispersion of sub-micron particle size, a unique aluminum dispersion of specific particle size in a special carrier, a humectant, a surfactant that lowers surface tension, an anti-settling additive, a preservative and a base acting as a pH adjuster.

Abstract: An air flow measurement device includes a connector conduit with a constant inner diameter wall for the air flow, a transverse restrictor plate located within the conduit with a plurality of generally uniformly spaced apertures extending therethrough, and an annular mounting piece secured centrally about the conduit for securely mounting a pair of air pipes to the opposite ends of the conduit in air-tight engagement therewith. The restrictor plate is maintained in the connector conduit by a swaging operation which causes it to be expanded outwardly into tight engagement with the conduit wall. A pair of tank valves are mounted, by a special saddle, to the mounting piece, and passages are provided through the mounting piece and conduit wall for communication with the interior of the conduit just upstream and downstream of the restrictor plate whereby a differential pressure meter may be connected to the valves to measure the difference in pressure to thereby determine the air flow rate.

Abstract: An optical fiber sensor for inducing a microbend in an optical fiber in the presence of the liquid phase as distinguished from the vapor phase of a fluid such as water. The sensor includes a chamber with an expansible block located therein, and a thin band is provided about the block of a dimension and tensile strength such that any increase in outward expansive force in the block due to an increase in the presence of the fluid in its vapor phase only will not cause the band to rupture; however, when any liquid enters the chamber, the band will rupture to allow the block to expand in a particular direction to move a pusher bar which, in turn, moves a puller wire to bend the fiber at a location remote from the chamber.

Abstract: A rigid cylinder is provided with small perforations to permit the entry of hydrocarbon containing liquids, gases or vapors, and the interior of the cylinder is lined with a sensor material which expands in the presence of hydrocarbons. The interior chamber enclosed by the sensor material is completely filled with an incompressible liquid, and one end of the chamber is sealed by a conventional pressure sensor so that the presence of hydrocarbons causes the sensor material to exert a pressure upon the incompressible liquid to create an output signal in the pressure sensor. A double-chambered device, with only one chamber being perforated and thereby exposed to the hydrocarbons, can be used to compensate the pressure sensor signal for ambient pressure or temperature changes.

Abstract: An optical fiber sensor for inducing a microbend in an optical fiber in the presence of a detectable fluid such as water includes a chamber with an expansible block located therein. When water enters the chamber, the block expands in a particular direction to move a pusher bar which, in turn, moves a puller wire to bend the fiber at a location remote from the chamber. A gap may initially be provided between the expansible block and the pusher bar so that the presence of water vapor within the chamber will not move the pusher bar but the presence of liquid water will.

Abstract: A barrel shaped holder defines a fluid reservoir and is provided with an applicator at its front and a plug at its rear end. A valve independent of the applicator is interposed between the reservoir and the applicator, and is arranged to be in normally closed condition and opened by an actuator which extends through the reservoir in abutment with both the valve and the plug. The plug is flexible and resiient so that manipulation of the plug operates the actuating rod and the valve.

Abstract: A cable is disclosed having two optical fibers spaced apart by portions of two strands of fibrous material laid with the optical fibers that is made by laying the two optical fibers and two strands of fibers with the serve angle of the strands of fibrous material being less than the serve angle of the optical fibers and at 90.degree. thereto to cause the optical fibers to be held apart by portions of the fibers making up the strands. Tape is wrapped around the twisted optical fibers and strands of fibrous material after which the laid optical fibers and the fiber strands are enclosed in an outer jacket.
