Abstract: A trimmer that is operable to cut at least one sheet of paper includes a base configured to support the at least one sheet, a rail extending across at least a portion of the base, and a cutting assembly having a carriage slidably coupled to the rail and a blade positioned on the carriage. The trimmer also includes a blade opposing member coupled to the base adjacent to the rail and an indicator operable to display a usable life status of at least one of the blade and the blade opposing member.

Abstract: A system for dispensing adhesive onto a surface is provided. This system includes a dispenser and a quantity of discrete units of adhesive releasably deposited on a substrate. The dispenser includes a drive mechanism that further includes an actuator for actuating the dispenser; and a drive wheel, wherein the drive wheel further includes mechanical means for engaging the actuator. An optional supply wheel may be included in the dispenser. The quantity of discrete units of adhesive is releasably deposited on a substrate that may be mounted on the supply wheel or that may simply sit within the dispenser. The substrate further includes means for cooperating with the drive wheel to incrementally advance the substrate a substantially fixed, and predetermined distance upon actuation of the dispenser.

Abstract: A cutting system that includes a rotary blade cartridge that can be interchangeably used with a variety of cutting tools is disclosed. The cartridge houses a rotary blade assembly that is maintained in a secure and safe retracted state and that can be activated when the cartridge is inserted into a cutting tool. Activating a plunger of any of the cutting tools causes a piston of the rotary blade assembly to move the blade to an operative cutting position protruding from an aperture provided in the cartridge housing. Deactivating the plunger causes the blade to be return to its retracted and inoperative position within the housing. Cutting tools of the invention include rail cutters such as a primary workstation and a compact workstation, circle cutters, elliptical cutters, and freeform cutters. Each cutting tool is capable of receiving a rotary blade cartridge. Cartridges are freely interchangeable between the cutting tools.

Abstract: A fluid supply monitoring system includes a housing, a shutoff valve and a flow sensor positioned downstream from the shutoff valve within the housing. The shutoff valve selectively blocks a fluid flow. The flow sensor is operable to monitor the fluid flow to calculate at least a length of time the fluid flow has flown without interruption, a total volume of the fluid flow that has flown, and a flow rate of the fluid flow.

Abstract: A method for testing a fluid supply system includes periodically preventing a fluid flow through the fluid supply system, and measuring a system pressure of the fluid flow subsequent to the step of preventing the fluid flow.

Abstract: A device for sharpening crayons, wax pencils, and the like is provided. This device includes: a multi-blade removable and replaceable crayon sharpening cartridge; an electric motor mechanically coupled to the blade cartridge for axially rotating the blade cartridge around a crayon that has been inserted into the blade cartridge; a base for supporting the electric motor; a contoured receptacle positionable on the base beneath the blade cartridge for capturing crayon debris; and a contoured exterior housing for enclosing the electric motor and the blade cartridge.

Abstract: A miniature hand-held stapler is provided. This stapler includes a body for holding staples and providing a stapling mechanism, a lid attached to the body by hinge means, a base attached to the body and to the lid, wherein the base further includes a first portion and a second portion detachably or fixedly attached to the first portion, and wherein the second portion further includes a flexible or resilient band attached thereto or formed integrally therewith, and wherein the flexible or resilient band may be deployed over a portion of the lid to secure the lid and the body to the base when the stapler is being stored or transported.

Abstract: A device for dispensing staples is provided. The device includes a body for holding at least one staple, a lid attached to the body by hinge means, wherein a top surface of the lid further includes a substantially planar surface, a base attached to the body by hinge means, and an actuating lever attached to the base by hinge means, wherein a portion of the actuating lever contacts the substantially planar surface on the lid when the actuating lever is depressed.

Abstract: Cutting apparatus and methods are provided for cutting and trimming of flat materials, the invention incorporating an optical guide means for positioning of the flat material in a desired orientation. A laser device is positioned on a cutter to project a visual indication of the line of cut to be made by the cutting blade, and optionally along other lines such as to show a border or margin. Means are provided to power the laser device, and an optical element is provided to focus an emitted beam onto the cutter base, and any material placed thereon. Additionally the cutter includes a switching means for turning the laser device on and off. The switch can be mounted anywhere on the base or the cutting assembly. The cutter includes a cutting base for supporting the materials to be cut, a cutting blade assembly, and assistive cutting means such as a bottom blade on one edge of the base or a pad cooperating with the cutting blade to cut the flat material.
