Abstract: A compact sheet feeding and cutting apparatus is disclosed which is particularly suitable for retrofitting to an existing document reproduction machine. The sheet feeding and cutting components are located within a common housing which can be mechanically attached to an existing machine. In one embodiment, no electrical connections are required between the reproduction machine and the feeding and cutting apparatus. A sheet cutting length is entered into local memory and controls the operation of a dc stepper motor in a sheet cutting mode and a sheet feeding mode. The motor is reversed and operates in a sheet feeding mode to drive feed rollers causing the sheet to unroll from a supply roll. The motor is operatively connected to the drive feed rollers and to the sheet cutter through separate, one-way clutches. The sheet is fed from the roll at a faster speed than the speed of sheet travel within the reproduction machine as it advances to a transfer station.

Abstract: Method for absorbing, removing, and for cleaning up a first liquid floating on or in a second liquid, the method employing absorbent pellets which, in preferred embodiments, have a particular size, density, and configuration. The method can include steps of introducing the pellets onto or into the floating liquid to be removed; in preferred embodiments additional steps of agitation and spraying or applying a surfactant can be employed. The pellets containing the liquid to be removed can be removed from the surface of the second liquid; from an intermediate location above the lowermost depth of the liquid; or from the bottom level of the liquid or the bottom of the container or reservoir holding the liquid. A method for making pellets for cleaning up a first liquid floating on or in a second liquid; and a method for making pellets for absorbing a combustible material to produce fuel pellets. A method for producing fuel pellets.

Abstract: A toner cartridge is modified by the addition of a low toner sensing mechanism internal to the cartridge. An arm is pivotably mounted within the cartridge; the suspended end of the arm having a magnet secured thereto. When the cartridge is filled to a relatively high level with toner and rotated, the suspended arm is at least partially submerged in the toner bed and is subjected to a viscous drag force which moves the arm from the vertical position and prevents the arm from returning to the vertical or plumb orientation until a sufficiently low toner level occurs. At this point the arm is sufficiently free from the viscous drag effects of the rotating toner bed and attains a plumb position which brings it into alignment with a switching circuit which is closed by action of the proximate magnet. The switching circuitry generates signals which are used to produce a visible or audible signal to the operator, and/or which cause machine shut down to occur.

Abstract: A copying system with a large document feeder for making large copy sheet (or web) media copies by moving the document past an optical scanning slit at a preset speed proportional to the speed of the imaging surface, and transferring the image onto a selected large copy media, with an easily correctable image size. The disclosed system provides for accurately controlling and adjusting the size of the copy image relative to the document image, by controlled adjustment of the magnification or reduction without requiring anamorphic or other lens changes.

Abstract: A fusing system incorporates a thin fabric-like web to maintain copy sheets in biased contact with a fuser roll during a fusing operation. The copy sheets are introduced to the fusing area at an entrance nip formed by a blade member biased tangentially against the fuser roll. The copy sheets are fed into frictional engagement at this entrance nip, reducing the tending of the copy sheets to stall or buckle.

Abstract: Heat and pressure fuser for fixing toner images to copy substrates wherein a heated roll or roller contacts the toner images on the copy substrates and a non-rotating, elongated pressure member cooperates with the roll or roller to form an elongated nip. The heated roll is fabricated such that it constitutes a low mass member. The fuser of the present invention is relatively low in cost, simple in construction, occupies less space in the machine than prior art devices and has a fuser roll which has a relatively low mass.A pressure member in the form of a sling or web is urged into pressure contact with the surface of the fuser roll. One of the ends of the web or sling is captivated in a machine structure while the other end is biased into pressure engagement with the fuser roll. A portion of the sling closer to the captivated end thereof is also biased into engagement with the fuser roll.

Abstract: An apparatus which includes a plurality of heating elements to fuse a powder image onto a copy sheet. Selected heating elements of the apparatus are energized in an ordered sequence corresponding to the surface area of the powder image being fused.

Abstract: A fiber adhesive is provided which is a mixture of sodium silicate and an acrylic resin, as well as a method for preparing the adhesive and spraying a mixture of the adhesive and the fiber.

Abstract: An arrangement is disclosed for combining the capability for bound document copying with a document handling apparatus in a reproduction machine. To this end, an arrangement is devised wherein the document handling apparatus is contained within a frame which contains a light-tight cover for bound documents having three-dimensional shape. The arrangement includes a pivoting connection between the document handling apparatus and the frame relative to the platen of the reproduction machine and between each other so as to permit access to the platen for manual document placement and bound document copying.

Abstract: A sheet feeding device (10) that feeds sheets individually from a stack (31) includes a sheet feeding member (20) that strikes the stack (31) at such an acute angle .theta. and normal force that the top sheet in the stack is forwarded for subsequent transport while simultaneously retarding movement of the sheet immediately adjacent to the top sheet.

Abstract: There has been provided a television tube having funnel, panel, and neck portions fused together in a conventional manner. A controlled failure zone in the form of a circumferential implosion protection notch is formed in a rearward portion of the funnel for establishing a stress concentration location, such that, in the event of a destructive impact to the panel, the tube will crack along the notch in the controlled failure zone and reduce the implosion potential of the tube.
