摘要:
This invention relates to the packaging and subsequent removal of dry marking materials that tend to clump or bridge when shipped or stored in containers. Human operators are presently instructed to agitate such containers before installation into a marking engine but such agitation is unreliable. The present invention involves placement of agitation vanes on a displaceable inner seal within the cartridge such that such vanes will break apart clumps and bridges of the marking material during installation of the container upon the marking engine.

A stalled sheet folding and flattening apparatus for reducing a sheet, stalled between a withdrawable and a fixed component of a cut sheet handling system of a sheet handling machine, into a shape and size suitably enabling reliable removal of the stalled sheet through even a relatively narrow gap between the withdrawable and fixed components of the sheet handling system. The stalled sheet folding and flattening apparatus includes a fixed component of the sheet handling system connected to a frame of the machine and having a first section of a sheet path; a withdrawable component of the sheet handling system mounted to the frame, and having a sheet flattening side defining a relatively narrow gap between a fixed surface within the machine and the withdrawable component, and including a second section of the sheet path adjoining the first section of the sheet path; and a sheet folding device mounted to the fixed component. The sheet folding device includes a generally U-shaped portion defining a slot and having a sheet contact surface forming a part, of an edge of the first section of the sheet path, for contacting and deflecting into a first fold, an edge of a sheet stalled across an interface between the first and the second sections of the sheet path, when the withdrawable component is being pulled out of the machine. The sheet contact surface of the U-shaped portion has a first radius of curvature defining a first concave surface for deflecting and folding the stalled sheet, and a second radius of curvature defining a second surface for guiding the folded sheet out of the slot.

A more intuitive and easier to use repositionable sheet stack edge guide, in which a single simple manual movement of a single visible upstanding member in either of the opposite possible repositioning directions can both automatically unlatch the edge guide latching system from its previously latched position by the partial pivoting of that member and also move the edge guide in its desired repositioning direction.

A reduced footprint image producing machine including (a) an image output terminal (IOT) having (i) a moveable imaging member including an imaging surface; (ii) latent imaging devices for forming a latent electrostatic toner image on the imaging surface; (iii) a development unit for developing the latent electrostatic image on the imaging surface into a toner image; (iv) a transfer station for transferring the toner image from the imaging surface onto a toner image carrying sheet; (v) a fusing apparatus for heating and fusing the transferred image onto the toner image carrying sheet; and (b) a footprint-reducing tower mounted on top of the IOT and containing (i) machine electronics and controller assembly, and (ii) machine environment conditioning devices including cleaning and exhaust fans along with portions of associated manifolds, thereby preventing the addition of protrusions to a rear of the IOT, and thus reducing the installed foot print of the machine.

An enlarged buckle chamber is positioned within an easily accessible, copy sheet transport path and used to compile sheets during fault cycle down in copiers/printers whenever sheets are prevented from reaching the output in sequence by jammed sheets. The user can then clear most jams by accessing the jam area plus the "easy to reach" area where internally purged sheet are gathered, thereby avoiding having paper distributed all over the paper path.

An overlay for use with a display screen, comprising at least one first tactilely readable area, wherein the display screen includes a first feature thereon, wherein the tactilely readable area includes information in a tactilely readable format, and wherein the information identifies a first feature displayed on the screen.
摘要:
A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device comprises an open ended container defining a chamber in communication with the open end thereof. The particles are stored in the chamber of the container. The device further comprises a puncturable seal attached to the open end of the container for sealing the chamber. The container is installable into the developer unit without removal of the seal.
摘要:
A walled enclosure or cage is provided in which laboratory animals may be maintained for observation and evaluation. The floor of the enclosure is provided by a plurality of conductive bar elements that are spacially separate and extend across the bottom of the enclosure. Spacial separation of the bars insulates one from the other and further, space is provided in the floor to remove animal waste, excess food and the like. An electrical resistor is connected between each two adjacent conductive bars and cooperate with the bars to define a resistor network to which a closely controlled feed current is supplied. An animal makes contact with the conductive bars which lowers resistance of the network and produces a voltage change. The resistor network is a.c. coupled to a differential amplifier, and a comparator which receive pulses from capacitors between the network and the amplifier and prepare same for an interface means for a pulse recording system. The amplified pulse may be shaped, divided or the like as required by the recording system. The method of using the present system involves detection of contact between an animal foot and the conductive grid bars, whereupon contact area determines the resistance of the network and a proportional signal is produced therefrom. The signal is then amplified, manipulated to avoid ambient electrical interference, such as an incidental electrical field from line current at 60 Hertz, and/or shaped, divided or the like to provide input to a particular recording system. Raw data from the recording system can then be correlated to locomotor activity of the laboratory animal.
