Abstract: A two-component development unit for an electrophotographic printer includes a rotatable donor roll having a plurality of longitudinal electrodes along its circumference. A magnetic structure within the donor roll permits two-component developer to be advanced to a development zone. Adjacent electrodes on the donor roll are AC biased to create a powder cloud of toner from the developer in the development zone. The magnetic structure is arranged to provide pole effects substantially immediately downstream and upstream of the development zone in the direction of motion of the donor roll.

Abstract: An accumulation conveyor includes a product sensor that is positioned along the conveyor at a particular zone for sensing the presence of product at that zone and for causing actuation of the zone upstream of that product sensor with respect to product movement along the accumulation conveyor. The product sensor includes an arm that is selectively positioned in the path of product being conveyed, a switch having an actuation member juxtaposed with the arm, and a force-producing member responsive to actuation of the downstream zone actuator in order to apply a force to the switch and, in turn, retract the sensor. This may be accomplished by physically locating the product sensor within the downstream zone and providing an actuator for that downstream zone that is mechanically coupled to the product sensor physically located within that zone. When the actuator is actuated, it retracts the product sensor from the path of movement of product along the accumulation conveyor concurrently with actuation of the downstream zone. The switch may be selectively mounted either to a stationary member or to the downstream actuator. If the switch is mounted to the stationary member, the associated sensing member is not responsive to actuation of the downstream actuator and a non-retractable sensor function is achieved. If the switch is mounted to the actuator, actuation thereof will retract the sensing member from the path of movement of the product along the accumulation conveyor. Thus, each product sensor may be made into either a retractable sensor or a non-retractable sensor. Each actuator includes a moveable member that reciprocates with respect to a stationary support member to which is mounted a signal manifold that interconnects with signal manifolds of adjacent control devices and with a force-producing device for reciprocating the moveable member of that actuator. The accumulation conveyor further includes a drive assembly that is entirely supported by the side rails of the accumulation conveyor in order to thereby be positionable at substantially any longitudinal location along the product conveying surface.

Title: Injection timing and power balancing control for gaseous fuel engines
Inventor: WERTHEIMER HARRY P
IPC: F02D41/00
Filed: 1995-04-25
Granted: 2005-10-18
Abstract: According to the present invention, an apparatus and method for controlling injection timing and power balancing in a gaseous fuel engine with an electronic control unit and a shaft encoder is disclosed. The engine includes an engine block having at least one cylinder with an exhaust port and a cylinder head. A fuel injector and a spark plug is seated in the cylinder head and the injector has a valve which separates the fuel in the injector from the cylinder. A piston reciprocates in each cylinder and is attached to a connecting rod. The rod connects each piston to a crankshaft which converts the motion of the piston to rotary motion. The shaft encoder is connected to the crankshaft and monitors the revolutions of the crankshaft. The electronic control unit is coupled to the shaft encoder and to each of the fuel injectors. The method in accordance with the invention includes several steps. First, a working injection time setting the time for each fuel injector to start an injection of fuel into the cylinder is retarded to an initial injection time. Next, the speed of the crankshaft is measured and compared against a first preset limit. The working injection time is advanced at a predetermined rate, if the monitored speed exceeds the first preset limit. When the working injection time is advanced to be equal to or less than a programed function of speed, the working injection time is set to the injection time calculated from the programmed speed function. The method may also involve establishing a working pulse width for each cylinder, measuring an index of the power output in each cylinder, calculating a balancing factor in response to the measured index, and adjusting the working pulse width in response to the balance factor for each cylinder.

Title: Automatic call back under control of a telephone terminal
Inventor: BALES BRUCE MERRILL
IPC: H04M1/247
Filed: 1995-09-28
Granted: 1999-01-12
Abstract: Telephone terminals directly implement an automatic call back feature by establishing a logical channel between two telephone terminals when a callingtelephone terminal is unable to complete a call to a called telephone terminal. Via the logical link, the called telephone terminal communicates to the calling telephone terminal any change in state that is related to its ability to receive a call. When both telephone terminals are idle, the calling telephone terminal recalls the called telephone terminal to set up a call.  The logical link is established on user-user temporary signaling or D channel facilities of ISDN links. Since the interconnecting networks are not part of providing the automatic call back service, the telephone terminals can be interconnected by any combination of telephone networks that provide ISDN service.
