Abstract: An automatically guided vehicle that runs guided by guide signals transmitted from guiding material laid on the floor. The wheels at the four corners of the chassis of the vehicle are casters that can be switched over between free and fixed modes. A steering drive unit which can move by itself in longitudinal direction is mounted on the lower surface of the chassis at approximately the center thereof. Sensors that detect guide signals are provided at the front and rear parts of the steering drive unit. The steering drive unit changes its operating position automatically as the vehicle switches over between forward and backward running modes. The casters change modes in such a manner that, as the automatically guided vehicle switches over between forward and backward running modes, the casters at the front function as free wheels while the casters at the rear function as fixed or pivot-restrained wheels.

Title: Improved system for routing packet switched traffic
Inventor: HAN YIH-WU
IPC: H04Q3/00
Filed: 1998-03-10
Granted: 2002-11-19
Abstract: The system of the invention uses ATM switches as high performance Internet routers by using standard ATM signaling to set up cut-through paths. The cut-through paths are Switched Virtual Paths which are shared with similar flows toward the same destination and a similar Quality of Service (QOS). The concurrency of multiple flows is achieved by using a different Virtual Channel Identification (VCI) for each flow. The cut-through paths are reused to minimize the overhead associated with setting up and tearing down the paths. Depending on the needs of the traffic, different SVCs having different QOS and different bandwidths can be used. Customer service needs and traffic measurements data are used to identify potential cut-through paths. Once a cut-through path is set up, IP mechanisms are used to update the routing tables of related routers and ATM hosts. Specifically, IP protocols' adjacency bring-up procedures and reachability exchanges are used to update routers' routing tables, and ICMP redirect messages are used to update ATM hosts' routingtables. All ATM QOS are available for the cut-through paths.

Abstract: A method is provided for reducing emissions of harmful nitrogen compounds from a pulp mill (e.g. kraft mill) having malodorous gases which include ammonia and reduced sulphur compounds therein. The method is practiced by (a) treating the pulp mill malodorous gases to lower the ammonia content thereof (e. g. by washing them with a bisulfite solution, such as one produced from washing flue gases with sodium sulphite), and then (b) burning the malodorous gases (e. g. in a dedicated incinerator, recovery boiler, power boiler, or lime kiln) under conditions which effect oxidation of reduced sulfur compounds therein (e. g. with an air excess of at least about 3% and a temperature of over 800 degrees C) so as to reduce odor emissions and emissions of harmful nitrogen compounds from the pulp mill. In the method (a) and (b) may be practiced using malodorous gas from a steam stripper as part of the malodorous gases treated, and the operating conditions, including the pH, of the stream stripper may be regulated in order to reduce the ammonia content of the clean condensate it produces.

Title: A system for ocular ultramicrosurgery
Inventor: YU DAO-YI
IPC: A61B34/00
Filed: 1997-04-17
Granted: 2011-07-05
Abstract: A system (10) for ocular ultramicrosurgery includes a ring (12) for immobilising eye (14) of a patient. The incision point (P) on the eye (14) for surgical tools is marked by a marker (16) that is generated by intersecting the beams of lasers (104 and 106). The intersection point of the laser beams is fixed in space. In order to move the patient's eye (14) so that point (P) coincides with that fixed point in space, the patient's head (52) is fixed to a head positioner (24). The head positioner is operated by a surgeon (26) through joystick (34) and computer (32) to ensure registration of point (P) and the point designated by the intersecting laser beams. All surgical tools used in the system (10) are supported, positioned and operated or worked by a tool support and positioning system (18). The system (18) comprises a stereotactic manipulator (20) and a tool translation table (22) which is supported on the manipulator (20). The manipulator (20) is used to position a surgical tool (50) on table (22) so that tip (51) of the tool (50) can be aligned with point (P). Thereafter, the manipulator (20) and/or table (22) can separately or in combination be used to pivot the tool (50) about point (P) so that the tip (51) of the tool is positioned at any desired location within the eye and subsequently worked or operated to perform ultramicrosurgery. Surgeon (26) is able to control the manipulator (20) and table (22) via computer (32) and input devices such as joysticks (34, 35) and keyboard (36). In this way, the surgeon's hands are isolated from the movement of the tool (50).

Abstract: Plain oval cigarettes which issue from a maker in such orientation that the minor axes of their oval cross-sectional outlines extend vertically are advanced lengthwise in the spiral groove of a trough toward an outlet where the major axes of their oval cross--sectional outlines extend vertically. The thus reoriented oval cigarettes are attracted to the undersides of receptacles which are pivotably mounted on a rotary carrier and deliver the cigarettes, without any further changes in the orientation of the major and minor axes of their cross-sectional outlines, to successive peripheral flutes of a rotary drum-shaped conveyor which transports the cigarettes in such a way that the minor axes of their oval cross-sectional out-lines extend radially of the rotational axis of the drum-shaped conveyor. This ensures that the oval cigarettes are more reliably held in their flutes during advancement with the drum-shaped conveyor.

Granted: 2004-05-04
Abstract: A gaseous-fueled reciprocating internal combustion engine includes a carburetor having a throttle valve that is controlled by a speed governor. A proportional fuel control valve is disposed intermediate a fuel supply and the carburetor, and is controlled by an air fuel computing device. The computing device generates a control signal to adjust the fuel control valve based on a governor sensed variable indicative of engine speed, sensed engine torque, a governor output signal from the governor indicative of an opening position of the throttle valve wherein 100% corresponds to a wide open throttle position, and 0% corresponds to a closed position, and a lean combustion control map containing predetermined set point values stored in memory. During operation, the control valve is responsive to the control signal generated by the computing device for adjustment of a fuel flow therethrough so as to obtain a ratio of air to fuel provided to the engine that is substantially at a lean misfire limit of the engine, thereby reducing fuel consumption, NO x emissions, and reducing exhaust gas temperatures.      Alternatively, the control signal is generated using engine speed alone.
