Title: System and method for teleconferencing on an internetwork comprising connection-oriented and connectionless networks
Inventor: REIT ROBERT E
IPC: H04M11/00
Filed: 1998-01-22
Granted: 2001-04-03
Abstract: A system and method for teleconferencing between conferees connected through a connectionless network and conferees connected through a connection-oriented network having a bridge. A call server connects to a bridge hosting a teleconference among connection-oriented conferees and joins the teleconference.The connection-oriented signal received by the call server is converted into a connectionless signal and sent to authorized, authenticated conferees connected through the connectionless network. The call server receives a connectionless signal from a conferee through the connectionless network, converts the signals to a connection-oriented signal and sends the connection-oriented signal to the bridge. Connectionless signals are stored in a database to be analyzed or sent to other conferees, such as those who were unavailable to join the teleconference as it occurred. The call server provides multimedia interfaces to conferee by which the conferees can monitor and join an ongoing teleconference, access a stored teleconference, or configure a new teleconference. The call server can also bridge teleconferences hosted on two or more bridges, expanding the audience for a given teleconference beyond the capacity of a single bridge.

Title: Reconfigurable meter roller and blank section
Inventor: GREGOR DAVID WALTER
IPC: A01C7/12
Filed: 1998-08-04
Granted: 2002-12-17
Abstract: A meter roller is provided with a blank section for enabling an air seeder to achieve a substantially uniform seed rate throughout the width of the tillage. The fluted meter roller has a series of ridges spaced around its periphery, between which are located product receiving valleys. The blank section conforms to the fluted cross-section of the meter roller by projecting into the product receiving valleys of the meter roller. When a series of meter rollers is driven by a common shaft, the output of an individual meter roller may be modified by adjusting the number or size of blank sections attached to the meter roller.

Abstract: A slider (36) has a base fixture (40) and a shielding tube (42). The slider (36) is used to operably couple a detonator (44) to a detonating cord (62) that passes through a booster device (10), i.e., to prevent the detonating cord (62) from directly initiating or fracturing the booster (10). The base fixture (40) includes input lead-retaining means for disposing the input lead (47) of a detonator (44) in signal transfer relation to the detonating cord (62). Optionally, the slider (36) has a detonator retainer (38) for carrying the detonator (44) on the slider (36). Preferably, the detonator retainer (38) is able to hold detonators of various lengths in proper position to initiate the booster device (10). By disposing the shielding tube (42) on the slider (36), a booster device (10) can be used with various detonating cords (62), and a slider (36) having a shielding tube (42) suitable for the chosen detonating cord (62) can be inserted into the booster device (10).

Abstract: A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system.  The electric submergible pumping system and the conduit are inserted into the wellbore, and the electric cable is permitted to buckle in a manner so that the electric cable buckles and contacts an interior surface of the conduit at a plurality of locations to prevent longitudinal movement of the electric cable within the conduit. Since the cable is self supported within the conduit, there is no need for cable anchors or other devices to transfer the weight of the cable to the conduit.

Abstract: An electric induction motor can be given a kick start without excessive current drain on the supply by first connecting a unidirectional supply to a winding of the motor to build up a stationary rotor flux and the n applying a starting current to another winding of the motor to produce a stator flux at an appropriate angle (between 0.degree. and 180.degree.) with the stationary rotor flux. Once the motor has begun accelerating the normal running supply can be connected. This starting current may be derived from a capacitance which is charged up during the period of establishing the stationary rotor flux.

Abstract: This invention provides a method and apparatus for mixing calcined gypsum. The invention comprises a mixer which employs high pressure water to eliminate or substantially reduce the formation of lumps of gypsum inside the mixer which cause paper breaks when the calcined gypsum slurry containing the lumps is used to form the gypsum core in a gypsum wallboard product. High pressure water jets direct a spray of high pressure water at the surfaces within the mixer where the lumps of gypsum are formed. The method of this invention utilizes the high pressure water as part of the metered water that is continuously fed to the mixer, with the balance of the water being fed through low pressure nozzles.

Abstract: A helicopter-type craft is disclosed which obviates the need for the main rotor blades to be variable in pitch to maintain control and provide vertical lift.      The aircraft has a main rotor (1) and engine (2) at the top of the aircraft which can be tilted as a unit in a plurality of directions and angles with respect to the body of the crafts. Tilting occurs at a universal joint (3) which may be fixed in position (as depicted) or alternatively mounted on top of a telescoping tower so as to vary the height of the centre of tilt with respect to the body of the craft. Tilting may be effected by handles (4, 5) or alternatively be powered using hydraulic or pneumatic linear actuators. Stability of the craft is maintained by tail rotor (10) powered by a separate engine (11) and possibly by pitch-controllable fins attached to the body of the craft.

Abstract: A skid plate for a concrete saw has opposing ends connected by a truss, with mounting fixtures that connect opposing ends of a skid plate to the concrete saw. The mounting portions are connected to an apparatus that simulates the saw's mounting structure, and that simulates the load distribution the saw exerts on the skid plate in use.      Sensors detect the force or deflection at various locations on the skid plate that occurs from the simulated load. One end of the truss and skid plate are moved relative to each other to ajust the sensor readings on the skid plate to achieve a predetermined profile that reduces raveling of a concrete surface during cutting.

Abstract: IP packet transmission equipment in a network containing backbone and branch transmission lines and transmits optical path signals between two nodes via logically defined optical paths. Wavelength demultiplexing means demultiplexes a wavelength-multiplexed signal from each backbone transmission line to form optical path signals. IP packet routing means converts a transmission signal from each branch transmission line to IP packets for outputting the destination corresponding to routes. IP/optical path converting means converts the IP packets to optical path signals. Optical path switching means cross-connects optical path signals from the wavelength demultiplexing means and the IP/optical path converting means to destination output routes. Optical path multiplexing means wavelength multiplexes optical path signals on predetermined routes to generate an output wavelength-multiplexed signal which is output to each backbone transmission line. Optical path signals contain an optical path payload for storing the IP packet to generate a payload signal.

Abstract: A two-piece hub extension for adding dual wheels to a mechanical front-wheel drive axle of an agricultural tractor has an inner extension ring that surrounds the final drive cover of the front axle and an outer extension member of reduced diameter that extends outward from the inner extension ring. The inner extension ring only extends outward far enough to clear the axle final drive cover. The inner ring is mounted by bolts that extend entirely through ring so that the bolt heads are external of the inner ring and can be easily reached. The outer extension member is mounted to the inner extension ring by long bolts extending through the inner extension ring and into the hub. The dual wheel is mounted to the outer wheel hub.    The reduced diameter of the outer extension member results in improved crop clearance between the two tires.
