Abstract: A wheelchair drive system that operatively interposes  a  plural-speed hub subsystem (26) between conventional rotatable hand wheels (18, 20) and their corresponding drive wheel (14, 16), thereby providing wheelchair propulsion by rotary motion of the hand wheels (18, 20) and selective engagement  of the drive wheels (14, 16) dependent upon a manually operated gear-shifting mechanism (22). Preferably, the hub subsystem (26) includes symmetric left-handed  hubs (28) and right-handed hubs (26), each including a hub body fixedly connected with an easily accessible hand wheel, with the hub rotating about a spindle (84) fixedly mounted on the wheelchair and selectively gear-connectable to the drive wheel, the spindle (84) being selectively connected to the drive wheel by the operation of a manually shiftable, plural-speed gear train (Figures 3, 4, 5). The gear train includes plural sets of planetary (72), sun (56) and ring gears (68, 78), formed along an inner surface of the hub, and the planetary gears (72) positioned along a mounted member (62) that is shiftable lengthwise in parallel with the spindle's central axis.  The mounting member (62) is spring-biased (82) against a first side of the hub, with that member being shiftable against spring's tension into alternative positions by a shift rod (34) that extends along a central void formed within the spindle. The shift rod (34) is positionable  by manual operation of a shift bar (24) connected therewith that extends outwardly of the wheelchair to a position of easy access by the wheelchair's user.

Abstract: A burner block for mounting a burner within a furnace containing a melt to be heated by the burner. The burner block comprises a body having a passageway terminating in a divergent opening. The passageway is configured to receive the burner so that the burner is recessed within the divergent opening and a flame produced by the burner is directed out of the divergent opening and over the melt. The divergent opening has a lower section angled in a downward direction and the lower section has a reversed step to produce a primary recirculation zone beneath the flame, thereby to draw the flame in a downward direction toward the melt. The reversed step is positioned within the divergent opening so that when the burner is in use, a secondary recirculation zone forms between the opening and the melt and further draws the flame in the downward direction toward the melt. The height of this secondary recirculation zone will vary with the height of the melt within the furnace to produce a self adjustment of the flame toward the melt. In another aspect, the present invention relates to a furnace incorporating the aforesaid burner block, a burner positioned within the burner block and a melt.

Title: An apparatus and method for credit based management of telecommunication activity
Inventor: JOHNSON ERIC A
IPC: H04M17/00
Filed: 1994-10-19
Granted: 2005-03-22
Abstract: The present invention provides an apparatus for credit based management of a telecommunication system. One embodiment of the apparatus includes an interface (133) for communicating credit information on a particular subscriber and for receiving call records (113) for the particular subscriber that are derived from a switch (111) which establishes connections between telecommunication devices. A credit limit device (131) then utilizes the credit information to establish a credit limit for the subscriber. Another embodiment of the invention provides an apparatus for using a pre-call validation request that is associated with a subscriber of a telecommunication system who is attempting to place calls in an area serviced by another system (i.e., roaming) to detect potentially fraudulent activity and, in particular, cloning fraud. In one embodiment, a detection device is provided that uses a time derived from the pre-call validation request to identify telecommunication activity that occurs in an improbable time sequence and is therefore indicative of potentially fraudulent telecommunication activity.

Abstract: A web winding machine includes two roll beds each formed of two roll support rollers. Each bed receives a respective web roll being wound thereon. The web rolls are at separate locations across the width of the machine. For at least one roll bed, a longitudinally extending packing is introduced from below into the gap between the two support rollers of the bed. A respective movable packing element is at the end of each wound roll and forms a packing gap with the wound roll and with the wall surfaces of the support rollers to enclose a pressure space. A compressed air cushion can be built up below the wound roll in the bed. At least one of the rollers of the roll bed has a perforated roller shell. A stationary pressure chamber inside the shell delivers pressure through the shell into the pressure space. The pressure chamber in the shell can be divided into sections along the axis of the roller. The pressure chamber is adapted to be connected to a source of compressed air. Brackets for supporting each wound roll are disclosed.

Abstract: An apparatus for increasing the transfer rate of production stimulation fluids through a wellhead of a hydrocarbon well is disclosed. The apparatus includes a mandrel for a wellhead isolation tool and a tubing hanger for use in conjunction with the mandrel. The mandrel includes a bottom end to which an annular seal is bonded. The annular seal cooperates with a sealing surface in a top end of the tubing hanger to isolate the wellhead equipment from the high pressures and corrosive and/or abrasive materials pumped into the well during a production stimulation treatment. The novel construction for the mandrel and the tubing hanger eliminates the requirement for a packoff assembly attached to a bottom of the mandrel and thereby permits the mandrel to have a larger internal diameter for increasing the transfer rate of production stimulation fluids through the wellhead. The advantages include a mandrel which accommodates faster transfer rates, is less prone to catch on constrictions as the mandrel is stroked through the wellhead and requires no packoff assembly for sealing within the production tubing. A further advantage is the provision of a mandrel for a wellhead isolation tool that eliminates all joints between the high pressure tubing connector and the production tubing to minimize washout during production stimulation using abrasive proppants.
