Abstract: A change gear device (11) is disclosed of the type including a pair of substantially identical countershafts (27,29). The device includes a hydraulic PTO comprising a pair of fluid displacement mechanisms (71,73), each of which comprises a gerotor pump, and each of which receives input torque from one of the countershafts, by means of a pair of PTO input shafts (61,63), respectively.      The PTO input shafts are clutched to the respective countershafts. The pressurized fluid output of the two fluid displacement mechanisms (71,73) is combined at a port (133), or other suitable location. Preferably, the two displacement mechanisms (71,73) are substantially identical, such that equal torques are transmitted through the transmission countershafts (27,29) while the hydraulic PTO of the invention is in operation.

Abstract: A liquid filtering device includes a vessel and a filtering cartridge within the vessel. A pressure seal between the outlet venting of the cartridge includes a circumferentially extending skirt which is communicated with pressure at the inlet of the vessel, which is higher than the pressure of the outlet of the vessel by the pressure drop across the filtering cartridge.   Accordingly, the skirt is maintained in sealing engagement with a portion of the vessel or the support plate area by the vessel, thereby preventing bypass of fluid directly from the inlet to the outlet.

Abstract: A method of operating a blast furnace enables substantial improvement of gas permeability and liquid permeability for stable operation of the blast furnace, involves packing the core section with solid high strength, carbonaceous blocks prior to ignition of the furnace. The carbon blocks resist wearing and high temperature reaction over very long periods of operating time, greatly stabilizing the furnace. Because of the improved stabilization, gas permeability and liquid permeability, a low grade solid reducing agent can be substituted for a quantity of the high quality coke normally used for operating the blast furnace and furthermore enables injection of pulverized coal at a rate of at least 200 Kg/ton-pig.

Title: Custom class selection in automated mail processing
Inventor: KULIK GEORGE
IPC: G07B17/00
Filed: 1997-02-24
Granted: 2001-04-17
Abstract: A program controlled automatic mail processor includes custom rates software to facilitate processing of mixed mail streams for posting via a plurality of classes, without manual sorting of the mail into classes or manual selection of classes during mail processing.  A user defines a custom rates template, specifying classes and break point parameters (e.g. weight values) for controlling shifts between the selected classes.  The mail processor uses the template and previously stored standard postage rate tables to develop a custom rates rate table for processing mail in multiple classes.  Once the custom rates rate table is established, an operator can select any table from among the standard tables and one or more such custom rates rate tables.  The operator then begins feeding mail through the mail processor.  The mail processor checks a parameter value (e.g. weight) of each piece of mail and applies the appropriate postage value from the currently selected table.  In particular, if the user selects a custom rates rate table, the mail processes pieces of mail in a single stream in multiple mail classes, using class break point or classification information and corresponding rate information from the custom rates rate table.

Abstract: Apparatus and a process is provided for restricting that portion of the flow of water which is directed through a tube to refill the bowl of a toilet after a flush. Typically, the bowl refills before the toilet tank fills so that some water overflows the bowl and is wasted down the sewer. Accordingly, a conduit is connected to the discharge of the bowl refill tube. The conduit has a tapered bore which diminishes continuously from its inlet to its outlet. The diameter of the bore at the conduit's outlet does not permit sufficient water to discharge and refill the bowl after a flush. The conduit is formed of material which is readily cut. An objective bowl water is established. In a process of progressively trimming back the outlet of the conduit, an ever larger and larger diameter bore is exposed, increasing the amount of water discharged. Eventually, enough of the conduit is trimmed so that the operating water level in the bowl is tailored to the toilet's unique characteristics, reaching the objective water level and avoiding waste.

Title: A method and apparatus for dynamic data transfer
Inventor: DOUGLIS FREDERICK
IPC: H04L29/08
Filed: 1998-07-27
Granted: 2002-01-01
Abstract: A system and method for transferring information resources over a network from one source to another that reduces latency and bandwidth requirements on the network. The information resources are made up of at least a static and dynamic portion. A client requests information, and a server receives the request and then transmits to the requestor the desired information. The server may send both the static and dynamic portion of the information resource, or the server may sent only thedynamic portion of the resource, depending on the client's needs and the request made. By discriminating between the static and dynamic portions of an information resource in this way, less data must be sent from the server to the client on every access. Also, the computational load that is typical of servers on a network is shifted to the client, thereby reducing latency.
