Title: Water filtering
Inventor: ROBERTSON EDWARD J
IPC: C02F1/28
Filed: 1996-10-30
Abstract: A reservoir of a water filtration system carries a projection such as a fin on its outer surface.  The reservoir is removably received in a housing, such as a pitcher, such that the projection engages a shelf in the housing.  A passage in the reservoir can have a nonuniform taper that corresponds to the outer surface of a water filtration cartridge.  A grippable member such as an indicator dial can be movably attached to the outer surface of the housing.  For each orientation, use indicia on the grippable member align with use indicia on the outer surface of the housing in a unique visual configuration.  A water filter cartridge for the filtration system can have an inner surface that extends between a water inlet and a water outlet.  One portion of the inner surface starts at the water inlet and joins at its other end to a second portion of the inner surface. The second portion of the inner surface is about as long as the first portion, and is tapered.  The small-diameter end of the tapered portion extends to the water outlet of the filter cartridge.  The cartridge can also have two ridges on the inner surface of the housing between the water inlet and outlet, both projecting inward towards the center axis of the housing.  The innermost end of the ridge closest to the water inlet is farther from the center axis than the innermost end of the other ridge.

Title: Drum dryer having aggregate cooled shielding flights
Inventor: MILSTEAD JOHN
IPC: F27B7/38
Filed: 1995-05-02
Abstract: A rotary drum dryer (12) has devices for cooling shielding flights (44) located in the combustion zone of the drum. The devices comprise cooling flights (46) which rotate with the drum to scoop up relatively small amounts of virgin aggregate from aggregate accumulated in the lower portion of the drum and to shower this aggregate over the outer radial surface of the shielding flights (44) upon further rotation of the drum, thereby cooling the shielding flights without substantially decreasing the mean temperature of the aggregate. Cooling efficiency is enhanced by the continuous cascading of fresh aggregate over the shielding flights from the cooling flights (46) through a substantial portion of the drum's rotation. The cooling flights and shielding flights preferably cooperate to limit or even prevent the showering of materials into the burner flame (24) and thus inhibit burner flame quenching and accompanying emissions. Particularly preferred cooling flights take the form of auxiliary flights which can be easily adapted to existing shielding flight designs.

Title: Operation right interlinking method and cooperative working method for shared application programs
Inventor: MIZUNO HIROMI
IPC: G06F15/00
Filed: 1997-01-07
Abstract: The invention provides an operation right interlinking method and a cooperative working method wherein, when a plurality of shared application programs operate cooperatively with each other to effect a cooperative work, operation rights of the shared application programs are always possessed by a same terminal so that a work can be performed efficiently without an inconsistency.  To this end, the operation rights of the shared application programs are controlled in an interlinking relationship with each other.  When a request for an operation right is issued to a first application program of a first terminal, the first application program requests a first application program of a second terminal for transmission of the operation right and sends an operation right change notification to a second application program of the first terminal whose operation right is to be interlinked with the first application program.  Upon reception of the operation right change notification, the second application program of the first terminal requests a second application program of the second terminal based on the operation right change notification.

Abstract: In the oil production facilities oil coming from wells consists a mixture of water, gas and a percentage of sand. To separate oil by the convectional process, this mixture is discharged into a vessel called water knock-out vessel. There oil, gas, water and sand are separated through effect of gravity effect and settling process. Waste gas is passed to a waste-gas incinerator ,oil is pumped to an oil treater and water is disposed. The water knock-out vessel has to be de-sanded from time to time therefore the production has to be stopped, the sand is removed and the remaining sand is then washed out. This de-sanding procedure is very costly, as well as the shut down of the plant which causes reduction of the production and losses for the business. The new de-sanding system is based on a flotation technology combined with vortex effect. The oil mixture coming from the wells will be fed directly to this system, before discharging to the water knock-out vessel. The mixture passes through de-gassing tank for waste gas separation. After gas separation the oil slurry passes through the aerator cells to introduce air to the oil. There after, separation procedure will take place, when the mixture is entered with a vortex effect to a multi stage separator system.The oil, water and sand are then separated and each can be discharged from the system. Depending on the percentage of remaining water and fine sand, the de-sanded oil can be discharged to the water knock-out vessel for further processing, or directly to the treater facility. The main advantage of this process is avoiding shut down of the plant for removal of the sand produced. In most cases, water knock out vessel can also be eliminated.
