Title: Improved ulpa filter
Inventor: GEORGE NELSON A
IPC: B01D69/12
Filed: 1994-09-15
Abstract: An improved filter unit suitable for use in a variety of clean air filtration applications is taught. The filter unit employs continuous microporous filtration membranes, such as expanded polytetrafluoroethylene, to deliver exceptional filtration efficiencies on the order of 99.99999% at 0.1 µm with minimal pressure drop produced across the filter. Additionally, the filter unit of the present invention has the further advantage of avoiding many previous deficiencies in HEPA and ULPA filter units, such as filter contamination from shedding particles and/or out-gassing, and limitations on chemicals to which the filter can be exposed withoutdeterioration. As a result, the present invention provides a cleaner and more durable filter that can be used to address contamination problems in many different industries, such as electronics and pharmaceuticals.

Patent CA-2166597-A1 (CA)
Inventor: HERZOG WILLIAM E
IPC: E01H3/02
Filed: 1996-01-04
Abstract: A pressurization system for a tank on a water truck includes a pipe connected at one end via a remotely controllable three-way valve directly into the engine exhaust system of the truck and at the other end into a top portion of the water tank.  Engine exhaust is thus selectively introduced into the water tank to pressurize the tank.  The tank includes a top-mounted fill opening with an internal, counter-weighted flapper valve.  With the internal flapper valve, the truck can be driven beneath a high volume water source and water from the source, when it hits the counter-weighted flapper valve, opens the valve by urging the flapper against the action of the counter-weight, but the flapper valve is once again closed by action of the counter-weight when water flow ceases.  An anti-siphon orifice in a water outlet conduit serves to prevent water from freezing in the outlet conduit once pressurization is stopped.

Title: ATM Bus System
Inventor: SAITO KAZUO
IPC: H04L12/56
Filed: 1996-03-08
Abstract: An ATM bus 11 is a bus for performing data transfers in an asynchronous transfer mode, while a control bus 8 is a bus for transferring control signals sent out by a central control section 1 in order to control bus users 10a ~ 10d.      The bus users 10a ~ 10d and a bus arbitration circuit 12 are connected to this ATM bus. The bus users 10A ~ 10d are ATM bus users. When the bus users 10a ~ 10d simultaneously issue bus use requests, the bus arbitration circuit 12 selects a single bus use request from among these requests.      Then, all of the bus users are sent data identifying the bus user which issued the selected bus use request. As a result, only the selected bus user begins a data transfer operation using the ATM bus 11.

Title: Modified Latex
Inventor: KROYER KARL KRISTIAN KOBS
IPC: D04H1/64
Filed: 1994-10-28
Abstract: A method is disclosed for the use of a modified latex making it possible to provide a combination of hydrogene bonds and covalent bonds in fibrous products. A softener product is added to the binder solution before its application onto the fibrous product. The softener is a natural latex added to a latex binder contained in a water suspension. It has surprisingly shown that a product manufactured with a modified latex will occur more soft and silky and also stronger than products made by use of a normal latex binder. The modified latex is especially suitable for use in a process in which a mechanical softening treatment is effected on the fibrous product.
