Title: Continuous method for manufacturing a laminated electrolyte and electrode assembly
Inventor: HEDRICH PETER
IPC: C25B9/23
Filed: 1998-12-22
Abstract: A continuous method manufactures a laminated electrolyte and electrode assembly ("laminated assembly") comprising at least one pre-formed electrode layer, at least one catalyst layer and at least one electrolyte layer for an electrochemical cell. The method comprises forming at least one of the catalyst or electrolyte layers in situ and using it as a laminating medium. The method produces a laminated assembly in a continuous sheet, which may be later cut to size and shape for use in electrochemical cells. The method may comprise co-extruding granular catalyst and/or electrolyte materials. In one embodiment, the catalyst and electrolyte layers are co-extruded. The coextruded tri-layer extrusion is laminated with immediately adjacent pre-formed electrode layers. In another embodiment the catalyst layer is extruded and the catalyst layer acts as the laminating medium between immediately adjacent preformed electrode and electrolyte layers. In a further embodiment the catalyst layers are applied to two separate pre-formed electrode layers, and the catalyst coated electrode layers are laminated with an electrolyte layer formed in situ which serves as the laminating medium.

Filed: 1999-03-19
Abstract: A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor. These chemically sensitive resistors can each be connected in series with a reference resistor, between a reference voltage and ground, such that an analog signal is established for each chemically sensitive resistor. The resulting analog signals are supplied to an analog-to-digital converter, to produce corresponding digital signals. These digital signals are appropriately analyzed for vapor identification.

Abstract: A message to be communicated over an unsecure communications link (16) is fragmented (26) into a plurality of packets (each of perhaps varying length).  The packets are then individually transmitted (20) over the unsecure communications link with an introduced varying (perhaps, randomly or pseudo-randomly) selected inter-packet time interval (delay). Received packets are then reassembled (36) to regenerate the original message. To provide enhanced security against eavesdropping, the packets are not only transmitted in a non-timely manner (28) with the inter-packet time delay, but are also either routed (32) over different transmission paths (34) supported by the communications link or disordered (30) in a random or pseudo-random manner prior to transmission.

Title: Extraction of bitumen from bitumen froth and biotreatment of bitumen froth tailings generated from tar sands
Inventor: BUDDEN JULIA R
IPC: C10G32/00
Filed: 1999-08-27
Abstract: A process for the extraction of bitumen from bitumen froth generated from tar sands is disclosed. In this process, bitumen froth (9) is extracted from tar sands using a water process without requiring the use of caustic soda. The froth is treated in a counter-current decantation circuit with a paraffinic solvent to remove precipitated asphaltenes, water, and solids from the bitumen froth. A dilute bitumen product is produced having a final water and solids contents of about 0.01 to about 1 % by weight (32). This renders the dilute bitumen product amenable to direct hydrocracking. The process advantageously avoids the production of tailings sludges caused by clay dispersions. The present invention also includes a novel process for the biotreatment of bitumen froth tailings (47-52) resulting in a reduced amount of waste products and byproducts.

Title: Droplet deposition apparatus
Inventor: DIXON MICHAEL JOHN
IPC: B41J2/04
Filed: 1999-12-24
Abstract: Droplet deposition apparatus comprises an array of fluid chambers (300, 310), each chamber communicating with an orifice for droplet ejection, a common fluid inlet manifold (220) and a common fluid outlet manifold (210, 230), and means for generating a fluid flow into the inlet manifold, though each chamber in the array and into the outlet manifold, the fluid flow through each chamber being sufficient to prevent foreign bodies in the fluid from lodging in the orifice. Each chamber is associated with means for effecting droplet ejection from the orifice simultaneously with the fluid flow through the chamber. The resistance to flow of one of the inlet and outlet manifolds is chosen such that the pressure at a fluid inlet to any chamber in the array varies between any two chambers by an amount less than that which would give rise to significant differences in droplet ejection properties between these two chambers.
