Patent CA-2317180-A1 (CA)
Title: Treatment of metals for coating or activation
Inventor: BALDI ALPHONSO L
IPC: C06B45/14
Filed: 1990-09-13
Abstract: Coating with high-melting metals can be simplified by alloying high-melting metal with sufficient aluminum to make low-melting alloy that is applied, bonded in place, and then subjected to the leaching out of some or most of the aluminum.      The resulting surface is porous and will receive and hold top coatings. Leached surface can be pyrophoric and top coating can be exothermically combustible. Pyrophoric powder can also be coated on boron or carbon fibers or sintered with combustible particles. Porosity can be created by subjecting workpiece to diffusion conditions in contact with depleting material such as powdered nickel or high-nickel aluminides or cobalt or high-cobalt aluminides. Aluminum particles can be electrophoretically deposited on foil and then diffused in.    Leaching aluminum out with caustic is improved when a little H2O2 is present in the caustic. Subsequent treatment of the leached surface with weak acid further improves pyrophoricity, and folding of the pyrophoric member extends its pyrophorically-generated high temperature dwell. Resin foil containing pyrophoric particles makes effective decoy.

Title: Plant for the treatment of residue
Inventor: TESCHERS LEONHARD
IPC: B03B9/04
Filed: 1999-05-12
Abstract: The aim of the invention is to continuously separate inhomogeneous remaining material (IR) generated by a pyrolysis installation such that the remaining material is sorted as completely as possible. To this end, specially selected components are combined with one another in an advantageous arrangement. An essential element of the installation is the separation of coarse remaining material (GR) in a coarse sieve (2) and the subsequent separation of the residual remaining material (R) in a zigzag separator (6) into a light remaining material (LR) and into a heavy remaining material (SR). Using the installation, the portions containing carbon are, in particular, separated from the remaining material (R). The individual components are constructed such that they are, for the most part, self-cleaning in order to enable an operation which is free of interruptions.

IPC: C25C3/06
Filed: 1999-07-30
Abstract: A cell for the electrowinning of aluminium comprising one or more anodes (10 ), each having a metal-based anode substrate, for instance comprising a metal core (11) covered with an metal layer 12, an oxygen barrier layer (13), one or more intermediate layers (14; 14A, 14B) and an iron layer (15). The anode substrate is covered with an electrochemically active transition metal oxide  layer, in particular an iron oxide-based outside layer (16) such as a hemati te- based layer, which remains dimensionally stable during operation in a cell b y maintaining in the electrolyte a sufficient concentration of iron species an d dissolved alumina. The cell operating temperature is sufficiently low so tha t the required concentration of iron species in the electrolyte (5) is limited  by the reduced solubility of iron species in the electrolyte at the operatin g temperature, which consequently limits the contamination of the product aluminium by iron to an acceptable level. The iron oxide-based layer (16) is  usually an applied coating or an oxidised surface of a substrate (11, 12, 13 , 14, 15), the surface (15) of which contains iron.

Title: Method and apparatus for real time down-link scheduling in a satellite communications network
Inventor: LINSKY STUART T
IPC: H04B7/185
Filed: 2001-05-18
Abstract: A method and apparatus are provided for scheduling, in real-time, the order in which data packets from a plurality of uplink channels 40-55 are organized in a downlink channel 60 of a satellite communications network 5. The satellite 10 includes uplink and downlink channels for conveying data packets over channels between user terminals 15-30, ground stations 35 and other user terminals. Queues 104-110 in the satellite 10 collect data packets from uplinks 40-55 and output the data packets to the downlink 60 using a bandwidth that is dynamically allocated. A scheduler 152 allocates the bandwidth to at least one queue 104-110 and continuously changes the amount of bandwidth allocated to each active queue 104-110 while the queue 104-110 is buffering data packets between the uplinks 40-55 and downlink 60. The scheduler 152 allocates bandwidth based upon a priority-class packet service schedule 200 calculated based upon traffic parameters associated with each active queue 104-110 (steps 306 and 308).
