Patent EP-0114189-A2 (EP)
Inventor: ABRAHAM DENNIS GEORGE
IPC: H04N1/417
Filed: 1983-09-20
Abstract: A system for compressing image data, when input in the form of run length coded sequential lines of image data, encodes variable length segments of the current to-be-coded line two dimensionally in terms of the detected relationship between the constants of five registers (18, 20, 22, 24, 26). The run length code words of the current line and the immediately previous reference line are accessed sequentially and selectively from respective FIFO buffers (12 14) under the control of switching logic (16) which also establishes a pattern of connections, unique to the generated code representing the immediately previous current line segment, coupling the outputs of the registers and the buffers to the inputs of the registers through adders to establish the next set of five values in terms of which segment coding takes place. One dimensional coding can be accommodated.

Abstract: The present invention relates to new compositions and methods of preparation of deflocculants for water-base mud additives. The disclosed materials are low molecular weight terpolymers and graft copolymers consisting essentially of monovalent salts of (1) 5 to 50% by weight of tetrahydrophthalic acid (THPA); (2) 10 to 70% by weight of acrylic acid (AA); (3) 5 to 50% by weight of 2-acrylamido-2-methylpropane sulfonic acid (AMPS); and (4) 0 to 70% by weight of lignosulfonate units. The unique compositions and processes of terpolymers and graft copolymers provide excellent drilling fluid additives which significantly control the viscosity, yield point, gel strength, and fluid loss of drilling fluids over a wide range of temperatures and in the presence of contaminants such as salt, lime, cement, gypsum and drilled solids.

Abstract: A method of treating bitumen and/or oil containing sludges or tailings is disclosed which comprises the steps of mixing the sludge or tailings with a secondary carbonaceous fuel reducing the toxic substances and the moisture content of the mixture and introducing the mixture into a combustor or gasifier for combustion or gasification. The method may be used to process the middlings and froth treatment tailings from the tar sands hot water extraction process. The method may also be used to treat the sludges reclaimed from tar sands tailings ponds, or from harbour maintenance dredging operations, or the slurries produced as 'produced water' in in situ heavy oil production or other similar sludges. 
     The method is particularly suitable for use in combination with a flooded mine tar sands mining method.

Abstract: A process for producing pig iron from iron ore concentrate, at which in a reactor vessel iron ore concentrate, coal, oxygen gas and slag formers are injected beneath the surface of a molten iron bath. According to the invention, the ratio CO 2 /CO in the waste gas (11) from the reactor (2) is caused to increase to a value higher than corresponding to the condition of equilibrium at atmospheric pressure. Hereby a greater heat development is caused to take place in the bath for a certain coal amount. The injected amount of coal in relation to injected amount of concentrate is predetermined to be sufficient for finally reducing pre-reduced iron ore concentrate (4) in the reactor (2). According to the invention, CO and H 2  in the waste gas is passed to a pre-reduction step (1), where unreduced iron ore concentrate is pre-reduced and thereafter can be injected into the reactor. 
     According to a preferred embodiment, the reactor (2) is pressurized to cause the CO 2 /CO ratio to increase.

Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Belüftung von Abwasser oder dgl. Medien in Belüftungs becken mittels einer unter der Wasseroberfläche angeordneten Belüftungsfläche (2/4). Der nächstliegende Stand der Technik wird durch eine Belüftungseinrichtung definiert, in deren ausgesteiftem Doppelspannrahmen gemeinsam eine Tragfolie und eine dieser aufliegenden Belüftungsmembrane eingespannt sind. Ein wesentlicher Nachteil dieser Konzeption ist deren auf die Belüftungsfläche bezogenes hohes Gewicht, die durch die Membrane nieder haltenden Stege gegebene Störung der Gleichmäßigkeit der Luftverteilung über die Belüfterfläche und deren bei Belastung gegebene "Wanderungsmöglichkeit" unterhalb der Stege sowie letztlich die schlechte Manipulierbarkeit der Gesamteinrichtung im Hinblick auf deren Gewicht. Die erfindungsgemäße Konzeption sieht demgegenüber eine in sich starre, selbsttragende, oder porösen oder mit Durchbrüchen versehene, durch eine elastische Membrane (4) bespannte Tragfläche (2) vor, in deren Schwerpunkt (10) oder in einer Reihe über eine Schwerlinie (11) verteilt, die Luftzuführung (1) in mindestens einem Umlenkbereich (3) auftrifft, und zu der gegenüber diesem um ein geringes Maß höhenversetzter Peripherie (12) hin mit abnehmendem Luftdruck in das zu belüftende Wasser überführt wird. Die Belüftungsfläche kann schwenkbar ausgeführt werden, der Querschnitt der Tragfläche kann pyramiden-, keil-, kreis- oder kegelstumpfförmig oder auch konkav/konvex gewölbt ausgeführt sein. Als Grundform ist die Kreisform bzw. die rechteckige bis mehreckige Form vorgesehen.

Abstract: A greatly improved aseptic processing apparatus and method for pumpable foods is provided which gives accurate, uniform aseptic cooking conditions (e.g., time, temperature and pressure) while at the same time preserving the integrity of particulates in the food product. In preferred forms, the apparatus includes a reciprocating piston food pump which generates a continuous product stream at a substantially constant nominal pressure. This stream is fed to a heat exchanger in order to elevate the temperature of the product, whereupon the stream passes through a holding tube to complete the aseptic cooking process. A metering device such as a rotary pump is located downstream of the holding tube for creating a substantially constant flow rate of product from the apparatus. Use of the downstream metering device in conjunction with an upstream constant pressure pump permits attainment of even, relatively high system pressures which in turn facilitates accurate temperature control and eliminates localized internal steam flashing which can deleteriously affect product quality. By virtue of the present apparatus and method, aseptic processing of low acid heterogeneous food products such as stews and chilies can be safely accomplished on a commercial scale.
