Patent EP-0040023-A1 (EP)
Inventor: PATERSON ALAN
IPC: C23C8/22
Filed: 1981-04-28
Abstract: Carrier gases formed by the reaction of rich mixtures of hydrocarbon and air and heretofore considered unsuitablefor gas carburizing can be used for gas carburizing if introduced into the heat treamtment chamber (4) at or below a specified flow rate. This flow rate is inversely proportional to the amount of CO 2  and H 2 0 present in the carrier gas and can be increased by, for example, removing H 2 0 from the gas. The invention has particular commercial value since it enables exothermic gas generators (8) to be used for providing carrier gas for gas carburizing with excellent control of the carbon potential by monitoring the reacted furnace atmosphere and making hydrocarbon additions in the usual way. Three forms of apparatus are also described which may be used for producing suitable carrier gases in the heat treatment chamber (4) itself.

Abstract: A method of making a radiopharmaceutical composition by mixing an aqueous solution of pertechnetate with a reducing agent comprising tin metal or stannous ion to reduce the pertechnetate and a complexing agent to form a complex with the reduced technetium, is characterized by incorporating nitrate and or nitrite in an amount to diminish oxidation of Sn 2-  to Sn 4- , and hence to prevent re-oxidation of technetium to pertechnetate, during preparation and storage of the complex. Nitrate and nitrite are superior to organic antioxidants previously proposed. 
     A reagent for the purpose comprises the reducing agent, the complexing agent and tne nitrate and,or nitrite usually in a sterile freeze-dried state.

Abstract: A digital scan converter is disclosed wherein signal information supplied by a sector scanning surveillance system relative to a polar coordinate system is converted to a signal for driving a television-type display or other Cartesian coordinate device by: (a) sampling the signal associated with each consecutive scanning path of the surveillance system at a rate determined by the azimuthal angle that defines the scanning path of interest; (b) storing each set of signal samples as a column of data in a rectangular memory array; (c) accessing the stored data on a row-by-row basis; and (d) utilizing a previously determined mapping strategy to cause each accessed signal sample to form a segment of a line of display within the Cartesian-formulated display devices so that the length of the segment formed by each signal sample is determined by the row and column address of the storage location that is associated therewith when forming a television compatible signal, each signal sample dictates video signal level during a portion of a corresponding horizontal sweep period that is determined by the mapping strategy.

Abstract: A system is described for removing C0 2  from the manufactured process gas in an SNG manufacturing plant, the system operating the hot carbonate process wherein hot potassium carbonate solution absorbs C0 2  from the process gas under pressure in an absorber column 1 and is regenerated by pressure reduction and steam stripping in a regenerator column 14 and a reboiler 17 before being returned to the absorber by a circulating pump 7. The system is completely automated and is controlled by a computer (Figure 2) so that start-up, running and shut-down of the system is carried out automatically upon initiation by an operator, whereby the system is particularly suited for use in peak load SNG plants. For this purpose the system includes a solution make up tank 30, a solution storage tank 31, and a flushing water collection tank 32, preferably has all of its surfaces contacted by potassium carbonate solution made of stainless steel, and has sensors (F, L, T, P, AN, SG and PH) and valve switches for transmitting information to the computer relating to the state of the system. The computer is programmed to operate the sequences of operation necessary to achieve the start-up, running and shut-down of the system, operate loop controls on the solution levels in the absorber and regenerator columns, and on the rates of flow of solution to the absorber and of steam to the reboiler, and also to monitor the system parameters and to display data and signal alarm conditions.

Abstract: In a digital data communications system having a plurality of slaved data transceivers transmitting data to, and receiving data from, a master station, the master station classifies a received signal, in each of a multiplicity of bit time intervals as one or the other of the pair of binary signal states. The received binary signal state is echoed to all of the slaved stations, to cause those stations which did not previously transmit that binary state to cease transmitting data. Those slave stations which transmitted the echoed previous bit binary state then transmit the next bit of data, which is again echoed. Slaved stations receiving bit echoes which are different from the previous bit sent will know that there has been a collision and that the master station did not receive their bit of data, whereby the number of slave stations transmitting is reduced, in successive bit time intervals, unit only one slave station remains transmitting. The initial portion of the message of the one remaining station need not be repeated, whereby system time is not lost.

Abstract: Bei einem Abgasturbolader mit einer Radial - oder Axialturbine und zumindest teilweise radial durchströmten Turbinenleitapparat (8) ermöglicht ein verstellbarer Ringschieber (2) eine stufenlose Steuerung des Turbinenzuströmquerschnittes. Die Verstellung des Ringschiebers, welcher zwischen Leitapparat (8) und Laufschaufeln (1) gleitet, erfolgt durch eine axiale Verschiebung. Die vom Gasstrom umströmte Stirnkante ist strömungskonform ausgebildet, um Ablösungen stromabwärts zu vermeiden. Bei Radialturbinen bleibt der Zuströmwinkel zu den Turbinenlaufschaufeln im ganzen Regelbereich etwa konstant. Damit entfällt der Stossverlust an den Turbinenlaufschaufeln weitgehend. Die stufenlose Steuerung des Turbinenzustromquerschnittes resultiert in einem verbesserten Teillastverhalten des aufgeladenen Motors, indem die dem Motor zugeführte Luftmenge den Verbrennungsverhaltnissen angepasst und ein rauchfreier Betrieb im ganzen Drehzahlbereich erzielt wird.
