Abstract: ABSTRACT OF THE DISCLOSURE        A converter of meter-gauge readings is used for auto-matic remote checking of the readings of a gas, a water or power meter-gauge.  The converter serves to make a decimal-binary conversion of the readings of such a meter-gauge to enable transmission over a telephone channel.  The readings of the figure-wheel in such a meter-gauge are rendered into binary codes by binary cams and the oscillation of oscillators matching the binary codes is controlled and converted to an AC signal.  The frequency of the AC signal fits into the allowable frequency band of the transmitting means such as a telephone channel.  The use of a power source or a complicated electric circuit is thus avoided, and the converter can be attached to the existing meter-gauge without modification.

Abstract: Abstract In a method of and assembly for sorting a granular two- or multi-component mixture, containing a number p of granular, polydisperse  solid components to be sorted out the particles of which differ in density and/or shape and have at least partially overlapping particle size and settling rate (partic-ulate characteristics) distributions the mixture, in which the components are present sortable, is subjected to two dry classification steps in which different particulate charac-teristics of the particles are decisive. First, The feed mexure is dry classified in a first step, in particular by sieving or wind sifting, into a greater number of classes of a first particulate characteristic, (into screening classes or settling rate classes), which are sufficiently narrow with a view to the subsequent separation of the components to be sorted out and in which the fractions of the second particulate characteristic (the settling rate fractions or screening fractions) of the individual components are contained separately or consecutively or only slightly overlapping. Then the components are separated in a second step by subjecting each class obtained to further classifying, in series of successive classifications, in particular wind siftings or sievings, so as to obtain the sorted out components pure or enriched. The selection of the width of the classes in the first step must be made, in consideration of the desired and possible sorting by classify-ing in the second step, in which the second particulate char-acteristic of the particles is decisive, such that graduation of the cut-off limits of the classifying in the second step is made possible in a manner at which the two limits of the second particulate characteristic determin the particles to be re-covered of each fraction which does contain particles of the components to be sorted out. Thus the largest particles of the respective lighter component, to be sorted out, can be separated from the smallest particles of the respective heavier component to be sorted out.            Fig. 4

Abstract: Abstract of the Disclosure A transaction execution system is provided in which key initiated transaction requests at a terminal remote from and in communication with a host data processing system are processed at the terminal under the selective control of the host. Each active transaction key at the terminal keyboard is assigned one of three different states by a financial institution table.  The table provides keyboard customization by selecting one of a plurality of different groups of key states for the different keys arrived at by combining the key states in a custom key set table with the states in a base key set table in response to information from a credit card entered by a consumer.  Transactions requested by keys assigned a standard state are processed at the terminal without further data input being required of the consumer.  Transactions requested by keys having a data entry state are also handled within the terminal and with the additional consumer entered data required to complete the transaction being requested by and received by the terminal using sets of messages previously stored in the terminal by the host data processing system.  Transactions designated by an interactive key state take place within and involve interactive communi-cation between both the terminal and the host  enabling the responses and other communications generated by the host in connection with a transaction for a particular customer to be customized and providing for greater and more varied transactions including such things as bill paying in which funds are transferred between accounts in the host.  Message storage within the terminal and communication of messages to the terminal from the host are greatly simplified by storage of segments of messages at the terminal.  Frequently repeated phrases can then be incorporated into a message as it is readied for display at the terminal by storing the phrases as segments and thereafter simply identifying them in message definitions communicated to the terminal from the host or stored at the terminal.

Abstract: ABSTRACT OF THE DISCLOSURE In the course of completing a production well in a heavy oil or tar sand reservoir arranged for frontal displacement, thermal drive from at least one injection well, the well is divided into separate, non-communicating lower and upper zones.  The lower is connected with the reservoir by perforations; the upper by a large gravel packed zone and preferably a sand screen.          The completion process involves starting a local combustion drive adjacent to the bottom of the well by injecting compressed air through the perforations while preventing upward migration of the combustion zone in the vicinity of the well by injection of water or dilute aqueous soap solution through the screen and gravel packed zone.  After a suitable time, generally of the order of a month or less, air injection is stopped.  Production is started through the screen (no workover or killing opera-tion needed).          After producing some or all of the combustion product gas and locally heated oil, the well is still hot, with a region of high permeability adjacent to the gravel packed zone, ready to produce fluids and/or gas from a distant injection well.      Should further heating be needed later in the life of this well, the annular space normally used for production can be displaced with a soap solution after which the local heating step is repeated.

Abstract: ABSTRACT         A charge transfer image sensor device having an anti-blooming function is disclosed.          The device comprises a semiconductor substrate, a plurality of sensor region which store signal charges in response to the incident radiation during a predetermined period, a shift register to read out the stored signal charges.  The anti-blooming function is achieved by applying alternately voltage to the area adjacent to the sensor regions during a predetermined period to put the surface of the semiconductor substrate into an accumulation or depletion state.  The electrons trapped at the surface state are recombined with majority carriers of the substrate when the area is made an accumulation one and the excess signal charges are trapped at the surface state which is vacant by the previous recombination when the area is made depletion.  Thus the excess charges are removed through the surface state which results in anti-blooming.
