Abstract: ABSTRACT OF THE DISCLOSURE         In an on-line banking system including a central compu-ter and at least one remote terminal, a method of an apparatus for verifying that a holder of an identification card is authorized to complete a transaction at the terminal is disclosed.  Account num-ber data are machine read from the card, scrambled, and then com-pared to secret alphanumeric data, keyboard entered by the card holder at the terminal.  The secret alphanumeric data are converted to a digital signal, and the signal is converted into first and second signal portions.  The first signal portion is compared to the scrambled account number data.  If the comparison is positive, the second signal portion, along with keyboard-entered transaction data and account number data, is transmitted to the central com-puter.  Since only the second signal portion of the keyboard-en-tered secret data is transmitted on-line to the central computer, it is impossible to determine the entire secret data for gaining unauthorized use of the terminal by monitoring the line between the terminal and the central computer.  At the central computer, the second signal portion is compared with a reference signal stored on the authorized holder's account and addressed by the ac-count number data.  In response to a positive comparison, the cen-tral computer authorizes the remote terminal to complete the re-quested transaction.

Abstract: OIL RECOVERY BY VISCOUS WATERFLOODING            Abstract of the Disclosure Waterflooding process for the recovery of oil in which at least a portion of the injected water is thickened by the addition of a sulfonate surfactant and a C4-C6 aliphatic alcohol having a hydrocarbon chain link of at least 3 carbon atoms. The action of the surfactant-alcohol system in increasing the viscosity of the water varies with the monovalent salt salinity of the water and the ratio of the amount of the sulfonate surfactant to the sum of the amounts of the sulfonate surfactant and alcohol in the water. A relatively viscous aqueous mobility control slug containing a sulfonate-alcohol system as previously described may be preceded by an aqueous surfactant slug.  The aqueous solution of sulfonate surfactant and alcohol may be formulated and then aged for a time to allow the development of viscosity prior to injection into the oil reservoir.  This viscosity development may be accelerated by heating.

Abstract: ABSTRACT OF THE DISCLOSURE:        An apparatus operable to separate particulates, as dirt, dust and foreign materials, from air and deliver clean air to the operator's compartment of a tractor cab.  The apparatus has a motor-driver fan which moves air through a chamber sur-rounded with a cylindrical casing. The air moves through the chamber in a circumferential spiral direction whereby the particulates separate to an annular outside zone.  Spaced inclined vanes direct the central core of clean air to a clean air passage and the annular zone of air carrying parti-culates to an annular air discharge opening.  Cleans air is directed to a fiber filter which filters fine particulates from the air and disperses the air to the operator's compartment.

Abstract: COMBINE WITH MEANS FOR REDUCING THE BOUNCE OF ACCELERATED GRAIN                   ABSTRACT OF THE DISCLOSURE          A combine is provided with a threshing cylinder which rotates within a foraminous cage with a concave causing the grain to be separated from the severed crop.  The separated grain chaff, and other small lightweight portions of the crop being harvested, pass through the concave and other parts of the cage and thence through a transverse slot.         The material passing through the transverse slot is accelerated downwardly by a pair of counter-rotating accelerator rolls at substantially right angles to a rearward directed sheet or layer of air which serves to separate the lightweight material from the kernels of grain.  The lightweight material is blown rearwardly over the cleaning shoe assembly of the combine and the heavier grain kernels continue in their downwardly direction impacting with the grain pan below the accelerator rolls.  The grain pan of the longitudinally oscillated cleaning shoe assembly is provided with a plurali-ty of longitudinally spaced transverse baffles which extend upwardly and rearwardly terminating at a height which is sufficient to maintain a quantity of grain on the pan in spite of the oscillating movement to which it is subjected during operation.   The grain accelerated downwardly impacts with the grain retained on the grain pan, thereby substan-tially reducing the bounce of the grain as compared to that which would occur if the grain pan were of conventional construction wherein a substantial portion of the upward facing surface of the conventional grain pan would be exposed during operation.

Abstract: ABSTRACT OF THE DISCLOSURE             A copying machine has plural infeed capabilities, being provided for example with plural sheet supply units supply-ing sheets of different respective types or formats. A control panel is provided with a plurality of operator-activated dual-purpose select-and-start switches.  When the operator activates one of these switches, this both selects the respective infeed capability and also commands initiation of copying, so that the operator need not thereafter press a second switch merely to initiate copying.  The select-and-start switches are pushbutton switches the pushbuttons of which are translucent and provided, behind them, with respective signal lamps.  During a copying operation, the signal lamp behind the one of the select-and-start switches which commanded copying lights up, to indicate that copying is occurring.  If one of the supply units is exhausted, the respective signal lamp begins to blink, thereby indicating this to the operator. If the machine additionally has more than one mode of copying operation, e.g., a shifting optics scanning a stationary original and a transport unit transporting an original past a stationary optics, certain of the select-and-start switches can be additionally associated with these modes of copying operation, so that the user will not be able to select an infeed capability not appropriate for the selected mode of copying operation.

Title: Method for casting a plurality  of airfoils into a hub
Inventor: BLAZEK WILLIAM S
IPC: B22C23/02
Filed: 1978-11-14
Granted: 1982-02-09
Abstract: ABSTRACT Casting Method The present invention provides an improved method of forming a metal article having a plurality of airfoils which extend outwardly from a hub.  The metal airfoils are formed separately from the hub.  In forming a mold to cast the article, blade portions of the metal airfoils are coated with wax.  The metal airfoils are then placed in a circular array and are covered with a coating of liquid ceramic mold material.  This wet coating of ceramic mold material is dried to form an annular mold wall section having a plurality of recesses in which the blades of the metal airfoils are disposed.  The wax coating over the metal airfoil blades is subsequently removed from the recesses to provide space between the blades and the side walls of the recesses.  The annular mold wall section in which the blade containing recesses are formed is then connected with top and bottom mold sections to further define a mold cavity having a con-figuration corresponding to the hub portion of the article. Before casting, the mold is preheated to a relatively high temperature with the blade portions of the airfoils in their associated recesses.  As the mold is preheated, the metal airfoils expand to completely fill the recesses in which the blade portions of the airfoils are disposed. molten metal is then poured into the mold cavity and cooled to form a hub which interconnects the roots of the airfoils.
