Patent number: 3990558Abstract: A method and apparatus is described for preparing and assessing machine readable payment documents such as bank or postal checks to avoid fraud. The checks are prepared by enciphering the serial number and the amount for which the check is made out with secret code data to provide a crypto number which is printed on the check with the serial number and the amount. The check is assessed as valid by reading out the printed data and enciphering the amount and serial number with the same secret code data as used when preparing the check to provide a crypto number which is compared with the crypto number read from the check. If the two crypto numbers are the same the check is assessed as valid.The crypto number can be derived from additional data such as the credit card number of the person making out the check, the time and date and the number of the machine preparing the document.Type: GrantFiled: October 7, 1974Date of Patent: November 9, 1976Assignee: Gretag AktiengesellschaftInventor: Kurt Ehrat

Patent number: 3988622Abstract: The laminated stator component of a dynamo-electric machine is prestressed in such manner as to free the laminations from temperature-induced compressive stresses that otherwise may result in displacement of the laminations. In particular, the stator lamination assembly is prestressed in tension, with respect to the cold condition, in an outward direction, by an amount corresponding at least approximately to the difference in expansion between the laminations fixed in the stator frame and those freely expanded at the same temperature. The laminations are held continuously in tension, preferably in a radially outwards direction, in the stator frame or foundation, which is thus at least partly pre-compressed inwards, in such manner that under all practicable operating temperatures of the machine, no compressive stresses can occur in the laminations.Type: GrantFiled: August 6, 1975Date of Patent: October 26, 1976Assignee: BBC Brown Boveri & Company LimitedInventor: Mihailo Starcevic

Patent number: 3982849Abstract: A low pressure multi-stage axial flow steam turbine comprises an outer housing and an inner housing structure constituting a carrier for the rows of guide blading of the various stages. A steam inflow housing located within the inner housing structure forms the boundary of a crescent-shaped intake duct which surrounds and admits steam to the first stage guide blading which flows through the duct in the same direction as that in which the turbine rotor rotates, and the cross sectional area of the intake duct decreases progressively in the direction of steam flow therethrough such that the tangential components of the steam velocity conform to a predetermined function. The curvature of the intake duct at the inner periphery thereof increases progressively in the direction of steam flow therethrough such that the radial components of the steam velocity conform to a second predetermined function.Type: GrantFiled: April 23, 1975Date of Patent: September 28, 1976Assignee: BBC Brown Boveri & Company LimitedInventors: Felix Bernasconi, Heinz Brunner, Pierre Meylan

Patent number: 3981444Abstract: The invention involves a closed loop control method and apparatus for starting up a steam-heated heat exchanger by controlling the heating-steam pressure. According to the invention a correcting variable is established by a controller from an actual pressure value, measured by an actual value transmitter, and from a reference value, generated by a reference value generating device, the heating-steam pressure being modified by at least one control valve on the basis of said correcting variable. The pressure reference value S is selected from three pressure set values, S.sub.T, S.sub.P1 and S.sub.P2, the lesser value of S.sub.T and S.sub.P1 being established as an intermediate pressure set value S' (that is, S' = Min (S.sub.T, S.sub.P1)), and the pressure reference value S is selected as being the greater value of S' and S.sub.P2 (that is, S = Max (S', S.sub.P2)), where S.sub.T represents that permissible maximum desired pressure value which is a function of the momentary metal temperature T.sub.Type: GrantFiled: May 29, 1975Date of Patent: September 21, 1976Assignee: BBC Brown Boveri & Company LimitedInventor: Gerhard Weiss
