  • Patent number: 3995092
    Abstract: A laminated threaded rod comprises a number of pressed and glued together laminated sections extending longitudinally of the rod. The laminations of all of the sections extend substantially perpendicularly to the superficies of the rod at least at four different locations on the superficies and which are opposed to each other cross-wise within a cross-sectional plane of the rod. The glued together laminated sections can have various initial cross-sections prior to being machined into rounded threaded form such as triangular or rectangular, and the number of sections can also be varied, there being, for example, four or eight triangular sections or three rectangular sections.

  • Patent number: 3990558
    Abstract: 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.

  • Patent number: 3988622
    Abstract: 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.

  • Patent number: 3987388
    Abstract: A current limiting device includes a duct containing a current-limiting material therein which serves to interconnect two spaced terminals but which is evaporable when subjected to an over-current flowing through the material between the terminals. The wall forming this duct includes a region made from a highly-temperature-resistant material which has a relatively small cross-section that connects with another region of the duct having a larger cross-section, and the wall part forming the region of smaller cross-section is surrounded by a resistor member connected electrically in parallel with the current-limiting material disposed therein and which has a resistance value such that the current-limiting material is relieved of current following onset of an over-current condition.

  • Patent number: 3985284
    Abstract: A multi-layered packing material in the form of a web for use in constructing blanks to be erected into finished packaging containers comprises a relatively stiff base layer made of paper, cardboard or foamed plastic coated preferably on both sides with a layer of thermoplastic material, e.g. polyethylene. The laminated packing material may also include aluminum foil to establish a gas-proof barrier. At least one of the edges of the laminated packing material is provided with a narrow edge zone of a heat-activatable bonding agent of the same thickness as the web such as a mixture of solid hydrocarbons which is mechanically stable but elastic at normal temperature and has a relatively low melting temperature range. The edge zone consisting of the heat-activatable bonding agent is utilized in establishing a butt type joint between it and an adjacent panel or other planar part of the container when erected.

  • Patent number: 3982849
    Abstract: 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.

  • Patent number: 3983358
    Abstract: A scanning device for use in conjunction with TIG spot welding lugs on a commutator to taps on the winding of a rotor includes a scanning arm pivotally mounted on a support which can be actuated between a raised position wherein the lower end of a scanning finger depending from the lower end of the scanning arm is disposed outside a circle circumscribed by the ends of the commutator lugs and a lowered position wherein the scanning finger projects into the gaps existing between adjacent lugs. A welding order is released in response to deflection of the scanning arm brought about by contact between the scanning finger and a lug upon rotation of the rotor as well as an order to actuate the support to its raised position for a predetermined period, the support then being returned to its lowered position for scanning the next adjacent lug.

  • Patent number: 3981444
    Abstract: 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.
