Abstract: ABSTRACT            According to the invention there is a high nitrogen con-taining duplex stainless steel with high corrosion re-sistance and good structure stability.  Characteristic is the analysis of the alloy being in % by weight max 0.05 % C, 23 - 27 % Cr, 5.5 - 9.0 % Ni, 0.25 - 0.40 % N, max 0.8 % Si, max 1.2 % Mn, 3.5 - 4.9 % Mo, max 0.5 % Cu, max 0.5 % W, max 0.010 % S, max 0.5 % V, max 0.18 % Ce and Fe and normally present impurities, at which the contents of the alloying elements are so adjusted that the ferrite content after solution heat treatment at about 1075C amounts to 30 - 55 %.  The analysis of the steel is so optimized that it in solution heat treated, cold worked and also welded condition is particularly suitable for use in such environments where the presence of chloride ions gives rise to a high corrosivity.

Granted: 1991-07-02
Abstract: A B S T R A C T    A coating material is transferred to the surface of a   spreader-roll   from   a   spreader-mechanism.    The spreader-roll is partly wrapped by a strip of material. In the location where the said strip of material  is lifted   off   the   spreader-roll,   a   doctor-element, comprising   a   doctor-blade,   is   arranged   to   rest tangentially on the  spreader-roll.  The doctor-element thereby forms a rubbing distributing surface which faces the strip of material and ensures a smooth and uniform coating  of  the  coating  material  on  the  strip  of material.  The strip of material is then carried away over a sharp tear-off edge on the doctor-element at an angle of less than 20°.  In this way a coating of any desired thickness may be applied to a strip of material, more particularly as a coating for a strip of paper.

Abstract: METHOD AND APPARATUS FOR OPTIMIZING SYSTEM OPERATIONAL PARAMETERS           THROUGH AFFINE SCALING     Abstract Method and apparatus for optimizing the operational state of a system employing iterative steps that approximately follow a projective scaling trajectory or an affine scaling trajectory, or curve, in computing from its present state, ?0 to a next state ?1 toward the optimum state. The movement is made in a transformed space where the present (transformed) state of the system is at the center of the space, and the curve approximation is in the form of a power series in the step size.  The process thus develops a sequence of tentative states ?1, ?2, ?n.... It halts when a selected suitable stopping criterion is satisfied, and assigns the most recent tentative state as the optimized operating state of the system.

Abstract: TAMPER INDICATING PACKAGE                  Abstract of the Disclosure A tamper indicating package comprising a one-piece molded closure of plastic which threads onto a container such that when the closure is unthreaded, a tamper-indicating ring becomes separated from the lower end of the closure skirt.  The indicating ring or band is joined to the closure along a weakened frangible line and a flexible stop ring is formed within the band and extends inwardly and upwardly when the closure is applied to a container finish. The container finish has a first radial bead, a second radial bead spaced axially below the first bead, and an intermediate tapered or concave surface between the first radial bead and second radial bead  A further surface extends from the second bead axially downwardly and radially inwardly and the flexible end of the stop ring rests on this surface between the two beads, when the closure is applied.          When the closure is unthreaded to remove it, the free end of the stop ring passes over the second bead into the recess formed by the surface between the two beads and the frangible portion is broken leaving the ring and band in this position.  Upon subsequent reapplication of the closure,  the closure skirt engages the band causing the band to pass over the second bead on the finish so that the band falls away but remains on the container to indicate that the band has been severed.                             -i-

Granted: 1991-08-13
Abstract: OSCILLATION SUPPRESSOR FOR SELF-LEVELING BOOM          ABSTRACT OF THE DISCLOSURE        In a vehicle provided with a boom assembly that  extends  laterally  therefrom  during  use,  a self-leveling  mount  for  said  assembly  employs  a swinging    linkage    having    dampening    devices incorporated  into  the  pivotal  connections  of  the linkage to suppress side-to-side oscillation of the boom.   Each  such device  includes  a  tubular  member arranged on a fore-and-aft axis of the vehicle,  an axle in the member movable with an associated leg of the linkage, a resilient bushing in the member around the axle, and means subjecting the bushing to axial compression to force the bushing radially outwardly and  inwardly  into  frictional  engagement  with  the inner surface of the member and an outer surface of the axle it surrounds.  Compression of the bushing is caused by force against pressure elements in the form of washers that bear against the ends of the bushing, thereby  eliminating  the  need  for oil-filled  shock absorbers or other costly components to suppress boom oscillation.

Abstract: ABSTRACT OF THE DISCLOSURE      A bistable actuating solenoid device having an axially translatable armature which is stable at either a first or a second position   The device employs a solenoid winding wrapped around a bobbin having an internal bore with the armature  disposed  in  the bore    A  permanent  magnet  is located at one end of the bobbin for holding the armature in the first position and a spring urges the armature toward the  second  position   When  it  is  desired to move  the armature from the first to the second position, a current is passed through the winding such that a magnetic field is generated which opposes the field presented by the permanent magnet to allow the armature to move to the second position under the influence of the spring   When it is desired to return the armature to the first position, a current is passed through the winding in a direction which generates a field which combines with that of the permanent magnet to attract the armature to the first position against the biasing  force  of  the  spring    The  armature  thereafter remains in the first position due to the attraction force of the permanent magnet.

Title: Bottle conveying system
Inventor: DIFRANK FRANK J
IPC: B65G47/26
Filed: 1988-08-25
Granted: 1992-09-29
Abstract: ABSTRACT OF DISCLOSURE    Apparatus is described for conveying newly formed, hot bottles from the forming machine to an annealing lehr which is conventionally positioned with its lehr mat or belt running in a direction parallel to the movement of the transfer con-veyor.  The transfer conveyor surface is driven at a first speed as it passes in front of the multiple section glass forming machine.  After passing the machine sections, the conveyor, made of a plurality of horizontal links, has the individual, successive links moved closer together to, in effect, shorten the length of the link belt conveyor.  This shortening is the result of the drive for the link belt conveyor being discontinued just after the belt is engaged from beneath by a magnetic link belt chain driven at a slower speed.  The chain is guided in a first straight line parallel to the machine conveyor direction and then guided through a 90° arc to pass in front of the lehr so the bottles can be transferred from the conveyor surface to the lehr mat with a lehr loader.  The system described above may be doubled so that two conveyors are provided to carry the bottles to the lehr and thus the speed of the conveyors does not need to be as fast and the bottles are more stable during transfer.
