Title: Air gap switch assembly
Inventor: SPIRA JOEL S
IPC: H01H15/10
Filed: 1986-10-28
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE          An air gap switch assembly with a status indicator that prominently indicates when the switch is in the OFF position and disappears from view when, the switch is in the ON position.  The status indicator is located on the control lever for the switch, which is formed of a clear material and is difficult to see.  The control lever is moveable relative to the housing of the assembly so that when the control lever is in the ON position, the portion of the lever on which the status indicator is located is hidden from view by the housing of the assembly.  When the control lever is moved to the OFF position, the portion of the lever on which the stay tus indicator is located is exposed, thereby providing an indication that the switch is in the OFF position.  The switch is formed of two contacts which are biased togeth-er in electrical contact by an elongated flat metal strip.  The control lever is coupled to a cam.  When the control lever is moved to the OFF position, the cam abuts against the metal strip, forcing the strip to move in a direction opposite to its bias, thereby separating the two contacts and breaking electrical contact.

Title: Turbine blade attachment

Granted: 1992-10-20
Abstract: ABSTRACT    A structure  for  the root portion  of  a  turbine blade  and  for  the  attachment  grooves  on  a  turbine rotor  in  conjunction  with  blades  having  integral shrouds and platforms as well as blades which are not attached to one another,  blades which are joined by nonintegral  shrouds  and blades which do not include platforms.  The  invention  is applicable to straight side entry blade roots and rotor grooves as well as curved  side  entry blades  and  curved  rotor  grooves. The invention results in reduced stress levels in the blade  attachment  structure  by  decreasing  the  land widths and  increasing  the fillet  radii of curvature associated with each tang on a turbine blade root.  In addition,   the   fillet   radii   of   curvature   are individually dimensioned to more uniformly distribute stress levels among blade root tangs.   The reduction in  land  widths  is  accomplished  by  increasing  land contact stresses for a given blade design.

Title: Apparatus for controlling a switching amplifier

IPC: H04B3/58
Filed: 1988-06-09
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE         An  apparatus  for  controlling the  output  of  a switching  amplifier  includes  a  signal  dividing  circuit which generates a delayed replica of the carrier signal and a doubled signal having twice the carrier frequency.  The doubled signal is effective for establishing a second time delayed signal relative to the first time delayed signal. The first and second time delayed signals are logically operated on so that a three state output representing the carrier signal is attained.  A summing amplifier utilizes the two time delayed signals to generate this three state output  whereby  if  the  two  time  delayed  signals  are out-of-phase,  a  zero voltage  is  connected to the drive portion of the switching amplifier thereby  limiting the output of the switching amplifier.

Abstract: Abstract of the Disclosure In a method of examining the states of alignment of glass fibers in a pair of ribbon fiber cables by observ-ing their images obtained in two directions, a reflect-ing mirror is located adjacent to glass fibers of a pair of ribbon fiber cables.  Illuminating light is intro-duced into the glass fibers of the fiber cabes in a direction different from the normal direction of a plane formed by the glass fibers, and an image formed by the illuminating light which is reflected by the reflecting mirror and then passed through the glass fibers and another image formed by the illuminating light which is passed through the glass fibers and then reflected by the reflecting mirror are observed.  According to the examining method, the optical axes of two images obtain-ed on the light receiving side can be made parallel to each other to keep the two images extremely near to each other.  Therefore, the distance along which the pickup system must be moved can be made short.  This makes the system small-sized and the image processing time short.          In addition, the objective used in the pickup system, may have a low magnification.  Further, all of the glass fibers can be observed once on a screen and the adjust-ment of focus relative to the glass fibers may be con-ducted one time when they are observed in each of two directions.  Furthermore, their shift from that axis along which they should be aligned can be detected with a higher accuracy.
