Title: Method and apparatus for making an irregularly shaped drawn tube
Inventor: JOHNSON BRUCE R
IPC: B21D26/045
Filed: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE   Method and apparatus for forming a tubular metal member of a shape and length having an opened end and a closed end into an element which is formed of a different shape and length by forcing and thereby flowing the metal of the tubular member from one mold cavity to another. The apparatus comprises a form mold having an entrance cavity of a shape and length generally corresponding to the tubular member and in which the entire  tubular member  is  initially  located  and  an  exit cavity  of  a different shape and  length in which the flowing metal of  the  tubular metal member is forced to form the element having the shape and length of the exit cavity.  The form mold has an entrance opening in a side wall thereof which is connected to the entrance cavity.  The tubular metal is initially located entirely within the entrance cavity of the form mold, with  the closed end thereof  located adjacent  the exit cavity and  the opened end of  the  tubular metal member being located at the entrance opening to the entrance cavity.  Means are provided for simultaneously applying a mechanical force and a hydraulic force in a first direction to the tubular metal member to thereby flow the metal of the tubular member from  the  entrance  cavity  into  the  exit  cavity  to  form  the  formed element.  The form mold has a passage leading from the exit cavity to a source of hydraulic  fluid which reacts against  the closed end of  the tubular metal member in a second direction in opposition to the hydraulic and mechanical forces applied in the first direction to the tubular metal member  in order  to control  the speed of  the formation of  the formed element.

Title: Method and apparatus for restoring convolution degraded images and signals
Inventor: SUBBARAO MURALIDHARA
IPC: G06T5/20
Filed: 1991-07-02
Abstract: ABSTRACT Apparatus and method are described for restoring convolution degraded signals such as blurred images produced by defocused cameras and moving objects. The degraded signal is first processed by a noise reduction means to reduce noise. Then various derivatives of the degraded signal are computed. Each derivative thus computed is multiplied by a corre-sponding weight parameter to give a weighted derivative. All the weighted derivatives are then summed to obtain a restored signal. The weight parameters themselves are computed based on the moments of the convolution kernel. The apparatus of the present invention comprises a noise reduction means, a weight parameter computation means, a multiplication means, and a summation means. The computations involved in the method of the present invention are local in nature and do not involve computing Fourier transforms. Hence the method and the apparatus of the present invention are efficient and less expensive than conventional methods and apparatuses.
