Granted: 1991-10-22
Abstract: ABSTRACT                  "RETORTABLE PACKAGES"            A retortable, hydraulically solid, sealed package (10) containing a liquid or semi-liquid food product (24) comprises a thermoplastics container (12) formed by a thermo-forming process and a heat-shrinkable thermoplastics closure diaphragm (20).  The closure diaphragm is heat-sealed to a rim (18) of the container after the headspace above the product has been evacuated, and is subsequently subjected to external pressure so as to be non-elastically stretched and made to lie wholly in contact with the enclosed product.  When retorted (e.g. for sterilisation) the package suffers no visible deformation of the container (12), despite the considerable volume shrinkage of the container which may occur.  The loss of volume caused by this volume shrinkage is accommodated by a reduction in the concavity of the diaphragm (20) caused by a corresponding heat-induced shrinkage of the diaphragm material.  The diaphragm continues to exhibit a pleasing, smooth or smoothly curving surface, and the retorted package has a consumer-acceptable appearance.

Title: Method of controlling variation of density of images in 3-d pictures
Inventor: WAH LO ALLEN K
IPC: G03B35/00
Filed: 1988-06-03
Granted: 1995-04-11
Abstract: Three-dimensional photographs produced with image bands of substantially equal density across the field of the lenticule  are  produced  by increasing  the  intensity  of exposure of the image bands near the edges of the lenticule in  relation  to  the  central  image  bands.    This  is accomplished by varying the duration of each exposure,  or using a neutral density filter, a neutral density iris, a metallic iris with a multiple number of apertures,  or by controlling  the  lamps  in  a  multiple  lamp  housing.   In addition,  three-dimensional photographs are produced by a multiple number of successive exposures of short duration through the lenticules of the lenticular print film while the angle of projection of the enlarging lens is constantly changing.   Exposure  is  made  for  a  duration  while  the relative movement of the enlarging lens with respect to the lenticular print film is less than one-tenth of the aperture of the enlarging lens.

Title: Portable infrared imaging apparatus
Inventor: CRALL RICHARD F
IPC: H04N3/09
Filed: 1988-08-04
Granted: 1991-09-24
Abstract: Abstract of the Disclosure Manually portable apparatus enabling high-resolution, two-dimensional infrared imaging of remote, non-contacting targets is described.  An on-axis optical subsystem consists of a single, single-faceted planar scanning mirror that is reciprocable by stepper motors about two orthogonal axes.          Oriented at approximately 45° relative to the mirror's line-of-sight axis to a target, the scanning mirror reflects infrared energy incident thereon toward a spherical converging mirror, which may be manually focused to change the distance between it and a single-element, non-cryogenically cooled, heat-sensitive detector located behind the scanning mirror.  An ADC, a microprocessor and a motor control circuit provide means for imaging the target by sampling the serial, conditioned output of the detector in timed relation to the angular positions of the stepper motors, and transforming energy density data to temperature data in a two-dimensional, pixel array.  Integral display means are provided, by which a colorable infrared image may be viewed.  In a proposed modification, a parabolic, rather than spherical, converging mirror is used.  In another proposed modification, the detector interposes the scanning mirror and the converging mirror, insubstantially occluding the infrared enegy reflected by the former.
