Abstract: FRAGILE FOOD PRODUCT PACKAGE                 ABSTRACT OF THE DISCLOSURE     A food product package is disclosed for packing a plurality of fragile shells or bowls composed of a consumable and digestible material consisting of a circular base joining in a continuous circular sidewall having a plurality of evenly spaced semicircular convolutions wherein each convolution is of the same diameter to provide combined or over-all strength.          The shell or bowl composition presents a textured exterior surface visually indicative of an edible product.  The textured surface is characterized as being granular having a wall thickness and cross-section which is brittle and capable of being broken apart for ready consumption.  The plurality of shells or bowls are nested together in a stack confined between opposing inner surfaces of a U-shaped, load carrying protective form captured in a unitary package by a wrap of plastic film.  The protective form includes elongated sidewalls projecting from opposite ends of a base on which the stack rests.  The sidewalls are of greater length than the height of the stack so that terminating end portions extend beyond the stack height in position to receive and absorb impact loads and shocks to the exclusion of the stack.

Title: Containment valve that allows contamination free transfer
Inventor: BANDY MICHAEL J
IPC: F16L37/30
Filed: 1993-01-28
Abstract: ABSTRACT OF THE DISCLOSURE     A containment valve with two butterfly valves at the juncture of a first port and a second port with the two valves pivoting on a common transverse axis.  The ports may be coupled and uncoupled between a coupled mode and an uncoupled mode.  In the uncoupled mode one butterfly valve body locks the first port shut and the other butterfly valve body locks the second port shut to isolate the contents of the ports, such as chemical dust.  Each butterfly valve body has a circumferentially moveable annular locking ring moveable between a first position and a second position.  In one position the locking ring locks the butterfly valve body shut when the ports are in an uncoupled mode.  In the other position the locking rings hold the two ports in the coupled mode.  A spring biased pin lock prevents inadvertent rotation of the annular locking ring.  Annular ribs and grooves are provided on the mating faces of the butterfly valve bodies. The ports are hermaphroditic about both the X-axis and the Y-axis.

Inventor: BUTTRAM JONATHAN D
IPC: G01N29/04
Filed: 1993-09-15
Abstract: The presence of a crack in a material and the orientation of the crack is determined by placing a transducer  on  the  surface  of  the  material for propagating a shear wave for reflection off of the back wall of the material. The reflected signal is evaluated such that no signal or a weak signal indicates the presence of a crack.  The transducer is then held in place and rotated while propagating a shear wave in order to determine the orientation of the crack.  The reflected shear wave is then evaluated in the same manner.
