Abstract: ABSTRACT OF THE DISCLOSURE             A  method  and  apparatus for preparing cast  composite  materials of nonmetallic particles in  a  metallic matrix, wherein particles are mixed into  a  molten  metallic  alloy  to wet the molten metal  to  the  particles,  and  the  particles and metal  are  sheared  past  each  other  to  promote wetting  of the particles by the metal.  The mixing occurs  while  minimizing  the  introduction of gas into   the   mixture,   and  while  minimizing  the retention    of    gas   at   the   particle-liquid interface.      Mixing   is   done   at  a  maximum temperature    whereat  the   particles   do   not substantially  chemically  degrade  in  the molten metal  during the time required for processing, and casting  is done at a temperature sufficiently high that  there  is no solid metal present in the melt. Mixing    is   preferably   accomplished   with   a dispersing  impeller, or a dispersing impeller used with a sweeping impeller.

Title: Method for preserving foodstuffs in cup-shaped containers
Inventor: GRUENE HELMUT
IPC: B65B31/00
Filed: 1987-07-23
Granted: 1992-09-08
Abstract: ABSTRACT           Open-top cup-shaped containers which contain supplies of perishable foodstuffs are transported seriatim past a station where they receive jets of preserving gas which expels air from the unfilled portions of containers, and the containers are then sealed by application of metallic or plastic foils which are bonded or otherwise sealingly secured to washer-like rims surrounding the open tops of the containers.  The foils can be partially applied ahead of the gas introducing station and are thereupon finally sealed in at least one second step, particularly in a chamber wherein the containers advance stepwise downstream of the gas introducing station and wherein the temperature and/or pressure is maintained at a preselected value to promote expulsion of air from the containers prior to the final sealing step.
