Abstract: ABSTRACT      A process and apparatus for manufacturing a polyester container having good clarity and dimensional stability and which can be used in hot-fill food package manufacture and/or in making a container for reheating or heating the contents within.  In particular, this process and apparatus is a deep stretch-forming technique for prepar-ing biaxially oriented, heat set, sealable containers of high molecular weight polyethylene terephthalate.  The process comprises deep drawing a preheated sheet of the polyester 50 into a heated female cavity 34 by means of a male plug 10.  The part is heat set against the female cavity 34, and cooled against the male plug 10 which is used as a constraint.  The part is subsequently removed from the male plug 10.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention provides an efficient and economical means for indexing products from a continuously moving chain conveyor to a stationary position for robotic operations and then returning the product to the moving chain conveyor. Indexing is achieved by a moveable shuttle carriage which is propelled along the axis of a main drive shaft through the engagement of a follower, located beneath the shuttle carriage, with a helical recess in the circumference of the shaft.  Controlled acceleration, deceleration and positioning are accomplished by varying the rotational speed of a uniform helical drive shaft or by the use of a variable helical drive shaft rotated at constant speed.  The shuttle carriage picks up a product carrier by engagement of a drive dog with the carrier to propel the carriage and carrier in unison to an operating station along tracks in parallelism with the axis of the shaft.  Several indexing units may be employed in tandem to provide accumulation of products and to transfer each product back to the moving conveyor after the operation has been performed.

Abstract: ABSTRACT OF THE DISCLOSURE            The  problem  of joining silicon nitride to a  metal  or metal  alloy  is overcome by bonding a  surface  of  the silicon nitride      to a layer of aluminium oxide or an aluminium  silicon  compound  or magnesia  or  magnesium oxide  or mullite,  then bonding that first layer  to  a layer  of  nickel  alumina  before  joining  the  nickel alumina  to  the metal or metal alloy by a  conventional brazing  or  welding process.   This  has  the  further advantage   of   accommodating  the   widely   differing coefficients  of thermal expansion between  the  silicon nitride  and  the  metal by the provision  of  materials between  them which have graded coefficients of  thermal expansion  between  the  two  extreme  coefficients   of thermal  expansion.   The method can be used to  produce pistons  having silicon nitride crown portions joined to aluminium or aluminium alloy piston bodies or to produce gas  turbine  blade assemblies  having  silicon  nitride aerofoils joined to a metal root.

Abstract: ABSTRACT OF THE DISCLOSURE:          Process of making steel by melting sponge iron in an electric arc furnace.  The sponge iron produced by direct reduction is melted in an electric arc furnace, in which a pool of liquid metal is maintained.  To ensure that liquid carbon-containing iron for forming the pool is available in adequate quantities and that the process can be carried out with the highest possible economy, the sponge iron is reacted in an electric arc furnace on a bath of liquid carbon-containing iron which has been produced from sponge iron or from partly reduced ore in an electric reducing furnace.  And, in dependence on the electric load changes which are due to the operation of the electric arc furnace the operation of the electric reducing furnace is so control-led that a virtually constant load on the electric power supply system is maintained.
