Title: Roll embossing of discrete features
Inventor: BALL MELVILLE DOUGLAS
IPC: B44B5/00
Filed: 2005-11-30
Abstract: A cold rolling process for impressing a pattern on a surface of a sheet metal article involves passing the sheet article through a pair of rolls and engaging a patterning feature with isolated areas of a surface of the sheet article, at a localized pressure to plastically deform at least the surface of the sheet article. A rolling pressure is maintained on other areas of the sheet article that is less than the bulk elastic yield strength of the metal. A cold rolling apparatus is also described having a pair of rolls, each with partially cylindrical outer surfaces. The rolls have a gap between the cylindrical parts. One of the rolls has a localized surface region that is displaced relative to the surface of the roll. When the localized region is brought near the other roll, a spacing exists that is narrower than the gap. One of the rolls has a localized patterning feature that aligns with the localized surface region to impress a pattern into the sheet article. The gap allows the rolls to engage opposite surfaces of the sheet article while imparting compression less than a bulk elastic yield strength of the metal.

Title: Improvements in scanning induction hardening
IPC: C21D1/10
Filed: 1989-02-13
Abstract: A scanning induction hardening process in which a steel workpiece is surface hardened by progressively traversing its length with an inductor coil energised by an alternating electric current and immediately thereafter quenching the heated portion of the workpiece straightening of bends in the workpiece being surfaced hardened being controlled during the induction hardening process by monitoring the straightness of the workpiece and utilising information thereby obtained to control the heating and quenching of the workpiece in such a manner that a layer of hardened material of greater thickness is formed on the concave side of any bend in the workpiece such as to produce a straightening moment acting to remove the bend characterised in that the inductor coil is shaped to heat only a portion of the circumference of the workpiece, or shaped to concentrate more heat in one portion of the circumference, and the speed of rotation of the workpiece is varied to allow the concave side of the workpiece to remain in the concentrated heating area longer, and thus, upon quenching, to receive a deeper martensitic layer on this side.

Title: Green cheese handling system
Inventor: BROCKWELL IAN P
IPC: A01J25/12
Filed: 1993-05-07
Abstract: A system for handling of cheese in the green state particularly directed for handling natural cheese types in a manner so that they can be conveniently sub-divided and individually packaged, on the same day of manufacturing, into a variety of finished consumer and cheese market sized portions. The system includes the handling of green cheese immediately as it is formed through the processes of batch or continuous cheese making equipment to provide selected blocks of green cheese. The cheese blocks are immediately handled after forming to eliminate the normally utilized bulk block aging or curing systems. The green cheese blocks are selectively handled and may be placed into temporary bulk block pouches and packaged for future handling or are directed to trimming and cutting devices which will trim and cut the blocks into the consumer, market size units. The aspect of green cheese handling allows immediate recycling of the green cheese material should it, for any reason, not meet consumer, market quality conditions. The entire handling operation and recycling operation insures that the cheese is handled in the green state.
