Abstract: A method of manufacturing a metallurgically monolithic integral heated probe for injection molding. An electrical terminal (80) and three portions (90,92,60) of the probe body are made and assembled together with an electrical heating element (72) extending in an aligned bore. The forward portion (90) is made of abrasion resistant high speed steel, while the rest of the probe body is made of hot work tool steel. A removable and reusable filler tube (132) is screwed into a threaded seat (88) in the rear cap portion (60) and a quantity of silver (136) is loaded into it. After a nickel alloy brazing material (131) is applied to the joins, the assembly is heated in a reduced oxygen atmosphere in a vacuum furnace according to a predetermined cycle. The nickel alloy seals all the joins and the silver braze fills all the spaces between the components to provide a metallurgically monolithic integral probe. Using silver which is more conductive and has a lower melting temperature than copper reduces the cycle time and avoids having to heat the assembly into the austenitizing range of the steel body. <IMAGE>

Inventor: SCHULZ GALYN A
IPC: B31F1/07
Filed: 1992-02-03
Abstract: An apparatus for embossing a fibrous web includes a mated pair of resilient and rigid embossing rolls wherein the resilient roll is formed e.g. by laser burning, with recesses adapted to receive protuberances on the rigid male embossing roll when the rolls are placed in contact.  By providing recesses on the resilient roll, the pressure or force required for causing the resilient material, e.g. rubber, to flow around the protuberances can be significantly decreased as compared to conventional rubber to steel embossing.  As a result, wear on the rolls is reduced, and smaller diameter rolls may be utilized, thereby reducing the cost of the embossing equipment.  In addition, since less pressure is required to cause the rubber to flow about the protuberances, roll deflection is not a problem, and an embossed pattern can be imparted having a consistent, high degree of definition across the width of a web.
