Patent ES-467085-A1 (ES)
Title: Temperature resistant abrasive compact and method for making same
IPC: B22F3/24
Filed: 1978-02-17
Abstract: A tool component, in particular a cutting insert, essentially consists of self-bonded abrasive particles and a network of mutually communicating, dispersely distributed pores. This tool component is made by directly bonding a mass of abrasive particles to one another to give a self-bonded object, using a sinter aid material at high pressures and temperatures. The object formed under the action of the high pressures and temperatures contains self-bonded particles, i.e. particles directly bonded to one another, and is penetrated by the sinter aid material, for example cobalt or cobalt alloys. The sinter aid material is then removed, for example by immersing the object into aqua regia. It has been found that, by removal of essentially all the sinter aid material, an abrasive particle object is obtained which shows a substantially improved resistance to thermal decomposition at high temperatures.

Title: Automatic alignment adjustment of irradiation horn - during curing of continuous profiles, to suit exposure of profiles of differing widths
IPC: B29C71/04
Filed: 1981-09-04
Abstract: Appts. involving irradiation via a trapezoidal horn of a continuous profile travelling a multi-loop path around a pair of parallel rolls has the horn mounted obliquely relative to the loop path. The angular deflection of the horn is adjustable (automatically) so that the projected width of the horn corresponds to the cumulative width of the parallel loops of the running profile travelling side by side. Pref. the width of the individual and collective loops of a particular running profile can be matched by the setting of a multitoothed guide supported by a multiple scissors-action mechanism. Adjustment of the pitch of the scissors elements pref. alsu automatically trims the angle of inclination of the horn to match the overall loop profile path. Applicable to e.g. hoses of crosslinkable rubber or plastics materials. Use of multiple loops extends the effective exposure time for a profile to minimise the size of the irradiation zone.
