Title: Line transformer core butt joints - bonded by two plastics adhesives of specified different properties
Inventor: REICHOW WOLFGANG
IPC: H01F3/14
Filed: 1979-07-05
Abstract: Transformer, esp. a line transformer for TV receivers, consists of two U-shaped cores which are assembled to an annular core and are bonded together at the two butt joints. The adhesive for the first butt joint has a long hardening time and a high ultimate strength, independent of temperature and humidity. It is preferably a two-component adhesive with a curing time of 24 hrs., such as 'Araldite' (RTM). The second butt joint is bonded by an adhesive with a short hardening time (2 min.) and an ultimate strength which may have a falling trend in time; this is pref. a cyan-acrylate adhesive such as 'Sicomet' (RTM). This combines the conflicting demands of fast curing time and high long-term strength; it is less expensive than butt strap and screw joints.

Patent DE-3107226-A1 (DE)
Inventor: ZIMMERMANN ADOLF
IPC: F23J15/00
Filed: 1981-02-26
Abstract: In an apparatus for separating suspended particles, such as ash, from stack gas, consisting of a coarse separator, a take-up container for particles removed from suspension in the coarse separator, a fines separator for the partially-cleaned gas output of the coarse separator, and a stack for the cleaned gas output of the fines separator, a new arrangement is disclosed for maintaining the temperature of the dirty stack gas within the apparatus above its dew point so as to prevent the deposition of soot (sooting-up), such arrangement being the construction of the apparatus in such a way that the coarse separator, the fines separator and the outlet stack form an integral structural unit which sits upon the take-up container, which is supported by feet set upon a foundation. In such arrangement, the heat of the hot, suspended ashes deposited in the take-up container is transferred to the take-up container, and thence, to the elements of the integral structural unit. Thus, the heat content of the ash is transferred to the entire apparatus so that the temperature of the stack gas therein is maintained above the dew point.
