Title: Electrically heatable container, such as deep-fat frier, and method for its manufacture
Inventor: SCHANUEL DIETER
IPC: H05B3/50
Filed: 1988-09-07
Abstract: An electrically heatable container (1), such as a deep-fat frier, having an electrical heating resistor (4) attached to the underside of the base (8) is specified, which container is to be visually attractive and nevertheless hygienic to handle. Until now, aluminium containers have been used for this, but they discolour. The container (1) is now made of stainless steel and the heating resistor (4) is soldered on with interposition of an aluminium plate (3) soldered onto the container base (8). A method for manufacturing an electrically heatable container in which an electrical heating resistor is attached to the container base is improved by the fact that the container is manufactured from stainless steel, an aluminium plate is soldered onto its base, the heating resistor is soldered onto the aluminium plate and the container is cleaned and polished, the soldering-on of the heating resistor being carried out before the cleaning and polishing. <IMAGE>

Title: Apparatus for producing plastic containers
Inventor: ZONDLER EBERHARD
IPC: B29C65/78
Filed: 1989-03-29
Abstract: Large plastic containers are fitted together such that surfaces adjoining one another at an angle are produced, a weld then being introduced into these surfaces by means of a welding extruder. These welds are distinguished by high strength, but not by consistent quality. The invention provides an apparatus in which the welding extruder (7) is arranged next to a worktable (1) by means of a slide (6) on a slide rest (3) which can be adjusted in height. The worktable (1) is movable with respect to the slide rest (3) in such a way that the welding shoe (24) of the extruder describes along the plastic parts (21,22) to be welded together a path which the weld is intended to follow. The apparatus therefore permits the automatic creation of welds between plastic parts using a welding extruder (7) and obtaining consistent good quality. Production of plastic containers.
