Abstract: A rod-shaped heating element with a tubular carrier element attached to a cylindrical carrier ring and to the rod-shaped heating element using a magnetic forming process, the carrier ring and the rod-shaped heating element being within the tubular carrier element with the outer circumferential surface of the carrier ring contacting the inner circumferential surface of the tubular carrier element. As a result of the parts having been joined by magnetic forming, they are in a plastically deformed state which is free of thermal treatment effects and scuffing.
Abstract: A carbon heating element having an arbitrary specific resistance and an arbitrary shape which are arbitrary necessary as a heating element, and a method of producing the same. The carbon heating element is obtained by uniformly dispersing one or at least two metal or metalloid compounds into a composition having shapability and showing a high yield of a carbon residue after firing, shaping the dispersed material-containing mixture thus obtained, and firing the shaped material under a nonoxidizing atmosphere.
Abstract: Functional elements, particularly PTC heating elements, are braced in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one anther and flat sides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. This makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.

One end face of the rod member has a same plane with a main surface of the plate member, the conductive layer has a heater pattern formed on the main surface of the plate member, and the rod members are electrically insulated not to be short-circuited to each other in the opposite main surface.
Abstract: A spatter guard for covering food in an oven. The guard includes: a first shell configured to cover food, having: a first semi-hemispherical barrier member with a plurality of apertures therein. Additionally, there is a second shell is pivotally coupled to the first shell to substantially form a hemispherical barrier and an array of substantially parallel semi-hemispherical barriers. The array includes a second semi-hemispherical barrier member with a plurality of apertures therein. Moreover, the first shell has a plurality of protrusions extending downwardly from a bottom of the first hemispherical barrier member to space the first shell from a surface. Further, there is a flange that extends outwardly from a bottom of the first hemispherical barrier member. Further, the second shell has a protrusion extending outwardly therefrom and is configured to be used as a handle for actuating the second shell between the first and second positions.
Abstract: A heating device includes a warming member, a battery set, and a control mechanism; the warming member consists of a sheaf of highly resistant filaments, and several spaced-apart conductive wires, which are positioned among, wrapped in, and connected in series to the sheaf of highly resistant filaments; front and rearmost ones of the conductive wires are connected to a battery set, and a control mechanism is connected to the battery set for controlling electric current provided by the battery set; the highly resistant filaments will serve as warming portions of the warming member; the warming portions of the warming member are arranged on inner lateral sides of front portions of finger portions of a glove such that when one wears the glove, the warming portions will be on two lateral sides of first and second sections of the wearer's fingers.
Abstract: A process for manufacturing a plastic pane provided with embedded electrical conductors, in particular a window pane, in which the conductors are joined to a surface of a plastic sheet that subsequently receives another layer of plastic by injection molding from the rear for the purpose of forming a pane body.
