Patent DE-3141685-A1 (DE)
Title: Safety lamp socket
Inventor: GUENTHER HORST
IPC: H01J5/50
Filed: 1981-10-21
Abstract: In the invention of the safety lamp socket, the research was based on technical safety and economical aspects. Known lamp sockets, which are protected against being touched, are expensive. In this design, the built-in switch (6) is operated by the pressure on the foot contact (4) when the lamp is screwed in, which switch closes the circuit. The installation of the switch (6) results in a small cost outlay in comparison with commercially available lamp sockets. If, in addition, the normally-closed contact (8) is connected to the resistor (5) as a 2nd stage of the safety function, an electrical accident is impossible. In addition, there is no intermittent contact if the lamp is not screwed in sufficiently. This technique can be used for lamp sockets with a bayonet fitting and with a tubular lamp fitting. <IMAGE>

Title: Device for the mutual sealing of plate-like elements on buildings, in particular roofing elements
Inventor: KORNBERGER OTTO
IPC: E04D3/366
Filed: 1981-11-16
Abstract: In known sealings of plate-like elements, in particular roofing elements on buildings, there is a danger of them leaking as a result, for example, of thermally induced shifts or displacements. Moreover, it has been difficult hitherto to exchange such plate-like elements simply and quickly without renewing the sealings. To overcome these deficiencies, provision is made for a trough-shaped section (21) to be provided at the outer edges of the plate-like elements or roofing elements (14) in the region of their upper edges, which section runs parallel to the edges and in which is arranged in each case a sealing strip (22), and furthermore for a covering rail (28) with angled legs (29) to be provided for engagement into the trough-shaped sections (21) of in each case two neighbouring roofing elements (14), which legs are intended for pressing the sealing strips (22) by means of screws (30), which sealing strips are to be clamped between the covering rail (28) and the undersides of neighbouring roofing elements (14). The invention is used mainly in the mutual sealing of plate-like roofing elements which are supported at their corners via threaded bolts on a three-dimensional framework. <IMAGE>

Filed: 1982-02-17
Abstract: The burner for pulverulent, gaseous and/or liquid fuels has an ignition chamber (20) with a wall (8) which opens out and having the rotation symmetry, as well as an exhaust pipe (17, 17') connected thereto. At the center of the chamber wall, there is arranged the inlet of a pipe (1) for the admission of a fuel jet (A) as well as an air supply (50) surrounding said inlet, for the admission of a vortex of combustion air which produces inside the ignition chamber a hot recirculation stream (B) mixing the fuel jet and heating the latter at the ignition temperature. The air quantity of the vortex supplied to the ignition chamber is only a portion of the total combustion air required. In the area between the chamber wall and the exhaust pipe there is provided a second air admission pipe (60) through which another portion of the combustion air (C) may be introduced in the ignition chamber, said portion being totally or partially mixed with the fuel jet. The sum of the combustion air portions participating within the ignition chamber to the mixture with the fuel jet (and hence to the ignition and initiation of the combustion) is adjusted so as not to exceed 50 % of the total combustion air required. By conjugating all those measures, there is provided a burner particularly appropriate for the production of heat for industrial process and further having at intermediary and variable power rates a stable ignition producing a flame with an elongate and thin form in the combustion chamber and thus with a low radial deflection of particles.
