Title: Process for producing sound-insulating plastic window frames and plastic window frame produced by this process
IPC: E06B3/22
Filed: 1981-07-14
Abstract: In order to produce sound-insulating plastic window frames with comparatively high sound-reduction values, first of all a plurality of frame parts are produced as hollow profiles and then push-in parts (4) are introduced into the cavities of the individual frame parts, the external dimensions of said push-in parts corresponding to the internal dimensions of the cavities of the frame parts. In order to position the push-in parts precisely within the cavities of the frame parts, the push-in parts are equipped in their longitudinal direction with weld grooves to which there are assigned weld protrusions formed on the inner wall of the cavities of the frame parts. After introduction of the push-in parts into the cavities of the frame parts the respective push-in part (4) is welded to the frame part (2) in certain areas. The push-in parts are equipped in their interior with sound-insulating means, for example with a sound-absorbing labyrinth (6). All the individual parts of the window frame produced in this manner can be easily produced by the extrusion process. <IMAGE>

Title: Process for the production of fireproof cable and lead bushings
Inventor: VOM BRUCK KARL
IPC: H02G3/22
Filed: 1981-10-06
Abstract: In a process for the production of cable and lead bushings through walls and the like, to form the end faces of the bushing, absorbent, swellable material parts surrounding the cable are inserted into a wall opening and, for swelling, the material parts are brought into contact with a liquid, the intermediate space produced being filled with a casting compound. In order to make the process more simple and to make it quicker to carry out, the invention provides that a low-viscosity casting compound is used, which is of such a nature that the material parts draw the liquid required for swelling from the casting compound, so that on the one hand a sealing takes place and on the other hand the casting compound becomes highly viscous by the extraction of the liquid component, so that flowing out is not possible. <IMAGE>

Title: Trampoline for rescue purposes
Inventor: FRANK HANS-ALBRECHT
IPC: A62B1/22
Filed: 1981-11-25
Abstract: Trampolines are rescue apparatuses which are preferably used by fire brigades to catch persons jumping or falling from a height. The aim and object of the invention consist in offering great protection to persons impacting on the side of the trampoline rescue apparatus and reducing the danger of injury by means of a special design. According to the invention, a square body, tautly inflated with air, consisting of airtight, flexible material is provided at, preferably, three edges of the jumping surface with pneumatically stabilised beads. Good damping without subsequent resilience is achievable by means of built-in overpressure valves in the base body, whereas the beads are connected to the said base body only during filling, by means of air flaps. When a person impacts at the side of the apparatus, the bead lies between the person and the wall of the building and damps the outward-directed force. The person who has jumped can be rescued by the open fourth edge of the jumping surface. Polygonal or circular shapes of the trampoline according to the invention are also possible.

Patent DE-3247033-A1 (DE)
Title: Circuit arrangement with a frequency-dependent attenuation response
Inventor: HERCHNER DIETER ING GRAD
IPC: H03H11/24
Filed: 1982-12-18
Abstract: The invention relates to a circuit arrangement with which different direct-current supply voltages are generated for at least two loads. The first direct-current supply voltage is derived directly from the input voltage, filtering out the alternating voltage component which is superimposed on the direct-current input voltage. The first direct-current supply voltage is consequently reduced in comparison with the direct-current input voltage by an absolute amount. The second direct-current supply voltage is derived from the first direct-current supply voltage, the second part of the circuit, provided for this purpose, containing means which compensate again for the voltage amount by which the first supply voltage was reduced, so that the second direct-current supply voltage is directly proportional to the direct-current input voltage.

Title: Process for the purification of chloride-containing magnesium oxide
Inventor: SCHERZBERG HEINZ DR DIPL ING
IPC: C01F5/10
Filed: 1983-06-27
Abstract: The invention relates to a process for the purification of a chloride-containing magnesium oxide which is produced as the primary product in the thermal cleavage of magnesium chloride and must be further purified in the course of further processing to give pure magnesium oxide or synthetic sintered magnesite. The aim of the invention is to improve the economics, in particular the thermal balance, of the production of magnesium oxide from magnesium chloride. The object of the invention is to develop a process which enables intermediates with much lower water-content to be obtained in the process of washing out impure magnesium oxide with water. According to the invention, this object is achieved in that the washing process including the filtration is carried out in such a manner that a low contact time between MgO and water results, which although it is sufficient to wash out the soluble impurities, does not convert the primarily readily filterable magnesium oxide, which binds little water, into the less readily filterable magnesium hydroxide, which binds considerably more water. In the process according to the invention, the hydration occurs only after the filtration, the water required for the hydration being removed from the water adhering to the filter cake. The invention can be used in the production of pure magnesium oxide.
