Title: Multi-sectioned mattress for adjustable beds - has two-part head section for individual displacement irrespective of remaining bed sections
Inventor: HUESSLER HERMANN
IPC: A47C19/00
Filed: 1980-05-02
Abstract: The mattress frame comprises several interlinked parts. The head part itself can be moved relative to the centre part and has a further movable area which can be raised relative to the remaining plane of the head part. The raisable area can be followed by a lowerable area which provides free space for the shoulders of the user.

Abstract: A process for the preparation of electrically conductive polymers by polymerizing acenaphthylene, N-vinyl-heterocyclics, eg. N-vinylcarbazole or N-vinylpyridine, or N,N-divinylaniline at from -80 DEG  to +100 DEG  C. in the presence of a cationtic catalyst, wherein from 1 to 50 percent by weight of an oxidizing Lewis acid, preferably FeCl3, FeBr3, SbCl5, SbF5, AsF5 or CF3-SO3H, or a combination of AlCl3 or TiCl4 with the said compounds or with CrO3 or OsO4 is used as the catalyst. In a preferred embodiment of the process, thin films of the monomers to be polymerized, applied to glass or to a polymeric base, preferably to a plastic film, are treated with gaseous SbCl5, SbF5 or AsF5. The conductive polymers obtained can be used in the electrical industry for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches, as well as for the antistatic treatment of plastics.

Title: Staircase lighting time delay circuit - uses relay and electronic time with pushbutton operated override to save electricity
Inventor: ROSER ROLAND
IPC: G04F1/00
Filed: 1980-07-05
Abstract: The time delay circuit for switching off staircase lighting on several floors, uses a relay (Re1) for the switching off operation, which can be overridden by operating a push button (Dr) for a second time. This ensures that the lights (L) are switched off sooner, to save electricity. The push button bring into operation a transistor (T.) in series with a capacitor (C2) and diode (d4) which excite the relay coil with a pulse of about the same time duration to override the relay. In series with the relay is a thyristor (Thy) connected to the capacitor (C2). An integrated circuit (JC) is used to control the time during which the relay maintains current to the lights. This forms an oscillatory circuit with further components (R8, R7,C4,P) to obtain a frequency for a divider which provides a lower frequency signal.

Title: Mangle for the smoothing of damp laundry articles
Inventor: KREINBERG MANFRED
IPC: D06F65/10
Filed: 1981-07-18
Abstract: By means of a mangle, especially damp laundry articles in the form of flat laundry are smoothed, these at the same time being dried. For this purpose, the mangle has rotatably mounted wound rollers in the form of perforated hollow cylinders connected to a suction device and fixed work surfaces in the form of bowls which can be brought into contact with these hollow cylinders and which are heated by high-pressure steam. For the purpose of saving energy, the hot spent air occurring inside the rollers is used for heating a rotatably mounted hollow cylinder (18) which precedes the rollers in the working direction and which serves for the predrying of the laundry articles by the contact method. To improve the energy saving and the drying effect, provision is made for subjecting the laundry articles bearing on the hollow cylinder to fresh air heated in a heat exchanger (73). The heat exchanger is heated by means of the condensate occurring in the bowls. The laundry articles bearing on the hollow-cylinder wall are subjected to the heated fresh air by means of distributor pipes (80) arranged above and at a distance from the hollow cylinder. <IMAGE>

Title: Pulse filter
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: H02P23/24
Filed: 1981-12-22
Abstract: The invention relates to a pulse filter for optionally selecting two switching paths, particularly for a phase angle control circuit. The invention consists in that two output stages are connected to the input connection of the pulse filter via a first logic, these output stages being mutually interlocked via the logic in such a manner that the emission of a pulse by one output stage at the same time prevents the emission of a pulse by the other output stage. Furthermore, an input connection for a selection signal is provided by means of which the switching path to be driven is determined. The input connection for this selection signal is connected via a second logic to inputs of the first logic, this second logic preventing, by means of a logical combination with the outputs of the output stages, a switch-over from one switching path to the other switching path from being able to occur during a current pulse emission by one output stage.
