Title: Automatically extinguishing candle - has heat removing device near base of wick esp. copper tube water reservoir or nitrogen container
Inventor: STAUDENMAIER ERWIN
IPC: C11C5/00
Filed: 1980-06-24
Abstract: Household fires are prevented from being initiated by candles by designing the candle so that the conditions for maintaining the flame are removed after a certain, accurately predetermined portion of the candle has been consumed. Pref. the wick is embedded in a copper tube within the lower third of the candle, so that when the flame reaches this point the heat necessary for maintaining the combustion temperature is removed from the flame. Instead of a copper tube, a volume of water of approx. 0.5-1.0c is cast into the lower part of the candle so that when the flame reaches this point it is extinguished. A nitrogen-filled plastics container is used instead of the volume of water; when the candle flame reaches this point it burns a hole in the container, nitrogen flows out towards the flame and shields it from oxygen for a sufficient time for the flame to be extinguished.

Title: Motor caravan with two-part lifting roof - has rear roof lowerable to connect with raised front roof to allow driving with luggage area loaded
Inventor: BAUHOF KARL
IPC: B60P3/34
Filed: 1980-09-25
Abstract: The caravan (2) has a two part lifting roof (3). The rear roof (7) raises to form a bedroom (6) while the front roof (10) raises to provide luggage storage space (5). The sides are closed by a bellows type awning (20). The front roof when raised also moves rearwards so that the rear roof can be lowered to connect with it. This forms a gable roof which allows the caravan to be driven for relatively short distances while still loaded in the luggage space, thus making it unnecessary to unload and fold in the roof for every short journey. For long journeys the raisable roof frame forms a luggage rack.
Patent DE-3042154-A1 (DE)
Title: Special adhesive e.g. micro-encapsulated adhesive esp. for bolts - expands during reaction to form tight connection to resist vibration
Inventor: KAUER WERNER DIPL ING
IPC: C09J5/08
Filed: 1980-11-08
Abstract: A special adhesive, e.g. a micro-encapsulated adhesive, is intended for sealing and securing purposes in making joints, for example for locking a nut onto a bolt. The chemical-physical reaction of the adhesive components cause it to expand as it hardens. More specifically the material still remains compressible under external pressure; after a given time the expansion process ceases. The adhesive is particularly intended for bolted connections subject to vibration, for example cylinder head bolts in an automobile, fixing in chemical plant etc.
Patent DE-3102860-A1 (DE)
Title: Device for continuously determining the electrochemical potential of a test medium
Inventor: GRAF PETER
IPC: G01N27/28
Filed: 1981-01-29
Abstract: A test cell (60) comprising a test electrode (62) and a reference electrode (63) and a device for compensating for the pressure of the test medium (11) in a reference medium (61) which is in communication with the reference electrode (63) are provided in a device for continuously determining the electrochemical potential of a test medium (11). For the purpose of rapidly compensating for the test-medium pressure in the reference medium (61) without providing external energy, the compensating device has two pressure chambers (30, 40). The first (30) of these pressure chambers (30, 40) is filled with the test medium (11) and is constantly exposed to the static pressure of the test medium (11). The second (40) of these pressure chambers (30, 40) is filled with the reference medium (61) and is in communication with the reference electrode (63). Both chambers (30, 40) are separated from one another by a flexible membrane (20), with the result that the static pressure of the test medium (11) is transmitted directly to the reference medium (61). The static pressure or overpressure can easily be predetermined by dimensioning a weight (21) so that, even under extreme operating conditions, the medium to be measured can never enter the reference-electrode system. A remarkable feature of the device is an almost delay-free response and it achieves a high accuracy of the potential values determined even with rapidly varying pressure. <IMAGE>

Title: Method of producing sails for sailing boats, in particular surfboards
Inventor: SCOPINICH VITTORIO
IPC: B63H9/06
Filed: 1981-05-18
Abstract: The invention relates to a method of producing sails for sailing boats, in particular surfboards, in which the sail cloth is subjected to such treatment that the desired sail profile is obtained by a one-piece sail-cloth blank being inserted in the stretched state into a press mould, the female mould and the male mould of which correspond to the desired sail profile, and by being pressed under pressure and heat by bringing together the female mould and the male mould in such a way that the thread material from which the sail cloth is made is permanently deformed to form the sail profile. The hitherto necessary cutting-to-size of the individual sheets of which the sail was composed and the sewing-together of this sheet are thereby avoided and a sail is created which is made in one piece which has been given the desired sail profile by the press operation, that is, it has been spatially curved.
