Patent DE-3604533-A1 (DE)
Title: Closed-loop control circuit with electrically powered, heat-radiating correcting device for the transverse profile correction of webs of material, in particular webs of paper, cardboard, fabric or plastic
Inventor: WANKE WILHELM DIPL ING
IPC: D21F7/06
Filed: 1986-02-13
Abstract: An installation for producing and/or upgrading a running web of material, in particular a web of paper, cardboard, fabric or plastic, is equipped with one or more roll presses for dewatering or calibrating and/or smoothing the running web of material on the principle of web compression. In this installation there is also installed at least one closed-loop control circuit which comprises not only measured-value pick-ups, preferably traversing, and a computer and control-pulse generator unit, as main components, but also, as a further main component, an electrically powered, heat-radiating correcting device for correction of the transverse profile of the running web of material. This electrically powered, heat-radiating correcting device functionally comprises individual heating elements which act as thermal radiators, are subdivided into zones over the width of the web of material and are directed with varying intensity at one or more metal rolls of the roll press(es) and, as a result, a correction of the transverse profile of the running web of material is brought about by varyingly intense compression of the web of material. The latter is a consequence of zonally varied diameter of the metal roll(s) by heating caused by heat transmitted by thermal radiation.

Title: Device for forming chemically produced permanent waves in hair
Inventor: KOEHLER KLAUS
IPC: A45D2/38
Filed: 1986-03-01
Abstract: The device for forming hair in waves on the scalp comprises a lower part, which is bent in an undulating manner and is made of a flat material, and at least one upper part which is linked pivotably to said lower part and has parallel profiles which correspond in their spacing to the wave troughs and can be inserted in the wave troughs of the lower part. It is thus possible for the first time to give the hair volume directly in the vicinity of the scalp and, by selecting different wave shapes, a different degree of waving can be achieved, seen over the length of the hair. In the case of conventional hair curlers, there is the disadvantage that, when the hair curler is removed, the hair becomes entangled, thus resulting in curls springing back. With the present invention, this is avoided since winding of the hair is not included.

Patent DE-3640644-A1 (DE)
Title: Liquid candles
Inventor: ERLEI JOHANN
IPC: C11C5/00
Filed: 1986-11-28
Abstract: A liquid candle is described which is made of wax or a similar material, can release and evaporate liquid and can thus contribute to air improvement and can release specific scents if fragrances are added to the liquid. The candle possesses hollow spaces which are full of liquid. During burning of the candle, the liquid evaporates from the hollow spaces of the candle, so that fragrances are released; on the one hand the scents emerge with the vapour, while on the other hand the fragrances remain trapped in the hot, liquid wax during the heating and evaporation process and are burnt together with the wax. To what extent fragrance liberation occurs, by emergence of the fragrance together with the vapour from the holes or by burning of the fragrance, depends on the liquid, the fragrances and the additives. In the case of oily liquid, which is to a greater or lesser extent co-burnt, the evaporation, and possibly also the fragrance liberation, occurs more during burning. Liquid holes which are intended to prevent the candle burning hollow are only appropriate if a corresponding minimum burning duration is constantly maintained, that is to say they always have to be completely occupied.

Title: Receiving set for broadcast signals with an additional information contained therein (RDS)
Inventor: EINSEL ROBERT DIPL ING
IPC: H04H20/22
Filed: 1987-06-05
Abstract: This additional information comprises a list of alternative frequencies at which the same programme signal can be received. From the list of alternative frequencies, the receiving set is automatically tuned to the frequency which offers the best possible reception, that is to say the greatest field strength, after a programme signal has been set. Since a transmitter set with the greatest field strength tends to distortions of the AF signal under certain conditions, means are provided by means of which a transmitter which exhibits no or only little distortions in the AF signal can be set from the list of alternative frequencies.
Patent DE-3718954-A1 (DE)
Title: Propeller arrangement, in particular for ship propulsion plants
Inventor: GARTMANN UWE
IPC: F04D29/047
Filed: 1987-06-05
Abstract: Conventional propellers are borne on a hub bearing in their centre. The axial forces acting on the blade tips (3) in particular subject the blades (7) to a large bending moment. Therefore, the blades have to be of very massive construction, which however increases the stresses on the propeller due to centrifugal forces. So the size of such propellers is limited. Furthermore, the cost of the materials for manufacturing conventional propellers is comparatively high. In order to overcome these disadvantages, it is proposed that a propeller (2) equipped with an outer ring (4) be mounted, together with this outer ring (4), in a housing (5), so that a hub bearing can be dispensed with. The axial bending moments acting on the blades (7) of the propeller (2) are reduced, so the blades (7) can be made lighter. The centrifugal forces thus reduced also make larger propeller diameters possible than in the current state of the art. The propeller arrangement (1) can be utilised for ship propulsion and wind generators. <IMAGE>

Patent DE-3735265-A1 (DE)
Title: Cooking appliance
Inventor: SCHREDER FELIX
IPC: F24C15/10
Filed: 1987-10-17
Abstract: In a cooking appliance (1) with at least one heating unit (2, 3) in the form of an electric cooking plate, the latter has two heating-element units in the form of four identical heating resistors (8, 9, 10, 11) which can be connected, via temperature-dependently switched contacts of a manually actuable switching device (24) designed as an adjustable controller, in such a way to the three phase connections of a three-phase power source that the two heating-element units are connected, in the one switching position, on the one hand to a common phase connection and on the other hand separately to the two remaining phases and thereby produce a maximum power, whereas in the other switching position they are connected in series and then, as no-load or continued-cooking power, can only produce about one quarter of the maximum power. As a result, while retaining an extremely simple arrangement and a robust design it is possible to achieve a heating-up which has a very rapid response, is optionally protected against overheating by means of additional temperature limiters, with a favourable no-load power. <IMAGE>

Patent DE-3739633-A1 (DE)
IPC: E04G17/04
Filed: 1987-11-23
Abstract: A connecting element is provided for connecting together adjacent shuttering panels of the kind in which reinforcement strips with rows of holes provided therein are arranged at the edges of the shuttering panels and are dipsosed perpendicular thereto. The connecting element consists essentially of a curved lever arm (13) which tapers from a spigot part (17) to an end surface (18). The spigot part (17) adjoins a handle portion of the connecting element at a flange (16') defining an abutment edge (16). The handle portion is curved in essentially U-shaped manner and has a support surface (20) at the inside of its limb connected to the spigot portion (17). In operation the engagement end (18) of the lever arm is first introduced through two aligned holes in the adjacent reinforcement strips of two adjacent shuttering panels and the connecting element is then rotated about the abutment edge (16) so as to cause the spigot part (17) to enter into the two aligned bores. During this the lever arm clamps the two reinforcement strips together. In the engaged position shown in FIG. 2 the support surface (20) contacts one side of one of the connecting strips and the engagement surface (18) contacts the opposite side of the other reinforcement strip. The U-shaped handle of the connecting element has been pivoted downwardly so that the abutment end (12') thereof engages against the same side of the reinforcement strip (15') as the engagement surface (18). In this position the connecting element is reliably locked in place and the shuttering panels are reliably connected together.

Title: Circuit arrangement for forming the average value of periodically occurring measurement signals
Inventor: FUCHS MANFRED HEINRICH DR
IPC: G01R19/25
Filed: 1987-12-04
Abstract: The invention relates to a circuit arrangement for forming the average value of periodically occurring measurement signals. From each measurement signed, an analogue-digital converter (8) converts a plurality of measured values determined at predeterminable time interpolation (sampling) points into digital measured values. An adder (10) successively adds the digital measured values determined by the analogue-digital converter at one time interpolation point. The sum value is entered after each addition into a main memory (11), which contains different memory areas assigned in each case to one time interpolation point. After the addition of a measured value determined at one time interpolation point to the sum value assigned to this time interpolation point, the new sum value is temporarily stored in an intermediate memory (12) and then entered into the memory area of the main memory assigned to this time interpolation point. A calculation circuit (16) calculates the average value at one time interpolation point after the occurrence of a specific number of measurement signals. <IMAGE>
