Title: Slow-combustion stove with ceramic outer casing, in which different fuels are burned by means of fuel inserts with a high degree of efficiency for the heating of living areas
IPC: F24B1/04
Filed: 1981-02-26
Abstract: The application is based on the inventive concept of increasing the degree of efficiency of conventional stoves, taking into consideration the following objectives:   a) increasing the heating surface, without reducing the living space, by means of convection pipes in and above the combustion area, thereby increasing the heating area, b) heat recovery and lowering of the waste gas temperature by drawing in fresh air and mixing with room air in the area under the cover after mixing through the counter-current channel into the distributor channel inside the back wall. The heating causes an acceleration from the distributor channel into the convection pipes, and as a result the lighter air passes out through the openings in the front tiles without draught air, c) healthy climatic conditions as a result of controlled admission of fresh air, which is heated in counter-current, d) combustion of different fuels in one stove with a high degree of efficiency by means of special fuel inserts which are constructed for a wide variety of fuels.

Patent DE-3120318-A1 (DE)
Title: Circuit arrangement for an integrable amplifier switching device in telephone stations
Inventor: LEISTNER RUDOLF
IPC: H04M1/60
Filed: 1981-05-21
Abstract: The invention relates to an amplifier switching device in telephone stations, where characters generated by contact actuation have a different meaning depending on the actuation sequence. The object of the invention is to produce this amplifier switching device in integrable form, where the actuation of an unlockable key and the respective switching position of a changeover contact initiate a corresponding amplifier activation or de-activation. This is achieved according to the figure in that a setting device (SE) is connected, via a first control input (S), up-stream from a bistable trigger circuit (K) which activates and de-activates the amplifier (V) via a first control output (Q) and which, during the amplifier activation time, with the aid of a relay controller (RST) via a second control output, controls a bistable relay (R) which connects a feed voltage to the circuit arrangement, in that the trigger circuit (K) is connected via a second control input (R) to a resetting device (RE) which can be activated via a changeover contact (Gu) and via a third control input (E) to a comparator device (VGE) which identifies the switching position of the changeover contact (Gu) and the actuation of a key (Ta) and generates a control signal therefrom, and in that the comparator device (VGE) and the resetting device (RE) are interconnected according to the existing signalling to provide a reciprocal blocking facility. This offers the advantage that the switching position of the changeover contact and the subsequent actuation of the key or changing of the switching position after key actuation have different effects. The effect can be produced in any integrated telephone station having an amplifier. <IMAGE>

Title: Self-adhesive mould elements
Inventor: FROMMKNECHT HANS
IPC: A63H33/04
Filed: 1981-06-02
Abstract: Self-adhesive mould elements are equipped with adhesive rods or bristles which serve to provide a frictionally engaged mutual connection which can be released in a non-destructive manner. The design of such items means that it has only been possible to make practical use of them to a limited extent in previous mould elements and in childrens toys in particular. The applicability and the structural possibilities of such a mould element are considerably increased by providing them with relatively long and elastic adhesive rods which are designed and arranged in such a way that they permit any reproduction of the combined structure in all directions. Spherical mould elements are preferred, which are provided with bonding rods on all sides and can therefore be combined to produce a virtually unlimited variety of shapes. The particular length of the bonding rods also means that they can be structured to produce a durable positive and non-positive bonding effect, so that bodies for use in technical modelling and as visual aids in instruction can also be moulded. The exclusive use of plastic as a material means that it can be equipped with a wide range of accessories.

Title: Stowing box for caravans
Inventor: CLAAS PAUL
IPC: B60P3/32
Filed: 1981-10-03
Abstract: In caravans and dormobiles, the problem of a lack of stowing space is solved by a stowing box whose individual walls are detachably connected to one another and to a front frame. The front frame itself has attachment means, preferably fixed-on piping, which corresponds to the floor of the caravan and can be inserted into the weatherstrips running along the longitudinal sides. In this way, a simple and secure connection and support of the easily transportable and easily mountable stowing box is given, in which case the piping can be subsequently locked by the extendable supports of the caravan so that the stowing box cannot be removed by unauthorised persons. <IMAGE>
Patent DE-3142131-A1 (DE)
Title: Fibre-optic light signal
Inventor: HURTIG GUENTHER ING GRAD
IPC: G09F9/305
Filed: 1981-10-23
Abstract: There have been developed for railway and road traffic inter alia fibre-optic light signals in which the respectively visible signal image consists of a multiplicity of optical fibre bundles illuminated from the rear. Illumination of the signal-adjacent observation region outside a prescribed light beam region is mostly abandoned, because the number of optical fibres available overall is restricted, and this restricted number of optical fibres is required for the long-distance projection of the symbol. It is true that the use of diffusing screens provides illumination of the signal-adjacent observation space; however, it also leads to a limitation of the long-distance recognisability of the signal. The invention proposes that the optical fibres available overall for a light signal be combined on the output side to form bundles of different optical fibre density, and that the latter be distributed over the focal surface of the imaging lens (4) in such a way that the bundles of high optical fibre density serve for the long-distance projection and those of lower optical fibre density serve for the formation of scattered light in the near zone of the light signal. <IMAGE>

Title: Auxiliary element for screw connections
Inventor: WIESNER HERMANN
IPC: F16D1/08
Filed: 1982-03-11
Abstract: In the case of screw connections, especially those which are subject to frequent dynamic load changes, as a result of the high surface pressure on the end surfaces of the mutually connected parts and on the thread edges, the problem often arises that said connection can be released only with difficulty, frequently only by destroying one or more parts. The invention provides a remedy for this problem by means of an auxiliary element which can be inserted between the end surfaces of the parts which are to be screwed to one another and can be deformed and/or removed before the release process. The stress relief resulting in this way allows easy releasing and prevents the destruction of individual parts.

Title: Joining piece for linking a wiper blade to a wiper arm
Inventor: EGNER-WALTER BRUNO
IPC: B60S1/40
Filed: 1982-06-18
Abstract: The invention relates to a joining piece having two limbs which are joined together at one end and form with their inner surfaces a receptacle which is open at the edge towards the free ends of the limbs. In the assembled state, this receptacle rests at least partially against more than half the circumference of the outer surface of the connection bolt. Since the inner surface of at least one limb is elastically deformable, it is possible to release the wiper blade from the wiper arm without touching the joining piece by moving the wiper blade in its longitudinal direction. Such a joining piece is suitable for a wiper blade with a single bar supporting structure which has little free space below the connection bolt.
Patent DE-3227523-A1 (DE)
Inventor: CREMER JOSEF DIPL CHEM DR
IPC: C01B25/32
Filed: 1982-07-23
Abstract: The disclosure relates to a process for making calciummonohydrogen phosphate dihydrate with a high degree of whiteness from pure phosphoric acid and naturally occurring calcium carbonates. More particularly, a fine-particulate calcium carbonate is suspended in water and the suspension is mixed at temperatures between 0 DEG  and 60 DEG  C. with phosphoric acid so as to establish a Ca/P-ratio of 0.20 up to 0.57. The phosphoric acid is added in quantities per unit time preventing the resulting mixture from foaming over. Next, solid matter constituents are separated from the mixture, after CO2 has ceased to evolve, with the resultant formation of a clear colorless acid solution. This solution and an aqueous suspension or solution of pure alkali metal and/or alkaline earth metal carbonates and/or hydroxides, are jointly introduced into a reaction zone at a reaction temperature of 20 DEG  to 45 DEG  C. so as to establish a pH-value initially of 2.0 to 5.0 and then, towards the end of the reaction of 6.0 to 8.0. Finally, the reaction product is filtered off, washed out, and dried in known fashion.
