Filed: 1982-07-10
Abstract: The invention relates to a heating boiler with a burner, with a hot water boiler arranged at the top in the boiler water space and flooded with boiler water, and with boiler connections for heating delivery and return flow ducts. It is provided according to the invention that the boiler connection for the heating delivery duct is arranged in the top boiler region, and that the sensor of a thermostat, which acts on the operation of the burner and on the boiler water discharge through the heating delivery duct is seated in the boiler. The advantage derived from this is that in boilers of the kind mentioned at the beginning, with so-called gravity boilers, the advantages of a priority circuit can be utilised.
Patent DE-3225926-A1 (DE)
Title: Apparatus for utilisation of the waste heat from combustion gases, with auxiliary ventilator as a draught intensifier, and also reheating to avoid stack sooting
Inventor: MAROTZKE HORST
IPC: F28D21/00
Filed: 1982-07-10
Abstract: The apparatus serves to improve utilisation of combustion/exhaust gases by heat withdrawal and simultaneous heat transfer to another medium. Thus, in the case of heating units, to the heating circulation water. The apparatus is mounted on the gas side between the heating boiler and the exhaust gas stack and on the water side between the heating return and the boiler return. The degree of cooling of the exhaust gases and/or the waste heat utilisation are characterised by the exhaust gas temperature and heating return temperature on the one hand, and also by the structure of the apparatus on the other hand. The purpose and object of the apparatus are to decrease the exhaust gas temperatures to the dew point of water when heating oil is burnt - to undershoot the dew point of water when gas is burnt - and then to reheat the exhaust gases by about 15 to 20 DEG C in the interior of the apparatus. By this means a hazard-free fuel utilisation with heating oil EL up to about 98% and with natural gas or liquid gas of >/= 100% is achieved without the risk of stack sooting occurring which is otherwise conventional in exhaust heat recovery apparatuses. A small auxiliary ventilator with an ejector is responsible for overcoming the apparatus resistance, so that fault-free operation - independent of the outside air temperature - is ensured. An exhaust gas/bypass flap mounted on the apparatus head thermally isolates the heating boiler and apparatus from the chimney when the burner is shut down and thus prevents the otherwise conventional internal boiler losses as a result of air passage - and simultaneously prevents, by releasing the bypass opening, a cooling of the stack unit, by continuously passing warm heating space air through the chimney. Widely spread trials have shown that the installation of such an apparatus achieves a fuel saving between 18 and 33%. The amortisation times are between 2 and 3 years.

Title: Device and method for clamping two pipes together
Inventor: SASSAK FRANK
IPC: B21D39/04
Filed: 1982-07-13
Abstract: A pipe clamp for the attachment of the annular overlap of two pipes which are joined together and engage in one another contains an annular body which rests in a flush and concentric manner over the pipes and is pushed together or compressed thereon. The annular body is blocked mechanically by the outer pipe, and the pipes are mechanically connected to one another in the form of an annulus and are sealed through 360 DEG . The method for blocking and sealing two telescopic pipes includes the joining together of an annular body around the pipes at their overlap, and the annular pulling together or compression of the annular body on the outer pipe. The annular body deforms both pipes, which form concentric annular channels and a fold in the outer pipe, which fold is located in the channel of the inner pipe. The annular body is mechanically blocked by means of the outer pipe.

Patent DE-3231916-A1 (DE)
Title: Feed device for mineral fertilisers
Inventor: JAESCHKE HANS-JUERGEN DR
IPC: B65G65/42
Filed: 1982-08-27
Abstract: The invention relates to a feed device for mineral fertilisers on fertiliser spreaders for use in agriculture. A disadvantage hitherto has been the irregular feed of a fertiliser from the container to the application members, this being caused by the breakaway of the fertiliser stream at the throw-off point from the conveyor band. According to the invention, there is arranged transversely above the throw-off point (8) in the fertiliser stream (3) a guide plate (11) which divides the fertiliser stream (3) into an upper and a lower part stream. The lower fertiliser stream consequently no longer breaks away, and the upper fertiliser stream likewise falls back continuously on to the lower part stream by way of a serrated rear edge of the guide plate (11). This ensures a uniform feed of mineral fertiliser to the application members. <IMAGE>

Title: Dental finger cap or glove
Inventor: FINKE ANDREAS H DR
IPC: A61C15/00
Filed: 1982-08-31
Abstract: The dental finger cap is an oral-hygienic aid for care of teeth and gums, especially in the prophylaxis of disorders of the periodontium and in the case of periodontopathies, loosening of teeth and exposed tooth necks. A gentle brushing technique and gingival massage are of particular significance for individuals with bleeding from the gums and disorders of the periodontium (periodontosis). The frequently occurring injuries to teeth and gums by the toothbrush can be avoided. The sensitivity of the fingertip in this case facilitates and simplifies the systematic brushing technique. The foreign-body feeling in the region of the molar teeth caused by the toothbrush in sensitive individuals can be avoided. The dental finger cap is specially suitable for the gentle cleaning of teeth and massage of the gums (also pumping movements) after treatment of parodontosis. The dental finger cap consists of a rubber-like finger cover having an active surface of predetermined shape and size which can be optionally fitted with bristles or rubber knobs and allows charging with a medicament. By welding dental floss at the ends of two finger caps for thumb and index finger, handling of dental floss for care of the interdental surfaces is simplified. <IMAGE>
