Title: Device for eliminating and reintroducing friction bodies inside the circuit of a heat exchanger
Inventor: O DIPL-ING RIEDEL ERICH
IPC: F28G1/12
Filed: 1982-06-16
Abstract: The invention relates to the elimination and reintroduction of friction bodies inside the circuit of a heat exchanger by means of filter surfaces switched into the external water circuit, which is guided in tubes, the opening width of said filter surfaces being smaller than the smallest diameter of the friction bodies. As Fig. 1 shows, for this purpose there is arranged in the tube housing and at the outlet of the filter surfaces a collecting tube in the normal to the large tube axis (X), which collecting tube is provided with two openings which are constructed as longitudinal slots and extend parallel to the circumferential line. Two further openings release a controlled water passage. A rotary valve is arranged in the tube body. In the operating position, the filter surfaces guide the friction bodies into the collecting tube and further into the rotary valve. After rotation of the rotary valve by 90 DEG , the friction bodies are conveyed from there into the feed by a pressure water hammer.

Title: Process for reducing the dewpoint temperature of the waste gases of a fuel-operated heating boiler
IPC: F23J15/08
Filed: 1982-12-04
Abstract: The invention relates to a process for reducing the dewpoint temperature of the waste gases of a fuel-operated heating boiler, in which the heating gases, after flowing through the heating gas paths situated in the heating boiler, are conducted as waste gases through a condenser. The dewpoint temperature of the waste gases is reduced by heating the waste gas to a higher temperature after its exit from the condenser. This heating is possible by connecting in a heat exchanger, the hot side of which is acted upon by hot heating gases which are subsequently conducted back into the heating boiler. It is also possible to achieve heating by adding hot heating gases to the waste gases.

Title: Method for the portioned delivery of drinks
IPC: B65D75/58
Filed: 1983-02-02
Abstract: According to the invention, drinks are intermittently portioned from an inexpensive plastic bag or a corresponding thin-layered bag which is wound up inside a delivery container which has a spiral spring which is formed from a film-like strip with a constant spring pressure, which squeezes the entire drink contents from the bag and which continuously generates delivery power. The spiral spring strip may be made of plastic, metal, an elastomer or a fibrous material and may form one side of the bag, so that a container which is suitable for the storage of flowable fluids, including carbonated drinks, and with which it is possible to deliver a specified portion at a specified time can be manufactured at very low cost. This delivery method ensures that a continuous pressure on the stored fluid is maintained, both during delivery and during storage in the bag, it being possible to deliver portions intermittently and repeatedly and delivery being automatic, without manual pressure on the container. The proportion of carbon dioxide in drinks which contain it is accordingly maintained as a result of spring pressure, the pressure preventing the escape of carbon dioxide at normal delivery temperatures. Delivery is automatic, without the entry of air or impurities into the ... Original abstract incomplete.

Title: Epoxide-phosphoric adducts and process for their preparation
Inventor: LOTTERMOSER MANFRED DIPL PHYS
IPC: C09K23/14
Filed: 1983-02-09
Abstract: Unsaturated compounds are reacted with peroxides, for example hydrogen peroxide, and phosphorus pentoxide in heterogeneous or homogeneous reaction systems to give hydrolysis-resistant phosphoric acid esters. For example, 35% strength hydrogen peroxide is reacted with phosphorus pentoxide and gives the unsaturated compound. Inter alia, unsaturated vegetable oils, all types of alkenes or oligostyrenes prepared from polystyrene wastes can be converted into phosphoric acid esters. The average molecular sizes and the content of free phosphoric acid groups can be varied within wide limits. The alkali metal and alkanolamine salts of the esters containing free phosphoric acid groups are water-soluble. Use areas are, inter alia: lubrication technology, metal processing, rust conversion, post-protection, hydrophobisation, antistatics, pretreatment of fibres for fibre-reinforced plastics, builders for detergents, and masonry and construction preservation.

Title: Process for separating pollutants from process gases
Inventor: GATTYS F J DIPL ING
IPC: B01D53/14
Filed: 1983-02-10
Abstract: Process for separating pollutants, for example nitrogen oxides, chlorine gas, hydrogen chloride, sulphur dioxide, indium chloride or hydrocarbons, from process gases in which the gas is passed into a bath of a pollutant-specific liquid or dissolved absorbent. Absorbent is sprayed in a small amount as a liquid phase into the process gas and is separated directly afterward, after being enriched with the pollutant, whereupon the process gas is brought into contact with a large amount of liquid absorbent having a low partial pressure of pollutant. In this case, prior to spraying the required amount of pure absorbent as liquid phase, an amount of absorbent sufficient to saturate the process gas with pure absorbent liquid is added to the process gas. The absorbent enriched with pollutants produced at the separator can be discharged and fed directly to a further processing step or it can be returned to the bath of the circulation vessel. The absorbtion is carried out in a lamellar separator having a built-in nozzle section.

Title: Receiving antenna for very-high frequencies
Inventor: POTSCHKAT GUENTER
IPC: H01Q9/14
Filed: 1983-03-16
Abstract: In order to increase the bandwidth and to reduce the structural heights in a receiving antenna for very-high frequencies which is constructed in the manner of a coaxial antenna, especially for microphone signals which are transmitted by wireless means, it is proposed to fit two ferrite sections, having different 1/d ratios and an essentially low permeability, isolated from one another between the two metal tube sections. One of the two ferrite sections is surrounded by the coil windings of two associated LC resonant circuits which have different centre frequencies and are essentially not coupled to one another. Furthermore, the LC resonant circuits are in each case connected, via an associated decoupling coil, to a transformer which is connected to the coaxial connecting cable, which transformer transforms the overall impedances of the antenna, which are effective in the decoupling coils, to the characteristic impedance of the connecting cable, and carries out the reversal in balancing.

Title: Method for operating terminals of a digital subscriber connection
Inventor: KRAUTKRAEMER WILLFRIED DIPL IN
IPC: H04M19/08
Filed: 1983-03-29
Abstract: If a multiplicity of terminals which are fed via a power supply device are connected to a subscriber interface at the subscriber end, where data are transmitted and power is supplied via a common multi-wire data line, and if an additional power supply is provided from the switching system via the subscriber connection line which is only sufficient to supply a small number of terminals, a continuous signal is transmitted onto the data line if the power supply device fails, whereby all those terminals are de-activated via detection devices which evaluate the continuous signal and only the terminal which is intended to remain operational is not fitted with a detection device of this type. In this way, it is ensured that terminals can be disconnected from the data line during the power supply device failure and can be re-connected to the data line without being in the standby mode.

Title: Regenerative heat engine
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G1/04
Filed: 1983-07-29
Abstract: The regenerative heat engine heated by the supply of heat from outside comprises a working space having the shape of a flat cylinder and filled with high-pressure gas, the periphery and end faces of which are, for example, composed of fine ceramics, in which a displacer having the shape of a flat cylinder and the same axial length but a somewhat smaller diameter is made to revolve by an auxiliary motor via an eccentric and in which two partial volumes with a high and a low temperature are separated off by resiliently guided sealing strips arranged diametrically on the casing. The periodic change in the volumes of the partial spaces (while the total volume remains constant) gives rise to large periodic changes in the pressure of the working gas and, made to act in the same direction by non-return valves, these charge two pressure vessels with different pressures. Mechanical power is produced by expansion in an expansion motor of known design. If a fluid separator is introduced, the pressure accumulation means and the expansion motor can be operated with a medium which is different from the working gas, e.g. with a hydraulic-nitrogen mixture.

Title: Whole-body application device for magnetic field therapy
Inventor: GENSKY THOMAS
IPC: A61N2/04
Filed: 1983-10-13
Abstract: It is known that the bioenergetic processes in the living organism can be favourably influenced with a pulsating magnetic field. The inductive effect on the living organism leads to atomic molecular activation and can accordingly produce a state of energetic equilibrium, where this is disturbed. The invention is based on the object of making magnetic field therapy accessible even to patients whom it has hitherto been impossible to treat with the customary application forms because they had severe physical disabilities. Up to now, because of their disabilities, therapy with the previously customary application forms could not be made accessible to exactly that circle of patients who would have most urgently needed magnetic field therapy. This object is achieved, according to the invention, in that the rectangular applicator is pushed over the lying patient, so that magnetic application has become possible without the slightest physical exertion by the patient. Furthermore, the new whole-body application unit for magnetic field therapy can now be used to treat the entire human organ system, so that the healing effect of the pulsating magnetic energies can be utilised much more optimally.
