Patent DE-3209352-A1 (DE)
Title: Process for the recovery of heat energy through the combustion of coal, and fuel element for the performance of the process
Inventor: WINKLER ERWIN
IPC: C10L5/38
Filed: 1982-03-15
Abstract: The coal is first gasified and calcined by external heat in a clay container, and the combustible gases arising from the gasification emerge from the clay container and are burnt. The residues of the coal remaining in the clay container are then calcined and burnt. The heated clay container with the incombustible residual materials, such as ash and slag, contained in it is then cooled. The coal can be comminuted before being filled into the clay container and mixed to a sludge with comminuted, hard-burning clay and then introduced into the clay container. A fuel element (1,1a) can be used for performing the process which consists of a hollow container (2,2a) with a casing (3) of clay. A fuel core (5) is arranged in the hollow container (2,2a) and has formed in it an air supply chamber (6). This chamber is connected to the atmosphere adjacent to the outer surface (9) of the casing (3) of the hollow container (2,2a) by means of gas outlet channels (8). The hollow container (2) is expediently of parallelepipedal shape with a rectangular or square cross section. The hollow container (2a) can have a generally cylindrical cross section. <IMAGE>

Title: Anti-slip tread-surface unit with metal load-bearing structure
Inventor: NICKLAS GUENTER
IPC: E04F11/16
Filed: 1982-05-03
Abstract: Anti-slip tread-surface unit, in particular for use outdoors and in rooms which are exposed to moisture, for example as step, for landings, walkways, platforms (working platforms) and tread surfaces in swimming pools, with a metal load-bearing structure in the form of a zinc-coated steel sheet. The novelty of the invention is that a rectangular metal sheet, which is obliquely positioned such that it runs slightly (approximately in the order of magnitude of 2%) downwards in the direction of one of its longitudinal and, on its two longitudinal sides, has bent-off portions directed downwards through 90 DEG , is fixedly connected, for example welded, along its two narrow sides, to side sheets which project beyond the two bent-off portions and beyond the upper side of the metal sheet itself. On the upper side of the metal sheet, reaching to the upper edge of the two side sheets, and along the bent-off legs on either side of the metal sheet, reaching to the lower end edges of said legs, there is applied a liquid-permeable outer coat which consists, in a manner known per se, of rubber granules, having a grain size of approximately 2 to 8 mm, a curable binder and, if appropriate, an additive for facilitating processing (preventing adhesive bonding of the material onto the processing tools).

Patent DE-3229720-A1 (DE)
Title: Hydrodynamic cleaning device, preferably for the outer walls of ships
Inventor: HAMMELMANN PAUL
IPC: B63B59/06
Filed: 1982-08-10
Abstract: The cleaning device used preferably for the outer walls of ships is equipped with at least one spray nozzle which is fed with pressurised water and mounted and driven so as to rotate about an axis. The spray nozzles are assigned a discharge propeller (3) whose axis of rotation coincides with the axis of rotation of the spray nozzles. The spray nozzles and the discharge propellers are arranged in a housing (1) which is open towards the surface to be cleaned and has a brush seal which is supported during operation on the surface to be cleaned. The colour residues, particles of dirt or the like which are released from the surface to be cleaned are fed, together with the washing water, out of the housing (1) into a feed line (20) from which the contaminated dirty water passes into a cyclone (24). The heavy particles are drawn out of the cyclone into a dirt container (25). The precleaned water passes from the cyclone into a water tank (26) into which the suction line (27) of a high-pressure pump (7) opens. The suction water passes via a prepressure pump (28) and a filter (29) into the suction space of the high-pressure pump (7) from which the pressurised water is fed via a pressurised water line (6) to the spray nozzles arranged in the housing (1). <IMAGE>
Patent DE-3229837-A1 (DE)
Title: Process for the preparation of nacreous pigments
Inventor: FISCHER ROBERT DIPL CHEM
IPC: C09C1/00
Filed: 1982-08-11
Abstract: Known nacreous pigments based on mica platelets coated with metal oxides, in particular TiO2, cannot be prepared in all shades. The application of coloured oxides from aqueous solution produces large amounts of wastewater and still does not make it possible to obtain all conceivable colour combinations. A comprehensive range of colours is now obtained by treating the coated platelet-like particles with colour-conferring metal compounds dissolved in organic solvents, preferably with lustre colours.
Patent DE-3235562-A1 (DE)
Title: Bottle closure with dispensing device
IPC: B67D1/04
Filed: 1982-09-25
Abstract: Traditional German siphon bottles for beer mostly have a capacity of 2 l. They have a large outlet diameter and are sealed by a clip lock.   Beer cannot be dispensed from this large bottle outlet in a manner suitable for beer, giving an attractive frothy head. For this reason, according to the invention, a bottle dispensing-closure has been created, which permits this and moreover does not allow the beer to go flat, since it is held under pressure. The chief problem of the securing of this bottle closure was solved according to the invention by a projecting retaining clip, which grips beneath the pivot bearing of the porcelain closure. To compensate for differing bottle diameters, according to the invention a stepped tensioning block has been provided at the bottle closure, which, by means of the wire clip lock, as a result of its steps, can be tensioned to a greater or lesser extent.
Patent DE-3236965-A1 (DE)
Title: Detachable pipe connection
Inventor: KRAMM OTTO DIPL ING
IPC: E03F3/04
Filed: 1982-10-06
Abstract: Concrete pipes or other ceramic pipes for sewage, heating or water pipelines and similar applications are normally assembled using sleeve-like connections with a rubber sealing ring inserted between them. Since, during production of the connections, the sealing rings have to carry out relatively long linear relative movements on the pipe ends which are pushed into one another, they are to be treated with special sliding agents before assembly in order to avoid damage or displacement. According to the invention, an antistatic agent, for example an antistatic softening agent, is added to the rubber mixture. This makes it possible simply to use water instead of the special sliding agent solutions, which are often difficult to obtain on building sites, and hence to provide the desired sliding effect.
Patent DE-3238909-A1 (DE)
Title: Process for drying fused salts
Inventor: EREN YALCIN DIPL ING
IPC: H01M10/39
Filed: 1982-10-21
Abstract: The fused electrolytes which are used in high-temperature galvanic cells and consist primarily of Li salts can be dried and freed of hydrolysis products by adding metals such as Be, Ca, Mg, Th and Y. These metals react with H2O to form oxides which are chemically more stable than any active material present in the cell, including the electrolyte salts (Li, LiAl, LiF, LiCl, LiBr). With these substances, H2O present as an impurity will otherwise form oxides, hydroxides and hydrides, some of which increase the electron conductivity of the fused salt during charging as a result of the oxidising effect and consequently promote the undesirable self-discharge of the cell.
Patent DE-3239306-A1 (DE)
Title: Scanning system with vertical magnetisation
Inventor: SCHOLZ WERNER DIPL ING
IPC: G11B15/61
Filed: 1982-10-23
Abstract: In a recording operation with vertical magnetisation, two poles (4, 11) are located on opposite sides of the recording medium (1). According to the invention, the first pole (11) is fixed and extends over the length of the recording track (5), whereas the second pole (4) is designed approximately in the form of a point and is movable along the track (5). As a result, the structural design of a head wheel (3) bearing a plurality of poles (4) can be simplified considerably. In particular, only the fixed pole (11) bears a winding (12), effective for all the moving poles (4). <IMAGE>

Patent DE-3240996-A1 (DE)
Title: Process for manufacturing thick-walled mouldings from thermoplastics
Inventor: BECK ERICH ING GRAD
IPC: B29C37/00
Filed: 1982-11-06
Abstract: The invention relates to a process for manufacturing large-format, thick-walled mouldings without the application of pressure. It permits a considerable reduction of the mould costs by the use of metal sheet, wood or polyester sheets as mould material. The filling of the moulds is carried out by mechanical or manual insertion of the molten sections extruded from a melt unit. The surface structure of the mouldings can be influenced by the application of more or less intensive stamping of the molten sections. A shrinkage with cooling is counteracted by the insertion of expansion bodies. <IMAGE>

Title: Circuit arrangement for measuring respiration rate and breathing time ratio
Inventor: ABENDROTH MANFRED DR ING
IPC: A61B5/08
Filed: 1984-01-13
Abstract: The invention relates to a circuit arrangement for measuring respiration rate and breathing time ratio, having a switch for changing over from the measurement of respiration rate to the measurement of breathing time ratio, and the optionally optical display of same, to which there are applied inspiration and expiration signals from an anaesthesia or therapy breathing apparatus, as well as signals from a square-wave generator. The circuit arrangement has a sequential control with three pulse contraction circuits, which drives a D flip-flop and two 4-bit shift registers. The latter accept the counting results from a counting flip flop and two 4-bit binary counters, which results form the address for a programmable read-only memory. The address contents are decoded and optically displayed. An alarm is triggered upon undershooting of the respiration rate of 6 min<-1>. Advantages of the solution according to the invention reside in that information is provided without delay on the respiration rate or the breathing time ratio. In this case, the result is of high accuracy. The ease with which the results can be read out is favourably effected by the digital display of figures. The solution can be applied in anaesthesia and therapy breathing apparatuses, as well as in frequency monitors.
