Patent DE-3048351-A1 (DE)
Inventor: MOSKAU GERHARD ING GRAD
IPC: C02F11/13
Filed: 1980-12-20
Abstract: Aqueous sludges containing combustible substances are oxidised under pressure and elevated temperature in an oven. The gas-steam mixture produced during the oxidation is utilised by indirect heat exchange to thicken the sludge to be oxidised. This involves bringing the gas-steam mixture into contact, directly or via a heat exchanger, with the heat transfer medium. The useful heat of the gas-steam mixture passes into the heat transfer medium and is employed to thicken the sludge. The heat transfer medium employed may be the condensed water of the gas-steam mixture or a substance whose boiling point is above that of water. An apparatus serving this purpose contains a film evaporator (2) whose heating chamber (11) is filled with condensate water and has a valve tray (16) through which the gas-steam mixture is introduced into the condensate water. In an alternative embodiment, a separate heat exchanger which is fashioned as a mixed condenser and filled with condensate water is provided. The gas-steam mixture is introduced into the condensate water through a valve tray. The heated condensate water is then passed to the heating chamber (11) of the film evaporator (2). <IMAGE>

Title: Method and arrangement for error location in a digital transmission path
Inventor: JUNGMEISTER HANS DR ING
IPC: H04B17/40
Filed: 1981-03-10
Abstract: Digital transmission paths can be tested in a known manner during operation by operational monitoring circuits which, for example, identify code rule violations. Outside operation, it is possible to effect a loop closure via remote control from a central station in individual regenerative repeaters and to transmit test signals via this loop closure. In optical waveguide paths and coaxial paths with a very high bit rate, difficulties arise in setting up the loop closure facilities. It is therefore proposed according to the invention to transmit a plurality of test signals with defined and different DC contents consecutively outside operation and to transmit an indication signal corresponding to the identified DC content to a connected signalling channel in every intermediate station which is to be located. The invention can be used advantageously in particular in optical waveguide paths and in digital transmission paths with a bit rate of several 100 MBit/s. <IMAGE>
Patent DE-3117713-A1 (DE)
Title: Process and device for the spray-coating of articles with powder
Inventor: MENDLER HANS
IPC: B05D1/06
Filed: 1981-05-05
Abstract: The coating rate during the coating of moving articles with powder is increased. For this purpose the powder is acted on in such a manner that when incident on an article to be coated it immediately adheres strongly to the latter. Furthermore, a gas curtain is produced behind the atomised powder cloud, which prevents entrainment and swirling of powder particles from the powder spray jet and deposits powder particles passing into the gas curtain on the article in a short time without a rebound effect. The large amount of powder necessary for rapid coating is preferably sprayed by a multiplicity of individual nozzles, to which powder is fed separately and adjustably and also without rebound. The individual nozzles together form a single powder cloud.

Title: Light-emitting-diode component and indicating lights equipped therewith
Inventor: KRAUTWALD HERBERT
IPC: G09F9/33
Filed: 1981-08-18
Abstract: The light-emitting-diode component exhibits a plurality of light-emitting crystals (1), which are disposed in recesses (3) of a common metal carrier (2). The recesses (3) are open in the direction of the emission of radiation, and are designed to be of parabolic configuration at the lateral surfaces (3a) and plane at the base surface (3b) and mirror-coated on the surface. The respective connecting points (1a, 1b) of the crystals (1) are electrically connected to one another and attached to a pair of connecting pins (4), which is embedded in the carrier (2) in an electrically insulated manner (5). The light-emitting-diode component exhibits a common covering cap (6), which is secured (7,8) to the carrier (2) and which is disposed directly over the crystals (1) and possesses, in this region (9), concave, lens-type, transparent surfaces which permit a preferred light exit. Such components may exhibit differing shapes as a result of differing types of arrangement of the crystals. By the combination of differently configured light-emitting-diode components, it is possible to produce indicating lights with different types of symbol indications. <IMAGE>
Patent DE-3134813-A1 (DE)
Title: Microwave anti-shoplifting system
Inventor: KLIR VILEM
IPC: G08B13/24
Filed: 1981-09-03
Abstract: In the anti-shoplifting field, a number of systems have already been proposed. These systems have the following disadvantages:   1) The transmitter and receiving antennas are predominantly constructed as frame antennas and the width of the passage is in many cases less than 1.5 m, which represents an obstacle at the shop exit.   2) The marks have relatively large dimensions and are mainly attached visibly so that the mark can be easily found and removed.   According to the invention these problems are solved by a high microwave frequency (above 4 GHz) being used for the system. The antenna system is very small and is exclusively mounted on the ceiling of the control space so that assembly is very simple and this solution represents a significant improvement of the prior art for design and fire prevention reasons. Due to the very high operating frequency, it is possible to reduce the dimensions of the control marks by a factor of 4 to 10 so that the mark can be preferably attached to the goods in a concealed manner. Figure 2 shows the technical layout of the system. The microwave oscillations (above 4 GHz) are generated in the microwave oscillator (1), modulated by the modulator (2) and radiated via the transmitter antenna (3). A mark (4) which is not devalued (the marks are devalued at the cash register in a sale - the frequency conversion characteristic of the mark is destroyed) causes frequency conversion. This frequency is received in the receiving antenna (5), demodulated in the demodulator (6) and processed in the analyser (7). The control box (8) then indicates an alarm and outputs a control command (for example closing of the door). <IMAGE>

Title: Cable reel with an integrated illumination intensity regulator for standard lamps and table lamps
Inventor: SCHUCHARDT KAETHE
IPC: H02G11/02
Filed: 1981-11-05
Abstract: The invention relates to a cable reel with an integrated illumination intensity regulator for standard lamps and table lamps. The cable reel, which is supported such that it can rotate in the lamp foot, has a free space in the centre for holding a commercially available illumination intensity regulator. When a completely electronic regulator is used, switching and dimming take place via a sensor surface located on the foot of the lamp. When a regulator having a rotary potentiometer is used, said regulation is achieved by rotating the lamp pillar over a rotation range of max. 180 DEG . The mechanical connection between the lamp pillar and the regulator is produced by means of a [lacuna] in a 180 DEG  slotted hollow shaft, from which the driver of a centre axis projects. The lamp column, which is suspended in a resilient manner, is simultaneously used to operate the on-off pressure switch, located in the upper part of the lamp, by vertical displacement.

Title: Amateur slide mounting apparatus
Inventor: POHL CLAUS DIPL ING
IPC: G03D15/10
Filed: 1981-12-04
Abstract: An amateur apparatus is described for cutting developed film strips into slides to introduce these into an elastically openable entry slot of a slide mount. The aim is achieved of improving such an amateur apparatus in such a manner that the two functions, cutting and mounting the slide, are combined in the apparatus without great technical effort, and the separated slide is not adversely affected by fingerprints and/or scratches on the sensitive film layer even without special brushing in advance. The aim is achieved in that the apparatus has a guide part for the mount in which a deformation element is arranged, by means of which the mount is deformed in such a way that an entry slot is formed. In a mount position of the guide path, a guide path joins the film strip. At this point, a blade is arranged to separate off the film section from the film strip. In the direction of transport of the mount, a wedge-shaped ramp is provided in the rear section of the guide path for the mount, by means of which ramp the separated slide can be pushed into its final position in the mount.

Title: Bearing for machine and drive parts as well as for a pump having a permanent-magnet clutch
Inventor: FICHTNER HANS E
IPC: F04D13/02
Filed: 1982-06-03
Abstract: The invention relates to a bearing for machine and drive parts and for the impeller of a pump having a permanent-magnetic clutch, in which to achieve a hermetic sealing of the delivery medium from the surroundings a split pot is arranged between the driver and the coupling rotor. The bearing essentially comprises a radial permanent-magnet bearing and a supporting bearing, it being possible to displace the fixed magnet arrangement of the permanent-magnet bearing eccentrically in relation to the respective impeller to such an extent that in the radial direction the position of equilibrium resulting from the loading and the magnetic forces coincides with the desired position of the impeller, maintained by the supporting bearing. The supporting bearing comprises in particular a mounting between centres. This results in an essentially contactless bearing, the remaining frictional surfaces of which are extremely small in area, so that high-quality materials can be used to achieve a very long service life.

Title: Transformer-fed bridge rectifier
Inventor: PIVIT ERICH DR ING
IPC: H02M7/162
Filed: 1982-09-14
Abstract: The invention relates to a transformer-fed bridge rectifier for generating a high direct voltage and is characterised by the fact that the secondary windings of the transformer are electrically isolated from one another and are in each case located in the cross branch of a two-way rectifier bridge, and that the longitudinal branches of the individual bridges are connected in series. Such a bridge rectifier is particularly suitable for generating high voltages and offers the advantages of a lower power dissipation of the transformer or of a smaller constructional volume with the same power, the advantage of low harmonics and the advantage of lower insulation strength needed.
