Patent DE-3025640-A1 (DE)
Title: Protectively coating dumped coal in mining - with aq. nonionic wetting agent-contg. soln. thickened with magnesium hydroxide
Inventor: LEWER HANS
IPC: E21F5/06
Filed: 1980-07-07
Abstract: Aq. CaC12 and/or MgC12 solns. contg. nonionic wetting agents, gel thickened by Mg hydroxide, are used to cover dumped coal residues in mining. The cover layer applied is 2-5 cm thick. Aq. solns. are used pref. contg., by wt., 1-4% Mg hydroxide, 20-35% CaC12 and/or MgC12, calculated as the anhydrous salts, and 0.5-2% nonionic wetting agent. The cover layer protects coal against oxidn. and self-ignition. Should the layer be damaged, then CO2, generated on ignition, reacts with Mg hydroxide to form Mg carbonate. Wetting agent-contg. soln. is released from gel structure, distributes over coal surface and prevents further oxidn. and heating. The thickened solns. are easily pumped under pressure.

Title: Optical interference measurement of mutually inclined surfaces - using aperture or diffraction grid gap system eliminating readjustment
Inventor: ERBEN ALOIS DIPL PHYS
IPC: G01B11/26
Filed: 1980-08-29
Abstract: An interference optical device for measuring geometric dimensions of test objects is esp. for examination of surfaces at angles to each other as in threads. An aperture is placed in the focal plane of a collimator or diffraction grid to produce two or more light beams inclined at different angles to the tangential plane at the measurement point. A part of each beam is reflected from the object and the other part passes directly to a measurement microscope. The aperture or diffraction grid are designed to eliminate the need to readjust them for examination of different surfaces or edges of the object. The aperture or grid has transparent openings (12) corresp. to two differently aligned gap systems. This may be achieved by using two apertures or grids w.r.t. each other about the optical axis.

Their movement in the direction of weft insertion is so controlled that the free ends of tubes meet at about the centre of the shed to transfer the weft from one to the other. There is a guide tube for the material coaxial to the gripper tubes and pref. the same length as them. The operation improves weft yarn insertion over a wide jet loom, particularly when working with a double shed.
Patent DE-3105939-A1 (DE)
Title: Indirect solid-fuel heating
Inventor: MAURER KARLHEINZ
IPC: F24H1/22
Filed: 1981-02-18
Abstract: At present, there is no comparable offer on the market for the abovementioned system. The construction of this heating boiler is based on obtaining the greatest possible efficiency from the smallest possible combustion chamber. This is only possible, however, by converting the heat. Since no heat is withdrawn directly from the boiler water, but is transferred indirectly to the hot-air heat exchanger (closed heating circuit) integrated in the boiler, high temperatures are thus always guaranteed. There is no danger for the boiler at excess temperatures since it is connected to an open expansion tank (evaporator). This system can also be operated by means of water, but for this purpose the installation of a thermal circulation-prevention means or discharge-prevention means is necessary. The system is designed such that it can be easily maintained and cleaned by any operator.

Title: Antenna system with a dielectric
Inventor: BISCHOFF MICHAEL DIPL ING
IPC: H01Q19/12
Filed: 1981-08-28
Abstract: An antenna (aerial) system contains as the element which forms its polar diagram, to produce a receiving antenna, a combination of a hemisphere consisting of dielectric material and a circular disc, which rests flat on the cut surface of this hemisphere, that side of the disc which faces away from the hemisphere being curved in a parabolic shape and being constructed to be reflective. The azimuth beam forming (focusing) is governed essentially by the dimensions and the construction of the hemisphere, while in contrast the beam formation in elevation is determined by the shape of the parabolically curved disc.

Title: Indicator system for motor vehicles
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60Q1/30
Filed: 1981-09-02
Abstract: The invention relates to an indicator system, constructed as a reflector (1), for motor vehicles, which is composed of three lights with the traffic colours and is mounted at the rear of vehicles. The switching logic is constructed in such a way that the green light (2) is operational when the accelerator pedal is actuated, the yellow light (3) is operational when the accelerator pedal is not actuated, and the red light (4) is operational when the brake pedal is actuated. The advantage of an indicator system of this type lies in the fact that in particular when travelling in backed-up traffic drivers are given more comprehensive information on the driving state of the vehicle travelling ahead and a driver can be given earlier warning of braking by the lighting-up of the yellow lamp (3) which of course is always actuated before the red lamp (4) and the brake lights. <IMAGE>

Patent DE-3220078-A1 (DE)
Title: Process for producing and fastening the flared ends to the fork and to the rear structure of bicycle frames
Inventor: MAIER DIETER DIPL ING
IPC: B62K19/10
Filed: 1982-05-28
Abstract: The invention relates to a process for producing and fastening the flared ends to the fork and to the rear structure of the frame of bicycles by the soldering or welding on of stamped-out sheet-metal parts. In this process, plane sheet-metal plates are knocked off from a coil and are soldered or welded to the flared ends. Subsequently, the flared ends are introduced into a stamping tool and stamped. This achieves the object of avoiding the need for any bending and straightening work after the soldering or welding on, because alignment takes place simultaneously with the stamping. Instead of individual sheet-metal plates, sheet-metal strips bent in a U-shape manner can also be used. The soldered-on or welded-on sheet-metal plates can be supplied by means of a slide. The double-acting stamping tool can also be used on touring cycles, for flattening and simultaneously stamping the flared ends.

Title: Radio relay transmission system
Inventor: NIEMEYER MICHAEL DIPL ING DR
IPC: H04B7/10
Filed: 1982-07-21
Abstract: The low coherence-bandwidth amplitude distortions occurring in broadband applications as a result of reflection on a plurality of atmospheric layers or on the surface of the earth, and therefore on the basis of a relatively long propagation time difference between this reflection deviation (P3) and the direct useful propagation path (P1) of an LOS (line-of-sight) radio relay path, are prevented when the transmitting and/or receiving antenna (1, 2) has an extremely narrow radiation pattern which allows an adequate evaluation between the direct useful propagation path (P1) and a reflection deviation (P2) with a slightly different propagation time compared with the former, and when the aforementioned antenna radiation pattern which is designed so that it can pivot in the vertical plane is swung into a position in which the signals supplementing themselves vectorially, which are transmitted on the one hand via the direct useful propagation path (P1) and on the other hand via the reflection deviation (P2) with a different propagation time compared with the former have substantial amplitude differences or at least an approximately similar phase angle. The effect of the measures according to the invention is that the transmission of high-speed data suffers neither interference nor temporary interruption due to possible multipath propagation. The invention is particularly suitable for use in digital LOS radio relay systems. <IMAGE>

Title: Gas-turbine jet engine having force-control properties for use on aircraft which take off on their tails
Inventor: KASTENS KARL DIPL ING
IPC: B64C29/00
Filed: 1982-07-22
Abstract: In this gas-turbine jet engine having force-control properties for use on aircraft which take off on their tails, an air-inlet housing (4) having integrated transverse-flow fans and lateral-force thrust nozzles (7) on the one hand and a compressor-turbine housing (6) together with the connected jetpipe (8) on the other hand are supported, according to the drawing in Fig. 1, jointly on a turbine shaft and are adjustable independently of one another by means of a pivoting transmission located in the axle shaft, but are installed such that they can be fixed in any desired angular position, by means of the brake-laminate stacks. The axle shaft is thus rigidly connected to the aircraft fuselage (45). In general, the aircraft which takes off on its tail is preferably suitable for the use of the jet engine according to the invention, take-offs and landings being ensured without the normal fixed-position auxiliary apparatuses (take-off ramps and the like) and takes over all the flight-attitude control, in that the lateral-force component (42) remains parallel to the pitch axis in an unchanging manner, while the vector of the lifting thrust force (21) is arranged radially with respect to the turbine shaft and covers a pivoting angle of approximately 180 DEG . At the same time, the vector-pivoting plane runs parallel to the aircraft longitudinal plane. <IMAGE>
