Patent DE-3113005-A1 (DE)
Inventor: LENZ SIGMUND
IPC: H04B7/005
Filed: 1981-04-01
Abstract: A method for compensating nonlinearities of a transmission member in a radio relay transmission system by means of a linear converter having a linear gain characteristic and a harmonic generator converter having a nonlinear characteristic, in which an intermediate frequency signal modulated a useful signal is converted by a local oscillator signal into a radio frequency signal and the output signals of the two converters are linked together by a network. The method further includes: setting the operating point of the harmonic generator converter in a manner to cause its output signal to be essentially composed of components corresponding to the useful signal and to third order intermodulation products thereof; modifying the harmonic generator converter output signal by substantially suppressing the useful signal component from that output signal and setting the amplitude of the remaining third order intermodulation products component of that output signal; setting a relative phase position between the modified output signal of the harmonic generator converter and the output signal of the linear converter; and combining the modified output signal of the harmonic generator converter and the output signal of the linear converter subsequent to setting the relative phase position.

Title: Method and apparatus for lining vertical to inclined spaces in underground working, preferably boreholes, with a construction material hardening in a formwork space
Inventor: DUERRFELD WERNER DR ING
IPC: E21D5/00
Filed: 1981-04-14
Abstract: The invention relates to a method and apparatus for lining vertical to inclined spaces in underground working, preferably boreholes, with a construction material, for example concrete, hardening in a formwork space defined on the outside by the side walls of the space and on the inside by a formwork. The formwork skin, after the formwork is placed in the space to be lined by means of its supporting structure, is set to the inner dimensions of the lining and, after the construction material is poured into the form space and has hardened, is relieved of load and then shifted or removed from the space. The purpose of the invention is to line mine spaces having clear cross-sections corresponding to the normal variation in their diameters with a hardening construction material in such a way that, even under unfavourable rock conditions, which are possibly accompanied by an excavation gradient of the rock, the lining is preferably attached frictionally to the rock and in special cases to an existing provisional lining. To this end, provision is made for the formwork skin, consisting of a fabric tubing (17, 21) closed at both ends (22, 23), to be hung with stretched top end (22) into the space (1) and to be set or regulated to the inner dimensions of the lining by filling it with a pressure-exerting medium, forming the supporting structure, over its length adjoining the tubing ends (22, 23) in such a way that, during the filling and hardening of the construction material, the inner pressure of the tubing (17, 21) is kept above the hydrostatic pressure of the construction material, placed in the formwork space (43), until the construction material has hardened, and for the inner pressure to be reduced in order to shift or remove the formwork, and for the tubing (17, 21) to then be released or left as permanent formwork. <IMAGE>
Patent DE-3116483-A1 (DE)
Title: Road reflector post
Inventor: JANIK WERNER
IPC: E01F9/619
Filed: 1981-04-25
Abstract: The road reflector post has an at least partially reflecting inclined surface. Precipitation, such as rainfall for example, frees any dirt sitting on the inclined surface and rinses it off. As a result, the inclined surface is constantly cleaned so that the reflection capacity of the road reflector post remains virtually unchanged in the time between cleanings of the road reflector post, even if it is very soiled. It only has to be cleaned at long time intervals by road-cleaning vehicles, as a result of which the maintenance costs are greatly reduced.

Title: Information transmission technique in space by means of a transmitting and receiving cannon
Inventor: POISEL OTTO KARL DIPL ING
IPC: H04B13/00
Filed: 1981-09-15
Abstract: The invention of space communication at a multiple of the speed of light is based on the principle that an information transmission beam which is produced is accelerated to a specific multiple of the speed of light, and distances of light years are thus bridged in a very short time. The acceleration factor and hence the information transmission speed are dependent on the magnitude of the mass of information carrier particles produced. The information transmitting cannon is composed of a generator (1), a code unit (2), a wave acceleration regulator (3) and a direction changing device (4) for the transmitted beam (5). In contrast to this, the information receiving cannon is composed of a receiving antenna, a wave decelerating regulator, a decoding unit and an information recording apparatus. As a result of these properties, the information transmitting technology by means of these transmitting and receiving cannons is predestined for the purpose of ensuring that we are able to carry out space communication at all for space exploration which will go beyond the limits of our solar system. <IMAGE>

Patent DE-3214276-A1 (DE)
Title: Computer-controlled ignition angle adjustment for spark ignition engines with positive ignition
Inventor: GALL JOHANN
IPC: F02P3/045
Filed: 1982-04-19
Abstract: The need to reduce the fuel consumption and to reduce the emission of noxious substances call for the ignition time point adjustment on spark ignition engines with positive ignition to be optimised. This object is achieved in that a conventional ignition system with mechanical components such as centrifugal force adjuster and partial vacuum adjuster is converted into a characteristic diagram-dependent ignition system by means of a computer-defined control pressure on the partial vacuum adjuster, built up via solenoid valves which are also computer controlled, as a function of the engine operating data present at the computer. This characteristic diagram-controlled ignition system permits a freely selectable adaption of the ignition angle to the engine speed and engine loading taking into account further engine-specific operating data. By the use of electronic auxiliary devices such as a microprocessor, whilst maintaining conventional mechanical ignition angle adjustment devices, on the one hand an optimum ignition angle adjustment is achieved and on the other hand the advantages of the proven, service-friendly and operationally reliable ignition angle adjustment devices are preserved. This system is also particularly suitable for retrofitting vehicles currently in operation with conventional spark ignition engines.

Title: Simple, impressive and convincing model which illustrates the rotation of the earth about its axis with the aid of the sun's rays
Inventor: SCHECK GEB SKLADNY
IPC: G09B23/06
Filed: 1982-07-19
Abstract: A simple, impressive and convincing model illustrates the rotation of the earth about its axis with the aid of the sun's rays. SO-G-SKG-g always produces the solution. Bright solar rays So strike a large vertical article G, a column or pillar 200 x 10 x 10 cm; whose shadow falls over a horizontal surface, table or floor 200 cm away. A small body g, such as a die or book, is placed exactly on the right-hand edge SKG of the shadow. As a result of the rotation of the earth in an anti-clockwise direction the sun's rays So immediately penetrate between the edge SKG of the shadow and book g; the edge of the shadow moves away rapidly clockwise, and the rotation of the earth about its axis is visible and the solution found. Repeated additional movement of g at SKG makes the test more fascinating. The creatively designed teaching and learning model (drawing), set up in open public places, parks and playgrounds at the point which is exposed to the sun's rays from East, South and West, stimulates experiment and explains, in a comprehensible manner, the everyday, unnoticed but interesting phenomenon of the rotation of the earth. <IMAGE>

Patent DE-3243230-A1 (DE)
Title: Circulatory scattering head
Inventor: MARFI KAROLY
IPC: B05B1/34
Filed: 1982-11-23
Abstract: For spraying e.g. plant protection media for paint-spraying, spray guns which are connected via a pressure duct to a pressure source can be used. The spray gun has a nozzle to whose nozzle body the pressure duct can be attached. The liquid to be sprayed is fed to a vortex chamber via a central bore in the nozzle body, flows through the vortex chamber with a helical rotation along an axis coaxial with the nozzle axis, and leaves the nozzle through a spray hole in the nozzle head. The spray hole is of conical shape and is arranged coaxially the long axis of the vortex chamber. The nozzle head is fastened to the nozzle body by means of a sleeve nut. The shape and quantity of the spray stream can be changed, for different liquids, by the shaping of the spin profiles arranged in the region of the spray hole and by the shaping of the spray hole. To prevent settling of impurities, which lead to blockage of the nozzle, in the region of the spin profile, an interchangeable insert piece is arranged in the vortex chamber, and by means of it the axial length of the vortex chamber can be changed.

Title: Screed floating floor
Inventor: DRUM GERD ING GRAD
IPC: E04F15/18
Filed: 1983-03-08
Abstract: During application of a screed floating floor, the edge insulating strip, which produces a lateral insulation between this screed floating floor and the wall of the building, is not, as previously, fastened on the bottom edge of the wall prior to application of the insulating material layer on the crude floor, but is formed as an angled profile, one leg of which is bonded adhesively to the surface of the insulating material layer to the surface after the latter has been applied. It is thus possible, in spite of different thicknesses of insulating material layers, always to use an equally wide edge insulating strip. Moreover, the formation of footstep sound bridges from screed material is prevented as a result of the good seal against liquids between the edge insulating material and the surface of the layer of insulating material.
