Title: Process for preparing guanidine nitrate from a mixture of urea and ammonium nitrate and apparatuses for carrying it out
Inventor: THOMA MATTHIAS
Filed: 1981-03-25
Abstract: In a process for preparing guanidine nitrate from a mixture of urea and ammonium nitrate in the presence of a silicon-oxide-containing catalyst at elevated temperature, the starting mixture of urea and ammonium nitrate having an ammonium nitrate excess, during the course of the process, urea is added stepwise to the particular urea/ammonium nitrate mixture present and the catalyst in amounts such that the weight ratio urea:ammonium nitrate is constantly established in the favour of an ammonium nitrate excess. The weight ratio remains virtually constant during the course of the process and increases only in the final phase. An apparatus for carrying out the process includes a reactor system having one or more tubular heatable reactors which are connected one after the other and each of which are arranged roughly horizontally. The reaction mass is introduced together with the catalyst in the form of a melt and is moved through the reactor system by means of a stirrer and conveyor apparatus. At one or more positions situated upstream of the outlet of the reactor system, inlet nozzles are provided at distances from each other through which the urea and catalyst additions can be fed to the melt. To carry out the process continuously, the reaction mass is applied in the desired layer thickness to one or more heatable conveyor belts connected one after the other. Along the belt, the required additions are fed to the reaction mass. The belt speed of the conveyor belts is selectable, depending on the reaction velocity. <IMAGE>

Title: Cosmic space traffic control centres
Inventor: POISEL OTTO KARL DIPL ING
IPC: B64G99/00
Filed: 1981-11-17
Abstract: This invention should basically be split into two configuration sizes. The smaller configuration is used as an on-board display and an automatic flight control system in flying objects used in cosmic space flight. The larger configuration is used in the cosmic space flight centre and is responsible for recording, monitoring and co-ordination of all cosmic space flights. Each cosmic space traffic control centre comprises a solar system life clock with a cosmic data ribbon display screen (1), the miniature solar system model (2) and nine miniature planet models (3 to 11). All the movements of all the planes as well as the moons and satellites are guaranteed by a long-term uninterrupted power supply. In addition, each planet, moon and satellite has its own life clock, all the life clocks being matched to one another. Even heavenly bodies/flight objects which we have created artificially are visible, with their own mathematical movement relationships, and their flight paths can be tracked, monitored and co-ordinated. Successful cosmic exploration is impossible without cosmic space traffic control centres of both types, since blind flights are deadly. <IMAGE>

Title: Process for producing a synthetic wood veneer
Inventor: HIRAO SHOZO
IPC: B44C3/12
Filed: 1981-12-08
Abstract: For producing synthetic wood veneers, first of all a synthetic material block (2), cut in each case from certain types of inexpensive natural woods and arranged in veneer material layers (1) one on top of the other, is formed. This synthetic material block (2) is divided into slices in such a direction that a straight grain pattern is formed. In this way, so-called collective veneers (4) are obtained, in which the joining surfaces between the various veneer material layers (1) extend parallel to one another and in the direction of the thickness. A multiplicity of such collective veneers (4) is then arranged in layers one on top of the other with veneer material layers (1) cut from another type of natural wood, pressed and united to form a second synthetic material block (6), which is then cut into slices in such a direction that a grain which is very similar to the flame-shaped or flower-shaped grain of natural precious woods is obtained. <IMAGE>

Title: Compositions for resistors, and resistors fabricated therefrom
Inventor: ASADA EIICHI
IPC: H01C17/065
Filed: 1982-12-21
Abstract: A novel composition for resistors is provided which contains a) ruthenium oxide, b) glass, c) at least one metal oxide from the group comprising lanthanum oxide, neodymium oxide, praseodymium oxide and samarium oxide and d) an organic carrier. Further, resistors are provided which have been fabricated using the composition by stoving onto an electrically insulating substrate a resistive film which contains ruthenium oxide, glass and at least one metal oxide from the group comprising lanthanum oxide, neodymium oxide, praseodymium oxide and samarium oxide. The use of the metal oxides in the compositions for resistors surprisingly improves the TCR value (temperature coefficient of the resistor), especially in ranges of high resistance, and brings the TCR value close to zero. In addition to the effect of improving the TCR value, the metal oxides increase the resistance and improve the noise and VCR properties (voltage coefficient of the resistor).
