Title: Motor drive for displacing the primary longitudinal inclination control devices (elevator and its trimming) in gliders and motor-gliders
Inventor: BLUME MARTIN
IPC: B64C13/22
Filed: 1982-09-22
Abstract: In order to optimise the longitudinal inclination control and to create redundancy in the control about the lateral axis in gliders and motor-gliders, a motor drive directly or indirectly displaces the longitudinal inclination control devices, controlled by a computer which calculates the control signal on the basis of measured variables and stored optimisation models. The pilot is relieved of routine observation and regulation tasks. The previously necessary multiplicity of built-in instruments scattered around the cockpit can be reduced. The redundancy in the control about the lateral axis prevents the aircraft being without control around all the axes if the pilot is incapacitated.

Title: Polymer cell containing inorganic electrolyte
Inventor: KRUGER FRANZ JOSEF DIPL CHEM D
IPC: H01M10/36
Filed: 1983-09-30
Abstract: The performance of galvanic cells containing at least one polymer electrode which can be converted to opposite states of charge by doping with conducting salts can be improved if the electrolyte is composed of a solution of the appropriate conducting salt in an aprotic inorganic solvent instead of common organic solvents. In this connection, in addition to the preferably suitable oxyhalides SOCl2, SO2Cl2 and POCl3, the "water-similar" solvent SO2 is also suitable. Despite its low boiling point this can be used because it forms liquid solvates with salts, its partial steam pressure in said solvates still not being reached at atmospheric pressure at room temperature.

Patent DE-3419992-A1 (DE)
Title: Heterodoping of semiconductor materials
Inventor: SCHULZ MAX J PROF DIPL PHYS DR
IPC: H01L29/207
Filed: 1984-05-29
Abstract: Conventional dopants for semiconductor materials, such as boron or phosphorus in silicon, have the disadvantage that charge carriers freeze out in the doping centres at low temperatures and the conductivity is considerably reduced. This disadvantage of conventional dopants is eliminated by heterodoping with three-dimensional inclusions which are randomly distributed spatially or regularly arranged. In the case of this heterodoping, the doping centres are isolated in three-dimensional insulator inclusions by interfacial barriers of surrounding semiconductor material (see Figure 1). The doping centres are situated energetically above the conduction band edge of the semiconductor. As a result, charge carriers are emitted from the doping centres into the conduction band and freezing-out of the charge carriers in the doping centres at low temperatures is prevented. Inclusions having the properties mentioned are produced, for example, by precipitating SiO2 in oxygen-rich silicon after long-term annealing at 650 DEG C. SiO2 can be doped by means of positively-charged inherent defects (free oxide charge) or by controlled doping with alkali ions. Doping centres below the Si conduction band edge in the interfacial region are reduced by a hydrogen treatment. Other suitable precipitates, for example Si3N4, are possible. <IMAGE>

Title: Method for limiting the electrical field energy or potential differences along gas lines which carry voltage
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: H01M8/04089
Filed: 1984-07-09
Abstract: On an earthed pipe 1 which consists of insulating material, which carries explosive gas mixtures away from a fuel-cell or accumulator battery 2, the risk of gas explosions can be avoided by segmenting the pipe by means of metallically conductive connecting pieces 3 and parallel connection of the pipe segments by means of current-limiting or voltage-limiting components, such as electrical resistors R1, R2, R3...R10. This risk exists when, for example as a result of electrode fracture, the pipe is entirely or partially filled with electrolyte and is in consequence electrochemically coupled to the battery, which can result in a potential drop of up to several hundred volts over the entire pipe length, with electrolyte decomposition and spark formation at the points where the electrolyte film tears apart. As a result of the wiring connection, possible section voltages are in this case limited to at most 30 volts, which is not sufficient to bring about a field intensity required for ignition of the gases. <IMAGE>
