Patent DE-3613654-A1 (DE)
Title: Electronic room temperature control system
Inventor: BUSSE HEINZ-GERHARD DIPL PHYS
IPC: F24D19/10
Filed: 1986-04-23
Abstract: A system consisting of room temperature controllers and a central unit is described which is capable of controlling the individually selected temperature of each room of an arbitrary centrally heated building. The system employs no outside temperature sensor, but receives the information for controlling feed temperature and boiler temperature directly from the room temperature controllers in the individual rooms. The system employs no learning algorithms, but requires that each room temperature controller is connected to the central unit via a data line (three wires); a corresponding network has, however, already been generally accepted for telephones and power supply. Also described is a variation of the system for the automatic control of off-peak storage furnaces having the same advantages. It is possible as a result to take account of influences such as waste heat, variable insolation, weather influences, etc. as well as individual habits and requirements of the occupants in a full and uncompromising fashion.

Patent DE-3641534-A1 (DE)
Title: Circuit for transmitting control commands and measured values of a mining machine for underground use
Inventor: PODESCHWA DIETER DIPL ING
IPC: E21C35/24
Filed: 1986-12-05
Abstract: In underground working, the control commands and the measured values are transmitted via a control line or via the energy supply line of the mining machine by means of control frequencies. Disturbances influence the signals, in terms of their quality and strength, on this transport path and make their transmission more difficult. The aim of the invention is to transmit such information even over large distances and to suppress and compensate the disturbances which occur in the process, as well as the intensity losses at the receiving by means of the circuit according to the invention. As a solution, it is proposed to superimpose, in the receiver (8), an oscillator frequency on the input frequency which transmits the measured values or control commands, to raise the input frequency into a frequency range which is suitable for particularly effective filtering and to restrict this frequency range to a narrow-band range which corresponds to the input frequency, and to amplify it. <IMAGE>

Patent DE-3701811-A1 (DE)
Title: Method and apparatus for producing a single crystal
Inventor: HAIDA OSAMU
IPC: C30B15/30
Filed: 1987-01-22
Abstract: In the Czochralski method of growing single crystals of high-purity silicon, a magnetic field which travels downwards is applied to the silicon melt in the melting crucible and a topping-up amount of polycrystalline silicon is introduced into the melt to compensate for the decrease in the volume of the melt in the melting crucible due to the growth of the single crystal. The purpose of the magnetic field is to keep the doping concentration in the melt at a constant level. Compared with the prior-art method in which no travelling magnetic field is applied, the silicon single crystal produced by the method according to the invention is advantageous in relation to the substantially smaller variation in the resistivity in the plane of wafers produced by cutting up the single-crystal body.

Patent DE-3719457-A1 (DE)
Title: Dryer for agricultural products or other materials
Inventor: BUCK KONRAD DR
IPC: F26B9/10
Filed: 1987-06-11
Abstract: The dryer serves for drying stacked forage from arable and grassland. It consists of distributors (5), to which drying air is supplied, a relatively large number of probes (29) projecting from the bottom (7) of each distributor (5), which conduct drying air into the material to be dried. In a known dryer, every probe is pushed with its collar into a holder arranged on the bottom and is secured there. On the known dryer, it is disadvantageous that the small play necessary in the holder for pushing each probe impairs the transmission of a vibration from the distributor to the probe. The probes are, however, accurately to adopt the vibration of the distributor brought about by a vibrator in order that they can be introduced into a material which is difficult to penetrate. In the dryer according to the invention, individual parts of the chamber-type distributor (5) are interconnected in a sealed and detachable manner and each probe (29) can be fastened on the bottom (7) in a play-free manner, as a rapid connection, by at least one insertion disc (28), the collar (112) arranged on the probe (29) representing an abutment for the insertion disc (28). <IMAGE>
