Title: Mine-working area ventilation and air conditioning - involves use of evaporation cold by condensing fresh air current moisture and reheating
Inventor: HENTING HANS
IPC: E21F3/00
Filed: 1979-07-26
Abstract: A current of fresh air in the base gallery, in the area of transition to the working face, is led through the latter and removed via the head gallery in the form of contaminated air, to ventilate a working area in a mine. Use is made of cold caused by evaporation emanating from water existing or occurring in the working area, by cooling the fresh air current to approx. 5 deg. C. Water condensing from it is released and heated to pref. approx 20 deg. C. Relative humidity of approx. 30-40 % occurs, and the air current, thus dried, is conveyed into the working area. Pit air and climate adequate for all demands are produced without difficulty.

Title: Submerged arc welding of branch pipes onto main pipes - where main pipe is rotated through semicircle so molten weld pool is always horizontal to preclude run-out(s)
Inventor: RUSSELL DIETRICH DR ING
IPC: B23K9/032
Filed: 1980-02-08
Abstract: A branch pipe is to be welded onto a main pipe or a cylindrical vessel. Pipe is tack welded onto the pipe or vessel, and then a rotor is inserted in pipe and used to rotate a welding burner through 360 deg. to make the weld. During the welding operation, the vessel or pipe is rotated on its axis through an arc of 180 deg. so the welding zone below burner is always in a horizontal position. The result is that the molten weld pool and its powder covering do not run away when pipes have an outside dia. ratio d/D above 0.6; where d is the outside dia. of the branch pipe and D is the o.d. of the main pipe. With the invention, d/D can almost equal 1.0.

Title: Process and equipment for decontaminating objects contaminated with chemical warfare agents
Inventor: GOERGENS KURT
IPC: A62D101/02
Filed: 1981-01-28
Abstract: A description is given of a process for decontaminating objects contaminated with chemical warfare agents. In the process, the chemical warfare agent is stripped from the object by a solvent, preferably perchloroethylene. The solvent containing chemical warfare agents is then brought into intimate contact with a detoxification chemical, preferably calcium hypochlorite. The detoxification agent, chlorine, which is formed removes the chemical warfare agent from the solvent which can therefore be used again for a subsequent decontamination (recycling process). Pieces of equipment are furthermore disclosed with which the solvent, perchloroethylene, can be brought into intimate contact with the detoxification chemical, calcium hypochlorite at relatively low cost, chlorine being enriched as oxidising agent in the organic phase throughout the reaction section. <IMAGE>

Title: Steering device for motor vehicles
Inventor: OSTWALD FRITZ DIPL PHYS
IPC: B62D5/00
Filed: 1981-05-27
Abstract: In a steering device with derivative action time or hold time for motor vehicles, a steering movement portion is positively or negatively superimposed on the steering movement which is transmitted to a steering gear as a function of the rotation angle of a steering wheel, which steering movement portion depends on the respective angular speed of the steering wheel. A shaft end (1) which is connected to the steering wheel is arranged coaxially but rotatably with respect to a shaft end (3) which is connected to the steering gear. The two shaft ends (1, 3) each bear a wheel (4 and 5, respectively) with different steep-lead-angle threads (6, 7). The two steep-lead-angle threads (6, 7) engage with a coupling sleeve (8) which is axially displaceable by an actuation piston (26, 26') in order to bring about a relative rotation between the wheels (4, 5) which is superimposed on the steering movement. The actuation piston (26, 26') is controlled by a hydraulic control valve which is acted on by hydraulic pressures which are supplied by a gear wheel pump (13) which is connected to the steering wheel. The said hydraulic pressures correspond to the angular speed of the steering wheel. The actuation piston (26, 26') can be arranged in the control valve or concentrically surround the coupling sleeve (8). <IMAGE>
