Patent DE-2333446-A1 (DE)
Title: Balance-spring outer end fastening - is for use with synthetic material particularly in electric clocks
Inventor: WOLBER ROBERT
IPC: G04B17/32
Filed: 1973-06-30
Abstract: The outer end of the balance spring is fastened to a projecting part of the synthetic material from which the clock frame is made by placing the end in position and plasticising the synthetic material. The end of the spring may be placed in a slot in this projection, and the shoulders may be plasticised and peened over by ultrasonic welding. The fastening is improved if a notch is cut in one edge of the end of the spring where it is to be fastened. This avoids the problems of gluing, where the glue had to be kept warm or out of contact with air and where there is a danger of contamination of other parts of the mechanism. The welding may be removed during repair and traditional methods of gluing still employed.

Title: Sludge squeezing in double drum with partitions between - which execute rolling motion to knead sludge
Inventor: WEHNER ALBERT
IPC: B30B9/20
Filed: 1974-02-23
Abstract: A device for concentrating or filtering out solids, esp. for compressing sludge, comprises two drums, one mounted eccentrically inside the other so that the annular space between is of varying width. Flexible partitions extend between the two drums, dividing this annular space into compartments; as the two drums revolve, the change is size of the compartments squeezes out liquid (or gas) from the sludge through holes in teh radial walls of the chambers. The arrangement is such that, if the annular space is considered as subdivided into 4 quadrants by two perpendicular axes of which one passes through both the drum axes then the first quadrant in the direction of rotation from this axis through the two drum axes contains a stretched flexible wall, the second and third quadrants contain relaxed walls folded onto one of the drums and partly obturating the holes in that drum, while in the fourth quadrant the flexible partitions start to stretch again. The points of attachment of the flexible walls are pref. at offset positions on the two drums, one of the drums being rotationally driven while the other drum is pulled round by it. The sludge is kneaded by the moving flexible partitions. The escape holes do not become clogged. The appts. is therefore suitable for sticky sludges.

This accelerator can be coupled to a television camera and a drive for aiming purposes and for firing. The linear accelerator consists of n series connecting solenoids each of which has a body, a winding, insulating discs, a collector ring and a main winding. The start of the solenoid is electrically connected to the earthing ring, the other end of the solenoid is insulated and this end is connected to the associated output of a power amplifier. The penetration power of the projectile can be adjusted, which is of especial importance in aircraft whose fuselage skin must not be pierced.
