Title: Ball valve for perishable food - with upstream ball sealing disc receiving full hydrostatic pressure
Inventor: KIRCHHOFF-STEWENS LOTHAR DIPL
IPC: F16K5/06
Filed: 1979-06-15
Abstract: A ball valve has a spherical plug which is coupled to the drive spindle. The ball itself is located in the valve housing between two coaxial sealing discs which contact the ball with a certain preload. The housing for the sealing disc at the inlet side of the ball valve is so designed that the area of the sealing disc opposite to the area contacting the ball receives the full force of the pressure of the cut-off liq. This surface area of the inlet sealing disc is at least equal to, but preferably greater than the clear passage area of the sealing disc. This creates a ball valve in which any detrimental effect of deposits has been eliminated The valve is therefore ideal for perishable food such as chocolate where deposits may spoil later batches. Both sealing discs are now kept firmly pressed against the ball.

Title: Permanent magnet based switched brake - creates eighteen kilo-gauss field using rotating ferrite magnets
Inventor: BAERMANN MAX
IPC: F16D65/14
Filed: 1979-08-03
Abstract: The braking system uses permanent magnets using eddy current effects and/or friction forces for railway vehicles and eddy current effects only for road vehicles. Part of the permanent magnet system is rotated through 90 deg. to give the braking effect by creating a flux density of 18kGauss in a 1mm air gap. This is achieved by using ferrite material including metallic oxides of barium strontium or lead. The brake consists of fixed magnets arranged alternately with the rotating magnets along the axis of the rail, the rotating magnets having pole pieces shaped to follow the air gap profile in the braking condition. The rotating magnet axis is perpendicular to the rail and is defined by a central cogged shaft through which they are rotated.
