Patent DE-2403747-A1 (DE)
Title: Piston for hydropneumatic shock absorber - has radial fluid flow to decrease surface agitation
Inventor: OVERKOTT FRANZ
IPC: F16F9/34
Filed: 1974-01-26
Abstract: The piston (1) is fixed on its lower surface to the piston shaft. The upper surface carries a diametral, shallow, groove (10) in which are positioned two pairs of holes (16) passing through the piston, one pair each side of the piston centreline. A support block (8) is mounted with its convex face in the piston groove and holds a spring plate (5). When the piston is moved down, fluid flows from the lower part of the shock absorber, through the piston holes, pushes the spring plate against the support block, and flows radially into the upper part. This decreases the agitation on the fluid/gas interface in the upper part and decreases gas adsorption.

Patent DE-2437567-A1 (DE)
Title: Sealing ring gasket arrangement - has ring of same area as groove but different shape
Inventor: TUECKMANTEL HANS-JOACHIM DIPL
IPC: F16J15/10
Filed: 1974-08-03
Abstract: After tightening the ring normally flattens out, so that any initial imperfections on the ring tend to be more marked on the increased ring surface, resulting in not quite satisfactory seals. The present concept chooses pliable sealing rings set in grooves on the surface of one, or both flanges, the cross section of the ring in the initial condition is smaller than in the final tightened condition. The ring deforms in such a way that it completely fills the groove and the deformation takes place at constant volume. The grooves can be of rectangular or circular cross section and so can the sealing rings.

Title: Oscillographic ferrometer with single-layer ellipsoidal solenoid - has rectangular solenoid turns such that homogenous field zone is large
Inventor: MOGILEWSKY WITALY MORITSOWITSC
IPC: G01R33/14
Filed: 1975-01-09
Abstract: The oscillographic ferrometer has a magnetizing means including a step-down transformer and a single-layer ellipsoidal solenoid connected to a single-turn secondary winding of the step-down transformer and having a constant turns density along the generatrix. The solenoid receives a test sample. Magnetization and magnetizing field measuring channels cooperate with the magnetizing means. The relationship of the geometrical dimensions of the ellipsoidal solenoid having rectangle-shaped turns provides for a mutual compensation effect at the central region with respect to the end field decay caused by the solenoid pole truncation and a field augmentation gained due to the ampere-turns density axial component growing from the solenoid centre towards the pole ends.
