Title: Vehicle steering ram control mechanism - has distributor component turning and sliding on fixed axis
Inventor: VACCARI LAURO
IPC: B62D5/097
Filed: 1978-10-07
Abstract: The vehicle steering system has a ram with an engine-driven pump with internally toothed gear, and a rotary actuator. A pressure distributor has fixed (1) and moving (3) components joined together to form a seal. The moving one turns and slides on a fixed axis. A transmission member (10) can only turn on this axis and is coupled directly to the internally toothed gear. Shaft, moving distributor and transmission member are coupled so that shaft and component rotate together, and relative rotation between member and shaft corresponds directly with sliding of the component. The fixed component has an inlet (18) which can be connected to the pressure source, and also a return outlet for the fluid, together with two unions (22a, 22b) leading to the ram. Passages in the fixed and moving components connect the ram to the pressure source and return, or cut it off when in the rest position.
Patent DE-2845269-A1 (DE)
Title: Reinforced laminated plastic check for moisture penetration - by embedded capacitive pick=ups
Inventor: PETTERS CLAUS ING GRAD
IPC: G01N27/22
Filed: 1978-10-18
Abstract: Laminations of several layers of resin-impregnated glass fibre tissue, which are e.g. used for hulls of boats and ships, suffer a reduction, esp. in tensile strength, if moisture penetration causes them to age. This can be checked by incorporating during the laying up of the webs several planar capacitive pickups between the laminations; the connecting wires are led out to the selvedge and grouped in plug connectors. Each pickup consists of a rectangular piece of hygroscopic material, e.g. filter paper, which stands out beyond the two plastic foils, enclosing it and carrying metal foil linings with the attached connecting leads. This causes little extra work during fabrication and allows a continual check of any moisture penetration. This method is more reliable than weighing the reinforced sandwich.

Title: Self adhesive filing strip - is made in two kinds and used to repair sheets with torn out filing holes or to attach sheets to back or others
Inventor: WENDT RUEDIGER
IPC: B42D1/10
Filed: 1978-12-14
Abstract: Self-adhesive filing strips used for the repair of sheets the filing holes of which are torn.

Title: Video testing of transparent container rims for defects - compares chord length signals derived from video image
Inventor: MARGUERRE HANS-HELMUT DIPL PHY
IPC: G01N21/90
Filed: 1979-04-23
Abstract: The method and device are for checking the rims of transparent containers for damage and involve using video cameras to produce chord length signals which are compared with desired values.
