Title: Vehicle spring brake unit - has sliding release lug and component yielding under shock load only
Inventor: COUPLAND RALPH
IPC: B60T17/08
Filed: 1974-12-10
Abstract: The unit has a spring-loaded piston in a housing, coupled to the brake so as to apply it in the event of air pressure failure. It is released after operation by a mechanism incorporating a lug sliding axially so as to engage with the piston and thrust it against the action of a spring. A distorting or breakable component is included, which withstands the normal load when releasing the brake, but yields under shock-loading, thus absorbing much of the energy of the spring should this "explode" on dismantling and reducing the risk of injury.

Title: Low-temperature tar - extracted free from water/light oil from crude gas by water/tar scrubbing in two stages
Inventor: OTTE ERNST
IPC: C10B47/24
Filed: 1975-02-26
Abstract: A low-temp. tar is extracted from a crude gas, produced by low-temp. carbonisation in an indirectly heated fluidised bed. In a first stage, the crude gas is cooled by spraying with wash water and tar and the tar is separated. The gas is cooled further by wash water sprays in a second stage and discharged with the light oil; the tar separated in the second stage is recycled to the frist and a part of the tar separated in the first stage is passed on for futher processing. This process a low-temp. tar of better quality because it is completely free from the water and light oil components of the crude gas.

Patent DE-2527766-A1 (DE)
Title: Anti corrosion coating for conductor rails - has metal or plastic ring on corrugation rim to reduce stress when hose is under pressure
Inventor: VEGELAHN FRITZ
IPC: B60M1/12
Filed: 1975-06-21
Abstract: The pantograph of the tracked vehicle, or the electric pick-up system, is fitted with a set of spraying jets which spray a protective fluid over the conductor rails. This prevents the oxidation of the rails and the build up of a layer of aluminium hydroxide. The fluid is forced out of a pressurised reservoir by compressed air from a pump controlled by an electro-magnetic valve. The build-up of the aluminium hydroxide increases the pantograph resistance and leads to arcing. This roughens the surface of the rails and leads to wiper bar wear, especially at night under moist air conditions. The protective fluid is a low ash residue oil which stays fluid over long periods.
