The getter-ing device comprises a source of evaporable gettering metal and at least one gas source of a material releasing gas upon heating.  The gas-releasing material consists at least substantially of a nitrided pulverulent ternary alloy of iron, germanium and at least one of the metals chromium and manganese.  Such a gas-releasing material can be exposed to moist air of 450°C for at least one hour without any objec-tion, which conditions occur when the window portion and the conical portion are sealed together.

Abstract: ABSTRACT         Apparatus and method are disclosed by which toe is mea-sured relative to a vehicle centerline or a nonsteerable wheel rolling direction for all four wheels on a vehicle having a pair of front steerable wheels and a pair of rear nonsteerable wheels.          An alignment head is placed on one of the front wheels and another alignment head is placed on one of the rear wheels, both wheels being on the same side of the vehicle.  The alignment heads pro-ject a beam pattern across the vehicle at the front and the rear.          Reflectors are mounted on the other wheels at the front and the rear to intercept and reflect the beams back toward detectors in-cluded in the alignment heads.  A beam pattern is also projected rearwardly along the length of the vehicle chassis from the align-ment head mounted on the front wheel.  A rear wheel mounted reflec-tor intercepts the rearwardly projected beam pattern and reflects it back toward a detector in the front wheel mounted alignment head.  Structure is provided on each of the rear wheels which pro-vides an optical path which may be directed toward points at the front wheels which are equidistant from a center point between the front wheel pair.  Measurements of total toe for each wheel pair and of individual toe for each wheel are obtained through use of the disclosed structure and process.

Abstract: ABSTRACT OF THE DISCLOSURE Centre buffer couplings are articulated on vehicle frames to permit the easy negotiation of curves and switches.  To allow this the coupling head extends beyond the vehicle buffers and is connected to a coupling rod.  The hazard to other vehicles travelling over the same rails caused by the protruding coupling head is eliminated by providing the coupling rod with a joint permitting horizontal swivelling of the head.  A sleeve, cooperating with a cam, allows the joint to be made rigid or free, dependent upon the position of the sleeve and the setting of the cam.
