  • Patent number: 5577884
    Abstract: An improved turbine vane structure is disclosed which enables more effective cooling and the reduction of temperature gradients along its length. The hollow interior of the vane is divided into three separate cavities, two upstream cavities and a downstream cavity. The downstream cavity is partially filled with a body of porous, heat transfer material. Cooling air flows through the downstream cavity in a direction counter to the hot gases passing over the exterior surface of the vane so as to increase the heat exchange properties. The two upstream cavities lie adjacent to each other and are supplied with cooling air from opposite directions to achieve a counterflow, heat exchange effect. Several sets of cooling holes are provided through the vane wall to communicate with the interior cavities and supply cooling air to the exterior surface of the vane.

  • Patent number: 5568696
    Abstract: This invention relates to a magazine for a repeater firearm, preferably for an automatic pistol which, while approximately preserving its external dimensions, is modified so that the usable capacity inside the magazine is reduced. In one refinement, the invention relates to a magazine with a magazine tube (1), a magazine spring (4), a feeder (7) and a magazine base (2). To reduce the usable capacity of the magazine, a spacer (6) is attached to the magazine base (2) facing the magazine spring (4). The magazine spring (4) is also shortened so that, in the absence of the spacer (6), it does not exert sufficient force on the feeder (7) to reliably advance the last cartridges (9) to the magazine lips on the end of the magazine tube (1). In addition to or instead of the features described above, the spacer (6) can be designed so that in its absence, and if the magazine is filled with bullets, the magazine base is partly or completely detached from its mounting on the other end of the magazine tube (1).
