Abstract: An ebullient cooling system employs a thyratron or other power device which is located within a hollow of a housing. The housing contains a liquid which completely surrounds the device. The liquid is of a type which provides high electrical insulation and which boils at a temperature compatible with the desired operating temperature of the thyratron. A heat exchanger is contained in the housing and is located above the liquid level. The heat exchanger is adapted to receive vapors which are produced when the device is operating and serves to condense the vapors back to a liquid to return the same to the reservoir. The power device is thusly cooled by the latent heat of vaporization and by the action of the heat exchanger when condensing the vapors back to a liquid.

Abstract translation: 沸腾的冷却系统采用位于壳体的中空部内的闸流管或其他动力装置。 外壳包含完全围绕设备的液体。 该液体是提供高电绝缘性并且在与闸流管的期望工作温度相适应的温度下沸腾的类型。 热交换器被容纳在壳体中并且位于液面之上。 热交换器适于接收在装置运行时产生的蒸气，并用于将蒸气冷凝回液体以将其返回到储存器。 因此，通过蒸发的潜热和通过将蒸气冷凝回液体时由热交换器的作用来冷却功率器件。

Abstract: A system for helically wrapping a tape comprises tape twisting means, and, upstream of the twisting means, means for shaping the tape. The shaping means comprises a body over which the tape passes, the body having a first surface of at least partially cylindrical form and an outwardly curved edge surface extending along a side of the first surface. Tape supply means is arranged to feed the tape onto the first surface such that the tape is inclined to a plane at right angles to the axis of the first surface whereby an edge of the tape engages the curved edge surface and is thereby shaped in order to initiate wrapping. The system is particularly suitable for wrapping a paper tape around a nylon core.
